Trial site(s):
Multi-centre trial in 1 up to 10 countries
Clinical phase:
Phase Ia/Ib
Objective(s):
Dose escalation part (Phase Ia)
To investigate the maximum tolerated dose (MTD) through dose limiting toxicities 
(DLTs), safety and tolerability, pharmacokinetics, f
 biomarker and 
efficacy of BI 894999 monotherapy in patients with advanced and/or metastatic solid 
tumours in three different schedules (Schedule A with continuous dosing, Schedule B 
with two weeks on treatment and one week off in 3-week cycles, Schedule C with a 
loading dose on Day 1 followed by a maintenance dose on the six next days and a 
week off, repeated every two weeks in 4-week cycles) and provide safety data in 
terms of drug-related adverse events (AEs) for the recommendation of the dose and 
schedule of treatment for the expansion Phase Ib of this trial (between Schedules A 
and B) and for further trials in the development of BI 894999 (between Schedules B 
and C).
To determine the MTD in patients with diffuse large B-cell lymphoma (DLBCL) 
once the MTD has been determined for both schedules A and B in patients with solid 
tumours, (Schedule B was selected based on Schedule A and B data according to the 
Data Monitoring Committee (DMC) recommendation). The MTD will also be 
determined for Schedule C in DLBCL patients. Once both MTDs for Schedule B and 
Schedule C are determined for DLBCL, the DMC will recommend the best schedule 
and dose to be used for the extension of MTD cohort in DLBCL patients.
Expansion part (Phase Ib)
To further collect safety information, PK and anti-tumour activity at the 
recommended dose and schedule in patients with solid tumours to confirm the RP2D

in patients with solid tumours and for Schedules B and C in the DLBCL 
cohort
-
Objective Response (Complete Response (CR) and Partial Response (PR)) 
according to RECIST version 1.1 as assessed by the investigator throughout 
the entire treatment period for each schedule in patients with solid tumours

Phase Ia solid tumours, the following endpoint will be assessed:
-
Number of NC patients in the Schedule C cohort experiencing DLTs from 
start of treatment until end of treatment (in all cycles) as assessed every 4

Safety criteria:
Adverse events (AE) according to CTCAE v. 4.03, incidence of DLTs, determination 
of MTD, laboratory evaluations, vital signs, electrocardiograms (ECG), left 
ventricular ejection fraction (LVEF).
Statistical methods:
For the primary endpoint in the Phase Ia part of this study, a Bayesian logistic 
regression model (BLRM) with overdose control will be fitted to binary toxicity 
outcomes. The estimate of parameters will be updated as data are accumulated using 
the BLRM. At the end of the Phase Ia part for Schedules A and B, the toxicity 
probability at each dose level was calculated to determine the MTD. The analysis of 
the primary endpoint of the Phase Ia part happened once the last entered patient with 
solid tumour from Schedules A and B reached Day 22 of the first cycle and was 
evaluable for DLT occurrence or not in the first cycle.
Results of the primary endpoint of the Phase Ia part in patients with solid tumours for 
Schedule C and for DLBCL patients in Schedules B and C are planned to be reported
with final analysis of the trial.
For the primary endpoint in the Phase Ib part of this study, the number of patients 
with DLT during the entire treatment period will be summarized by cohorts. The 
analysis of the primary endpoint of the Phase Ib part will happen together with the 
final analysis when the last ongoing patient will have reached 4 cycles of trial 
treatment or stopped trial treatment and will have performed the end of residual effect 
period (EOR) visit, at least 30 days after last trial drug intake, whatever occurs first.
An updated report will then be written once the last ongoing patients will have 
reached the end of trial.
Exploratory analyses and descriptive statistics will be used for secondary endpoints

of toxicity, pharmacokinetics (PK) parameters, and efficacy. 
 
 
 
 
 
For the Phase Ib part, a 2-stage Bayesian hierarchical model approach will be 
implemented with an interim futility assessment conducted when approximate 9 
patients are enrolled and treated in each of the SCLC, mCRPC and CRC patients’ 
cohorts. If no objective response is observed in the 9 first patients evaluable for 
efficacy in a cohort with Schedule B, then this cohort will be closed for the stage 2 of 
the phase Ib part. For the response endpoints (i.e. objective response, disease control) 
in the Phase Ib part, a Bayesian hierarchical modelling approach with a scale 
parameter for the inter-cohort variability will be used. The prior for the inter-cohort 
variability will be chosen as half-normal with a scale parameter of 100. Thereby the 
shrinkage estimators allowing borrowing information from different patient cohorts
will be considered (response data from the MTD expansion cohort of DLBCL will 
also be considered in the Bayesian hierarchical model). Additionally descriptive 
statistics of these endpoints for the specific cohorts will be provided.

Pre-dose sampling will be conducted at Days 8 and 12 just before drug administration of the dose
17 one blank urine will be collected prior to the BI 894999 intake on visit 1 and visit 4 (at least two 2 mL aliquots). 
In addition urine will be collected as summarized in Appendix 10.2
18 all AEs and concomitant medication must be collected until 30 days (until EOR) after the last BI 894999 intake. 
After EOR, for subsequent FU visits, only SAEs/AESIs which are considered study drug related need to be 
collected as well as their related treatment
19 according to RECIST 1.1 guidelines for patients with solid tumours (including mCRPC patients who have
measurable disease). Imaging and assessment are required every 2 cycles (meaning every 6 weeks if no delays in 
cycles but as close as possible to the end of the second of the two cycles of treatment if there was a delay). 
For mCRPC patients, in addition to the CT/MRI every 2 cycles, a bone scan has to be performed at screening 
and then every 4 cycles (every 12 weeks if no delays in cycles) with a PSA evaluation at the same time-points as 
the bone scan. 
According to RECIL 2017 guidelines for DLBCL patients, a fluorodeoxyglucose positron emission-tomography 
(FDG-PET coupled to a computed tomography (CT) scan (or MRI if CT not possible but each time, same 
method) must be performed at screening, at the end of Cycle 2 (at 6 weeks if no delays in cycles), at the end of 
Cycle 4 (week 12) and then every 4 cycles. In patients with negative FDG-PET uptake in the bone marrow at 
screening, a bone marrow aspirate and biopsy need to be performed in order to rule out bone marrow 
involvement. 
EOT/FU imaging and assessment are optional if previous examination was performed in the past 4 weeks
20optional for patients in the escalation phase including the patients in the extension of MTD cohort who agree to 
tumour biopsy, and mandatory for patients in the solid tumour expansion Phase Ib, a tumour biopsy for 
biomarker analysis (see 5.5.1.2) must be performed at baseline and between Day 11 and Day 14 of Cycle 1: the 
biopsy may only be performed if the platelet count is above 50 000/mm3 (coagulation must be checked on the 
day of the biopsy). For those patients having a tumour biopsy at steady state, a mandatory 2-3 mL EDTA DNA 
blood sample must be taken at the same time as the tumour biopsy, at steady state. In Phase Ib, for mCRPC

11 update only
12 according to RECIST 1.1 guidelines for patients with solid tumours (including mCRPC patients who have a
measurable disease). Imaging and assessment are required every 2 cycles (meaning every 6 weeks if no delays in 
cycles but as close as possible to the end of the second of the two cycles of treatment if there was a delay). EOT/ 
FU imaging and assessment are optional if previous exam was performed in the past 4 weeks. The choice of 
computed tomography (CT) and/or magnetic resonance imaging (MRI) is left to the investigator’s judgement but 
the method must remain the same for all evaluations. If the patient did not end the trial treatment due to 
progressive disease (PD), the tumour assessments during follow-ups will be according to standard of care for the 
site/country. 
For mCRPC patients, in addition to the CT/MRI every 2 cycles, a bone scan has to be performed at screening 
and then every 4 cycles (every 12 weeks if no delays in cycles) with a PSA evaluation at the same time-points as 
the bone scan.
According to RECIL 2017 guidelines for DLBCL patients, a FDG-PET coupled to a CT scan (or MRI if CT not 
possible but each time, same method) must be performed at screening, at the end of Cycle 2 (at 6 weeks if no 
delays in cycles), at the end of Cycle 4 (week 12) and then every 4 cycles. In case a complete response is 
observed, a BM aspirate and biopsy have to be performed for confirmation of CR
13 If a patient has an objective response or is benefiting from the treatment and he/she agreed beforehand for 
   sending of archival tumour tissue or/and for a fresh tumour biopsy (if deemed safe and feasible by the 
   investigator) for gene analysis, 2-3 mL EDTA DNA blood tube at any time during response
14 For each ECG, digitalized triplicate acquisition using dedicated equipment for central reading by clinical 
research organization (CRO). The ECGS are to be performed before the blood sampling when at same time-
point as blood sampling (see 5.4.2)
15 to be performed at the end of Cycle 2 by echocardiography or MUGA scan, by the same method as at baseline
16 to be performed if not done in the past 6 weeks and if possible, according to the patient’s  condition at the time 
of EOT
17 measurements of CK and troponin and any other parameter deemed necessary to be controlled by the 
investigator
18 including measurements of coagulation parameters: aPTT, PT expressed in seconds and INR

13 When a blood glucose test is performed, the investigator must indicate whether the patient was in fasting 
condition at the time of the blood sampling, meaning the sample is taken after an overnight fasting. Safety lab 
parameters including coagulation parameters (aPTT, PT expressed in sec and INR) only to be performed at 
screening, on Day 1 pre-dose, on Day 2, Day 8, pre-dose on the day of tumour biopsy when applicable (if on a 
different day then Day 8), on Day 14 and at EOT. Each time a safety lab is foreseen per protocol, troponin hs 
test must be performed (T hs or I hs but always the same test for a given patient).
13a In the first 20 patients to be entered in phase Ib after approval of protocol version 7.0, coagulation factors II, V, 
VII and IX will be measured on C1D1 pre-dose, on C1D14 pre-dose and on C2V1D1 pre-dose. 
13b Hep B DNA test, Hep C RNA test and HIV infection detection by an established HIV diagnostic assay 
performed at screening (results within 4 weeks before screening are acceptable) .
14 only in patients with tumour types where there is a clinically relevant tumour marker which is already used in 
routine clinical practice for tumour restaging (on Day 1 of every cycle). PSA mandatory for mCRPC patients
15 urine examination by dipstick for pH, glucose, erythrocytes, leukocytes, protein, nitrite. If pathological findings, 
further evaluation (see Section 5.3.3)
16 intensive PK blood sampling will be performed in Cycle 1, as summarized in Appendix 10.2
For the food interaction cohorts, same PK time points as for other patients with in addition on Day 2: 0:30min, 
1h, 2h, 3h, 4h, 6h, 8h 24h (Days 2) post-dose and on Day 3: 24h post-dose of Day 2 (see 10.2.2)
Pre-dose sampling will be conducted at Days 8 and 12 just before drug administration of the dose
A PK sample will also be taken at the time of the visit on Day 18
17one blank urine will be collected prior to the BI 894999 intake on visit 1 and visit 4 (at least two 2 mL aliquots). 
In addition urine will be collected as summarized in Appendix 10.2
18 all AEs and concomitant medication must be collected until 30 days (until EOR) after the last BI 894999 intake. 
After EOR, for subsequent FU visits, only SAEs/AESIs which are considered study drug related need to be 
collected as well as their related treatment
19according to RECIST 1.1 guidelines for patients with solid tumours (including mCRPC patients who have a
measurable disease). Imaging and assessment are required every 2 cycles (meaning every 6 weeks if no delays in 
cycles but as close as possible to the end of the second of the two cycles of treatment if there was a delay). 
EOT/FU imaging and assessment are optional if previous examination was performed in the past 6 weeks
For mCRPC patients, in addition to the CT/MRI every 2 cycles, a bone scan has to be performed at screening 
and then every 4 cycles (every 12 weeks if no delays in cycles) with a PSA evaluation at the same time-points as 
the bone scan.
According to RECIL 2017 guidelines for DLBCL patients, a FDG-PET/CT scan (or MRI if CT not possible but 
each time same method) must be performed at screening, at the end of Cycle 2 (at 6 weeks if no delays in 
cycles), at the end of Cycle 4 (week 12) and then every 4 cycles. EOT/ FU imaging and assessment are optional 
if previous exam was performed in the past 6 weeks
20aoptional for patients in the escalation phase including the patients in the extension of MTD cohort who agree to 
tumour biopsy and mandatory for patients in the expansion Phase Ib, a tumour biopsy for biomarker analysis 
(see 5.5.1.2) must be performed at baseline and between Day 8 and Day 11 (4-8hrs after drug intake) of Cycle 1: 
the biopsy may only be performed if the platelet count is above 50 000/mm3 without support from a transfusion
and coagulation parameters (aPTT, PT in sec and INR) are within normal limits on the day of the biopsy. The 
baseline biopsy may be replaced by the sending of archival tumour tissue from a biopsy performed at the latest 
progression and not older than 6 months. For those patients having a tumour biopsy or sending of archival 
tumour tissue, a mandatory 2-3 mL EDTA DNA blood sample must be taken once, at any time, being it at 
screening or with steady state biopsy. In Phase Ib, for mCRPC patients with only bone metastases and for NC
patients, tumour biopsies are not requested (remain optional) as well as for patients with therapeutic INR 
because of treatment with a vitamin K antagonist or a novel oral anticoagulant. The on treatment biopsy may 
remain optional if no easily accessible lesions are available
20bif abnormal coagulation parameters and/or a platelet count below 50 000/mm3 prevent tumour biopsies between 
Day 8 and Day 11 of Cycle 1 in 5 or more of the 20 first patients of Phase Ib in solid tumours, the window for 
tumour biopsy will be moved ahead between Day 3 and Day 8 (4-8hrs after drug intake) in the further entered 
patients. Where a fresh biopsy is taken for the baseline sample the subsequent on-treatment biopsy should be 
taken, where feasible, from the same lesion (not to be considered as a target lesion)
 (or other genes related to MOA) gene expression will be analysed in whole blood as summarized in 
Appendix 10.2
22 to be done if not performed within the previous 6 weeks and if possible, according to the patient’s condition at

progressive disease (PD), the tumour assessments during follow-ups will be according to standard of care for the 
site/country. 
For mCRPC patients, in addition to the CT/MRI every 2 cycles, a bone scan has to be performed at screening 
and then every 4 cycles (every 12 weeks if no delays in cycles) with a PSA evaluation at the same time-points as 
the bone scan.
According to RECIL 2017 guidelines for DLBCL patients, a FDG-PET/CT scan (or MRI if CT not possible but 
each time same method) must be performed at screening, at the end of Cycle 2 (at 6 weeks if no delays in 
cycles), at the end of Cycle 4 (week 12) and then every 4 cycles with interpretation according to RECIL 2017
guidelines. EOT/ FU imaging and assessment are optional if previous exam was performed in the past 6 weeks
13 Gene expression will be analysed in whole blood which must be collected as summarized in Appendix 10.2
14 If a patient has an objective response or is benefiting from the treatment and he/she agreed beforehand for 
sending of archival tumour tissue or/and for a fresh tumour biopsy (if deemed safe and feasible by the 
investigator) for gene analysis, 2-3 mL EDTA DNA blood tube at any time (if not yet done before)
15 to be performed by echocardiography or MUGA scan, by the same method as at baseline
16 to be performed if not done in the past 6 weeks and if possible, according to the patient’s  condition at the time 
of EOT
17 measurements of CK and troponin and any other parameter deemed necessary to be controlled by the 
investigator
18 For each ECG, digitalized triplicate acquisition using dedicated equipment for central reading by clinical 
research organization (CRO). The ECGS are to be performed before the blood sampling when at same time-
point as blood sampling (see 5.4.2)
19 When a blood glucose test is performed, the investigator must indicate whether the patient was in fasting 
condition at the time of the blood sampling, meaning the sample is taken after an overnight fasting. Safety lab 
parameters including measurements of coagulation parameters: aPTT, PT expressed in seconds and INR. Each 
time a safety lab is foreseen per protocol, troponin hs test must be performed (T hs or I hs but always the same 
test for a given patient).Coagulation parameters will be evaluated on V1 and V2 of Cycles 2, 3 and 4 and on V1 from 
Cycle 5 onwards.

16according to RECIST 1.1 guidelines for patients with solid tumours. Imaging and assessment are required every 
2 cycles (meaning every 8 weeks if no delays in cycles but as close as possible to the end of the second of the 
two cycles of treatment if there was a delay). EOT/FU imaging and assessment are optional if previous 
examination was performed in the past 6 weeks
According to RECIL 2017 guidelines for DLBCL patients, a FDG-PET/CT scan (or MRI if CT not possible but 
each time same method) must be performed at screening, at the end of Cycle 2 (at 8 weeks if no delays in 
cycles), at the end of Cycle 4 (week 16) and then every 4 cycles. EOT/ FU imaging and assessment are optional 
if previous exam was performed in the past 6 weeks
17a optional for DLBCL patients in the escalation phase including the patients in the extension of MTD cohort and 
optional for NC patients in Phase Ib, who agree to tumour biopsy, a tumour biopsy for biomarker analysis (see 
Section 5.5.1.2) may be performed at baseline and between Day 18 and Day 21 (4-8h after drug intake) of Cycle 
1: the biopsy may only be performed if the platelet count is above 50 000/mm3 without support from a 
transfusion and coagulation parameters (aPTT, PT in sec and INR) are within normal limits on the day of the 
biopsy. For those patients having a tumour biopsy or sending of archival tumour tissue, a mandatory 2-3 mL 
EDTA DNA blood sample must be taken once, being it at screening or when steady state tumour biopsy is taken. 
17b Where a fresh biopsy is taken for the baseline sample the subsequent on-treatment biopsy should be taken, 
where feasible, from the same lesion (not to be considered as a target lesion)
 (or other genes related to MOA) gene expression will be analysed in whole blood as summarized in 
Appendix 10.2
19 only for NC patients recruited in Phase Ib after approval of protocol version 11.0, the patient’s survival status 
will continue to be collected until death, lost to follow-up or until 12 months after the end of trial, even if the 
patient progressed according to RECIST 1.1 or started with another anti-cancer treatment, according to patient’s 
informed consent
20 to be done if not performed within the previous 6 weeks and if possible, according to the patient’s condition at 
the time of EOT

* Examinations of visit on Day 15 may be performed locally, close to the patient’s home, with all tests done as 
foreseen per protocol and a phone call visit with the Investigator happens to evaluate the patient’s safety, if the 
patient is unable to travel frequently to the site and if allowed per local country regulations
** The Day 1 visit of even cycles, from Cycle 6 onwards may also be performed locally, close to the patient’s 
home with all tests done as foreseen per protocol and a phone call visit with the Investigator happens to evaluate 
the patient’s safety, if the patient is unable to travel frequently to the site. It means that a drug dispensation may 
happen for two consecutive cycles on Day 1 of uneven cycles starting from C5 onwards, after discussion with 
the Sponsor and if deemed safe by the Investigator

1 end of treatment; investigations which have to be performed at the EOT visit (as soon as possible when a patient 
discontinues treatment)
2 FU= follow up visit until progression, lost to follow up, treatment with another anti-cancer drug or end of the 
whole trial as specified in Section 8.6. The first follow-up visit is the End of Residual Effect Period visit (EOR) 
which must happen at the earliest 30 days after the end of treatment (see Section 6.2.3.2)
3 last visit of a cycle may correspond to visit 1 of next Cycle if an additional cycle is indicated
4 data from the last visit of the previous cycle (Day 29) may be used in case examinations were done within the 
past two weeks
5 optional, to perform if needed to follow-up on AEs present/ongoing at previous visit or if not performed at the
  EOT visit
6 ECG must be repeated pre-dose on C2V1 (or CxV1) if C2V1 (or CxV1) happens on a different day than C1V5 
(or last visit of previous cycle)
7 from Day 1 till Day 7 and from Day 15 till Day 21 of a cycle with a loading dose on Days 1 and 15. The doses 
of Day 1 and Day 15 of the cycle are administered on site if applicable (when the patient has an on site visit), all 
other doses are taken by the patient outside the clinical site
8  at any time, only in case of drug related Grade 3 or Grade 4 toxicity, every effort must be made to collect a PK 
sample; date and time of the sample and of the most recent drug intake (before PK sample) need to be recorded 
for such samples
9  all AEs and concomitant medication must be collected until 30 days (until EOR) after the last BI 894999 intake. 
After EOR, for subsequent FU visits, only SAEs/AESIs which are considered study drug related need to be 
collected as well as their related treatment
10 update only
11 according to RECIST 1.1 guidelines for patients with solid. Imaging and assessment are required every 2 cycles 
(meaning every 8 weeks if no delays in cycles but as close as possible to the end of the second of the two cycles 
of treatment if there was a delay). EOT/ FU imaging and assessment are optional if previous exam was 
performed in the past 6 weeks. The choice of computed tomography (CT) and/or magnetic resonance imaging 
(MRI) is left to the investigator’s judgement but the method must remain the same for all evaluations. If the 
patient did not end the trial treatment due to progressive disease (PD), the tumour assessments during follow-ups 
will be according to standard of care for the site/country
According to RECIL 2017 guidelines for DLBCL patients, a FDG-PET/CT scan (or MRI if CT not possible but 
each time same method) must be performed at screening, at the end of Cycle 2 (at 8 weeks if no delays in 
cycles), at the end of Cycle 4 (week 16) and then every 4 cycles. EOT/ FU imaging and assessment are optional 
if previous exam was performed in the past 6 weeks
12 If a patient has an objective response or is benefiting from the treatment and he/she agreed beforehand for 
sending of archival tumour tissue or/and for a fresh tumour biopsy (if deemed safe and feasible by the 
investigator) for gene analysis, 2-3 mL EDTA DNA blood tube at any time, if not yet done before 
13 to be performed by echocardiography or MUGA scan, by the same method as at baseline
14 to be performed if not done in the past 6 weeks and if possible, according to the patient’s  condition at the time 
of EOT
15 measurements of CK and troponin and any other parameter deemed necessary to be controlled by the 
investigator
16 For each ECG, as far as possible, digitalized triplicate acquisition using dedicated equipment for central reading 
by clinical research organization (CRO). The ECGS are to be performed before the blood sampling when at 
same time-point as blood sampling (see Section 5.4.2). When the assessments are performed locally, the ECG 
will not be performed on the central reading ECG device and the ECG tracing must be sent to the site which will 
send it to the Central Reading laboratory for evaluation. 
17 When a blood glucose test is performed, the investigator must indicate whether the patient was in fasting 
condition at the time of the blood sampling, meaning the sample is taken after an overnight fasting. Safety lab 
parameters including measurements of coagulation parameters: aPTT, PT expressed in seconds and INR. Each 
time a safety lab is foreseen per protocol, troponin hs test must be performed (T hs or I hs but always the same 
test for a given patient).
Coagulation parameters will be evaluated only on V1 of each cycle.
18 only for NC patients recruited in Phase Ib after approval of protocol version 11.0 or 12.0 (depending on the 
country), the patient’s survival status will continue to be collected until death, lost to follow-up or until 12 
months after the end of trial, even if the patient progressed according to RECIST 1.1 or started with another anti-
cancer treatment, according to patient’s informed consent

INTRODUCTION
MEDICAL BACKGROUND
1.1
The high medical need for new drugs in cancer therapy remains unchanged as still most 
patients with locally advanced or metastatic cancers will eventually die from the disease. The 
demographic development will lead to further increase in cancer incidence and the unmet need 
for therapy.
Several drugs targeting epigenetic modifiers have been successfully developed, including 
inhibitors of enzymatic “writers” such as DNA methyltransferases, and inhibitors of enzymatic 
“erasers” such as histone deacetylases. Modulation of the epigenetic regulators known as 
“readers” has recently emerged as a therapeutic strategy. One bromodomain-containing family 
is the BET family comprising BRD2, BRD3, BRD4 and BRDT. BET is important in regulating 
transcription, epigenetic memory and cell growth.
The bromodomain and extraterminal (BET) protein BRD4 recruits transcriptional regulatory 
complexes to acetylated chromatin, therefore facilitating the transcription of genes in areas of 
“open” chromatin. Pharmacological inhibition of BET proteins shows therapeutic activity in a 
variety of different pathologies, particularly in cancer models. These effects have been 
attributed to downstream target genes, whose expression is particularly sensitive to BET 
inhibition. 
BI 894999 is an inhibitor of the BET family. The preclinical efficacy and safety profile of BI 
894999 is expected to translate into a benefit for cancer patients. This study will investigate the 
safety and maximum tolerated dose of BI 894999, a BET inhibitor, administered orally to 
patients with various advanced or metastatic cancers. 
Non Clinical Pharmacology
1.2.1
Molecular potency and selectivity of BI 894999
Biochemical assays were conducted to assess the inhibitory potency of BI 894999 on the 
protein-protein interaction of acetylated lysine and the bromodomains BRD4 BD1 and BRD4 
BD2. BI 894999 inhibited the binding of bromodomain BRD4 BD1 to acetylated Histone with 
an IC50 of 5 ± 3 nM, of BRD4 BD2 to with an IC50 of 41 ± 30 nM.
In the BROMOscan selectivity screen, BI 894999 affected only bromodomains of the BET 
family (BRD2, 3, 4, T) with a constant of dissociation (Kd) of 0.49 to 1.6 nM, all the other 23 
bromodomains tested showed at least 200 fold selectivity vs. BRD4 BD1. In a broader 
biochemical screen (from the 
, 71 binding assays and 25 enzymatic assays) 
out of all the test targets, only one receptor, the benzodiazepine receptor BZD, showed 51 % 
inhibition of control specific binding at a test concentration of 1 µM.

Overall, the BET inhibitor BI 894999 shows a very good selectivity profile.
Cellular Activity
The cellular potency of BI 894999 was determined in cell proliferation assays. A panel 
consisting of >50 acute myeloid leukaemia (AML), acute lymphoblastic leukaemia (ALL), 
multiple myeloma (MM), chronic myelogenous leukaemia (CML), DLBCL (ABC and GCB-
type), and T-cell lymphoma (TCL) cell lines was tested. All cell lines except the CML line 
K562, showed an EC50 <100 nM, with most of the cell lines displaying single digit nM EC50 
values. 
For solid cancer types including SCLC, mCRPC, NC, head and neck squamous cell carcinoma, 
neuroblastoma, medulloblastoma and glioblastoma multiforme, cell line data showed 
proliferation inhibitory activity of BI 894999 (c03016865-02). Proliferation inhibitory activity 
with BI 894999 was also recently noted in CRC cell lines in vitro (new data on file, not yet 
reported).
In vivo efficacy of BI 894999
The in vivo efficacy of BI 894999 was assessed in disseminated and subcutaneously engrafted 
xenograft models.
In lymphoma studies, the subcutaneously engrafted xenograft model TMD8 is the established 
routine model for DLBCL (ABC type) in C.B-17scid mice. Treatment with BI 894999 was 
started at a tumour size of about 70 – 100 mm3. Compound was administered at daily oral 
doses of 12 mg/kg. Monotherapy of BI 894999 resulted in tumour growth inhibition (TGI) at
day 20 (sacrifice of vehicle control group due to tumour size) of 89 % compared to control. 
Rituximab was administered intra-peritoneally (i.p.) at 1 mg/kg q3 or 4 d and resulted in TGI 
of 77 %. Combination of BI 894999 and rituximab resulted in TGI of 92 %.
In a second TMD8 xenograft experiment, BI 894999 treatment was combined with ibrutinib.
In this experiment BI 894999 was dosed at 8 mg/kg (daily, per os) and ibrutinib at 12 mg/kg 
(daily, i.p.). In this experiment, BI 894999 as monotherapy was dosed below the MTD but still 
resulted in TGI of 64 %. Ibrutinib dosed at the MTD resulted in TGI of 45 %. Combination of 
both resulted in TGI of 110% with tumour regression in 6/7 animals.
Anti-tumour activity of BI 894999 was demonstrated in patient-derived xenograft (PDX) 
models for SCLC in NCR-nude or NMRI-nude mice. Mice were treated at the MTD (which is 
different depending on the mouse strain). Three of the 12 models tested were highly sensitive 
to BI 894999 with TGIs between 80% and 105% and tumour regressions, whereas the other 
nine models show TGIs between 7% and 68%. The search for a patient selection biomarker for 
SCLC is ongoing.
Anti-tumour activity of BI 894999 was also demonstrated in a prostate carcinoma xenograft 
model (MDA-PCA-2B). Mice were treated with 5 mg/kg enzalutamide once daily or with 12 
mg/kg BI 894999 once daily, with a dose reduction to 8 mg/kg on Day 12. Median tumour 
volume was compared with the median tumour volume in control mice. BI 894999 treatment 
resulted in TGI of 98%.

In the ongoing clinical study 1367.1 two responses have been documented in patients with 
solid tumour so far: a partial response in a patient with small bowel adenocarcinoma (treated 
with Schedule A) that lasted until the end of Cycle 12 and a partial response in a patient with 
oesophageal squamous cell carcinoma (treated with Schedule B) that lasted until the end of 
Cycle 6.
In summary, BI 894999 is a potent and selective BET inhibitor that showed in vitro and in vivo 
activity in hematological malignancies and solid tumours.
Pharmacokinetics and product metabolism in pre-clinical
1.2.2
The in vitro metabolism of [14C] labelled BI 894999 was investigated by the use of human liver 
microsomes and cytosol, expressed cytochrome P450 (CYP) enzymes and flavin-containing 
monooxygenases (FMO) enzymes and human hepatocytes. Based on incubations with human 
hepatocytes and with liver microsomes at low concentrations of BI 894999 (10 µM) the 
contribution to hepatic oxidative metabolism of the single enzymes was estimated to 
approximately 50 to 60% for CYP 3A4 and to approximately 40 to 50% for FMO3 
(n00240842-01)
CYP enzyme induction in human hepatocytes
The in vitro induction of CYP enzymes by BI 894999 was investigated by incubations with 
human hepatocytes (n00244406). Based on the results of these incubations, BI 894999 caused 
enzyme induction on the messenger ribonucleic acid (mRNA) level in human hepatocytes of 
CYP1A2, 2C8 and 3A4. 
According to current most conservative cut-off criteria from the FDA (P12-05791) and EMA
(P14-08681) Drug-drug interaction guidelines, BI 894999 is likely a CYP inducer if Cmax total 
exceeds 0.83 nM (CYP3A4), 0.14 nM (CYP2C8) or 1.38 nM (CYP1A2).
Estimated efficacious human dose
A human clearance of 7.9 mL/min/kg was predicted based on simple allometry. A human 
volume of distribution at steady state of 4.9 L/kg was predicted based on mean of animal data. 
This resulted in a predicted human disposition mean residence time and effective half-life of 
10.5 h and 7 h, respectively.
The human therapeutic dose is predicted based on effective plasma concentration in the mouse 
xenograft model. Assuming similar potency of BI 894999 in humans and the mouse model, and 
taking into account similar protein binding between both species; this translates into a 
therapeutic dose of 45 mg (free base) once daily to achieve an anticipated effective plasma 
concentration above 35 nM for 6h in humans (n00240650-01).
Toxicology
1.2.3
The toxicity profile for BI 894999 has been assessed in a 2-week exploratory study in rats, a 2-
week dose range-finding study in dogs and 4-week toxicity studies in both species. In rats, a no 
observed adverse effect level (NOAEL) was achieved with 0.075 mg/kg. In dogs, there was no 
free dose down to a level of 0.0125 mg/kg. The nonclinical safety package, which also includes

safety pharmacology and immuno-toxicology endpoints, supports the administration of BI 
894999 to humans. 
The primary target organs of toxicities were the lymphoid and hematopoietic system (decreases 
in white blood cell count, monocytes, lymphocytes and platelet counts), the digestive tract (oral 
mucositis, degeneration, erosion and ulcers), the liver (hepatocellular atrophy, changes in liver 
enzymes), the testes (germ cell degeneration and loss) and the kidneys. Inhibition of the BET 
proteins with BI 894999 showed a rather steep dose-adverse effect curve and a delayed onset of 
adverse effects.
The assessment of the photochemical properties of BI 894999 indicates a potential risk of 
photo-toxicity. Appropriate protective measures must be taken during outpatient trials.
No cardio-toxicity risk is expected based on pre-clinical toxicity data.
A safe starting dose was estimated in accordance with the General Guide for Starting Dose 
Selection for a Cytotoxic Agent in Cancer Patients (FDA/CDER) and based on the data of 4-
week toxicity studies in rats and dogs. Using the conversion factor of 6, the high dose of the rat 
study of 0.5 mg/kg (severely toxic dose for 10 % of rodents, STD10) was transformed to 3 
mg/m². The high dose of the dog study (non-severely toxic dose) was converted from 0.05 
mg/kg to 1 mg/m² using the conversion factor of 20. The dog was considered to be the most 
sensitive species. Following the recommended decision tree 1/6 of 1 mg/m² = 0.17 mg/m² is the 
safe starting dose for cancer patients, which corresponds to 0.0045 mg/kg (using the conversion 
factor of 37). Based on a patient body weight of 70 kg, the calculated starting dose would be 
0.31 mg/patient/day.  However, due to the availability of tablet dose strengths, the starting dose 
in this first-in-human Phase I trial will actually be 0.2 mg per patient per day for the very first 
patient included in the trial, in Schedule A.
In summary, based on preclinical safety pharmacology studies, side effects of BI 894999 in 
humans may include symptoms related to the lymphoid and hematopoietic system (decreases in 
white blood cell count, monocytes, lymphocytes and platelet counts), the digestive tract (oral 
mucositis, diarrhoea,), liver (liver enzymes), kidneys and blood glucose levels. Patients will 
therefore be monitored for these side effects. Based on current knowledge of BET inhibitors 
and non-clinical data obtained for BI 894999, effects on testes are anticipated.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
RATIONALE FOR PERFORMING THE TRIAL
2.1
Most patients with locally advanced or metastatic tumours will succumb to their disease. Thus, 
there is a substantial need for novel therapeutic strategies to improve the outcome for patients 
with advanced or metastatic malignancies. This is particularly true for patients with NC which 
is a very aggressive malignancy for which no standard of care has been established. As this rare 
disease is observed in adolescents and young adults (R18-2451), for this indication, the trial 
will allow inclusion of minor patients aged 15 years or more. 
Recently, preliminary data of the Phase I trials of other BET inhibitors have been reported and 
promising results were observed in patients with lymphoma particularly in DLBCL. In the 
Phase I trial of CPI-0610 in patients with relapsed/refractory lymphoma, objective responses 
were observed in 4 patients with lymphoma including 3 patients with DLBCL (R16-1012). In 
the Phase I trial of OTX015 in patients with advanced haematological malignancies, 3 patients 
in the DLBCL cohort experienced an objective response (R15-1329).
BI 894999 is a potent inhibitor of BET bromodomain and as such prevents the transcription of 
relevant, as yet unidentified genes and thereby blocks proliferation and induces apoptosis in 
cancer cells (data on file).
Based on the preclinical studies 
, the observed anti-tumour 
activity in preclinical studies of BI 894999 and in clinical studies of other BET inhibitors and 
safety profile of BI 894999, clinical testing of BI 894999 is warranted. The present study is the 
first-in-human study to determine the safety profile and the MTD of BI 894999 in cancer 
patients for whom no standard treatment options exist.
TRIAL OBJECTIVES
2.2
The main objective of the dose escalation part of the trial is to determine the MTD using a 
continuous dosing Schedule A , the MTD using an intermittent Schedule B (2 weeks on, one 
week off in 3-week cycles) and the MTD using an intermittent Schedule C (a loading dose on 
first day followed by a maintenance dose for the next six days and followed by one week off 
treatment, repeated every two weeks in 4-week cycles) in patients with solid tumours and 
provide safety data in terms of drug-related adverse events (AEs) for the recommendation of 
the dose and schedule of treatment for the expansion Phase Ib of this trial (between Schedules 
A and B) and for further trials in the development of BI 894999 (between Schedules B and C) 
(see Section 5.2). Once the MTD has been determined for both schedules A and B in patients 
with solid tumours, the MTD was determined as well in patients with diffuse large B-cell 
lymphoma (DLBCL), using the DMC recommended schedule for solid tumours which was 
Schedule B. The MTD will also be determined in patients with DLBCL using the Schedule C 
in order to recommend the dose and schedule for further trials in DLBCL in the development 
of BI 894999 (see Section 1.3).

Secondary 
 objectives are the determination of the pharmacokinetic (PK) profile of 
BI 894999 after single and multiple dose (see Section 5.4),
 
) and assessment of anti-tumour activity (see Section 
5.2). 
In the expansion phase, the main objective lies upon collection of further safety information at 
the dose recommended by the data monitoring committee (DMC) for Phase Ib (2.5 mg in 
Schedule B was recommended based on Schedule A and B data) and with the Schedule 
(between B and C) and dose recommended by the DMC for the Phase Ib NC cohort. The 
secondary 
 objectives will be to increase the number of patients with solid tumours 
and with evaluable PK results at the recommended Phase Ib dose for Schedule B in the four 
types of tumours and for Schedule C in the NC cohort, and the same as in the dose escalation 
part for the assessment of anti-tumour activity.
 
 
 
BENEFIT - RISK ASSESSMENT
2.3
BI 894999 inhibits tumour growth and induces tumour regression in pre-clinical models. Based 
on pre-clinical results, the inhibitory effects on BET bromodomain may translate into a clinical 
benefit in cancer patients. Although the starting dose is not expected to be efficacious, the dose 
escalation scheme guided by a Bayesian two-parameter logistic regression model (BLRM) (de-
escalation of dose is possible in case of insufficient tolerability of a dose level) is designed to 
escalate the dose quickly into a dose range where efficacy may be seen while still minimizing 
the risk of undue tolerability issues. 
None of the doses tested in dogs were free of adverse effects. Based on these studies, the most 
relevant side effect of BI 894999 is expected to be a transient inhibition of proliferation of 
normal dividing cells in mucosal tissue and bone marrow. Inhibition of mucosal proliferation 
may lead to gastro-intestinal symptoms such as nausea, diarrhoea, mucositis, and/or abdominal 
pain. Patients in this study will be closely monitored for these side effects and supportive 
treatment will be given by the investigators if necessary. The side effects on bone marrow cells 
may lead to a temporary decrease of blood cells and platelets. These side effects are frequently 
seen in cancer patients treated with conventional cytotoxics or targeted therapies and can 
readily be monitored with regular blood tests. Supportive treatment for some of these effects is 
available. 
In addition to these effects, some changes in laboratory values were observed such as an 
increased level of glucose and a decrease of phosphate.
Specific procedures have been implemented to early detect these and other potential side 
effects and to allow their immediate supportive treatment and follow up. The sites will be 
experienced Phase I oncology sites with the appropriate clinical personnel available and access 
to emergency care units in case of need. The patients will also remain at the clinical site, under 
surveillance, for the first 24 hours after the very first administration.

Preclinical studies with BI 894999 have also shown degeneration of germ cells in testes of 
dogs. This is the reason why male patients having a partner of childbearing potential must use 
condoms and ensure their partner is using a highly effective method of birth control during the 
trial and for at least three months after the end of the trial.
In the study of the effect on hERG-mediated potassium current, BI 894999 did not show any in 
vitro signal for a pro-arrhythmic risk based on prolongation of ventricular repolarisation. This 
was confirmed in studies in dogs and rats which did not show a negative effect on myocardial 
contractility or a pro-arrhythmic effect (c03016865-02). However, to confirm this absence of 
pro-arrhythmic effect in humans, in addition to normal clinical monitoring of the 
cardiovascular functions by measurement of pulse and blood pressure (BP), regular 
electrocardiogram (ECG) records will be performed for further characterisation and will be 
centrally analysed by a core lab. 
On 04 Oct 2016, the sponsor decided to put a temporary hold on further recruitment of patients 
in trial 1367.1. The measure was taken since review of patient data revealed some patients with 
increased troponin levels. A thorough review by cardiologists was initiated with regards to 
troponin levels, ECG, and clinical summaries of all enrolled patients. Evidence supporting a 
causal association between the increased laboratory troponin values and the administration of 
the trial medication could not be established. There were no corresponding clinically 
significant findings based on the reviewed ECGs and the clinical summaries of enrolled 
patients. The external review concluded that the cause of troponin elevation may be 
multifactorial in the trial patient population. In conclusion, the findings were considered to not 
preclude further clinical development. Consequently, patient recruitment was re-started.
Patients on study will be closely monitored and will undergo regular controls of CK and 
troponin highly sensitive (see Section 5.3.3), together with ECG evaluation.
Furthermore, every patient will undergo a mandatory echocardiography or multiple gated 
acquisition (MUGA) scan for left ventricular ejection fraction (LVEF) determination during 
screening and then at the end of Cycle 2 and at the end of treatment (if the patient’s condition 
at the time of end of treatment permits so). Cardiologic assessments (CK, troponin hs (T or I), 
ECG, echocardiography and any other examination as judged necessary) should be prompted 
by the investigator upon clinical indication at any time (see Section 4.1.4.3.1).
Other treatment-emergent AEs which were most frequently observed in this Phase I trial so far 
include: fatigue, thrombocytopenia, decreased appetite, dysgeusia, increased CK, diarrhoea, 
nausea and stomatitis. Neutropenia was also observed but it was less frequent than the above 
AEs.
Thrombocytopenia 
is 
considered 
an 
expected 
AE 
associated 
with 
BI 
894999. 
Thrombocytopenia (especially CTCAE grade 4) could be associated with an increased risk of 
bleeding and is therefore considered medically important.
Asymptomatic grade 1–2 factor VII decrease was noted in some patients treated with another 
BETi, OTX-015 in a Phase I study conducted in patients with lymphoma or multiple myeloma 
(R15-1329). Prolonged coagulation times have also been reported as treatment related adverse 
events in a Phase I study with the BET inhibitor INCB057643 (R18-1831) and in a Phase I

Study with the BET inhibitor GSK525762 (R18-2390). Monitoring of coagulation parameters 
in the 1367.1 study revealed that some patients present with mild prolongation of prothrombin 
time (PT) and increase in international normalized ratio (INR) on Day 14 of Cycle 1. 
Coagulation parameters will continue to be monitored during the study and will be evaluated 
before the performance of tumour biopsies. Tumour biopsies will only be performed if the 
platelet count is above 50 000/mm3 without the support of transfusion and coagulation 
parameters (aPTT, PT in sec and INR) are within normal limits on the day of the biopsy. It is 
possible that prolonged PT will occur concurrently with thrombocytopenia in a patient being 
treated with BI 894999. The coexistence of thrombocytopenia and coagulopathy could 
potentially increase the risk of bleeding events. In order to reduce the risk of bleeding events in 
patients with severe thrombocytopenia and prolonged coagulation times, mandatory 
prophylactic platelet transfusions need to be administered to all patients who present with a 
platelet count below 20 000/mm3. 
Based upon a non-clinical safety study in vitro, a potential risk of photo-toxicity /
photosensitization in vivo could not be excluded. Therefore, adequate precautions must be 
taken during treatment with BI 894999 (avoidance of prolonged ultraviolet (UV) exposure, use 
of broad spectrum sunscreen).
Although rare, a potential for drug-induced liver injury is under constant surveillance by 
sponsors and regulators. Therefore, this study requires timely detection, evaluation, and follow-
up of laboratory alterations of selected liver laboratory parameters to ensure patients’ safety 
(see also Section 5.3.6.1).
Based on its mode of action, BI 894999 is not expected to have a relevant impact on 
susceptibility to or on the course of an infection, however, in DLBCL patients, the 
susceptibility to a COVID-19 infection may be increased.
Patients in this trial may have an increased risk for severe illness from COVID-19. In case of 
an increased risk of COVID-19 infection, physical visits to the sites should be avoided where 
the investigator judges that this is the safest course of action. They should be replaced with 
remote visits, procedures and lab testing will be done remotely as far as possible (see Sections
4.1.4.2 and 6.1). These measures ensure the safety of the patients throughout the trial, maintain 
the integrity of the trial and will not affect the benefit-risk of BI 894999.
In case of a confirmed infection, trial treatment will be interrupted immediately and appropriate 
measures for monitoring, treatment and quarantine will be implemented. The patient may 
resume treatment following recovery from a COVID-19 infection if the patient is expected to 
derive clinical benefit, as agreed between the Investigator and Sponsor.
Trial procedures such as blood sampling, imaging with e.g. contrast media, tumour biopsies,
are part of standard of care in these advanced cancer patients but are performed at a higher 
frequency during this trial. The additional blood samplings increase the risk for anaemia which 
can be corrected by appropriate transfusion if necessary. The imaging performed every other 
cycle can bring additional long term radiation burden but these advanced patients are not 
expected to remain for very long periods in the study and it is the only way to detect early 
progression or early response to avoid unnecessary further treatment or a premature stop while 
the trial treatment would be beneficial to the patient.

There is an added risk for pain, swelling, bleeding for those patients who will undergo tumour 
biopsies at screening and during the trial, under treatment. For this reason, biopsies will only be 
performed when deemed safe by the investigator, if the platelet count is at least 
50 000/mm3 without the support of transfusion and if coagulation parameters are within normal 
limits on the day of the biopsy.
Patients with advanced solid tumours, and relapsed/refractory DLBCL who have limited or no 
established treatment options may theoretically benefit from the treatment with BI 894999 
(tumour regression, disease stabilisation or improvement of tumour-related symptoms). The 
potential benefit of therapy with BI 894999 is expected to outweigh the treatment and 
procedures related risks.
For the NUT carcinoma patients of Phase Ib, enrolment of adolescents ≥15 years of age will be 
allowed. Indeed, the dose, safety and metabolism in adolescents of ≥15 years are expected to 
be similar to adults because body size is expected to be close to adults and organ maturation is 
expected to be completed. However, to confirm the hypothesis that safety is similar in 
adolescents and adults, a mandatory DMC meeting will take place after the first and after the 
second adolescent patient completes Cycle 1 to assess whether the adult dose is tolerable in 
adolescents. In this population the benefit is expected to outweigh the risks because there is no 
standard treatment available and BI 894999 is specifically targeting the NUT fusion that is 
characteristic for the disease.

Figure 3.1: 2: Trial Design for DLBCL
The trial is designed as an open label, uncontrolled study and had a dose escalation Phase Ia to 
determine the MTD in solid tumours in two different schedules, Schedule A with continuous 
dosing once daily in 3-week cycles and Schedule B with once daily dosing for 2 weeks 
followed by one week off treatment in 3-week cycles with an extended cohort at MTD in the 
selected schedule B) as decided by the DMC in December 2017, based on the safety, 
pharmacokinetic and pharmacodynamics data available from all patients treated by that stage. 
This is then followed by an expansion Phase Ib in selected solid tumour indications with the 
chosen dose (2.5 mg) and schedule (Schedule B) as decided by the DMC in April 2018. The 
DMC also confirmed the decision on which types of tumours to include in this expansion phase
(DMC meeting of September 2017). During the Phase Ia, once the MTD has been determined 
in both Schedules A and B in solid tumours, testing of the chosen Schedule by the DMC (i.e.
Schedule B) in patients with DLBCL commenced to determine the MTD of BI 894999 with 
Schedule B in patients with DLBCL. The starting dose was one dose lower than the MTD dose 
in patients with solid tumours.
The dose escalation part using Schedule B in patients with solid tumours happened in parallel 
with the dose escalation part of Schedule A and started at the highest dose level tested in 
Schedule A in solid tumours considered to be safe by the DMC.

Further to the results from modelling of toxicity observed on thrombocytes and results of PK 
and pharmacodynamics, an additional dose escalation was performed with a Schedule C with 
the aim of finding an optimal dosing schedule (loading dose on Day 1 followed by 6 days of 
maintenance dose and one week off treatment, repeated every 2 weeks in 4-week cycles) in 
parallel with the dose finding part in DLBCL patients with Schedule B. The starting 
maintenance dose for Schedule C was the dose selected by the DMC for Schedule B in Phase 
Ib which is 2.5 mg with a double loading dose of 5 mg. In parallel, after approval of protocol 
version 11.0, the MTD will also be determined for Schedule C in patients with DLBCL, 
starting at one dose tier below the one used in solid tumours to start with Schedule C, both for 
the loading dose and for the maintenance dose, meaning with a loading dose of 4 mg and a 
maintenance dose of 2 mg. Once the MTD with both Schedules B and C in DLBCL patients 
have been determined, the DLBCL cohort will be extended at the MTD level of the schedule 
selected by the DMC to have the best toxicity profile, to include in total for the MTD cohort 
from 12 to 14 patients.
The dose escalation will be guided by a BLRM (see the different scenarios in Appendix 10.3) 
(de-escalation of dose is possible in case of insufficient tolerability of a dose level) (R04-0569),
and will be determined by the DMC which will evaluate and decide on the dose to be 
administered for the next cohort. An escalation with overdose control design will increase the 
chance of treating patients at efficacious doses while reducing the risk of overdosing.
Dose escalation Phase Ia of Schedule A in patients with solid tumour:
One patient was treated per dose cohort until a first drug-related AE of CTCAE grade ≥ 2 
occurred during the first treatment cycle (see description in Section 4.1.3.1). Thus, the next 
patient could only start the treatment at the next dose level once it was confirmed that the 
previous patient from the lower dose level did not experience a drug-related CTCAE grade ≥ 2 
AE during Cycle 1. 
In case no patient from the first cohort experienced a CTCAE ≥ grade 2 drug-related AE during 
Cycle 1, the dose could be increased from 0.2 mg to 1 mg in the second cohort. In case no 
patient from the second cohort experienced a CTCAE ≥ grade 2 drug-related AE during Cycle 
1, the dose could be increased from 1 mg to 5 mg in the third cohort. Afterwards, increments 
have followed the Bayesian model as explained in Appendix 10.3.
If a patient, in a single patient cohort, experienced a CTCAE grade ≥ 2 drug-related AE during 
Cycle 1 at any dose level, additional patients were to be entered in the same cohort and at least 
2 patients evaluable for dose limiting toxicity (DLT) in Cycle 1 were required per cohort, from 
that cohort onwards.
The second patient of a same cohort could only start his treatment after the first patient of the 
cohort had been observed for a period of 7 days of treatment and a second and a third patient 
could then be started at the same time.
In case only 2 patients were evaluable and neither had experienced a dose-limiting toxicity 
within the first cycle (21 days), then dose-escalation could occur based on these 2 patients. But, 
if one of these 2 patients experienced a DLT in the first cycle (21 days), a third patient had to 
be enrolled at the same dose level and be evaluable for DLT in the first cycle.

After all patients in a cohort had either experienced a DLT or had been observed for at least 
one cycle without a DLT (until Day 22 of Cycle 1), the BLRM was updated with the newly 
accumulated data. The overdose risk was then calculated for each dose, and escalation was
permitted to all doses, which fulfilled the Escalation with Overdose Control (EWOC) criterion 
and dose escalation rules according to Section 4.1.3. Decision on next step (dose escalation, de-
escalation or cohort extension) was made by the DMC, based on the collected safety data as 
well as other data (e.g., PK / pharmacodynamics data) when available.
If DLTs were observed in the first two consecutive patients of a previously untested dose level, 
subsequent enrolment to that cohort was stopped. The BLRM was re-run to confirm that the 
dose-level still fulfilled the EWOC criterion. The DMC decided whether the next patients were 
to be enrolled at the same dose level, or if they were to be enrolled to a lower dose level. Figure 
3.1: 3 shows how the decision of dose escalation was made.
Figure 3.1: 3: Escalation Decision – Combination of clinical and statistical expertise
Dose escalation Phase Ia and expansion Phase Ib of Schedule B in patients with solid tumour:
The starting dose for the dose escalation Phase Ia of Schedule B in patients with solid tumour 
was the highest dose level tested in Schedule A in solid tumours considered to be safe by the 
DMC. Dose escalation and de-escalation was guided by the BLRM from the beginning, i.e., no 
single patient cohorts were foreseen.
The DMC could recommend stopping the dose escalation phase after the criterion for MTD 
was fulfilled.
Once the MTD had been determined for both Schedules A and B in patients with solid 
tumours, the DMC made a recommendation on the recommended Schedule based on safety, 
PK and pharmacodynamics data available from all patients treated at this stage, and the MTD 
cohort of the chosen schedule which was Schedule B was further extended to enrol a total of 12 
patients with solid tumour at this dose level of 2.5 mg.

At doses deemed close to the MTD in Schedule A in patients with solid tumours (decision was
made by DMC on which cohort(s) the 
 study would happen) and at the MTD dose in 
patients with solid tumours, a minimum of 12 patients and up to 20 patients in total with solid 
tumours in either Schedule A or B participated to the determination of 
 on 
pharmacokinetics (see Section 10.2.2).
Once the MTD was determined for both Schedules A and B in solid tumours and the choice of 
the most appropriate Schedule was made (Schedule B), newly recruited patients in the 
extension of the MTD cohort could undergo optional tumour biopsies at screening and at 
steady state in Cycle 1.
In Phase Ib, the tumour biopsies at baseline and at steady state (between Day 8 and Day 11) 
under treatment in Cycle 1 were mandatory. The baseline biopsy could be replaced by sending 
of tumour archival tissue from the latest relapse if not older than 6 months. A 2-3 mL EDTA 
blood DNA sample was mandatory, once, at any time, for all patients undergoing a tumour 
biopsy or for whom archival tumour tissue is sent. 
For the biopsy to be allowed, platelet count and coagulation have to be checked prior to each 
biopsy and have to be adequate, meaning platelets of at least 50 000/mm 3 without the support 
of transfusion and coagulation parameters within normal limits.
Should the biopsy under study treatment, between Day 8 and Day 11 of Cycle 1 not be feasible 
in 5 out of the first 20 patients of Phase Ib in solid tumours because of abnormal coagulation 
parameters and/or a platelet count below 50 000/mm3, the timing of biopsy at steady state 
would be moved ahead, between Day 3 and Day 8 for the next patients.
The tumour biopsies in Phase Ib were however not requested for mCRPC patients with only 
bone lesions and for patients with therapeutic INR because of treatment with a vitamin K 
antagonist or a novel oral anticoagulant. Biopsies remained optional for NC patients. 
The on treatment biopsy could remain optional if no easily accessible lesions were available.
Dose escalation Phase Ia with Schedule C in patients with solid tumours:
The starting dose for the dose escalation Phase Ia of Schedule C in patients with solid tumour 
was the MTD determined for Schedule B, which is 2.5 mg with a loading dose of 5 mg. So the 
patients took 5 mg on Day 1 followed by 2.5 mg from Day 2 till Day 7, t hen a week off 
treatment and again a loading dose of 5 mg on Day 15 followed by a maintenance dose of 2.5 
mg from Day 16 till Day 21, then a week off treatment in 4-week cycles. Dose escalation and 
de-escalation for subsequent cohorts was guided by the BLRM for this schedule.
The DMC could recommend stopping the dose escalation phase after the criterion for MTD 
was fulfilled (see Section 7.1).
Once the MTD has been determined for Schedule C in patients with solid tumours, the MTD 
cohort will be further extended to enrol a total of 12 patients with solid tumour at this dose 
level. 
Dose escalation Phase Ia of selected schedule (B) in patients with DLBCL:
Once the MTD was determined for both Schedules A and B in solid tumours and the choice of 
the most appropriate Schedule was made (Schedule B), the dose escalation started with this 
Schedule (B) in patients with DLBCL.

The starting dose for the dose escalation in patients with DLBCL (2 mg) was one dose level 
below the MTD of the selected schedule (B) in patients with solid tumour and the dose 
escalation and de-escalation was guided by the BLRM from the beginning, i.e., no single 
patient cohorts were foreseen. 
Dose escalation Phase Ia of Schedule C in patients with DLBCL:
After MTD determination for Schedule B in DLBCL patients, a dose escalation was started 
with Schedule C in patients with DLBCL.
The doses to use in the first cohort for the dose escalation Phase Ia of Schedule C in patients 
with DLBCL were, both for the loading and the maintenance dose, one dose tier below the 
doses used for the first cohort with Schedule C in patients with solid tumours. So the patients 
take 4 mg on Day 1 followed by 2 mg from Day 2 till Day 7, then a week off treatment and 
again a loading dose of 4 mg on Day 15 followed by a maintenance dose of 2 mg from Day 16 
till Day 21, then a week off treatment in 4-week cycles. Dose escalation and de-escalation for 
subsequent cohorts will be guided by the BLRM for this schedule.
Once the MTD will be determined in both Schedules B and C in patients with DLBCL, the 
DMC will make a recommendation on the schedule to be selected between B and C to further 
expand the MTD cohort in DLBCL in 6 to 8 additional patients.
In addition, patients (with solid tumour or DLBCL) who are responding to treatment or who 
are benefiting from treatment, may undergo optional fresh tumour biopsy (platelet count and 
coagulation must be checked prior to each biopsy and must be adequate, see above) and may 
provide optional consent for analysis of their archival tumour sample. In these patients who 
provide consent for a fresh tumour biopsy and/or analysis of their archival tumour sample, a 2-
3 mL EDTA blood DNA sample is mandatory.
The observation period for DLT is 21 days of the first cycle only (to be assessed at Day 22) ) in 
Schedules A and B. For Schedule C, the observation period for DLT is 28 days of the first 
cycle (to be assessed on Day 29).
However, confirmation of the recommended dose for the Phase Ib expansion part was made by 
the DMC, based on all available safety, PK and pharmacodynamics data at all treatment cycles, 
at the time of decision in April 2017. The DMC in addition made recommendation on the types
of solid tumours that were chosen for the Phase Ib part, based on anti-tumour signals that 
appeared from data collected during the escalation part, together with additional pre-clinical 
data available at the time of the end of the escalation phase.
The expansion Phase Ib with Schedule B recruited a minimum of 9 evaluable patients (for PK 
and response by RECIST at the end of Cycle 2 or by bone scan and PSA at the end of Cycle 4 
in mCRPC patients with non-measurable disease by RECIST 1.1) and a maximum of 20 
evaluable patients with measurable (or non-measurable per RECIST 1.1 for mCRPC patients) 
and progressive disease, per type of tumours selected by the DMC: SCLC, mCRPC, CRC and 
NC. For the NC cohort, since this is a rare disease, the number of patients was not pre-defined 
but tended to include up to a maximum of 40 patients. 
Once the MTD for Schedule C was determined in Phase Ia in patients with solid tumours, the 
DMC recommended the best schedule between B or C to further recruit patients in the NC

cohort. As Schedule C was selected, a Schedule C NC cohort was opened to recruitment for up 
to a maximum of 40 patients while the NC cohort with Schedule B was closed to recruitment.
This expansion phase will further evaluate the safety including re-evaluation of the 
recommended Phase II dose and the selected schedule (B or C), efficacy, pharmacokinetic and 
biomarker profile of BI 894999 in patients with the chosen specific types of tumours. The 
DMC will have regular meetings (at least once every 3 months) to evaluate the safety of the 
patients in Phase Ib and confirm the safety of the selected dose in the specific patients’ 
population. In addition, the DMC will have meetings after the first and after the second 
adolescent patient with NC finishes the first cycle to assess whether the adult dose is tolerable 
in adolescents.
Patients will be kept at the institution, based on convenience for the patient and the 
investigator’s decision of patient’s need for safety surveillance, for the first administration of 
study medication, for a period of 24h from C1D1 until C1D2 (at investigator’s discretion, can
be limited to a period of 4h on Day 1 in DLBCL and NC patients recruited after approval of 
protocol version 12.0) and for 48h in the 
 cohort until drug administration of 
C1Day3. Patients will be kept at the institution for a period of 24h, from C1D14 until last PK 
sample of Day 15 for Schedules A and B (24h post-dose of Day 14 dose in Schedule A or 32h 
post-dose of Day 14 in Schedule B), based on convenience for the patient and investigator’s 
decision. For Schedule C, this will be on C1D21 until last PK sample of Day 22. However, all 
other visits from first cycle and all visits from subsequent cycles will be performed in an 
outpatient setting except if medically or operationally justified, at the discretion of the 
investigator. During treatment, the investigator will determine the safety parameters, record the 
AEs and perform additional investigations as outlined in the Flow Chart.
A clinical disease assessment will be performed after every treatment cycle and a tumour 
response assessment by imaging every other cycle for all patients with solid tumours. The type 
of imaging (computed tomography (CT) scan or magnetic resonance imaging (MRI), with or 
without contrast media) is left to the decision of the investigator but must be the same all over 
the trial period and must allow for evaluation according to RECIST 1.1. Assessment of 
response will be performed at the investigator’s site and will be sufficient for the decision 
whether the patient will continue therapy according to the criteria specified in Section 4.1.4. In 
mCRPC patients without a measurable disease via RECIST 1.1, the response assessment had to
be performed on bone scan every 12 weeks coupled with PSA level at the same time-point as 
imaging. In patients with DLBCL, the response assessment will be performed by imaging via 
FDG-PET/CT scan after end of Cycle 2, of Cycle 4 and every four cycles thereafter.
Patients with a clinical benefit after a cycle of BI 894999 (absence of disease progression
(except for NC patients for whom the investigator judges that there is clinical benefit and for 
whom no other treatment option is available) and good treatment tolerance) and who have 
recovered from any clinically or haematologically relevant drug-related AE of grade 3 or 4 (to 
grade 1 or less or to baseline grade, except grade 2 peripheral sensory neuropathy as well as 
anaemia, lymphopenia), as judged by the investigator, are eligible for a further treatment cycle. 
Intra-patient dose escalation will not be allowed as well as switch from one schedule to 
another. Patients included in the escalation phase are not eligible to enter the expansion phase.

Patients experiencing DLT or any drug related significant AE necessitating a dose reduction 
according to investigator’s judgement are eligible for further treatment cycles with BI 894999
at one dose tier below in the same schedule, as soon as recovery from drug related toxicities 
allows further treatment. For Schedule C, this means a decrease of the loading dose in steps of 
1 mg and of the maintenance dose in steps of 0.5 (e. g., for the first cohort, the loading dose 
would be reduced from 5 mg to 4 mg, from 4 mg to 3 mg, from 3 mg to 2 mg while the 
maintenance dose would be decreased from 2.5 mg to 2 mg, from 2 mg to 1.5 mg, from 1.5 mg 
to 1 mg). Once a dose reduction occurred, the patient must continue at the reduced dose and 
may not be re-escalated later on. A patient may decrease the dose each time as necessary 
during the trial to the next lower dose level tested (or as explained above for Schedule C)
because of DLT occurrence but not below a dose of 1 mg (maintenance dose in Schedule C).
Patients eligible for a further (repeat) treatment cycle will not start before 22 days after the start 
of the previous cycle for Schedules A and B, not before 29 days after the start of previous cycle 
for Schedule C. 
If a patient has to be discontinued from the trial treatment, the end of treatment (EOT) visit 
with all necessary assessments as described in Sections 6.2.3 and 10.5.3 must be performed as 
soon as possible once the decision is taken. Follow-up visits will be performed after the EOT 
visit until progression of disease, death, treatment with any other anti-tumour therapy, lost to 
follow-up (every attempt must be made to avoid this option, e.g. by phone contact with the 
patient or relatives) or until the end of the trial. For the NC patients, the vital status will
continue to be collected until death, loss to follow-up, withdrawal of consent to be further 
followed-up or until 12 months after the end of the whole trial, to be able to determine the 
overall survival in this population, according to their informed consent. Ongoing AEs must also 
be followed up until resolution or until the investigator deems it is no longer necessary to 
follow them up. The first follow-up visit which is the end of residual effect period (EOR) visit 
must be performed 30 days (+7 days) after the EOT and subsequent follow-ups, if applicable, 
at 12 weeks intervals or earlier if appropriate. Follow-up visits may also be performed by 
telephone interview in case the patient is unable to visit the investigator.
The trial will end when the last ongoing patient has completed the EOT visit and the EOR visit.
Administrative structure of the trial
3.1.1
Boehringer Ingelheim (BI) is the sponsor of this trial and it was planned to start the trial in 2 
centres specialized in the treatment of advanced cancers and experienced in Phase I studies in 
oncology, in one country. More centres from the same country and from additional countries 
were initiated. However, Schedule C escalation part in patients with solid tumours only 
happens in the participating sites in Belgium.
A Coordinating Investigator was nominated by BI from one of the trial participating 
investigators and is responsible to coordinate investigators at different centres participating in 
this multicentre trial. Tasks and responsibilities, including the final signature of the clinical trial 
report (CTR), are defined in a contract. Relevant documentation on the participating (Principal) 
Investigators and other important participants, including their curricula vitae, are filed in the 
trial master file (TMF).

(e.g. PK data) and confirm dose escalation steps in the three Schedules A, B and C in patients 
with solid tumours. Once the MTD was determined for both Schedules A and B in solid 
tumours, the DMC recommended a Schedule to use in the MTD extension cohort in patients 
with solid tumours as well as for determination of MTD in patients with DLBCL. Schedule B 
was selected. After decision in protocol version 11.0 to also test Schedule C for MTD 
determination in DLBCL patients, once MTD will be determined for both Schedules B and C 
in this patient population, the DMC will recommend a Schedule to use in the MTD extension 
cohort in patients with DLBCL.
The DMC also evaluated all available data to confirm the proceeding to Phase Ib expansion, 
the recommended Phase Ib dose (2.5 mg) and schedule (Schedule B) in patients with solid 
tumours as well as the decision for the types of tumours in this expansion Phase Ib. 
Once the MTD was determined for Schedule C in solid tumours patients, the DMC made the
recommendation for continuing the recruitment in the NC cohort of Phase Ib with Schedule C. 
The recruitment to the NC cohort with Schedule B was closed.
Members of this DMC are the Principal Investigators (PIs) of the participating trial sites, the 
Team Member Medicine (TMM), the TCM, the trial statistician (TSTAT), the Trial 
Pharmacokineticist (TCPK) and the Translational Medicine Expert (TME) or their delegates. 
The extended membership is described in the DMC charter.
During DMC meetings, the information on the overdose risk are presented by the BI trial team. 
Additional information, such as lower grade AEs, PK (when available), pharmacodynamics
biomarkers (when available), individual patient profiles and other relevant information such as 
the outcome events of progressive disease not reported as (S)AEs are also presented. Based on 
this information, the members of the DMC reach a joint decision on the next dose level to be 
investigated. This dose level may be above, below or identical to the currently investigated 
dose level. The DMC also recommends the size for the next cohort (minimum one, maximum 
six patients per cohort, until MTD where up to 12 patients will be included, for the chosen 
Schedule between A and B, which was Schedule B, for Schedule C in patients with solid 
tumours and in patients with DLBCL). The final decision on the next cohort size is however 
made by a mutual decision between the TMM and the Coordinating Investigator.

Minimum needed data for dose escalation decision is detailed in a DMC charter that is filed in 
the TMF. Minutes of the DMC meetings and recommendations are documented and archived 
by the TCM in the TMF.
During Phase Ib, the DMC will also regularly review the safety and efficacy data of patients 
entered in the specific cohorts. In the NC cohort, the DMC will specifically evaluate safety data 
of the first cycle in the first and second adolescent included in the cohort to assess whether the 
adult dose is tolerable in adolescents. 
Once the primary endpoint of the Phase Ia was reached in patients with solid tumours for both 
Schedules A and B and the MTD was confirmed in the extension cohort with the most 
appropriate schedule in these patients (Schedule B was selected), the Phase Ib started and a 
Phase Ia safety analysis report was prepared based on the Phase Ia data for Schedules A and B 
in patients with solid tumours. A summary of safety and efficacy endpoints and determination 
of the recommended Phase Ib dose and schedule was included in the Phase Ia safety analysis 
report. The Phase Ia report is made available for all investigators who participate in the Phase 
Ib. This report is also sent to regulatory agencies. It will be the basis, together with the 
Schedule C results in patients with solid tumours, for publication of Phase Ia results of patients 
with solid tumours by the Coordinating Investigator.
The safety laboratory investigations are performed at the investigator’s site (see 5.3.3), as well 
as ECGs. In addition, all ECGs are analysed by a central laboratory (in case of clinically 
relevant abnormalities, the investigator will be notified by email and/or fax by the central 
laboratory).
Analyses of pharmacokinetics samples are performed by BI. 
 
 
Further details on CROs for samples handling, shipments and analyses are given in the 
ISF/laboratory manual.
The trial drug is directly forwarded by Boehringer Ingelheim or via a distributing CRO to the 
investigator’s pharmacy where it will be stored according to storing requirements as described 
in the pharmacy manual. The pharmacist (or investigator directly to the patient, where legally 
authorised) will deliver the necessary amount for an individual patient to the investigator upon 
his/her request, according to the procedure described in the pharmacy manual or the local site 
procedure.
Data Management and Statistical Evaluation is done by BI according to BI SOPs.
Tasks and functions assigned in order to organise, manage, and evaluate the trial are defined 
according to BI SOPs. A list of responsible persons and relevant local information can be 
found in the ISF.

DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
3.2
CONTROL GROUP(S)
This is an open label, uncontrolled, first-in-human trial of the BET inhibitor BI 894999 in 
patients with advanced solid tumours and in a cohort of patients with DLBCL, following a dose 
escalation trial design, based on BLRM with overdose control. 
The starting treatment schedule was a continuous daily dosing in 3-week cycles. An additional 
intermittent dosing schedule with 2 weeks on and one week off treatment in 3-week cycles 
(Schedule B) was investigated in parallel, starting at the highest dose investigated in Schedule 
A in solid tumours which was considered to be safe by the DMC.
Once the MTD of both Schedules A and B in solid tumours was determined, the DLBCL 
cohort started using the MTD of the selected schedule (B) determined in the solid tumour 
cohort of this Schedule minus one dose level as the starting dose. This MTD determination in 
DLBCL was started in parallel with the MTD extension cohort in patients with solid tumours 
with the selected schedule (B). After MTD was confirmed for Schedule B in the patients with 
solid tumours, recruitment was opened to Phase Ib expansion cohorts in SCLC, mCRPC, CRC 
and NC patients with selected Schedule B. These cohorts are closed to recruitment at the time 
of protocol version 12.0 and only the cohort of NC patients with Schedule C is ongoing in the 
Phase Ib expansion.
The MTD will also be determined with Schedule C in DLBCL patients. Once the MTD of both 
Schedules B and C in DLBCL will be determined, the MTD cohort in DLBCL patients will be 
further extended using the selected schedule (B or C) to have a total of 12 to 14 DLBCL 
patients treated at the MTD of the selected schedule.
In parallel to MTD determination in DLBCL for both Schedules B and C, a Schedule C was
tested in patients with solid tumours to determine the MTD in this schedule and then the MTD 
cohort will be further extended to up to 12 patients.
An escalation with overdose control design will increase the chance of treating patients at 
efficacious doses while reducing the risk of overdosing. This design is based on practical 
experience and is a preferable algorithmic method due to its superior ability to identify the dose 
with the desired toxicity rate and its allocation to a greater proportion of patients to doses at or 
close to that dose (R13-4802, R13-4804, R13-4805).
SELECTION OF TRIAL POPULATION
3.3
A log of all patients enrolled into the trial (i.e. who have signed informed consent) is
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
Main diagnosis for trial entry
3.3.1
Patients with advanced, unresectable and/or metastatic solid tumours, who have failed 
conventional treatment or for whom no therapy of proven efficacy exists, or who are not 
amenable to standard therapies are eligible for the escalation part (Phase Ia) of this trial.

For patients in the DLBCL cohort, eligible patients are patients with histologically confirmed 
DLBCL, for whom there are limited or no standard treatment options available.
Fresh tumour biopsies at screening and under treatment, between Day 8 and Day 11 of the first 
cycle are mandatory for patients with solid tumours treated in the expansion Phase Ib with 
Schedule B. The fresh tumour biopsies at screening may be replaced by sending of archival 
tumour tissue provided that it was taken from the most recent relapse and not older than 6 
months. The on treatment biopsy may remain optional if no easily accessible lesions are 
available. 
Tumour biopsies are however not requested for mCRPC patients with only bone metastases
and for patients with therapeutic INR because of treatment with a vitamin K antagonist or a 
novel oral anticoagulant. The tumour biopsies remain optional for NC patients and for patients 
with solid tumours or DLBCL treated in the Phase Ia, including the MTD extension cohorts.
The platelet count and coagulation must be checked prior to each biopsy and must be adequate
with platelets of at least 50 000/mm3 without the support of transfusion and normal coagulation 
parameters. Should the biopsy under treatment with Schedule B, between Day 8 and Day 11 of 
Cycle 1 not be feasible in 5 of the first 20 patients of Phase Ib (see 3.1), the timing of biopsy 
under treatment in Cycle 1 will be moved ahead, between Day 3 and Day 8 for the next 
patients. 
Patients in the expansion part (Phase Ib) must in addition to the Phase Ia criteria for solid 
tumours, have progressive disease within the last 6 months and have one of the four types of 
solid tumours selected for the expansion cohorts. The tumours that are investigated in the four 
expansion cohorts of Phase Ib are SCLC, mCRPC, CRC and NC out of which only the NC 
cohort with Schedule C is ongoing at the time of protocol version 12.0.
Patients who are responding to treatment or who are benefiting from treatment may provide 
optional consent to undergo a fresh tumour biopsy (platelet count and coagulation must be 
checked prior to the biopsy and must be adequate, see above) at the time of response and also 
provide optional consent for their archival tumour sample to be analysed. If they give consent 
for these to be done, a sample of 2-3 mL EDTA blood DNA tube is mandatory.
Please refer to Section 8.3.1 (Source Documents) for the documentation requirements 
pertaining to the in- and exclusion criteria.

Removal of patients from therapy or assessments
3.3.4
Removal of individual patients
3.3.4.1
A patient has to be withdrawn from the treatment and/or the trial if:

The patient withdraws consent for study treatment or study participation, without the need 
to justify the decision

The patient is no longer able to participate (e.g. severe AEs, surgery, disease progression, 
concomitant diagnoses, concomitant therapies or administrative reasons, occurrence of a 
second cancer). The investigator may also stop the patient’s participation, if the patient is 
no longer able to attend the visits e.g. due to worsening of disease. For NUT carcinoma, 
patients are allowed to continue the trial treatment after progression as long as, based on the 
investigator’s judgement, they have a clinical benefit to continue and there are no further 
treatment options available

If eligibility criteria are violated in such a way that it might put the patient at risk if they 
continue on the trial treatment or the patient fails to comply with the protocol (e.g. non -
compliance to study visits, to study treatment)

The patient experiences a COVID-19 infection confirmed by a PCR test and the 
Investigator judges that the benefit-risk balance is not in favour of resuming treatment with 
BI 894999 after recovery from the infection
For all patients the reason for withdrawal (e.g. AEs) must be recorded in the electronic Case 
Report Form (eCRF). These data will be included in the trial database and reported.
As soon as a patient is withdrawn from the trial and given the patient’s agreement, the patient 
will undergo the procedures for early treatment discontinuation and follow up as outlined in the 
Flow Chart and in Section 6.2.3.
After withdrawal, the patient will further receive the available treatment for his condition at 
investigator’s discretion.
Patients withdrawn for another reason than DLT or patients who miss more than one visit 
during their first treatment cycle will be replaced. Patients who miss one visit may be replaced 
after discussion between the sponsor and the investigator if the information that needed to be 
collected during this visit is not available and makes the patient non-evaluable for 
pharmacokinetics analyses or safety parameters (including evaluation for DLT).
Patients who take incomplete doses or miss two doses or more of BI 894999 during their first

Discontinuation of the trial by the sponsor
3.3.4.2
Boehringer Ingelheim, after consultation with DMC, reserves the right to discontinue the trial 
overall or at a particular trial site at any time for the following reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. Emergence of any efficacy/safety information invalidating the earlier positive benefit-risk-
assessment that could significantly affect the continuation of the trial. In such case the 
patient will be withdrawn from treatment and discontinued from trial. Further treatment 
will be based on investigator’s judgment
3. Violation of good clinical practice (GCP), the clinical trial protocol (CTP), or the contract 
disturbing the appropriate conduct of the trial
The Investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).

4.1.2
The first part of the study is an open label, dose escalation Phase Ia study. Patients with solid 
tumours will enter treatment according to the next available slot determined via an Interactive 
Response Technology (IRT) system, at the time they are enrolled, being it for Schedule A, for 
Schedule B or for Schedule C. The DLBCL cohort of selected schedule (B) was only opened to 
DLBCL patients once the MTD had been determined for both Schedules A and B in patients 
with solid tumours and the recommended Schedule had been determined by the DMC
(Schedule B). Starting from protocol version 11.0 onwards, DLBCL patients will enter 
Schedule C for MTD determination after MTD has been determined for Schedule B. After 
DLBCL Schedule C dose escalation is complete, the DMC will then recommend the Schedule 
to further use for the extension of the DLBCL MTD cohort. 
For Schedule C dose finding in patients with solid tumours, only a limited number of sites in 
Belgium will recruit patients (e.g., the two initial sites in Belgium at the start of schedule C, 
with the possibility to extend to additional Belgian sites, as needed) and for these sites, Phase

Ia inclusion will have privilege over Phase Ib, should a patient be eligible for any of the two 
parts of the study.
In the second part (Phase Ib), patients were treated with the schedule and dose determined by
the DMC based on the safety, pharmacokinetic and biomarker results from the Phase Ia part in 
solid tumours, which was Schedule B. Furthermore, only patients with one of the four types of 
solid tumours were enrolled to Part Ib. Once MTD was determined for Schedule C in solid 
tumours patients of Phase Ia, and the DMC recommended Schedule C as selected schedule for 
further recruitment of patients in the NC cohort, the NC cohort with Schedule B was closed and 
a NC cohort with Schedule C opened for up to a maximum of 40 patients.
At the end of the screening period or during the first visit of Cycle 1, once the patient’s 
eligibility is confirmed but before any drug administration, the dose and the bottles of treatment 
are assigned via IRT. To facilitate the use of the IRT, the investigator receives all necessary 
instructions in the ISF.


Haematology: neutropenia, leukopenia, thrombocytopenia

Biochemistry: increased liver function tests (AST, ALT, bilirubin and alkaline 
phosphatase), increased creatinine.
Once a patient experienced such a drug related AE, the single patient cohort was expanded to a 
total of 3 patients. This cohort and all subsequent dose cohorts were then to be treated 
according to a BLRM.
For any dose-escalation cohort after a drug related CTCAE ≥ grade 2 (as listed above) during 
Cycle 1 was observed, at least 3 patients were required, but two out of those patients must be 
evaluable patients (DLT evaluation in 21 days of first cycle for Schedules A and B, in 28 days 
of first cycle for Schedule C) to make the decision on the dose for the next patients/cohort. The 
DMC will also recommend the size for the next cohort up to six patients. However, the final 
decision on the next cohort size will be made by a mutual decision between the TMM and the 
Coordinating Investigator. 
After all patients in a cohort have either experienced a DLT or have been observed for 21 days
in the first cycle without experiencing a DLT (28 days in the first cycle for Schedule C), the 
BLRM will be updated with the newly accumulated data and the overdose risk will be 
calculated. Based on the model and on additional information (e.g. patient profiles, PK, 
pharmacodynamics biomarkers) when available at the time of decision, the members of the 
DMC will reach a joint decision on the next dose level to be investigated.
For each new dose tier, the second patient may only be included from day 8 onwards in the first 
cycle of the first patient. If no serious drug-related AE (serious adverse event (SAE)) occurs in 
the first patient, the next patients within the same cohort may be simultaneously included. The 
decision regarding the magnitude of the dose escalation/de-escalation steps will only be taken 
by the DMC, considering toxicity data from each patient cohort.
During the expansion phase, a patient who experiences a DLT will undergo dose de-escalation 
in the same way as patients treated in the dose escalation phase but the occurrence of a DLT 
will not lead to a change in MTD. However any DLTs occurring in the expansion Phase Ib will 
be considered in the evaluation of the recommended Phase II dose and schedule. In the NC
population of the expansion phase, the DMC will have meetings after the first and after the 
second adolescent patient finishes the first cycle to assess whether the adult dose is tolerable in 
adolescents.
4.1.3.2
Additional cycles of BI 894999
Patients who tolerate the trial drug and experience at least disease stabilisation or an 
improvement of disease-related symptoms according to the investigator’s judgement may 
continue treatment. The dose of BI 894999 administered in further cycles must be the same as 
the dose administered in the previous cycle, unless the patient experienced dose limiting 
toxicity or any drug related significant AE necessitating a dose reduction according to 
investigator’s judgement (see Section 4.1.4).

Drug assignment and administration of doses for each patient
4.1.4
At the first visit of each cycle, the patient will receive the necessary amount of medication 
bottles from the applicable strength(s) to cover for the cycle period. The treatment numbers of 
the bottles will be assigned via the IRT system (see Section 4.1.2). If slots were available to 
patients with solid tumours at the same time in Schedules A and B, patients were allocated in 
priority to Schedule A in order to determine MTD. If slots were available at the same time in 
Schedule C and in the expansion Phase Ib in one of the sites participating in recruitment for 
Schedule C in patients with solid tumours, patients were allocated in priority to Schedule C in 
order to determine MTD. For DLBCL slots, patients are included in Schedule C since MTD 
has been determined for Schedule B.
The trial drug administration will happen at the clinical site on the days of visits or outside the 
clinical site on the other days, in the morning of each day, at approximately the same hour of 
the day if possible (e.g. 1h before breakfast, except for the 
 cohort), according to the 
schedule (see Flow Chart). 
Patients experiencing emesis may not take a replacement dose. 
If a patient forgets to take a dose, he/she may not take it if more than 3 hours elapsed after the 
normal hour for intake. He/she will then simply take the next dose at the planned time. The 
patient will be instructed to never take two doses to make up for the forgotten dose as BI 
894999 must not be taken more than once a day under any circumstances.
During the COVID-19 pandemic, physical visits to the sites may need to be restricted to ensure 
patient’s safety. Based on a thorough assessment of the benefits and risks, the investigator may 
still decide to continue the trial treatment and trial medication may be shipped to the patient’s 
home if acceptable according to local law and regulations. This will also be applicable in the 
post-pandemic context, after approval of protocol version 12.0 (for more details see Sections
6.1 and 10.5).
Cycle 1 
4.1.4.1
The trial drug administration should be started in the morning of the first treatment day. The 
assigned dose for a patient, according to the dose tier and treatment schedule will be 
administered at the investigational site on the morning of Day 1, after an overnight fast and 1 
hour before breakfast (with exclusion of the patients participating to the food interaction sub-
study, see Section 10.2.2), and the tablets must be swallowed with at least 250 mL water. On 
Day 2, while the patient is still kept at the institution, the dose is given after the PK sample and 
whole blood sample for 
 gene expression at 24h post-dose have been taken (not 
applicable anymore for NC patients and DLBCL patients after protocol version 12.0 approval 
where the visit of Day 2 is cancelled). 
The next doses will be taken by the patient outside of the clinical site up to day 7 (except third 
dose for the 
 cohort, see Appendix 10.2.2). 
On the mornings of Day 8 and Day 12 for Schedules A and B, the patient came to the 
investigational site with his/her medication bottle(s) without having taken his/her morning dose
and he/she received his/her dose after the necessary visit procedures happened, including PK 
sample before the drug was administered (see Appendix 10.2). 
For Schedules A and B, on Day 14 and Day 15 (not on Day 15 in Schedule B), the dose was
given at the investigational site after the PK sample and whole blood samples for HEXIM1 
gene expression pre-dose and at 24h post-dose had been taken. In Schedule B, the medication

bottle(s) were returned to the site on Day 14. For Schedule C, on Day 15 and on Day 21, the 
dose is given at the investigational site, on Day 21 after the PK sample and whole blood 
samples for HEXIM1 gene expression pre-dose have been taken.
The other doses of the cycle will be taken by the patient outside of the clinical site. 
On all days when there is no safety lab sampling to be taken which includes fasting blood 
glucose, the patient should however have an overnight fast before the drug intake and should 
not eat until one hour after drug intake. Medication should not be taken together with a meal.
On Day 22 in Schedule A, the patient returned the medication bottle(s) from Cycle 1 to the 
investigational site. For the three Schedules, he/she will receive his/her dose of the first day of 
next cycle, if applicable, from the bottle(s) of the second cycle, after the necessary visit 
procedures happened.
The exact time of trial medication intake on the investigational site must be recorded in the 
eCRF as this information is crucial for proper evaluation of pharmacokinetics and other data. 
Tumour biopsy (where applicable) must be performed in Cycle 1, between Days 8 and 11 
(between Day 3 and Day 8 if not feasible between Day 8 and Day 11 (see 3.1) for patients in 
Schedule A or B, between Days 18 and 21 for patients in Schedule C), 4h to 8 h after the daily 
dose of BI 894999 has been taken.
The patient will record the date and time of each medication intake during the first cycle in a 
diary to help with the compliance check. 
Each time the patient comes to the trial site for a visit (up to Day 14 in Schedule B, up to Day 
21 in Schedule C) he/she will bring his/her medication bottles and patient diary card (in first
cycle) and a compliance check must be performed. Discrepancies between the number of 
tablets remaining and the number of tablets the patient should have taken must be documented 
and explained, whenever possible (see 4.3). 
During the first cycle, the patient may interrupt treatment (not including the one week 
scheduled treatment break in Schedule B or the two times one week treatment break in 
Schedule C) only in case of a DLT (see 5.3.6.1) or at the end of the evaluation period of 21 
days (28 days in Schedule C) for recovery of another drug-related AE of CTCAE grade 3 or 4.
Further Cycles
4.1.4.2
For all subsequent cycles, the medication intake will happen outside of the clinical site except 
on the first day of each cycle (first two days for Cycle 2 in Schedule B, Days 1 and 15 in 
Schedule C) when it has to be administered at the trial site following an assessment by the 
investigational team, and he/she will have to return all the received medication bottles at the 
end of cycle visit.
Starting from protocol version 12.0 onwards, for NC and DLBCL patients, if the patient is 
unable to travel frequently to the site and if deemed safe by the investigator, the investigator 
may instead organize for the patient to have examinations of visit on Day 15 of any Cycle after 
Cycle 1 performed locally, close to the patient’s home, if allowed by local country regulations. 
The investigator must ensure that the persons and facilities executing the local tests are 
adequately qualified for performing those tests. The investigator will then have, as a minimum,
a phone call visit with the patient to evaluate the patient’s safety based on 
 conversation with 
the patient and the results from the local tests. In this case, the patient will take his medication 
at home on Day 15 of the cycle.

The Day 1 tests of even cycles, from Cycle 6 onwards may also be performed locally, close to 
the patient’s home with a phone call visit with the site investigator to evaluate the patient’s
safety, if the patient is unable to travel frequently to the site. It means that a drug dispensation 
may happen for two consecutive cycles on Day 1 of uneven cycles starting from C5 onwards, 
after discussion with the Sponsor, and if deemed safe by the Investigator. Alternatively, if 
applicable by the local regulation in the given country, a direct shipment from the site to the 
patient may happen, but in this case, via a courier approved by the Sponsor and aware of the 
procedure set-up by the Sponsor to ensure the correct conditions of the shipment.
In parallel to Schedule A an alternative Schedule B was started at the same dose tier at which 
the highest safe continuous daily dosing in 3-week cycles was investigated, according to DMC 
decision. An additional Schedule C was tested in patients with solid tumours, in parallel to 
Schedule B dose finding in DLBCL patients, starting with the recommended phase Ib dose of 
2.5 mg as maintenance dose from Day 2 to Day 7 and from Day 16 to Day 21 and a loa ding 
dose of 5 mg on Day 1 and Day 15, in 4-week cycles.
As the MTD was determined for DLBCL patients in Schedule B, the Schedule C is also being
tested in patients with DLBCL, starting with a loading dose of 4 mg and a maintenance dose of 
2 mg in the first cohort.
For a patient to be eligible for treatment with further cycles, the following criteria must be met:

Absence of disease progression (except for NC patients deriving clinical benefit and for 
whom no other treatment option is available)

Acceptable tolerability: patients experiencing DLT are eligible for further treatment cycles 
with BI 894999 at one dose tier below as soon as recovery from drug related toxicities 
allows further treatment. This means for Schedule C, a reduction of the loading dose in 
steps of 1 mg and a reduction of the maintenance dose in steps of 0.5 mg (e. g., for the first 
cohort, the loading dose would be reduced from 5 mg to 4 mg, from 4 mg to 3 mg, from 3 
mg to 2 mg while the maintenance dose would be decreased from 2.5 mg to 2 mg, from 2 
mg to 1.5 mg, from 1.5 mg to 1 mg).
Patients eligible for a further (repeat) treatment cycle will not start before day 22 after start of 
the previous cycle (Day 29 for Schedule C). 
Before the start of each next cycle, any remaining medication from the previous cycle must be 
collected. If the patient is eligible for a further cycle of treatment, new bottle(s) must be 
dispensed.
Dose interruptions and reductions
4.1.4.3
4.1.4.3.1
Dose interruptions
Dosing will be interrupted for any patient that experiences a dose limiting toxicity as defined in 
5.3.6.1.
Patients may continue therapy at a reduced dose of BI 894999 only after recovery from the 
DLT to at least CTCAE grade 1 or baseline level (except peripheral sensory neuropathy,
anaemia or lymphopenia where treatment continuation is allowed at CTCAE grade 2). 
At the end of the 21 day cycle, for Schedules A and B or 28 day cycle for Schedule C, dosing 
may be interrupted (i.e. start of next cycle postponed) at investigators discretion for recovery of 
other drug-related AEs of CTCAE grade 3 or 4 that do not qualify for DLT.

AEs of increased troponin
A CTCAE grade 3 troponin increase that is considered to be drug related qualifies for DLT 
according to 5.3.6.1 and will lead to an immediate dose interruption and additional cardiac 
investigations (e.g., review by a cardiologist, CK/CKMB, ECG, echocardiography) must be
performed as soon as possible to determine whether there is evidence of relevant 
cardiotoxicity. Only in case these investigations rule out new or emerging cardiotoxicity, the 
patient can resume treatment with BI 894999 upon recovery of the troponin increase to a grade 
1 or baseline and at a reduced dose according to the DLT rules (see 4.1.4.3.2). Intensified 
cardiac monitoring will be performed in these cases by evaluation of LVEF before the re-start 
of treatment and every 2 cycles thereafter to detect any new impaired wall motility or an 
indisputable drop of LVEF (percentage points reduction of ≥10 from baseline value or drop of 
LVEF below 50%, corresponding to a CTCAE grade 2) which would lead to drug 
discontinuation. 
AE of COVID-19 infection
In case of COVID-19 infection confirmed by a PCR test, the treatment with BI 894999 should 
be interrupted until recovery. The patient may resume treatment following recovery if the 
patient is expected to derive clinical benefit, as agreed between the Investigator and the 
Sponsor.
4.1.4.3.2
Dose reductions
If an AE is a DLT, the dose of BI 894999 must be reduced and treatment can continue only 
after sufficient recovery as explained in Section 4.1.4.3.1.  
In case of DLT, the new dose of BI 894999 will be the one used at the previous dose tier of one 
of the treatment schedules used in the study (e.g., dose reductions from 2.5 mg to 2 mg, from 2 
mg to 1.5 mg, from 1.5 mg to 1 mg). For Schedule C this applies to the loading dose which will 
be decreased in steps of 1 mg while the maintenance dose will be decreased in steps of 0.5 mg.
If an AE is not a DLT, the dose of BI 894999 should be kept the same and treatment can 
continue only after sufficient recovery as explained in Section 4.1.4.3.1. The BI 894999 dose 
may be reduced as a result of non-DLT AEs if deemed safer for the patient by the investigator.
For patients delaying the subsequent cycle by more than 14 days because of a drug related AE, 
treatment should be continued at a reduced dose.
Once a dose reduction occurred, the patient must continue at the reduced dose and cannot be 
re-escalated later on.

TREATMENT
Rescue medication, emergency procedures, and additional treatment(s)
4.2.1
Rescue medication to reverse the action of BI 894999 is not available.
Potential adverse reactions of BI 894999 have to be treated symptomatically.
In patients with DLBCL who are at risk of developing Tumour Lysis Syndrome (TLS), it is up 
to the investigator’s discretion what monitoring and precautionary measures are to be taken (for 
example, hydration, administration of allopurinol or rasburicase) in these patients. In the event 
that a patient develops TLS, he/she should be treated according to the institutional or standard 
guidelines and the TLS reported as an AE.
Concomitant therapy must be recorded in the eCRF, during the screening and treatment period, 
starting at the date of signature of informed consent, and ending at the end of the residual effect 
period (REP), 30 days after the last study drug intake (see Section 5.3.7). For parenteral 
nutrition during the trial, the components need not to be specified in detail. It should just be 
indicated as ‘parenteral nutrition’. 
After the REP, only concomitant therapy indicated for treatment of a related AE has to be 
reported. The start of a new anti-cancer treatment will be documented in the eCRF on the 
patient’s status page of the follow-up visit.

During the first cycle, the use of growth factors for treatment of evident haemato-toxicity is not 
allowed except under life-threatening circumstances in patients with solid tumours (allowed for 
DLBCL patients). After the first cycle, the use of haematologic growth factors (e.g. 
granulocyte colony stimulating factor (G-CSF), granulocyte macrophage colony stimulating 
factor (GM-CSF), erythropoietin, platelet-stimulating agents, pegylated G-CSF) in case of 
haematological toxicity of the experimental compound BI 894999 will be considered and 
discussed within the team if required. If this is the case, it has to be recorded in the eCRF 
including duration and dose of the treatment. 
If any diarrhoea is experienced (CTCAE grade ≥2), the patient must be treated with 
antidiarrheal treatment according to the local standard (for example loperamide two 2 mg 
tablets taken immediately, followed by one 2 mg tablet with every loose bowel movement, up 
to a maximum daily dose of 8 tablets (16 mg)).
In the event of diarrhoea, patients must be advised to avoid lactose-containing products or any 
foods known to aggravate diarrhoea.
Oral hydration is essential regardless of severity; appropriate rehydration (1.5 L/m2/day plus 
equivalent of actual fluid loss) and electrolyte replacement has to be ensured in the event of 
CTCAE grade 2 and grade 3 AEs.
In case of nausea and/or vomiting, the patient must be treated according to the local standard 
or according to the recommendations given in the Consensus Statement of the Anti-emetic 
Subcommittee of the Multinational Association of Supportive Care in cancer (MASCC): 
Prevention of chemotherapy- and radiotherapy-induced emesis: results of the Perugia 
Consensus Conference (R06-0986).
Symptomatic drug treatments of adverse reactions or tumour-associated symptoms are allowed, 
including the use of LHRH agonists or antagonists, steroids (given at the lowest possible dose 
and for the shortest possible duration to keep interference with response evaluation at the 
minimum, if introduced during the study treatment period), bisphosphonates and denosumab. 
It is possible that some patients treated with BI 894999 will experience concurrent severe 
thrombocytopenia and changes in coagulation lab assays. The coexistence of thrombocytopenia 
and changed coagulation lab results potentially increases the risk of bleeding events. In order to 
reduce the risk of bleeding events in patients with severe thrombocytopenia and prolonged 
coagulation times, mandatory prophylactic platelet transfusions need to be administered to all 
patients who present with a platelet count below 20 000/mm3.
Restrictions
4.2.2
Restrictions regarding concomitant treatment
4.2.2.1
Additional systemic anti-cancer therapies or curative radiotherapy is not allowed during the 
study. 
For symptom control, palliative radiotherapy is permitted for any lesion in the dose escalation 
part of the study, except during the first cycle if it is considered by the investigator and the 
TMM that it could interfere with the DLT evaluation for MTD determination. In the expansion 
phase (Part Ib), palliative radiotherapy is only allowed to non-target lesions, following 
discussion with the TCM, provided that the reason for radiotherapy does not reflect PD and 
does not interfere with response assessment (for NUT carcinoma patients, palliative 
radiotherapy to target lesions or to lesions that indicate PD is allowed for patients that are

deriving clinical benefit from the study treatment as confirmed by the investigator). Lesions 
that have been exposed to radiotherapy are no longer evaluable, and may not be included in the 
assessment of the non-target lesions (or target lesions for NC patients) and the overall 
assessment. These lesions may also not be used anymore for the study biopsy. Unless in 
emergency situations, the TCM should be contacted prior to the administration of palliative 
radiotherapy in the expansion phase.
During the first cycle, the use of growth factors for prevention or treatment of evident haemato-
toxicity is not allowed in patients with solid tumours (allowed for DLBCL patients) except 
under life-threatening circumstances (see Section 4.2.1).
Because of the non-clinical (in vitro) finding of the potential CYP inducing effect of BI 894999 
on CYP3A4, CYP 2C8 and CYP 1A2 , there is a risk that BI 894999 might reduce the plasma 
concentrations of some concurrent medications which are substrates of CYP3A4, CYP2C8 and 
CYP1A2, for example oral contraceptive pills, potentially resulting in a reduction in their 
effectiveness. There, the investigators should be aware of this when concomitant medications 
which are substrates of these CYP enzymes are given to the patient, with attention to a 
potential decrease of efficacy of the concomitant medication (a list of medications considered 
clinically relevant substrates of CYP 1A2, CYP 2C8 and CYP 3A4 is given in in Appendix 
10.6).
Restrictions on diet and life style
4.2.2.2
The usual restrictions on diet and life style which were already applicable for a given patient 
before entry into the study, according to his/her medical condition, have to be continued.
During treatment with BI 894999, all study patients will be advised to avoid sun exposure or 
artificial UVA/UVB radiation in solaria or tanning booths. If exposure to sunlight cannot be 
avoided, protective clothing and broad spectrum (UVA/UVB) sunscreens must be used. After 
discontinuation of BI 894999 treatment, all protective measures must be continued for at least 1 
week.
Restrictions regarding women of childbearing potential 
4.2.2.3
Women of childbearing potential must be ready and able to use highly effective methods of 
birth control per ICH M3(R2) that result in a low failure rate of less than 1% per year when 
used consistently and correctly, and this during the trial and for at least six months after the end 
of the trial treatment (see Section 3.3.2 and explanation given in the informed consent 
information form for more information on highly effective methods of birth control). Women 
of childbearing potential taking a contraceptive pill as birth control method must use an 
additional barrier method for the entire duration of the study treatment intake and for up to one 
month after the end of the study treatment intake.
Male patients with partners of childbearing potential need to use condoms and ensure their 
partner is using an additional highly effective method of birth control, during the trial and until 
at least three months after the end of the trial treatment.

TREATMENT COMPLIANCE
4.3
Patients are requested to bring all remaining trial medication including empty package material 
with them when attending visits. Based on tablet counts, treatment compliance will be 
calculated as the number of tablets taken, divided by the number of doses which should have 
been taken according to the scheduled period, multiplied by 100. Compliance will be verified 
by the on-site monitor authorised by the Sponsor.
Treatment compliance (%) =
Number of tablets from each strength actually taken 100
Number of tablets from each strength which should have 
been taken
If the number of tablets taken is not between 80-100%, site staff will explain to the patient the 
importance of treatment compliance.

VARIABLES AND THEIR ASSESSMENT 
Safety data will be collected and evaluated routinely on an ongoing basis.
TRIAL ENDPOINTS
5.1
Primary Endpoint(s)
5.1.1
Phase Ia
5.1.1.1
The primary endpoint for the Phase Ia part of the study is the number of patients with DLT (see 
Section 5.3.6.1 for definition of DLT) observed during the first treatment cycle (the first 21 
days for Schedules A and B, the first 28 days for Schedule C), which will be assessed for dose 
escalation in order to meet the objective of the determination of the MTD of BI 894999 for 
each schedule in patients with solid tumours and for the Schedules B and C in the DLBCL 
cohort.
Phase Ib
5.1.1.2
For the Phase Ib part of this study, the primary endpoint is the number of patients with DLTs
observed during the entire treatment period (as assessed approximately every 3 weeks, at the 
end of each new cycle after Cycle 2, every 4 weeks for Schedule C in the NC cohort if this 
cohort is opened to recruitment) for patients who are enrolled in one of the four pre-selected 
types of cancer in the Phase Ib part and are treated at the Phase Ib dose and schedule 
recommended by the DMC as determined from the Phase Ia part and ongoing safety data 
collected during Phase Ib.
All DLTs occurring during the entire treatment period will be considered for the evaluation of 
the recommended Phase II dose and schedule of BI 894999 and the recommended dose and 
schedule will be re-evaluated based on BLRM and other data collected from Phase Ib.
Secondary Endpoint(s)
5.1.2
Secondary endpoints are:
For Phase Ia

the number of patients with DLTs (see Section 5.3.6.1 for definition of DLT) observed 
during all treatment cycles for each of the schedules (A, B and C) in patients with solid 
tumours and for the Schedules B and C in the DLBCL cohort
All DLTs occurring during the entire treatment period for Schedules A and B will be 
considered for the evaluation of the recommended Phase Ib dose of BI 894999.
All DLTs occurring during the first or repeated treatment cycles will be reported as significant 
AEs, as if an SAE (see Section 5.3.6.1).


Objective response (OR), defined as CR or PR with tumour assessment during treatment 
period for each schedule (see 5.2.1). For DLBCL patients, a minor response according to 
RECIL 2017 is not part of an objective response
For Phase Ib:

Progression-free survival (PFS) defined from date of start of BI 894999 to the date of 
objective disease progression or death, whichever is earlier, with tumour assessment every 
2 cycles (every 6 weeks for Schedule B if no delays or as close as possible to the end of the 
second of the two cycles of treatment if there was a delay) during treatment period

Best overall response, with tumour assessment according to Section 5.2.1, depending on the 
type of solid tumour, during treatment period

PSA response in patients with mCRPC (see 5.2.1)

Overall survival in patients with NC. This will be for patients in the trial after approval of 
protocol version 11.0 and who gave consent to this collection. The overall survival status 
will continue until 12 months after the end of trial as defined in Section 8.6.

ASSESSMENT OF EFFICACY
5.2
Tumour assessment
5.2.1
The tumour response will be evaluated:

using the RECIST 1.1 (R09-0262), with tumour assessment every 2 cycles (every 6 
weeks if no delays for Schedules A and B, every 8 weeks for Schedule C or as close as 
possible to the end of the second of the two cycles of treatment if there was a delay) 
during treatment period for each schedule in all patients with solid tumours 

using PCWG3 (R17-3377) recommendation every 4 cycles (12 weeks if no delays or as 
close as possible to the end of the second of the four cycles of treatment if there was a 
delay) based on bone scan coupled with PSA percentage change at the same time-points 
as bone scan for mCRPC patients without measurable disease according to RECIST 1.1 
in Phase Ib

using RECIL 2017 (R17-3378) (see Appendix 10.7) based on FDG-PET/CT scans for 
selected schedule (A or B) in the DLBCL cohort every 2 cycles during first four cycles, 
then every four cycles. The assessment of overall response rate in DLBCL will only 
include patients who achieve a partial or a complete response
The assessment by the investigator and/or the local radiologist will be the basis for 
continuation or discontinuation of the trial in an individual patient (in addition to safety). 
The baseline scan(s) (CTscan, bone scan, FDG-PET/CT scans, and/or MRI according to 
investigator’s decision) from screening must have been performed within six weeks prior to 
treatment with the trial drug and the investigator will record results of assessment in the 
patient’s medical records and in the eCRF before the start of treatment according to the 
assessment method: 
-
According to RECIST 1.1, the target (five target lesions in total and maximum two per 
organ) and non-target lesions at baseline. 
-
According to RECIL 2017, target (up to three target lesions in total) and non-target 
lesions at baseline.

-
According to PCWG3: on bone scan, 2 new lesions are considered as progressive 
disease. 
The same method of assessment and the same technique must be used to characterise each 
reported lesion at baseline and during treatment. Lesions in previously irradiated areas may not 
be considered measurable or evaluable at baseline unless the lesions occurred after irradiation. 
A tumour lesion used for biopsy is not to be considered as a target lesion. 
Tumour response assessment will be performed every two cycles (every 4 cycles after Cycle 4 
in DLBCL patients, every 4 cycles for bone scan in mCRPC patients) and at the EOT visit (if 
not performed within the last 6 weeks).
PSA evaluation in mCRPC patients:

A PSA response is defined as a decline in PSA value ≥50% from baseline (which is 
confirmed by a second value 3 to 4 weeks apart)

A PSA progression is a 25% or greater increase in PSA, and an absolute increase of 2 
ng/mL or more from the nadir and which is confirmed by a second value 3 or more weeks 
later
A rising PSA corresponding to the definition of disease progression (see definition above) is 
not a reason on its own to stop with the trial treatment in mCRPC patients otherwise benefitting 
from the treatment but is considered as PD if concomitant with 2 new bone lesions on bone 
scan or PD according to RECIST 1.1 or clinical evidence of PD.
If the patient stops with the trial medication intake for another reason than PD, the tumour 
assessment according to RECIST, RECIL or PCWG3 will be performed according to standard 
of care until the last follow-up needed according to protocol (progression, death, lost to follow-
up, end of the trial).
For the NC patients, the overall clinical benefit assessment per Investigator’s judgement will be 
based on the following points:

response (CR, PR or SD, mixed response)

symptom relief such as pain, breathing problems, other improvements (Investigator to 
specify)

other reason for considering the clinical benefit (Investigator to specify)
ASSESSMENT OF SAFETY
5.3
Physical examination
5.3.1
Physical examination, height, body weight, performance status
5.3.1.1
Physical examination will be performed at screening, on visit 1 of each cycle prior to study 
medication intake and at the EOT visit. 
Physical examination will include e.g. measurement of height and of body weight and the 
evaluation of the ECOG performance score. Height will be documented only once during 
screening. Weight will be measured during screening, on visit 1 day 1 of each cycle, at the

EOT visit and at FU. The ECOG score will be assessed during screening, on visit 1 day 1 of 
each cycle, and at the EOT and FU visits. 
For DLBCL patients, a tumour size determination (by palpation) will be performed at 
screening and at the first visit day of each cycle. For the lymph nodes, only the largest lymph 
node per area will be assessed in two dimensions (if greater than 1 cm in any diameter, which 
can be physically assessed). The spleen and liver enlargement will be expressed in cm below 
the costal margin. Any other tumour manifestation will also be evaluated in two dimensions.
Vital Signs
5.3.2
Vital signs (blood pressure, body temperature and pulse rate after 2 minutes supine rest) will be 
recorded at the screening visit, at every visit of the treatment cycles and at the EOT visit. In 
addition, during the first cycle, vital signs will be measured more frequently on PK sampling 
days (see Flow Chart).
Safety laboratory parameters
5.3.3
Blood (venous) samples will be collected at the times indicated in the Flow Chart and analysed 
by the site’s local safety laboratory.
Laboratory tests will include the following safety lab parameters:

Haematology
Red blood cell count (RBC), haemoglobin, haematocrit, mean corpuscular volume (MCV), 
white blood cell count (WBC) and differential expressed in absolute values, platelets

Biochemistry
Fasting glucose (after overnight fast), sodium, potassium, calcium, phosphate, urea, creatinine, 
AST, ALT, alkaline phosphatase, lactate dehydrogenase (LDH), bilirubin, total protein, 
albumin, uric acid, creatine phosphokinase (CK) and highly sensitive (hs) troponin (T or I, 
according to the laboratory assay used at a given site, but always with the same method for a 
given patient) must be performed and the findings documented.
In case of significant troponin hs increase, further investigations according to standard clinical 
practice should be undertaken by the investigator as deemed appropriate (see Section 
4.1.4.3.1).
Monitoring for TLS includes the following tests:

uric acid, creatinine

sodium, potassium, calcium, phosphate

lactate dehydrogenase (LDH)

Coagulation parameters
Prothrombin time (PT) (expressed in seconds and in international normalized ratio (INR)) and 
activated partial thromboplastin time (aPTT); at screening, in Cycle 1: on day 1 before the first

dose of BI 894999, on day 2, on day 8, on pre-dose on the day of tumour biopsy when 
applicable and on day 14, on the first day of every next cycle and on day 15 of Cycles 2, 3 and 
4 and at EOT. In addition, activity of factors II, V, VII and IX will be measured in the first 20 
patients of the Phase Ib in Cycle 1 on Day 1 before first dose of BI 894999 and on Day 14 as 
well as on Cycle 2 Day 1 pre-dose. 
In patients with out of range coagulation lab results (PT, aPTT) in the routine safety laboratory 
assessments, additional coagulation investigations should be performed as appropriate and 
guided by the specific lab findings (such as analysis of single coagulation factor activity and 
mixing studies to distinguish factor deficiencies from inhibitors) in order to investigate the 
underlying reasons for the prolongation of coagulation times.

Virology, only at screening (starting from protocol version 9.0 onwards)

Hep B DNA test, 

Hep C RNA test 

HIV test with an established HIV diagnostic assay
Tests results obtained within 4 weeks of screening are acceptable and must be negative for 
inclusion of the patient in the trial.

Urine 
Urine (pH, glucose, erythrocytes, leukocytes, protein, nitrite) will be analysed by dipstick 
(semi-quantitative measurements) during the screening visit, at visit 1 Days 1 and 2, at visits 4 
and 5 of initial treatment cycle, at visit 1 of repeated treatment cycles and at the EOT visit. In 
case of pathological findings, further evaluation must be performed and the findings 
documented.

Pregnancy test
Beta human chorionic gonadotrophin (β-HCG) pregnancy test in urine or serum will be 
performed for women of childbearing potential at screening, within 7 days prior to first study 
treatment and before the start of each repeated cycle as well as at the EOT visit.
These parameters will be assessed as specified in the Flow Chart. In case of toxicity, adequate 
and more frequent blood sampling is at the discretion of the investigator. In the event of grade 
4 neutropenia or grade 4 thrombocytopenia, blood will be examined at least twice weekly after 
the first occurrence of the grade 4 until return to a lower grade and then further followed at the 
discretion of the investigator.
In case where laboratory investigations have been performed more than 72h prior to the first 
study treatment intake, the results of new laboratory investigations performed within 72h
before the first treatment administration must be available and confirm eligibility.
Electrocardiogram
5.3.4
In Cycle 1, standard 12-lead resting (after at least 5 minutes rest in the supine position) ECGs
matched with PK samples will be performed according to the Flow Chart and in the Appendix
10.2, as much as possible in triplicate. At screening and in patients eligible for repeated cycles 
of treatment, standard (triplicate) 12-lead resting digitalized ECGs must be done according to

the Flow Chart (before the intake of BI 894999 at the start of a new cycle) and whenever the 
investigator deems it necessary. An ECG will also be performed at the EOT visit and at the 
follow-up visit (optional if performed at the EOT visit and no drug related abnormalities were 
detected in on-study ECGs).
In case of drug related ECG changes, additional ECG monitoring will be performed in the 
respective and later cycles of treatment, as deemed necessary by the investigator.
All ECGs have to be digitally recorded, if possible in triplicates, within a period of maximum 3 
minutes, using dedicated equipment provided by the CRO and sent electronically to the CRO.
When the ECG time point is concomitant with a blood sampling (or any other procedure), the 
ECG must always be performed prior to the blood sampling (or other procedure) to allow the 
recording in reproducible resting conditions. Detailed instructions for correct ECG recording 
are provided in the ISF.
If for a visit, the patient has the assessments performed locally and not on the clinical site, the 
ECG will not be performed on the central reading ECG device and the ECG tracing must be 
sent to the site which will send it to the Central Reading laboratory for evaluation. 
The recordings will be checked for pathological results (to be recorded as AEs) by the 
investigator. In addition a centralised evaluation of all 12-lead ECGs will be performed by the 
CRO for all ECGs sent to them. This analysis will include the determination of RR-intervals, 
PR-intervals, QRS-intervals, QT-intervals. The CRO is also in charge of a safety over read of 
ECGs (one ECG out of every series of three) which will be done by a board -certified 
cardiologist. In case of clinical abnormalities detected by the cardiologist, the report will be 
provided to the investigator via email or fax by the central reading laboratory and will be 
reported as an AE by the investigator if not already spontaneously reported. 
To allow for a heart rate correction of QT intervals the QT intervals will be matched to the 
preceding RR intervals using at least QTcF (Fridericia’s formula QTcF = QT * RR-1/3) and 
QTcB (Bazett’s formula QTcB = QT * RR-1/2 ).
When preliminary PK results are available (e.g. at the end of the escalation phase), ECG 
recording time points may be adjusted, or new time points may be added according to the 
pharmacokinetic profile of BI 894999.
Other safety parameters
5.3.5
Left ventricular ejection fraction
5.3.5.1
Due to the cardiac findings seen in some patients in this first in human trial as described in 
Section 2.3, the decision has been taken to add an echocardiography or MUGA scan at 
screening and then at the end of Cycle 2 and at EOT (if not performed within the last 6 weeks 
before and if the patient’s health status allows), in order to assess the LVEF. Additional 
measures must be performed in case a grade 3 troponin increase is seen (see Section 4.1.4.3.1).
The same method of measurement (echocardiography or MUGA scan) should be used 
throughout the study.

Echocardiography should be performed according to the standard guidelines of the American 
Society of Echocardiography (ASE) (R16-5269).
Assessment of adverse events
5.3.6
Definitions of AEs 
5.3.6.1
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily 
have to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Serious adverse event
A SAE is defined as any AE which:

results in death,

is life-threatening,

requires inpatient hospitalisation or prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity,

is a congenital anomaly/birth defect,
or

is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardize the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Life-threatening in this context refers to an event in which the patient was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death if 
more severe.
Every new occurrence of cancer of new histology must be reported as a serious event 
regardless of the duration between discontinuation of the study drug and the occurrence of the 
cancer.
AEs considered “Always Serious”
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of AEs, which by their nature, can always be considered 
to be “serious” even though they may not have met the criteria of an SAE as given above.
The latest list of “Always Serious AEs” can be found in the remote data capture 
(RDC)/electronic data capture (EDC) system. These events must always be reported as SAEs 
as described in section 5.3.6.1.

The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. AESI 
need to be reported to the Sponsor’s Pharmacovigilance Department within the same timeframe 
that applies to SAE, see Section 5.3.7.
The following are considered as AESIs:
Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory parameters: 
For patients with normal hepatic function at baseline

an elevation of AST and/or ALT >3 fold the Upper Limit of Normal (ULN) combined with 
an elevation of total bilirubin >2 fold ULN measured in the same blood draw sample, 
and/or

marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
For patients with abnormal hepatic function at baseline (e.g., due to primary liver cancer or 
hepatic metastases)

an elevation of AST and/or ALT ≥5 fold ULN combined with an elevation of bilirubin ≥2 
fold ULN measured in the same blood draw sample. 
These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the “Drug Induced Liver Injury (DILI)
checklist” provided via the RDC-system/EDC-system. Lab values meeting the hepatic injury 
definition must always be reported as an AESI. Exemption does not apply.
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results (ALT, 
AST, total bilirubin) available, the investigator has to make sure these parameters are analysed, 
if necessary in an unscheduled blood test. Should the results meet the criteria of hepatic injury 
alert, the procedures described in the DILI checklist must be followed.
Any DLT:
The following drug related AEs will qualify as a dose limiting toxicity: 
For solid tumours patients:

Any CTCAE grade ≥3 non haematological toxicity considered related to trial medication
with the following exceptions:

inadequately treated nausea, vomiting or diarrhoea. For fatigue, if present at baseline, 
there must be an increase of 2 grades, 

electrolytes abnormalities that can be corrected within 72 hours with adequate treatment 
(in case it occurs, a control should be performed at 72h to determine the 72h duration of 
the grade 3)

Any hematologic AE related to the trial medication defined as follows:

CTCAE grade ≥4 neutropenia lasting ≥ 7 days (in case it occurs, a control haematology 
test must be performed at least twice weekly until improvement to a lower grade) 
and/or complicated by infection, or


CTCAE grade≥4 thrombocytopenia (in case it occurs, a control haematology test must 
be performed at least twice weekly until improvement to a lower grade), or

CTCAE grade≥ 3 thrombocytopenia coupled with grade ≥ 2 of bleeding, or

Febrile neutropenia CTCAE grade 3 (ANC<1000/mm3 and fever ≥ 38.5°C) or higher, 

Any other drug-related AE preventing the patient from taking his treatment according to 
the given schedule (defined as more than 2 consecutive doses missed during the 21 days of 
intake of the Cycle for Schedule A or 14 days of intake for Schedule B or during the two 
times one week of intake of Schedule C or a treatment break between cycles > 14-days in 
addition to the one week off foreseen in Schedules B and C).
For DLBCL patients:

Any CTCAE grade ≥3 non haematological toxicity considered related to trial medication 
with the following exceptions:

inadequately treated nausea, vomiting or diarrhoea. For fatigue, if present at baseline, 
there must be an increase of 2 grades), 

electrolytes abnormalities that can be corrected within 72 hours with adequate treatment 
(in case it occurs, a control should be performed at 72h to determine the 72h duration of 
the grade 3)

Any hematologic AE related to the trial medication defined as follows:

CTCAE grade ≥4 neutropenia lasting ≥ 7 days (in case it occurs, a control haematology 
test must be performed at least twice weekly until improvement to a lower grade) 
and/or complicated by infection, or

CTCAE grade ≥ 4 thrombocytopenia (in case it occurs, a control haematology test must 
be performed at least twice weekly until improvement to a lower grade), or

CTCAE grade≥ 3 thrombocytopenia coupled with grade ≥ 2 of bleeding, or

Febrile neutropenia CTCAE grade 3 (ANC<1000/mm3 and fever ≥ 38.5°C) or higher 
which does not resolve within 48 hours with appropriate treatment (antibiotics, 
antifungal, antiviral agents and growth factors), 

Any other drug-related AE preventing the patient from taking his treatment according to 
the given schedule (defined as more than 2 consecutive doses missed during the 14 days of 
intake in Schedule B which is selected, or treatment break between cycles > 14-days in 
addition to the one week off foreseen in Schedule B).
For definition of DLT, it is essential that patients are sufficiently treated according to 
supportive care standards (see 4.2.1). Patients with treatable AEs (nausea, vomiting, and 
diarrhoea) that are not sufficiently treated do not qualify for DLT and need to be 
replaced, if this occurs in Cycle 1.
AESIs are to be reported in an expedited manner similar to SAEs, even if they do not meet any 
of the seriousness criteria – for details please see 5.3.7.
Severity of AEs
The severity of the AE must be classified and recorded in the eCRF according to CTCAE
version 4.03 in the eCRF (R10-4848).

Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Yes:
There is a reasonable causal relationship between the investigational product 
administered and the AE.
No:
There is no reasonable causal relationship between the investigational product 
administered and the AE.
The causal relationship must be provided by the Investigator for all potential trial drugs, i.e. the 
BI trial drug.
Adverse event collection and reporting
5.3.7
AE Collection
The Investigator shall maintain and keep detailed records of all AEs in their patients’ files
The following must be collected and documented on the appropriate eCRF by the Investigator:
-
From signing the informed consent onwards through the REP, until the end of the REP:
- all AEs (non-serious and serious) and all AESIs.
-
After the end of the REP until individual patient’s end of trial:
- all related SAEs and all related AESIs.
After the individual patient’s end of trial, the investigator does not need to actively monitor the 
patient for AEs but must only report relevant SAEs and relevant AESIs of which the 
investigator may become aware of.
IC = informed consent
End of treatment = last dose of BI 894999
REP = residual effect period of 30 days
End of trial = individual patient’s end of trial = last visit mandated per protocol which is the first follow-up if the patient 
stopped study treatment because of PD or the follow-up at which PD is observed or the decision is taken to start with the 
next line of cancer treatment or the last ongoing patient has reached the first follow-up at the end of the REP

The REP is defined as 30 days after the last trial medication intake. All AEs which occurred 
through the treatment phase and throughout the REP will be considered as on treatment please 
see Section 7.3.4. Events which occurred after the REP will be considered as post treatment 
events.
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, by completing and sending the BI SAE form immediately (within 24 
hours ) to the Sponsor’s unique entry point (country specific contact details will be provided in 
the ISF). The same timeline applies if follow-up information becomes available. In specific 
occasions the Investigator could inform the Sponsor upfront via telephone. This does not 
replace the requirement to complete and send the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
Information required
For each AE, the Investigator must provide the information requested on the appropriate eCRF 
pages and the BI SAE form, e.g. onset, end date, intensity, treatment required, outcome, 
seriousness, and action taken with the investigational drug(s). The Investigator must determine 
the causal relationship to the trial medication.
The following must also be recorded as an (S)AE in the eCRF and SAE form (if applicable):

Worsening of the underlying disease (if not part of the exemption as described below) or 
other pre-existing conditions

Changes in vital signs, ECG, physical examination and laboratory test results, if they are 
judged clinically relevant by the Investigator.
If such abnormalities already pre-exist prior to trial inclusion, they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after trial completion must be followed up until they 
have resolved, have been sufficiently characterized, or no further information can be obtained.
Pregnancy
In the rare case that a female subject participating in this clinical trial becomes pregnant after 
having taken trial medication, the Investigator must report immediately (within 24 hours) the 
drug exposure during pregnancy (DEDP) to the Sponsor’s unique entry point (country-specific 
contact details will be provided in the ISF). The Pregnancy Monitoring Form for Clinical Trials 
(Part A) must be used. 
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the Sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B). 
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is

to be completed. If there is an SAE and/or AESI associated with the pregnancy then the SAE
and/or AESI has to be reported on the SAE form in addition. 
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
Exemptions to SAE Reporting
Progressive disease (PD) in oncology trials is a study endpoint for analysis of efficacy. PD is 
exempted from reporting as a (S)AE. Progression of the subject's underlying malignancy will 
be recorded in the appropriate pages of the eCRF as part of efficacy data collection. Death due 
to PD is to be recorded on the appropriate eCRF page and not on a SAE form.
Examples of exempted events of PD are:

Progression of underlying malignancy (PD): if PD is clearly consistent with the suspected 
progression of the underlying malignancy as defined by the respective response criteria. 

Hospitalization/Procedures due solely to the progression of underlying malignancy (PD)

Clinical symptoms and/or signs of progression (with or without confirmation by objective 
criteria e.g. imaging, clinical measurement): if the symptom can exclusively be determined 
to be due to the progression of the underlying malignancy and does meet the expected 
pattern of progression for the disease under study.
When there is evidence suggesting a causal relationship between the study drug and the event 
of progression of the underlying disease, the event must be reported as (S)AE in the eCRF and 
on a SAE form (if applicable).
The study is monitored by a DMC in order to review data on a regular basis.
DRUG CONCENTRATION MEASUREMENTS AND 
5.4
PHARMACOKINETICS
Assessment of Pharmacokinetics
5.4.1
Standard pharmacokinetic parameters of BI 894999 as listed under secondary 
 
endpoints will be determined from plasma 
 analyses after a single oral dose and after 
repeated dosing, at steady state along with descriptive statistics. 
 
 
.
At any time, only in case of drug related grade 3 or grade 4 toxicity, every effort must be made 
to collect a plasma PK sample; date and time of the sample and of the most recent drug intake 
(before PK sample) need to be recorded for such samples.
Methods of sample collection
5.4.2
Plasma sampling for BI 894999 pharmacokinetics
5.4.2.1
For quantification of BI 894999 plasma concentrations, up to 102 mL blood will be taken from 
a forearm vein in an EDTA anticoagulant blood drawing tube at the time points specified in the 
Flow Chart and in Appendix 10.2.

Every attempt must be made to adhere to the time points for the sampling. For the quality of 
pharmacokinetic analysis, however, the actual times of drug intake and blood sampling as well 
as of dose administration are crucial. Therefore, exact and actual clock time of BI 894999 
intake and blood samplings have to be recorded in the eCRF. 
A total of two plasma aliquots will be generated (with about 0.7 mL plasma in each aliquot) 
from each blood sample. The first aliquot will be used primarily for PK bio-analysis of BI
894999 plasma concentrations, the second aliquot will serve as a back-up sample. The plasma 
samples (including PK back-up samples) must be stored at about -20°C or below at the clinical 
site until shipment on dry ice to the bio-analytical laboratory. There, they will also be stored at
about -20°C or below until analysis (see Section 5.4.3).
Details on sample collection, preparation of plasma aliquots, handling, storage and shipment 
are provided in the ISF/laboratory manual.
Urine sampling and analysis for pharmacokinetics
5.4.2.2
A blank urine sample will be collected prior to the first drug administration and two 4 mL 
aliquots retained to check for analytical interference. A protocol start time of -2:00 and a stop 
time of -2:00 will be used for database setup. All urine voided during the sampling intervals 
described in Appendix 10.2 will be collected in containers. Patients have to empty their bladder 
at the end of each sampling interval. The urine weight/volume (weight will be set equal to 
volume, i.e. 1 kg = 1 L, without correction for specific gravity of urine) for each collection 
interval will be documented (the weight of the empty and filled container needs to be 
documented) and two 4 mL aliquots will be stored for bio-analytical measurement. In order to 
prevent adsorption of BI 894999 it might be necessary to add an additive to the container prior 
to start of urine collection. The procedure and details will be given in the ISF/laboratory 
manual.
Until shipment on dry ice to the bio-analytical laboratory, the urine samples will be stored at 
about -20°C or below at the clinical site and in the same conditions at BI until analysis.
The urine sampling for PK will not happen anymore for the patients recruited under protocol 
version 12.0 onwards.

INVESTIGATIONAL PLAN
VISIT SCHEDULE
6.1
The study consists of two parts, a dose escalation part (Phase Ia) to determine the MTD in three 
different Schedules (Schedule A of continuous dosing, Schedule B with an intermittent dosing 
of 2 weeks on treatment followed by one week break in 3-week cycles, and, starting from 
protocol version 10.0 onwards, Schedule C with a once daily loading dose on Day 1 followed 
by 6 days daily intake of a maintenance dose then one week off treatment, repeated every two 
weeks in 4-week cycles) in patients with solid tumours. The best schedule of administration of 
BI 894999 in patients with solid tumours was determined between Schedules A and B. The 
schedule shown to have a more favourable safety, pharmacokinetics and biomarker profile was 
Schedule B which was chosen to be further investigated in an extension of MTD cohort in 
patients with solid tumours, to determine the MTD in a DLBCL cohort with extension of this 
cohort at MTD and in the expansion phase (Phase Ib). In addition, the 
 on the 
pharmacokinetics of BI 894999 was also investigated in some of the patients from the Phase Ia 
part (around and at MTD), starting in Schedule A and continuing in Schedule B in order to 
obtain results for at least 12 patients and up to 20 patients. Once MTD was determined for 
Schedule B in DLBCL patients, MTD will be determined as well with Schedule C in DLBCL 
patients. Thereafter, the DMC will recommend the best schedule of administration of BI 
894999 between Schedules B and C in patients with DLBCL. The schedule shown to have a 
more favourable safety, pharmacokinetics and biomarker profile will be chosen to be further 
investigated in an extension of MTD cohort in patients with DLBCL.
The second part (Phase Ib) is an expansion phase to further evaluate safety, efficacy and 
pharmacokinetics profile of BI 894999 in patients with selected types of solid tumours (SCLC, 
mCRPC, CRC or NC), as well as biomarker values as a result of treatment with BI 894999
with the selected schedule from Phase Ia, between Schedules A and B, which was B. Once the 
MTD from Schedule C from Phase Ia was known for patients with solid tumours, the DMC 
recommended the schedule shown to have a more favourable safety, pharmacokinetics and 
biomarker profile between B and C. Schedule C was selected, NC cohort with Schedule B was
closed to recruitment and NC cohort with Schedule C was opened..
Patients meeting the inclusion and exclusion criteria for the part they are participating in and 
who have given their written informed consent, are eligible for participation in the study.
Patients will visit the clinical site at the time points specified in the Flow Chart for the 
appropriate Schedule of dosing they are entering (see also Appendix 10.4 for a complete list). 
In situations where a patient is unable or unwilling to attend a clinic visit, the Investigator must 
assess the benefit-risk balance for the individual patient and may decide to perform a visit 
remotely if this is in the best interest of the patient and if agreed with the Sponsor, provided 
that it is allowed by local country regulations and the investigator ensures that the local 
facilities are adequately qualified to perform the tests required per protocol for the given visit.
If a patient misses a scheduled visit, and the patient reports to the investigator between the 
missed visit and the next scheduled visit, the missed visit must be done with the actual date and 
the reason must be given for the delayed visit. 
For the biopsies and PK sampling procedures of Cycle 1, the patient must however still be 
under treatment and not in a treatment break period to perform the evaluations foreseen during

the missed visit. The next visit must then take place at the scheduled time after the first 
administration of the trial drug in the respective treatment cycle.
Once the decision for any reason is taken for a patient to stop the treatment with BI 894999, an 
EOT visit must occur as soon as possible.
After the EOT visit, the patient must undergo a follow-up evaluation during an EOR visit (or at 
least a phone contact if a visit is not possible), 30 days (+ 7 days) after the last BI 894999 
intake. 
If the patient was not discontinued because of withdrawal of consent, disease progression,
treatment with another anti-cancer drug, loss to follow-up or because of the end of the trial, 
he/she must continue to undergo follow-up visits every 12 weeks until disease progression, lost 
to follow-up, treatment with another anti-cancer therapy or end of the trial. For NC patients, the 
survival status will be collected for all patients until death, lost to follow-up or until 12 months 
after the end of the trial, according to their consent, after approval of protocol version 11.0.
The study will be conducted according to the principles of Good Clinical Practice (GCP).
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS

DLBCL patients or based on bone scan and PSA level according to PCWG3 (R17-3377) in 
mCRPC patients of Phase Ib without measurable disease according to RECIST 1.1) must 
be performed once every 2 cycles (meaning every 6 weeks for Schedules A and B, every 8 
weeks for Schedule C, if no delays in cycles but as close as possible to end of the second of 
the two cycles of treatment if there was a delay), in DLBCL every 2 cycles until Cycle 4, 
every 4 Cycles thereafter, every 4 cycles in mCRPC patients) after start of BI 894999.

LVEF assessment at screening, at the end of Cycle 2 during the treatment period as well as

reason, as soon as possible but no later than 7 days after permanent discontinuation of the trial 
medication or when the investigator decided with the patient to permanently discontinue the 
trial medication or became aware that the trial medication had been terminated. 
The assessments of the EOT visit will then be performed instead of the next planned visit. For 
NC patients, overall clinical benefit based on investigator’s judgement will also be recorded
(see Section 5.2.1).

If the patient finishes active treatment without having progressive disease, tumour 
assessment/imaging must be performed at the time of treatment discontinuation, unless it has 
been done within the past 6 weeks. If active treatment is stopped due to progressive disease, 
then imaging must be performed at the point in time when progression is first noted 
irrespective of when the most recent imaging was done.
Follow-up visits
6.2.3.2
The REP is defined in Section 5.3.7. The first follow-up visit corresponds to the End of REP 
(EOR) visit and may not be performed earlier than 30 days after permanent discontinuation of 
the trial medication. The information collected at this visit must include all new AEs that 
occurred after EOT and a follow-up of AEs ongoing at EOT.
Additional follow-up visits after the EOR visit will only be performed for patients who did not 
progress on treatment, once every 12 weeks (at least by telephone) until disease progression, 
introduction of a new anti-cancer treatment, death, loss to follow-up or end of the whole trial as 
specified in Section 8.6.
A patient will be considered as having completed the study if he/she discontinues because of 
disease progression and has performed the EOR visit 30 days after EOT or was lost to follow-
up or withdrew consent for further evaluation at the EOT visit. If the patient discontinues for 
any other reason, he/she will be considered as withdrawn.
For NC patients, after approval of protocol version 11.0, the overall survival status will be 
collected, according to patient’s consent, until death, loss to follow-up, withdrawal of consent 
to be further followed-up or until 12 months after the end of the whole trial.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
STATISTICAL DESIGN - MODEL
7.1
This is a Phase I, open-label, dose-escalation trial to determine the MTD for three Schedules of 
BI 894999 in patients with solid tumour and for Schedule B and Schedule C in the DLBCL 
cohort and also to assess the safety profile, PK/pharmacodymamics biomarkers, and anti-
cancer activities of BI 894999.
Phase Ia:
The objective of the Phase Ia is to determine the MTD, defined as the highest dose with less 
than 25% risk of the true DLT rate being above 33%, separately for three Schedules of BI 
894999 in patients with solid tumour and for the Schedules B and C in the DLBCL cohort. 
Dose escalation and determination of MTD for Schedule A and Schedule B will be guided by a 
Bayesian 2-parameter logistic regression model with overdose control (R13-4803; R13-4806). 
Dose escalation and MTD determination for Schedule C will be guided by a Bayesian 5-
parameter logistic regression model with overdose control (R15-4233), which is described in 
statistical appendix section 10.3.2. These designs have been shown to be superior regarding the 
precision of MTD determination compared to 3+3 designs.
The Bayesian 2-parameter logistic regression model (BLRM) is formulated as follows:
logit(p(d)) = log(α) + β x log(d/d*),
where logit(p) = log(p/(1-p)). 
p(d) represents the probability of having a DLT in the first cycle at dose d, d* = 80 mg is the 
reference dose, allowing for the interpretation of α as the odds of a DLT at dose d*, and θ = 
(log(α), log(β)) with α, β > 0 is the parameter vector of the model.
Since a Bayesian approach is applied, a prior distribution π(θ) for the unknown parameter 
vector θ needs to be specified. This prior distribution used in the BLRM for the dose escalation 
of Schedule A will be specified as a mixture of three multivariate normal distributions, i.e.
π(θ) = φ1π1(θ) + φ2π2(θ) + φ3π3(θ)
with 
φi, i = 1, 2, 3 the prior mixture weights (φ1+ φ2+ φ3 = 1)
and 
πi(θ) = MVN(μi, Σi)
the multivariate normal distribution of the i-th component with mean vector μi and covariance 
matrix Σi, with

Mixture prior distributions have the advantage that they allow for specification of different 
logistic dose-toxicity curves, therefore making the prior more robust.
Initial prior derivation
For the current study of Schedule A dose escalation, no relevant information in the form of 
human data is available, since no study in a comparable population has been conducted. 
Therefore, the three mixture components were established as follows:
1. A weakly informative prior was derived to reflect a priori assumption that the median DLT 
rate at the starting dose of 0.2 mg would equal 1%, and the median DLT rate at 80 mg 
would equal 40%. This yields μ1 = (-0.402, -0.350). The standard deviations were set such 
that large uncertainty about the parameter means is reflected, and the correlation was set to 
0, thus yielding σ1,11 = 2, σ1,22  = 1 and ρ1 = 0, respectively. The prior weight φ1 for the first 
component was chosen as 0.9.
2. A high-toxicity weakly informative prior was derived to reflect the case that the compound 
would be much more toxic than expected. For this prior component, it was assumed that the 
median DLT rate at the starting dose of 0.2 mg would equal 10%, and the median DLT rate
at 80 mg would equal 60%. These assumptions yield μ2 = (0.409, -0.826). The standard 
deviations and correlations were set identical to the weakly informative prior, i.e. σ 2,11 = 2, 
σ2,22  = 1 and ρ2 = 0, respectively. The prior weight φ2 for the second component was 
chosen as 0.05.
3. A low-toxicity weakly informative prior was derived to reflect the case that the compound 
would be much less toxic than expected. For this prior component, it was assumed that the 
median DLT rate at the starting dose of 0.2 mg would equal 0.1%, and the median DLT
rate 80 mg would equal 5%. These assumptions yield μ3 = (-2.936, -0.413). The standard 
deviations and correlations were set to σ3,11 = 5, σ3,22  = 0.01, therefore almost fixing the 
slope parameter to its mean. The correlation was set to 0, i.e. ρ3 = 0. The prior weight φ3 for 
the third component was chosen as 0.05.
A summary of the prior distribution used in the BLRM for Schedule A dose escalation is 
provided in Table 7.1:1. Additionally, the prior probabilities of DLT at different doses, as well 
as the corresponding probability of under-, targeted and overdosing, are shown in Table 7.1: 2. 
Graphically, the prior medians with accompanying 95% credible intervals are shown in Figure 
7.1: 3. As can be seen from both the Table and the Figure, the prior medians of the DLT 
probabilities are in-line with the prior medians derived from the weakly informative prior, and 
the uncertainty around the medians is large, showing the low amount of information this prior 
provides. This is also supported by the prior sample size, i.e. the information contained in the 
prior. This is approximately equal to 1.22 patients, i.e. less than or around half of the weight 
the first cohort in the study will have.

Prior medians and 95% credible intervals
The priors may be updated once the trial has started in case new data that can be used will be 
available. After the initial prior derivation the five different BLRM models used for the dose 
finding of Schedule A in patients with solid tumour, of Schedule B in patients with solid 
tumour, of Schedule C in patients with solid tumour, of Schedule B in patients with DLBCL, 
and of Schedule C in patients with DLBCL will be handled separately.
For Schedule A and Schedule B, the MTD may be considered reached if the following criteria 
are fulfilled (for Schedule C, see Section 10.3.2)
1. At least 1 DLT on the trial and either
2. At least 6 patients have been treated at the MTD and the posterior probability of the true

60% for Schedule B dose escalation in solid tumour and the DLBCL dose escalation (due 
to the fact that an updated prior based on observed safety data from Schedule A dose
escalation is used for the Schedule B dose escalation in solid tumour and DLBCL dose 
escalation), OR
3. At least 12 patients in each schedule in solid tumours and in Schedule B in the DLBCL 
indication with 6 patients having been treated at MTD for each MTD determination.
Statistical model assessment
The model was assessed using two different metrics:
1. Hypothetical data scenarios: for various potential data constellations as they could occur in 
the actual trial, the maximal next doses as allowed by the model and by the 100% 
escalation limit are investigated. Data scenarios thus provide a way to assess the “on-study” 
behaviour of the model.
2. Simulated operating characteristics: these illustrate for different assumed true dose-toxicity 
relationships, how often a correct dose would be declared as MTD by the model. They are a 
way to assess the “long-run” behaviour of the model.
In summary, the model showed very good behaviour as assessed by these metrics. More details 
can be found in Section 10.3. The simulations for scenarios and operating characteristics were 
produced using R version 3.0.3.
With the addition of Schedule B and Schedule C in patients with solid tumour and Schedule B
and Schedule C in the DLBCL cohort after the start of Schedule A in patients with solid 
tumour, the initial priors used in the Bayesian logistic regression model were updated based on 
the cumulatively observed data. For Schedule C, loading dosing and maintenance dosing will 
be treated as a combination of BI 894999. The initial priors for maintenance dosing are updated 
based on the observed data from Schedule A and B in patients with solid tumour. More details 
can be found in Section 10.3 and TSAP.
Phase Ib:
The expansion Phase Ib will recruit a minimum of 9 patients and a maximum of 20 patients
with measurable disease according to RECIST 1.1 (mCRPC patients with no measurable-
disease are eligible according to PCWG3 criteria (see 3.3.2.1) to the dose and Schedule 
recommended by the DMC for Phase Ib part (based on MTD) per type of tumour (SCLC, 
mCRPC or CRC) selected by the DMC. For NC patients, up to 40 patients will be recruited 
with Schedule B and/or with Schedule C. 
Five patient cohorts are considered in the Phase Ib part of this study. To effectively use the 
information from these 5 patients’ cohorts in the assessment of the efficacy of BI 894999, a 2-
stage Bayesian hierarchical model (BHM) approach, which assumes full exchangeability of 
model parameters and allows borrowing information across patients’ cohorts, will be used to 
analyse the response rate endpoints (i.e. objective response rate, disease control rate). The 
BHM has 2 main components: a data model and a parameter model. The data model is a 
binomial sampling model
rj | nj ~ Binomial (πj, nj), j = 1, 2, 3, 4, 5

where nj and rj are the number of patients and the corresponding number of patients with 
response in each patient cohort. The parameter model for the exchangeable log-odds 
parameters θj = log(πj / (1 - πj)) is specified as
θj | μ, τ ~ N(μ, τ2), j = 1, 2, 3, 4, 5
where μ denotes the “overall” mean and τ determines the inter-cohort heterogeneity. A non-
informative (improper) uniform prior is used for the main parameter μ. For the inter-cohort 
heterogeneity parameter τ, a half-normal prior with scale parameter 100 is used which is a very 
conservative assumption regarding between-cohort variability and hence leads to only little 
borrowing of data across patient cohorts because there is little prior information on the strength 
of the correlation between the treatment effects across the 5 cohorts.
In stage 1 of the Phase Ib part, approximately 9 patients will be enrolled and treated in each of 
the SCLC, mCRPC and CRC cohorts. If no objective response is observed out of the 
approximate 9 patients in a patient cohort, this cohort will be closed for stage 2 recruitment.
Analysis of stage 1 may be performed for each cohort separately. At the end of stage 2 of the 
Phase Ib part, the BHM approach will be used to estimate the shrinkage estimator of θj for each 
patient cohort and the response data from the DLBCL MTD extension cohort will also be 
considered in the shrinkage estimator of θj. Since the full exchangeability assumption may not 
hold for the BHM, the exchangeability-non exchangeability (R17-3435) approach will also be 
applied as a sensitivity analysis of the response rate endpoints in the Phase Ib part.
NULL AND ALTERNATIVE HYPOTHESES
7.2
No formal hypothesis testing is planned in this trial. This is an exploratory Phase Ia/Ib study 
with the main objective of dose escalation and MTD determination (for Phase Ia part) and 
safety and efficacy evaluation (for Phase Ib part). All analyses in this trial are descriptive and 
exploratory by nature.
PLANNED ANALYSES
7.3
Only one analysis population will be considered for efficacy and safety analyses: the treated 
set. The treated set (TS) will consist of all patients who were treated with any dose of BI 
894999. Patients will be analysed under the actual treatment received on Day 1.
The PK set includes all subjects in the TS who provide at least one observation for at least one 
PK endpoint without important protocol violations relevant to the evaluation of PK.
The primary analysis will be based on the treated set population excluding patients that have to 
be replaced for analysis of the MTD, see Section 3.3.4.1 for further details.
No per protocol population will be used for analyses; however important protocol violations 
will be identified and listed.

Primary endpoint analyses
7.3.1
In order to determine the MTD, the occurrence of DLTs in the first cycle will be assessed on an 
individual patient level in Phase Ia part. The MTD will be determined as described in
Section7.1 for Schedules A and B in patients with solid tumour and in Section 10.3.2 for 
Schedule C. The description for MTD determination for Schedule B and Schedule C in the 
DLBCL cohort can be found in Section 7.1.
Based on the data observed in the trial, other models might be considered either additionally or 
replacing the primary model. For feasibility or other reasons, a different dose might be 
considered as the recommended dose for Phase Ib.
The number of patients with DLTs that occurred during the first treatment cycle (first 21 days
for Schedules A and B, first 28 days for Schedule C) in Phase Ia part and during the entire 
treatment period in Phase Ib part of this study will be summarized separately. For Phase Ia part 
of this study, the number of patients with DLTs during the first cycle will be summarized by 
dose level for each schedule (A, B and C) in solid tumour and for Schedule B and Schedule C
in the DLBCL cohort. For the Phase Ib part of this study, the number of patients with DLTs 
during entire treatment period will be summarized by different cohorts and the BLRM will be 
rerun to re-evaluate the MTD together with all relevant data collected in Phase Ib.
Secondary endpoint analyses
7.3.2
Descriptive analyses will be conducted for secondary endpoints.
Number of DLTs
The number of DLTs occurred during the entire treatment period in Phase Ia part of this study 
will be summarized by dose level for each schedule (A, B and C) in solid tumour and for 
Schedule B and Schedule C in the DLBCL cohort.
Secondary efficacy analyses
Objective response and best overall response assessed by the investigator according to RECIST 
version 1.1 for solid tumour in each schedule, or using RECIL 2017 for the DLBCL patients or 
via bone scan in combination with PSA evaluation, as well as the PSA responder rate will be 
analysed descriptively for each schedule in solid tumour and for Schedule B and Schedule C in 
the DLBCL cohorts. The number of patients with objective response and with best overall 
response will be summarized separately for the Phase Ia part and the Phase Ib part. For the 
Phase Ia part, frequency distribution and descriptive statistics will be provided by dose level for 
each schedule in solid tumour and for Schedule B and Schedule C in the DLBCL cohorts. For 
the Phase Ib part, a Bayesian hierarchical modelling approach will be used to derive the 
shrinkage estimators of the response rate endpoints of each patient cohort together with the 
95% credible interval. The MTD extension cohort of the DLBCL cohort will also be 
considered in the BHM of the shrinkage estimators of the response rate endpoints. In addition, 
the frequency distribution and descriptive statistics will also be provided for each patient 
cohort. A sensitivity analysis using the EXNEX method may also be conducted to account for 
non-exchangeability of the response rates across patient cohorts.

For PFS to be assessed for the Phase Ib part of this study, if a patient did not die or progress 
until the last visit in the study, this patient will be censored at the last time point known to be 
alive and progression-free. Kaplan-Meier method will be used to analyse PFS.
For patients with ‘event’ as an outcome for PFS:
• PFS [days] = date of outcome – date of the first treatment administration + 1.
For patients with ‘censored’ as an outcome for PFS:
• PFS (censored) [days] = date of outcome – date of the first treatment administration + 1.
For NC patients, overall survival is a secondary endpoint, defined as the time from the first 
treatment administration to the date of death. OS will be analysed descriptively by Kaplan-
Meier method.
For patients with ‘event’ as an outcome for overall survival:
• Overall survival [days] = date of death – date of the first treatment administration + 1.
For patients with ‘censored’ as an outcome for overall survival:

Safety analyses
7.3.4
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) coding 
dictionary. Standard BI summary tables and listings will be produced. All AEs with an onset 
between start of treatment and end of the REP, a period of 30 days after the last dose of trial
medication, will be assigned to the treatment period for evaluation under the treatment received 
on Day 1. The actual treatment at AE onset will be displayed in subject data listings.
All treated patients will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
Statistical analysis and reporting of AEs will concentrate on treatment-emergent AEs. To this 
end, all AEs occurring between start of treatment and end of the residual effect period will be 
considered ‘treatment-emergent’. The residual effect period is defined as 30 days after the last 
trial medication intake. AEs that start before first drug intake and deteriorate under treatment 
will also be considered as ‘treatment-emergent’.
Frequency, severity, and causal relationship of AEs will be tabulated by system organ class and 
preferred term after coding according to the current version of the MedDRA.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will be 
done via comparison of laboratory data to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listi ngs. 
Treatment groups will be compared descriptively with regard to distribution parameters as well 
as with regard to frequency and percentage of patients with abnormal values or clinically 
relevant abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, baseline, 
during the course of the trial and at the end-of-trial evaluation will be assessed with regard to 
possible changes compared to findings before start of treatment.
Pharmacokinetic analyses
7.3.5
For pharmacokinetic analysis and displays, concentrations will be used in the same format as 
reported in the bio-analytical report. Only concentrations within the validated concentration 
range and actual sampling times will be used for the calculation of pharmacokinetic 
parameters. For derivation of pharmacokinetic parameters see Appendix 10.1.
Non-compartmental pharmacokinetic analyses of the plasma concentration-time data will be 
performed using a validated software program (WinNonlin®Phoenix, current version) and for 
this purpose the actual sampling time for pre-dose samples will be set to zero.
Plasma concentrations will be plotted graphically versus time for all subjects as listed in the 
drug plasma concentration-time tables. For the presentation of the mean profiles, the arithmetic 
and geometric mean and the planned blood sampling times will be used. If the actual sampl ing

time deviates significantly from the planned time, the corresponding plasma concentration will 
be excluded from the calculation of descriptive statistics.
 
 
 
 
 
 
 
 
 
 
 
INTERIM ANALYSES
7.4
Interim safety evaluations will be performed as considered necessary. In particular safety 
evaluations will be performed after each dose cohort by the DMC consisting of the 
investigators and representatives of the sponsor (refer to Section 3.1.1). Based on this, the 
DMC will recommend the next dose level as well as the corresponding cohort size. DMC 
meeting minutes and outputs provided for these DMC meetings will be documented and 
archived in the TMF.
In the Phase Ib part of this study, an interim futility assessment will be conducted after 
approximate 9 patients are enrolled and evaluable for tumour response evaluation by imaging 
in each of the SCLC, mCRPC and CRC patients’ cohorts. If no objective response is observed 
in any of the patients in a cohort, this patient cohort will be closed for further enrolment. These 
futility assessments may be performed separately for each cohort.
 
Unblinded preliminary exploratoryPK analysis of BI 894999 and pharmacodynamics analyses 
will be performed each time it will be deemed necessary by the trial team and DMC to 
investigate the PK and pharmacodynamics characteristics of BI 894999.

The TCPK will receive the bio-analytical results to be able to perform the exploratory PK 
analysis from the Trial Bio-analyst (TBA).
 
 
 
 
Once the primary endpoint of the Phase Ia was reached in patients with solid tumours for both 
schedules A and B, and the MTD was confirmed in the extension cohort with the selected
schedule (B) in these patients, a Phase Ia report was prepared based on the Phase Ia data for 
patients with solid tumours in Schedules A and B. For this purpose, a database snapshot was
performed. A summary of safety and efficacy endpoints and determination of the 
recommended Phase Ib dose and schedule was included in the Phase Ia report. The Phase Ia 
report is made available for all investigators who participate in the Phase Ib. Once MTD in 
Schedule C will be determined and confirmed in the extension cohort, the report for Schedules 
A and B in solid tumours together with the results for Schedule C will be the basis for 
publication by the Coordinating Investigator. Prior to initiation of Phase Ib, relevant data from 
the Phase Ia part for Schedules A and B will also be sent to regulatory agencies in the countries 
where Phase Ia Schedules A and B took place and where Phase Ib will take place.
HANDLING OF MISSING DATA
7.5
Missing baseline laboratory values will be imputed by the respective values from the screening 
visit. No other imputations will be performed on missing data and every effort will be made to 
obtain complete information on all AEs with particular emphasis on potential DLT and to 
follow-up the patients for efficacy data.
Plasma concentration - time profiles
7.5.1
Concentration data identified with NOS (no sample), NOR (no valid result), NOA (not 
analysed), BLQ (below the limit of quantification), and NOP (no peak detectable) will be 
ignored and not replaced by zero at any time point (applies also to the lag phase including the 
pre-dose value). Descriptive statistics of concentrations at specific time points will be 
calculated only when at least 2/3 of the individuals have concentrations within the validated 
concentration range. The overall sample size to decide whether the “2/3 rule” is fulfilled will 
be based on the total number of samples intended to be drawn for that time point (i.e. BLQ, 
NOR, NOS, NOA, NOP are included).
Pharmacokinetic parameters
7.5.2
In the noncompartmental analysis, concentration data identified with NOS, NOR, and NOA 
will not be considered. BLQ and NOP values in the lag phase will be set to zero. The lag phase 
is defined as the period between time zero and the first time point with a concentration above 
the quantification limit. All other BLQ/NOP values of the profile will be ignored. If the pre-
dose concentration is less than or equal to 5% of Cmax value in that subject, the subject’s data

without any adjustments can be included in all pharmacokinetic measurements and calculations 
(i.e. the pre-dose value will not be changed to zero). If the pre-dose value is greater than 5% of 
Cmax, the subject should be dropped from all statistical evaluations. The individual 
pharmacokinetic parameters can be calculated and listed separately. Every effort will be made 
to include all concentration data in an analysis. If not possible, a case to case decision is 
required whether the value should only be excluded from half-life estimation or the complete 
analysis. 
• If a concentration is only excluded from half-life determination, it will be used for all other 
calculations (e.g. descriptive statistics) and for graphical presentation.
• If a concentration value is excluded from all calculations, it will not be presented graphically 
or used for the calculation of descriptive statistics and parameter determination. However the 
excluded concentration itself will be listed in the clinical trial report associated with an 
appropriate flag.
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual 
parameter estimates of a certain parameter are available. If the actual sampling time will not be 
recorded or will be missing for a certain time point, the planned time will generally be used for 
this time point instead. Pharmacokinetic parameters which cannot be determined will be 
identified by "not calculated”.
RANDOMISATION
7.6
Patients will be assigned, not randomised, into escalating dose cohorts by order of admission 
into the trial. Doses will be assigned based on the decision made by the DMC (see Section
7.3.4).
DETERMINATION OF SAMPLE SIZE
7.7
About 104 patients are expected for the Phase Ia dose escalation part:
-
47 patients were included for both Schedules A and B in patients with solid tumours
including a total of 12 patients in the MTD cohort of solid tumours for the selected 
schedule between A and B (B) (refer to Table 10.3.1: 3)
-
approximately 34 patients in the DLBCL cohort:14 patients were included to determine 
the MTD in Schedule B, 12 patients are expected to be necessary to determine the MTD 
in Schedule C and 6 up to 8 patients to confirm the MTD in the schedule selected by the 
DMC (B or C). 
-
Approximately 23 patients for Schedule C in patients with solid tumours (16 were 
necessary for MTD determination and an addition of 7 patients to confirm the MTD)
Fewer or more patients might be needed for the Phase Ia part based on the recommendation of 
the DMC and the criteria specified (see Section 7.1). 
 
 
About 80 up to100 patients are expected for the Phase Ib expansion part: 
Additional minimum 9 evaluable patients will be included in the Phase Ib expansion phase for 
each type of solid tumour (SCLC, mCRPC or CRC). If at least 1 out of 9 evaluable patients in a

given cohort has an objective response, the cohort would be further extended up to 20 patients. 
The 3 cohorts recruited respectively 12, 11 and 14 patients to reach the minimum of 9 
evaluable patients. The cohorts of CRC, mCRPC and SCLC didn’t pass the futility. 20 patients
with NC were recruited in Schedule B. Since 
Schedule C was selected after MTD 
determination of Schedule C in phase Ia solid tumour patientsas recommended by DMC, the 
NC cohort with Schedule B was closed and the NC cohort with Schedule C is recruiting up to 
40 patients.
Different homogeneous scenarios and heterogeneous scenarios are
considered in the 
simulations to assess the frequentist operating characteristics of the BHM approach for the 
Phase Ib part of the study. The simulation results as shown in Table 7.7: 1 below show that, 
with the proposed maximum cohort size of 20 patients and an interim futility assessment after 9 
patients in each patient cohort in the SCLC, CRPC and CRC cohorts, the BHM approach has 
high probability of making the correct decision under a wide range of scenarios of both 
complete exchangeability assumption and some “nugget” scenarios.

INFORMED CONSENT, DATA PROTECTION, TRIAL
RECORDS
The trial will be carried out in compliance with the protocol, the ethical principles laid down in 
the Declaration of Helsinki, in accordance with the ICH Harmonized Tripartite Guideline for 
GCP and relevant BI Standard Operating Procedures (SOPs), the EU regulation 536/2014 and 
the US FDA regulations.
For each US site / investigator incorporated under a US IND, the US IND requirements outlined in 
the US Code of Federal Regulations must also be met and a Form FDA 1572 needs to be filled in.
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The Investigator will inform the Sponsor immediately of any urgent safety measures taken to 
protect the trial subjects against any immediate hazard, and also of any serious breaches of the 
protocol or of ICH GCP.
The rights of the Investigator and of the Sponsor with regard to publication of the results of this 
trial are described in the Investigator contract. The abbreviated safety interim report written at 
the end of the Phase Ia for Schedules A and B in patients with solid tumours together with the 
results of primary endpoint in Schedule C in patients with solid tumours may be the basis for a 
publication. However, concerning all the trial results including the Phase Ib results, they may 
not be published prior to finalization of the Clinical Trial Report.
The certificate of insurance cover is made available to the Investigator and the patients, and is
stored in the ISF (Investigator Site File).”
TRIAL APPROVAL, PATIENT INFORMATION, AND INFORMED 
8.1
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective IRB / IEC and competent authority (CA) according to national and 
international regulations. The same applies for the implementation of changes introduced by 
amendments.
Prior to patient participation in the trial, written informed consent must be obtained from each 
patient or from the patient’s parents (both or one, based on national regulation) or from the legal 
guardian if the patient is not legally adult according to ICH / GCP and to the regulatory and legal 
requirements of the participating country. For a minor patient, in addition to the parents or legal 
guardian informed consent, the minor patient must also sign an informed assent. Each signature 
must be personally dated by each signatory and the informed consent and any additional 
patient-information form retained by the Investigator as part of the trial records. A signed copy 
of the informed consent and any additional patient information must be given to each patient or 
the patient’s legally accepted representative.
For patients < legal age to be adult: If only mother or father (or one legal guardian) has sole 
legal custody, this needs to be confirmed with signature and date on the informed consent by 
the person with legal custody. Both documents (consent and assent) outline the participant’s 
rights to decline to participate or to withdraw from the study at any time. Consenting/assenting

is a dynamic and continuous process that should be maintained during the trial. At each new 
treatment course the site staff should briefly discuss with legal representative for a minor 
patient and with the patient him/herself the main aspects of the trial, focusing in particular on 
any new information that might affect their willingness to continue the participation in the trial. 
The site staff is recommended to document this process in the medical records.
DATA QUALITY ASSURANCE
8.2
A quality assurance audit/inspection of this trial may be conducted by the Sponsor, Sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will have 
access to all medical records, the Investigator’s trial-related files and correspondence, and the 
informed consent documentation of this clinical trial.
RECORDS
8.3
eCRF for individual patients will be provided by the Sponsor. For drug accountability, refer to 
Section 4.1.8.
Source documents
8.3.1
Source documents provide evidence for the existence of the patient and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s site.
Data reported on the eCRF must be consistent with the source data or the discrepancies must be 
explained. The Investigator may need to request previous medical records or transfer records, 
depending on the trial; current medical records must also be available.
For the eCRF, all data need to be derived from source documents, e.g.:

Patient identification (gender, date of birth)

Patient participation in the trial (substance, trial number, patient number, date patient was 
informed)

Dates of Patient’s visits, including dispensing of trial medication

Medical history (including trial indication and concomitant diseases, if applicable)

Medication history

AEs and outcome events (onset date (mandatory), and end date (if available))

SAEs (onset date (mandatory), and end date (if available))

Concomitant therapy (start date, changes)

Originals or copies of laboratory results (in validated electronic format, if available)

Originals or copies of imaging diagnostics

ECG results (original or copies of printouts)

Completion of Patient’s Participation in the trial

Prior to allocation of a patient to a treatment into a clinical trial, there must be documented 
evidence in the source data (e.g., medical records) that the trial participant meets all 
inclusion criteria and does not meet any exclusion criteria. The absence of records (either 
medical records or testing conducted specific for a protocol) to support inclusion/exclusion 
criteria does not make the patient eligible for the clinical trial.

Technical information collected on PK sampling days (such as i.e. PK sampling times, weight 
of containers for urine PK, repeated vital signs linked with PK) may be collected on specific 
paper PK logs which will be considered as source data for related entries in eCRF and are 
considered part of the ISF.
Direct access to source data and documents
8.3.2
The Investigator / institution will permit trial-related monitoring, audits, IRB / IEC review and 
regulatory inspection, providing direct access to all related source data / documents. eCRF and 
all source documents, including progress notes and copies of laboratory and medical test results 
must be available at all times for review by the Sponsor’s clinical trial monitor, auditor and 
inspection by health authorities (e.g. FDA). The CRA / on site monitor and auditor may review 
all eCRF, and written informed consents. The accuracy of the data will be verified by 
reviewing the documents described in Section 8.3.1.
LISTEDNESS AND EXPEDITED REPORTING OF ADVERSE EVENTS
8.4
Listedness
8.4.1
To fulfil the regulatory requirements for expedited safety reporting, the Sponsor evaluates 
whether a particular AE is "listed", i.e. is a known adverse reaction of the drug or not. 
Therefore, a unique reference document for the evaluation of listedness needs to be provided. 
For BI 894999, this is the current version of the Investigator’s Brochure (c03016865-02). 
The current version of this reference document is provided in the ISF. No AEs are classified as 
listed for trial design, or invasive procedures.
Expedited reporting to health authorities and IRB / IEC
8.4.2
Expedited reporting of SAEs, e.g. suspected unexpected serious adverse reactions (SUSAR) to 
health authorities and IRB / IEC, will be done according to local regulatory requirements. BI is 
responsible to fulfil their legal regulatory reporting obligations and in accordance to the 
requirements defined in this protocol.
STATEMENT OF CONFIDENTIALITY
8.5
Individual patient medical information obtained as a result of this trial is considered 
confidential and disclosure to third parties is prohibited with the exceptions noted below. 
Patient confidentiality will be ensured by using patient identification code numbers.
Treatment data may be given to the patient’s personal physician or to other appropriate medical 
personnel responsible for the patient’s welfare. Data generated as a result of the trial need to be 
available for inspection on request by the participating physicians, the Sponsor’s 
representatives, by the IEC and the regulatory authorities.
END OF TRIAL
8.6
The end of the trial is defined as the time when the last ongoing patient in the trial will have 
undergone the EOT visit and the EOR visit.

APPENDICES
PHARMACOKINETIC ANALYSES
10.1
Concentrations will be used for calculations in the format that is reported in the bio-analytical 
report. The data format for descriptive statistics of concentrations will be identical with the data 
format of the respective concentrations. For the calculation of pharmacokinetic parameters, 
only concentrations within the validated concentration range will be used. The actual sampling 
times will be used. For pre-dose samples, the actual sampling time will be set to zero. Non-
compartmental pharmacokinetic parameters will be determined using WinNonlin or another 
validated program.
Analyte plasma concentrations will be plotted graphically versus time for all subjects as listed 
in the analyte plasma concentration-time tables.  For the presentation of the mean profiles, the 
arithmetic/geometric mean and the planned blood sampling times will be used. 
In the following, the derivation of parameters that are determined after the first dose as single 
dose parameters and after the last dose of cycle 1as steady state parameters are described 
together, whereby (ss) denotes the steady state parameters. The derivation of parameters is no t 
affected by the attainment of steady state.
Cmax
Individual Cmax
values will be directly determined from the plasma 
concentration time profiles of each subject. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
AUC: The area under the curve will be calculated using the linear up/log down algorithm. If an 
analyte concentration is equal to or higher than the preceding concentration, the linear 
trapezoidal method will be used. If the analyte concentration is smaller than the preceding 
concentration, the logarithmic method will be used.
Linear trapezoidal rule (t2 > t1 and Ct2 Ct1):
The area of the trapezoid between the two data points (t1, Ct1) and (t2, Ct2) will be computed by:

STATISTICAL APPENDIX INCLUDING MODEL PERFORMANCE AND 
10.3
DATA SCENARIOS
Model Performance and Data Scenarios for Schedules A and B
10.3.1
The model was assessed by two different metrics: hypothetical on-study data scenarios and 
long-run operating characteristics. The simulations for scenarios and operating characteristics 
were produced using R version 3.0.3.
Hypothetical data scenarios
Hypothetical data scenarios are shown in Table 10.3.1:1. These scenarios reflect potential on-
study data constellations and related escalation as allowed by the model. For each scenario, the 
probability of overdose for the current dose, the next optimal dose recommended by the model 
in terms of the probability of target dose, and the next maximal dose allowed by the model due 
to the bound of the overdose probability are shown. Furthermore the related probabilities of 
under-dosing, target dose, and overdosing for the next optimal dose are presented. The actual 
dose chosen for the next cohort, not shown in Table 10.3.1: 1, will be determined by the DMC 
after taking into consideration of the recommended dose from the model as well as other 
relevant data from this study.
For example, scenario 1 represents the case that no DLT is observed in the first patient at the 
starting dose of 0.2 mg. In this case, the next optimal dose, i.e. the dose with the highest 
probability of being in the target interval, is 40 mg. However since this dose has an overdose 
probability higher than 0.25, the next dose maximally allowed by the model is 20 mg. Similarly 
scenarios 2, 3, 5, 8, 9, 11, 12, 13 and 16 represent cases where no DLTs are observed. In 
scenario 4, one DLT is observed already in the patient at the second lowest dose level. There, 
the model recommends stopping the trial, because all pre-specified dose levels have high 
overdose probabilities. The same holds for scenario 7.
Finally, scenarios 14, 15, 17, and 19 illustrate cases where no DLTs are observed in the first 
patient cohorts and then DLTs occur in the higher dose levels. In scenarios 14 and 15, the 
model requires to re-enrol at 40 mg and at 80 mg, respectively. In both scenarios 17 and 19, 2 
DLTs occur which lead to a direct reaction of the model despite the fact that no DLTs were 
seen in the previous cohorts. It therefore recommends de-escalating to lower dose levels. These 
cases illustrate the adaptive behaviour of the model even in extreme situations.

**Overdose-probability of the next optimal dose is too high (violates EWOC criterion), 
therefore the maximal allowed dose would be chosen as next dose by the model.
Operating characteristics
Operating characteristics are a way to assess the long-run behaviour of a model. Under an 
assumed true dose-toxicity curve, metrics such as the probability of recommending a dose with 
true DLT rate in the target interval can be approximated via simulation. Table 10.3.1: 2
describes 5 assumed true dose-toxicity scenarios which were used to assess the operating 
characteristics of the model. These scenarios reflect a wide range of possible cases. Scenario 1 
represents the DLT rates that are aligned with prior means per dose level. Scenarios 2 and 3 
reflect the extreme cases of very high and very low toxicity probabilities, respectively. 
Scenario 4 covers the case of a true dose-toxicity relationship that does not have a logistic 
form. Finally, scenario 5 reflects the possibility of having very low DLT rates at the lower dose 
levels and high DLT rates at the upper dose levels.

Bold numbers indicate true DLT rates in the target interval [0.16, 0.33].
For each of these scenarios, 1000 trials were simulated. It was then assessed how often a dose 
was declared as MTD with true DLT rate in the under-, targeted or over-dose range. 
Furthermore, the average, minimum and maximum number of patients per trial and the average 
number of DLTs per trial are reported. Results are shown in Table 10.3.1: 3.

In scenario 1, which reflects the case that the true dose-toxicity is aligned with prior means, 
54.5% of the simulated trials declared a dose as MTD with true DLT rate in the targeted dose 
range. However, the starting dose 0.2 mg already has a DLT rate of 0.102. This contributes to 
the high percentage (32.4%) of all simulated trials for which the trial is stopped since none of

the doses is considered tolerable anymore. This is similar for scenario 2, where the DLT rate at 
the starting dose is 0.1, which leads to a high percentage of prematurely stopped trials (38.2%). 
But for a high-toxicity scenario, this is an expected situation.
Scenario 3 (low-toxicity scenario) shows, that even with small toxicity rates the model declares 
MTDs with true DLT rate in the targeted interval in a high percentage of trials (61.4%). 
Nevertheless, more patients are needed in this scenario. Since none of the pre-defined dose 
levels has a true DLT rate in the overdose range, only very few trials are stopped prematurely.
In both scenarios 4 and 5, more than 50% of the simulated trials declared a dose as MTD with 
true DLT rate in the targeted dose range.
The mean patient numbers range from 17.25 (scenario 1) to 33.59 (low-toxicity scenario) and 
the maximum number of patients in one trial was 60. Therefore the patient numbers are as 
expected and decrease when moving away from the low-toxicity scenario.
In summary, the considered data scenarios show a reasonable behaviour of the model and the 
operating characteristics demonstrate a good precision of MTD determination.
Since dose escalation for Schedule B is conducted after the dose escalation for Schedule A, the 
initial mixture prior used for Schedule A dose escalation will be updated using the observed 
safety data on Schedule A to derive a meta-analytic predictive (MAP) prior for the BLRM of 
Schedule B. Two MAP priors are derived with one using the observed DLT in each dose of 
Schedule A and the other one using the observed DLT and with the doses in Schedule A being 
increased by 1.5 times to derive a corresponding dose in Schedule B which gives the same total 
dose in each 21-day treatment cycle. These 2 MAP priors are used with equal weight in the 
updated mixture prior of the BLRM for Schedule B dose escalation in the assessment of new 
hypothetical data scenarios. The details of these simulation analyses will be provided in the 
minutes of the regular DMC meetings.
Observed data in both schedule dose escalations will be used to update the prior used in the 
BLRM for patients with DLBCL with the selected schedule.
Statistical Appendix for Schedule C
10.3.2
To determine the MTD for Schedule C in solid tumour, patients are entered sequentially into 
escalating dose cohorts. The dose escalation will be guided by a Bayesian 5-parameter logistic 
regression model with overdose control (R15-4233).
This logistic regression model is defined as follows. Let π1, d1 be the probability of having a 
DLT when giving dose d1 of BI 894999 maintenance dose as monotherapy, and π2, d2 the 
probability of having a DLT when giving dose d2 of the combination partner BI 894999 loading 
dose as monotherapy, respectively. A logistic regression is used to model the dose-toxicity 
relationship for each of these dosing approachs individually:
Maintenance dose:
logit(π1,d1) =log(α1) + β1log(d1/d1*)
Loading dose: logit(π2,d2) =log(α2) + β2log(d2/d2*)

001-MCS-40-106-RD-03 (11.0) / Saved on: 24 Jul 2014
Here, the doses d1* = 4 mg and d2* = 5 mg represent the reference doses for maintenance dose 
and loading dose, respectively. 
In order to account for a potential positive (higher toxicity than expected under independence) 
interaction between maintenance dose and loading dose, a dose-dependent interaction term 
0<η<∞ is introduced in the model by the following definition: odds(π12,d1,d2) = odds(π0
12,d1,d2) 
exp(η d1/d1* d2/d2*)
and π12,d1,d2 is used in the likelihood
rd1,d2 ~ Binomial(nd1,d2,π12,d1,d2)
where rd1,d2 denotes the random variable describing the observed number of DLTs in nd1,d2
patients at the dose combination d1, d2.
Since a Bayesian approach is applied, prior distributions f for each of the parameter vectors 
θ1=(log(α1),log(β1)), θ2=(log(α2),log(β2)) and for the interaction term η need to be specified.
An informative prior is used for maintenance dose using historical information from schedule 
A and B with two transformation methods.
The prior distribution for θ1 will be specified as a mixture of two bivariate normal distributions, 
f(θ1) = a1f1(θ1) + a2f2(θ1)
with
ai, i = 1, 2 the prior mixture weights (a1+ a2 = 1)
and
fi(θ1) = MVN(μi, Σi)
the multivariate normal distribution of the i-th component with mean vector μi and covariance 
matrix Σi, where 
Σ = 
	
,
 , ,		
 , ,		
	
,		

Mixture prior distributions have the advantage that they allow for specification of different 
logistic dose-toxicity curves, therefore making the prior more robust.
A minimally informative prior is used for loading dose:
The prior distributions for θ2 will be specified as mixtures of three multivariate normal 
distributions, i.e.
а(θ2) = a1f1(θ2) + a2f2(θ2) + a3f3(θ2)
with
ai, i = 1, 2, 3 the prior mixture weights (a1+ a2+ a3 = 1)
and
fi(θ2) = MVN(μi, Σi),
the multivariate normal distribution of the i-th component with mean vector μi and covariance 
matrix Σi, where 
Σ = 
	
,

Mixture prior distributions have the advantage that they allow for specification of different 
logistic dose-toxicity curves, therefore making the prior more robust.

A weakly informative lognormal prior distribution will be used for η.
The estimated probability π12,d1,d2 of a DLT at each dose combination d1, d2 from the model 
will be summarized using the following intervals:
Under toxicity: [0.00, 0.16)
Targeted toxicity: [0.16, 0.33)
Overtoxicity: [0.33, 1.00]
The BLRM-recommended dose combination for the next cohort is the level with the highest 
posterior probability of the DLT rate falling in the target interval [0.16, 0.33) among the dose 
combinations fulfilling the EWOC principle. Per EWOC it should be unlikely (<25% posterior 
probability) that the DLT rate at the dose combination will exceed 0.33. However, the 
maximum allowable dose increment for the subsequent cohort will be no more than 100% for 
each drug.
The MTD may be considered reached if one of the following criteria is fulfilled:
1.
The posterior probability of the true DLT rate in the target interval [0.16 – 0.33) of the 
MTD is above 0.50, OR
2. At least 12 patients have been treated in the trial, of which at least 6 at the MTD.
Prior derivation:
To determine the maintenance dose prior distribution for θ1 and θ2, a meta-analytic predictive 
(MAP) approach will be used. Exact details on the derivation of the prior distributions and on 
the evaluation of the model using hypothetical data scenarios and operating characteristics are 
provided in the statistical appendix, a brief description is given here. 
The following steps were used to derive the prior distributions for all parameters:
1.
Maintenance dose θ1: 
Toxicity information on schedule C from schedule A and B in Phase Ia will be 
incorporated in Table 10.3.2: 1 with two transformation methods separately, which are 
equal total dose transformation and equal daily dose transformation during MTD 
evaluation period. The meta-analytic-predictive prior was derived using the historical 
toxicity information, allowing for substantial between-trial heterogeneity.
2.
Loading dose θ2: 
(1)
A low-toxicity weakly informative prior was derived reflecting the case that the 
compound would be much less toxic than expected. For this prior component, it 
was assumed that the median DLT rate at the starting dose of 2.5 mg would 
equal 0.001, and the median DLT rate at the anticipated MTD of 5 mg would 
equal 0.01. These assumptions yield μ31 = (-4.60, 1.20), i.e. basically a flat 
curve. The standard deviations and correlations were set to σ31,11 = 2, σ31,22 = 1, 
therefore almost fixing the slope parameter to its mean. The correlation was set 
to 0, i.e. ρ31 = 0. The prior weight a3,1 for the third component was chosen as 
0.8.

(2)
A high-toxicity weakly informative prior was derived reflecting the case that the 
compound would be much more toxic than expected. For this prior component, 
it was assumed that the median DLT rate at the starting dose of 2.5 mg would 
equal 0.1, and the median DLT rate at the anticipated MTD of 5 mg would equal 
0.2. These assumptions yield μ12 = (-1.39, 0.16). The standard deviations and 
correlations were set identical to the weakly informative prior, i.e. σ21,11 = 2, 
σ21,22 = 1 and ρ21 = 0, respectively. The prior weight a2,1 for the second 
component was chosen as 0.1.
(3)
A weakly informative prior was derived reflecting the a priori assumption that 
the median DLT rate at the starting dose of 2.5 mg would equal 0.01, and the 
median DLT rate at the anticipated MTD of 5 mg would equal 0.1. This yields 
μ11 = (-2.20, 1.24). The standard deviations were set such that large uncertainty 
about the parameter means is reflected, and the correlation was set to 0, thus 
yielding σ11,11 = 2, σ11,22 = 1 and ρ11 = 0, respectively. The prior weight a1,1 for 
the first component was chosen as 0.1.
3.
Interaction term η: 
Based on the a priori assumption of positive interaction between the two compounds, a 
lognormal distribution with mean -2.30 and standard deviation 1 was chosen. At the 
starting dose combination, the corresponding 95% prior interval covers an up to 4 fold 
increase (or decrease) in the odds of a DLT over positive interaction.

A summary of the prior distributions is provided in Table 10.3.2: 2 and Table 10.3.2: 3. 
Additionally, the prior probabilities of DLTs at different dose combinations, as well as the 
corresponding probability of under-, targeted and overtoxicity, are shown in Table 10.3.2: 4. 
As can be seen from the tables, the prior medians of the DLT probabilities are in-line with the

prior medians derived from the weakly informative priors, and the uncertainty around the 
medians is large, showing the low amount of information these priors provide. This is also 
supported by the prior sample size, i.e. the information contained in the priors. This is 
approximately equal to 7.1 patients for the prior of the combination of loading dose and 
maintenance dose.

Statistical model assessment
The model was assessed using hypothetical data scenarios and simulated operating 
characteristics. Hypothetical data scenarios are shown in Table 10.3.2: 5 reflecting potential 
on-study data constellations and related escalation as allowed by the model. Operating 
characteristics are assessed an assumed under assumed true dose-toxicity scenarios (Table 
10.3.2: 6), and the probability of recommending a dose with true DLT rate in the target interval 
can be approximated via simulation (Table 10.3.2: 7). More details are the same with model 
assessment for Schedule A and Schedule B which can be found in Section 10.3.1.

Description of change
-1.2.2: Addition of the pre-clinical findings of 
potential drug inducing effect of BI 894999 on 
CYP3A4, 1A2 and 2C8 
- 3.3.2: precision in inclusion criterion 6 that 
women 
of 
childbearing 
potential 
using 
a 
contraceptive pill as a method of birth control 
need to add a barrier method 
- 4.2.2: potential drug inducing effect of BI 894999 
on CYP3A4, 1A2 and 2C8 with possible result of 
reduction of plasma concentrations of concurrent 
medications which are substrates of these CYP 
enzymes, including contraceptive pills and the 
potential resulting decrease of their effectiveness: 
caution added in 4.2.2.1 about the use of 
concomitant medication which are substrates, 
request for women of childbearing potential using 
a contraceptive pill to add a barrier method in 
section 4.2.2.3
- Appendix 10.6: Addition of non-exhaustive list of 
CYP 3A4,  2C8 and 1A2 substrates
Further to additional pre-clinical findings:
Addition of whole blood samples for HEXIM1 
gene expression analyses at 24h post-dose of BI 
894999 intake on Days 1 and 14 of Cycle 1 and 
deletion of all peripheral blood mononuclear cells 
(PBMC) samples for HEXIM1 protein expression

7.3.6, 10.2, 10.5  
Additional changes:
- Section 3.1: 
- If no patient from first cohort experiences a 
drug-related CTCAE grade ≥2, the dose may be 
increased from 0.2 mg to 1 mg in second cohort 
and if no patient from second cohort experiences 
a drug-related CTCAE grade ≥2, the dose may 
be increased from 1 mg to 5 mg in third cohort
- Extension to more patients in a cohort due to a 
drug-related CTCAE grade ≥2 will only apply if 
the AE happens in a single patient cohort
- Section 3.1.1
DMC membership is given in extenso in the DMC 
charter, apart from the protocol

The compliance calculation will be done by 
counting the number of tablets from each strength 
actually taken x100 divided by the number of 
tablets from each strength which should have 
been taken
- Section 5.3.6.1:
DLT definitions: last bullet: any drug-related 
adverse event preventing from taking his 
treatment according to the given schedule (more 
than 2 consecutive doses missed): this concerns 
the AEs except those described in the 4 previous 
bullets of DLTs definitions.
“Protocol-specified significant events”: this term 
is replaced by “AESIs”
Intensity of Adverse Events: “intensity” is 
replaced by “severity”
-
- Section 6.2.1:
For the medical history, the number of metastatic 
sites will not be requested anymore
- Section 8.4.1: the term “side effect” is replaced by 
“adverse reaction”
Rationale for change
New pre-clinical findings need to be provided to 
the investigators and patients to make them aware 
of potential drug-drug interactions, specifically in 
relation to the contraceptive pill if this is being 
taken by women of child-bearing potential. This 
amendment includes additional safety measures in 
women of childbearing potential to not only rely on 
contraceptive pills for contraception, but they have 
to also use a barrier method of contraception as 
well.
Further additional preclinical 
PK/Pharmacodynamics modelling work showed 
the dynamics of HEXIM 1 (as a 
pharmacodynamics marker) over a 24 hour period 
post-dosing.  Given this new data, adding an extra 
sampling time point at 24h post-dose (on Day 1 and 
Day 14) would help understand the dynamics of 
HEXIM 1 in patients. Since the PBMC sampling 
(for analysis of HEXIM 1 protein) is only 
performed at 24h post-dose, this does not provide

information about the dynamics of HEXIM 1 
induction over the 24h period post-dose,  the 
PBMC collection is therefore not considered to be  
of additional  value to the biomarkers analysis and 
is removed from the protocol.
Additional changes:
- Section 3.1: 
- Clarification for the escalation rules used from 
first to second cohort and from second to third 
cohort
- Clarification on which cohorts are concerned by 
addition of patients in case of drug-related 
CTCAE grade ≥ 2 and how many patients 
needed under BLRM, once a drug-related 
CTCAE grade ≥ 2 occurred in Cycle 1 
- Section 3.1.1:clarification where to find in-
extenso DMC membership 
- Section 4.3: clarification on the way to calculate 
the compliance due to the different possible tablet 
strengths 
- Section 5.3.6.1:
Clarification on DLT definitions to make sure 
there is common and same understanding for 
everyone
“Protocol-specified significant events” is a term 
that is not used anymore in the protocol and 
corresponds to the term “AESIs” used for this 
protocol.
Intensity of AE: as the CTCAE grading is a 
severity scale, the term “severity” is more 
appropriate.
-
- Section 6.2.1: as the metastatic sites are described, 
there is no need to have the number in addition for 
the study interpretation of results
- Section 8.4.1: as the drug is not yet marketed, 
there are not yet known side effects and the term 
“adverse reaction” is the appropriate term

Description of change
Changes across all these sections concern:
-
The addition of a second Schedule, 
Schedule B, of intermittent administration 
of trial medication (two weeks on, one 
week off in 3-week cycles) in solid tumours 
in order to also determine the MTD with 
this Schedule. The Schedule B dose finding 
will run in parallel to Schedule A in patients 
with solid tumours, starting from the 
highest dose tested in Schedule A in 
patients with solid tumours and considered 
safe to start with by the DMC
-
The Schedule A of continuous dosing of 
trial medication (in 3-week cycles) will be 
administered in patients with solid tumours 
in order to determine the MTD with this 
Schedule and, starting from this MTD 
minus one dose level, an additional cohort 
of NHL patients will be included with

Schedule A in order to determine the MTD 
in patients with NHL. Once the MTD is 
determined in this NHL cohort, the cohort 
will be further extended at MTD until a 
total of 15 up to 27 patients are included in 
the NHL cohort.
The addition of the NHL cohort also leads 
to the change from “advanced solid 
tumours” to a more global designation of 
“advanced malignancies” in the title of the 
study to include both solid tumours and 
hematologic malignancies of the NHL type.
-
Once the MTD is determined for both 
Schedules A and B in patients with solid 
tumours, the DMC will determine the best 
Schedule and the MTD cohort of the chosen 
Schedule will be further extended up to 12 
patients
These changes imply 
-
the introduction of specific Flow Charts for 
Schedule B with additional days of visits 
and additional PK and pharmacodynamics 
tests to be performed in Cycles 1 and 2
-
the addition of pre-clinical information on 
tests performed in lymphoma and the 
rationale to test this BET inhibitor in 
patients with Non-Hodgkin lymphoma as 
well
-
the addition of MTD determination for

optional collection of archival tumour tissue 
and/or fresh tumour biopsy at the time of response 
or benefit for additional analyses centred around 
but not limited to the MOA of BI 894999 and the 
molecular nature of the disease. Analyses will 
include both RNA and DNA analysis in an 
attempt to identify biomarkers of efficacy. In case 
tumour tissue is given, a mandatory 2-3 mL 
EDTA blood DNA sample will be obtained from 
those patients

screening and at steady state in Cycle 1 are now 
optional for the whole Phase Ia, including the 
extension cohort at MTD and remain mandatory 
for the phase Ib patients
Rationale for change
- Addition of a second Schedule with intermittent 
dosing: this was already foreseen as a possibility 
in the first version of the protocol in case of 
intolerability of the continuous dosing schedule. 
As 2 DLTs occurred in 2 patients treated at a dose 
of 5 mg which is lower than expected from pre-
clinical models, the DMC decided to also test in 
parallel an intermittent dosing schedule in an 
attempt to improve tolerability of BI 894999.
- Addition of a NHL cohort: additional pre-clinical 
investigations both in vitro and in vivo have 
shown activity in lymphoma, particularly NHL. 
Recent preliminary data of Phase I trials with 
other BET inhibitors have also reported promising 
results in patients with NHL. Both pre-clinical 
data with BI 894999 and clinical results from 
other BET inhibitors warrant further investigation 
with BI 894999 in patients with NHL.
Additional changes
- Synopsis and sections 5.1.2 and 5.1.3: according 
to BI standards, there should not be more than 10 
secondary endpoints and each PK endpoint is 
considered separately. For this reason, the 
secondary PK endpoints were limited with some 
PK parameters becoming further endpoints.

2.3, 5.3.3, 5.3.5, 6.2, 10.4, 10.5: 
Cardiac monitoring was adapted to balance the

5.1.2, 6.1, 7.1, 7.3.1, 7.3.2, 10.3: 
Since this study will serve for a go/no go decision 
in further development of BI 894999 in NHL 
patients, it is important that the patients in the NHL 
cohort in this study are treated with the Schedule 
selected by the DMC in order to determine the 
recommended phase II dose in this patient 
population in case of further development in this 
indication.
Other changes were incorporated to clarify or adapt 
the protocol, 
-
such as the exclusion criterion of recent 
myocardial infarction in NHL patients to 
reflect the same exclusion criterion than for 
patients with solid tumours
-
the availability of 2 mg tablets as confirmed 
with an amendment to the IMPD, already 
submitted
-
or the clarification of which period is 
considered for DLT in case more than two 
doses are missed.

Rationale for change
Restriction of the NHL to a DLBCL cohort will 
allow analyses of results in a more homogeneous 
patient population. RECIL 2017 was set up for 
lymphoma evaluation. It will be more specific than 
RECIST 1.1 for evaluation in DLBCL although 
easier to use than Cheson criteria.
The choice of the four types of solid tumours to test 
in Phase Ib is based on additional pre-clinical work.
Almost half of the mCRPC patients will only 
present with bone metastases, hence necessitating 
specific tumour assessments based on bone scans 
and PSA evaluation when RECIST 1.1 would not 
be useable because of absence of target lesions to 
follow-up.
The 
increase 
frequency 
of 
monitoring 
for 
coagulation parameters is based on observation of 
factor VII decrease with another BET inhibitor as 
this might be a class effect.
The analysis of the primary endpoint in Phase Ib 
will happen without waiting for last patient last 
visit to allow earlier decisions on further 
development based on these results.
The use of 2-stage BHM approach with futility 
analysis after 9 patients in each patient cohort of 
Phase Ib will allow closing a cohort earlier if no 
efficacy signals are seen and avoid unnecessary 
exposure of additional patients of the same patient 
population.

The upper compliance limit is now set at 100% 
because the patient must be reminded as soon as 
he/she would take more than requested per 
protocol.
The delay for controlling electrolytes abnormalities 
will avoid having to consider grade 3 drug related 
abnormalities as DLTs because no control was 
performed at 72 h to determine the duration of the 
grade 3.
Additional biomarkers’ testing has shown that 
FFPE biopsies are suitable for analyses, which is an 
easier 
handling 
of 
samples 
for 
shipments. 
Biomarkers analyses will follow the evolution of 
knowledge on BET inhibition mechanism of action.

Safety lab parameters in Flow Charts Schedule B 
and Sections 2.3, 3.1, 4.2.1, 5.3.3, 10.5.2.1, 
10.5.2.2:
-
Addition of measurement of coagulation 
parameters: aPTT, PT in seconds and INR 
on C1D8, day of tumour biopsy in C1 if 
different day than C1D8, on C1D14 and on 
Day 15 in C2, C3 and C4
-
glucose measurements must happen in 
fasting condition after an overnight fast
-
Addition of evaluation of coagulation 
factors II, V, VII and IX on C1D1 pre-dose, 
on C1D14 and on C2V1D1 in 20 patients. 
-
In case of thrombocytopenia of CTCAE

Change of tumour biopsy in C1 under 
treatment with BI 894999 from between 
Day 11 and Day 14 to between Day 8 and 
Day 11. Further change to between Day 3 
and Day 8 of C1 in case the tumour biopsy 
cannot happen in 5 of the 20 first patients 
because of abnormal coagulation and/or a 
platelet count below 50 000/mm3 on the day 
of tumour biopsy when performed between 
D8 and D11.
-
Need for coagulation parameters (aPTT, PT 
in sec and INR) to be within normal ranges 
on the day of biopsy for biopsy to be 
performed and no request for biopsies in 
patients with therapeutic level of INR due 
to treatment with vitamin K antagonist or a 
novel oral anticoagulant

Clarification in handling of a drug-related CTCAE 
grade 3 troponin increase is seen: interruption of 
study medication and additional cardiac testing to 
rule out a new emerging cardiotoxicity. If ruled 
out, the treatment may be resumed at a reduced 
dose (DLT rule). Intensified cardiac monitoring 
will be performed in these cases by evaluation of 
LVEF before the re-start of treatment and every 2 
cycles thereafter to detect any new impaired wall 
motility or an indisputable drop of LVEF 
(percentage points reduction of ≥10 from baseline 
value or drop of LVEF below 50%, corresponding 
to a CTCAE grade 2) which would lead to drug 
discontinuation. 
-
Addition of exclusion criterion of LVEF 
lower than 50%
Other changes:
-
Section 3.3.3.1: NC patients may have a 
performance status of 2 for inclusion and 
may have already been treated with another 
BET inhibitor prior to study entry.
-
Flow Charts in Schedule B, 10.5.1, 
10.5.2.2: suppression of mandatory bone 
aspirate and biopsy in DLBCL patients in 
screening in case of negative FDG-PET 
uptake in bone marrow and
during 
treatment, if a CR is seen.
Rationale for change
Safety lab parameters:
-
Additional 
coagulation 
measures 
and 
evaluation of coagulation factors II, V, VII 
and IX: decrease of coagulation factor VII 
has been described with other BET 
inhibitors. 
Monitoring 
of 
coagulation 
parameters in the 1367.1 study revealed that 
some 
patients 
present 
with 
mild 
prolongation of prothrombin time (PT) and 
increase in international normalized ratio 
(INR) on Day 14 of Cycle 1. The additional 
measures are taken to better characterize the 
possible influence of BI 894999 on 
coagulation
-
Hyperglycaemia has been described with 
other BET inhibitors. The fact to mandate 
fasting glucose measures after an overnight 
fast will allow to characterize a possible

influence of BI 894999 on the glycaemia
-
To prevent the risk of bleeding related to BI 
894999 induced thrombocytopenia, the 
protocol recommends a platelet transfusion 
for any platelet count below 20 000/mm3
Tumour biopsy:
Since the monitoring of coagulation parameters in 
the 1367.1 study revealed that some patients 
present with mild prolongation of prothrombin time 
(PT) and increase in international normalized ratio 
(INR) on Day 14 of Cycle 1 which is the time at 
which biopsy under treatment was foreseen, tumour 
biopsies will only be performed if the platelet count 
is above 50 000/mm3 without the support of a 
transfusion and coagulation parameters (aPTT, PT 
in sec and INR) are within normal limits on the day 
of the biopsy. The day of biopsy will be moved 
ahead between Day 8 and Day 11 at a time of 
Cycle 1 when platelet count has not reach yet the 
nadir under BI 894999 treatment 
To avoid the need for switching patients from a 
vitamin K antagonist treatment or novel oral 
anticoagulant to low molecular weight heparin for 
the performance of biopsies, patients under these 
oral anticoagulation therapies are not requested 
anymore to undergo tumour biopsies.
Clarification of significance of troponin CTCAE 
grade 3 considered as drug-related: CTCAE grade 
3 troponin increases were seen in several patients 
under 
BI 
894999 
without 
evidence 
of 
cardiotoxicity shown from additional cardiac 
evaluation performed in these patients and without 
any concomitant signs of myocardial infarction. 
The real significance of increased troponin in this 
patient population is not totally understood. For 
this reason, in patients showing a CTCAE grade 3 
troponin increase considered drug-related by the 
investigator, the drug intake will be interrupted as 
for any DLT until additional cardiac work-up can 
rule out emerging cardiotoxicity. In this case, the 
patient will be allowed to resume the treatment at a 
reduced dose after a new LVEF evaluation, to be 
repeated 
every 
two 
cycles 
thereafter, 
with 
instructions in case of significant drop of LVEF.

For this reason LVEF lower than 50% has been 
added as an exclusion criterion.
Suppression of mandatory bone aspirate and biopsy 
in DLBCL patients in screening and in case of CR 
was decided because the main objective of this 
phase I study is the characterization of the safety 
and not the efficacy. This will decrease the burden 
of examinations in DLBCL patients.

Extension of NC cohort up to 20 patients and 
allowance of NC patients ≥ 15 years of age at the 
time of consent, allowance of NC patients who are 
progressing under trial treatment to continue with 
the treatment if they derive clinical benefit and no 
other treatment option is available: NC is a very 
aggressive malignancy for which no standard of 
care has been established. As this rare disease is 
observed in adolescents and young adults, for this 
indication, the trial will allow inclusion of minor 
patients aged 15 years or more. Indeed, the dose, 
safety and metabolism in adolescents of ≥15 years

are expected to be similar to adults because body 
size is expected to be close to adults and organ 
maturation is expected to be completed. However, 
to confirm the hypothesis that safety is similar in 
adolescents and adults, a mandatory DMC meeting 
will take place after the first and second adolescent 
patient complete Cycle 1 to assess whether the 
adult dose is tolerable in adolescents. In this 
population the benefit is expected to outweigh the 
risks because there is no standard treatment 
available and BI 894999 is specifically targeting 
the NUT-BRD fusion that is characteristic for the 
disease. The trial will also be extended to the USA 
to help with the recruitment of NC patients.
NC patients will be allowed in the trial even if they 
have no measurable disease because PFS will also 
be an important point of efficacy evaluation in 
addition to RECIST evaluation in this rare and 
aggressive disease and to give a maximum of NC
patients the possibility to participate to the trial 
when no other treatment option is available.
Removal of the maximum treatment break period 
between two cycles and removal of the limitation 
of dose reduction to twice for a single patient: this 
is to avoid that a patient deriving clinical benefit 
from the drug would have to stop if an AE does not 
recover within 14 days or that a patient who still 
has drug related AEs necessitating a further dose 
reduction after having already had two would need 
to stop the trial drug while deriving benefit from it.
DMC meetings will also be held in an official way 
in the phase Ib to make sure there is close follow-
up on the global safety profile of the drug and 
decisions on further treatment of the patients in the 
trial are made by all principal investigators together 
with the BI trial staff.

The change of request of an overnight fast before 
drug intake is adapted further to the results from 
the

which showed that food intake before drug intake 
caused approximately 30% decrease in the extent 
of absorption. There was no or only very limited 
effect of food on the rate of absorption.

loading dose on Day 1 followed by a 
maintenance dose on the six next days and a 
week off, repeated every two weeks in 4-
week cycles
This implies a change in the total number of 
patients with 18 additional patients foreseen to 
reach and confirm MTD in Schedule C.
Schedule C recruitment will start in Belgium in 
the two sites participating since the beginning 
of the study in July 2015 and with priority in 
these sites to recruitment for Schedule C (with 
the possibility later on to extend to further 
Belgian sites if needed) and with priority in 
these sites to recruitment for Schedule C.
When a dose reduction is needed in Schedule C 
for a single patient, it will happen with a 
decrease by steps of 1 mg for the loading dose 
and 0.5 mg for the maintenance dose, each time

non-listed therapies as part of standard 
possible treatment, depending on the 
country where the patient is treated

cancer treatment after the REP on a separate page 
of follow-up therapy.
6.2.1: deletion of the request to record the date of 
progression after previous line(s) of therapy for 
advanced or metastatic disease.
Rationale for change 
-
Further to the results from modelling of 
toxicity observed on thrombocytes and 
results of PK and pharmacodynamics, an 
additional dose escalation will be performed 
with a Schedule C
-
As the protocol is now ongoing since July 
2015 and several changes were brought to 
the design, it will make the understanding 
easier for new readers on what was done 
and what is still ongoing, explaining the 
DMC decisions until now.
-
In DLBCL patients in need of a treatment, it 
is not always possible to wait until they 
reach a stable dose of corticosteroids for 
four weeks before treatment as the steroids 
are used to allow the transition between 
previous treatment and the trial treatment.
-
It was unclear in the previous versions of 
the protocol how many EDTA DNA 
samples had to be performed for a single 
patient and when.
-
For some patients, it may be difficult to 
obtain a second tumour biopsy a few weeks 
after the first one if there is no easily 
accessible lesion and the difficulty to obtain 
a second biopsy should not prevent patients 
in need for an experimental treatment from 
entering the trial
-
Overnight hospitalization on the intensive 
PK periods is not mandatory if not deemed 
necessary by the investigator and/or not 
deemed more convenient for the patient

If Schedule C appears to have a better 
tolerability profile than Schedule B in 
patients with solid tumours, NC patients 
may also better benefit from Schedule C

At the present time there is no recognized 
standard treatment for NC patients. The 
number of patients in this trial is extended 
for NC patients, being it in cohort of 
Schedule B or in cohort with Schedule C if

possible for patients to have the possibility 
to join a trial until opening of other trials in 
this indication.
-
Because NC patients may be entered in the 
trial without target lesions, there is a need to 
be able to evaluate the efficacy with other 
criteria than the RECIST 1.1 imaging. This 
is the reason for adding overall survival for 
NC patients. Also because patients may 
continue beyond progression if they derive 
clinical benefit, time to treatment failure 
was added to the PFS. Overall clinical 
benefit judged by the investigator is an 
indirect way of adding the quality of life 
dimension in this very ill patient population
-
Germany further evaluated the possibility of 
including adolescent patients without the 
radiation burden of imaging by CT scan. 
They agreed to include adolescent patients 
aged between 15 and < 18 at the condition 
that these patients would not undergo CT 
scans but only MRI imaging evaluations. In 
other countries, the choice of CT or MRI is 
left to the investigator for all patients but 
the same method is to be used along the 
study for a single patient
-
Inclusion criterion 12 of section 3.3.2: As 
there is no established effective treatment 
for NC patients, a newly diagnosed NC
patient can be included in the study if the 
investigator considers that the patient has 
no other treatment options.

Exclusion criteria 13 and 14: because NC 
patients are usually progressing fast and

The addition of MTD determination of Schedule C

overcome the toxicity mainly thrombocytopenia 
grade 4 seen with Schedule B higher doses and to
be able to increase the total dose given to these 
patients with less interruptions due to toxicity.

Schedule C in DLBCL patients, the MTD 
determination of Schedule C in patients with solid 
tumours and the decision of DMC to open the NC 
cohort to Schedule C while closing the Schedule B 
cohort. These updates are also reflected in the use 
of past tense for parts of the study already finished 
at this stage of protocol revision.
Section 3.3.2.1: inclusion criterion 2: in Germany
and in South Korea, only legally adult patients may 
be included in the trial.
Rationale for change 
The COVID-19 pandemic requires adaptations to 
the benefit-risk evaluation for ongoing and new 
patients in the trial with additional guidance to 
ensure patient’s safety by decreasing in-patients 
visits to the sites if needed and by giving 
instructions in case a patient is tested positive to 
SARS-CoV-2.
Changes for the DLBCL and NC patients of 
Schedule C: decrease in the number of visits and in 
the number of PK and biomarkers samples is done 
to lighten the burden of the trial for these heavily ill 
patients. The allowance for some visits to be 
performed remotely by the investigator for these 
patients after all tests having been done locally is 
also to decrease the number of travels to the 
minimum acceptable according to the individual
benefit-risk
evaluation 
as 
judged 
by 
the 
Investigator in the post-COVID-19 situation with 
possible travel restrictions. For the same reason, the 
protocol version 12.0 allows the possibility to 
dispense the drug for two consecutive cycles 
starting from Cycle 5 onwards if the patient is 
tolerating the drug well or to have a direct shipment
