GLOSSARY OF TERMS 
Assessment 
A procedure used to generate data required by the study 
Cycles 
Number and timing or recommended repetitions of therapy are usually 
expressed as number of days (e.g.: q28 days) 
Dose level 
The dose of drug given to the patient (total daily or weekly etc.) 
Enrollment 
Point/time of patient entry into the study; the point at which informed 
consent must be obtained (i.e. prior to starting any of the procedures 
described in the protocol) 
Investigational drug 
The study treatment whose properties are being tested in the study; this 
definition is consistent with US CFR 21 Section 312.3 and is synonymous 
with “investigational new drug.” 
Investigational treatment 
Drug whose properties are being tested in the study as well as their 
associated placebo and active treatment controls (when applicable). This 
also includes approved drugs used outside of their indication/approved 
dosage, or that are tested in a fixed combination. Investigational treatment 
generally does not include other study treatments administered as 
concomitant background therapy required or allowed by the protocol when 
used in within approved indication/dosage 
Patient Number 
A unique identifying number assigned to each patient/subject/healthy 
volunteer who enrolls in the study 
Period 
A subdivision of the study timeline; divides stages into smaller functional 
segments such as screening, baseline, titration, washout, etc. 
Premature patient withdrawal Point/time when the patient exits from the study prior to the planned 
completion of all study treatment administration and/or assessments; at this 
time all study treatment administration is discontinued and no further 
assessments are planned, unless the patient will be followed for progression 
and/or survival. 
Stage related to study timeline A major subdivision of the study timeline; begins and ends with major 
study milestones such as enrollment, randomization, completion of 
treatment, etc. 
Stage in cancer 
The extent of a cancer in the body. Staging is usually based on the size of 
the tumor, whether lymph nodes contain cancer, and whether the cancer has 
spread from the original site to other parts of the body. 
Stop study participation 
Point/time at which the patient came in for a final evaluation visit or when 
study treatment was discontinued whichever is later. 
Study treatment 
Includes any drug or combination of drugs in any study arm administered to 
the patient (subject) as part of the required study procedures, including 
placebo and active drug run-ins. 
In specific examples, it is important to judge investigational treatment 
component relationship relative to a study treatment combination; study 
treatment in this case refers to the investigational and noninvestigational 
treatments in combination. 
Study treatment 
discontinuation 
Point/time when patient permanently stops taking study treatment for any 
reason; may or may not also be the point/time of premature patient 
withdrawal 
Supportive treatment 
Refers to any treatment required by the exposure to a study treatment, e.g. 
premedication of vitamin supplementation and corticosteroid for 
pemetrexed disodium. 
Variable 
Identifier used in the data analysis; derived directly or indirectly from data 
collected using specified assessments at specified time points.

AMENDMENT 5 (15-JAN-2020) 
Amendment rationale 
 
The primary purpose of this amendment is to: 
 
• Revise based on updates to standards for safety and study conduct for BGJ398. 
• Add second interim analysis. 
Changes to the protocol 
 
Changes to specific sections of the protocol are shown in the track changes version of the 
protocol using strikethrough for deletions and underlines for insertions. 
 
• Title page: Updated the Medical Monitor from 
MD, to 
MD; updated protocol version history. 
 
• Investigator’s Agreement: Added statement of purpose for signature. 
• Synopsis, Purpose and Rationale; Section 1.2.1; Section 2.2: Corrected “pan-FGFR 
inhibitor” to “FGFR 1-3 inhibitor” (with corresponding data, in Section 1.2.1.1). 
 
• Synopsis, Population; Section 2.2; Section 4.1: Clarified number of patients with and 
without FGFR2 gene fusions or translocations in Cohort 1. 
 
• Synopsis, Main Inclusion Criteria; Section 5.2 (inclusion criteria 2 and 3); 
Section 7.1; Section 7.2.4: Clarified requirements for determination of FGFR gene 
alterations. 
 
• Synopsis, Main Inclusion Criteria; Section 5.2 (inclusion criteria 4 and 5); 
Sections 14.3.3, 14.3.14, and 14.3.15 (Appendix 3): Removed “or evaluable” from 
disease criteria. 
 
• Synopsis, Main Exclusion Criteria; Section 5.3 (exclusion criterion 5): Removed 
“corneal abrasion” as a disqualifying disorder; other edits for consistency. 
 
• Synopsis, Investigational and reference therapy; Section 1.2.1: Defined BGJ398 as

AMENDMENT 4 (24-APR-2019) 
Amendment rationale 
 
The primary purpose of this amendment is to: 
 
• Revise assessment of overall response for the primary endpoint for patients with 
FGFR2 gene fusions or translocations from confirmation by investigator to 
confirmation by independent central confirmation (according to FDA advice), and 
change investigator assessment of overall response from a primary to a secondary 
objective. 
 
• Include an interim analysis, occurring when the patients enrolled prior to 
amendment 2 have potentially been followed up for at least 10 months after their 
initial exposure to study treatment. 
 
• Revise the RECIST criteria guidelines (Appendix 3, Section 14.3) to be consistent 
with published criteria. 
 
• Include 2 additional cohorts, allowing enrollment of patients with known FGFR1, 2, 
or 3 activating mutation or FGFR1 or 3 fusions or translocations (Cohort 2; 
20 patients) and patients with FGFR2 gene fusions or translocations after previous 
treatment with gemcitabine-containing regimen followed by progression on an FGFR 
inhibitor (excluding BGJ398) (Cohort 3; 10 or 20 patients). Rationale is provided in 
Section 2.2. 
 
• Include an interim analysis for Cohort 3 when the first 10 patients who receive study 
treatment have the potential to complete their second scheduled scan; this analysis is 
to determine if an additional 10 patients will be added to the cohort. 
 
• Clarify that 108 patients with FGFR2 gene fusions or translocations will be included 
in Cohort 1, and this sample size is the basis of statistical analyses for this group. 
 
• Allow another formulation of BGJ398 (ie, final market image version 4, or FMI IV) 
to be administered to patients, with accompanying pharmacokinetic analysis and 
analysis comparing the 3 formulations administered in the study. 
 
• Extend follow-up for survival from one year to 5 years after discontinuation of study 
treatment or until patients have died, withdrawn consent, or been lost to follow-up. 
 
• Exclude patients with history and/or current evidence of extensive tissue calcification 
of the vascular system (according to FDA advice). 
 
• Modify criteria for interruption and re-initiation of BGJ398 treatment (Table 5) in 
accordance with QTc evaluation plan submitted to FDA and for consistency with 
other ongoing studies of BGJ398.

AMENDMENT 2 (24-JAN-2017) 
Amendment rationale 
 
The primary purpose of this amendment is to: 
 
1. Increase enrollment to approximately 120 patients in order to 1) introduce a new drug 
formulation, Final market image version 3 (FMIv3) and 2) allow further evaluation of 
the safety and preliminary efficacy signal observed in the first 61 patients enrolled. 
Enrollment will be restricted to those patients with intrahepatic cholangiocarcinoma 
whose tumors have FGFR2 gene fusions/translocations; patients with other FGFR 
genetic alterations will not be enrolled. The increased sample size will permit more 
precise estimation of response rate, duration of response and progression free 
survival. 
 
Of the 61 patients enrolled to the BGJ398X2204 study (30-Jun-2016), there were 58 
patients evaluable for preliminary assessment of efficacy (with valid baseline and at 
least one valid post-baseline assessment). In these 58 patients, the investigator- 
assessed ORR (confirmed responses only) is 15.5%. Disease control rate is 79.3% (46 
patients). Additionally, out of the 37 patients who achieved stable disease, 6 patients 
achieved PR in one scan (did not have subsequent scan confirming the PR). Of the 61 
patients, 39 (63.9%) had a PFS event (3 deaths and 36 patients progressed as per 
RECIST). The median PFS is estimated at 175 days (95% CI: 130 – 230 days). 
 
Final Market Image version 3 (FMIv3) will replace the current drug formulation 
(FMIv1) in the current study for all patients enrolled following the implementation of 
this protocol amendment. These two formulations have been previously compared in 
two separate studies [CBGJ398X2103 and CBGJ398X2106] to the clinical service 
form which was used to establish MTD of BGJ398 at 125 mg qd [CBGJ398X2101]. 
Cross-study comparison of the exposures (AUC and Cmax) between FMIv3 and 
FMIv1 indicated that exposure of BGJ398 from the FMIv3 formulation is about 21- 
35% higher than that of FMIv1 (21% for AUCinf, 29% for Cmax and 35% for AUClast). 
Although BGJ398 has demonstrated high interpatient variability in exposure at the 
125 mg dose, on average, steady-state concentrations provide target coverage over the 
dosing interval at doses associated with efficacy. As observed events with BGJ398 
are readily monitorable and considered manageable, patient’s doses can be 
individually titrated to maximize therapeutic potential and minimize toxicity across a 
wide exposure range. Thus, the dose of FMIv3 125 mg qd should pose no additional 
safety concerns. However, pharmacokinetics, safety and tolerability data from the 
first 20 patients treated with FMIv3 up to the end of cycle 1 of treatment will be 
assessed and compared with the historical data from patients treated with FMIv1. 
Serial blood samples will also be collected from the remaining patients in this study 
to further characterize the pharmacokinetic properties of FMIv3 in this patient 
population.

AMENDMENT 1 (11-MAR-2015) 
Amendment rationale 
 
The purpose of this amendment is as follows: 
 
• Inclusion/Exclusion criteria were modified to clarify patient eligibility and align with 
standard of care treatment practice for cholangiocarcinoma. 
 
• Hyperphosphatemia management guidelines were updated to provide more detail 
regarding the prophylaxis of hyperphosphatemia and how to modify BGJ398 dose 
administration in response to elevated serum phosphorous levels. 
 
• Serum creatinine and creatinine clearance exclusion criteria were revised to align 
with current medical practice and provide consistency across BGJ398 protocols. 
BGJ398 has not been demonstrated to be nephrotoxic. 
 
• Evaluations of cardiac function by echocardiogram/MUGA scan were added on day 1 
of cycles 2, 3 and 4 to monitor changes in left ventricular ejection fraction (LVEF) 
and make monitoring frequency consistent across BGJ398 protocols. Asymptomatic 
and reversible decreases in LVEF have been noted in patients treated with BGJ398. 
 
• The emergence of acquired resistance to therapy is a major problem for patients with 
cancer. Under this amendment, language has been inserted to allow the collection of 
tumor tissue at baseline and upon the development of acquired resistance to treatment 
as described in the optional companion sample collection protocol. The purpose of 
these samples and a sample of normal tissue to aid in the identification of somatic 
variants in the tumor is to identify genetic changes in the tumor that may underlie 
treatment resistance. Two blood samples are also collected to test the potential value 
of circulating cell free tumor DNA as a possible replacement in some circumstances 
for tumor biopsies. 
 
• Minor inconsistencies, edits, and typographical errors that were identified after the 
finalization of the original protocol have been corrected with this amendment. 
 
Changes to the protocol 
 
• Updated Protocol Summary to further clarify inclusion criteria regarding patient 
eligibility coming off a prior regimen due to toxicity

Study type 
Interventional 
Purpose and rationale 
This study is designed to evaluate the efficacy of the targeted, selective 
FGFR 1-3 inhibitor BGJ398 when administered as a single agent to patients 
with genetically selected advanced or metastatic cholangiocarcinoma 
through estimation of the overall response rate. 
Molecular characterization of these tumors at baseline and at the time of 
progression may allow for increased understanding of potential treatment 
combinations, as well as primary and acquired resistance mechanisms. 
Primary Objective 
(Cohort 1) 
To evaluate the efficacy of single agent BGJ398 in patients with advanced or 
metastatic cholangiocarcinoma with FGFR2 gene fusions or translocations or 
other FGFR genetic alterations as measured by overall response assessed by 
central imaging review according to RECIST v1.1. 
Secondary Objectives 
(Cohort 1 and Overall 
Study) 
Cohort 1: To further evaluate the efficacy of single agent BGJ398 as 
measured by overall response assessed by investigator; progression free 
survival, best overall response, disease control assessed by investigator and 
by central imaging review as per RECIST 1.1; and overall survival. 
Cohort 1: To characterize the safety and tolerability of single agent BGJ398 
by type, frequency, and severity of AEs and SAEs. 
Overall study: To determine selected trough and 2-hr or 4-hr plasma 
concentrations of BGJ398 and its metabolites. 
Overall study: To characterize the pharmacokinetic profile of BGJ398 FMI 
III and FMI IV formulations. 
Study design 
This is a multi-center, open label, single arm phase II study evaluating 
BGJ398 anti-tumor activity in advanced or metastatic cholangiocarcinoma 
patients with FGFR genetic alterations. Oral, monotherapy BGJ398 will be 
administered once daily for the first 3 weeks (21 days) of each 28-day cycle. 
Treatment period will begin on Cycle 1 Day 1 and will continue until disease 
progression, unacceptable toxicity, withdrawal of informed consent, or 
death. Patients will be evaluated for tumor response radiographically every 8 
weeks until disease progression or discontinuation from study using RECIST 
1.1 criteria. 
Population 
Adult patients with histologically or cytologically confirmed advanced or 
metastatic cholangiocarcinoma with FGFR2 gene fusions or translocations or 
other FGFR genetic alteration who have evidence of radiologic progression 
following a cisplatin-and gemcitabine-containing regimen for advanced 
disease or a gemcitabine-containing regimen for those who are considered 
intolerant to cisplatin will be enrolled. Up to approximately 160 adult 
patients over age 18, both male and female will be enrolled. Three cohorts of 
patients comprise the study population:

1 BACKGROUND 
1.1 
Overview of disease pathogenesis, epidemiology and current 
treatment 
 
Cholangiocarcinoma is a rare, heterogeneous malignancy which originates from the 
neoplastic transformation of cholangiocytes into intrahepatic, perihilar, or distal 
extrahepatic tumors (Alpini 2001). In the United States, approximately 3,000 patients are 
diagnosed with cholangiocarcinoma of both the intra- and extrahepatic biliary system 
annually. Cholangiocarcinoma is more prevalent in Asia and Middle East, mostly 
because of a common parasitic infection of the bile duct (American Cancer Society 
2012). Men are slightly more likely to develop cholangiocarcinoma, while incidence 
increases with age in both sexes (Patel 2002). 
 
Usually, cholangiocarcinomas are adenocarcinomas and have poor prognosis with limited 
treatment alternatives. This is partly due to the late onset of symptoms and relative 
resistance to the therapies currently available. Moreover, conventional chemotherapy and 
radiation therapy (RT) have not been shown to be effective in prolonging long-term 
survival. Photodynamic therapy combined with stenting has been reported to be effective 
as a palliative treatment; however, it is not curative (Sirica 2005). In April 2010, the 
ABC-02 trial was published, which was the first phase III randomized, controlled trial in 
this patient population where patients were randomly assigned to receive cisplatin plus 
gemcitabine or gemcitabine alone (Valle 2010). In this study, the combination of 
gemcitabine/cisplatin demonstrated improved progression-free survival (PFS) and overall 
survival (OS) compared to gemcitabine alone. The median overall survival was 11.7 
months in the cisplatin–gemcitabine group and 8.1 months in the gemcitabine group. The 
median progression-free survival was 8.0 months in the cisplatin–gemcitabine group and 
5.0 months in the gemcitabine-only group. Still, cholangiocarcinoma patients relapsing 
after first line therapy have few therapeutic options, and there is no established second 
line standard of care. Response rates to currently available therapy are in the single digits. 
 
The most recent guidelines regarding treatment of advanced biliary tract cancers, 
developed by the National Comprehensive Cancer Network (NCCN), recommend the use 
of gemcitabine, capecitabine, or 5-fluorouracil (5-FU), either as single agents or in 
combination with a platinum analog (oxaliplatin or cisplatin), or the combination of 
gemcitabine and capecitabine, with the combination of gemcitabine and cisplatin 
receiving a category 1 recommendation. None of these agents are FDA approved 
primarily for use in biliary tract cancers. Moreover, multi-agent chemotherapeutic 
approaches do not confer a durable benefit in patients with metastatic and/or relapsed 
disease, and fewer than 5% of patients survive 5 years after diagnosis of advanced 
disease. Thus, there is a real need to develop novel therapeutic strategies for 
cholangiocarcinoma based on exploiting select molecular targets that would significantly 
impact clinical outcomes. Molecular alterations implicated in the dysregulation of 
cholangiocarcinoma cell growth and survival, aberrant gene expression, and invasion and 
metastasis have been considered potential therapeutic targets (Sirica 2005).

Introduction to investigational treatment(s) and other study 
treatment(s) 
 
1.2.1 
Overview of BGJ398 
 
BGJ398 (infigratinib; also known as BBP-831 and infigratinib phosphate) is an orally 
bio-available, potent and selective and ATP-competitive inhibitor of fibroblast growth 
factor receptors (FGFRs) 1-3, which has demonstrated anti-tumor activity in preclinical, 
in vitro and in-vivo tumor models harboring FGFR genetic alterations. BGJ398 belongs 
to the pyrimidinyl aryl urea chemical class and its chemical name is 3-(2,6-dichloro-3,5- 
dimethoxyphenyl)-1-{6-[4-(4-ethylpiperazin-1-yl)phenylamino]-pyrimidin-4-yl}-1- 
methylurea phosphate (1:1). 
 
Please refer to the current Investigator’s Brochure for the most recent information on 
BGJ398. 
 
1.2.1.1 
Nonclinical experience 
 
At the cellular level, BGJ398 selectively inhibits the kinase activity of FGFR1, FGFR2, 
FGFR3, as measured by inhibition of receptor autophosphorylation with IC50 values of 
4 - 5 nM for FGFR1, FGFR2 and FGFR3. Infigratinib is less potent in inhibiting FGFR4, 
with an IC50 of 164 nM for FGFR4. 
 
Consistent with inhibition of FGFR autophosphorylation, BGJ398 inhibits FGFR 
downstream signaling and proliferation of human cancer cell lines harboring genetic 
alterations of the FGFRs. These include, among others, lung and breast cancer cell lines 
with FGFR1 gene amplification, gastric cancer with FGFR2 gene amplification, 
endometrial cancer with FGFR2 mutations and bladder cancer with FGFR3 mutations or 
FGFR3 translocations (Wesche 2011). In line with its cellular activity, BGJ398 shows 
anti-tumor activity in multiple models bearing FGFR genetic alterations (Guagnano 2012; 
Konecny 2013). 
 
1.2.1.1.1 
Animal drug metabolism and pharmacokinetics 
 
In all species tested, BGJ398 exhibited a high plasma CL (clearance) and a large Vss 
(Volume of distribution at steady state). The compound is highly bound to plasma 
proteins (~ 98%) but does not preferentially distribute to red blood cells. BGJ398 is 
widely distributed to tissues in the rat and has a high affinity to melanin containing 
tissues. In vitro hepatic systems metabolize BGJ398 predominantly to 2 
pharmacologically active metabolites: BHS697 and BQR917. Biotransformation of 
BGJ398 to both metabolites was observed in human hepatocyte cultures. The compound 
is a P-gp and BCRP substrate and also inhibits BCRP mediated transport with an IC50 
value of 0.21μM. In addition, in vitro data indicate that BGJ398 is primarily a CYP3A4 
substrate. 
 
BGJ398 is a potent reversible inhibitor of CYP3A4 (Ki 0.26μM). The compound also 
reversibly inhibits CYP2C9 and CYP2C19 with Ki of 6.09μM and 4.1μM, respectively 
and CYP2C8 with IC50 of 12μM. BGJ398 is also a time dependent inhibitor of CYP3A4

with a KI=37.3 μM and Kinact=0.0547 min -1. In addition, CQM157, a recently 
identified metabolite in circulating plasma from patients, is also shown to be an inhibitor 
of CYP2C8, CYP2C9 and CYP3A4 (IC50 less than 10 μM) and CYP2C19 (IC50 12 μM). 
CQM157 is also an inhibitor of transporters P-gp, BCRP, OATP1B1 and OATP1B3 (IC50 
less than 5 μM). 
 
1.2.1.1.2 
Safety pharmacology and toxicology 
 
BGJ398 showed no evidence of in vitro genotoxicity in Ames and chromosome 
aberration tests and no evidence of phototoxicity in a 3T3 photo-cytotoxicity test. In vitro 
safety pharmacology assessment of BGJ398 revealed a decrease in human Ether-à-go-go- 
related gene (hERG) channel activity with an IC50 of 2.0 μM (1121ng/ml). 
In vivo safety pharmacology studies in rats and dogs did not reveal any effects on central 
nervous or respiratory systems and on hemodynamic or electrocardiographic parameters, 
respectively. 
 
In repeated dose (oral gavage; up to 4-weeks) toxicity studies, BGJ398 did lead to 
increases in serum FGF23 and serum phosphorous associated with partially reversible 
ectopic mineralization (kidney, lung, vascular and digestive systems) along with largely 
reversible changes in renal function parameters and bone growth plate thickening / 
retention of the primary spongiosa in rats (≥ 10 mg/kg/day) and dogs (≥ 10 mg/kg/day). 
These effects were deemed to be on-target effects mediated by pharmacological 
inhibition of FGFR. 
 
In rats, corneal changes were found upon 4 weeks of BGJ398 treatment consisting of 
irreversible, slight bilateral opacity with dose-dependent incidence, as assessed by in vivo 
ophthalmology. The clinical/ophthalmoscopic finding was associated with reversible, 
diffuse epithelial keratopathy at the highest dose of 10 mg/kg. In the 2-week rat toxicity 
study, doses of 20 mg/kg/day did lead to vasculopathy associated with moribundity after 
6 administrations. 
 
In dog toxicity study, minimal, fully reversible retention of the primary spongiosa and 
minimal increase in mineralization in lung and kidney without observed functional 
impairment were observed.

1.2.1.2.1 
Clinical pharmacokinetics 
 
The pharmacokinetics (PK) of BGJ398 and active metabolites have been evaluated 
following single and repeat daily doses in the ongoing phase I study (CBGJ398X2101). 
At 5 and 10 mg/day, plasma concentrations were low and frequently below the lower 
limit of quantification. Plasma concentrations were consistently quantifiable starting at 
20 mg/day.

Following a single dose, median Tmax was approximately 3-4 hours. The mean AUC0-24 
on Day 1 increased approximately 9 fold from 20 to 150 mg. The mean terminal 
elimination half-life on Day 1(T1/2) was 3-7 hr. Despite the relatively short half-life on 
Day 1, accumulation was observed with daily dosing at doses ≥ 60 mg, likely due to auto- 
inhibition of CYP3A4 mediated clearance pathways. Mean accumulation ratio (Racc) 
ranged from 3 to 8 on Days 15 and 28. Since dose interruptions occurred frequently 
following continuous daily dosing of BGJ398, PK parameters on Day 28 should be 
viewed with caution. The interpatient variability was high for BGJ398. 
 
Concentration data from active metabolites BHS697 (desethyl metabolite) and BQR917 
(Noxide) was available across all cohorts. CQM157 (aniline metabolite) was analyzed in 
a few patients following Amendment 6 of the BGJ398X2101 clinical protocol. In most 
patients, BHS697 and BQR917 were measurable at levels of ~5-50%, and <15% of 
parent exposure, respectively. Mean exposures on Day 1 (N=8) for CQM157 relative to 
BGJ398 varied across patients (3% -300%). CQM157 (N=4) did not appear to 
accumulate on daily dosing, whereas accumulation was observed for BGJ398 and 
metabolites BHS697 and BQR917. 
 
In vitro studies indicated that infigratinib inhibits CYP3A4; therefore, a clinical drug- 
drug interaction study (QBGJ389-106) was conducted to assess the effects of multiple 
doses of infigratinib on midazolam (a sensitive CYP3A4 substrate). Midazolam exposure 
in terms of AUCinf and Cmax was minimally reduced (11% and 1%, respectively). For the 
active metabolite, 1-hydroxymidazolam, exposure increased by 19% and 26% for AUCinf 
and Cmax, respectively. Overall, these results indicate that infigratinib had a small effect 
on the metabolism of midazolam and can be considered a weak CYP3A4 inhibitor. As 
such, infigratinib is not expected to have a clinically relevant effect on drugs metabolized 
by CYP3A4. However, due to the weak inhibition, drugs that are CYP3A4 substrates and 
have a narrow therapeutic index should be co-administered with caution.

2 RATIONALE 
2.1 
Study rationale and purpose 
 
The growing understanding of the genetic alterations involved in the tumorigenesis of 
cholangiocarcinoma provides new therapeutic options for molecular targets. Among other 
genetic alterations, recurrent gene fusions involving the FGFRs are an important class of 
driver mutations in a number of tumor types, including cholangiocarcinoma. 
 
Recently, Wu (2013) reported 24 primary tumors or cell lines with FGFR1, FGFR2, or 
FGFR3 fusions among other targetable gene fusions. These FGFR fusions involve 
numerous protein partners with various functions, which maintain kinase activity after 
formation. The identified gene fusions expressed an FGFR family member as a 5’ or 3’ 
fusion partner with an intact kinase domain, thus suggesting that these may serve as 
potential actionable therapeutic targets via kinase inhibition. Cancer types harboring 
FGFR fusions were quite diverse and included cholangiocarcinoma (n=2), breast cancer

Amended Protocol Version 06 (15-Jan-2020)

(n=4), prostate cancer (n=1), thyroid cancer (n=1), lung squamous cell carcinoma (n=6), 
bladder cancer (n=5), oral cancer (n=1), head and neck squamous cell carcinoma (n=2), 
and glioblastoma (n=2). Two cholangiocarcinoma patients were reported to harbor 
FGFR2-BICC1 fusions. Cells harboring FGFR fusions showed enhanced sensitivity to 
the FGFR inhibitors PD173074 and pazopanib, suggesting that patients with cancer with 
FGFR fusions may benefit from targeted FGFR kinase inhibition (Wu 2013). 
 
In a second study (Arai 2013), two fusion kinase genes, FGFR2-AHCYL1 and FGFR2- 
BICC1 were identified in 2 of 8 cholangiocarcinoma tumor samples by massive-parallel 
whole transcriptome sequencing. Further, RT-PCR and Sanger sequencing analysis of 
102 cholangiocarcinoma specimens (66 intrahepatic cholangiocarcinoma (ICCs) and 36 
extrahepatic cholangiocarcinoma (ECCs) identified seven FGFR2-AHCYL1-positive and 
two FGFR2-BICC1-positive cases, which were identified as oncogenic in an NIH3T3 
transformation assay. Treatment with FGFR inhibitors, including BGJ398, reversed the 
transformed phenotype. In a third study (Jiao 2013), somatic mutations in FGFR2 were 
identified in 4 of 32 (12.5%) intrahepatic cholangiocarcinomas. Thus, FGFR fusions or 
activating mutations could potentially identify a subset of cholangiocarcinoma patients 
who would benefit from targeted FGFR kinase inhibition. 
 
The selective FGFR inhibitor BGJ398 has been shown to specifically inhibit proliferation 
of cancer cells with FGFR genetic alterations; BGJ398 did not alter cell growth in cells 
that did not express FGFR or FGFR was not altered. In vivo, BGJ398 significantly 
inhibited growth of tumors in a dose-dependent manner in various mouse and rat 
xenograft subcutaneous or orthotopic models. These include models of bladder cancer 
with FGFR3 chromosomal rearrangement or FGFR3 mutation (RT112, MGHU3), 
endometrial cancer with FGFR2 mutation (AN3CA), lung cancer with FGFR1 
amplification (NCI-H1581) and gastric cancer with FGFR2 amplification (SNU16). In 
addition, a cholangiocarcinoma patient harboring an FGFR2 gene fusion treated with 
BGJ398 on the BGJ398X2101 study experienced tumor shrinkage. 
 
Thus, on the basis of the activity of BGJ398 in a variety of cancer models harboring 
FGFR genetic alterations (Guagnano 2012), BGJ398 could be used to treat patients with 
cholangiocarcinoma whose tumors harbor FGFR genetic alterations, including the 
recently recognized oncogenic gene fusions. 
 
Based on these data, the current study will treat cholangiocarcinoma patients whose 
tumor have been found to harbor oncogenic FGFR2 fusions or other FGFR genetic 
alterations, which are likely to confer sensitivity to BGJ398. 
 
2.2 
Rationale for the study design 
 
There is no established second line therapy for cholangiocarcinoma that provides patients 
with meaningful clinical benefit. Response rates for non-targeted therapy in this patient 
population have routinely been in the single digits (Valle 2010). On the basis of the 
activity of BGJ398 in a variety of cancer models harboring FGFR genetic alterations 
(Guagnano 2012), including translocations, a robust anti-tumor activity of BGJ398 is 
expected in patients harboring FGFR2 gene fusions or translocations. Thus, a single arm

Amended Protocol Version 06 (15-Jan-2020)

39 
 
 
study evaluating response to BGJ398 and durability of response is an appropriate design 
in this patient population. 
 
This study is designed to evaluate efficacy of the targeted, selective FGFR 1-3 inhibitor 
BGJ398 when administered as a single agent to patients with genetically selected 
advanced or metastatic cholangiocarcinoma through estimation of the overall response 
rate and to gain further understanding of the role of FGFR genetic alterations including 
gene fusions in this rare patient population. In addition, molecular characterization of 
these tumors at baseline and at the time of progression may allow for increased 
understanding of potential treatment combinations, as well as primary and acquired 
resistance mechanisms. 
 
Cohort 1 will enroll approximately 120 patients with advanced or metastatic 
cholangiocarcinoma who have evidence of radiologic progression following a cisplatin- 
and gemcitabine-containing regimen for advanced disease or a gemcitabine-containing 
regimen for those who are considered intolerant to cisplatin. This cohort includes 
approximately 106 patients with FGFR2 gene fusions or translocations and 14 patients 
with FGFR genetic alterations other than FGFR2 gene fusions or translocations who were 
enrolled before amendment 2. 
 
Cohort 2 will enroll approximately 20 patients with advanced or metastatic 
cholangiocarcinoma with FGFR genetic alterations other than FGFR2 gene fusions or 
translocations (specifically FGFR1, 2, or 3 activating mutation or FGR1 or 3 fusions or 
translocations) who have evidence of radiologic progression following a cisplatin-and 
gemcitabine-containing regimen for advanced disease or a gemcitabine-containing 
regimen for those who are considered intolerant to cisplatin. While FGFR2 fusions are 
the predominant FGFR genomic alteration seen in cholangiocarcinoma, other FGFR 
alterations do occur. In Cohort 1, 14 patients were enrolled with non-FGFR2 fusions, 
including 7 with FGFR1, 2, or 3 amplifications and 7 with FGFR2 mutations. In the 
7 patients with FGFR2 mutations and response data, 6 (86%) had stable disease (based on 
central review). Patients such as these with other FGFR alterations have no targeted 
treatment options, and these preliminary results compare favorably with outcomes for 
current standard of care. Therefore, Cohort 2 will enroll patients with known FGFR1, 2, 
or 3 activating mutation (See Appendix 4 [Section 14.4] for details of allowed mutations) 
or FGFR1 or 3 fusions or translocations. 
 
Cohort 3 will enroll up to approximately 20 patients with advanced or metastatic 
cholangiocarcinoma with FGFR2 gene fusions or translocations after previous treatment 
with gemcitabine-containing regimen followed by progression on an FGFR inhibitor 
(excluding BGJ398). As multiple FGFR inhibitors (both selective and non-selective) 
have entered into clinical development, it is important to understand the clinical efficacy 
when compounds are used in sequence. Consideration of the diverse mechanisms of 
action and binding pocket interactions for FGFR inhibitors suggests that BGJ398 may 
have activity when used after other FGFR inhibitors (both selective and non-selective). 
The potential for activity of BGJ398 in this population with limited therapeutic options 
supports study of BGJ398 in patients after treatment with and progression on other FGFR 
inhibitors. Approximately 10 patients will initially be enrolled and an additional

10 patients will be added if ≥4 patients of the 10 are assessed to be benefiting from study 
treatment as defined in Section 10.8.2. 
 
2.3 
Rationale for dose and regimen selection 
 
Patients enrolled in all cohorts of this study will receive 125 mg qd of BGJ398 on a 3 
week on (21 day) /1 week off (7 day) schedule in 28-day cycles. This dose level and 
regimen is based on experiences from the CBGJ398X2101 trial. 
 
The MTD/RP2D from the CBGJ398X2101 study was identified as 125 mg administered 
once daily (qd) in continuous 28-day cycles. While dose levels of 100 mg qd and higher 
were tolerated by patients, the majority of the patients experienced reversible 
hyperphosphatemia, which led to study drug interruptions. An evaluation of the drug 
administration records for patients prior to receiving prophylactic phosphate-lowering 
therapy, indicated that the median time until first dose interruption was approximately 23 
days and the median duration of interruption was 7 days. This observation led to the 
introduction of an expansion arm in the ongoing CBGJ398X2101 study to evaluate the 
administration of 125 mg qd on a 3 week on (21 days) / 1 week off (7 days) schedule in 
28-day cycles. To date, the majority of patients enrolled in this arm have completed their 
first cycle of therapy without hyperphosphatemia induced dose interruptions, while 
maintaining anti-tumor activity. 
 
According to amendment 2, the final market image version 3 (FMI III) formulation of 
BGJ398 replaced FMI I. These two formulations have been previously compared in two 
separate studies [CBGJ398X2103 and CBGJ398X2106] to the clinical service form 
which was used to establish MTD of BGJ398 at 125 mg qd [CBGJ398X2101]. Cross- 
study comparison of the exposures (AUC and Cmax) between FMI III and FMI I indicated 
that exposure of BGJ398 from the FMI III formulation is about 21-35% higher than that 
of FMI I (21% for AUCinf, 29% for Cmax and 35% for AUClast). Although BGJ398 has 
demonstrated high interpatient variability in exposure at the 125 mg dose, on average, 
steady-state concentrations provide target coverage over the dosing interval at doses 
associated with efficacy. As observed events with BGJ398 are readily monitorable and 
considered manageable, patient’s doses can be individually titrated to maximize 
therapeutic potential and minimize toxicity across a wide exposure range. Thus, the dose 
of FMI III 125 mg qd should pose no additional safety concerns. However, 
pharmacokinetics, safety and tolerability data from the first 20 patients treated with FMI 
III up to the end of cycle 1 of treatment will be assessed and compared with the historical 
data from patients treated with FMI I. Upon review of the data, it may be decided to 
continue dosing all subsequent patients at 125mg or at a lower dose. All decisions will be 
made by the QED Therapeutics study team in conjunction with the Investigators. Serial 
blood samples will also be collected from the remaining patients in this study to further 
characterize the pharmacokinetic properties of FMI III in this patient population. 
 
According to amendment 4, the final market image version 4 (FMI IV) formulation of 
BGJ398 will be used for patients in Cohorts 2 and 3. Additionally, patients in Cohort 1 
will be transitioned for FMI IV when this formulation is available at the study site.

and 3 treated with FMI IV up to the end of cycle 1 of treatment will be assessed and 
compared with the historical data from patients treated with FMI III.

4 STUDY DESIGN 
4.1 
Description of study design 
 
This is a multi-center, open label, phase II study evaluating BGJ398 anti-tumor activity in 
advanced or metastatic cholangiocarcinoma patients with FGFR genetic alterations. All 
patients will receive BGJ398 once daily on a three week on (21 days), one week off 
(7 days) schedule in 28-day cycles. Up to approximately 160 patients in total will be 
enrolled on the study. 
 
The study has 3 cohorts. Cohort 1 will have approximately 120 patients with advanced or 
metastatic cholangiocarcinoma: 106 with FGFR2 gene fusions or translocations and 14 
with other FGFR genetic alterations enrolled under the original protocol and 
amendment 1. 
 
Cohort 2 will have approximately 20 patients with advanced or metastatic 
cholangiocarcinoma with specific FGFR genetic alterations (refer to Section 5.2). 
 
Cohort 3 will have up to approximately 20 patients with advanced or metastatic 
cholangiocarcinoma with FGFR2 gene fusions or translocations who have received a 
prior FGFR inhibitor excluding BGJ398 (infigratinib). Unlike Cohorts 1 and 2, patients 
are allowed to have previous treatment with an FGFR inhibitor (either selective 
[excluding BGJ398] or nonspecific), as long as the required washout of at least 5 half- 
lives is met. 
 
In order to assess the antitumor activity of BGJ398, patients in all cohorts will be 
evaluated for tumor response radiographically every 8 weeks until disease progression or 
discontinuation from study using RECIST 1.1 criteria.

Molecular pre-screening 
 
Documented evidence of FGFR2 gene fusions or translocations or other FGFR genetic 
alterations is required in order to begin study related screening procedures. In addition, 
the patient may have additional molecular testing performed on the provided tissue 
sample. 
 
• Evidence can be demonstrated by either locally available data (local laboratory or 
institution-designated sequencing facility) or through the submission of an archival or 
newly obtained tumor sample to a QED Therapeutics designated central laboratory 
for analysis. Tissue requirements are described in Section 7.1.1. 
 
• If local data is not available, the patient must sign the molecular prescreening consent 
to allow for the collection and/or submission of samples for local testing at an 
institution designated laboratory or sequencing facility or to the QED Therapeutics 
designated central laboratory for analysis. 
 
If local data or the results of the central analysis meet inclusion criteria, the patient can 
proceed with the screening procedures. 
 
Screening 
 
Screening assessments must be completed within 21 days prior to the first dose of study 
treatment except for the radiological tumor assessment which should be performed within 
28 days prior to the first dose (Section 7.1.2). 
 
Treatment period 
 
Treatment period will begin on Cycle 1 Day 1 and will continue until disease 
progression, unacceptable toxicity, withdrawal of informed consent, or death 
(Section 7.1.3). 
 
End of treatment (EOT) 
 
The EOT visit occurs within 14 days after of the decision to discontinue study treatment 
(Section 7.1.4). All participating patients must complete this visit even if they had to 
discontinue prematurely. 
 
Follow-up 
 
All patients will be followed up as described in Section 7.1.6. 
 
30-day safety follow-up period 
 
At a minimum, all patients must complete the safety follow-up assessments 30 days after 
their last dose of BGJ398 (Section 7.1.6).

Disease progression follow-up period 
 
All patients enrolled in the study who discontinue study treatment for any reason other 
than disease progression will have a tumor assessment every 8 weeks, until disease 
progression or the initiation of subsequent anticancer therapies, or death, whichever 
occurs first. 
 
Survival follow-up period 
 
All patients enrolled in the study will be followed for survival at least every 4 months for 
up to 5 years after discontinuation of treatment (Section 7.1.6). 
 
4.2 
Timing of interim analyses and design adaptations 
 
Safety and efficacy data will be continuously monitored by QED Therapeutics in 
conjunction with the investigators for decision-making purposes. 
 
For Cohort 1, one analysis was performed before amendment 2 based on the 61 patients 
enrolled in the study (30 Jun 2016). Protocol amendment 2 restricted enrollment to 
patients with FGFR2 fusions or translocations, and the formulation was changed from 
FMI I to FMI III. 
 
After 20 patients had been treated with FMI III (for at least one cycle) based on 
amendment 2, a comprehensive review of all relevant data such as PK, safety, dose 
interruptions/reductions, and available efficacy was performed. Upon review of the data, 
it was decided to continue dosing all subsequent patients treated with FMI III at 125mg 
on a 3 weeks on, 1 week off schedule. 
 
In addition, two formal interim analyses for Cohort 1 are planned after amendment 3: 
 
• The first was conducted when the patients enrolled prior to amendment 2 and the 
patients in Cohort 1 with planned extensive PK sample collection (regardless of 
whether extensive PK samples were actually collected) had been followed up for at 
least 10 months after their initial exposure to BGJ398. 
 
• The second will be conducted when all the patients who received BGJ398 at the time 
of the first formal interim analysis have at least 10 months follow-up after their initial 
exposure to BGJ398. 
 
Additionally, for Cohorts 2 and 3, review of data will be performed after a total of 
15 patients in either Cohort 2 or 3 have been treated with FMI IV for at least one cycle. A 
formal interim analysis will be conducted for Cohort 3 when the first 10 patients who 
receive study treatment have the potential to complete their second scheduled scan; this 
analysis is to determine if an additional 10 patients will be added to the cohort (see 
Section 10.8.2).

Patients may have tumor tissue and blood samples collected at baseline and at disease 
progression to study the mechanisms of drug treatment resistance. 
 
4.4 
Definition of end of the study 
 
End of study is defined as the time when the last patient completes the survival follow-up 
as described in Section 7.1.6 and/or when the study is terminated early. 
 
4.5 
Early study termination 
 
The study can be terminated at any time for any reason by QED Therapeutics. Should this 
be necessary, the patient should make every effort to complete their final visit. The same 
assessments should be performed as described in Section 7.1.4 and Section 7.1.5 for a 
prematurely withdrawn patient. The investigator may be informed of additional 
procedures to be followed in order to ensure that adequate consideration is given to the 
protection of the patient’s interests. The investigator will be responsible for informing 
IRBs and/or ECs of the early termination of the trial. 
 
5 POPULATION 
5.1 
Patient population 
 
Adult patients with histologically or cytologically confirmed advanced or metastatic 
cholangiocarcinoma with FGFR2 gene fusions or translocations or other FGFR genetic 
alterations will be enrolled. Patients must have received at least one prior regimen 
containing gemcitabine with or without cisplatin for advanced/metastatic disease. Patients 
should have had evidence of progressive disease following their prior regimen or if prior 
treatment was discontinued due to toxicity must have continued evidence of measurable 
disease. 
 
Evidence of FGFR2 gene fusion or other FGFR genetic alterations must be documented 
through either institutional data or central laboratory testing (please refer to Section 7.1.1 
for further details). 
 
Patients enrolled in this study are not permitted to participate in additional parallel 
investigational drug or device studies. Patients who do not initially meet all of the 
inclusion or exclusion criteria may be re-screened for consideration in the trial. If a 
patient is rescreened, the same patient ID number should be used (see Section 7.1.2.2). 
 
Only patients who have documented evidence of FGFR2 gene fusion or other FGFR 
genetic alterations will be allowed to enter screening. The investigator or designee must 
ensure that only patients who meet all the following inclusion and none of the exclusion 
criteria are offered treatment in the study.

6.1.1.1 
Instructions for administration of BGJ398 
 
• Patients should be instructed to take the daily dose of BGJ398 in the morning, at 
approximately the same time each day (24 ± 4 hour interval). Patients will take their 
first dose of infigratinib at the study center on Cycle 1 Day 1. On the days of PK 
sampling, patients should not take their study drug dose at home; patients should take 
their study drug with them to the investigative site where administration of BGJ398 
will be supervised and administration time recorded. On PK sampling days after 
Cycle 1 Day 1, the time of the previous infigratinib administration (ie, the prior day) 
before the pre-dose PK sample will be recorded in the eCRF. Administration may fall 
outside of the ±4 hour interval on the days of PK sampling. 
 
• Patients who initiate treatment as of the implementation of amendment 2 will begin 
treatment using the FMI III form of BGJ398; patients enrolled into Cohorts 2 and 3 
under amendment 4 will receive the FMI IV form of BGJ398. Patients who started 
treatment prior to the implementation of amendment 2 should continue to receive the 
formulation of BGJ398 that they received at the initiation of treatment until FMI IV is 
available at the study site. At that time all patients on study will receive FMI IV. 
 
• BGJ398 should be administered in the fasted state at least 1 hour before or 2 hours 
after a meal. 
 
• BGJ398 should be taken with a large glass of water (~250 mL) and consumed over as 
short a time as possible. Patients should be instructed to swallow the capsules whole 
and not chew them. 
 
• If the patient forgets to take the scheduled dose in the morning (other than on a day of 
PK sampling), he/she should not take the dose more than 4 hours after the usual time 
and should continue treatment the next day. Any such doses that are missed should be 
skipped altogether and should not be replaced or made up at the next scheduled 
dosing. 
 
• If vomiting occurs following the dosing of study drug, re-dosing is not permitted that 
same day. Dosing should resume the next day. If the vomiting occurs on full PK 
sampling days within the first 4 hours post-dosing, this event needs to be noted on the 
dose administration PK eCRF page, as well as on the adverse event page, as 
appropriate. 
 
• BGJ398 is characterized by pH-dependent solubility, and therefore, medicinal 
products that alter the pH of the upper gastro-intestinal tract may alter the solubility 
of BGJ398, and limit bioavailability. These agents include, but are not limited to, 
proton pump inhibitors (eg, omeprazole), H2-antagonists (eg, ranitidine) and antacids. 
If possible, proton pump inhibitors should be avoided due to their long 
pharmacodynamic effect and replaced with H2-antagonists or antacids. BGJ398 
should be dosed at least 2 hours before or 10 hours after dosing with a gastric 
protection agent.

• Patients must avoid consuming grapefruits, grapefruit juice, grapefruit hybrids, 
pomegranates, star fruits, pomelos, Seville oranges, or products containing juice of 
these fruits, within 7 days prior to the first dose of study medication, through the end 
of study participation. This is due to a potential CYP3A4 interaction with study 
medication. Normal oranges and orange juice are allowed. 
 
• The investigator or responsible site personnel should instruct the patient to take the 
study drug exactly as prescribed to promote compliance. All dosages prescribed and 
dispensed to the patient and all dose changes or missed doses during the study must 
be recorded on the Dosage Administration Record eCRF. 
 
• Drug accountability must be performed on a regular basis. Patients will be instructed 
to return unused study drug to the site at the end of each cycle. The site personnel will 
ensure that the appropriate dose of each study drug is administered at each visit and 
will provide the patient with the correct amount of drug for subsequent dosing. 
 
6.1.2 
Ancillary treatments 
 
Phosphate-lowering treatment, including low phosphate diet and phosphate binding 
therapy such as sevelamer hydrochloride, should be implemented prophylactically with 
meals on the first day of study drug initiation and modified as clinically indicated 
throughout BGJ398 administration. Recommendations for treatment are provided in 
Table 5, but should be modified as per country or institutional guidelines. 
 
6.1.3 
Treatment duration 
 
All patients will receive BGJ398 daily on a three week on (21 days), one week off (7 
days) schedule in 28-day cycles. Patients may continue treatment with BGJ398 until the 
patient experiences unacceptable toxicity, disease progression, treatment is discontinued 
at the discretion of investigator or withdrawal of consent, or death. 
 
6.2 
Dose modifications 
 
6.2.1 
Dose modifications and dose delay 
 
For patients who do not tolerate the protocol-specified dosing schedule, dose adjustments 
are permitted in order to allow the patient to continue the study treatment. All dose 
modifications should be based on the worst preceding toxicity (Table 5, Table 6). Dosage 
changes must be recorded on the Dosage Administration Record CRF. 
 
The following guidelines should be applied. 
 
Each patient will be allowed 3 dose reductions according protocol-specified dose 
modifications for AEs. A QED medical monitor or designee approval is required for the 
third dose reduction (Table 4). 
 
Following resolution of toxicity to baseline or ≤ Grade 1, treatment is resumed at either 
the same or lower dose of study drug as per the criteria in Table 5. If treatment is 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020)

54 
 
 
resumed at the same dose of study drug, and the same toxicity recurs with the same or 
worse severity regardless of duration, dose must be reduced to the next lower dose level. 
If treatment is resumed at the lower dose of study drug, and the same toxicity recurs with 
the same or worse severity, the patient should have a second dose reduction. 
 
Patients who discontinue study treatment for a study related adverse event or an abnormal 
laboratory value must be followed as described in Section 6.2.2. 
 
Study drug must be permanently discontinued for a delay of >14 days and may only be 
restarted with written permission of a QED Therapeutics’ medical monitor if (1) the 
delay was not due to an AE that requires permanent study drug discontinuation as 
provided in Table 5, and (2) the patient has not met other criteria requiring study drug 
discontinuation in Section 7.1.4, and it is the Investigator’s opinion that no safety 
concerns are present.

6.2.2 
Follow-up for toxicities 
 
Patients whose treatment is interrupted or permanently discontinued due to an adverse 
event or clinically significant laboratory value, must be followed up at least once a week 
(or more frequently if required by institutional practices, or if clinically indicated) for 4 
weeks, and subsequently at 4-week intervals, until resolution or stabilization of the event, 
whichever comes first. Clinical experts or specialists, such as ophthalmologist, 
endocrinologist, dermatologist, should be consulted as deemed necessary. Further 
guidelines and dose modifications for the management of specific study drug induced 
toxicities (hyperphosphatemia, diarrhea) are provided in Table 5. All patients must be 
followed up for adverse events and serious adverse events for 30 days following the last 
doses of BGJ398. 
 
6.2.3 
Anticipated risks and safety concerns for the study drug 
 
Eligibility criteria as well as specific dose modification and stopping rules are included in 
this protocol. Guidelines for prophylactic or supportive treatment for expected toxicities, 
including management of study-drug induced adverse events, i.e. hyperphosphatemia, 
renal toxicities are provided in Table 5. Refer to nonclinical toxicity and or clinical data 
found in the BGJ398 Investigator’s Brochure. 
 
Treatment of adverse events or laboratory abnormalities should follow the protocol where 
specified. If not specified in the protocol, treatment of AEs or laboratory abnormalities 
should be according to local institutional guidelines. 
 
6.3 
Concomitant medications 
 
The patient must notify the investigational sites about any new medications he/she takes 
after the start of the study drug. All medications (other than study drug) and significant 
non-drug therapies (including physical therapy, herbal/natural medications and blood 
transfusions) administered during the study must be listed on the Concomitant 
Medications eCRF page. All cancer medications/therapies given to the patient after the 
last dose of study drug must be recorded in the eCRF Cancer Medications/Therapies page 
until patient is off study. A concomitant medication is considered prohibited if it appears 
on any of the prohibited medication lists for any clinical pharmacology property of the 
drug (e.g. CYP, BCRP). 
 
6.3.1 
Permitted concomitant therapy 
 
Any palliative and supportive care for disease related symptoms, including; any 
medication for a concurrent medical condition are permitted, except as specifically 
prohibited below. 
 
Hematopoietic growth factors 
 
Hematopoietic growth factors (e.g. erythropoietin, G-colony stimulating factor (CSF) and 
GM-CSF) are not to be administered prophylactically or to be used to meet eligibility

criteria. However, these drugs may be administered as per the label of these agents or as 
dictated by local practice or guidelines established by the American Society of Clinical 
Oncology (ASCO). 
 
Hormone replacement therapies 
 
Hormone replacement therapies such as thyroid and growth hormones are allowed, as 
well as estrogen replacement hormone treatment. 
 
Management of Hyperphosphatemia 
 
Hyperphosphatemia is a recognized on-target effect of potent and selective inhibitors of 
the FGFR pathway. While on BGJ398, patients should avoid foods that are especially 
high in phosphate and, if possible, should restrict dietary phosphate to 600 – 800 mg/day. 
High-phosphate foods include dairy products; meats, nuts, and other high-protein foods; 
processed foods; and dark colas. 
 
Patients who have experienced hyperphosphatemia should take a phosphate binder such 
as sevelamer, sucroferric oxyhydroxide, lanthanum carbonate, ferric citrate, etc. within 
30 minutes of a meal on the day while taking BGJ398. Once the patient has had 
hyperphosphatemia, the patient should remain on a low phosphate diet, if possible, and 
take phosphate binder on the days BGJ398 is taken, even if the serum phosphorus is 
normalized. Unless otherwise specified by the local package insert or institutional 
practice, the following regimen should be used to manage hyperphosphatemia: 
 
• For serum phosphorus >5.5 – 7.5 mg/dL 
○ Start sevelamer 800 mg three times a day with meals 
 
○ Increase the dose of sevelamer up to 1200 mg every 8 hours 
 
• For serum phosphorus ≥7.5 mg/dL 
○ Increase the dose of sevelamer up to 1600 mg (2 tablets per meal) every 8 hours 
 
○ Consider adding acetazolamide two to three 250 mg tablets per day. 
 
During the BGJ398 cycle, patients do not need to be on a low phosphate diet or take a 
phosphate binder during their 1-week off period unless serum phosphorus is not 
normalized. Other dose modifications are provided in Table 5, but should be modified as 
per country or institutional practice. 
 
Management of Diarrhea 
 
Patients should be instructed to notify their physician immediately at the first signs of 
poorly formed or loose stool or an increased frequency of bowel movements. 
Administration of antidiarrheal/anti-motility agents is recommended at the first sign of 
diarrhea as initial management. Some patients may require concomitant treatment with 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential

64 
 
more than one antidiarrheal agent. When therapy with antidiarrheal agents does not 
control the diarrhea to tolerable levels, study drug should be temporarily interrupted or 
dose reduced according to Table 5. 
 
Management of Bone Metastatic Disease 
 
Treatment of bone metastatic disease with symptomatic standard of care therapy 
according to institutional guidelines, including prophylactic treatment with 
bisphosphonates, palliative localized radiation therapy, and symptomatic treatment with 
steroids and pain medications is allowed. Initiation of other systemic anticancer therapy 
as described in Section 6.3.3 is not allowed and requires permanent discontinuation of 
study treatment. 
 
Management of Alopecia, Palmar-Plantar Erythrodysesthesia, Paronychia, 
and Stomatitis 
 
Recommendations for management (not required per protocol) of alopecia, palmar- 
plantar erythrodysesthesia syndrome, paronychia (adapted from Segaert 2005), and 
stomatitis (adapted from Rugo 2017) are provided in Table 6. These are guidelines only

6.3.2 
Permitted concomitant therapy requiring caution and/or action 
 
Details for specific medications which require action and/or caution while on study are 
provided in Appendix 1. The rationale for these medications is provided below. 
 
Drugs that alter the pH of the GI tract 
 
BGJ398 is characterized by pH-dependent solubility, and therefore, medicinal products 
that alter the pH of the upper gastro-intestinal tract may alter the solubility of BGJ398, 
and limit bioavailability. These agents include, but are not limited to, proton pump 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
Page 66
2 Protocol No. 
 
66 
 
inhibitors (eg, omeprazole), H2-antagonists (eg, ranitidine) and antacids. If possible, 
proton pump inhibitors should be avoided due to their long gastric pH-lowering effect 
and replaced with H2-antagonists or antacids. Study drug should be taken ≥2 hours before 
or 10 hours after dosing with an acid-reducing agent. 
 
Substrates and inhibitors 
 
CYP3A inhibitors and inducers 
 
BGJ398 is a substrate of CYP3A4. Therefore moderate inhibitors and inducers should be 
used with caution if no other alternative is available. If anticoagulation is required, 
heparin and/or low-molecular-weight heparins or direct thrombin inhibitors and/or Factor 
Xa inhibitors that are not metabolized by CYP3A4 (eg, dabigatran, edoxaban) are 
preferred. If unavoidable, anticoagulants that are CYP3A4 substrates and have a narrow 
therapeutic index (eg, warfarin sodium or any other coumadin-derivative anticoagulants 
or certain direct thrombin inhibitors [eg, argatroban] or Factor Xa inhibitors [eg, 
rivaroxaban]) should be used with caution. 
 
Transporter substrates 
 
In vitro data show that BGJ398 is an inhibitor of BCRP (Breast Cancer Resistance 
Protein). Medications which are BCRP substrates must be monitored for potential 
toxicity and may require dose titration or reduction of the medication. 
 
Anti-emetics 
 
Anti-emetics are allowed for the treatment of nausea or vomiting. It is recommended to 
avoid using drugs that are known to cause QT prolongation. Note that some anti-emetics 
have a known risk for Torsade de Pointes, and therefore need to be used with caution. 
See Appendix 1 for list of drugs that need to be used with caution. Aprepitant is both a 
sensitive substrate and a moderate CYP3A4 inhibitor and should be used with caution if 
an alternative is not available. 
 
Medications with a possible or conditional risk of QT/QTc interval 
prolongation or torsade de pointes 
 
Preliminary data have shown that BGJ398 has no effect on cardiac conduction or ECG 
intervals (see current version of the BGJ398 Investigator’s Brochure). However, 
medications that have the potential to prolong the QT/QTc interval or induce Torsade de 
Pointes (possible and conditional risk of TdP/QT prolongation) are allowed with caution. 
Investigators at their discretion may co-administer such medications, but patients should 
be carefully monitored. See Appendix 1 for list of drugs that need to be used with 
caution. Please note that the list might not be comprehensive. 
 
6.3.3 
Prohibited concomitant therapy 
 
Details for specific medications prohibited while on study are provided in Appendix 2. 
The rationale for the restricted medications is provided below. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
Page 67
2 Protocol No. 
 
67 
 
Other investigational and antineoplastic therapies 
 
Other investigational therapies must not be used while the patient is on the study 
treatment. Anticancer therapy (chemotherapy, biologic or radiation therapy, and surgery) 
other than the study treatment must not be given to patients while the patient is on the 
study medication. If such agents are required, then the patient must be discontinued from 
study treatment. The only exception is palliative localized radiation therapy for bone 
metastases with approval by QED Therapeutics’ medical monitor. 
 
CYP inhibitors 
 
Strong inhibitors of CYP3A4 such as the ones listed in Appendix 2 are prohibited 
because BGJ398 is a likely substrate of this isoenzyme. 
 
CYP inducers 
 
Strong inducers of CYP3A4 are prohibited because their usage may decrease the 
exposure of BGJ398. Therefore, agents such as those listed in Appendix 2 are prohibited. 
Please note that the list may not be exhaustive. 
 
Phosphorus and calcium 
 
Medications that increase the serum levels of phosphorus and/or calcium are prohibited. 
 
6.4 
Patient numbering, treatment assignment or randomization 
 
6.4.1 
Patient numbering 
 
Each patient is identified in the study by a Subject Number (Subject No.), that is assigned 
when the patient is first enrolled for screening and is retained as the primary identifier for 
the patient throughout his/her entire participation in the trial. The Subject No. consists of 
the Center Number (Center No.) (as assigned by QED Therapeutics to the investigative 
site) with a sequential patient number suffixed to it, so that each subject is numbered 
uniquely across the entire database. Upon signing the informed consent form, the patient 
is assigned to the next sequential Subject No. available to the investigator through the 
Oracle Clinical RDC interface. 
 
6.4.2 
Treatment assignment or randomization 
 
This is an open-label, single arm study. There will be no randomization required for this 
study. 
 
6.4.3

6.5.3 
Study drug compliance and accountability 
 
6.5.3.1 
Study drug compliance 
 
Compliance will be assessed by the investigator and/or study personnel at each patient 
visit and information provided by the patient and/or caregiver will be captured in the 
Drug Accountability Form. This information must be captured in the source document at 
each patient visit. 
 
On the day of a scheduled visit to the clinic, the patient will take the study drugs under 
the supervision of the Investigator or designee. The time of dose administrations on days 
when PK blood samples are drawn must be recorded in the Dosage Administration 
Record eCRF. 
 
6.5.3.2 
Study drug accountability 
 
The investigator or designee must maintain an accurate record of the shipment and 
dispensing of study treatment in a drug accountability log. Drug accountability will be 
noted by the field monitor during site visits and at the completion of the study. Patients 
will be asked to return all unused study treatment and packaging on a regular basis, at the 
end of the study or at the time of study treatment discontinuation. 
 
At study close-out, and, as appropriate during the course of the study, the investigator 
will provide access to all used and unused study treatment, packaging, drug labels, and a 
copy of the completed drug accountability log to the monitor.

into the database (D) or remain in source documents only (S) (“Category” column). 
 
Molecular pre-screening assessments can be done any time prior to the initiation of the 
screening. 
 
• Baseline imaging assessments can be conducted within 28 days prior to 1st day of 
study treatment. 
 
• All other baseline/screening assessments must be performed within 21 days prior to 
1st treatment, except for the ophthalmic examination, which should be completed 
within 14 days prior to first treatment. 
 
• Baseline/screening assessments that are conducted within 3 days prior to 1st treatment 
can be used to satisfy the day 1 requirement. Every effort must be made to follow the 
schedule outlined in Table 7. 
 
For all visits, there is a ± 3-day window on assessments to take into account scheduling 
over weekends and holidays, if not explicitly specified otherwise. For post baseline 
imaging and ophthalmic assessments, a ±7 day window is allowed, except for the first 
post baseline assessment (+7 day window permitted). There are no visit windows for the 
trough PK sampling days (sparse PK sample group [Table 10]: Cycle 1 Days 2, 8, 15, and 
21; and extensive PK sample group [Table 11]: Cycle 1 Days 2 and 16). 
 
PK samples will be collected according to Table 10 or Table 11. Biomarker sampling 
will be conducted as outlined in Table 12. 
 
All assessments should be performed as outlined in Table 7 and as clinically indicated.

a Screening assessments are to be completed within 21 days prior to the first dose of treatment, except for the radiological tumor assessment, which can be 
performed within 28 days prior to the first dose, and the ophthalmic examination, which should be completed within 14 days prior to first treatment. 
b Ophthalmic assessments for subsequent cycles (ie, after C3D1) are to be completed at C7D1 and every 4 months after that (ie, C11D1, C15D1, C19D1, etc). 
c Study drug will be administered in the clinic on the following days (PK sampling days): 
Sparse PK sample group (Table 10): C1D1,2,8,15,21; and C2-6 D1 and D15. 
Extensive PK group (Table 11): C1D1,2,15,16; and C2-6 D1. 
d If written documentation of FGFR2 gene fusion or translocation is determined by a pre-existing test or local laboratory, archival tumor tissue from the same 
biopsy sample used to determine eligibility (or a new tumor biopsy collected before BGJ398 treatment) should be submitted to the central laboratory for 
confirmation testing within 14 days after the first treatment. Refer to the Laboratory Manual for the sample requirements and processing instructions for central 
laboratory testing. 
e Sample will not be collected if a fresh tumor sample has already been collected at baseline for the purpose of DNA sequencing. 
f The first 20 patients enrolled in Cohort 1 and treated with FMI III and all patients enrolled in either Cohort 2 or Cohort 3 and treated with FMI IV (amendment 
4) will follow the extensive PK sampling schedule.

Protocol No. CBGJ398X2204 
 
74 
 
 
7.1.1 
Molecular pre-screening 
 
Evidence of genetic alterations, including FGFR2 gene fusion or other FGFR genetic 
alterations, can be obtained from pre-existing analysis, local testing of samples at an 
institution-designated laboratory or an institution-designated sequencing facility, or 
through the submission of samples to a QED Therapeutics designated laboratory central 
facility for testing. When possible, pre-existing analysis by local testing should be 
performed using a clinically validated test in a CLIA-certified (or equivalent) laboratory. 
 
If local or central testing will be conducted to determine the molecular status of the 
tumor, potential patients will be asked to sign a pre-screening informed consent to allow 
for the collection and analysis of the sample. A pre-screening consent form is not needed 
if the molecular status of the tumor was previously determined. Written documentation of 
the local FGFR2 test result must be present in the source documentation for review by 
QED Therapeutics. 
 
For central FGFR molecular testing, the archival or newly obtained tumor sample will be 
sent to a QED Therapeutics designated lab and the results of the analysis will be 
communicated to the respective center. Upon positive determination that the sample 
submitted contains the required FGFR2 gene fusions or translocation (Cohorts 1 and 3), 
or FGFR1, 2, or 3 activating mutation or FGFR1 or 3 fusions or translocations 
(Cohort 2), the patient may sign the study’s main Informed Consent to begin screening 
procedures. 
 
Additional testing will be performed to evaluate other genetic alterations related to or 
thought to be related to cholangiocarcinoma. 
 
A copy of the corresponding pathology report for each set of slides/blocks should be sent 
to QED Therapeutics designated central laboratory. 
 
FGFR translocation/alterations status must be captured on the appropriate eCRF upon 
enrollment onto the study after the patient has signed the study’s main Informed Consent. 
 
The tumor blocks will be returned, if molecular pre-screening inclusion criteria are not 
met. 
 
7.1.2 
Screening 
 
The IRB/IEC study approved informed consent form (ICF) must be signed and dated 
before any study-specific screening procedure is performed. Procedures which are part 
of the clinical routine during the initial diagnostic work-up of the patient may be obtained 
before obtaining the ICF. A copy of the ICF must be given to the patient or to the person 
signing the form. The investigator or designee must record the date when the study 
informed consent was signed in the medical records of the patient. 
 
Patients will be evaluated against study inclusion and exclusion criteria and safety 
assessments. For details of assessments, refer to Table 7. Screening assessments must be 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
75 
 
completed within 21 days prior to the first dose of treatment except for (1) the 
radiological tumor assessment, which should be performed within 28 days prior to the 
first dose, and (2) the ophthalmology examination, which should be completed within 
14 days prior to first dose. Screening assessments must be repeated if outside of 
screening windows. 
 
7.1.2.1 
Eligibility screening 
 
After a patient signs the study Informed Consent Form, the investigator or clinical site 
should determine patient eligibility. 
 
7.1.2.2 
Information to be collected for screen failures 
 
Patients who signed a molecular pre-screening ICF but are considered as ineligible after 
molecular screening, as well as patients who are found not eligible after signing the 
informed consent form to participate in the treatment phase of the study, will be 
considered as screening failures, and data will be handled in the same manner. The 
reason for not being started on study treatment will be entered on the screening phase 
disposition page. For all screening failure patients, demography, inclusion/exclusion and 
informed consent information along with the reason for screen failure will be collected. 
No other data will be entered in the database for patients who are screen failures, unless 
the patient experienced a Serious Adverse Event during the screening phase (see 
Section 8 for SAE reporting details). For molecular prescreening failures, only SAEs 
possibly related to a study procedure will be reported. 
 
7.1.2.3 
Patient demographics and other baseline characteristics 
 
Data to be collected will include general patient demographics, relevant medical history 
and current medical conditions, prior concomitant medications, diagnosis and extent of 
tumor, baseline tumor mutation status (FGFR gene fusions or translocation or other 
FGFR genetic alterations) and details on prior antineoplastic treatments. 
 
7.1.3 
Treatment period 
 
The treatment period commences on the first day of the first cycle of BGJ398 and ends 
after the last dose of BGJ398. 
 
During the study treatment period, patients will be regularly monitored to assess the 
safety and early anti-tumor activity of treatment. For purpose of scheduling and 
evaluations, a treatment cycle will consist of 28 days. 
 
During the treatment period, the patient is obliged to follow the investigators instructions 
with regards to contraception, concomitant medications and dosing regimen. There is no 
fixed duration; patients may continue treatment with the study drug until the development 
of an unacceptable toxicity that precludes any further treatment, disease progression, 
and/or treatment is discontinued at the discretion of the Investigator or by patient refusal. 
For details of assessments during the treatment period, refer to Table 7.

7.1.4 
Discontinuation of study treatment 
 
Patients may voluntarily discontinue from the study treatment for any reason at any time. 
If a patient decides to discontinue from the study treatment, the investigator should make 
a reasonable effort (e.g. telephone, e-mail, letter) to understand the primary reason for 
this decision and record this information in the patient’s chart and on the appropriate CRF 
pages. They may be considered withdrawn if they state an intention to withdraw, fail to 
return for visits, or become lost to follow-up for any other reason. 
 
Study treatment must be discontinued under the following circumstances: 
 
• Adverse events that lead to substantial changes in individual risk-benefit 
considerations 
 
• Dose delay of > 14 days from the intended day of the next scheduled dose, unless 
otherwise specified in Section 6.2.1, and approval by QED Therapeutics’ medical 
monitor 
 
• Pregnancy 
• Protocol deviation that results in a significant risk to the patient’s safety 
Patients who discontinue study treatment should NOT be considered withdrawn from the 
study. They should return for the assessments indicated in Table 7 (end of study 
treatment visit) and then enter the follow-up epoch. If they fail to return for these 
assessments for unknown reasons, every effort (e.g. telephone, email, letter) should be 
made to contact them as specified in Section 7.1.7 (Lost to follow-up). 
 
For patients who discontinue treatment for reasons other than documented disease 
progression, death, lost to follow-up, or withdrawal of consent, tumor assessments must 
continue to be performed every 8 weeks until documented disease progression, death, lost 
to follow-up, or withdrawal of consent. 
 
For patients who have documented radiographic disease progression and continue study 
treatment according to Section 6.2.1, no further imaging or transmittal of images for 
central imaging assessment is required. 
 
7.1.4.1 
Replacement policy 
 
No replacements will be needed. 
 
7.1.5 
Withdrawal of consent 
 
Patients may voluntarily withdraw consent to participate in the study for any reason at 
any time. Withdrawal of consent occurs only when a patient does not want to participate 
in the study any longer, and does not want any further visits or assessments, and does not 
want any further study related contact. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020)

QED Therapeutics will continue to retain and use all research results that have already 
been collected for the study evaluation. All biological samples that have already been 
collected may be retained and analyzed at a later date (or as required by local 
regulations). 
 
If a patient withdraws consent, the investigator must make every effort (e.g. dates of 
telephone calls, e-mail, letter) to determine the primary reason for this decision and 
record this information. 
 
Study treatment must be discontinued and no further assessments conducted. 
 
Further attempts to contact the patient are not allowed unless safety findings require 
communication or follow-up. 
 
7.1.6 
Follow-up period 
 
Patients lost to follow-up should be recorded as such on the eCRF. For patients who are 
lost to follow-up, the Investigator should show "due diligence" by documenting in the 
source documents steps taken to contact the patient, e.g. dates of telephone calls, 
registered letters, etc. 
 
30-day safety follow-up period 
 
All patients must complete the safety follow-up assessments 30 days after the last dose of 
the study treatment. Information relating to antineoplastic therapies taken since 
discontinuation of study treatment and AEs (including concomitant medication taken for 
ongoing AEs) will be collected for 30 days after the last dose of the study treatment. 
 
All AEs suspected to be related to study drug should be followed up weekly, or as 
clinically indicated, until resolution or stability (see also Section 6.2.2). 
 
Disease progression follow-up period 
 
All patients enrolled in the study who discontinue study treatment for any reason other 
than disease progression will have a tumor assessment every 8 weeks (± 7 days) as 
detailed in Table 7, until disease progression or the initiation of subsequent anticancer 
therapies, or death, whichever occurs first. Any newly started antineoplastic therapies 
during the follow-up period must be recorded on the Antineoplastic therapy since 
discontinuation eCRF. 
 
Survival follow-up period 
 
All patients enrolled in the study will be followed for survival at least every 4 months 
after discontinuation of treatment. Survival follow-up will continue for up to 5 years or 
until all patients have discontinued study treatment or have died, withdrawn consent, or 
been lost to follow-up.

7.1.7 
Lost to follow-up 
 
For patients whose status is unclear because they fail to appear for study visits without 
stating an intention to withdraw consent, the investigator should show "due diligence" by 
contacting the patient, family or family physician as agreed in the informed consent and 
by documenting in the source documents steps taken to contact the patient (e.g. dates of 
telephone calls, emails, letters, etc.). A patient should not be considered lost to follow-up 
until due diligence has been completed. 
 
7.2 
Assessment types 
 
7.2.1 
Efficacy assessment 
 
Tumor response will be evaluated locally by the investigator according to the guideline 
(see Appendix 3) based on the Response Evaluation Criteria in Solid Tumors (RECIST) 
Version 1.1 (Eisenhauer 2009). Each patient will be evaluated for all potential sites of 
tumor lesions at screening/baseline and every 8 weeks after starting study treatment until 
disease progression. 
 
CT (Computed Tomography) /MRI (Magnetic Resonance Imaging) scans will be 
performed at baseline within 28 days before start of treatment and subsequently every 8 
weeks from treatment start until progression of disease. 
 
After baseline, the first assessment should be performed at Cycle 3 Day 1 (+7 day 
window) and all subsequent assessments should be performed within ±7 days of the 
scheduled day of assessment. The same method of assessment and the same technique 
should be used to characterize each individual and reported lesion at baseline and during 
follow-up. If a patient discontinues treatment for reasons other than radiological 
documentation of progression of disease, an efficacy assessment should be performed at 
the time of End of Treatment unless a CT/MRI for tumor measurement was performed 
≤ 4 weeks earlier. 
 
Chest, abdomen, and pelvis CT scans are required for all patients at baseline. If at 
baseline, a patient is known to have a contraindication to CT i.v. contrast media or 
develops a contraindication during the trial, a contrast-enhanced MRI (if possible) of 
chest, abdomen, and pelvis should be performed. CT/MRI of the brain should be 
performed if clinically indicated. 
 
For the patients with skeletal lesions suspected at baseline, whole-body bone imaging 
should be obtained either with a TC99 bone scan or alternatively a NaF CT/ MRI PET 
scan. Of note, the CT or MRI portion of the scan should only be substituted for the 
required chest, abdomen, and pelvic CT scans if the CT or MRI is of diagnostic quality 
and meets all requirements as described in the study imaging guide (ie, oral and IV 
contrast, slice thickness, and anatomic coverage). Post-baseline, if skeletal lesions were 
identified at baseline, which are not visible on the chest, abdomen or pelvis CT/MRI 
scan, bone imaging with either a TC99 bone scan or NaF CT/MRI PET is required at all 
post-baseline imaging timepoints (every 8 weeks). In all cases that post-baseline bone 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
79 
 
imaging is required, the same modality that was used at screening should be used for all 
post-baseline imaging when possible. 
 
Partial Response (PR) and Complete Response (CR) should be confirmed by repeat 
assessments performed at least 4 weeks and no later than 6 weeks after the criteria for 
response are first met. 
 
PET/CT may be used only if it is of similar diagnostic quality as a CT performed without 
PET, including the utilization of oral and intravenous contrast media. While FDG-PET 
may complement CT scans in assessing progression per RECIST 1.1 (Appendix 3) FDG- 
PET assessments should be disregarded for this protocol. 
 
If possible, a single radiologist should perform all tumor response evaluations for an 
individual patient. 
 
Any lesion that has been previously treated with radiotherapy should be considered as a 
nontarget lesion. However, if a lesion previously treated with radiotherapy has clearly 
progressed since the radiotherapy, it can be considered as a target lesion. 
 
All radiological assessments obtained for patients enrolled in Cohort 1 will be sent to a 
QED Therapeutics designated central imaging CRO. The site manual provided by the 
designated imaging CRO will provide further details regarding image collection and 
central imaging assessment. 
 
7.2.2 
Safety and tolerability assessment 
 
Safety and tolerability assessments will include adverse event reporting and changes from 
baseline in laboratory parameters and vital signs. Tolerability will be assessed by the 
incidence of AEs leading to study drug delay or discontinuation. Safety will be monitored 
by assessing the procedures listed below as well as collecting of the adverse events at 
every visit. For details on AE collection and reporting, refer to Section 8. 
 
7.2.2.1 
Physical examination 
 
A complete physical examination must be performed as indicated in Table 7. 
 
Physical examination will be performed on the scheduled day, even if study treatment is 
being withheld. More frequent examinations may be performed at the discretion of the 
Investigator and if medically indicated. 
 
A complete physical examination will include the examination of general appearance, 
skin, neck (including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, 
lymph nodes, extremities, vascular and neurological. If indicated based on medical 
history and/or symptoms, rectal, external genitalia, breast, and pelvic exams will be 
performed. 
 
Information about the physical examination must be present in source documentation at 
the study site. Significant findings that are present prior to signing of informed consent 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential

80 
 
form for the study must be included in the Relevant Medical History/Current Medical 
Conditions page on the patient’s eCRF. Significant new findings that begin or worsen 
after informed consent for the study must be recorded on the AE eCRF. 
 
7.2.2.2 
Vital signs 
 
Vital signs (body temperature, pulse rate, blood pressure) must be performed in the same 
position, either sitting or supine, before dosing and as indicated in Table 7. 
Vital signs should be assessed on the scheduled day, even if study treatment is being 
withheld. More frequent examinations may be performed at the discretion of the 
Investigator and if medically indicated. 
 
7.2.2.3 
Height and weight 
 
Weight will be measured as indicated in Table 7. Height will be collected at screening 
only. More frequent examinations may be performed at the discretion of the Investigator 
and if medically indicated. 
 
7.2.2.4 
Performance status 
 
The ECOG performance status will be assessed as indicated in Table 8. Assessments of 
performance status will be performed on the scheduled day, even if study treatment is 
being withheld.

Electrocardiograms and cardiac imaging 
 
ECG evaluations will be conducted centrally. For all patients prior to the first 
administration of BGJ398, a minimum of 3 sequential 12-lead ECGs, separated by at 
least 5-10 minutes, must be performed on Day 1 of Cycle 1. This is necessary to get an 
accurate baseline QTcF calculation. 12-lead ECGs are to be performed at the following 
time-points: 
 
• At screening and/or baseline 
• Cycle 1 Day 1: pre-dose, 2-hr post-dose, ± 15 min, and 4-hr post-dose ± 30 min 
(3 sequential) 
 
• Cycle 1 Days 2, 8 and 15: pre-dose and 2-hr post-dose, ± 15 min (3 sequential) 
• Cycle 1 Day 15: 4-hr post-dose ± 30 min (3 sequential) 
• Cycle 2 onwards, day 1 of every cycle: pre-dose (3 sequential) 
• At the end of treatment 
MUGA scans or echocardiogram to assess LVEF will be performed as outlined in 
Table 7, within the windows outlined in Section 7.1. A MUGA scan or echocardiogram 
will be performed at end of study treatment only if an assessment of LVEF has not been 
performed ≤14 days prior to study completion. 
 
Clinically significant ECG and cardiac imaging findings must be discussed with the QED 
Therapeutics Medical Monitor prior to enrolling the patient in the study. Clinically 
significant ECG and cardiac imaging abnormalities present prior to randomization should 
be reported on the Medical History eCRF page. Significant new findings post

randomization from initiation of study drug until 30 days after permanent discontinuation 
of study drug must be recorded as an AE on the AE eCRF. 
 
7.2.3 
Pharmacokinetics 
 
Blood samples for PK evaluation will be collected from all enrolled patients participating 
in the study. Time points of blood sample collection for PK are outlined in Table 10 and 
Table 11. 
 
On the days of pharmacokinetic sampling, patients should take their medication at the 
clinic immediately after the pre-dose sample is taken. Patients who forget and take their 
medication at home will be excluded from pharmacokinetic analysis for that day; they 
should not have blood samples collected. Complete dosing information, including the 
date and time of actual blood draw and time of the last study drug dose prior to the 
sampling, should be obtained on all sampling days and recorded on the appropriate blood 
collection eCRF. If any of the scheduled sampling times are missed or a sample is not 
drawn according to this schedule, the actual collection date and time will be recorded and 
the remaining samples will be collected on schedule whenever possible. 
 
If vomiting occurs within 4 hours following study-drug administration on the day of PK 
blood sampling, the time (using the 24-h clock) of vomiting should be recorded. No 
additional trial medication should be taken in an effort to replace the material that has 
been vomited. The occurrence and frequency of any vomiting during a treatment cycle 
must be noted in the Adverse Events eCRF. If vomiting occurs after taking the drug no 
re-dosing of the patient is allowed before the next schedule dose. 
 
If any of the following events occurs, an unscheduled PK samples should be collected: 
 
• If a patient treated with investigational drug experiences an AE that results in an 
unscheduled visit or fits the criteria of a SAE, as determined by the investigator. 
 
• Whenever an ECG with a QTcF change from baseline > 60 ms or a new absolute 
QTcF ≥ 501ms result is known, an unscheduled blood samples should be collected to 
assess concentrations of BGJ398 and its metabolites. The exact time of sample 
collection should be noted in the eCRF. 
 
7.2.3.1 
Pharmacokinetic blood sample collection and handling 
 
At the specified time points detailed in Table 10 or Table 11, as appropriate, 3 mL of 
blood (per sample) will be collected for the measurement of plasma concentrations of 
BGJ398 and its metabolites. 
 
The first 20 patients enrolled in Cohort 1 and treated with FMI III, and all patients 
enrolled in Cohort 2 and Cohort 3 and treated with FMI IV, will follow the PK sampling 
schedule outlined in Table 11. 
 
All blood samples will be taken by central line, direct venipuncture, or an indwelling 
cannula inserted in a forearm vein. Complete instructions for sampling processing,

handling and shipment will be provided in the Laboratory Manual. Residual plasma 
samples from this study may also be used for exploratory analysis to further characterize 
the PK of BGJ398 and/or its metabolites. This may include using leftover samples for 
protein binding analysis or metabolite profiling (eg, other metabolites and markers for 
metabolic enzyme activity such as 4- beta hydroxyl cholesterol levels), if there is 
sufficient sample remaining.

and missing samples will be labeled accordingly. Study samples may be reanalyzed at 
other QED Therapeutics approved facilities for the determination of long term stability or 
cross-check between QED Therapeutics approved laboratories. These additional 
investigations are not considered part of this study and, as such, the results of any such 
analysis will not be included in the final report. 
 
7.2.4 
Biomarkers 
 
BGJ398 biomarker assessments are required to confirm patient eligibility and potentially 
aid in understanding the effects of BGJ398 treatment on molecular markers of disease 
and FGFR pathway regulation as related to clinical outcome. 
 
For all cohorts, written documentation of local laboratory or central laboratory 
determination of FGFR gene alterations from tissue collected before BGJ398 treatment is 
required. 
 
For Cohort 1 and Cohort 2: 
 
• If eligibility is determined by pre-existing test results or pre-screening by a local 
laboratory, then tumor tissue sample must be sent to the central laboratory for 
confirmation of the FGFR genetic alteration. The tumor tissue sent for confirmatory 
testing should be from the same biopsy sample that was used to determine eligibility. 
 
• If an archival tissue sample is not available, a new tumor biopsy must be obtained 
before BGJ398 treatment. Refer to the Laboratory Manual for additional details on 
the amount of tumor tissue required for testing by the central laboratory. 
 
• If written documentation of FGFR genetic alteration in tumor tissue is available from 
the central laboratory, an additional tumor sample does not need to be submitted for 
central molecular testing. 
 
For Cohort 3, written documentation of the FGFR2 gene fusion from a clinically- 
validated test on a sample (tumor tissue or cell-free DNA from blood) collected after 
treatment with the prior FGFR inhibitor is highly recommended. If written documentation 
is not available, a tumor sample collected after treatment with the prior FGFR inhibitor 
may be submitted to the central laboratory but is not required for enrollment. 
 
QED Therapeutics designated lab(s) will be used for processing of all tumor samples 
collected. The central laboratory will provide kits to collect and ship these samples to 
QED Therapeutics designated lab(s) for analysis. Details on the collections, shipment of 
samples are provided to investigators in the laboratory manual. 
 
While the goal of the biomarker assessments is to provide supportive data for the clinical 
study, there may be circumstances when a decision is made to stop a collection, or not 
perform or discontinue an analysis due to either practical or strategic reasons (eg, 
inadequate sample number, issues related to the quality of the sample or issues related to

the assay that preclude analysis, impossibility to perform correlative analyses, etc.). 
Therefore, depending on the results obtained during the study, sample collection analysis 
may be omitted at the discretion of QED Therapeutics.

Archived tumor samples 
 
Collection of an archival tumor sample (tissue blocks or 11-20 unstained slides) is 
mandatory and will be collected from all patients at screening if a sample was not 
submitted to the central laboratory for FGFR molecular prescreening. A corresponding 
pathology report should be included along with the archival sample. If an archival tumor 
sample is not available, a newly obtained tumor sample should be obtained and provided 
as a formalin-fixed, paraffin-embedded block. Archival or newly obtained tumor samples 
will be used to explore mechanisms of resistance to cancer treatment through analysis of 
next generation DNA sequencing data from tumor samples at baseline and after the

development of disease progression (whenever available). Additional archival sample 
may be requested if the original sample sent is of insufficient quantity or quality to 
complete the planned analysis. 
 
The sample collection must be captured on the appropriate eCRF and requisition page(s). 
Detailed instructions for the collection, handling, labeling, and shipment of samples are 
outlined in the CRO Laboratory Manuals. 
 
7.2.4.2 
Newly obtained tumor samples 
 
A newly obtained tumor sample should be collected at progression (end of treatment) for 
patients if safe and feasible, as it will provide a unique opportunity to investigate the 
potential mechanisms of resistance to BGJ398. This will be performed using a 
combination of genomic, transcriptomic and proteomic technology, which may include 
profiling of mutation, amplification and/or modification in DNA, RNA, or protein levels 
in tumor tissue. 
 
The sample collection must be captured on the appropriate eCRF and requisition page(s). 
Detailed instructions for the collection, handling, labeling, and shipment of samples are 
outlined in the CRO Laboratory Manuals. 
 
7.2.4.3 
Exploratory biomarkers- cell free DNA assessment 
 
Blood (approximately 10 ml) will be collected at screening, Cycle 2 Day 1, day 1 of 
every odd numbered cycle at the time of response assessment scans, and at the time of 
disease progression (EOT). These samples will be used for analysis of cell-free DNA to 
explore whether genetic alterations found in tumor samples may also be observed in 
blood, and if any alterations found are predictive of response and/or associated with 
development of resistance. 
 
Detailed instructions for the collection, handling and shipment of samples are outlined in 
the [CBGJ398X2204 Laboratory Manual]. 
 
7.2.4.4 
Optional additional exploratory biomarker assessments using the 
remaining biomarker samples 
 
Patients will have the opportunity to consent to use of their remaining samples (tissue, 
tumor DNA, or blood) for additional research related to BGJ398, cancer or other study 
treatments. This may also include research to help develop ways to detect, monitor or 
treat cancer. A decision to perform such exploratory biomarker research studies would be 
based on outcome data or from new scientific findings related to the drug class or disease, 
as well as reagent and assay availability. 
 
Remaining tissue and cell free DNA samples may be subjected to genetic testing (DNA, 
RNA, protein) to profile genetic alterations in these samples. The investigators and 
patients will not receive the results from future research. The biological samples will be 
coded with a unique number that links the samples to the study patient in the study 
database as part of de-identification of the samples.

The samples may be stored under QED Therapeutics’ control or by its authorized agents. 
The samples will be stored up to 15 years. The period of time that data derived from 
future research may be used is not specified and these data may be used indefinitely. The 
data may be shared with Health Authorities worldwide, at medical meetings, or in 
medical publications. Participation is optional for patients to have their tissue and blood 
used in future research. Patients can request that QED Therapeutics not use their stored 
samples for future research, to the extent that they have not already used the sample, and 
to the extent that they are able to locate the sample after it has been de-identified. Patients 
who fail prescreening or fail screening will not have their samples stored for future 
research. 
 
8 SAFETY MONITORING AND REPORTING 
8.1 
Adverse events 
 
8.1.1 
Definition and reporting 
 
An adverse event is defined as the appearance of (or worsening of any pre-existing) 
undesirable sign(s), symptom(s), or medical condition(s) that occur after patient’s signed 
informed consent has been obtained. (Adverse events that occur before a patient signs the 
informed consent are recorded on the Medical History/Current Medical Conditions 
eCRF.) Adverse events that occur after informed consent is signed and prior to initiation 
of study treatment will only be captured if they meet the definition of serious adverse 
events and are reported to be causally related with study procedures (eg, an invasive 
procedure such as biopsy). All other adverse events occurring after informed consent is 
signed prior to initiation of study treatment should be recorded as medical history. 
Adverse event monitoring and recording should be continued for at least 30 days 
following the last dose of study treatment. 
 
For patients who sign the molecular pre-screening ICF, AEs which occur after signature 
of this consent will only be captured if they meet the definition of serious as outlined in 
Section 8.2 and are reported to be causally related with study procedures (e.g. an invasive 
procedure such as biopsy). 
 
Patients with known FGFR2 gene fusions or other FGFR genetic alteration status will 
only sign the main study ICF and AE collection for these patients will start from the time 
of signing the main ICF. 
 
Adverse events (including lab abnormalities that constitute AEs) should be described 
using a diagnosis whenever possible, rather than individual underlying signs and 
symptoms. When a clear diagnosis cannot be identified, each sign or symptom should be 
reported as a separate Adverse Event. 
 
Adverse events will be assessed according to the Common Terminology Criteria for 
Adverse Events (CTCAE) version 4.03. If CTCAE grading does not exist for an adverse 
event, the severity of mild, moderate, severe, and life-threatening, corresponding to 
Grades 1 - 4, will be used. CTCAE Grade 5 (death) will not be used in this study. Rather, 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
90 
 
if the patient dies while on study, the death will be captured on the End of Treatment 
disposition eCRF. If the patient dies while in follow-up, the death will be captured on the 
End of Study disposition eCRF and if the patient dies post-follow-up and is being 
followed for survival, their death will be captured on the Survival Follow-up eCRF. 
The occurrence of adverse events should be sought by non-directive questioning of the 
patient during the screening process after signing informed consent and at each visit 
during the study. Adverse events also may be detected when they are volunteered by the 
patient during the screening process or between visits, or through physical examination, 
laboratory test, or other assessments. As far as possible, each adverse event should be 
evaluated to determine: 
 
1. The severity grade (CTCAE Grade 1-4) 
 
2. Its duration (start and end dates) 
 
3. Its relationship to study drug (reasonable possibility that AE is related: No, Yes) 
 
4. Action taken with respect to study treatment (none, dose adjusted, temporarily 
interrupted, permanently discontinued, unknown, not applicable) 
 
5. Whether medication or therapy was given (no concomitant medication/non-drug 
therapy given, concomitant medication/non-drug therapy given) 
 
6. Outcome (not recovered/not resolved, recovered/resolved, recovering/resolving, 
recovered/resolved with sequelae, fatal, unknown) 
 
7. Whether it is serious, where a Serious Adverse Event (SAE) is defined as in 
Section 8.2.1. 
 
Unlike routine safety assessments, SAEs are monitored continuously and have 
special reporting requirements; see Section 8.2. 
 
All adverse events should be treated appropriately. Such treatment may include changes 
in study drug treatment including possible interruption or discontinuation, starting or 
stopping concomitant treatments, changes in the frequency or nature of assessments, 
hospitalization, or any other medically required intervention. If a concomitant medication 
or non-drug therapy is given, this action should be recorded on the Adverse Event eCRF. 
 
Once an adverse event is detected, it should be followed until its resolution or until it is 
judged to be permanent, and assessment should be made at each visit (or more frequently, 
if necessary) of any changes in severity, the suspected relationship to the study treatment, 
the interventions required to treat it, and the outcome. 
 
Information about common side effects already known about the investigational drug can 
be found in the Investigator’s Brochure or will be communicated between IB updates in 
the form of Investigator Notifications. This information will be included in the patient 
informed consent and should be discussed with the patient during the study as needed.

Protocol No. CBGJ398X2204 
 
91 
 
8.1.1.1 
AE reporting of overdose of BGJ398 
 
Overdose of BGJ398 is to be reported as an AE when drug is administered or taken at a 
dose ≥200 mg and the overdose is associated with signs or symptoms. Overdose should 
follow the same reporting requirements as SAEs. 
 
8.1.1.2 
Hy’s Law 
 
Additionally, potential drug induced liver injury that meets the following criteria 
(elevation of bilirubin and ALT/AST that meet Hy’s Law criteria [FDA Guidance for 
Industry 2009]): 
 
• Treatment-emergent ALT or AST >3 × baseline value in combination with total 
bilirubin ≥2 × ULN (of which ≥35% is direct bilirubin) 
 
• Treatment-emergent ALT or AST >3 × baseline value in combination with clinical 
jaundice. 
 
and is suspected or confirmed drug-induced liver injury, according to Hy’s law criteria, 
requires reporting as an SAE. 
 
8.1.1.3 
Progression of underlying malignancy should be reported as AE 
only in special circumstances 
 
Progression of underlying malignancy is not reported as an adverse event if it is 
clearly consistent with the suspected progression of the underlying cancer as defined by 
RECIST criteria, or other criteria as determined by protocol. Hospitalization solely due to 
the progression of underlying malignancy should NOT be reported as a serious adverse 
event. Clinical symptoms of progression may be reported as adverse events if the 
symptom cannot be determined as exclusively due to the progression of the underlying 
malignancy or does not fit the expected pattern of progression for the disease under 
study. 
 
Symptomatic deterioration may occur in some patients. In this situation, progression is 
evident in the patient’s clinical symptoms, but is not supported by the tumor 
measurements. Or, the disease progression is so evident that the investigator may elect 
not to perform further disease assessments. In such cases, the determination of clinical 
progression is based on symptomatic deterioration. These determinations should be a rare 
exception as every effort should be made to document the objective progression of 
underlying malignancy. 
 
If there is any uncertainty about an adverse event being due only to the disease under 
study, it should be reported as an AE or SAE. 
 
8.1.2 
Laboratory test abnormality 
 
Abnormal laboratory values or test results occurring after informed consent constitute 
adverse events only if they induce clinical signs or symptoms, are considered clinically 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
92 
 
significant, require therapy (eg, hematologic abnormality that requires transfusion or 
hematological stem cell support), or require changes in study medication(s).Laboratory 
abnormalities that constitute an Adverse event in their own right should be recorded on 
the Adverse Events eCRF. Whenever possible, a diagnosis, rather than a symptom should 
be provided (e.g. anemia instead of low hemoglobin). Laboratory abnormalities that meet 
the criteria for Adverse Events should be followed until they have returned to normal or 
an adequate explanation of the abnormality is found. When an abnormal laboratory or test 
result corresponds to a sign/symptom of an already reported adverse event, it is not 
necessary to separately record the lab/test result as an additional event. 
 
Laboratory abnormalities, that do not meet the definition of an adverse event, should not 
be reported as adverse events. A Grade 3 or 4 event (severe) as per CTCAE v4.0 does not 
automatically indicate a SAE unless it meets the definition of serious as defined below 
and/or as per investigator’s discretion. A dose hold or medication for the lab abnormality 
may be required by the protocol and is still, by definition, an adverse event. 
 
8.2 
Serious adverse events 
 
8.2.1 
Definitions 
 
Serious adverse event (SAE) is defined as one of the following: 
 
• Is fatal or life-threatening 
• Results in persistent or significant disability/incapacity 
• Constitutes a congenital anomaly/birth defect 
• Is medically significant, ie, defined as an event that jeopardizes the patient or may 
require medical or surgical intervention to prevent one of the outcomes listed above 
 
• Requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for: 
 
a. Routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition 
 
b. Elective or pre-planned treatment for a pre-existing condition that is unrelated to 
the indication under study and has not worsened since signing the informed 
consent 
 
c. Treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission 
 
d. Social reasons and respite care in the absence of any deterioration in the patient’s 
general condition 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
93 
 
In addition, any suspected transmission of an infectious agent via a medicinal product 
will be considered an SAE at study centers in the EU. 
 
Progression of underlying malignancy is not reported as an adverse event if it is clearly 
consistent with the suspected progression of the underlying cancer as defined by RECIST 
criteria, or other criteria as determined by protocol. Hospitalization due solely to the 
progression of underlying malignancy should NOT be reported as a serious adverse 
event. 
 
Clinical symptoms of progression may be reported as adverse events if the symptom 
cannot be determined as exclusively due to the progression of the underlying malignancy 
or does not fit the expected pattern of progression for the disease under study. 
 
Symptomatic deterioration may occur in some patients. In this situation, progression is 
evident in the patient’s clinical symptoms, but is not supported by the tumor 
measurements. Or, the disease progression is so evident that the investigator may elect 
not to perform further disease assessments. In such cases, the determination of clinical 
progression is based on symptomatic deterioration. These determinations should be a rare 
exception as every effort should be made to document the objective progression of 
underlying malignancy. 
 
If there is any uncertainty about an adverse event being due only to the disease under 
study, it should be reported as an AE or SAE. 
 
8.2.2 
Reporting 
 
For patients whose FGFR2 gene fusions or other FGFR genetic alteration status is 
unknown, SAE collection will start upon signing the molecular pre-screening ICF. SAEs 
will only be reported if the event is suspected to be causally related to a study procedure 
as assessed by the investigator (e.g. an invasive procedure such as biopsy). SAEs will be 
followed until resolution or until clinically relevant improvement or stabilization. If the 
main ICF is not signed (molecular screen failure), SAE collection ends 30 days after the 
last study related procedure. If the main ICF is signed, SAE collection is as below. 
 
Patients with known FGFR2 gene fusions or translocations/other FGFR genetic alteration 
status who do not sign the molecular pre-screening ICF, SAE collection starts at the time 
of signing main study informed consent regardless of whether the patient is found to be a 
screen failure. 
 
To ensure patient safety, every SAE, regardless of suspected causality, occurring after 
the patient has provided informed consent and until at least 30 days after the patient has 
stopped study treatment must be reported to Covance Safety (email: 
SAEintake@covance.com; FAX: 1-888-726-8416) within 24 hours of learning of its 
occurrence. Any SAEs experienced after this 30 days period should only be reported to 
Covance Safety if the investigator suspects a causal relationship to the study treatment. 
Any additional information for the SAE including recurrent episodes, complications, or 
progression of the initial SAE must be reported as follow-up to the original episode 
within 24 hours of the investigator receiving the follow-up information. An SAE 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
94 
 
occurring at a different time interval or otherwise considered completely unrelated to a 
previously reported one should be reported separately as a new event. 
 
Information about all SAEs is collected and recorded on the Serious Adverse Event 
Report Form; all applicable sections of the form must be completed in order to provide a 
clinically thorough report. The investigator must assess and record the relationship of 
each SAE to each specific study treatment (if there is more than one study treatment), 
complete the SAE Report Form in English, and submit the completed form within 24 
hours to Covance Safety (email: SAEintake@covance.com; FAX: 1-888-726-8416). 
Detailed instructions regarding the submission process and requirements for signatures 
are to be found in the investigator folder provided to each site. 
 
Follow-up information is submitted in the same way as the original SAE Report. Each 
reoccurrence, complication, or progression of the original event should be reported as a 
follow-up to that event regardless of when it occurs. The follow-up information should 
describe whether the event has resolved or continues, if and how it was treated, whether 
the blind was broken or not, and whether the patient continued or withdrew from study 
participation. 
 
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the study treatment, a Covance Safety 
associate may urgently require further information from the investigator for Health 
Authority reporting. Covance Safety may need to issue an Investigator Notification (IN), 
to inform all investigators involved in any study with the same drug that this SAE has 
been reported. Suspected Unexpected Serious Adverse Reactions (SUSARs) will be 
collected and reported to the competent authorities and relevant ethics committees in 
accordance with Directive 2001/20/EC or as per national regulatory requirements in 
participating countries. 
 
8.3 
Emergency blinding of treatment assignment 
 
Not applicable. 
 
8.4 
Pregnancies 
 
To ensure patient safety, each pregnancy occurring while the patient is on study treatment 
(and for 30 days after the last study drug dose) must be reported to Covance Safety 
(email: SAEintake@covance.com; FAX: 1-888-726-8416) within 24 hours of learning of 
its occurrence. The pregnancy should be followed up to determine outcome, including 
spontaneous or voluntary termination, details of the birth, and the presence or absence of 
any birth defects, congenital abnormalities, or maternal and/or newborn complications. 
 
Pregnancy of a patient or partner of a male patient should be entered on the Pregnancy 
Notification CRF and reported by the investigator to Covance Safety (email: 
SAEintake@covance.com; FAX: +1-888-726-8416). Pregnancy follow-up should be 
documented on a paper Pregnancy Follow-up Form and reported to Covance Safety as 
above. Any SAE experienced during pregnancy must be reported on the SAE Report 
Form.

Pregnancy outcomes must be collected for the female partners of any males who took 
study treatment in this study. Consent to report information regarding these pregnancy 
outcomes should be obtained from the mother. 
 
8.5 
Warning and precautions 
 
No evidence available at the time of this writing indicated that special warnings or 
precautions were appropriate, other than those noted in the current Investigator’s 
Brochure. Additional safety information collected between IB updates will be 
communicated in the form of Investigator Notifications. This information will be 
included in the patient informed consent and should be discussed with the patient during 
the study as needed. 
 
8.6 
Data monitoring committee 
 
A Data Monitoring Committee (DMC) will not be in place for this trial: a DMC is 
considered not feasible due to the short duration of the study. However, measures are put 
in place for monitoring the safety of the patients participating in this part of the study: 
 
• Prompt review of safety data and constant monitoring for emerging safety signals by 
participating study sites and QED Therapeutics Personnel. As for any other study 
conducted by QED Therapeutics, any SUSAR and/or new safety signals will be 
promptly communicated to all participating investigators and Health Authorities. 
 
In lieu of a DMC, regular teleconferences with investigators will be held for reviewing 
reported safety data during the trial. 
 
8.7 
Steering committee 
 
Not applicable. 
 
9 DATA COLLECTION AND MANAGEMENT 
9.1 
Data confidentiality 
 
All records identifying the patient will be kept confidential and, in accordance with the 
applicable laws and/or regulations, will not be made publicly available. 
 
Patient names will not be supplied to the sponsor. Only the subject number will be 
recorded on the eCRF. If the patient name appears on any other document or trial 
materials, then that information must be redacted before a copy of the document is 
supplied to the sponsor. Trial data stored on a computer will be stored in accordance with 
local data protection laws and regulations. Patients will be informed in writing that 
representatives of the sponsor, Institutional Review Board/Independent Ethics 
Committee/Research Ethics Board (IRB/IEC/REB), or regulatory authorities may inspect 
their medical records to verify the information collected, and that all personal information 
made available for inspection will be handled in strictest confidence and in accordance 
with local data protection laws and regulations. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
96 
 
If the results of the trial are published, the patients’ identity will remain confidential. 
 
The investigator will maintain a list to enable patients’ records to be identified in 
accordance with applicable laws and regulations. 
 
The data collection system for this study uses built-in security features to encrypt all data 
for transmission in both directions, preventing unauthorized access to confidential 
participant information. Access to the system will be controlled by a sequence of 
individually assigned user identification codes and passwords, made available only to 
authorized personnel who have completed prerequisite training. 
 
Either year of birth or exact date of birth (depending on local privacy regulations) will be 
recorded to establish that the patient satisfies protocol age requirements and to enable 
appropriate age-related normal ranges to be used in assessing laboratory test results. 
 
9.2 
Site monitoring 
 
Before study initiation, at a site initiation visit or at an investigator’s meeting, QED 
Therapeutics personnel (or designated CRO) will review the protocol and CRFs with the 
investigators and their staff. During the study, the field monitor will visit the site 
regularly to check the completeness of patient records, the accuracy of entries on the 
CRFs, the adherence to the protocol and to Good Clinical Practice, the progress of 
enrollment, and to ensure that study treatment is being stored, dispensed, and accounted 
for according to specifications. Key study personnel must be available to assist the field 
monitor during these visits. 
 
The investigator must maintain source documents for each patient in the study, consisting 
of case and visit notes (hospital or clinic medical records) containing demographic and 
medical information, laboratory data, electrocardiograms, and the results of any other 
tests or assessments. All information recorded on CRFs must be traceable to source 
documents in the patient's file. The investigator must also keep the original signed 
informed consent form (a signed copy is given to the patient). 
 
The investigator must give the monitor access to all relevant source documents to 
confirm their consistency with the CRF entries. QED Therapeutics monitoring standards 
require full verification for the presence of informed consent, adherence to the 
inclusion/exclusion criteria and documentation of SAEs. Additional checks of the 
consistency of the source data with the CRFs are performed according to the study- 
specific monitoring plan. 
 
9.3 
Data collection 
 
The designated investigator staff will enter the data required by the protocol into the 
Electronic Case Report Forms (eCRF). The eCRFs have been built using fully validated 
secure web-enabled software that conforms to 21 CFR Part 11 requirements. the 
investigator and site staff will not be given access to the EDC system until they have been 
trained. Automatic validation programs check for data discrepancies in the eCRFs and, 
allow modification or verification of the entered data by the investigator staff. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
97 
 
The Principal Investigator is responsible for assuring that the data entered into eCRF is 
complete, accurate, and that entry and updates are performed in a timely manner. 
 
PK and biomarker (blood and tissue) samples obtained during the course of the study will 
be collected from the Investigator sites and analyzed by a QED Therapeutics designated 
laboratory, contracted central laboratories, or local laboratories. ECG data collected 
during the study will be reviewed and processed centrally by a specialist CRO. 
Designated investigational site staff will enter the information required by the protocol 
into the appropriate eCRF and/or designated laboratory requisition forms. Field monitors 
will review the eCRFs and laboratory paper requisition forms for accuracy and 
completeness and instruct site personnel to make any required corrections or additions. 
One copy of the requisition form will be forwarded to each analytical laboratory with the 
respective sample(s) by the field monitor or by the designated investigational site staff; 
and one copy will be retained at the investigational site. 
 
9.4 
Database management and quality control 
 
For studies using eCRFs, QED Therapeutics personnel (or designated CRO) will review 
the data entered by investigational staff for completeness and accuracy. Electronic data 
queries stating the nature of the problem and requesting clarification will be created for 
discrepancies and missing values and sent to the investigational site via the EDC system. 
Designated investigator site staff are required to respond promptly to queries and to make 
any necessary changes to the data. 
 
Concomitant treatments and prior medications entered into the database will be coded 
using the WHO Drug Reference List, which employs the Anatomical Therapeutic 
Chemical classification system. Medical history/current medical conditions and adverse 
events will be coded using the Medical dictionary for regulatory activities (MedDRA) 
terminology. 
 
PK, and biomarker samples and ECG data will be processed centrally and the results will 
be sent electronically to QED Therapeutics (or a designated CRO). 
 
The occurrence of any protocol violations will be determined. Once the data has been 
verified to be complete and accurate, the database will be declared locked and made 
available for data analysis. Appropriate QED authorization is required prior to making 
any database changes to locked data. 
 
After database lock, the investigator will receive a CD-ROM or paper copies of the 
patient data for archiving at the investigational site. 
 
10 STATISTICAL METHODS AND DATA ANALYSIS 
Data will be analyzed by QED Therapeutics and/or designated CRO. Any data analysis 
carried out independently by the investigator must be submitted to QED Therapeutics 
before publication or presentation.

It is planned that the data from participating centers in this protocol will be combined, so 
that an adequate number of patients will be available for analysis. Data will be 
summarized with respect to demographic and baseline characteristics, efficacy and safety 
observations and measurements and all relevant PK and PD measurements. Categorical 
data will be presented as frequencies and percentages. For continuous data, mean, 
standard deviation, median, 25th and 75th percentiles, minimum, and maximum will be 
presented. 
 
In general, analyses will be done by cohort with subanalyses by formulation (FMI I, III, 
or IV) or fusion status as appropriate unless otherwise specified. 
 
Two formal interim analyses for Cohort 1 are described in Section 10.7. The primary 
analysis for Cohort 1 will be conducted when all patients in Cohort 1 have the potential to 
be followed for at least 10 months after their initial exposure to study treatment. 
 
For Cohorts 2 and 3, review of data will be performed after a total of 15 patients in either 
Cohort 2 or 3 have been treated with FMI IV for at least one cycle. Primary analysis will 
be conducted when all patients in the cohorts have the potential to be followed for at least 
10 months after their initial exposure to study treatment. 
 
For Cohort 3, one formal interim analysis will be conducted after the first 10 dosed 
patients in this cohort have the potential to complete their second scheduled scans 
(approximately 16 weeks from their first dose) to determine if the cohort will be 
expanded. 
 
The additional data for patients continuing to receive BGJ398 and for patients who 
remain in safety or survival follow-up beyond the cut-off point for the primary analyses, 
as allowed by the protocol, will be summarized in a final CSR that will be prepared at the 
end of the study. In the final CSR, analyses will be done for each cohort. For exploratory 
purposes, for patients enrolled in Cohort 1 who do not have FGFR2 fusions or 
translocations, data may be combined and summarized with Cohort 2. 
 
10.1 
Analysis sets 
 
10.1.1 
Full Analysis Set 
 
The Full Analysis Set (FAS) includes all patients who received at least one dose of 
BGJ398. The FAS will be used for all listings of raw data. Unless otherwise specified, the 
FAS will be the default analysis set used for all analyses. 
 
10.1.2 
Interim Efficacy Analysis Set 1 for Cohort 1 
 
The Interim Efficacy Analysis Set 1 for Cohort 1 includes all patients with planned 
extensive PK sample collection (regardless of whether extensive PK samples were 
actually collected) and all patients enrolled prior to amendment 2. Unless otherwise 
specified, the Interim Efficacy Analysis Set 1 will be used as the primary efficacy 
analysis set for the first formal interim analysis for Cohort 1 after amendment 3. Patients 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
99 
 
will be classified according to their baseline genetic status (FGFR2 gene fusions or 
translocations only vs other FGFR genetic alterations). 
 
10.1.3 
Interim Analysis Set 2 for Cohort 1 
 
The Interim Analysis Set 2 for Cohort 1 includes patients in Cohort 1 with FGFR2 gene 
fusions or translocations who have received at least one dose of BGJ398. Interim 
Analysis Set 2 for Cohort 1 will be used as the primary analysis set for the second formal 
interim analysis for Cohort 1 after amendment 3. 
 
10.1.4 
Sensitivity Analysis Set for Cohort 1 
 
The Sensitivity Analysis Set for Cohort 1 includes patients with FGFR2 gene fusions or 
translocations who received BGJ398 at the time of the first formal interim analysis and 
patients who have disease progression according to central imaging review or ended 
treatment by the cutoff date for the second formal interim analysis for Cohort 1 after 
amendment 3. The cutoff date for the second formal interim analysis is planned so that all 
the patients with FGFR2 gene fusions or translocations who received BGJ398 at the time 
of the first formal interim analysis have 10 months follow-up after their initial exposure 
to BGJ398. The Sensitivity Analysis Set for Cohort 1 will be used for supportive 
sensitivity analyses for the second formal interim analysis for Cohort 1. 
 
10.1.5 
Interim Analysis Set for Cohort 3 
 
The Interim Analysis Set for Cohort 3 will include the first 10 dosed patients who have 
the potential to complete second scheduled scan. 
 
10.1.6 
Per-Protocol Set 
 
The Per-Protocol Set (PPS) will consist of a subset of patients in the FAS who are 
compliant with requirements of the Clinical Study Protocol (CSP) in the following ways: 
 
• Patient had an adequate tumor assessment at baseline 
• Patient is evaluable for efficacy 
• Patient had no CSR-reportable protocol deviations that may affect efficacy 
evaluation. 
 
Patients will be evaluable for efficacy if they have at least one response assessed 
differently from ‘unknown’ or ‘not assessed’ as per RECIST v1.1. All CSR-reportable 
protocol deviations leading to exclusion from the PPS will be provided in a listing. 
 
10.1.7 
Pharmacokinetic analysis set 
 
The Pharmacokinetic analysis set (PAS) includes all patients who (a) receive the planned 
treatment, (b) provide at least one evaluable PK concentration, and (c) do not vomit 
within 4 hours after the dosing of BGJ398. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020)

Protocol No. CBGJ398X2204 
 
100 
 
Detailed definition of PAS will be described in the statistical analysis plan (SAP). 
Patients will be removed from the estimation of certain PK parameters on an individual 
basis depending on the number of available blood samples and whether the PK 
parameters can be reliably estimated based on the available blood samples. These 
patients will be identified at the time of the analyses. 
 
10.2 
Patient demographics/other baseline characteristics 
 
Demographic and other baseline data will be listed by patient and summarized 
descriptively. 
 
10.3 
Treatments (study treatment, concomitant therapies, compliance) 
 
10.3.1 
Study treatment 
 
The actual dose and duration in days of BGJ398 treatment and the relative dose intensity 
(computed as the ratio of actual cumulative dose and planned cumulative dose), will be 
listed and summarized by means of descriptive statistics. 
 
10.3.2 
Concomitant therapies 
 
Concomitant medications and significant non-drug therapies prior to and after the start of 
the study drug treatment will be listed by patient and summarized by ATC (anatomical 
therapeutic chemical classification system) term by means of contingency tables. 
 
10.3.3 
Compliance 
 
Compliance to the protocol will be assessed by the number and proportion of patients 
with CSR-reportable protocol deviations. These will be identified prior to database lock 
and will be listed and summarized. Compliance to the study drug will be assessed by the 
number of dose reductions and dose interruptions, see Section 10.5.2.6. 
 
10.4 
Primary objective 
 
10.4.1 
Variable 
 
For Cohort 1, the primary objective of the study is to assess the efficacy of BGJ398 using 
overall response assessed by central imaging review. 
 
Overall response rate (ORR) is defined as the proportion of patients with a best overall 
response of Complete Response (CR) or Partial Response (PR), as per RECIST 
version 1.1 (Appendix 3). 
 
10.4.2 
Statistical hypothesis, model, and method of analysis 
 
It is assumed that the number of responses follow a binomial distribution.

The estimated ORR per central imaging review along with the 95% binomial exact CI 
will be provided. 
 
10.4.3 
Handling of missing values/censoring/discontinuations 
 
Disposition including the reason for discontinuation from study treatment will be 
summarized and listed, along with dates of first and last study treatment, duration of 
exposure to BGJ398 and date of discontinuation for each patient. 
 
Missing data will simply be noted as missing on appropriate listings. 
 
The handling of censoring for time to event endpoints and completely/partial missing 
dates will be described in SAP. 
 
10.5 
Secondary objectives 
 
This section describes analyses of secondary objectives for Cohort 1. The same variables 
will be analyzed for Cohorts 2 and 3 as exploratory, so this section also applies to 
analyses of those variables/endpoints (Section 3). 
 
10.5.1 
Secondary efficacy objectives and variables 
Overall survival 
Overall Survival (OS) is defined as the time from the date of start of treatment to the date 
of death due to any cause. The survival time for patients without documentation of death 
prior to the data cutoff, will be censored at the last date the patient was known to be alive 
prior to the cutoff date. Survival time for patients with no post-baseline survival 
information will be censored at the date of start of treatment. 
 
OS will be analyzed using the Kaplan-Meier (K-M) method. Survival rate at 4, 6, 8, 12, 
18 and 24 months and median OS will be estimated along with 95% confidence intervals 
using the K-M method. 
 
Progression Free Survival 
 
Progression free survival (PFS) is defined as the date of the start of treatment to the date 
of the event defined as the first documented progression or death due to any cause. If 
patient has not had an event, progression- free-survival will be censored according to 
details described in the SAP. K-M analysis of PFS will be provided. 
 
For Cohorts 2 and 3, the percentage of patients who are progression-free at the second 
scheduled scan (approximately 16 weeks from treatment initiation) or later will be 
analyzed using 95% exact binomial confidence interval. Patients who do not have scans 
to show that they are progression-free at the second scheduled scan or later will be 
considered as not benefiting from the study treatment. Sensitivity analysis will be done 
by estimating PFS >16 weeks using K-M estimate.

102 
 
Overall Response Rate (ORR) 
 
ORR (based on overall response assessed by the investigator) will be estimated with 95% 
binomial exact confidence interval. 
 
Best Overall Response and Disease Control Rate 
 
Overall lesion assessments will be listed by patient. Best overall response (BOR) will be 
summarized by the proportion of patients having a best overall response of PR, CR, SD, 
or PD. Disease control rate will be summarized presenting the combined proportion of 
patients having a BOR of CR, PR, or SD. The estimates will be presented along with 
corresponding 95% binomial exact confidence intervals. These analyses will be 
conducted for the central imaging assessment and for the investigator assessment as 
specified by cohort (Section 3). 
 
10.5.2 
Safety objectives and variables 
 
10.5.2.1 
Analysis set and grouping for the analyses 
 
For all safety analyses, the safety analysis set will be used. 
 
The overall observation period will be divided into three mutually exclusive segments: 
 
1. Pre-treatment period: from day of patient’s informed consent to the day before first 
dose of study medication 
 
2. On-treatment period: from day of first dose of study medication to 90 days after last 
dose of study medication 
 
3. Post-treatment period: starting at day 31 after last dose of study medication. 
 
If dates are incomplete in a way that clear assignment to pre-, on-, post-treatment period 
cannot be made, then the respective data will be assigned to the on-treatment period. 
 
10.5.2.2 
Adverse events (AEs) 
 
Summary tables for adverse events (AEs) have to include only AEs that started or 
worsened during the on-treatment period, the treatment-emergent AEs. However, all 
safety data (including those from the pre and post-treatment periods) will be listed and 
treatment-emergent are to be flagged. 
 
The incidence of treatment-emergent adverse events (new or worsening from baseline) 
will be summarized by system organ class and or preferred term, severity (based on 
CTCAE grades), type of adverse event, relationship to study treatment. 
 
Deaths reportable as SAEs and non-fatal serious adverse events will be listed by patient 
and tabulated.

Protocol No. CBGJ398X2204 
 
103 
 
Adverse events of special interest (AESI) will be considered. Each AESI consists of one 
or more well-defined safety events which are similar in nature and for which there is a 
specific clinical interest in connection with the study treatment(s). 
 
For each specified AESI, number and percentage of patients with at least one event 
within the AESI will be reported. 
 
10.5.2.3 
Laboratory abnormalities 
 
For laboratory tests covered by the Common Terminology Criteria for Adverse Events 
(CTCAE) version CTCAE v4.03, Grade 1 or higher will be assigned per CTCAE v4.03. 
Grade 0 will be assigned for all non-missing values not graded as 1 or higher. Grade 5 
will not be used. 
 
For laboratory tests where grades are not defined by CTCAE, results will be categorized 
as low/normal/high based on laboratory normal ranges. 
 
The following by-treatment summaries will be generated separately for hematology, 
biochemistry and urinary laboratory tests: 
 
• Shift tables using CTCAE grades to compare baseline to the worst on-treatment value 
• For laboratory tests where CTCAE grades are not defined, shift tables using the 
low/normal/high/(low and high) classification to compare baseline to the worst 
on-treatment value. 
 
In addition to the tables and listings mentioned above, other exploratory analyses, for 
example figures plotting time course of raw or change in laboratory tests over time or box 
plots might be specified in the SAP. 
 
10.5.2.4 
Other safety data 
 
Data from other tests (eg, electrocardiogram, LVEF, or ophthalmic assessments) will be 
listed, notable values will be flagged. Any statistical tests performed to explore the data 
will be used only to highlight any interesting comparisons that may warrant further 
consideration. Additionally, the following outputs will be produced: 
 
ECG 
 
• Shift table baseline to worst on-treatment result for overall assessments 
• Listing of ECG evaluations for all patients with at least one abnormality. 
Vital signs 
 
• Table with frequency/percentage of patients with abnormal vital signs.

and change from baseline to this/these post-baseline time points. 
 
10.5.2.5 
Supportive analyses for secondary objectives 
 
Not applicable. 
 
10.5.2.6 
Tolerability 
 
Tolerability of study drug will be assessed by summarizing the number of dose 
interruptions and dose reductions. Reasons for dose interruption and dose reductions will 
be listed by patient and summarized. Cumulative dose, dose intensity and relative dose 
intensity of BGJ398 will be summarized. Categories for relative dose intensity of 
BGJ398 will be specified as ≤0.5, >0.5 - ≤0.75, >0.75 - ≤0.9, >0.9 - ≤1.0 and >1.0. The 
number and proportion of patients within each category will be presented. 
 
10.5.3 
Pharmacokinetics 
 
Patients treated with FMI I and some patients treated with FMI III (sparse PK group) will 
have limited PK collected as indicated in Table 10. For these patients, only trough and 2- 
hr or 4-hr plasma concentration data will be available. No PK parameters can be 
calculated for these patients. 
 
A secondary objective of this study is to characterize the single and multiple doses PK of 
BGJ398 FMI III and FMI IV formulations. Data as per Table 11 will be available for 
about 20 patients treated with FMI III and for all patients enrolled in either Cohort 2 or 
Cohort 3 and treated with FMI IV. For these patients, PK parameters as listed in 
Table 13, may be determined from PK profiles after the first dose on Day 1 of Cycle 1 
and Day 15 of Cycle 1 after repeated daily dosing using non-compartmental method(s) of 
WinNonlin (Pharsight, Mountain View, CA).

Data handling principles 
 
All concentrations below the lower limit of quantification (LLOQ) or missing data will 
be labeled as such in the concentration data listings. Concentrations below the LLOQ will 
be treated as zero in summary statistics. 
 
10.5.3.2 
Data analysis principles 
 
Exploratory PK analysis may be conducted based on preliminary data prior to data base 
lock, and nominal time and dose information may be used. 
 
PK data generated from this study may be used in conjunction with PK data from other 
clinical studies for population PK and PK/PD assessment. These assessments will be 
reported separately. If possible, exploratory comparisons will be made to historical 
pharmacokinetic data. Available PK data from this study may be modeled using a 
population pharmacokinetic data analysis approach in order to characterize the population 
pharmacokinetics of BGJ398. Any population PK data generated will be reported 
separate from the CSR. If feasible, exploratory PK and PK/PD analysis may be 
performed, using appropriate methods, to elucidate concentration-response (efficacy 
and/or biomarkers) and/or concentration-toxicity relationships. These analyses will be 
defined in a stand-alone analysis plan document(s), as appropriate, prior to clinical 
database lock. 
 
Descriptive graphical plots of individual and mean plasma concentration (per treatment) 
along with its time course will be generated. Further graphical exploratory analysis will 
be carried out if deemed appropriate.

Analysis will be done separately for the 3 formulations. In addition, analyses that require 
derived PK parameters will be applicable to patients treated with FMI III and FMI IV 
who are expected to provide extensive PK blood samples as indicated in Table 11. 
 
10.5.3.2.1 
Analysis sets 
 
Only PK blood samples with the date and time and for which the last prior dose dates and 
times are adequately recorded will be included in the PK analyses. Samples taken from 
patients who vomited within 4 hours of dosing will be excluded from the analysis. The 
PAS will be used. 
 
10.5.3.2.2 
Basic tables, Figures and Listings 
 
The PK concentration and PK (when available for patients treated with FMI III or FMI 
IV), will be summarized and listed using relevant statistics by formulation, and study day. 
Descriptive statistics (mean, SD, CV% or median [range]) will be presented. When a 
geometric mean is presented, it will be stated as such. Only median values and ranges 
will be presented for Tmax. 
 
Graphical plots of individual and mean plasma concentration-time data will be generated 
for BGJ398 and its metabolites. This graphical presentation will be applicable to patients 
who are treated with FMI III or FMI IV and have PK profile collected as per Table 11. 
 
Median, minimum and maximum will be calculated based on collected samples. All 
analyses will refer to BGJ398 and its metabolites. BGJ398 and its metabolites 
concentration vs time data will be reported. Exploratory PK analysis may be conducted 
based on preliminary data prior to data base lock and nominal time and dose information 
may be used.

10.6.1 
Biomarkers 
 
DNA sequencing will be performed in order to detect changes from baseline in molecular 
and proteomic profiles in tumor tissue from patients who have progressed through 
treatment with BGJ398 using available paired biopsies. 
 
Genetic alterations data will be available from the analysis of cell free tumor DNA and 
will be summarized and will be used for concordance analysis of baseline data and 
correlation analysis with markers with response and/or resistance. 
 
10.6.1.1 
Outline of the data analysis 
 
PD markers collected in the clinical database will be analyzed by QED Therapeutics or 
designated CRO. Since this clinical trial was not designed to address specific hypotheses 
related to patient pre-selection or PD markers, the analysis of this data should be viewed 
as exploratory and hypotheses generating. Analytical results from such analyses may be 
used to generate additional hypotheses that must then be verified with data derived from 
subsequent clinical trials. No adjustment for multiple comparisons is planned. 
 
If the number of samples is inadequate to perform a rigorous data analysis, then the 
available data will only be listed. Additional analyses that may be performed after the 
completion of the end-of-study clinical study report will be documented in separate 
reports. These analyses may include but are not limited to the meta-analysis of data from 
this study combined with data from other studies or the analysis of patient pre-selection 
or PD markers generated from samples collected during the study but analyzed after the 
database lock and completion of the clinical study report. 
 
10.6.1.2 
Data handling principles 
 
All measurements below their respective LLOQs or missing data will be labeled as such 
in the concentration data listings. Measurements below the LLOQ will be treated as zero

Correlation of baseline amplification status of FGFR or mutation status and clinical 
antitumor activity outcome will be summarized and may be explored graphically. 
 
Individual CA19-9 serum levels (or change from baseline) will be listed as well as 
presented as line plots over time. If enough data is available, statistical analysis will be 
performed in order to assess the relationship between anti-tumor activity (BOR and OS) 
and CA19-9 levels (or change from baseline). 
 
Patient’s FGFR2 gene fusion status in DNA from non-tumor tissue (cell free DNA data) 
will be listed and compared to the FGFR2 gene fusion status in tumor tissue at baseline; a 
contingency table will be presented. Genetic alterations detected in cell free tumor DNA 
will be summarized and presented graphically for patients with both baseline and post- 
baseline samples. If there is enough data, change from baseline expression levels will be 
correlated with efficacy data. Further exploratory analyses will be performed if feasible. 
 
10.6.1.3.3 
Advanced analysis methods 
 
Any advance analyses e.g. to assess potential correlation between baseline molecular 
status and clinical response, will be defined in a stand-alone analysis plan document, as 
appropriate. 
 
10.6.2 
Objectives for Cohorts 2 and 3 
 
The variables for the exploratory objectives for Cohorts 2 and 3 are defined and analyzed 
as described in the previous sections, as applicable. 
 
10.7 
Interim analysis 
 
Safety and efficacy data will be continuously monitored by QED Therapeutics in 
conjunction with the investigators for decision-making purposes. Please refer to 
Section 4.2 on the timing of the interim analysis. 
 
Specifically, two formal interim analyses are planned for Cohort 1 after amendment 3: 
 
• The first formal interim analysis for Cohort 1 was conducted when all patients in the 
Interim Efficacy Analysis Set 1 had been followed for at least 10 months after their 
initial exposure to BGJ398. Primary efficacy analyses were conducted for the Interim 
Efficacy Analysis Set 1, and key efficacy analyses were repeated for the Full Analysis 
Set. Safety analyses were conducted on the Full Analysis Set. 
 
• The second formal interim analysis for Cohort 1 is planned when all patients who 
received BGJ398 at the time of the first formal interim analysis after amendment 3 
have at least 10 months follow-up after their initial exposure to BGJ398. For this 
interim analysis, the primary analyses will be conducted on the Interim Analysis Set 2 
for Cohort 1. The Sensitivity Analysis Set for Cohort 1 will be used for supportive 
sensitivity analyses.

109 
 
For Cohort 3, a formal interim analysis will be conducted when the first dosed 10 patients 
in Cohort 3 have the potential to complete the second scheduled scan. This is to 
determine if an additional 10 patients will be added to Cohort 3. 
 
10.8 
Sample size calculation 
 
10.8.1 
Cohort 1 
 
At the time of the first formal interim analysis after amendment 3, the Interim Efficacy 
Analysis Set 1 will include 72 patients with FGFR2 gene fusions or translocations. The 
half-width of the exact 95% confidence interval for ORR will not exceed 12%. 
 
With at least 106 patients with FGFR2 gene fusions or translocations, the half-width of 
the exact 95% confidence interval width of ORR will not exceed 10%. 
 
10.8.2 
Cohorts 2 and 3 
 
In Cohorts 2 and 3, patients who are progression-free at the second scheduled scan 
(approximately 16 weeks from treatment initiation) or later will be considered to be 
benefiting from study treatment. If the lower bound of the patients who are progression- 
free at the second scheduled scan (approximately 16 weeks) or later excludes 20%, the 
treatment will be considered as benefiting the patients. 
 
For Cohort 2, the percentage of patients who are progression-free at the second scheduled 
scan (approximately 16 weeks) or later will be estimated with 95% exact confidence 
interval. There will be approximately 20 patients in total. A sample size of 20 will result 
in the exact 95% confidence interval half width of less than 23%. Patients who withdraw 
from the study for any reason before the second scheduled scan will be considered as not 
benefiting from study treatment. Sensitivity analysis will be conducted using the K-M 
method to estimate PFS >16 weeks. 
 
Table 14 provides some examples of CIs corresponding to observed numbers of patients 
considered to have benefited from treatment. For example, if 9 of 20 patients are 
progression-free at the second scheduled scan or later, then the lower bound of the 95% 
exact confidence interval (CI) will exclude 20%. 
 
In Cohort 3, the same definition of benefit rate as for Cohort 2 (the percentage of patients 
who are progression-free at the second scheduled scan [approximately 16 weeks] or later) 
will be applied. The benefit rate will be estimated with 95% exact confidence interval. 
The planned enrollment for Cohort 3 is a maximum of 20 patients. With 20 patients, the 
exact 95% confidence interval half width is <23%. One interim analysis is planned when 
10 patients have been dosed and have the potential to be followed up for response for at 
least 2 scheduled scans. If at the interim analysis, ≥4 patients are progression-free at the 
second scheduled scan (after approximately 16 weeks) or later, the cohort will continue to 
enroll the additional 10 patients; otherwise, enrollment will stop at 10 patients. If ≤20% 
patients are benefiting from the study treatment, there is <12.1% chance that the decision 
after the interim analysis will lead to continuing enrollment.

The percentage of patients considered to have benefited from treatment will be estimated 
with 95% exact binomial CI. If all 20 patients are enrolled, the exact 95% CI half width 
will not exceed 23%. Table 14 provides some examples of CIs corresponding to observed 
numbers of patients considered to have benefited from treatment. At the final analysis, if 
9 of 20 patients who are progression-free at the second scheduled scan or later, the lower 
bound of the 95% exact CI will exclude 20%.

may be requested to present poster or oral presentation at scientific congress; however, 
there will be no honorarium provided for such presentations. 
 
As part of its commitment to full transparency in publications, QED Therapeutics 
supports the full disclosure of all funding sources for the study and publications, as well 
as any actual and potential conflicts of interest of financial and non-financial nature by all 
authors, including medical writing/editorial support, if applicable. 
 
11.6 
Study documentation, record keeping and retention of documents 
 
Each participating site will maintain appropriate medical and research records for this 
trial, in compliance with Section 4.9 of the ICH E6 GCP, and regulatory and institutional 
requirements for the protection of confidentiality of subjects. As part of participating in a 
QED Therapeutics-sponsored study, each site will permit authorized representatives of 
the sponsor(s) and regulatory agencies to examine (and when required by applicable law, 
to copy) clinical records for the purposes of quality assurance reviews, audits and 
evaluation of the study safety and progress. 
 
Source data are all information, original records of clinical findings, observations, or 
other activities in a clinical trial necessary for the reconstruction and evaluation of the 
trial. Examples of these original documents and data records include, but are not limited 
to, hospital records, clinical and office charts, laboratory notes, memoranda, subjects’ 
diaries or evaluation checklists, pharmacy dispensing records, recorded data from 
automated 
 
instruments, copies or transcriptions certified after verification as being accurate and 
complete, microfiches, photographic negatives, microfilm or magnetic media, x-rays, and 
subject files and records kept at the pharmacy, at the laboratories, and medico-technical 
departments involved in the clinical trial. 
 
Data collection is the responsibility of the clinical trial staff at the site under the 
supervision of the site Principal Investigator. The study case report form (CRF) is the 
primary data collection instrument for the study. The investigator should ensure the 
accuracy, completeness, legibility, and timeliness of the data reported in the CRFs and all 
other required reports. Data reported on the CRF, that are derived from source 
documents, should be consistent with the source documents or the discrepancies should 
be explained. All data requested on the CRF must be recorded. Any missing data must be 
explained. Any change or correction to a paper CRF should be dated, initialed, and 
explained (if necessary) and should not obscure the original entry. For electronic CRFs an 
audit trail will be maintained by the system. The investigator should retain records of the 
changes and corrections to paper CRFs.

The investigator/institution should maintain the trial documents as specified in Essential 
Documents for the Conduct of a Clinical Trial (ICH E6 Section 8) and as required by 
applicable regulations and/or guidelines. The investigator/institution should take 
measures to prevent accidental or premature destruction of these documents. 
Essential documents (written and electronic) should be retained for a period of not less 
than fifteen (15) years from the completion of the Clinical Trial unless Sponsor provides 
written permission to dispose of them or, requires their retention for an additional period 
of time because of applicable laws, regulations and/or guidelines 
 
11.7 
Confidentiality of study documents and patient records 
 
The investigator must ensure pseudonymization of the patients by replacing names with 
the study-specific subject identification number; patients must not be identified by names 
in any documents submitted to QED Therapeutics. Signed informed consent forms and 
patient enrollment log must be kept strictly confidential to enable patient identification at 
the site. The names of study patients and all other confidential information are subject to 
medical confidentiality and the provisions of the General Data Protection Regulation 
(GDPR) and other applicable regulations or laws. Patient data may only be passed on in 
pseudonymized form beyond the study center. Third parties do not have access to original 
documents. 
 
11.8 
Audits and inspections 
 
Source data/documents must be available for inspection by QED Therapeutics or 
designee or Health Authorities. 
 
11.9 
Financial disclosures 
 
Financial disclosures should be provided by study personnel who are directly involved in 
the treatment or evaluation of patients at the site - prior to study start. 
 
12 PROTOCOL ADHERENCE 
Investigators ascertain they will apply due diligence to avoid protocol deviations. Under 
no circumstances should the investigator contact QED Therapeutics or its agents, if any, 
monitoring the study to request approval of a protocol deviation, as no authorized 
deviations are permitted. If the investigator feels a protocol deviation would improve the 
conduct of the study this must be considered a protocol amendment, and unless such an 
amendment is agreed upon by QED Therapeutics and approved by the IRB/IEC/REB it 
cannot be implemented. All significant protocol deviations will be recorded and reported 
in the CSR. 
 
12.1 
Amendments to the protocol 
 
Any change or addition to the protocol can only be made in a written protocol 
amendment that must be approved by QED Therapeutics, Health Authorities where 
required, and the IRB/IEC/REB.

Only amendments that are required for patient safety may be implemented prior to 
IRB/IEC/REB approval. Notwithstanding the need for approval of formal protocol 
amendments, the investigator is expected to take any immediate action required for the 
safety of any patient included in this study, even if this action represents a deviation from 
the protocol. In such cases, QED Therapeutics should be notified of this action and the 
IRB/IEC at the site should be informed according to local regulations (e.g. UK requires 
the notification of urgent safety measures within 3 days) but not later than 10 working 
days.

14.3 
Appendix 3: Guidelines for assessments of response 
 
14.3.1 
Introduction 
 
The purpose of this document is to provide the working definitions and rules necessary 
for a consistent and efficient analysis of efficacy for oncology studies in solid tumors. 
This document is based on the RECIST criteria for tumor responses (Therasse 2000) and 
the revised RECIST 1.1 guidelines (Eisenhauer 2009). 
 
14.3.2 
Disease measurability 
 
In order to evaluate tumors throughout a study, definitions of measurability are required 
in order to classify lesions appropriately at baseline. In defining measurability, a 
distinction also needs to be made between nodal lesions (pathological lymph nodes) and 
non-nodal lesions. 
 
• Measurable disease - the presence of at least one measurable nodal or non-nodal 
lesion. If the measurable disease is restricted to a solitary lesion, its neoplastic nature 
should be confirmed by cytology/histology. 
 
Measurable lesions (both nodal and non-nodal) 
 
• Measurable non-nodal - As a rule of thumb, the minimum size of a measurable non- 
nodal target lesion at baseline should be no less than double the slice thickness or 
10mm whichever is greater - e.g. the minimum non-nodal lesion size for CT/MRI 
with 5mm cuts will be 10 mm, for 8 mm contiguous cuts the minimum size will be 16 
mm. 
 
• Lytic bone lesions or mixed lytic-blastic lesions with identifiable soft tissue 
components that can be evaluated by CT/MRI, can be considered as measurable 
lesions, if the soft tissue component meets the definition of measurability. 
 
• Measurable nodal lesions (i.e. lymph nodes) - Lymph nodes ≥15 mm in short axis 
can be considered for selection as target lesions. Lymph nodes measuring ≥10 mm 
and <15 mm are considered non-measurable. Lymph nodes smaller than 10 mm in 
short axis at baseline, regardless of the slice thickness, are normal and not considered 
indicative of disease. 
 
Cystic lesions: 
 
• Lesions that meet the criteria for radiographically defined simple cysts (ie, spherical 
structure with a thin, non-irregular, non-nodular and non-enhancing wall, no 
septations, and low CT density [water-like] content) should not be considered as 
malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts. 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
121 
 
• ‘Cystic lesions’ thought to represent cystic metastases can be considered as 
measurable lesions, if they meet the definition of measurability described above. 
However, if noncystic lesions are present in the same patient, these are preferred for 
selection as target lesions. 
 
• Non-measurable lesions - all other lesions are considered non-measurable, including 
small lesions (e.g. longest diameter <10 mm with CT/MRI or pathological lymph 
nodes with ≥ 10 to < 15 mm short axis), as well as truly non-measurable lesions eg, 
blastic bone lesions, leptomeningeal disease, ascites, pleural/pericardial effusion, 
inflammatory breast disease, lymphangitis cutis/pulmonis, abdominal 
masses/abdominal organomegaly identified by physical exam that is not measurable 
by reproducible imaging techniques. 
 
14.3.3 
Methods of tumor measurement - general guidelines 
In this document, the term “contrast” refers to intravenous (i.v.) contrast. 
The following considerations are to be made when evaluating the tumor: 
• All measurements should be taken and recorded in metric notation (mm), using a 
ruler or calipers. All baseline evaluations should be performed as closely as possible 
to the beginning of treatment and never more than 4 weeks before the beginning of 
the treatment. 
 
• Imaging-based evaluation is preferred to evaluation by clinical examination when 
both methods have been used to assess the antitumor effect of a treatment. 
 
• For optimal evaluation of patients, the same methods of assessment and technique 
should be used to characterize each identified and reported lesion at baseline and 
during followup. Contrast-enhanced CT of chest, abdomen and pelvis should 
preferably be performed using a 5 mm slice thickness with a contiguous 
reconstruction algorithm. CT/MRI scan slice thickness should not exceed 8 mm cuts 
using a contiguous reconstruction algorithm. If, at baseline, a patient is known to have 
a medical contraindication to CT contrast or develops a contraindication during the 
trial, the following change in imaging modality will be accepted for follow-up: a non- 
contrast CT of chest (MRI not recommended due to respiratory artifacts) plus 
contrast-enhanced MRI of abdomen and pelvis. 
 
• A change in methodology can be defined as either a change in contrast use (e.g. 
keeping the same technique, like CT, but switching from with to without contrast use 
or vice-versa, regardless of the justification for the change) or a change in technique 
(e.g. from CT to MRI, or vice-versa), or a change in any other imaging modality. A 
change in methodology will result by default in a UNK overall lesion response 
assessment. However, another response assessment than the QED Therapeutics 
calculated UNK response may be accepted from the investigator or the central 
blinded reviewer if a definitive response assessment can be justified, based on the 
available information.

• FDG-PET: can complement CT scans in assessing progression (particularly possible 
for ‘new’ disease). New lesions on the basis of FDG-PET imaging can be identified 
according to the following algorithm: 
 
○ Negative FDG-PET at baseline, with a positive FDG-PET at follow-up is a sign of 
PD based on a new lesion. 
 
○ No FDG-PET at baseline with a positive FDG-PET at follow-up: 
 
• If the positive FDG-PET at follow-up corresponds to a new site of disease confirmed 
by CT, this is PD. 
 
• If the positive FDG-PET at follow-up is not confirmed as a new site of disease on CT, 
additional follow-up CT are needed to determine if there is truly progression 
occurring at that Site (if so, the date of PD will be the date of the initial abnormal CT 
scan). 
 
• If the positive FDG-PET at follow-up corresponds to a pre-existing site of disease on 
CT that is not progressing on the basis of the anatomic images, this is not PD. 
 
• Chest x-ray: Lesions on chest x-ray are acceptable as measurable lesions when they 
are clearly defined and surrounded by aerated lung. However, CT is preferable. 
 
• Ultrasound: When the primary endpoint of the study is overall response evaluation, 
ultrasound (US) should not be used to measure tumor lesions. It is, however, a 
possible alternative to clinical measurements of superficial palpable lymph nodes, 
subcutaneous lesions and thyroid nodules. US might also be useful to confirm the 
complete disappearance of superficial lesions usually assessed by clinical 
examination. 
 
• Endoscopy and laparoscopy: The utilization of endoscopy and laparoscopy for 
objective tumor evaluation has not yet been fully and widely validated. Their uses in 
this specific context require sophisticated equipment and a high level of expertise that 
may only be available in some centers. Therefore, the utilization of such techniques 
for objective tumor response should be restricted to validation purposes in specialized 
centers. However, such techniques can be useful in confirming complete pathological 
response when biopsies are obtained. 
 
• Tumor markers: Tumor markers alone cannot be used to assess response. However, 
some disease specific and more validated tumor markers (e.g. CA-125 for ovarian 
cancer, PSA for prostate cancer, alpha-FP, LDH and Beta-hCG for testicular cancer) 
can be integrated as non-target disease. If markers are initially above the upper 
normal limit they must normalize for a patient to be considered in complete clinical 
response when all lesions have disappeared. 
 
• Cytology and histology: Cytology and histology can be used to differentiate between 
PR and CR in rare cases (ie, after treatment to differentiate between residual benign

123 
 
lesions and residual malignant lesions in tumor types such as germ cell tumors). 
Cytologic confirmation of neoplastic nature of any effusion that appears or worsens 
during treatment is required when the measurable tumor has met the criteria for 
response or stable disease. Under such circumstances, the cytologic examination of 
the fluid collected will permit differentiation between response and stable disease (an 
effusion may be a side effect of the treatment) or progressive disease (if the neoplastic 
origin of the fluid is confirmed). 
 
• Clinical examination: Clinical lesions will only be considered measurable when they 
are superficial (ie, skin nodules and palpable lymph nodes). For the case of skin 
lesions, documentation by color photography, including a ruler to estimate the size of 
the lesion, is recommended. 
 
14.3.4 
Baseline documentation of target and non-target lesions 
 
For the evaluation of lesions at baseline and throughout the study, the lesions are 
classified at baseline as either target or non-target lesions: 
 
• Target lesions: All measurable lesions (nodal and non-nodal) up to a maximum of 
five lesions in total (and a maximum of two lesions per organ), representative of all 
involved organs should be identified as target lesions and recorded and measured at 
baseline. Target lesions should be selected on the basis of their size (lesions with the 
longest diameter) and their suitability for accurate repeated measurements (either by 
imaging techniques or clinically). Each target lesion must be uniquely and 
sequentially numbered on the CRF (even if it resides in the same organ). 
 
Minimum target lesion size at baseline 
 
• Non-nodal target: Non-nodal target lesions identified by methods for which slice 
thickness is not applicable (e.g. clinical examination, photography) should be at least 
10 mm in longest diameter. See Section 14.3.2. 
 
• Nodal target: See Section 14.3.9. 
A sum of diameters (long axis for non-nodal lesions, short axis for nodal) for all target 
lesions will be calculated and reported as the baseline sum of diameters (SOD). The 
baseline sum of diameters will be used as reference by which to characterize the objective 
tumor response. Each target lesion identified at baseline must be followed at each 
subsequent evaluation and documented on eCRF. 
 
• Non-target lesions: All other lesions are considered non-target lesions, i.e. lesions 
not fulfilling the criteria for target lesions at baseline. Presence or absence or 
worsening of non-target lesions should be assessed throughout the study; 
measurements of these lesions are not required. Multiple non-target lesions involved 
in the same organ can be assessed as a group and recorded as a single item (i.e. 
multiple liver metastases). Each non-target lesion identified at baseline must be 
followed at each subsequent evaluation and documented on eCRF.

14.3.5 
Follow-up evaluation of target and non-target lesions 
 
To assess tumor response, the sum of diameters for all target lesions will be calculated (at 
baseline and throughout the study). At each assessment response is evaluated first 
separately for the target (Table 17) and non-target lesions (Table 18) identified at 
baseline. These evaluations are then used to calculate the overall lesion response 
considering both the target and non-target lesions together (Table 19) as well as the 
presence or absence of new lesions. 
 
14.3.6 
Follow-up and recording of lesions 
 
At each visit and for each lesion the actual date of the scan or procedure which was used 
for the evaluation of each specific lesion should be recorded. This applies to target and 
non-target lesions as well as new lesions that are detected. At the assessment visit all of 
the separate lesion evaluation data are examined by the investigator in order to derive the 
overall visit response. Therefore, all such data applicable to a particular visit should be 
associated with the same assessment number. 
 
14.3.7 
Non-nodal lesions 
 
Following treatment, lesions may have longest diameter measurements smaller than the 
image reconstruction interval. Lesions smaller than twice the reconstruction interval are 
subject to substantial “partial volume” effects (ie, size may be underestimated because of 
the distance of the cut from the longest diameter; such lesions may appear to have 
responded or progressed on subsequent examinations, when, in fact, they remain the 
same size). 
 
If the lesion has completely disappeared, the lesion size should be reported as 0 mm. 
 
Measurements of non-nodal target lesions that become 5 mm or less in longest diameter 
are likely to be non-reproducible. Therefore, it is recommended to report a default value 
of 5 mm, instead of the actual measurement. This default value is derived from the 5 mm 
CT slice thickness (but should not be changed with varying CT slice thickness). Actual 
measurement should be given for all lesions larger than 5 mm in longest diameter 
irrespective of slice thickness/reconstruction interval. 
 
In other cases where the lesion cannot be reliably measured for reasons other than its size 
(eg, borders of the lesion are confounded by neighboring anatomical structures), no 
measurement should be entered and the lesion cannot be evaluated. 
 
14.3.8 
Nodal lesions 
 
A nodal lesion less than 10 mm in size by short axis is considered normal. Lymph nodes 
are not expected to disappear completely, so a “non-zero size” will always persist. 
 
Measurements of nodal target lesions that become 5 mm or less in short axis are likely to 
be non-reproducible. Therefore, it is recommended to report a default value of 5 mm, 
instead of the actual measurement. This default value is derived from the 5 mm CT slice

thickness (but should not be changed with varying CT slice thickness). Actual 
measurement should be given for all lesions larger than 5 mm in short axis irrespective of 
slice thickness/reconstruction interval. 
 
However, once a target nodal lesion shrinks to less than 10 mm in its short axis, it will be 
considered normal for response purpose determination. The lymph node measurements 
will continue to be recorded to allow the values to be included in the sum of diameters for 
target lesions, which may be required subsequently for response determination. 
 
14.3.9 
Determination of target lesion response 
Table 17:  Response criteria for target lesions 
Response Criteria 
Evaluation of target lesions 
Complete Response (CR): 
Disappearance of all non-nodal target lesions. In addition, any pathological 
lymph nodes assigned as target lesions must have a reduction in short axis to < 
10 mm 1 
 
Partial Response (PR): 
At least a 30% decrease in the sum of diameter of all target lesions, taking as 
reference the baseline sum of diameters. 
 
Progressive Disease (PD): 
At least a 20% increase in the sum of diameter of all measured target lesions, 
taking as reference the smallest sum of diameter of all target lesions recorded at 
or after baseline. In addition to the relative increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5 mm.2 
 
Stable Disease (SD): 
Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions 
which would qualify for PD. 
 
Unknown (UNK) 
Progression has not been documented and one or more target lesions have not 
been assessed or have been assessed using a different method than baseline.3

SOD for CR may not be zero when nodal lesions are part of target lesions

Following an initial CR, a PD cannot be assigned if all non-nodal target lesions are still not present and 
all nodal lesions are <10 mm in size. In this case, the target lesion response is CR

Notes on target lesion response 
 
Reappearance of lesions: If the lesion appears at the same anatomical location where a 
target lesion had previously disappeared, it is advised that the time point of lesion 
disappearance (ie, the “0 mm” recording) be re-evaluated to make sure that the lesion was 
not actually present and/or not visualized for technical reasons in this previous 
assessment. If it is not possible to change the 0 value, then the investigator/radiologist has 
to decide between the following three possibilities: 
 
• The lesion is a new lesion, in which case the overall tumor assessment will be 
considered as progressive disease 

QED Therapeutics 
Amended Protocol Version 06 (15-Jan-2020) 
Confidential 
 
Protocol No. CBGJ398X2204 
 
126 
 
• The lesion is clearly a reappearance of a previously disappeared lesion, in which case 
the size of the lesion has to be entered in the CRF and the tumor assessment will 
remain based on the sum of tumor measurements as presented in Table 17 above (ie, a 
PD will be determined if there is at least 20% increase in the sum of diameters of all 
measured target lesions, taking as reference the smallest sum of diameters of all target 
lesions recorded at or after baseline with at least 5 mm increase in the absolute sum of 
the diameters). Proper documentation should be available to support this decision. 
This applies to patients who have not achieved target response of CR. For patients 
who have achieved CR, please refer to last bullet in this section. 
 
• For those patients who have only one target lesion at baseline, the reappearance of the 
target lesion which disappeared previously, even if still small, is considered a PD. 
 
• Missing measurements: In cases where measurements are missing for one or more 
target lesions it is sometimes still possible to assign PD based on the measurements of 
the remaining lesions. For example, if the sum of diameters for 5 target lesions at 
baseline is 100 mm at baseline and the sum of diameters for 3 of those lesions at a 
post-baseline visit is 140 mm (with data for 2 other lesions missing) then a PD should 
be assigned. However, in other cases where a PD cannot definitely be attributed, the 
target lesion response would be UNK. 
 
• Nodal lesion decrease to normal size: When nodal disease is included in the sum of 
target lesions and the nodes decrease to “normal” size they should still have a 
measurement recorded on scans. This measurement should be reported even when the 
nodes are normal in order not to overstate progression should it be based on increase 
in the size of nodes. 
 
• Lesions split: In some circumstances, disease that is measurable as a target lesion at 
baseline and appears to be one mass can split to become two or more smaller sub- 
lesions. When this occurs, the diameters (long axis - non-nodal lesion, short axis - 
nodal lesions) of the two split lesions should be added together and the sum recorded 
in the diameter field on the case report form under the original lesion number. This 
value will be included in the sum of diameters when deriving target lesion response. 
The individual split lesions will not be considered as new lesions, and will not 
automatically trigger a PD designation. 
 
• Lesions coalesced: Conversely, it is also possible that two or more lesions which 
were distinctly separate at baseline become confluent at subsequent visits. When this 
occurs a plane between the original lesions may be maintained that would aid in 
obtaining diameter measurements of each individual lesion. If the lesions have truly 
coalesced such that they are no longer separable, the maximal diameters (long axis - 
non-nodal lesion, short axis nodal lesions) of the “merged lesion” should be used 
when calculating the sum of diameters for target lesions. On the case report form, the 
diameter of the “merged lesion” should be recorded for the size of one of the original 
lesions while a size of “0”mm should be entered for the remaining lesion numbers 
which have coalesced.

• The measurements for nodal lesions, even if less than 10 mm in size, will contribute 
to the calculation of target lesion response in the usual way with slight modifications. 
 
○ Since lesions less than 10 mm are considered normal, a CR for target lesion 
response should be assigned when all nodal target lesions shrink to less than 10 
mm and all non-nodal target lesions have disappeared. 
 
○ Once a CR target lesion response has been assigned a CR will continue to be 
appropriate (in the absence of missing data) until progression of target lesions. 
 
○ Following a CR, a PD can subsequently only be assigned for target lesion 
response if either a non-nodal target lesion “reappears” or if any single nodal 
lesion is at least 10 mm and there is at least 20% increase in sum of the diameters 
of all nodal target lesions relative to nadir with at least 5 mm increase in the 
absolute sum of the diameters.

Determination of non-target lesion response 
Table 18:  Response criteria for non-target lesions 
Response Criteria 
Evaluation of non-target lesions 
Complete Response (CR): 
Disappearance of all non-target lesions. In addition, all lymph nodes assigned 
a non-target lesions must be non-pathological in size (< 10 mm short axis) 
 
Progressive Disease (PD): 
Unequivocal progression of existing non-target lesions.1 
Non-CR/Non-PD: 
Neither CR nor PD 
Unknown (UNK) 
Progression has not been documented and one or more non-target lesions 
have not been assessed or have been assessed using a different method than 
baseline. 
 
1 
Although a clear progression of non-target lesions only is exceptional, in such circumstances, the 
opinion of the treating physician does prevail and the progression status should be confirmed later on 
by the review panel (or study chair). 
 
Notes on non-target lesion response 
 
• The response for non-target lesions is CR only if all non-target non-nodal lesions 
which were evaluated at baseline are now all absent and with all non-target nodal 
lesions returned to normal size (i.e. < 10 mm). If any of the non-target lesions are still 
present, or there are any abnormal nodal lesions (i.e. ≥ 10 mm) the response can only 
be ‘NonCR/Non-PD’ unless any of the lesions was not assessed (in which case 
response is UNK) or there is unequivocal progression of the non-target lesions (in 
which case response is PD). 
 
• Unequivocal progression: To achieve “unequivocal progression” on the basis of non- 
target disease there must be an overall level of substantial worsening in non-target 
disease such that, even in presence of CR, PR or SD in target disease, the overall 
tumor burden has increased sufficiently to merit discontinuation of therapy. A modest

“increase” in the size of one or more non-target lesions is usually not sufficient to 
qualify for unequivocal progression status. The designation of overall progression 
solely on the basis of change in non-target disease in the face of CR, PR or SD of 
target disease is therefore expected to be rare. In order for a PD to be assigned on the 
basis of non-target lesions, the increase in the extent of the disease must be 
substantial even in cases where there is no measurable disease at baseline. If there is 
unequivocal progression of non-target lesion(s), then at least one of the non-target 
lesions must be assigned a status of “Worsened”. Where possible, similar rules to 
those described in Section 14.3.10 (Determination of target lesion response) for 
assigning PD following a CR for the non-target lesion response in the presence of 
non-target lesions nodal lesions should be applied. 
 
14.3.11 
New lesions 
 
The appearance of a new lesion is always associated with Progressive Disease (PD) and 
has to be recorded as a new lesion in the New Lesion CRF page. 
 
• If a new lesion is equivocal, for example because of its small size, continued therapy 
and follow-up evaluation will clarify if it represents truly new disease. If repeat scans 
confirm there is definitely a new lesion, then progression should be declared using the 
date of the first observation of the lesion. 
 
• If new disease is observed in a region which was not scanned at baseline or where 
the particular baseline scan is not available for some reason, then this should be 
considered as a PD. The one exception to this is when there are no baseline scans at 
all available for a patient in which case the response should be UNK, as for any of 
this patient's assessment (see Section 14.3.13). 
 
• A lymph node is considered as a “new lesion” and, therefore, indicative of 
progressive disease if the short axis increases in size to ≥10 mm for the first time in 
the study plus 5 mm absolute increase. 
FDG-PET: can complement CT scans in assessing progression (particularly possible 
for ‘new’ disease). See Section 14.3.4.

Evaluation of overall lesion response 
 
The evaluation of overall lesion response at each assessment is a composite of the target 
lesion response, non-target lesion response and presence of new lesions as shown below 
in Table 19.

This overall lesion response also applies when there are no non-target lesions identified at baseline.

Unconfirmed PR will be considered SD for analysis purposes. If there are no baseline scans available 
at all, then the overall lesion response at each assessment should be considered Unknown (UNK). 
 
If the evaluation of any of the target lesions identified at baseline could not be made 
during follow-up, the overall status must be ‘unknown’ unless progression was seen. 
 
In some circumstances it may be difficult to distinguish residual disease from normal 
tissue. When the evaluation of complete response depends on this determination, it is 
recommended that the residual lesion be investigated (fine needle aspirate/biopsy) to 
confirm the CR.

Appendix 5: List of Highly Effective Methods of Contraception 
 
The following is from the Clinical Trials Facilitation Group 2014 (Section 4.1). 
 
Methods that can achieve a failure rate of less than 1% per year when used consistently 
and correctly are considered as highly effective birth control methods. Such methods 
include: 
 
• combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation 1: 
○ oral 
 
○ intravaginal 
 
○ transdermal 
 
• progestogen-only hormonal contraception associated with inhibition of ovulation 1: 
○ oral 
 
○ injectable 
 
○ implantable 2 
• intrauterine device (IUD) 2 
• intrauterine hormone-releasing system (IUS) 2 
• bilateral tubal occlusion 2 
• vasectomised partner 2,3 
• sexual abstinence 4 
 
 
1 Hormonal contraception may be susceptible to interaction with the IMP, which may reduce the efficacy 
of the contraception method (see Clinical Trials Facilitation Group 2014, section 4.3). 
2 Contraception methods that in the context of this guidance are considered to have low user dependency. 
3 Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual 
partner of the WOCBP trial participant and that the vasectomised partner has received medical 
assessment of the surgical success. 
4 In the context of this guidance sexual abstinence is considered a highly effective method only if defined 
as refraining from heterosexual intercourse during the entire period of risk associated with the study 
treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the 
clinical trial and the preferred and usual lifestyle of the subject.
