Detailed description:
This is a Phase 2, non-comparative, open-label, multicenter study of AL101 in patients with recurrent or metastatic ACC who harbor NOTCH 1,2,3,4 activating mutations.

The study includes 2 cohorts, ran in a sequential fashion:

Cohort 1 - AL101 4 mg once weekly (QW) intravenously (IV) Cohort 2 - AL101 6 mg QW IV

Arms:
arm 1: AL101 is an inhibitor of gamma secretase-mediated Notch signaling.

Interventions: intervention 1: AL101
Intervention descriptions: intervention 1: AL101 is a small-molecule that inhibits gamma secretase, an enzyme which plays a key role in the activation of the Notch signaling pathway by releasing the Notch intracellular domain (NICD) of all four Notch receptors from the membrane.

In patients with aberrant Notch signaling, AL101 may inhibit Notch signaling and potentially impede tumor growth.The drug is administered intravenously

PROTOCOL SYNOPSIS
Study Title
A Phase 2, Open-Label, multi-center Study of AL101 in patients with adenoid cystic carcinoma 
(ACC) bearing activating Notch mutations
Protocol No. AL-ACC-01
Study Phase
Phase 2
Clinical Sites
Approximately 16 sites in North America, and 10 sites in Europe 
and Israel
Study Rationale
AL101 is a potent and selective inhibitor of gamma secretase-mediated Notch signaling that is 
currently under development as an antitumor/antiangiogenic agent for single use or in 
combination with cytotoxic agents as well as other targeted agents in the treatment of tumor 
growth and metastasis. A large body of experimental evidence supports a causal role of 
activating Notch mutations in tumorigenesis. In adenoid cystic carcinoma (ACC), sequencing 
of tumor samples revealed genomic alterations in the Notch pathway in a subset of patients with 
a distinct ACC phenotype. ACC patients with NOTCH1 mutations have an aggressive disease 
with a distinct pattern of metastasis and worse prognosis than their wild type counterparts. In 
addition to NOTCH1 mutations, other NOTCH mutations (2, 3, 4) were identified in ACC. There 
are currently no available therapies for these patients. Therefore, ACC with Notch pathway 
activation represents a high unmet therapeutic need.
Objectives
Endpoints
Primary

To assess the clinical activity of AL101 
using radiographic assessments and 
Response Evaluation Criteria in Solid 
Tumors (RECIST) v1.1 in ACC 
patients 
with 
activating 
Notch 
mutations

Objective response rate (ORR; complete 
response [CR] and partial response [PR])

Study Design
This is a Phase 2, non-comparative, open-label, multicenter study of AL101 in patients with 
recurrent or metastatic ACC who harbor NOTCH 1,2,3,4 activating mutations.
The study includes 2 cohorts, ran in a sequential fashion:

Cohort 1 – AL101 4 mg once weekly (QW) intravenously (IV)

Cohort 2 – AL101 6 mg QW IV
Cohort 1 will continue to enroll to reach up to a maximum of 45 patients. Cohort 2 will open 
for enrollment up to a maximum of 42 patients.
Prior to entering the study, to determine eligibility, potential candidates will undergo 
pre-screening assessment and confirmation for the presence of activating Notch mutations. 
Available mutation status from prior tests with any commercially available or locally 
developed NGS assay are acceptable. In Europe any commercially available CE marked 
device shall be used (for country specific requirements refer to Appendix E).
If historical genotyping results are not available, testing will need to be conducted during pre-
screening using a laboratory developed or commercially available NGS assay to identify and 
confirm an activating Notch mutation. Any newly characterized mutation (such as tandem 
duplication, variant allele frequency, variants of unknown significance, etc.), will be evaluated 
with the Sponsor on a case-by-case basis. Pre-screening study-specific assessments may be 
done while potential candidates are on other therapy provided that a separate pre-screening 
informed consent form is signed.
Patients with activating Notch mutations will then undergo screening assessments to 
determine study eligibility over a 28-day Screening period. Enrollment of patients with bone 
exclusive disease should be discussed and approved by the Sponsor’s Medical Monitor before 
enrollment (refer to inclusion criterion 5 in Section 4.1). For all patients, prior treatments and 
responses to such treatments, including radiological images and reports, within a year of study 
entry, will be collected as part of the medical history; for patients who are currently enrolled, 
this information will be collected retrospectively.
Starting on Cycle 1, Day 1, eligible patients will enroll into the study and receive AL101, 
either  4 mg intravenously (IV) weekly (QW) in Cohort 1 or 6 mg QW IV in Cohort 2, on 
Days 1, 8, 15, and 22 of each 28-day cycle until disease progression, unacceptable toxicity, or 
consent withdrawal. For patients with radiological progression, investigational treatment may 
be continued as long as the patient is having clinical benefit, is agreed to by the patient and 
physician and approved by the Sponsor’s Medical Monitor.

Paired tumor biopsies will be collected at screening (fresh or archival2 within 3 years) and on-
treatment at Cycle 4 Day 1 ±28 days (provided medically safe and not contraindicated). 
Samples will be sent to a central vendor for NGS analysis. Formalin-fixed paraffin embedded 
(FFPE) slides will be evaluated by IHC for NICD1 stain. On the day of the on-treatment 
biopsy, blood will also be drawn for PK and biomarker assessments.
During the Treatment period, patients will undergo radiographic assessments every 8 weeks 
(±3 days) for review by the Investigator. Scans will be collected and held for possible future 
retrospective evaluation by an Independent Central Review (ICR). Other assessments will be 
done as specified in the Schedule of Activities (SoA; Table 1), including safety exploratory 
biomarkers. A repeat of tumor imaging will be required for the purposes of confirmation of 
response (i.e., partial response, and/or complete response). The confirmation scan should be 
no earlier than 4 weeks following the first indication of response.
All patients will undergo end of study (EOS) visit 30 days post last treatment and will be 
contacted by phone every 3 months thereafter to determine survival status. In patients who 
discontinued investigational product due to toxicity, radiographic imaging will be done every 
3 months until disease progression or until the patient initiates another anti-cancer therapy.
Data Monitoring Committee (DMC) review: Throughout the study, the independent DMC 
will monitor safety and efficacy parameters at approximately quarterly intervals, after at least 
3 patients have been treated for at least 2 cycles (after the first on-treatment radiographic 
assessment). Further details are specified in the DMC charter.
Study Duration
Study participation for each patient consists of:
Screening period: 
up to 28 days
Treatment period: 
Weekly treatment until disease progression3, unacceptable toxicity, 
or consent withdrawal
EOS: 
30 days after the last administration of investigational product
Long-term follow-up: 
Every 3 months
Diagnosis and Main Criteria for Inclusion
Adult patients with histologically confirmed adenoid cystic carcinoma (ACC) who have:
2 If an archival tumor block or 25 unstained slides are not available, the patient will be required to have a fresh 
tumor sample obtained at screening.
3 For patients with radiological progression, investigational product may be continued as long as the patient is


Histologically confirmed ACC with known NOTCH 1/2/3/4 activating mutation that is 
recurrent or metastatic, not amenable to potentially curative surgery or radiotherapy.

Evidence of radiographic or clinical disease progression within 6-months of signing 
informed consent; newly diagnosed metastatic patients will be allowed.

At least 1 target lesion that is measurable per RECIST v1.1 for patients with nodal or 
visceral metastasis. Patients with bone exclusive disease will also be eligible after 
consultation and approval with Sponsor’s Medical Monitor before enrollment and only if 
bone lesions are evaluable and measurable by CT or MRI as per modified MD Anderson 
(MDA) Criteria (see Table 11 in Appendix C).
For full list of inclusion and exclusion criteria, please refer to Sections 4.1 and 4.2, respectively.
Investigational Product Route and Dosage Form
AL101 is a potent and selective inhibitor of gamma secretase-mediated Notch signaling. 
AL101 will be administered IV at the dose of 4 mg every 7 days (±2 day; QW) in Cohort 1 
and at the dose of 6 mg every 7 days (±2 day; QW) in Cohort 2 over 28-day cycles until 
disease progression, unacceptable toxicity, or consent withdrawal. For patients with 
radiological progression, investigational product can be continued as long as the patient is 
having clinical benefit, is agreed to by the patient and physician and approved by the 
Sponsor’s Medical Monitor. 
AL101 injection has been developed as a single-use sterile solution (1.2 mg/mL) for IV 
administration in clinical studies; each vial contains 5 mL (equivalent of 6 mg per vial). It is 
formulated as a sterile concentrate containing Cremophor® and ethanol and will be diluted 
with 0.9% Sodium Chloride Injection, USP (normal saline) or 5% Dextrose Injection, USP 
(D5W) to concentrations between 0.01 mg/mL and 0.06 mg/mL. In order to reduce the risk of 
infusion reactions caused by Cremophor, use premedication per institution guidelines such as 
H1- and H2-blockers (diphenhydramine and ranitidine or equivalents) or dexamethasone (refer 
to Section 7.1.2) will be given. For any questions, please contact the Sponsor’s Medical 
Monitor.
Statistical Methods
Null Hypothesis
A response rate of 8% or less is considered not clinically significant.
Sample Size
The study was initiated as a Simon’s two-stage optimal design. The study passed the futility 
analysis in Stage 1 of the Simon two-stage design and is currently continuing to enroll 
patients. While the data on Cohort 1 (4 mg QW) is maturing, the study will enroll up to a 
maximum of 45 patients in Cohort 1 and, in parallel, will be expanded with the addition of 
Cohort 2 (6 mg QW). The study will continue enrolling a total of 42 patients in Cohort 2, 
unless an unexpected safety signal emerges that in the judgement of the DMC requires 
analysis and/or poses a serious threat to the well-being of the patient. A second look is going

to be considered at 50% of the total information fraction (21 patients) for Cohort 2, with the 
study stopped for futility if two or fewer subjects respond .The expansion of Cohort 1 to a 
maximum of 45 patients and Cohort 2 to a maximum of 42 patients will provide at least 80% 
power in each cohort to test the hypothesis of achieving an increase of the response rate from 
8% to 25% using a type I error of 5%.
Analysis Population

Safety analysis set consists of all enrolled patients who received at least one dose of 
investigational product (even a partial dose).

Efficacy evaluable set includes all patients who receive investigational product and have 
at least one post baseline on-study assessment of tumor response.

Per-protocol (PP) analysis set consists of all efficacy evaluable patients without major 
protocol deviations, as defined by the Sponsor prior to database lock

PK analysis set includes all patients who receive investigational product and have at least 
one post baseline evaluable PK sample.
General Statistical Methods
Statistical analyses will be performed using SAS® v9.4 or higher (SAS Institute, Cary NC, 
USA).
Evaluation of data will consist primarily of descriptive summary statistics and data listings. 
Summary statistics for continuous variables will include the sample size (n), mean, standard 
deviation, median, minimum and maximum. Categorical variables will be summarized in 
frequency tables. Time to event variables will be analyzed using Kaplan-Meier methods.
If any statistical tests are performed, they will be one-sided, at the 5% significance level. 
Where confidence limits are appropriate, the confidence level will be 95%, unless otherwise 
stated.
Individual data (including relevant derived variables) will be presented by parameter in 
listings. Results of statistical analyses, descriptive summary statistics and supportive listings 
will also be presented.
Efficacy Analysis
Estimates of ORR and other response proportions will be presented together with 95% 
confidence intervals calculated using the Clopper-Pearson method. Kaplan-Meier estimation 
will be used for the analysis of time-to-event endpoints, including DOR, PFS, and OS. 
Primary efficacy analyses will be performed on the efficacy evaluable set. Refer to the SAP 
for more details.
Safety and Tolerability Analysis
Safety will be assessed on the basis of AEs, clinically significant laboratory abnormalities, 
concomitant medication use, vital signs, pain assessments, and physical examination data for 
patients in the safety analysis set.

Notes to Schedule of Activities:
All assessments to be performed pre-infusion unless stated otherwise.
Visit window will be ±2 days during treatment period, except for imaging ±3 days; EOS and Long-term follow-up will be ±7 days.
a.
Pre-screening assessments may be done while potential candidates are on other therapy provided that a separate pre-screening informed consent form is 
signed.
b.
For determining eligibility potential candidates will undergo a pre-screening assessment to confirm the presence of activating Notch mutations. Available 
genotyping results from a laboratory developed or commercially available NGS assay are acceptable. If historical genotyping results are not available, 
patient must sign prescreening ICF, and testing will need to be conducted during pre-screening using a laboratory developed or commercially available 
NGS assay. Available NGS test results will be shared in the Pre-identification form and response confirming activating Notch mutation is required before 
entering screening. Any newly characterized mutation (such as tandem duplication, variant allele frequency, variants of unknown significance, etc.), will 
be evaluated with the Sponsor on a case-by-case basis.
c.
Paired tumor biopsies (a resection, or core needle or punch biopsy with 20 gauge or larger and at least 2 passes) will be collected both at screening (fresh 
or archival within 3 years), and at Cycle 4 Day 1 ±28 days or earlier if the patient progressed(fresh sample, provided medically safe and not 
contraindicated). If an archival tumor block or 25 unstained slides are not available, the patient will be required to have a fresh tumor sample obtained at 
screening. Attempts should be made to biopsy lesions which are not considered to be “target lesions” per RECIST 1.1. criteria.
d.
Full physical examination at baseline; targeted physical examination at other time points.
e.
Complete blood count (CBC) includes hemoglobin, hematocrit, platelet count, WBC count, and absolute differential count.
f.
Chemistry includes glucose, blood urea nitrogen (BUN), creatinine, total bilirubin (a direct bilirubin should be obtained if the total bilirubin level is >1.5 
times ULN), albumin, AST (SGOT), ALT (SGPT), alkaline phosphatase (ALP), lactate dehydrogenase, electrolytes (sodium, potassium, chloride, calcium,

magnesium, and phosphorus. Creatinine clearance (CrCl) will be conducted at screening only; Calculation of CrCl will be based on acceptable  institution 
standard).
g.
Screening laboratory may be used if conducted within 3-7 days of CID1.
h.
Chemistry will be conducted every week for the first 3 cycles and then every 2 weeks, with the exception of liver function tests (AST/ALT/ALP/bilirubin) 
which will be done weekly until week 32, and then every 2 weeks thereafter.
i.
Coagulation factors will be done on Day 1 of every other cycle (e.g., C3D1, C5D1…).
j.
Urinalysis (specific gravity, pH, glucose, protein, ketones, and blood) performed at Screening and as clinically indicated.
k.
In the event of possible abnormal ECG findings, per the discretion of the investigator, additional ECG reads could be added at follow-up visits. The ECG 
evaluation will be performed centrally. Clinically significant ECG abnormalities will be recorded on the eCRF. Triplicate ECGs, at least 3 minutes apart, 
will be performed if QTcF is > 500 msec or if the Investigator identifies an ECG finding (for example QT interval prolonged or cardiac arrythmia) that is 
an adverse event and related to investigational product.
l.
Pre-menopausal female patients of childbearing potential only. Urine or serum pregnancy tests are acceptable.
m. CT or MRI with contrast, of the neck, chest, abdomen, and pelvis are acceptable (PET/CT is not allowed for study assessments, unless CT is done with 
IV contrast). Images will be repeated every 8 weeks (±3 days) during treatment period until disease progression. During the Long-term Follow-up visit, 
only in patients who discontinued investigational product due to toxicity, radiographic imaging will be done every 3 months until disease progression or 
until patient initiates another anti-cancer therapy. The same radiographic technique of each region must be used consistently throughout the study. Refer 
to Imaging Manual. A repeat of tumor imaging will be required for the purposes of confirmation of response (i.e., partial response, and/or complete 
response). The confirmation scan should be no earlier than 4 weeks following the first indication of response.
n.
Quality of life questionnaire will be administered every 4 weeks before investigational product administration or receipt of radiological imaging results
o.
For blood mRNA pharmacodynamic biomarker assessments, blood will be drawn on C1D1 and C1D22 at pre-dose (within 1 hour before start of dose), 7 
hours (±1 hour, and 24-48 hours after start of infusion (±1 hour), C1D8 pre-dose (within 1 hour before start of dose), C2D1 pre-dose (within 1 hour before 
start of dose), every odd cycle Day 22 pre-dose (within 1 hour before start of dose), and at confirmed progression.  In addition, a blood sample will be 
collected on the day of the on-treatment biopsy (Cycle 4, Day 1 ±28 days).
p.
For blood cfDNA biomarker assessments, blood will be drawn on C1D1 and C2D1 at pre-dose (within 1 hour before start of dose), and every odd cycle 
Day 22 pre-dose (within 1 hour before start of dose), and at confirmed progression. In addition, a blood sample will be collected on the day of the on-
treatment biopsy (Cycle 4, Day 1 ±28 days).

INTRODUCTION
1.1
THERAPEUTIC INDICATION
Adenoid cystic carcinoma (ACC) is a rare cancer most often occurring in the salivary glands 
with an incidence of 4.5 cases per million individuals (Lee, 2015; Moskaluk, 2013). The 
neoplasm can also arise in other locations, including the oropharyngeal and nasopharyngeal 
spaces, trachea, breast, lacrimal gland, skin, and lower female genital tract. ACC is characterized 
by an indolent but persistent course, with high rates of both local-regional recurrence and distant 
metastasis (Chae, 2015; Dillon, 2016; Ellington, 2012). Five, ten, and fifteen-year survival rates 
after surgical resection have been reported around 80%, 60%, and 45%, respectively, with almost 
half of patients dying from ACC, as opposed to other causes, at long-term follow-up (He, 2017; 
Lloyd, 2011).
Multiple studies have been conducted to discover genetic mutations and biomarkers specific for 
ACC (Ellington, 2012; Frierson, 2013). In addition to the frequent translocations involving 
myeloblastosis oncogene (MYB) in ACC, sequencing of tumor samples revealed genomic 
alterations in epigenetic modification (chromatin remodeling) pathway, DNA damage/ 
checkpoint pathway, FGF/IGF/PI3K signaling, and Notch signaling in a subset of patients (Ho, 
2013; Stephens, 2013). It was specifically demonstrated that NOTCH1 mutations significantly 
correlate with confirmed histology, advanced disease stage at diagnosis, higher incidence of liver 
and bone metastasis, and shorter relapse-free and overall survival (Ferrarotto, 2017; Sajed, 
2017).
1.2
CURRENT THERAPY
Most ACC primary tumors are treated with surgical resection and postoperative radiotherapy, yet 
local and repeated recurrences are common (Ellington, 2012). In advanced stage, conventional 
chemotherapy regimens are still utilized as first-line therapy although antitumor activity across a 
variety of chemotherapy classes is poor. Cisplatin and 5-FU or CAP (cisplatin, doxorubicin, and 
cyclophosphamide) regimens can be used as combination chemotherapy (Laurie, 2011; 
Papaspyrou, 2011). Agents commonly given as monotherapy include cisplatin, mitoxantrone, 
epirubicin, vinorelbine, paclitaxel, and gemcitabine. However, few of these agents have shown 
efficacy, highlighting the need for new therapeutic options (Chae, 2015; Ellington, 2012; Ko, 
2016). To date, no agent has been formally tested in ACC tumors that harbor Notch activation.
1.3
INVESTIGATIONAL THERAPY
AL101 is a potent and selective inhibitor of gamma secretase-mediated Notch signaling. The 
drug product is a single-use sterile solution (1.2 mg/mL) for intravenous (IV) administration.
Notch receptors are highly conserved, Type I transmembrane glycoproteins that regulate critical 
cellular functions, including differentiation, proliferation, self-renewal, survival, and cell fate 
determination. The Notch protein family has 4 members (Notch 1 to Notch 4) in mammals. 
Mammalian Notch receptors are activated by 4 transmembrane-bound ligands (Jagged1, 
Jagged2, Delta1, and Delta4 homologs) (LaFoya, 2016).

The Notch signaling pathway relies on regulated proteolysis. Upon ligand binding to the Notch 
receptor, a series of steps leads to cleavage by gamma secretase within the transmembrane 
domain. This frees the Notch intracellular domain (NICD), which translocates to the nucleus to 
form a transcriptional activation complex with the DNA-binding factor CSL (CBF1/Suppressor 
of Hairless/Lag1) and coactivators belonging to the mastermind-like family of proteins. Thus, a 
gamma-secretase inhibitor (GSI) such as AL101 can block the final step in Notch activation, the 
formation of the NICD.
1.3.1
Nonclinical Studies
The comprehensive battery of non-clinical studies conducted with AL101 included 
pharmacology studies, pharmacokinetic and metabolism studies in multiple species, and toxicity 
studies in rats and dogs.
In nonclinical models, AL101 exhibited antitumor/antiangiogenic activities including inhibition 
all 4 mammalian Notch receptors (Notch1 to Notch4) with high and equal potency. AL101 
exhibited broad-spectrum in vivo antitumor activity in nonclinical human cancer xenograft models 
of diverse histological types, including T-cell acute lymphoblastic leukemia and breast, non-small 
cell lung, pancreatic, and colorectal carcinoma, among others. AL101 exerted its antitumor activity 
through direct inhibition of cell proliferation and indirectly via inhibition of tumor angiogenesis.
In vitro genetic toxicity and safety pharmacology studies and in vivo single- and repeat-dose (up 
to 5-weeks duration) IV toxicity studies in rats and dogs (including safety pharmacology 
endpoints), were performed to evaluate the potential toxicologic profile of AL101. Collectively, 
the non-clinical toxicology studies have established a dose- and concentration-dependent safety 
profile for AL101 and its active metabolite, with effects that are primarily attributed to 
target-mediated Notch inhibition.
More detailed information is available in the AL101 Investigator’s Brochure (IB).

In Study CA216001, 94 patients were treated with AL101 (BMS-90692), of whom 83 patients 
received AL101 on a weekly (QW) schedule at doses ranging from 0.3 mg to 8.4 mg, and 11 
patients receiving AL101 every 2 weeks (Q2W schedule) at doses of 4 mg or 6 mg. The mean 
half-life (SD) following multiple-dose administration of AL101 over the 0.3-mg to 8.4-mg dose 
administered QW for at least 4 weeks ranged from 67.4 (18.7) hours to 147.8 (154.1) hours, 
indicating that AL101 is slowly eliminated. The most common reason given for discontinuation 
of treatment was disease progression, which was reported for 66 (70.2%) of patients in the study. 
Median duration of exposure was 5.9 weeks (range: 1 to 238 weeks) for the overall study 
population.
The primary endpoint was safety and establishment of recommended dose for Phase 2. Clinical 
safety data from Study CA216001 (N = 94) indicate that AL101 is tolerated at weekly doses of 
0.3 mg to 4 mg. Dose limiting toxicities (DLTs) were observed in the 6 mg dose level in 2 
patients (Grade 3 vomiting/Grade 3 lipase elevation and Grade 3 diarrhea) and 8.4 mg dose level 
in 3 patients (Grade 5 liver failure, recurrent Grade 3 hypersensitivity reaction and Grade 3 
vomiting, each of which occurred after 2 doses of AL101). The maximum tolerated dose (MTD) 
was defined as 4 mg for a QW dosing schedule and 6 mg for a Q2W dosing schedule (for more 
on dose selection details refer to Section 1.4.1). Most AEs have been Grade 1 or 2. The Grade 3 
to 4 related AEs occurring in at least 2 patients (out of 94) included hypophosphatemia (33 
patients, 35.1%)), diarrhea (18 patients , 19.1%)), hypokalemia (6 patients, 6.4%)), vomiting (4; 
patients, 4.3%)), aspartate aminotransferase increased (3 patients, 3.2%), dehydration (2 patients, 
2.1%), and hyponatremia (2 patients, 2.1%).
Best overall response assessed by the Investigator based on Response Evaluation Criteria In 
Solid Tumors criteria (RECIST) v1.1 showed preliminary evidence of AL101 clinical activity in 
2 metastatic ACC patients bearing NOTCH1 mutation who were treated with AL101 4 mg IV 
infusion once per week (QW) as follows:

First patient (63 years old male) had confirmed partial response (PR) with 
progressive disease at 8 months. Change from baseline in target lesion was 
23% decrease on Day 50 (8 weeks), 39% decrease on Day 113 (16 weeks), 
and 41% decrease on Day 162 (24 weeks).

Second patient (66 years old female) had stable disease at the first on-
treatment assessment: 2 mm decrease (5.7%) in target lesion on Day 53/8-
week assessment. Patient received 4 mg QW and at day 44 changed to 2.4 
mg QW; she discontinued treatment due to a non-treatment-related AE (at 
day 106).
In Study CA216002, preliminary evidence of clinical activity was observed in 3 patients, 2 with 
complete remission (resulting in allogeneic transplantation in 1 patient and ongoing >17 months 
in the other patient) and 1 patient with partial remission that lasted approximately 12 weeks, all 
at the 6 mg dose level (n = 20). In addition, previous data (December 2014) showed evidence of 
clinical activity (≥ 50% reduction in bone marrow blast percentage) in 8 (32%) of 25 patients, 
including 4 patients treated at the 4 mg dose and 4 patients treated at the 6 mg dose. On a weekly 
schedule, the 6-mg dose was tolerated in this population, and the expansion cohort was opened at 
this dose level.

In Study CA216003, for the more common tumor types, confirmed objective responses were 
reported for 8 of the 22 patients (36.4%) with TNBC (1 patient with a CR and 7 patients with 
PR) and 5 of the 19 patients (26.3%) with NSCLC (all with a PR). The most frequently reported 
AEs (>50% of all treated patients), regardless of causality, were fatigue, diarrhea, 
hypophosphatemia, nausea, and decreased appetite. Although there were limited numbers of 
patients in some treatment groups, the frequency of AEs appeared to be generally similar during 
QW administration of AL101 at a dose of 4 mg (Arms A, B, C) or 6 mg (Arms A, C) across all 
chemotherapy treatments.
In the current ACCURACY study, preliminary results have been reported. As of the cut-off date 
of August 31, 2019, data from 18 patients is included in the Efficacy Evaluable Analysis set. 
Among the 18 patients who had at least one follow-up radiological examination, the investigator 
assessment of best response based on RECIST v1.1 or modified MDA bone response criteria was 
PR in 4 patients (22%), SD in 7 patients (39%) and PD in 7 patients (39%); disease control rate 
(PR+SD) was 61% (11 patients) (Ferrarotto, 2019). The longest response duration is over 5 
months and ongoing and the longest SD is over 7 months and ongoing. As of October 11, 2019, 
the safety analysis set included 29 patients. Overall, 23 patients reported at least 1 TEAE. 
CTCAE Grade 1 were reported by 3 patients (10.3%), Grade 2 by 6 patients (20.7%), Grade 3 by 
31% (9 patients); Grade 4 by 3 patients (10.3%) and Grade 5 by 2 patients (6.9%). The most 
frequently reported AEs (>30% of all treated patients), regardless of causality, were nausea, 
fatigue, diarrhea and vomiting. SAEs were reported for 14 patients (48.3%) with pneumonia 
reported by 3 patients (10.3), all other events were single incidences. Treatment-related SAEs 
included infusion site reactions (2 reactions in one patient) and keratoacanthoma (each, 1 patient, 
3.4%).
The observed safety profile of AL101 in the ACCURACY study to date suggests a lower rate of 
adverse events of Grade 3 and above than previously reported for AL101 Phase 1 studies 
conducted by the previous developer. Notably, using the toxicity management guidelines for 
gastrointestinal (GI) adverse events in this protocol (outline in Section 6.6), the rate of Grade 3 
diarrhea was reduced to 3.4% vs. 19.1% in the ongoing ACCURACY study and study 
CA216001, respectively.
Based on results of study CA216001 for AL101 monotherapy, the previous developer 
recommended that the MTD for a QW dosing schedule was 4 mg, and for Q2W dosing schedule 
was 6 mg. In Study CA6216002 for AL101 monotherapy in T-ALL and T-LL, the prior 
developer concluded 6 mg QW was tolerated in that patient population. The previous developer 
decided to discontinue development of AL101 due to business reasons and not due to any safety 
concerns associated with the use of AL101.
This suggest that although the MTD in the solid tumor population treated on a QW dosing 
schedule was recommended by previous developer of AL101 to be 4 mg QW, however, with a 
rigorous control of GI toxicity as shown CA216002, a dose of 6 mg is safe to administer to 
patients suffering with advanced cancer.

STUDY RATIONALE
AL101 is a potent and selective inhibitor of gamma secretase-mediated Notch signaling that is 
currently under development as an antitumor/antiangiogenic agent for single use or in 
combination with other targeted agents in the treatment of tumor growth and metastasis. A large 
body of experimental evidence supports the causal role of Notch pathway deregulation in 
tumorigenesis (Braune, 2016; Previs, 2015; Vinson, 2016; Wang, 2015; Xiao, 2016; Zhao, 
2017). In ACC, sequencing of tumor samples revealed genomic alterations in the Notch1 
pathway in a subset of patients with a distinct ACC phenotype. ACC patients with NOTCH1 
mutations have an aggressive disease with a distinct pattern of metastasis and worse prognosis 
(Ferrarotto, 2017). In addition to NOTCH1 mutations, other NOTCH mutations (2, 3, 4) were 
identified in ACC (Bell, 2014; Sant, 2017; Stoeck, 2014).
The effect of AL101 was evaluated in four ACC Patient Derived Xenografts (PDX) models that 
utilize tumors derived directly from patients have become the best platform for screening and 
predicting drug efficacy in oncology nonclinical models. These tumors, that are transferred 
directly to mice, without tissue culturing, maintain the histopathological and molecular features 
and best mimic the original human cancer (Izumchenko, 2017).
The effect of AL101 was evaluated prospectively in tumors with wild type Notch versus tumors 
with Notch activating mutations. Seventy milligrams of tumor tissue were implanted into 
Athymic Nude female mice 6-12 week old (Treatment arm N=5, Control arm N=10). 
Randomization to study arms was done once tumors reached a volume of 150-300 mm3. Dosing 
regimen was 7.5 mg/kg AL101 po weekly, 4 days on/ 3 days off. Tumor volumes were measured 
twice a week.
Tumor growth inhibition (TGI) was significantly higher with AL101 monotherapy, compared to 
vehicle in both Notch mutant models (ACCx9: 110% TGI P<0.0001; and ACCx11: 78% TGI 
P=0.0441). AL101 did not have a significant effect in models without Notch activating mutations 
(ACCx6: 37% TGI P>0.99; ACCx5M1: 60% TGI P=0.25 (Figure 1).

Based on a preliminary Phase 1 study with AL101 (CA216001) where clinical activity of AL101 
was shown in an unselected patient population with solid tumors (see Section 1.3.2), the current 
study is designed to evaluate the efficacy and safety of AL101 in patients with ACC bearing 
activating Notch mutations.
The preliminary results of this study (see Section 1.3.2) suggest that the patient population 
initially recruited into this study had advanced progression, more than expected based on 
literature review (Ferrarotto, 2017; Ho, 2019). Thus, with the addition of Cohort 2, the Sponsor 
will now evaluate the biological activity in a larger patient population to better understand the 
response rate and the nature of the response as well as define the patients who are likely to 
respond to the drug in future studies.
1.4.1
Dose Selection
The doses selected for this study, 4 mg QW (Cohort 1) and 6 mg QW (Cohort 2) are based on 
nonclinical studies, prior clinical studies conducted by BMS (the previous developer) 
(CA216001, CA216002 and CA216003) and preliminary outcome from the ongoing 
ACCURACY study. Please also refer to the IB for further information.
In Study CA216001, in dose escalation on a QW schedule, patients were treated at AL101 dose 
levels of 0.3 (n = 4), 0.6 (n = 3), 1.2 (n = 4), 2.4 (n = 4), 4 (n = 7), 6 (n = 14), and 8.4 mg (n = 
11). In study CA216001, AL101 was safe and tolerated in doses up to 4 mg QW administration. 
DLTs were observed in the 6 mg and 8.4 mg dose levels. As AL101 potentially contributed to 
these DLTs and no DLTs were reported in the 7 DLT-evaluable patients treated at this dose in 
the dose escalation phase, the MTD in the solid tumor population treated on a QW dosing 
schedule as was recommended by the previous developer of AL101 to be 4 mg.
Overall, 43 patients were treated at a dose of 4 mg QW, in either the dose escalation (N=7) or 
dose expansion (N=36) phases. Treatment-related ≥Grade 3 AEs included hypophosphatemia

(41.9%; 18/43), diarrhea (18.6%; 8/43), hypokalemia (7.0%; 3/43), and anaphylactic reaction, 
anemia, AST increased, nausea, pruritus, and vomiting (2.3% each; 1/43).
PK results from Study CA216001 indicate that AL101 exposure (Cmax and AUC) increases 
approximately linearly for QW dosing from 4 mg to 6 mg.
PD results (Hes1 expression in PB) from Study CA216001 indicate greater maximum effect and 
duration of target inhibition when increasing the QW dose from 4 mg to 6 mg. Mean Hes1 
inhibition is maintained greater than 50% throughout 7 day period at 6 mg, where it recovers to 
under 50% by day 7 at 4 mg.
Based on the observed safety profile of AL101 in this study to date (see Section 1.3.2), the 
existing toxicity management guidelines (outlined in Section 6.6) for GI and liver toxicity (liver 
function test to be monitored weekly; refer also to Sections 8.4.1 and 8.4.5 for liver-related 
adverse event of special interest) and the totality of the data from all 3 Phase 1 studies (see 
Section 1.3.2) as well as the enhanced PD modulation at 6 mg QW, the Sponsor decided to add a 
cohort with AL101 dose of 6 mg QW (Cohort 2); this dose may offer patients an increased 
benefit (as evident by PK/PD data described above) while maintaining their safety with weekly 
visits and rigorous toxicity management guidelines. Notably, using the toxicity management 
guidelines for GI adverse events, the rate of Grade 3 diarrhea was reduced to 3.4% in the 
ongoing ACCURACY study.

STUDY DESIGN 
This is a Phase 2, non-comparative, open-label, multicenter study of AL101 in patients with 
recurrent or metastatic ACC who harbor NOTCH 1,2,3,4 activating mutations.
The study includes 2 cohorts, ran in a sequential fashion:

Cohort 1 – AL101 4 mg once weekly (QW) intravenously (IV)

Cohort 2 – AL101 6 mg QW IV
Cohort 1 will continue to enroll to reach up to a maximum of 45 patients. Cohort 2 will open for 
enrollment up to a maximum of 42 patients. Prior to entering the study, to determine eligibility, 
potential candidates will undergo pre-screening assessment and confirmation for the presence of 
activating Notch mutations. Available mutation status from prior tests with any commercially 
available or locally developed NGS assay are acceptable. In Europe any commercially available 
CE marked device shall be used (for country specific requirements refer to Appendix E.
If historical genotyping results are not available, testing will need to be conducted during pre-
screening using a laboratory developed or commercially available NGS assay to identify and 
confirm an activating Notch mutation. Any newly characterized mutation (such as tandem 
duplication, variant allele frequency, variants of unknown significance, etc.), will be evaluated 
with the Sponsor on a case-by-case basis. Pre-screening study-specific assessments may be done 
while potential candidates are on other therapy provided that a separate pre-screening informed 
consent form is signed.
Patients with activating Notch mutations will then undergo screening assessments to determine 
study eligibility over a 28-day Screening period. Enrollment of patients with bone exclusive 
disease should be discussed and approved by the Sponsor’s Medical Monitor before enrollment 
(refer to inclusion criterion 5 in Section 4.1). For all patients, prior treatments and responses to 
such treatments, including radiological images and reports, within a year of study entry will be 
collected as part of the medical history; for patients who are currently enrolled, this information 
will be collected retrospectively.
Starting on Cycle 1, Day 1, eligible patients will receive AL101, either 4 mg QW IV in Cohort 1 
or 6 mg QW IV in Cohort 2, on Days 1, 8, 15, and 22 of each 28-day cycle until disease 
progression, unacceptable toxicity, or consent withdrawal. For patients with radiological 
progression, investigational product may be continued as long as the patient is having clinical 
benefit, is agreed to by the patient and physician and approved by the Sponsor’s Medical 
Monitor. 
Paired tumor biopsies will be collected at screening (fresh or archival5 within 3 years) and on-
treatment at Cycle 4 Day 1 ±28 days provided medically safe and not contraindicated. Samples 
will be sent to a central vendor for NGS analysis. Tumor Formalin-fixed paraffin embedded 
5 If an archival tumor block or 25 unstained slides are not available, the patient will be required to have a fresh 
tumor sample obtained at screening.

(FFPE) slides will be evaluated by IHC for NICD1 stain. On the day of the on-treatment biopsy, 
blood will also be drawn for PK and biomarker assessments.
During the Treatment period, patients will undergo radiographic assessments every 8 weeks 
(±3 days) for review by the Investigator. Scans will be collected and held for possible future 
retrospective evaluation by ICR. Other assessments will be done as specified in Schedule of 
Activities (SoA; Table 1), including safety and exploratory biomarkers.
A repeat of tumor imaging will be required for the purposes of confirmation of response (i.e., 
partial response, and/or complete response). The confirmation scan should be no earlier than 4 
weeks following the first indication of response.
All patients will undergo end of study (EOS) visit 30 days post last treatment and be contacted 
by phone every 3 months to determine survival status. In patients who discontinued 
investigational product due to toxicity, radiographic imaging will be done every 3 months until 
disease progression or until patient initiates another anti-cancer therapy.
Study participation for each patient consists of:
Screening period: 
up to 28 days 
Treatment period: 
Weekly treatment, until disease progression6, unacceptable 
toxicity, or consent withdrawal
EOS: 
30 days after the last administration of investigational product. 
Long term follow-up: 
Every 3 months.
6 For patients with radiological progression, investigational product may be continued as long as the patient is 
having clinical benefit, is agreed to by the patient and physician and approved by the Sponsor’s Medical Monitor.

SCREENING FAILURES
Patients who fail to meet the entrance criteria at any time during the Screening period are defined 
as screen failures. All screen failures will be recorded on the screening failure log, which 
documents the site number and screening number and reason(s) for screen failure. The screening 
failure log will be kept in the Investigator’s Site File.
Re-screening/re-assessment outside the Screening period will be possible on a case-by-case basis 
following Sponsor approval. Patients allowed to be re-screened will be assigned a new screening 
number (with referral in eCRF to the previous screening number); such patients will be 
determined a screen failure after the second screening confirmed the patient is ineligible.
4.5
EARLY WITHDRAWAL OF PATIENTS FROM THERAPY OR ASSESSMENT
Patients are free to discontinue their participation in the study at any time and without prejudice 
to further treatment. The Investigator must withdraw any patient from the study if that patient 
requests to be withdrawn, or if it is determined that continuing in the study would result in a 
significant safety risk to the patient.
Discontinuation or interruption of investigational product does not represent withdrawal from the 
study. Patients may withdraw or be withdrawn from investigational product at any time.
Patients who permanently discontinue investigational product or are withdrawn from the study 
for non-safety reasons prior to the first efficacy endpoint (i.e., upon 2 cycles of treatment) may 
be replaced.
Dosing of investigational product must be interrupted for any serious adverse reactions assessed 
by the investigator as related to investigational product. Restart of dosing may be considered 
upon approval by the Sponsor’s Medical Monitor (or designee) after resolution of IP treatment-
related events to baseline. 
Please refer to Section 6.6 for AL101 dose modifications and toxicity management which may 
lead to investigational product discontinuation. Pregnancy is a mandatory criterion for permanent 
discontinuation of investigational product. Any patient being managed with dose interruption for 
toxicity should have their study assessments followed per SoA.
The patient’s participation in the study may be discontinued due to the following reasons:

Request of Investigator

Life-threatening event or death

Patient withdrew consent

Patient is lost-to-follow-up
The patient may discontinue investigational product due to the following reasons:

Request of the Investigator


EFFICACY ASSESSMENTS
5.1.1
RECIST v1.1
The primary efficacy endpoint, ORR, will be evaluated using RECIST v1.1 (Eisenhauer, 2009) 
as described in Appendix C (For patients with bone-exclusive disease, the modified MDA bone 
criteria will be used to access response; see Table 11 for response criteria for bone metastases). 
A repeat of tumor imaging will be required for the purposes of confirmation of response (i.e., 
partial response, and/or complete response). The confirmation scan should be no earlier than 4 
weeks following the first indication of response.
In addition to local imaging assessments performed by the Investigator, scans will be sent to 
central imaging for possible future reads.
The central imaging read is being conducted for regulatory purposes only. The Investigator is 
responsible for diagnostic and treatment decisions concerning their patients.
The process for image collection and transmission to the ICR during the study can be found in 
the Imaging Manual.
Disease staging will be collected at diagnosis and Screening for this protocol, prior to any 
treatment initiation. The minimum duration of stable disease will be defined as  4 weeks in 
determining the best overall response. To document evidence of prior disease progression, tumor 
measures prior to baseline assessments may be requested by the Sponsor.
The imaging requirements are provided in Table 2.

Patient Reported Outcome: European Organization for Research and Treatment 
of Cancer Quality of Life Questionnaire 30 questions (EORTC QLQ-C30)
The EORTC QLQ-C30 will be administered during the study at screening and then every 4 weeks 
before investigational product administration.
EORTC QLQ-C30 was developed as an instrument to measure cancer patients’ physical, 
psychological and social functions (Kaasa, 1995). The questionnaire is composed of 5 multiitem 
scales (physical, role, social, emotional and cognitive functioning) and 9 single items (pain, 
fatigue, financial impact, appetite loss, nausea/vomiting, diarrhea, constipation, sleep disturbance 
and quality of life) (Kyriaki, 2001). It is validated and reliable and has been used successfully in 
various types of cancer, including head and neck cancer (Bjordal, 2000; Chaukar, 2005).
The example of the English version of the EORTC QLQ-C30 can be found at Appendix D and at 
this link:

informed consent signing through EOS visit (30 days following cessation of investigational 
product) (see Section 8.1).
5.2.2
Adverse Events of Special Interest
Adverse event of special interest (AESI) will be assessed and recorded at all study visits 
throughout the study from baseline through EOS visit (30 days following cessation of 
investigational product). For details see Section 8.4.
5.2.3
Medical History and Concomitant Medications
Any clinically significant diseases in the prior 3 years including any co-morbid conditions 
requiring active treatment as well as significant surgeries will be documented in the medical 
history section of the eCRF. This includes prior medical history and treatment regimen for ACC.
Abnormal physical examination finding and/or the diagnosis of concomitant disease resulting 
from assessment at Screening must also be documented in the medical history section.
Information on all interventions (systemic therapy, surgery, radiation treatment) related to the 
patient’s cancer will also be collected. Radiology and photography reports from imaging 
conducted as routine care will be collected if available from the last 3 years.
Concomitant medication is defined as any prescription or over-the-counter preparation, including 
vitamins and supplements. Use of concomitant medication from 28 days before Day 1 of Cycle 1 
through 30 days after the last dose of investigational product must be recorded onto the eCRF

Vital signs
Vital signs will be measured at all study visits and will include heart rate, respiratory rate, 
temperature, and blood pressure (systolic and diastolic). Blood pressure and heart rate will be 
done at rest as per standard practice at the investigational site. Significant findings noticed after 
the start of investigational product and findings that worsen significantly, which meet the 
definition of an AE must be recorded on the AE eCRF.
5.2.6
ECG
Single 12-lead ECG will be obtained using a centrally provided calibrated ECG machine that 
automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals. Triplicate 
ECGs, at least 3 minutes apart, will be performed if QTcF is > 500 msec or if the Investigator 
identifies an ECG finding (for example QT interval prolonged or cardiac arrythmia) that is an 
adverse event and related to investigational product. Additional timepoints may be added, as 
clinically indicated.
Patients should be in the supine position after the patient has rested for at least 5 minutes. In the 
event of possible ECG findings, additional ECG reads could be added at follow-up visits. The

All safety laboratories, hematology, chemistry and urine analysis are to be drawn by standard 
phlebotomy techniques, into the site prescribed appropriate tubes for the specific tests and 
amounts prescribed by local laboratory, e.g., CBC with differential 5 ml in a purple top tube., 
chemistry 10 ml in a red top tube. Refer to the Laboratory Manual for further details on specimen 
collection and handling procedures.
5.2.9
Pregnancy Test
Women of childbearing potential will have a urine or serum pregnancy test at timepoints 
designated in the SoA.
5.3
POPULATION PHARMACOKINETICS
Blood samples for population pharmacokinetics (PK) will be obtained at the times designated in 
the SoA, footnote q (Table 1). Start- and end-time for each investigational product infusion (and 
any interruptions) will be recorded in the eCRF. The actual time of the sample collection will be 
recorded in the eCRF. All samples will be analyzed for both parent and metabolite using liquid 
chromatography with tandem mass spectrometry (LC-MS/MS) assay.
A population (mixed-effects) approach will be used to analyze the concentration data, the goal 
being to obtain a set of population parameters and to identify covariates that affect systemic 
exposure to each of the parent and metabolite. For each of parent and metabolite, one- and two-
compartment linear models will be applied to the data. If graphics suggest that these models are 
not appropriate, other models such as those including non-linearity with respect to dose and/or 
time will be evaluated. The relationship of pharmacokinetic parameters to body size will be 
evaluated systematically. Other covariates will be considered for inclusion in the model based on 
graphics. Models will be selected based on graphics and changes in the objective function. The 
analysis will be conducted with NONMEM software.
For more details on instructions for collecting PK samples, refer to the Study PK Manual.
5.4
BIOMARKERS
Notch mutational status from prior tests with any commercially available NGS assay kit or as 
assessed at enrollment by institutional NGS test will be confirmed centrally. In Europe any 
commercially available CE marked device shall be used (for country specific requirements refer

Stipulations for Tumor Biopsy
Patients must agree to provide two separate tumor biopsies, at screening and on-treatment at 
Cycle 4 Day 1 ±28 days (or earlier if the patient progressed). On-treatment biopsies do not need 
to be done if either the site investigator or person performing the biopsy judges that no tumor is 
accessible for biopsy or that biopsy poses too great of a risk to the patient. (If the only tumor 
accessible for biopsy is also the only lesion that can be used for RECIST v1.1 response 
evaluation, then the patient may be exempt from biopsy after discussion with the Sponsor).

Frequency: Weekly (QW) on Days 1, 8, 15 and 22 of each 28-day cycle)
Route of 
Administration
AL101 will be administered using an IV infusion pump over 60 minutes; time 
windows of -5 minutes to +10 minutes are permitted. The connection between the 
tubing from the infusion pump to the patient should be close to the insertion of 
the intravenous catheter.
The exact duration of infusion should be recorded in both source documents and 
eCRFs. The start time of dose administration will be called “0” hour. If an 
infusion is extended, interrupted or discontinued prior to completion, the duration 
and the reason for any dose extension, interruption or discontinuation will be 
recorded in the eCRF.
Preparation
Cohort 1: Prior to IV administration, the drug product is diluted 3.3 mL (use 5mL 
syringe) in a 250 mL infusion bag of 0.9% Sodium Chloride Injection, USP 
(normal saline) or 5% Dextrose Injection, USP (D5W).
Cohort 2:  Prior to IV administration, the drug product is diluted 5.0 mL (use 
5 mL syringe) in a 250 mL infusion bag of 0.9% Sodium Chloride Injection, USP 
(normal saline) or 5% Dextrose Injection, USP (D5W).
Only diethylhexyl phthalate-free bags and sets can be used to administer 
solutions. Aseptic practices should be followed when handling, preparing, and 
administering the infusion solutions because the drug vial does not contain 
antibacterial preservatives or bacteriostatic agents. A sufficient excess of drug 
product is included in each vial to account for withdrawal losses.

DOSE MODIFICATION AND TOXICITY MANAGEMENT GUIDELINES
Dose modification associated with AL101 is described below in Table 6.
The causality assessment system proposed by the World Health Organization Collaborating 
Centre for International Drug Monitoring, the Uppsala Monitoring Center (WHO-UMC)9 will be 
used by the Investigator for assessing drug-related (certain, probable/likely, possible) 
non-hematological Grade 3  (except isolated Grade 3 electrolyte abnormality that are not 
associated with clinical signs or symptoms and are reversed with appropriate medical 
intervention within 48 hours) and hematological Grade 4 toxicities will lead to a 1 dose level 
reduction for AL101. For easily manageable Grade 1 or 2 toxicity, no dose reductions are 
required, but careful observation and treatment is required. Dose modification of intolerable 
Grade 2 toxicity will be evaluated on a case-by-case basis with the Sponsor. Re-escalation of the 
dose following a dose reduction is allowed only after discussion and approval of the Sponsor’s 
Medical Monitor. Maximum AL101 treatment interruption allowed is 28 days; treatment 
interruption longer than 28 days will result in discontinuation of patient from the study. 
Additional treatment guidelines may be implemented by the Investigators, with agreement of the 
Sponsor/Medical Monitor, as needed to ensure patient safety.

6.6.1
Treatment of Infusion Reactions
In case of hypersensitivity reactions, the Investigator should institute treatment measures 
deemed medically appropriate in accordance with current medical practice and treatment 
guidelines. The following treatment recommendations are based on prior experience with 
Taxol (containing Cremophor)10; these and/or other measures deemed medically necessary 
should be implemented based on the judgment of the Investigator. To reduce the risk of 
infusion reactions caused by Cremophor, premedication with H1- and H2-blockers 
(diphenhydramine and ranitidine or equivalents) or dexamethasone (Refer to Section 7.1.2 for 
additional instructions on premedication with steroids) will be given.
Note that the “Grades” listed below do not correspond to NCI CTCAE v5.0 criteria (which are 
based on response to intervention, and thus are not used here to recommend specific 
interventions). For the purpose of AE reporting and for determining the need for dose 
modifications, NCI CTCAE v5.0 grading for allergic reaction should be used.

Grade 1 allergic reaction/hypersensitivity (e.g., transient flushing, rash, drug 
fever < 38°C):

Supervise at the bedside.

Report to Sponsor as an adverse event of special interest (AESI)

Grade 2 allergic reaction/hypersensitivity (e.g., urticaria, drug fever  38°C, 
rash, flushing, dyspnea):

Interrupt the infusion and disconnect infusion tubing from patient,

Administer IV antihistamines (diphenhydramine 25 to 50 mg), and ranitidine,

After recovery from symptoms, resume the infusion at a half of the infusion rate and if 
no further symptoms appear, complete the administration of the dose. A target infusion 
time of up to 3 hours may be appropriate in many cases.

Report to Sponsor as an AESI

Grade 3 or 4 allergic reaction/hypersensitivity (e.g., symptomatic bronchospasm 
requiring parenteral medication(s) with or without urticaria; allergy-related 
edema/angioedema; anaphylaxis; hypotension):

Stop the infusion and disconnect infusion tubing from patient,

Administer epinephrine, antihistamines, and nebulized bronchodilators as medically 
indicated,

Consider IV steroids which may prevent recurrent or ongoing reactions,

Report to Sponsor as a serious adverse event (see Section 8.2),

Also report to Sponsor as an AESI

6.6.2
Guidelines for Management of Diarrhea
The following are guidelines for the management of diarrhea and are not meant to replace the 
clinical judgment of the Investigator / treating physician(s) or an institutional diarrhea 
management protocol which adheres to most current medical standards.
1. Treat with loperamide
Loperamide should be started at the earliest sign of (1) a poorly formed or loose stool, (2) the 
occurrence of 1 to 2 more bowel movements than usual in 1 day, or (3) an increase in stool 
volume or liquidity. Loperamide may be taken in the following manners: 4 mg at the first onset 
of diarrhea, then 2 mg every 2 hours around-the-clock until diarrhea free for at least 12 hours. 
Patients may take loperamide 4 mg every 4 hours during the night. This dosing regimen is 
higher than the standard dose of loperamide, but is typical for the treatment of diarrhea caused 
by anticancer therapy (Real, 2009). These doses should not be used for more than 48 hours due 
to the risk of paralytic ileus. Patients should be provided with loperamide at the initial 
treatment visit so that they have sufficient supply on hand in case antidiarrheal support is 
required. It is important that loperamide is taken as instructed, as some cases of higher-grade 
diarrhea have occurred in patients not taking the maximum doses, and these cases have 
improved after loperamide was taken more frequently. For patients who cannot tolerate 
loperamide or do not get adequate relief with maximum doses, standard doses of LOMOTIL® 
(diphenoxylate/atropine) may be added or used instead of loperamide. Additional antidiarrheal 
measures, such as octreotide, may be used at the discretion of the Investigator or treating 
physician.
2. Interrupt AL101 dosing
For Grade 2 or higher diarrhea that is not controlled (i.e., to Grade 1) with loperamide, dosing 
of AL101 should be interrupted, as continued dosing is likely to result in increased severity of 
diarrhea. In addition, evaluation of infectious causes should be considered. Based on the 
mechanism of action and preliminary clinical experience, full gastrointestinal (GI) tract 
recovery will likely take longer than the time for diarrhea to resolve. Thus, interruption for 5 
days to 7 days beyond the resolution of diarrhea should be considered. Depending on the 
severity, time to onset, and time to resolution of diarrhea, reduction of AL101 dose and/or 
frequency, omission of future doses, or dexamethasone co-administration should be considered.
3. Increase fluid intake and, if applicable, consider stopping antihypertensive therapy 
and nonsteroidal anti-inflammatory drugs
Hypotension and/or renal insufficiency can occur in the setting of volume depletion from 
severe diarrhea. At the onset of any diarrhea, patients should be instructed to increase fluid

Confidential
intake to help maintain fluid and electrolyte balance during episodes of diarrhea. Parenteral 
hydration should be started if oral hydration is not sufficient. The investigator should consider 
interrupting antihypertensive therapy and nonsteroidal anti-inflammatory drugs, if medically 
appropriate.
4. Treat with dexamethasone
For Grade 2 or higher diarrhea that is not adequately controlled with loperamide and dose 
interruption, administration of dexamethasone may be considered at the discretion of the 
treating physician/investigator. In nonclinical models of other GSIs, coadministration of 
dexamethasone has been shown to decrease the severity of intestinal pathology.(Real, 2009; 
Wei, 2010). Dexamethasone may be administered per os (PO) or IV, as appropriate. As there is 
no reported human experience with the use of dexamethasone for this indication, it is not 
known whether this effect will occur in humans at achievable exposures of dexamethasone. In 
a small number of cases, administration of dexamethasone 8 mg to 10 mg daily, followed by 
tapering over several days, may have contributed to the improvement of diarrhea. If, in the 
judgment of the investigator, it is in the patient’s best interest to receive additional treatment 
with AL101 (for example, the patient has a response to therapy), dexamethasone co-
administration with future doses may be used after discussion with the Sponsor/medical 
monitor. In such cases, dexamethasone 8 mg to 10 mg daily for 2 days to 3 days, beginning on 
the day of AL101`dosing followed by tapering over several days, may be appropriate.
For diarrhea associated with signs of colitis (e.g., fever, peritoneal signs, or significant GI 
bleeding), administration of dexamethasone and antibiotics should be considered. Also, 
inpatient hospitalization, bowel rest, and radiological evaluation may be appropriate if there are 
signs of possible intestinal perforation.

STUDY RESTRICTIONS
7.1
PRIOR AND CONCOMITANT THERAPY
7.1.1
Premedication to Prevent Hypersensitivity Reaction
Histamine is a major mediator of anaphylactic/anaphylactoid responses in man, such as those 
induced by Cremophor EL, an excipient in AL101. The premedication regimen below is based 
on clinical experience with other compounds containing Cremophor EL.
In order to prevent a hypersensitivity reaction, all patients initiating AL101 treatment will be 
premedicated approximately 1 hour prior to the infusion of AL101 with the following regimen:

H1-blocker (for example, diphenhydramine 25 to 50 mg oral or equivalent), and

H2-blocker (for example, famotidine 20 to 40 mg oral or equivalent).
For patients who remain on study for more than 4 doses of AL101 without any evidence of 
infusion-related reaction, modification of the premedication regimen may be considered at the 
discretion of the investigator, with notification of the Sponsor’s Medical Monitor. At this time, 
1 of the 2 histamine blockers may be discontinued; if there is still no evidence of infusion-
related reaction with the next 2 doses of AL101, the other may be discontinued. If under this

discontinuation plan, the patient has an infusion-related reaction resulting in medical treatment, 
premedication with H1- and/or H2-blockers (as appropriate) should be resumed for subsequent 
doses.
If a patient experiences a Grade 3 or 4 infusion-related reaction despite pretreatment with the 
H1- and H2-blockers then the patient, if re-treated, should also be premedicated with 
corticosteroids (as described in Section 7.1.2) in addition to the H1- and H2-blockers). In the 
event that a patient has a repeat Grade 3 or 4 infusion-related reaction despite premedication 
with H1- and H2-blockers and steroid, the patient must not receive any further treatment with 
AL101, unless agreed by the Sponsor/Medical Monitor and investigator that it is in the 
patient’s best interest to continue treatment (e.g. patient has had a response to therapy) and 
appropriate safety measures can be implemented. Such measures may include dose reduction, 
increased infusion time, initial lower infusion rate with gradual increases, and/or premedication 
with multiple doses of dexamethasone. These measures have been used to allow re-treatment 
after infusion reactions with other agents, including IXEMPRA and Taxol (Peereboom, 1993).
7.1.2
Premedication with Corticosteroids
All patients will receive premedication with corticosteroids as prophylaxis utilizing the 
approximately following regimen.

8 mg dexamethasone Per Os (PO) the night before each infusion

8 mg dexamethasone PO or IV within 30 minutes prior to dosing

8 mg PO every 8 hours for an additional 4 doses starting about 4 to 8 hours after the 
infusion is finished

Repeat for the first 4 doses (first cycle).
If there are no GI toxicities following the first 4 infusions, the number of additional doses 
following the future infusions can be decreased from 4 to 2 doses of 8 mg PO every 8 hours.
Further tapering should only be considered if, in the opinion of the investigator, steroid side 
effects are an issue and after discussion with the Sponsor’s Medical Monitor.
Other steroids, such as budesonide or prednisone may be used utilizing “prednisone 
equivalent” conversions.
7.1.3
Allowed Medications
All treatments that the Investigator considers necessary for a patient’s welfare may be 
administered at the discretion of the Investigator in keeping with the community standards of 
medical care. All concomitant medication will be recorded on the eCRF including all 
prescription, over-the-counter (OTC), herbal supplements, and IV medications and fluids. If 
changes occur during the study period, documentation of drug dosage, frequency, route, and 
date may also be included on the eCRF.
All concomitant medications received within 28 days before the first dose of investigational 
product and 30 days after the last dose of investigational product should be recorded.

therapies for ACC should be recorded.
Allowed concomitant therapies:

Glucocorticoids may be administered for treatment of infusion reaction and as 
premedication to prevent further infusion reaction (maximum daily dose of prednisone or 
equivalent ≤ 10 mg/day).

In Cohort 2, in case of toxicity (e.g., GI AEs), per discretion of the Investigator and in 
consultation with the Sponsor’s Medical Monitor, dexamethasone (Refer to Section 7.1.2) 
will be permitted.

Palliative radiation therapy to a limited field (e.g., painful bone metastasis, painful lumps), 
if it is not the sole site of measurable and/or assessable disease, is allowed any time 
during study participation with prior approval of the Sponsor’s medical monitor.

Patients with castration resistant prostate cancer who have not undergone surgical 
orchiectomy can continue on medical therapies (i.e., gonadotropin releasing hormone 
[GnRH] analogs) to maintain castrate levels of serum testosterone. Concurrent treatment 
with ketoconazole or anti-androgens is not permitted, and patients who have discontinued 
these medications must have a washout period of at least 4 weeks or 5 half-lives of the drug 
(whichever is longer) prior to the first dose of investigational product.
7.1.4
Prohibited Concomitant Medication
Medications specifically prohibited in the exclusion criteria are not allowed during the ongoing 
study. If there is a clinical indication for any medication or vaccination specifically prohibited 
during the study, discontinuation from study therapy or vaccination may be required. The 
Investigator should discuss any questions regarding this with the Sponsor’s Medical Monitor. 
The final decision on any supportive therapy or vaccination rests with the Investigator and/or 
the patient’s primary care physician. However, the decision to continue the patient on study 
therapy or vaccination schedule requires the mutual agreement of the Investigator, the Sponsor 
and the patient.
Patients are prohibited from receiving the following therapies during the Screening and 
Treatment periods (including retreatment for post-complete response relapse) of this study:

Prior treatment with gamma secretase inhibitors.

Note: the following situations are considered 1 line of therapy:

Discontinuation of one drug in a multi-drug regimen and continuation of (an) other 
drug(s).

Restarting the same regimen after a drug holiday.

Switching from IV to oral formulation of the same drug is also considered one 
regimen.

postmenopausal (a woman who has not had menses for greater than 1 year will be considered 
postmenopausal), or 3) not heterosexually active for the duration of the study. The two birth 
control methods can be either two barrier methods or a barrier method plus a hormonal method 
to prevent pregnancy. Patients should start using birth control for 30 days prior to treatment 
initiation (Cycle 1, Day 1) and throughout the study period up to 90 days after the last dose of 
investigational product.
The following are considered adequate barrier methods of contraception: diaphragm, condom 
(by the partner), copper intrauterine device, sponge, or spermicide. Appropriate hormonal 
contraceptives will include any registered and marketed contraceptive agent that contains an 
estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or 
intramuscular agents).
Patients should be informed that taking the investigational product may involve unknown risks 
to the fetus (unborn baby) if pregnancy were to occur during the study. To participate in the 
study, they must adhere to the contraception requirement (described above) for the duration of 
the study and study period up to 90 days after the last dose of investigational product. 
Reporting of Pregnancy and Lactation to the Sponsor Medical Monitor is required (see Section

7.3.3
Use in Pregnancy
If a patient inadvertently becomes pregnant while on treatment with AL101, the patient will 
immediately be removed from the study. The site will contact the patient at least monthly and 
document the patient’s status until the pregnancy has been completed or terminated. The 
outcome of the pregnancy will be reported to the Sponsor Medical Monitor (or designee) 
without delay and within 24 hours if the outcome is a serious adverse experience (e.g., death, 
abortion, congenital anomaly, or other disabling or life-threatening complication to the mother 
or newborn). The study Investigator will make every effort to obtain permission to follow the 
outcome of the pregnancy and report the condition of the fetus or newborn to the Sponsor. If a 
male patient impregnates his female partner the study personnel at the site must be informed 
immediately and the pregnancy reported to the Sponsor Medical Monitor (or designee) and 
followed as described above.

AEs occurring from the time of consent until the time of the first dose of investigational 
product which are attributed to study procedures must be reported on the designated AE eCRF. 
All AEs, including AEs attributed to study procedures, occurring from the first dose of 
investigational product until 30 days after last investigational product or until the event has 
resolved, stabilized or an outcome has been reached must be reported on the AE eCRF, 
regardless of the severity or relationship to investigational product. The Investigator should 
treat patients with AEs appropriately and observe them at suitable intervals until the events 
stabilize or resolve. AEs are identified through observation or examination of the patient, 
questioning of the patient, complaint by the patient, or by abnormal clinical laboratory values.
8.1.1
Abnormal Laboratory which Are Considered AEs
In addition, AEs may also include laboratory values that become significantly out of normal 
range. Such abnormal laboratory values or test results constitute AEs if they induce clinical 
signs or symptoms, require investigational product dose modifications or are considered 
clinically significant (e.g., cause study discontinuation or constitutes in and of itself a Serious 
Adverse Event, or require therapy, e.g., any hematologic abnormality that requires transfusion 
or cytokine treatment); and should be recorded on the AE eCRF under the signs, symptoms or 
diagnosis associated with them. In the event of an out-of-range value (abnormal, not clinically 
significant), the laboratory test should be repeated until it returns to normal or can be explained 
and the patient’s safety is not at risk.
8.1.2
Events not considered AEs
The following events/medical conditions are not considered AEs:

Disease progression (unless considered to be drug related by the Investigator).


Stable or intermittent chronic conditions (such as myopia requiring eyeglasses) that are 
present prior to study entry and do not worsen during the study

Interventions for pretreatment conditions (e.g., elective cosmetic surgery) or medical 
procedures that were planned before study enrollment.

Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction, transfusion). 
The condition that leads to the procedure is an AE if not present at baseline.

Hospitalization for elective surgery planned prior to study (situation where an untoward 
medical occurrence has not occurred).

Pregnancy will not be considered an AE, but if occurs, will be reported on pregnancy form.
8.1.3
AE Assessments
Severity of the AE will be assessed by the investigating physician in accordance with 
NCI-CTCAE v5.0 (Table 8). The Investigator should only use the term grade in Table 8 to 
describe the intensity of the AE. Only one severity definition should be used for each AE (e.g., 
"mild/moderate" is not acceptable).

The Investigator will document in his/her opinion the relationship of the AE to the 
investigational product using WHO-UMC criteria outlined in Table 9. If the relationship 
between the AE/SAE and the investigational product is determined to be “possibly related” or 
“probably related” or “definitely related” the event will be considered to be related to the 
investigational product for the purposes of expedited regulatory reporting.

8.2
SERIOUS ADVERSE EVENT (SAE)
A serious AE (SAE) is any AE occurring at any dose that results in any of the following 
outcomes:

Death

Is life-threatening

Requires inpatient hospitalization

Requires prolongation of existing hospitalization

A persistent or significant disability or incapacity or substantial disruption of the 
ability to conduct normal life functions

A congenital anomaly or birth defect

Important medical events that may not result in death, be life-threatening, or 
require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the patient and may require 
medical or surgical intervention to prevent one of the outcomes listed in this 
definition. Examples of such medical events include Grade 3 or 4 infusion 
reactions, allergic bronchospasm requiring intensive treatment in an emergency 
room or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization.
Note that hospitalization is defined as admission to treat a clinical adverse event. The following 
events would not be considered hospitalizations for SAE reporting purposes: 23-hour hold for 
observation, admission to a hospice facility or nursing home, respite care, outpatient surgery, 
social admission (e.g., a homeless patient) or admission not associated with a precipitating 
clinical adverse event (e.g., elective or pre-planned surgery, or in-patient administration of 
subsequent chemotherapy, etc.).

Note: In addition to the above criteria, AEs meeting either of the below criteria, although not 
serious per ICH definition, are reportable to the Sponsor in the same timeframe as SAEs to 
meet certain local requirements. Therefore, these events are considered serious by the Sponsor 
for collection purposes.

Is a new cancer (that is not a condition of the study).

Is associated with an overdose.
8.3
UNEXPECTED ADVERSE EVENT
An unexpected AE is any AE, the specificity or severity of which is not consistent with 
information in the clinical protocol or current Investigator’s Brochure for an unapproved 
investigational product or package insert/summary of product characteristics for an approved 
product (package inserts are available separately at the participating center).
Serious Unexpected Suspected Adverse Reaction (SUSAR) is a serious adverse reaction 
assessed as unexpected by the Sponsor and that is judged by either the reporting Investigator or 
the Sponsor to have a reasonable causal relationship to a investigational product.
8.4
ADVERSE EVENTS OF SPECIAL INTEREST
An adverse event of special interest (AESI) is one of scientific and medical interest specific to 
understanding of the Investigational Product and may require close monitoring and rapid 
communication by the investigator to the Sponsor. An AESI may be serious or non-serious. 
The rapid reporting of AESIs allows ongoing surveillance of these events in order to 
characterize and understand them in association with the use of this investigational product. 
AESI for AL101 include events that are mediated by disruption of the Notch signaling pathway 
and can be attributed to the drug’s mechanism of action with no clear alternate etiology and 
which may require more frequent monitoring and/or interventions. All AESI must be reported 
in the AESI section of the CRFs.
AESI observed with AL101 are detailed in the sections below and include hepatic function 
abnormalities, colitis, infusion reactions (including anaphylaxis), keratoacanthoma, and 
potential drug-induced liver injury (DILI). For dose modifications and toxicity management for 
the AESI, please refer to Section 6.6.
8.4.1
Hepatic Function Abnormalities (hepatotoxicity)
In study CA216001 a G5 (fatal) case of liver toxicity was reported at the 8.4 mg dose in the 
escalation phase of the study (refer to section 1.5 of the Investigator’s Brochure).
Hepatic function abnormality is defined as any increase in ALT or AST to greater than 
3 × ULN and concurrent increase in total bilirubin to be greater than 2 × ULN. Concurrent 
findings are those that derive from a single blood draw or from separate blood draws taken 
within 8 days of each other. Follow-up investigations and inquiries will be initiated promptly 
by the investigational site to determine whether the findings are reproducible and/or whether 
there is objective evidence that clearly supports causation by a disease (e.g., cholelithiasis and 
bile duct obstruction with distended gallbladder) or an agent other than the investigational

product. Guidelines for management of patients with hepatic function abnormality are outlined 
in Section 8.4.1.
Cases where a patient shows an AST or ALT ≥3ULN or total bilirubin ≥ 2×ULN may need 
to be reported as SAEs. These cases should be reported as SAEs if, after evaluation they meet 
the criteria for a Hy’s Law case or if any of the individual liver test parameters fulfill any of the 
SAE criteria. Investigational product should be interrupted immediately if any Hy’s law cases 
(section 8.4.5).
8.4.2
Colitis
In study CA216001, DLTs consisting of Grade 3 colonic ulceration/Grade 3 diarrhea were 
reported, both indicating the potential for development of colitis. Intestinal inflammation is 
thought to be an on-target effect that requires close monitoring and potential dose reductions. 
Intense abdominal pain, severe diarrhea and the presence of blood and/or mucous in the stools 
are indicative of potential colitis. Signs and symptom of colitis should prompt work up to rule 
out an infectious etiology. The gold standard for the diagnosis of colitis pathological and thus 
requires a biopsy, but in the absence of an infectious etiology, colitis should be the exclusion 
diagnosis. For management of colitis see Table 10.

Infusion Reactions including Anaphylaxis
In study CA216001 1 patient developed Grade 3 anaphylaxis, a dose limiting toxicity (DLT) at 
the 4 mg dose. In case of Grade 3 or 4 allergic reaction, stop investigational product infusion 
and disconnect infusion tubing from the patient.

In the BMS study CA216001, a Grade 2 keratoacanthoma (patient 3-37) was assessed 
as related AL101 and occurred 3-5 months after initiation of AL101.


no. 1101-002), was assessed by both the Investigator and the Sponsor as related to 
AL101 and unexpected
All patients should be closely monitored for skin changes by the investigators throughout the 
study. Any changes suspicious for malignancy should be evaluated by a dermatologist and 
treated appropriately. In addition, to remove additional risk factors for developing 
keratoacanthoma, all patients will be counseled to avoid excessive sun and UV exposure during 
the study.

8.4.5
Potential Drug-Induced Liver Injury (DILI) / Hy’s Law
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. All occurrences of potential DILIs, 
meeting the defined criteria, must be reported as SAEs (see Section 8.5 for reporting details). 
The criteria for identifying p-DILI events depend on whether the patient’s baseline liver 
biochemistry is normal or abnormal (see Figure 2).

Algorithm for p-DILI identification and mandatory SAE reporting in 
patients with - (i) normal baseline liver biochemistry, and (ii) abnormal

The key responsibilities for investigators during p-DILI assessment include: (i) Early detection, 
medical evaluation (including the exclusion of other potential causes) and rapid laboratory 
confirmation of liver-related abnormalities, and (ii) Sponsor notification of p-DILI cases via 
SAE forms. Following the gathering and assessment of relevant clinical information the 
Sponsor is responsible for: (iii) Timely evaluation and triaging of p-DILI cases, (iv) Expedited 
reporting of p-DILI cases and (v) Expanded review of p-DILI cases including a detailed 
assessment of all available clinical information, investigations and biochemical data.
Investigators are expected to monitor ongoing routine and ad hoc hepatic laboratory test results 
to rapidly determine whether a patient meets p-DILI criteria. They are expected to promptly 
notify the Sponsor/Medial Monitor of all p-DILI cases. p-DILI cases may be identified by 
abnormal liver biochemistry values, whether or not they are accompanied by liver-related signs

and/or symptoms. In both cases, expedited confirmation with repeat laboratory testing should 
occur within 3 business days using a Hepatic Laboratory Panel (ALT, AST, TB, AP). Any 
patient with an abnormal Hepatic Laboratory Panel that meets p-DILI criteria (see Figure 2) is 
a candidate for investigational product discontinuation. Any confirmed p-DILI events must be 
reported (along with a description of the clinical findings) to Sponsor as an SAE within 24 
hours of confirmation.
An extensive clinical history, examination and appropriate investigations should be obtained to 
exclude cholestatic and other apparent causes that may explain the observed abnormalities in 
liver function and/or hepatic signs and symptoms. Other apparent causes include, non-
exhaustively and by way of example only: infectious diseases (such as active hepatitis -A, -B 
and -C), congenital diseases (such as Gilbert’s syndrome), neoplastic diseases (such as 
hepatocellular carcinoma), autoimmune diseases (such as primary biliary cirrhosis) and the use 
of concomitant hepatotoxic medications (such as antibiotics, the oral contraceptive pill and 
herbal medicines). All investigations to exclude potential causes of liver function abnormalities 
or hepatic signs and/or symptoms should be guided by relevant factors such as the patient’s 
age, gender, clinical history, and signs and symptoms.
8.5
NOTIFICATION OF SERIOUS UNEXPECTED SUSPECTED ADVERSE EVENT
The Investigator is responsible for identifying, documenting, evaluating and reporting SAEs 
and SUSARs in accordance with the protocol, 21CFR312.32, 21CFR312.64, ICH-GCP 
guidelines, and all other applicable regulations.
For the time period beginning when the consent form is signed until treatment initiation (Cycle 
1, Day 1), any SAE, or follow up to an SAE, including death due to any cause other than 
progression of the cancer under study, that occurs to any patient must be reported within 24 
hours to the Sponsor if it causes the patient to be excluded from the study, or is the result of a 
protocol-specified intervention, including but not limited to washout or discontinuation of 
usual therapy, diet, or a procedure.
For the time period beginning at treatment initiation (Cycle 1, Day 1) through 30±1 days 
following cessation of investigational product (EOS visit), any SAE, or follow up to an SAE, 
including death due to any cause other than progression of the cancer under study, whether or 
not related to the Sponsor's product, must be reported within 24 hours to the Sponsor.
Additionally, any SAE, considered by an Investigator who is a qualified physician to be related 
to the investigational product that is brought to the attention of the Investigator at any time 
following consent through the end of the specified safety follow-up period (specified above), or 
at any time outside of the time period specified in the previous paragraph also must be reported 
immediately to the Sponsor.
Initial Notification
Upon identification, all SAEs will be reported by the site within 24 hours using the appropriate 
eCRF. If eCRFs are not available, SAEs should be reported by email to Clinical Safety 
within 24 hours:

These preliminary reports will be followed within 24 hours by more detailed descriptions that 
will include a completed SAE form, copies of hospital case reports (i.e., hospital progress 
notes, results of applicable diagnostic tests, laboratory results and biopsy results), autopsy 
reports, and other documents, when requested and applicable.
For regulatory purposes, the initial SAE reports should include:
a)
a suspected investigational product
b) 
an identifiable patient (e.g., study patient code number)
c) 
an AE with a seriousness and the Investigator’s assessment of the relationship to 
investigational product
d) 
an identifiable reporting source (Investigator contact details)
Once reported, the SAE form and accompanying documentation should be placed in the SAE 
section of the Investigator’s site file.
In addition, all AEs / SAEs / SUSARs will be reported to the IRB/IEC and regulatory 
authorities as required by local regulations and ICH-GCP guidelines.
Follow-up of SAEs / SUSARs
Follow-up of SAEs / SUSARs that occur during the study will continue until their satisfactory 
resolution or stabilization. In outstanding cases, it may be defined as “ongoing without further 
follow-up” by the Investigator and Sponsor’s decision.
When supplementary information is available, a follow-up SAE Report Form must be 
completed by the site (marked as “follow-up report”). The contact report information for 
follow-up SAE reporting is the same as for initial SAE reports (see above section).
Accompanying documentation, such as copies of hospital case reports, autopsy report, and 
other documents when applicable, should be sent as soon as they are available.
Once reported, the SAE form and accompanying documentation should be placed in the SAE 
section of the Investigator’s site file. If supplementary information on a SAE has to be sent, the 
SAE form has to be used marked as “follow-up report”.

Patients who have had an SAE during the treatment period must be followed clinically until all 
parameters (including laboratory) have either returned to normal or have stabilized or are 
otherwise explained.
Any newly emergent SAEs after treatment is discontinued or the patient has completed the 
study and is considered to be related to the investigational product or study participation should 
be recorded and reported immediately. The post-study period for the purpose of SAE reporting 
is up to 90 days following last visit of the study.
8.6
PREGNANCY
If a patient inadvertently becomes pregnant while on investigational product, the patient will 
immediately be removed from the study (see Section 7.3 on contraception). Full details will be 
recorded on the withdrawal page of the eCRF. Although pregnancy and lactation are not 
considered AEs, it is the responsibility of Investigators or their designees to report any 
pregnancy or lactation in a patient (spontaneously reported to them) that occurs during the 
study.
Pregnancies and lactations that occur after the ICF is signed but before treatment initiation 
(Cycle 1, Day 1) must be reported by the Investigator if they cause the patient to be excluded 
from the study or are the result of a protocol-specified intervention, including but not limited to 
washout or discontinuation of usual therapy, diet, placebo treatment or a procedure.
Pregnancies and lactations that occur from the time of treatment initiation (Cycle 1, Day 1) 
through 90 days following cessation of Sponsor’s investigational product, or 30 days following 
cessation of investigational product if the patient initiates new anticancer therapy, whichever is 
earlier, must be reported by the Investigator within the same timelines as an SAE (within 24 
hours) on a Pregnancy Monitoring Form. All reported pregnancies must be followed to the 
completion/termination of the pregnancy. If the outcome is an SAE (e.g., death, abortion, 
congenital anomaly, or other disabling or life-threatening complication to the mother or 
newborn) before end of study, the Sponsor must be notified within 24 hours using an SAE 
Report Form. If the pregnancy continues to term, the outcome (health of infant) must also be 
reported.
If a male patient impregnates his female partner, the study personnel at the site must be 
informed immediately and the pregnancy reported to the Sponsor and followed as described 
above.
All supporting source documentation including but not limited to: any hospital admission or 
discharge reports, SAE report (updated or original), clinic chart documents etc. should be kept 
in the patient record.
8.7
OVERDOSE
An overdose is defined as the accidental or intentional administration of any dose of a product 
that is considered both excessive and medically important. All occurrences of overdose must be 
reported as SAEs (see Section 8.4.5 for reporting details).

STATISTICAL ANALYSIS PLAN
9.1
GENERAL
This is a Phase 2, multicenter, single-agent, open-label study. Since this is an open-label, 
clinical study, descriptive summary statistics will be employed to analyze the data.
The standard summary statistics for continuous variables are sample size (n), mean, standard 
deviation, median, minimum and maximum. The standard summary statistics for categorical 
variables are frequencies and percentages. Time to event variables will be summarized using 
the Kaplan-Meier method. Where confidence limits are appropriate, the confidence level will 
be 95% (two-sided), unless otherwise stated. 
Individual data (including relevant derived variables) will be presented by parameter in listings. 
Results of statistical analyses, descriptive summary statistics and supportive listings will also 
be presented.
Baseline values are defined as the last valid value prior to investigational product 
administration. Baseline safety data will be presented along with subsequent safety values 
assessed during or after drug administration.
Detailed methodology for summary and statistical analyses of the data collected in this study 
will be documented in a statistical analysis plan (SAP), which will be maintained by the 
Sponsor. This document may modify the plans outlined in the protocol; however, any major 
modifications will also be reflected in a protocol amendment.
Statistical analyses will be performed using SAS® v9.4 or higher (SAS Institute, Cary NC, 
USA).

SAMPLE SIZE CONSIDERATION
The study was initiated as a Simon’s two-stage optimal design.
The study passed the futility analysis in Stage 1 of the Simon two-stage design and is currently 
continuing to enroll patients. While the data on Cohort 1 (4 mg QW) is maturing, the study will 
enroll up to a maximum of 45 patients in Cohort 1 and in parallel will be expanded with the 
addition of Cohort 2 (6 mg QW). The study will continue enrolling a total of 42 patients in 
Cohort 2, unless an unexpected safety signal emerges that in the judgement of the DMC 
requires analysis and/or poses a serious threat to the well-being of the patient. A second look is 
may be undertaken at 50% of the total information fraction (21 patients) for Cohort 2.
The updated design, a 2-look Group Sequential design with stopping for futility based on 
Pocock beta-spending function takes the first look after 21 patients and has the following 
operating characteristics:

The expansion of Cohort 1 to a maximum of 45 patients and Cohort 2 to a maximum of 42 
patients will provide at least 80% power to test the hypothesis of achieving an increase of the 
response rate from 8% to 25% using a type I error of 5%.
9.3
ANALYSIS SETS
The following analysis sets will be used in this study:

Safety analysis set: All patients who receive at least one dose of investigational product 
(even a partial dose).

Efficacy evaluable set: All patients who receive at least one dose of investigational product, 
have measurable disease at baseline per RECIST v1.1 or modified MDA criteria for bone-
exclusive disease (see Table 11), and have at least one post-baseline on-study assessment 
of tumor response.

Per-protocol (PP) analysis set: All efficacy evaluable patients who have no major protocol 
violations, as defined by the Sponsor prior to database lock.

PK analysis set includes all patients who receive investigational product and have at least 
one post baseline evaluable PK sample.
9.4
PATIENT DISPOSITION
The number and percentage of patients who are enrolled, treated, discontinued from 
investigational product, and participating in follow-up will be presented for the Safety analysis 
set and the Efficacy Evaluable set. A summary of reasons for discontinuation from treatment 
and withdrawal from the study will be provided. The number of patients included in each 
analysis set will be summarized and the reasons for excluding patients from each set will be 
listed.
9.5
DEMOGRAPHIC AND BASELINE CHARACTERISTICS
Demographic characteristics including age, gender, race, and ethnicity will be presented in the 
form of tabular summary statistics for all ITT patients. Other patient baseline characteristics 
including weight, height, body mass index (BMI), initial stage of disease, and performance 
status will be presented similarly.
9.6
EFFICACY
9.6.1
Definition of Efficacy Endpoints
The primary efficacy endpoint is the objective response rate (ORR). ORR is defined as the 
proportion of patients who have a best overall response (BOR) of CR or PR as determined 
using RECIST v1.1 or modified MDA criteria for bone-exclusive disease (see Table 11). BOR 
is defined as the best response recorded between the date of first dose of investigational 
product and the date of subsequent anti-cancer therapy. A BOR of CR or PR requires 
confirmation of the assessment at least 4 weeks later.
Other efficacy endpoints are as follows:


DOR, defined as the interval from the first documentation of CR or PR to the earlier of the 
first documentation of disease progression (per RECIST v1.1) or death from any cause.

PFS, defined as the interval from the start of investigational product to the earlier of the 
first documentation of disease progression or death from any cause

OS, defined as the time from the date of start of treatment to the date of death from any 
cause. Patients who are lost to follow-up and those not known to have died by the cut-off 
date for analysis will be censored on the date the patient was last known alive, or the data 
cut-off date, whichever is earlier.
9.6.2
Efficacy Analysis
Primary efficacy analysis will be performed on the Efficacy Evaluable set.
The ORR will be estimated based on the proportion of patients with an overall response of 
either CR or PR, taking into account any requirement for confirmation. Disease response will 
be assessed using RECIST v1.1 or modified MDA criteria for bone-exclusive disease (see 
Table 11). The estimate of the ORR will be accompanied by a 2-sided 95% exact binomial 
confidence interval (CI) derived using the Clopper-Pearson method.
DOR, PFS, and OS will be summarized descriptively. The censoring rules will be defined in 
the SAP.
Refer to the SAP for more details.
9.7
SAFETY AND TOLERABILITY ANALYSIS
The safety assessment will be based on the frequency of AEs, the incidence of clinically 
significant abnormalities of laboratory values, concomitant medication use, vital signs, pain 
assessment and physical examination data in the Safety analysis set.
Adverse events: The AE verbatim descriptions (investigator terms from the CRF) will be 
classified into standardized medical terminology using the Medical Dictionary for Regulatory 
Activities (MedDRA). AEs will be considered treatment-emergent if they start on or any time 
after the first dose of investigational product until 30 days after the last dose of investigational 
product. The incidence of treatment-emergent AEs will be summarized overall, by system 
organ class and preferred terms, and by severity grade and relationship to investigational 
product. SAEs and AEs leading to discontinuation will also be tabulated.
Other safety data: These data will be summarized by presenting the proportions of patients with 
clinically significant abnormalities or by changes from baseline values. Laboratory parameters 
will be categorized according to CTCAE v5.0 grade and shifts from baseline CTCAE grade to 
worst postbaseline grade will be summarized using shift tables. Percentages will be based on 
the number of patients with baseline and at least 1 post baseline assessment. Laboratory data 
will be listed, and abnormal results will be flagged.

DATA MANAGEMENT
10.1
DATA HANDLING AND RECORD KEEPING
Any changes to information in the study progress notes and other source documents will be 
initialed and dated on the day the change is made by a clinical site staff member authorized to 
make the change. Changes will be made by striking a single line through erroneous data and 
clearly entering the correct data (e.g., wrong data right data). If the reason for the change is not 
apparent, a brief explanation for the change will be written adjacent to the change by the 
clinician.
Patient information will be captured and managed by study sites on eCRFs by a web-based 
electronic data capture (EDC) tool developed and supported by CRO and approved by the 
Sponsor. Data should be entered into the EDC system in a timely manner as outlined within the 
eCRF Completion Guidelines. Study sites will enter data directly into an EDC system by 
completing the eCRF via a secure internet connection. Data entered into the eCRF must be 
verifiable against source documents at the study center. Data to be recorded directly on the 
eCRF will be identified and the eCRF will be considered the source document. Any changes to 
the data entered into the EDC system will be recorded in the audit trail and will be Food and 
Drug Administration (FDA) CFR 21 Part 11 compliant. Medical coding will use MedDRA for 
concomitant diseases (Medical History) and AEs and WHO Drug Dictionary for medications.
Missing or inconsistent data will be queried within the EDC system in writing to the 
Investigator for clarification. Subsequent modifications to the database will be documented.
 Data management will be performed by CRO according to their Standard Operating 
Procedures (SOPs). This will include setting up a relevant database and data transfer 
mechanisms, along with appropriate validation of data and resolution of queries. Data 
generated within this clinical study will be handled according to the relevant standard operating 
procedures (SOPs) of the data management and biostatistics departments of the CRO.
10.2
QUALITY CONTROL AND QUALITY ASSURANCE
Quality control procedures will be implemented at each stage of data handling to ensure that all 
data are reliable and have been processed correctly. Data anomalies will be communicated to 
the sites for clarification and resolution, as appropriate.
During and/or after completion of the study, quality assurance officers assigned by the Sponsor 
or the regulatory authorities may wish to perform onsite audits or inspections. The Investigator 
will be expected to cooperate with any audit or inspection and to provide assistance and 
documentation (including source data) as requested.

or withholding of treatment on the part of the Investigator.
With the declaration of consent the patient agrees that data on his/her medical history are 
recorded within the framework of the clinical study and that they are transferred to the Sponsor 
in a pseudo-anonymized manner. Patients will be informed that their race and ethnicity will be 
collected and will be used during analysis of study results.
The patient also agrees to allow the monitor/auditor/health authorities to verify the collected 
patient data against the patient's original medical records for the purpose of source data 
verification.
The ICF – personally signed and dated by the patient and the Investigator – must be kept in the 
Investigator’s study file by the Investigator(s) and documented in the eCRF and the patient’s 
medical records. The Investigator confirms to the Sponsor to obtain the written informed 
consent from any patient before participating in the study.
If new information becomes available that may be relevant to the patient’s willingness to 
continue participation in the study, a new ICF will be approved by the EC(s)/IRB(s) (and 
regulatory authorities, if required). If new safety information results in significant changes in 
the risk/benefit assessment, the consent form should be reviewed and updated if necessary. All 
patients (including those already being treated) should be informed of the new information and 
must give their written informed consent to continue in the study.
If the family doctors are informed of their patients’ participation in the clinical study, this 
should be mentioned in the consent form.
11.1.4
Data and Safety Monitoring
An independent Data Monitoring Committee (DMC) will be assigned by the Sponsor prior to 
the beginning of the study. Throughout the study, the DMC will monitor safety parameters at 
regular intervals (approximately quarterly) after at least 3 patients have been treated for at least 
2 cycles (after the first on-treatment radiographic assessment). Further details are specified in 
the DMC charter. Efficacy data will also be provided to the DMC to allow assessment of 
benefit/risk for patients. The DMC may recommend stopping the study if at any time during 
the study there are unacceptable AEs or safety concerns as described in the protocol stopping 
rules defined in the DMC charter.
For each DMC meeting, pre-specified reports will be provided. In addition, the DMC Chair 
will be provided with or have access to periodical safety and efficacy reports as specified in the 
DMC charter. The DMC Chair may share these reports with the DMC or convene additional 
meetings of the DMC at his/her discretion. The DMC Chair may request additional safety and 
efficacy data based on the review of study data.
Further details regarding data safety monitoring guidelines will be included in the DMC 
Charter, which is the governing document that supersedes this section of the protocol.

the clinical protocol and the materials necessary for conducting the clinical study.
11.4.3
Source Document
The Investigator will permit study-related monitoring, audits by or on behalf of the Sponsor, 
IRB/IEC review and regulatory inspections providing direct access to source data documents. 
Source documents are original records in which raw data are first recorded. These may be 
office/clinic/hospital records, charts, diaries, ultrasound images, and laboratory results, ECG 
printouts, pharmacy records, care records, completed scales for each study participant and/or 
worksheets provided by the Sponsor. Source documents should be kept in a secure and limited 
access area. All source documents should be accurate, clear, unambiguous, permanent and 
capable of being audited. They should be made using a permanent form of recording (ink, 
typing, printing, optical disc, etc.). They should not be obscured by correcting fluid or have 
temporary attachments (such as removable self-stick notes). Source documents that are 
computer generated and stored electronically must be printed, signed and dated by the 
Investigator.
Source data for patients registered to the study should indicate date ICF was signed, 
participation in clinical protocol number and title, treatment number, evidence that 
inclusion/exclusion criteria have been met.
11.4.4
Recording of Data on Electronic Case Report Form (eCRF)
No data will be directly entered into the eCRF without source documentation.
The study worksheets provided by the Sponsor may be used to capture all study data not 
recorded in the patient’s medical record. Alternatively, the site may create and use their own 
study worksheets. Only a patient identification number will be used to identify the patient. The 
Investigator must keep a separate log of patient names and medical record numbers (or other 
personal identifiers).
The protocol will use an Internet-Based Remote Data Entry System, primarily to collect 
clinical study data at the investigational sites. The system will be used to enter, modify, 
maintain, archive, retrieve, and transmit data. The system was configured based on 
requirements from the Sponsor. Paper source documents are to be retained to enable a 
reconstruction and evaluation of the study. No original observations will be entered directly 
into the computerized system. Source documents include the clinic or hospital patient files and 
study worksheets provided by the Sponsor. Data will be recorded in the study worksheets as 
appropriate to complete and/or clarify source data.
The design of a computerized system complies with all applicable regulatory requirements for 
record keeping and record retention in clinical studies (21 CFR Part 11 and ICH-GCP; E6)) to 
the same degree of confidence as is provided with paper systems. Clinical Investigators must 
retain either the original or a copy of all source documents sent to a Sponsor or CRO, including

query resolution correspondence. The system is designed so that changes to any record do not 
obscure the original information. The audit record clearly indicates that a change was made and 
clearly provides a means to locate and read the prior information. All changes to the data have 
an electronic audit trail, in accordance with 21 CFR 11.10(e). Electronic signatures will be used 
in conformance with 21 CFR Part 11.
11.4.5
Investigator Site File
All documents required for the conduct of the study as specified in the ICH-GCP guidelines 
will be maintained by the Investigator in an orderly manner and made available for monitoring 
and/or auditing by the Sponsor or Sponsor delegate and regulatory agencies.
11.4.6
Clinical Study Supplies
The Sponsor or its vendors will be responsible for providing study supplies and for ensuring 
that they are used, managed and accounted for properly. Accurate and timely records of the 
disposition and accountability of all investigational products must be maintained by the site and 
reviewed by the Sponsor representative monitor. The supplies and inventory record must be 
made available for inspection upon request. Upon completion or termination of the study, the 
Investigator will keep the remaining clinical supplies along with a copy of the inventory record 
and a record of the clinical supplies returned. Under no circumstances will the Investigator 
allow the investigational products to be used other than as directed by this protocol.
Upon completion or termination of the study, all study supplies will be disposed of per 
instructions from the Sponsor and/or its vendors (CRO).
Clinical study supplies include, however, not limited to: eCRF, study worksheets, laboratory 
supplies and investigational products.
11.5
DATA MANAGEMENT
Data Management services will be provided by the CRO. After the data have been entered and 
verified, various edit checks will be performed for the purpose of ensuring the accuracy, 
integrity, and validity of the database.
Queries generated from these checks will be sent to the investigational site for resolution, and 
the database will be updated to reflect query resolutions as appropriate.
For details on data management processes, please refer to the Study Data Management Plan.
11.6
STUDY COMPLETION
This study is expected to end when all required patients have been enrolled and the last patient 
has completed the follow-up visit of the study (30 days post last dose of investigational 
product) and query resolution has been completed. Collection of overall survival data will 
continue beyond the follow-up visit and will be reported separately from the clinical study

DISCLOSURE
All information provided regarding the study, as well as all information collected/documented 
during the study, will be regarded as confidential. The Investigator (or designee) agrees not to 
disclose such information in any way without prior written permission from the Sponsor.
Any publication of the results, either in part or in total (e.g., articles in journals or newspapers, 
oral presentations, abstracts) by the Investigator or their representative(s), shall require prior 
notification and review, within a reasonable time frame, by the Sponsor, and cannot be made in 
violation of the Sponsor’s confidentiality restrictions or to the detriment of the Sponsor’s 
intellectual property rights.
Sponsor will register the study and post study results regardless of outcome on a publicly 
accessible website in accordance with the applicable laws and regulations.
11.9
RECORDS
Data collected at Screening and during the study will be recorded in the patient’s source 
documents and retained at the study site for all patients who sign informed consent. Patients 
who are enrolled in the study will have their data retained in the source documents at the site 
and also have their data entered into the eCRF. To maintain confidentiality, patients will be 
identified only by screening and patient numbers.
The completed eCRFs will be transferred to the Sponsor (or designee). Copies of each source 
document will be retained by the Investigator (or designee). A compact disk containing the site 
eCRF data will be provided to the site at the completion of the study. All source documents, 
records, and reports will be retained by the clinical site in accordance with 21 CFR 312.62(c). 
The minimum retention time for study records will meet the strictest standard applicable to that 
site, as dictated by any institutional requirements or local, national, or regional laws or 
regulations. Prior to proceeding with destruction of records, the Investigator must notify the 
Sponsor in writing and receive written authorization from the Sponsor to destroy study records.
In addition, the Investigator must notify the Sponsor of any changes in the archival 
arrangements including but not limited to archival at an offsite facility or transfer of ownership 
if the Investigator leaves the site.
All primary data, or copies thereof (e.g., laboratory records, eCRFs, data sheets, 
correspondence, photographs, and computer records), which are a result of the original 
observations and activities of the study and are necessary for the reconstruction and evaluation 
of any study report, will be retained in the clinical site archives.

APPENDIX C
SUMMARY OF RESPONSE EVALUATION CRITERIA IN SOLID 
TUMORS (RECIST) V1.1
Disease response will be evaluated using the Response Evaluation Criteria in Solid Tumors 
(RECIST) criteria (version 1.1). The following appendix summarizes the process for selecting 
baseline measurable lesions and deriving the appropriate response at subsequent imaging time 
points. For specific details related to the response criteria please refer to the published RECIST 
criteria (version 1.1) (Eisenhauer, 2009).
Establishing a Baseline Overall Tumor Burden:
To assess objective response or future progression, it is necessary to estimate the overall tumor 
burden at baseline and use this as a comparator for subsequent measurements. The disease 
burden at baseline will be categorized into target and non-target lesions.
Target Lesions:

Identify a maximum of 5 target lesions (up to 2 target lesions per organ).

Target lesions must be measurable; where measurable is defined:

10 mm in the longest diameter by CT (preferred) or MRI scan (or no less than 
double the slice thickness) for non-nodal lesions and ≥ 15 mm in short axis for 
nodal lesions

10 mm caliper measurement by clinical exam

20 mm by chest X-ray
NOTE: Regardless of the imaging modality blastic bone lesions will not be 
selected as target lesions. Lytic or mixed lytic-blastic lesions with a measurable 
soft tissue component ≥ 10 mm can be selected as target lesions.
NOTE: Lesions having undergone prior intervention (e.g., previous irradiation) 
will not be selected as target lesions unless there has been a demonstration of 
progress in the lesion.

Target lesions should be selected on the basis of their size (lesions with the longest 
diameter), be representative of all involved organs, but in addition should be those that 
lend themselves to reproducible repeated measurements.

Calculate the sum of the diameters (SOD) of all target lesions.

For non-nodal lesions: the longest diameter should be included in the sum of diameters

For nodal lesions: the short axis measurement (i.e., widest dimension perpendicular to 
the long axis) should be included in the sum of diameters
Non-Target Lesions:

All remaining lesions (including pathological lymph nodes) are followed as non-target 
lesions. There is no limit to the number of non-target lesions that can be recorded at 
baseline. Baseline measurements are not required for non-target lesions.

Evaluation of Tumor Burden at Subsequent Assessments:
Please refer to the SoA (Table 1) for the timing of subsequent imaging assessments.
Target Lesions:
Target lesions are measured at every subsequent assessment and an overall SOD is calculated. 
Target lesions are assessed as Complete Response (CR), Partial Response (PR), Stable Disease 
(SD), Progressive Disease (PD), or Not All Evaluated (NAE) at every time point based on the 
calculated SOD.
Target Assessment
Evaluation Definition
Complete Response (CR)
CR is declared if ALL of the following are true for target lesions:

The disappearance of all non-nodal target lesions

Any pathological lymph nodes must have a reduction in short 
axis to <10 mm.
Partial Response (PR)
PR is declared if there is a decrease of at least 30% in the SOD of 
target lesions compared to the baseline SOD of target lesions.
Progressive Disease (PD)
PD is declared if ANY of the following are true for target lesions:

SOD of all target lesions increases at least 20% compared to the 
smallest SOD recorded from any prior assessment
NOTE: In addition to the relative increase at least 20%, the sum 
must also demonstrate an absolute increase of at least 5 mm.
OR

The appearance of one or more new lesions.
Stable Disease (SD)
SD is declared if target lesion assessment does not meet criteria for 
PR, PD, or CR.
Non-Target Lesions:
While some non-target lesions may actually be measurable, they need not be measured and 
instead should be assessed qualitatively at subsequent assessments. Non-target lesions are 
assessed as CR, PD, non-CR/non-PD (NCNP), or NAE at every time point.
Non-Target Assessment
Evaluation Definition
Complete Response (CR)
CR is declared if ALL of the following are true for non-target lesions:

Disappearance of all non-target lesions and normalization of 
tumor marker level.

All lymph nodes must be non-pathological in size (<10 mm 
short axis).
Non-CR/Non-PD (NCNP)
NCNP is declared when persistence of one or more non-target 
lesion(s) and/or the maintenance of tumor marker level above the 
normal limits is observed.
Progressive Disease (PD)
PD is declared if ANY of the following are true for non-target lesions:

Unequivocal Progression of existing non-target lesions.
NOTE: Unequivocal Progression of non-target disease is 
defined as an overall level of substantial worsening in non-

Confidential
target disease such that, even in presence of SD or PR 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 lesion(s) is usually not sufficient to 
quality for unequivocal progression. The designation of overall 
progression solely on the basis of change in non-target disease 
in the face of SD or PR of target disease should therefore be 
extremely rare.
OR

The appearance of one or more new lesions.
New Lesions:
The determination of new lesions should be unequivocal and not be attributable to differences in 
the scanning technique, change in modality, or findings thought to represent something other 
than tumor. This is particularly important when the patient’s target lesions show PR or CR.
A lesion identified at a subsequent time point in an anatomical location that was not scanned at 
baseline is considered a new lesion and will indicate disease progression. This underscores the 
importance of scanning all anatomical locations that are suspected to contribute to disease 
burden at baseline. 
Overall Time Point Response Assignment at Subsequent Assessments:
Once the Target-Lesion, Non-Target Lesion, and New Lesion Assessments have been completed 
for a subsequent imaging assessment, an Overall Time Point Response may be assigned.

Section 4.1
Inclusion no. 9:  WOCBP must agree to follow instructions for method(s) of contraception for 
the duration of the treatment with AL101 plus 90 days post-treatment completion.
Inclusion no. 10: Men who are sexually active with WOCBP must agree to follow instructions 
for method(s) of contraception for the duration of treatment with AL101 plus 90 days (duration 
of sperm turnover) post-treatment completion.
Section 7.3:
AL101 may have adverse effects on a fetus in utero. Furthermore, it is not known if AL101 has 
transient AEs on the composition of sperm. Non-pregnant, non-breast-feeding women may be 
enrolled if they are willing to use 2 methods of birth control or are considered highly unlikely to 
conceive. Highly unlikely to conceive is defined as 1) surgically sterilized, or 2) postmenopausal 
(a woman who has not had menses for greater than 1 year will be considered postmenopausal), 
or 3) not heterosexually active for the duration of the study. The two birth control methods can 
be either two barrier methods or a barrier method plus a hormonal method to prevent pregnancy. 
Patients should start using birth control for 30 days prior to treatment initiation (Cycle 1, Day 1) 
and throughout the study period up to 90 days after the last dose of investigational product.
The following are considered adequate barrier methods of contraception: diaphragm, condom (by 
the partner), copper intrauterine device, sponge, or spermicide. Appropriate hormonal 
contraceptives will include any registered and marketed contraceptive agent that contains an 
estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or 
intramuscular agents).
Patients should be informed that taking the investigational product may involve unknown risks to 
the fetus (unborn baby) if pregnancy were to occur during the study. To participate in the study, 
they must adhere to the contraception requirement (described above) for the duration of the study 
and study period up to 90 days after the last dose of investigational product. Reporting of 
Pregnancy and Lactation to the Sponsor Medical Monitor is required (see Section 8.6). If there is 
any question that a patient will not reliably comply with the requirements for contraception, that 
patient should not enter the study.

2) postmenopausal (a woman who has not had menses for greater than 1 year will be considered 
postmenopausal), or 3) not heterosexually active for the duration of the study. Patients should 
start using birth control for 30 days prior to treatment initiation (Cycle 1, Day 1) and throughout 
the study period up to 90 days after the last dose of investigational product.
The following are considered highly effective method of contraception:
For women of childbearing potential, including female study participants and partners of male 
participants, effective contraception is defined as follows:

combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation:
-
oral
-
intravaginal
-
transdermal

progestogen-only hormonal contraception associated with inhibition of ovulation:
-
oral
-
injectable
-
implantable


intrauterine device (IUD)

intrauterine hormone-releasing system (IUS)

bilateral tubal occlusion

vasectomized partner with documentation of the success of the vasectomy

complete abstinence from heterosexual intercourse (periodic abstinence is not a safe 
method)
Male patients with partners who are women of childbearing potential should use a combination 
of the above specified methods for the women along with a male condom during the study and 
for 90 days after the last dose of investigational product, unless permanently sterile by bilateral 
orchidectomy.
Patients should be informed that taking the investigational product may involve unknown risks to 
the fetus (unborn baby) if pregnancy were to occur during the study. To participate in the study, 
they must adhere to the contraception requirement (described above) for the duration of the study 
and study period up to 90 days after the last dose of investigational product. Reporting of 
Pregnancy and Lactation to the Sponsor Medical Monitor is required (see Section 8.6). If there is 
any question that a patient will not reliably comply with the requirements for contraception, that 
patient should not enter the study.
France
ANSM require that contraception will be used for 120 days (4 months) post last dose of AL101, 
therefore the following sections were modified and are to be followed in France:
Section 4.1
Inclusion no. 9: WOCBP must agree to follow instructions for method(s) of contraception for the 
duration of the treatment with AL101 and for 120 days (4 months) after the last dose of AL101.
Inclusion no. 10: Men who are sexually active with WOCBP must agree to follow instructions 
for method(s) of contraception for the duration of treatment with AL101 and for 120 days 
(4 months) after last dose of AL101
Section 7.3:
AL101 may have adverse effects on a fetus in utero. Furthermore, it is not known if AL101 has 
transient AEs on the composition of sperm. Non-pregnant, non-breast-feeding women may be 
enrolled if they are willing to use 2 methods of birth control or are considered highly unlikely to 
conceive. Highly unlikely to conceive is defined as 1) surgically sterilized, or 2) postmenopausal 
(a woman who  has not had menses for greater than 1 year will be considered postmenopausal), 
or 3) not heterosexually active for the duration of the study. The two birth control methods can 
be either two barrier methods or a barrier method plus a hormonal method to prevent pregnancy. 
Patients should start using birth control for 30 days prior to treatment initiation (Cycle 1, Day 1) 
and throughout the study period up to 120 days (4 months) after the last dose of investigational 
product.

The following are considered adequate barrier methods of contraception: diaphragm, condom (by 
the partner), copper intrauterine device, sponge, or spermicide. Appropriate hormonal 
contraceptives will include any registered and marketed contraceptive agent that contains an 
estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or 
intramuscular agents).
Patients should be informed that taking the investigational product may involve unknown risks to 
the fetus (unborn baby) if pregnancy were to occur during the study. To participate in the study,

APPENDIX F
PROTOCOL AMENDMENT HISTORY AND SUMMARY OF 
CHANGES
The Protocol Amendment Summary of Changes Table for the current amendment is located 
directly above the synopsis. Histories for previous global amendments appear below.
The following changes were made to the protocol in reverse chronological order, including country-
specific amendments. Order of changes is presented by order of appearance in the protocol.
AMENDMENT 2 (V3.0); 20 DECEMBER 2019
Protocol Version

Rev.
Summary of Change
Rationale for Change
Synopsis and Section 2 Objectives and 
Endpoints
Change primary endpoint to be 
Investigator assessed.
Add objective/endpoint for patient 
reported outcome measure (EORTC 
QLQ-C30) to Cohort 2
Investigator-assessed is 
appropriate for this study phase.
Radiological images are being 
collected for central review 
should this become required.
To evaluate the effect of AL101 
6 mg QW on patients’ quality of 
life.
Synopsis and Section 3 Study Design
Add sequential Cohort 2 (6 mg once 
weekly; QW) and clarify enrollment 
process.
Study expansion and higher 
dose (while adhering to set 
safety toxicity management 
guidelines), may improve 
efficacy and maintain patient’s 
safety.
The current results in patients 
with ACC suggest that a higher 
dose of AL101 may be well 
tolerated in this patient 
population particularly with the 
use of steroids and other toxicity 
management guidelines. Prior 
studies suggest that the increase 
to 6 mg will result in a higher 
exposure and more substantial 
inhibition of the Notch pathway 
and this may result in improved 
efficacy in this difficult to treat 
patient population.
Protocol V3.0, 
Amendment 2, 
Global
5.0
Clarify information to be collected for 
medical history.

progression prior and while 
being treated with AL101.
Clarify that enrollment of patients with 
bone exclusive disease will be eligible 
after discussion and approval by the  
Sponsor’s Medical Monitor (patient 
must have evaluable and measurable 
lesions)
Patients with bone disease may 
have lesions that are very 
difficult to measure. Discussions 
with the Sponsor will clarify 
whether the lesions are 
measurable and whether the 
patients qualify for the study.
Clarify that patients with radiological 
progression may continue on 
investigational product provided they 
derive clinical benefits, they consent, 
and this is agreed upon the Investigator 
and Sponsor’s Medical Monitor. 
To allow patients with 
radiological progression who 
derive clinical benefit to 
continue treatment with 
investigational product
Clarify that on-treatment radiological 
scans will be collected and held for 
future retrospective analysis by an 
independent central review.
Retrospective central review is 
appropriate for this study phase.
Synopsis, Section 4.1 Inclusion criteria 
and Section 7.4
Align with study design, and country-
specific requirements; sections refer to 
Appendix E for country-specific 
requirements.
Appendix E (country specific 
requirements) was added to 
address changes to contraceptive 
language requests from MHRA 
and ANSM regulatory agencies.
Synopsis and Section 6.1 
Investigational Product Administration
Add 6 mg QW regimen.
Clarify premedication use for 
medications containing Cremophor.
Align with study design regarding 
continuation of investigational product.

precaution to avoid 
hypersensitivity reaction.
Protocol consistency.
Synopsis and Section 9 Statistical 
Analysis
Update sample size consideration.
Revise PK analysis set definition.
Sample size updated to reflect 
changes in study design.
PK is collected for all patients, 
therefore analysis set definition 
was updated.

4 INTRODUCTION  
The purpose of this statistical analysis plan (SAP) is to provide comprehensive and 
detailed descriptions of the methods and presentation of data analyses proposed for Ayala 
Pharmaceuticals, Inc. Protocol AL-ACC-101 (A Phase 2, Open-Label, Single-Arm,  
Multi-Center Study of AL101 in Patients with Adenoid Cystic Carcinoma [ACC] Bearing 
Activating Notch Mutations). Descriptions of planned analyses are provided to avoid post 
hoc decisions that may affect the interpretation of the statistical analysis. The statistical 
methods applied in the design and planned analyses of this study are consistent with the 
International Council for Harmonisation (ICH) guideline Statistical Principles for 
Clinical Trials (E9) (1998).   
This SAP will be finalized prior to database lock to provide full details, including 
templates for tables, listings, and figures, to be presented in the clinical study report 
(CSR). Where there are differences between the protocol and the SAP, the SAP will 
supersede the protocol. Any changes between the statistical methods provided in the 
clinical study protocol and this SAP will be explained herein; any changes or deviations 
from this SAP relative to the final analysis will be fully documented in the CSR. Minor 
changes or deviations from the templates for tables, figures, and listings need not be 
documented in the CSR.  
The SAP has been updated between the dry-run and database lock to align with what has 
now been agreed as being required with regards to the CSR. Several outputs which were 
not explicitly mentioned in the protocol but were added prior to finalization of version 
1.0 of the SAP have been removed since these are no longer required for the CSR. An 
additional analysis population based on central review of the scans has been added for the 
analysis based on the central review data. No changes were made with regards to 
analyses planned in the protocol.

6 INVESTIGATIONAL PLAN  
6.1  
Overall Study Design  
This is a Phase 2, non-comparative, open-label, multicenter study of AL101 in patients 
with recurrent or metastatic ACC who harbor NOTCH 1,2,3,4 activating mutations.  
The study includes 2 cohorts, ran in a sequential fashion:  
• 
Cohort 1 – AL101 4 mg once weekly (QW) intravenously (IV)  
• 
Cohort 2 – AL101 6 mg QW IV  
Cohort 1 will continue to enroll to reach up to a maximum of 45 patients. Cohort 2 will 
open for enrollment up to a maximum of 42 patients. Prior to entering the study, to 
determine eligibility, potential candidates will undergo pre-screening assessment and 
confirmation for the presence of activating Notch mutations. Available mutation status 
from prior tests with any commercially available or locally developed NGS assay are 
acceptable. In Europe any commercially available CE marked device shall be used.

If historical genotyping results are not available, testing will need to be conducted during 
prescreening using a laboratory developed or commercially available NGS assay to 
identify and confirm an activating Notch mutation. Any newly characterized mutation 
(such as tandem duplication, variant allele frequency, variants of unknown significance, 
etc.), will be evaluated with the Sponsor on a case-by-case basis. Pre-screening 
studyspecific assessments may be done while potential candidates are on other therapy 
provided that a separate pre-screening informed consent form is signed.  
Patients with activating Notch mutations will then undergo screening assessments to 
determine study eligibility over a 28-day Screening period. Enrollment of patients with 
bone exclusive disease should be discussed and approved by the Sponsor’s Medical 
Monitor before enrollment. For all patients, prior treatments and responses to such 
treatments, including radiological images and reports, within a year of study entry will 
be collected as part of the medical history; for patients who are currently enrolled, this 
information will be collected retrospectively.  
Starting on Cycle 1, Day 1, eligible patients will receive AL101, either 4 mg QW IV in 
Cohort 1or 6 mg QW IV in Cohort 2, on Days 1, 8, 15, and 22 of each 28-day cycle until 
disease progression, unacceptable toxicity, or consent withdrawal. For patients with 
radiological progression, investigational product may be continued as long as the patient 
is having clinical benefit, is agreed to by the patient and physician and approved by the 
Sponsor’s Medical Monitor.  
Paired tumor biopsies will be collected at screening (fresh or archival5 within 3 years) 
and on treatment at Cycle 4 Day 1 ±28 days provided medically safe and not 
contraindicated. Samples will be sent to a central vendor for NGS analysis. Tumor 
Formalin-fixed paraffin embedded (FFPE) slides will be evaluated by IHC for NICD1 
stain. On the day of the on-treatment biopsy, blood will also be drawn for PK and 
biomarker assessments.  
During the Treatment period, patients will undergo radiographic assessments every 8 
weeks (±3 days) for review by the Investigator. Scans will be collected and held for 
possible future retrospective evaluation by independent central review (ICR). Other 
assessments will be done as specified in Schedule of Activities (SoA; Table 1), including 
safety and exploratory biomarkers.  
A repeat of tumor imaging will be required for the purposes of confirmation of response 
(i.e., partial response, and/or complete response). The confirmation scan should be no 
earlier than 4 weeks following the first indication of response.  
All patients will undergo end of study (EOS) visit 30 days post last treatment and be 
contacted by phone every 3 months to determine survival status. In patients who 
discontinued investigational product due to toxicity, radiographic imaging will be done

Notes to Schedule of Activities:  
All assessments to be performed pre-infusion unless stated otherwise.  
Visit window will be ±2 days during treatment period, except for imaging ±3 days; EOS and Long-term follow-up will be ±7 days.  
a. Pre-screening assessments may be done while potential candidates are on other therapy provided that a separate pre-screening informed consent form is signed.  
b. For determining eligibility potential candidates will undergo a pre-screening assessment to confirm the presence of activating Notch mutations. Available genotyping results 
from a laboratory developed or commercially available NGS assay are acceptable. If historical genotyping results are not available, patient must sign prescreening ICF, and 
testing will need to be conducted during pre-screening using a laboratory developed or commercially available NGS assay. Available NGS test results will be shared in the 
Preidentification form and response confirming activating Notch mutation is required before entering screening. Any newly characterized mutation (such as tandem duplication, 
variant allele frequency, variants of unknown significance, etc.), will be evaluated with the Sponsor on a case-by-case basis.  
c. Paired tumor biopsies (a resection, or core needle or punch biopsy with 20 gauge or larger and at least 2 passes) will be collected both at screening (fresh or archival within 3 
years), and at Cycle 4 Day 1 ±28 days or earlier if the patient progressed (fresh sample, provided medically safe and not contraindicated). If an archival tumor block or 25 
unstained slides are not available, the patient will be required to have a fresh tumor sample obtained at screening. Attempts should be made to biopsy lesions which are not 
considered to be “target lesions” per RECIST 1.1. criteria.  
d. Full physical examination at baseline; targeted physical examination at other time points.  
e. Complete blood count (CBC) includes hemoglobin, hematocrit, platelet count, WBC count, and absolute differential count.  
f. Chemistry includes glucose, blood urea nitrogen (BUN), creatinine, total bilirubin (a direct bilirubin should be obtained if the total bilirubin level is >1.5 times ULN), albumin, 
AST (SGOT), ALT (SGPT), alkaline phosphatase (ALP), lactate dehydrogenase, electrolytes (sodium, potassium, chloride, calcium, magnesium, and phosphorus. Creatinine 
clearance (CrCl) will be conducted at screening only; Calculation of CrCl will be based on acceptable institution standard). g. Screening laboratory may be used if conducted 
within 3-7 days of CID1.  
h. Chemistry will be conducted every week for the first 3 cycles and then every 2 weeks, with the exception of liver function tests (AST/ALT/ALP/bilirubin) which will be done 
weekly until week 32, and then every 2 weeks thereafter.  
i. Coagulation factors will be done on Day 1 of every other cycle (e.g., C3D1, C5D1…).

j. Urinalysis (specific gravity, pH, glucose, protein, ketones, and blood) performed at Screening and as clinically indicated.  
k. In the event of possible abnormal ECG findings, per the discretion of the investigator, additional ECG reads could be added at follow-up visits. The ECG evaluation will be 
performed centrally. Clinically significant ECG abnormalities will be recorded on the eCRF. Triplicate ECGs, at least 3 minutes apart, will be performed if QTcF is > 500 msec 
or if the Investigator identifies an ECG finding (for example QT interval prolonged or cardiac arrythmia) that is an adverse event and related to investigational product. l. Pre-
menopausal female patients of childbearing potential only. Urine or serum pregnancy tests are acceptable.  
m. CT or MRI with contrast, of the neck, chest, abdomen, and pelvis are acceptable (PET/CT is not allowed for study assessments, unless CT is done with IV contrast). Images 
will be repeated every 8 weeks (±3 days) during treatment period until disease progression. During the Long-term Follow-up visit, only in patients who discontinued 
investigational product due to toxicity, radiographic imaging will be done every 3 months until disease progression or until patient initiates another anti-cancer therapy. The same 
radiographic technique of each region must be used consistently throughout the study. Refer to Imaging Manual. A repeat of tumor imaging will be required for the purposes of 
confirmation of response (i.e., partial response, and/or complete response). The confirmation scan should be no earlier than 4 weeks following the first indication of response. n. 
Quality of life questionnaire will be administered every 4 weeks before investigational product administration or receipt of radiological imaging results

Treatment  
6.3.1  
Treatment Administered  
AL101 will be administered IV at the dose of 4 mg every 7 days (±2 day; QW) in Cohort 
1 and at the dose of 6 mg every 7 days (±2 day; QW) in Cohort 2 over 28-day cycles until 
disease progression, unacceptable toxicity, or consent withdrawal. For patients with 
radiological progression, investigational product can be continued as long as the patient is 
having clinical benefit, is agreed to by the patient and physician and approved by the 
Sponsor’s Medical Monitor.   
AL101 will be administered using an IV infusion pump over 60 minutes; time windows 
of -5 minutes to +10 minutes are permitted.  
AL101 injection has been developed as a single-use sterile solution (1.2 mg/mL) for IV 
administration in clinical studies; each vial contains 5 mL (equivalent of 6 mg per vial). It 
is formulated as a sterile concentrate containing Cremophor® and ethanol and will be 
diluted with 0.9% Sodium Chloride Injection, USP (normal saline) or 5% Dextrose 
Injection, USP (D5W) to concentrations between 0.01 mg/mL and 0.06 mg/mL. In order 
to reduce the risk of infusion reactions caused by Cremophor, use premedication per 
institution guidelines such as H1- and H2-blockers (diphenhydramine and ranitidine or 
equivalents) or dexamethasone will be given.  
If an infusion is extended, interrupted or discontinued prior to completion, the duration 
and the reason for any dose extension, interruption or discontinuation will be recorded in 
the electronic case report form (eCRF).  
6.3.2  
Method of Assigning Subjects to Treatment Groups  
This is an open-label design, with all patients assigned sequentially to 1 of 2 cohorts and 
receive AL101 monotherapy. Cohort 1 enrolled up to a maximum of 45 patients and 
cohort 2 enrolled up to a maximum of 42 patients.

with bone-exclusive disease (Protocol Appendix C, Table 11).  
BOR is defined as the best response recorded between the date of first infusion of 
investigational product and the date of subsequent anti-cancer therapy. A BOR of CR or 
PR requires confirmation of the assessment at least 4 weeks later. A BOR of SD requires 
the assessment to be recorded no less than 4 weeks after the start of study medication.  
RECIST 1.1 (Eisenhauer 2009) will be used to determine response at each post-baseline 
time point. Assessment of target lesions, non-target lesions, new lesions, and overall 
response will be assigned as described in Table 3, Table 4 and Table 5. Table 6 describes 
the derivation of best overall response from overall response assessments at each visit.  
  
Table 3  
RECIST 1.1 Evaluation of Target Lesions:  
Response  Definition  
CR  
Disappearance of all target lesions. Any pathological lymph nodes must 
have reduction in short axis to < 10 mm.  
PR  
At least a 30% decrease in the sum of the diameters of target lesions, 
taking as reference the baseline sum diameters.  
PD  
At least a 20% increase in the sum of the diameters, taking as reference 
the smallest sum on study (this includes the baseline sum if that is the 
smallest on study). In addition to the relative increase of 20%, the sum 
must also demonstrate an absolute increase of at least 5 mm. The 
appearance of one or more new lesions is also considered progression.   
SD  
Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD, taking as reference the smallest sum diameters on study.  
  
Table 4  
RECIST 1.1 Evaluation of Non-target Lesions:  
Response  Definition  
CR  
Disappearance of all non-target lesions and normalization of tumor marker 
level. All lymph nodes must be non-pathological in size (< 10 mm short 
axis).  
SD   
Persistence of one or more non-target lesion(s) or/and maintenance of 
tumor marker level above the normal limits.  
PD  
Appearance of one or more new lesions and/or unequivocal progression of 
existing non-target lesions.

* Item range is the difference between the possible maximum and the minimum response to individual 
items; most items take values from 1 to 4, giving range = 3.  
† (revised) scales are those that have been changed since version 1.0, and their short names are indicated in 
this manual by a suffix “2” – for example, PF2.  
For all scales, the RawScore (RS) is the mean of the component items:  
𝑅𝑆 = (𝐼1 + 𝐼2 + ⋯ + 𝐼𝑛)/𝑛  
A linear transformation to 0-100 is then applied to obtain the score S:  
Functional scales:  
(𝑅𝑆 − 1) 
𝑆 = {1 −

Range is the difference between the maximum possible value of RS and the minimum 
possible value. The QLQ-C30 has been designed so that all items in any scale take the same 
range of values. Therefore, the range of RS equals the range of the item values. Most items 
are scored 1 to 4, giving range = 3. The exceptions are the items contributing to the global 
health status / QoL, which are 7-point questions with range = 6.  
The scales will be computed only if at least half of the required responses are non-missing. 
For example, role functioning (RF) and cognitive functioning (CF) each contain 2 items, 
and so these scales can be estimated whenever one of their constituent items is present; 
physical functioning contains 5 items, and so at least 3 need to have been completed. None 
of the single-item measures will be calculated if the question has not been answered.

Description of Safety Variables  
6.4.2.1  
Adverse Events  
Adverse events (AEs) will be assessed and recorded at all study visits throughout the 
study from informed consent signing through EOS visit (30 days following cessation of 
investigational product). AEs are described in detail in Section 8.1 of the protocol.   
Treatment-emergent adverse events (TEAEs) are defined as those AEs with onset during 
or after the first infusion of investigational product until 30 days after the last infusion of 
investigational product or existing events that worsened after the first infusion during the 
study until 30 days after the last infusion of investigational product.   
Events reported with a partial onset date (eg, month and year are reported but the day is 
missing) will be considered treatment-emergent if it cannot be confirmed that the event 
onset was prior to the first dose of investigational product based on the available date 
entries.  
Verbatim terms on case report forms will be mapped to preferred terms and system organ 
classes using the Medical Dictionary for Regulatory Activities (MedDRA, version 23.0).   
Severity of the TEAEs will be graded based on NCI Common Terminology Criteria for

Adverse events of special interest (AESI) include hepatic function abnormalities 
(hepatotoxicity), colitis, infusion reactions (including anaphylaxis), Keratoacanthoma and 
potential drug-induced liver injury (DILI).  
6.4.2.2  
Medical History and Concomitant Medications  
Any clinically significant diseases including any co-morbid conditions requiring active 
treatment as well as significant surgeries will be documented in the medical history 
section of the eCRF. This includes prior medical history and treatment regimens for ACC. 
Verbatim terms on case report forms will be mapped to preferred terms and system organ 
classes using the Medical Dictionary for Regulatory Activities (MedDRA, version 23.0) 
and will be summarized by SOC and PT.  
  
  
Abnormal physical examination finding and/or the diagnosis of concomitant disease 
resulting from assessments at Screening will also be documented in the medical history 
section. Information on all interventions (systemic therapy, surgery, radiation treatment) 
related to the subject’s cancer will also be collected. Radiology and photography reports 
from imaging conducted as routine care will be collected if available from the last 3 
years.   
Concomitant medication is defined as any prescription or over-the-counter preparation, 
including vitamins and supplements. Use of concomitant medication from 28 days before 
Day 1 of Cycle 1 through 30 days after the last dose of investigational product will be 
recorded. Concomitant medications will be coded according to the WHO Drug dictionary 
and will be summarized according to the coded terms.  
6.4.2.3  
Eastern Cooperative Oncology Group Performance Status  
The Eastern Cooperative Oncology Group (ECOG) Performance Status will be collected 
at all study visits and be used to assess the subjects’ performance status.   
6.4.2.4

Data Quality Assurance  
Report summaries will be generated using validated Base SAS  software, version 9.4 or 
higher, on a PC or server-based platform. Additional validated software may be used to 
generate analyses, as needed.   
All SAS programs that create outputs or supporting analysis datasets will be validated by 
a second statistical programmer or biostatistician. At a minimum, validation of programs 
will consist of a review of the program log, review of output or dataset format and 
structure, and independent confirmatory programming to verify output results or dataset 
content. Additionally, all outputs will undergo a review by a senior level team member 
before finalization.  
The content of the source data will be reviewed on an ongoing basis by project statistical 
programmers and statisticians. Data will be checked for missing values, invalid records, 
and extreme outliers through defensive programming applications, analysis-based edit 
checks, and other programmatic testing procedures. All findings will be forwarded to the 
project data manager for appropriate action and resolution.

7 STATISTICAL METHODS  
7.1  
General Methodology  
Data will be analyzed by Precision for Medicine biostatistics personnel. Statistical 
analyses will be reported with tables, figures, and listings, presented in rich text format, 
and using recommended ICH numbering. Output specifications for all tables, figures, and 
listings will be in conformance with guidelines specified by the ICH in Appendix 7 of the 
Electronic Common Technical Document Specification (Apr 2003).   
7.1.1  
Reporting Conventions  
Tables and figures will be summarized by dose cohort. All tables (including efficacy) will 
also include a column for all subjects combined. In general, all collected data and any 
derived data will be presented in subject data listings, for all enrolled subjects. Listings 
will be ordered by dose cohort, site (part of subject number), subject number and 
assessment or event date.   
In general, continuous variables will be summarized to indicate the study population 
sample size (N), number of subjects with available data (n), mean, SD, median, 25th (Q1) 
and 75th (Q3) quartiles, minimum, and maximum values, unless otherwise specified. 
Categorical variables will be summarized by the population size (N), number of subjects 
with available data (n), number of subjects in each category, and the percentage of 
subjects in each category. Unless otherwise noted, the denominator to determine the 
percentage of subjects in each category will be based on the number of subjects with 
available data. Select ordinal data may be summarized using both descriptive statistics 
and counts and percentages of subjects in each category, as appropriate.  
Non-zero percentages will be rounded to one decimal place. Rounding conventions for 
presentation of summary statistics will be based on the precision of the variable of 
summarization, as it is collected in its rawest form (i.e., on the electronic case report form 
[eCRF] or as provided within an external file) and are outlined as follows:  
• 
The mean and median will be rounded to one more decimal place than the 
precision of the variable of summarization;  
• 
Measures of variability (e.g., SD, SE) will be rounded to two more decimal places 
than the precision of the variable of summarization; and  
• 
Minimum and maximum values will be presented using the same precision as the 
variable of summarization.

Time to event variables will be summarized using the Kaplan-Meier method. Where 
confidence limits are appropriate, the confidence level will be 95% (two-sided), unless 
otherwise stated.   
7.1.2  
Summarization by Visit  
Data summarized by study visit will be based on the nominal, scheduled visit label as 
reported on the eCRF.   
Data collected at unscheduled visits will not be included in by-visit summaries, but will 
be considered when endpoint derivations potentially include multiple visits (e.g., 
determination of baseline value, determination of worst post-baseline value, etc.). All data 
will be included in subject listings.  
7.1.3  
Baseline Value  
For analyses listed in this SAP, the baseline value is defined as the last measurement 
reported prior to the first infusion of investigational product, unless otherwise noted. 
Assessments done at the C1D1 visit are performed pre-infusion unless otherwise noted. 
In cases where there is more than one pre-infusion value, the most recent pre-infusion 
value will be determined to be the baseline.   
7.1.4  
Data Handling Rules  
Unless otherwise noted, values reported as greater than or less than some quantifiable 
limit (eg, “< 1.0”) will be summarized with the sign suppressed in summary tables and 
figures, using the numeric value reported. Data will display on subject listings to include 
the sign.  
7.1.5  
Standard Calculations  
Where appropriate, the calculated study day of each assessment or event will be presented 
with the assessment or event date on subject data listings, where study day will be 
determined as:  
• 
The assessment/event date minus the date of first infusion, if the assessment/event 
date is prior to the date of first infusion; and  
• 
The assessment/event date minus the date of first infusion, plus one, if the 
assessment/event date is on or after the date of first infusion.  
Other variables requiring calculations will be derived using the following formulas:  
• 
Days: A duration between two dates expressed in days will be calculated as 
follows:

7.2  
Analysis Populations  
The analysis sets are defined as follows:   
  
• 
Safety analysis set: Includes all subjects who receive at least one infusion of 
investigational product, including partial infusions.   
• 
Efficacy Evaluable analysis set: Includes all subjects who receive at least one 
complete infusion of investigational product, have measurable disease at baseline 
per RECIST v1.1 or modified MDA criteria for bone-exclusive disease and have 
at least one post-baseline on-study assessment of tumor response (based on local, 
Investigator read data). This population will be used for the analysis of efficacy  
data based on local read data and efficacy data which is not dependent on the 
reader (i.e. overall survival). Baseline summaries will also use this population.  
• 
Efficacy Evaluable analysis set (Central): Includes all subjects who receive at 
least one complete infusion of investigational product, have measurable disease at 
baseline per RECIST v1.1 or modified MDA criteria for bone-exclusive disease 
and have at least one post-baseline on-study assessment of tumor response (based 
on central read data). This population will be used for the analysis of efficacy data 
based on central read data only.  
• 
Per-Protocol (PP) analysis set: Includes all efficacy evaluable subjects who have 
no major protocol deviations as defined by the Sponsor prior to database lock.

Time since initial diagnosis, time since last recurrence/progression and time since first 
recurrent or metastatic disease will be summarized using descriptive statistics. Time will 
be calculated in months relative to the date of the first infusion. The number and 
percentage of subjects will be presented by the following: stage at diagnosis, status at 
screening, site of recurrence/progression, presence of bone-only disease and any bone 
metastases. A subject will be classed as having any bone metastases if the site of 
recurrence/progression includes the word bone, hip, sternum, vertebra, rib, and/or skull 
and/or the site of metastases includes the word bone hip, sternum, vertebra, rib, and /or 
skull.   
Partial initial diagnosis, recurrence/progression and first recurrent or metastatic disease 
dates will be imputed as follows (to allow times to be calculated for all subjects):  
• 
Missing day will be imputed by the 15th of the month;  Missing day and month 
will be imputed by 1st July.  
For the time since first recurrent or metastatic disease, if a subject has Stage IV disease at 
initial diagnosis with a corresponding M stage of M1 and no date of first recurrent or 
metastatic disease diagnosis date is recorded, the date of initial diagnosis will be used as 
the date of first recurrent or metastatic disease (since Stage IV with an M stage of M1 
indicates metastatic disease at initial diagnosis).

statistics. Time will be calculated in months relative to the date of the first infusion. 
Duration of response is collected on the eCRF.   
Partial last surgery/last radiation treatment dates will be imputed as follows:  
• 
Missing day will be imputed by the 1st of the month;  
• 
Missing day and month will be imputed by 1st January.

Efficacy Evaluation  
7.5.1  
Datasets Analyzed  
All efficacy summaries will be based on the Efficacy Evaluable analysis set (central 
version for central read outputs) and will be repeated using the PP analysis set for the 
primary version of each endpoint (the primary version of each endpoint is the first 
version of the endpoint detailed in each of the sections below, i.e. ORR based on 
confirmed – local assessment is the primary version of ORR). OS data will also be 
repeated using the Safety analysis set. A data listing of subjects excluded from any 
analysis set, to include the reason for exclusion, will be presented.

Primary Efficacy Endpoint Analysis Methods  
The primary efficacy endpoint of objective response rate (ORR) will be performed on the 
Efficacy Evaluable analysis set in each cohort separately. There will be no adjustment for 
multiplicity based on the two cohorts, as each cohort is considered an independent trial.  
The estimate of the ORR will be accompanied by a 2-sided 95% exact binomial 
confidence interval (CI) derived using the Clopper-Pearson method.   
The following sensitivity analyses will be conducted:  
• 
The primary analysis will be repeated using the PP analysis set;  
• 
The primary analysis will be repeated using unconfirmed response;  
• 
The primary analysis will be repeated using central read based on confirmed 
response;  
• 
The primary analysis will be repeated using central read based on unconfirmed

Maximum percentage decrease from baseline in the sum of tumor diameters will be 
displayed in a waterfall plot, by patient and cohort, for all Efficacy Evaluable subjects.   
The estimate of the ORR and associated 2-sided 95% exact binomial CI will also be 
summarized in tabular format and using forest plots for the following subgroups:  
• 
Prior systemic therapy (yes vs no);  
• 
Time since last recurrence (< 6 months vs >= 6 months);

symptom scales (fatigue, pain, and nausea and vomiting), global health status / QoL 
scale, and single items assessing additional symptoms commonly reported by cancer 
patients (dyspnoea, loss of appetite, insomnia, constipation and diarrhoea and perceived

Statistical/Analytical Issues  
7.5.4.1  Adjustments for Covariates No 
covariate adjustments are planned.   
7.5.4.2  
Handling of Dropouts or Missing Data  
The primary analysis of ORR will consider a subject with no evaluable response data to 
be a non-responder.  
Every effort will be made to determine each subject’s progression and survival 
information. However, subjects may withdraw their consent at any time from further 
participation in the study. Subjects may withdraw consent from treatment, survival 
follow-up, or both.   
In analyses presented over time by visit, no imputations will be performed on missing 
data. All analyses will be based on observed data only. The effective sample sizes at each 
assessment visit will be based on the total number of subjects with non-missing data for 
the parameter of interest at that visit.  
Unless otherwise specified, the following general imputation rules will be used for 
missing date in the assessment of an event:  
If all parts of the date are missing, the date will not be imputed. In the case where only 
the start day of an event is missing, it will be replaced by the start day of study treatment

Interim Analyses and Data Monitoring  
Throughout the study, a DMC will monitor safety parameters at regular intervals 
(approximately quarterly) after at least 3 subjects have been treated for at least 1 cycle. 
There was no formal interim analysis undertaken. Multicenter Studies  
This is a multicenter study. Sites in North America, Europe, and Canada are expected to 
participate. All data collected from all study centers will be pooled for data analysis.   
7.5.4.4  
Multiple Comparisons/Multiplicity  
No adjustments for multiple comparisons will be made. A single primary endpoint has 
been identified and each cohort is viewed as a separate study. No adjustment among 
secondary endpoints will be made as this study is exploratory.  
7.5.4.5  
Use of an “Efficacy Subset” of Subjects

population is the subset of the Safety analysis set who have measurable disease at 
baseline and have at least one post-baseline on-study assessment of tumor response.  
The PP analysis set will be utilized as a sensitivity analysis. The PP analysis set will

local laboratory and presented in Système International (SI) units, as suggested by the 
Center for Biologics Evaluation and Research and the Center for Drug Evaluation and  
Research Position on Use of SI Units for Lab Tests (Oct 2013). All data will be included 
in by-subject data listings. Laboratory measurements identified as abnormal (ie, outside 
the normal range) will also be listed separately by subject, laboratory test, and unit.  
Descriptive statistics will be presented for observed values and changes from baseline at 
each visit where parameters were scheduled to be collected per the clinical study 
protocol.   
Where applicable, hematology, chemistry and coagulation results for select parameters 
will be assigned a toxicity grade based on the U.S. Department of Health and Human 
Services Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 (Nov 
2017). Five-by-five contingency tables will be presented for lab tests where toxicity 
grading can be applied to summarize the shift from the baseline grade to the worst 
postbaseline grade. Grades will be presented as none (Grade 0), mild (Grade 1), moderate 
(Grade 2), severe (Grade 3), or life-threatening (Grade 4). Death related to AE (ie, Grade 
5) cannot be determined with available laboratory-based data collection and, thus, will 
not be summarized as a category. Summary results will include the count and percentage 
of subjects within each shift category. Percentages will be based on the number of 
subjects with baseline and at least 1 post baseline assessment.  
Hy’s Law will be used to assess subjects for drug induced liver injury. The criteria for  
Hy’s Law is defined as having an ALT or AST result >3x ULN and Total Bilirubin >2x

12-Lead Electrocardiogram  
Twelve-Lead ECG interval parameters of heart rate, PR interval, RR Interval, QRS 
duration, QT interval, QTcF, and QTcB will be summarized by dose cohort and over all 
subjects combined for the Safety analysis set. Descriptive statistics will be presented for 
observed values and changes from baseline at each visit where parameters were 
scheduled to be collected.  
Twelve-lead ECG will be classified by the investigator as “normal,” “abnormal, not 
clinically significant,” “abnormal, clinically significant.” Three-by-three contingency 
tables will be presented to summarize the shift from the baseline category to the worst 
post-baseline value. Summary results will include the count and percentage of subjects 
within each shift category that had evaluable ECG results. This analysis will be repeated 
for the central interpretation of the ECGs (central read ECGs do not have clinical 
significance assigned so only normal/abnormal will be displayed).  
Prolonged QTcF and QTcB intervals will be summarized as QTc measurements (msec) 
that are > 450, > 480, and > 500 at each visit where ECG is routinely collected per the 
clinical study protocol. Change from baseline categories will also be summarized for 
measurements that represent a change > 30 or > 60 relative to the baseline value.   
7.8.5.3  
ECOG Performance Status  
ECOG exams are to be performed at all study visits.   
ECOG will be summarized by dose cohort and over all subjects combined for the Safety 
analysis set. The shift from the baseline ECOG performance score to the worst 
postbaseline score will be summarized with the number and percentage of subjects in 
each shift category for the Safety analysis set (by dose cohort and over all subjects 
combined). ECOG scores will also be presented in data listings by subject and 
assessment date.  
7.8.5.4  
Physical Examination  
Results of the physical examination will be presented in subject data listings by subject, 
study visit, and body system.  
7.8.5.5  
Prior and Concomitant Medications  
Medications will be coded using the World Health Organization (WHO Drug B3) 
dictionary. Medications entered on the eCRF will be mapped to Anatomic Therapeutic 
Chemical (ATC) drug class (level 4) and drug name.

Prior and concomitant medications will be summarized separately and the study phase of 
each medication will be determined programmatically based on medication start and end 
dates. A prior medication is defined as any medication administered prior to the date of 
the first infusion of investigational product. A concomitant medication is defined as any 
medication administered on or after the date of the first infusion of investigational 
product. A medication may be defined as both prior and concomitant. If it cannot be 
determined whether a medication was received prior to the start of investigational product 
dosing due to partial or missing medication start and/or end dates, it will be considered a 
prior medication. Likewise, if it cannot be determined whether a medication was received 
after the start of investigational product dosing, it will be considered concomitant.  
For the summary of both prior medications and concomitant medications, the number and 
percentage of subjects receiving any medication will be summarized for all subjects in 
the Safety analysis set, as will the number and percentage receiving any medication by 
ATC drug class and generic drug name. Subjects reporting use of more than one 
medication at each level of summarization (any medication received, ATC class, and 
generic drug name) will be counted only once. ATC class terms will be displayed by 
descending order of incidence, as will generic drug names within each ATC class. The 
study phase during which each medication was received (eg, prior, concomitant, or both) 
will be presented on the listing of prior and concomitant medications.  
7.9  
Determination of Sample Size  
The study was initiated as a Simon’s two-stage optimal design. The study passed the 
futility analysis in Stage 1 of the Simon two-stage design and is currently continuing to 
enroll subjects. While the data on Cohort 1 (4 mg QW) is maturing, the study will enroll 
up to a maximum of 45 subjects in Cohort 1 and in parallel will be expanded with the 
addition of Cohort 2 (6 mg QW). The study will continue enrolling a total of 42 subjects 
in Cohort 2, unless an unexpected safety signal emerges that in the judgement of the 
DMC requires analysis and/or poses a serious threat to the well-being of the subject. An 
additional interim look may be undertaken at 50% of the total information fraction (21 
subjects) for Cohort 2.  
The updated design, a 2-look Group Sequential design with stopping for futility based on 
Pocock beta-spending function takes the first look after 21 subjects and has the following 
operating characteristics:

The expansion of Cohort 1 to a maximum of 45 subjects and Cohort 2 to a maximum of 
42 subjects will provide at least 80% power the testing the hypothesis of achieving an 
increase of the response rate from 8% to 25% using a type I error of 5%.

Electronic Record and Signature Disclosure 
Electronic Record and Signature Disclosure created on: 8/22/2018 5:46:09 PM 
Parties agreed to: Gary Gordon, Gill Low 
ELECTRONIC RECORD AND SIGNATURE DISCLOSURE   
From time to time, Precision for Medicine (we, us or Company) may be required by law to 
provide to you certain written notices or disclosures. Described below are the terms and 
conditions for providing to you such notices and disclosures electronically through your 
DocuSign, Inc. (DocuSign) Express user account. Please read the information below carefully 
and thoroughly, and if you can access this information electronically to your satisfaction and 
agree to these terms and conditions, please confirm your agreement by clicking the 'I agree' 
button at the bottom of this document.   
Getting paper copies   
At any time, you may request from us a paper copy of any record provided or made available 
electronically to you by us. For such copies, as long as you are an authorized user of the 
DocuSign system you will have the ability to download and print any documents we send to you 
through your DocuSign user account for a limited period of time (usually 30 days) after such 
documents are first sent to you. After such time, if you wish for us to send you paper copies of 
any such documents from our office to you, you will be charged a $0.00 per-page fee. You may 
request delivery of such paper copies from us by following the procedure described below.  
Withdrawing your consent   
If you decide to receive notices and disclosures from us electronically, you may at any time 
change your mind and tell us that thereafter you want to receive required notices and disclosures 
only in paper format. How you must inform us of your decision to receive future notices and 
disclosure in paper format and withdraw your consent to receive notices and disclosures 
electronically is described below.   
Consequences of changing your mind   
If you elect to receive required notices and disclosures only in paper format, it will slow the 
speed at which we can complete certain steps in transactions with you and delivering services to 
you because we will need first to send the required notices or disclosures to you in paper format, 
and then wait until we receive back from you your acknowledgment of your receipt of such 
paper notices or disclosures. To indicate to us that you are changing your mind, you must 
withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your 
DocuSign account. This will indicate to us that you have withdrawn your consent to receive 
required notices and disclosures electronically from us and you will no longer be able to use 
your DocuSign Express user account to receive required notices and consents electronically from 
us or to sign electronically documents from us.   
All notices and disclosures will be sent to you electronically   
Unless you tell us otherwise in accordance with the procedures described herein, we will provide 
electronically to you through your DocuSign user account all required notices, disclosures, 
authorizations, acknowledgements, and other documents that are required to be provided or 
made available to you during the course of our relationship with you. To reduce the chance of 
you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required 


 
 
notices and disclosures to you by the same method and to the same address that you have given 
us. Thus, you can receive all the disclosures and notices electronically or in paper format through 
the paper mail delivery system. If you do not agree with this process, please let us know as 
described below. Please also see the paragraph immediately above that describes the 
consequences of your electing not to receive delivery of the notices and disclosures 
electronically from us.
