Study Design:
This is a randomized, open-label, multi-center, phase III study of BBI-608 plus weekly 
nab-paclitaxel with gemcitabine (Arm 1) vs. weekly nab-paclitaxel with gemcitabine
(Arm 2) for adult patients with metastatic PDAC.
1132 patients will be randomized in a 1:1 ratio, stratified according to geographical 
region (North America/Western Europe/Australia vs. Japan/Korea vs. Rest of the 
World), Eastern Cooperative Oncology Group (ECOG) performance status (0 vs. 1), 
and presence of liver metastases (yes vs. no). Enrollment was completed prior to this 
amendment.  
Until the time of this amendment, the study proceeded in 28-day (4-week) cycles. BBI-
608 was administered orally, twice daily, with doses separated by approximately 12 
hours. BBI-608 administration began 2-5 days prior to the first nab-paclitaxel with 
gemcitabine infusion. Nab-paclitaxel
125 mg/m2
immediately followed by 
gemcitabine 1000 mg/m2 were administered on Days 1, 8 and 15 of every 28-day cycle
via intravenous infusion.  
From the time of this amendment, and since the outcome of the interim analysis which 
was futile, patients may continue protocol therapy if it is believed to be in their best 
interest by the investigator and patient, and with the patient’s informed consent.
Patients will receive BBI-608, nab-paclitaxel and/or gemcitabine at the same dose and 
schedule that they were receiving prior to the amendment. Patients on Arm 1 may 
continue BBI-608 with the Sponsor’s approval. Patients on Arm 1 may also 
discontinue BBI-608 but choose to continue with nab-paclitaxel and gemcitabine
alone.  
Tumor assessments will be performed every 8 weeks after randomization until 
objective disease progression or treatment discontinuation due to toxicity.
The protocol will continue to be followed for all endpoints until study completion. The 
study is planned for completion on February 28th, 2020. 
Study Population: 
This study will enroll patients with histologically or cytologically confirmed 
adenocarcinoma of the pancreas that is metastatic (Stage IV). Patients with local 
recurrence following surgical resection will be excluded. At randomization, patients 
will not have received systemic chemotherapy for metastatic pancreatic 
adenocarcinoma previously (with a fluoropyrimidine or gemcitabine administered as
a radiation sensitizer in the adjuvant setting allowed). Other inclusion criteria for all 
patients include: age \ears(&2*SHUIRUPDQFHVWDWXVDQGDGHTXDWHKHSDWLF
renal, and bone-marrow function.  
Test Product, 
Dose, and Mode of 
Administration:
Until the time of this amendment, patients randomized to Arm 1 on this study received
BBI-608 orally, daily, at 240 mg bid (480 mg total daily dose). BBI-608 was taken 
daily continuously throughout each 4 week (28 day) study cycle in combination with 
nab-paclitaxel and gemcitabine. BBI-608 was administered twice daily, one hour prior 
or two hours after meals, with the first dose taken in the morning and doses separated 
by approximately 12 hours. 
Patients randomized to Arm 1 received BBI-608 in combination with nab-paclitaxel
and gemcitabine. Patients randomized to Arm 2 received nab-paclitaxel and 
gemcitabine alone. Nab-paclitaxel 125 mg/m2 was administered intravenously starting

on Day 1 of Cycle 1. Gemcitabine 1000 mg/m2 was administered intravenously
following nab-paclitaxel infusion. This regimen was repeated on Days 1, 8 and 15 of 
every 28-day cycle.
Dose modification of BBI-608 and/or nab-paclitaxel and/or gemcitabine was allowed.
There were no dose reductions or adjustments for lymphopenia or alopecia.  
From the time of this amendment, and since the outcome of the interim analysis was 
communicated to investigators, patients may continue protocol therapy if it is believed
to be in their best interest by the investigator and patient, and with the patient’s 
informed consent. Patients will receive BBI-608, nab-paclitaxel and/or gemcitabine at 
the same dose and schedule that they were receiving prior to the amendment. Patients 
on Arm 1 may continue BBI-608 with the Sponsor’s approval. Patients on Arm 1 may 
discontinue BBI-608 but choose to continue with nab-paclitaxel and gemcitabine.. 
Duration of 
Treatment: 
Patients may continue to receive assigned protocol therapy as long as they have not 
experienced any adverse events requiring permanent discontinuation of study 
medication, have not demonstrated disease progression based on Response Evaluation 
Criteria In Solid Tumors (RECIST) 1.1 criteria, it is believed to be in the patient’s best 
interest by the investigator and patient, or until February 28th, 2020, whichever occurs 
first. If nab-paclitaxel and/or gemcitabine is/are discontinued due to toxicity, BBI-608 
may be continued until another discontinuation criterion is met with the Sponsor’s 
approval, if it is believed to be in the patient’s best interest by the investigator and 
patient, and with the patient’s informed consent. If BBI-608 is discontinued due to 
toxicity, nab-paclitaxel and gemcitabine
may be continued until another 
discontinuation criterion is met. 
The study is planned for completion on February 28th, 2020. 
Statistical 
Methods: 
The primary study endpoint is Overall Survival (OS), defined as the time from 
randomization until death from any cause.  
A multiplicity adjustment strategy will be applied to control the overall Type I error 
rate with respect to several sources of multiplicity in the trial. This multiplicity 
adjustment will account for the analysis of the treatment effect on the primary (OS) 
and key secondary (PFS, DCR, ORR) endpoints.
The study is designed to have a power of 90% and a one-sided alpha of 2.5% to detect 
a 20% reduction in the continuous risk of death (HR 0.80, which corresponds to an 
increase of median survival from 8.5 to 10.63 months) in the Intention to Treat (ITT) 
general study population. It is estimated that 864 events will be required to detect this 
reduction which would be observed by randomizing 1132 patients enrolled over 24 
months with patient follow up for an additional 12 months, for total study duration of 
36 months. It is anticipated that up to 5% dropout rate will occur for the entire study.  
The primary hypothesis is: 
H0: BBI-608 + nab-paclitaxel with gemcitabine QDE-paclitaxel with gemcitabine 
versus
H1: BBI-608+ nab-paclitaxel with gemcitabine > nab-paclitaxel with gemcitabine. 
This hypothesis will be evaluated for the superiority of BBI-608 by performing a 
stratified log-rank test adjusting for the stratification variables at randomization. The 
final analysis will be performed when 864 OS events have been observed.

The overall power of the study will be approximately 90% after the multiplicity control 
procedure is considered.
Prior to this amendment, there was one interim analysis presented to the independent 
Data Safety and Monitoring Board (DSMB). Additionally, the DSMB reviewed safety 
during conduct of the study. The role and responsibility of the DSMB are defined in a 
separate Charter.
The interim analysis involved a stratified log-rank test. Nominal p-values were based 
on the Lan-DeMets error spending function using an O’Brien-Fleming stopping 
boundary in order to preserve the overall one-sided alpha level at 0.025.  
The interim analysis was performed when approximately 432 deaths (50% of the 
required events) were observed. The interim analysis was for futility only, with the
futility boundary set at HR > 1.

BACKGROUND INFORMATION AND RATIONALE
2.1
PANCREATIC DUCTAL ADENOCARCINOMA
Pancreatic ductal adenocarcinoma (PDAC) is the most common form of pancreatic cancer with the 
worst prognosis of all solid tumors (Corbo, 2012; Klimstra, 2007). PDAC is the fourth leading cause 
of cancer death in the United States with an estimate of 38,460 deaths closely following the number
of 45,220 diagnoses in 2013 (Siegel, 2013). Surgery is considered the only potentially curative 
treatment, however, more than 80% of patients present with locally advanced or metastatic disease 
(Davis, 2012). Out of the minority of presenting patients who qualify for curative surgery, most will 
develop disseminated advanced disease with a 5-year survival rate of less than 5% (Hidalgo, 2010).
Standard treatment for unresectable and metastatic disease currently includes first-line combination 
regimen with FOLFIRINOX (5-FU, leucovorin, irinotecan and oxaliplatin), a regimen that provides a 
median overall survival (OS) of 11.1 months in patients with treatment-naïve disease (Conroy, 2011).
Moreover, a number of uncontrolled studies have shown that modified FOLFIRINOX 
(mFOLFIRINOX) regimen results in decreased toxicity while maintaining efficacy in patients with 
pancreatic adenocarcinoma (Blazer, 2015; Mahaseth, 2013). Most recently, a liposomal irinotecan 
formulation was shown to improve overall survival by 1.9 months (6.1 months vs 4.2 months) in 
combination with 5-FU and leucovorin in patients with metastatic PDAC progressing on gemcitabine-
based first-line treatment as compared to patients treated with 5-FU and leucovorin alone (Chen, 2015). 
An alternative regimen for this patient population is a combination of nab-paclitaxel with gemcitabine.
A recent updated survival analysis of the phase II/III study, MPACT (Von Hoff, 2013), randomizing 
861 patients with metastatic PDAC to gemcitabine versus gemcitabine in combination with nab-
paclitaxel, revealed a sustained difference in OS between the 2 arms with median survival of 8.7 
months in the combination group compared to 6.6 months in the gemcitabine monotherapy group and 
more importantly a first ever 3-year survival rate of 4% in the combination treatment group (Goldstein,
2014). These results encourage continued efforts to build upon these backbones to further extend 
survival. Currently, a patient with advanced disease progressing in first-line therapy has limited 
treatment options. Given the morbidity associated with this disease, there is an urgent need to identify 
novel therapies to improve the outcome of patients with advanced unresectable PDAC. 
2.2
CANCER STEM CELLS (CSC) AND PDAC
CSCs or cancer cells with stemness phenotypes are a sub-population of cancer cells that have self-
renewal capability, are highly malignant and are considered to be fundamentally responsible for 
malignant growth, recurrence, drug-resistance and metastasis. Moreover, CSCs are highly resistant to 
chemotherapies and current targeted agents. CSCs have been isolated from almost all major tumor 
types, including PDAC (Lee, 2008; Boman, 2008; Clevers, 2011; Gupta, 2009; Hanahan, 2011; 
Gupta, 2011).
Accumulating evidence indicates that CSCs may play a key role in the pathogenesis of PDAC (Lee, 
2008). Cancer stem cells have been isolated from human pancreatic adenocarcinomas using a
combination of three cell surface markers including CD44, CD24, and ESA (Li, 2007). These CSCs 
isolated from pancreatic adenocarcinoma patients display tumour-initiating properties (Shah, 2007; Li, 
2007). Additionally, the CD133 cell surface marker also discriminates for pancreatic cancer cells with 
potent proliferative capacity (Hermann, 2007) and pancreatic cancer cells positive for both CD133 and 
CXCR4 cell surface markers have the ability to migrate and metastasize in addition to having a potent

CONFIDENTIAL
proliferative capacity (Hermann, 2007). Moreover, CSCs in PDAC display resistance to therapeutics 
as it has been observed that treatment with ionizing radiation and chemotherapy results in enrichment 
of cancer stem cells in pancreatic adenocarcinoma. Exposure of pancreatic cancer cell line to 
gemcitabine results in enrichment of the CSC population (Hermann, 2007; Hong, 2009). Finally, as is 
the case with other cancers including colorectal, breast, prostate, and ovarian carcinoma, expression 
of CSC markers in pancreatic tumors correlates with diminished survival (Rasheed, 2012; Maeda, 
2008; Ohara, 2013). These findings suggest that the development of cancer stem cell inhibitors may 
represent a novel strategy for potential use in the treatment of PDAC.
2.3
BBI-608 
BBI-608 (also called napabucasin, BBI608, BB608) is a small molecule that is hypothesized to affect 
multiple oncogenic cellular pathways, including inhibition of the STAT3 pathway, which has been 
implicated in cancer stem cell viability. For further pre-clinical information, please refer to the 
Investigator Brochure.
BBI-608 has been evaluated in multiple clinical trials as both a monotherapy and as a component of 
combination therapy with standard anti-cancer therapeutics. Available data from many of these trials, 
including detailed adverse event (AE) tables and pharmacokinetic information, can be found in the IB.  
Highlighted below are general information on the BBI-608 safety profile and a summary of the 
BBI608-118 (aka BBI608-201PANC) phase I/II clinical trial of BBI-608 in combination with standard 
chemotherapy for advanced PDAC.
2.3.1
Pre-Clinical Rationale
The pre-clinical rationale for the development of BBI-608 can be found in the Investigator Brochure. 
2.3.2
Safety Profile
The predominant adverse drug reactions (ADRs) associated with BBI-608 are gastrointestinal in 
nature. BBI-608 appears to irritate the gastrointestinal epithelium, which can result in diarrhea, 
abdominal pain, nausea, vomiting, and decreased appetite (anorexia). Fatigue is also reported.  
These ADRs are predominantly mild (grade 1 or grade 2), but can be severe (grade 3). Gastrointestinal 
or other ADRs that are grade 4 in severity are rare (<1%). However, even mild or moderate events, if 
persistent, can result in dehydration; which, if severe, can lead to other events such as hypovolemia, 
hypotension, electrolyte abnormalities, and increased serum creatinine/acute kidney injury. Other 
sequelae such as dizziness or falls could also occur.  
The common ADRs for BBI-608 are shown in Table 1 below. The table shows two sets of frequencies 
or rates. The first set (3rd column) is the range of rates reported for each event as a non-serious 
occurrence across the clinical trials. Different rates are observed in each trial because of different study 
populations and the different combination therapeutics involved. The second set of rates (4th column) 
is the overall frequency in which the event is reported as a serious adverse drug reaction.

2.3.3
BBI-608 for Pancreatic Cancer 
The BBI608-118 (aka BBI608-201PANC) study was initiated to evaluate BBI-608 in combination 
with standard chemotherapy for advanced PDAC. The primary objectives of the study included 
determination of the safety, tolerability, pharmacokinetic characteristics, and recommended phase II 
dose (RP2D) of BBI-608 in combination with each of the backbone regimens. Secondary objectives 
included evaluation of preliminary anti-tumor activity. The study has completed accrual and analysis 
is ongoing. 
Patients with PDAC were eligible if they were appropriate to receive treatment with one of several 
standard regimens for advanced pancreatic cancer: albumin-bound paclitaxel (nab-paclitaxel) plus 
gemcitabine, FOLFIRINOX, liposomal irinotecan (Onivyde [MM-398]) plus 5FU/Leucovorin, or 
FOLFIRI. The trial was not randomized and a treatment arm was selected by investigators based on 
the specific clinical context for each patient. 
Once enrolled, patients received twice daily administration of BBI-608 in combination with a standard 
chemotherapeutic backbone as set forth above. RP2D was determined to be 240 mg BID (480 mg total 
daily) for all combination arms. 
In the BBI-608 in combination with gemcitabine plus nab-paclitaxel study arm, patients received 
gemcitabine 1000 mg/m2 intravenously plus nab-paclitaxel 125 mg/m2 intravenously on days 1, 8, and
15 of a 28-day study cycle. Dose adjustment of either BBI-608 or gemcitabine/nab-paclitaxel (either 
agent) was permitted in the event of toxicity.
Out of 71 patients enrolled, a total of 66 patients had not previously received BBI-608. A majority of 
these patients had not received any systemic therapy, with approximately 25% having received 
adjuvant therapy with recurrence at less than 6 months of the last adjuvant dose.  
As of September 1, 2017, 64 out of the 66 patients enrolled had protocol treatment dose-administration 
confirmed in the study database. These 64 patients were included in an analysis of safety and efficacy. 
Objective response per RECIST 1.1 was observed in 31 (48%) of patients, including 2 (3%) with 
complete response (CR) and 29 (45%) with partial response (PR). An additional 19 (30%) patients had

stable disease (SD), and the disease control rate (DCR, proportion with CR, PR, or SD per RECIST 
1.1) was 78%. There were 39 (61%) patients with a progression event and 43 (67%) patients who died, 
with a median progression-free survival (mPFS) of 7.4 months and a median overall survival (mOS) 
of 10.9 months.  
Adverse events (AEs) in the clinical database as of September 1st, 2017 and observed in at least 10% 
of study patients are presented in Table 2 below. Updated clinical data from this trial, if available, can 
be found in the IB.

BBI-608 at a dose of 240 mg BID (480 mg total daily) combined with a standard regimen of 
gemcitabine and nab-paclitaxel was tolerated in patients with advanced pancreatic cancer.  The clinical 
activity observed in the BBI608-118 (BBI608-201PANC) study, paired with the unmet medical need 
for additional effective therapies in pancreatic cancer, provides a rationale for further clinical 
investigation. CanStem111P is designed to evaluate the role of BBI-608 in combination with nab-
paclitaxel and gemcitabine as frontline therapy for metastatic PDAC.

TRIAL DESIGN
This is an international multi-center, prospective, open label, randomized phase III trial of BBI-608 
plus nab-paclitaxel with gemcitabine (Arm 1) versus nab-paclitaxel with gemcitabine (Arm 2) in adult 
patients with metastatic pancreatic adenocarcinoma.
Following the interim analysis, the trial will continue with patients who have not yet achieved the 
primary study endpoint (death), and with patients currently on protocol therapy and who may receive 
BBI-608 and/or gemcitabine and/or nab-paclitaxel on study based on the clinical judgement of the 
investigator that this is in the patient’s best interest, provided the patient is fully informed, in agreement
and has provided consent. Patients will receive protocol treatment until any of the discontinuation 
criteria are met or until February 28th, 2020, whichever occurs first. The protocol will continue to be 
followed for all endpoints until study completion.

on Days 1, 8 and 153
1
BBI-608 should be taken one hour before or two hours after a meal, two times daily, with approximately 12 
hours between doses. BBI-608 administration will begin 2 days prior to the backbone chemotherapy infusion 
on Day 1 of Cycle 1. These two days are referred to as Run-in Day 1 and Run-in Day 2. The Run-in period 
may be extended by up to 3 additional calendar days. Run-in Day 1 should occur within 2 calendar days of 
patient randomization.
2
Patients should be encouraged to maintain sufficient fluid intake while on protocol treatment, such as taking 
BBI-608 with approximately 250 mL of fluid over the course of 30 minutes after the dose.
3
Nab-paclitaxel 125 mg/m2 will be administered intravenously over approximately 30 minutes starting on Day 
1 of Cycle 1, at least 2 hours after the first daily dose of BBI-608. Gemcitabine 1000 mg/m2 will be 
administered intravenously over approximately 30-60 minutes immediately following nab-paclitaxel 
infusion. The infusions will repeat on Days 1, 8 and 15 of every 28-day cycle. 
4
If nab-paclitaxel and/or gemcitabine is/are discontinued due to toxicity, BBI-608 may be continued as 
monotherapy until another criterion for stopping treatment is met with the Sponsor’s approval, if it is believed
to be in the patient’s interest by the investigator and patient, and with the patient’s informed consent. If BBI-
608 is discontinued due to toxicity, nab-paclitaxel and gemcitabine may be continued until another criterion 
for stopping treatment is met.
5
If at the time of disease progression based on RECIST 1.1 criteria on nab-paclitaxel and gemcitabine with 
BBI-608, the patient has not experienced any adverse events requiring permanent discontinuation of BBI-
608, the patient is not a candidate for second-line chemotherapy, it is believed to be in the patient’s best
interest by the investigator and patient, and with the patient’s informed consent, BBI-608 may be continued 
in monotherapy following discontinuation of nab-paclitaxel and gemcitabine with the Sponsor’s approval.
3.3
INCLUSION OF WOMEN AND MINORITIES
Patients enrolled in this study will be representative of the mix of genders, races and ethnicities seen 
in the general population of patients with PDAC. The effect of the intervention under investigation 
will be analyzed in gender, racial and ethnic subgroups, with recognition of the potentially limited 
statistical power of this analysis.

INCLUSION CRITERIA
Questions about eligibility criteria should be addressed prior to randomization. 
The eligibility criteria for this study have been carefully considered. Eligibility criteria are standards 
used to ensure that patients who enter this study are medically appropriate candidates for this therapy, 
as well as to ensure that the results of this study can be useful for making treatment decisions regarding 
other patients with similar diseases. 
Eligibility criteria will be verified by the sponsor and/or sponsor designee prior to patient 
randomization. 
Patients must fulfill all of the following criteria to be eligible for admission to the study:
4.1.1
Written, signed consent for trial participation must be obtained from the patient appropriately 
in accordance with applicable ICH guidelines and local and regulatory requirements prior to 
the performance of any study specific procedure.
4.1.2
Must have histologically or cytologically confirmed advanced PDAC that is metastatic. The 
definitive diagnosis of metastatic PDAC will be made by integrating the histopathological data 
within the context of the clinical and radiographic data. Patients with islet cell neoplasms are 
excluded. 
4.1.3
Must not have previously received chemotherapy or any investigational agent for the treatment 
of PDAC.
x
A fluoropyrimidine or gemcitabine administered as a radiation sensitizer in the adjuvant 
setting is allowed for as long as last dose was administered > 6 months prior to 
randomization and no lingering toxicities are present. 
4.1.4
Nab-paclitaxel with gemcitabine therapy is appropriate for the patient and recommended by 
the Investigator.
4.1.5
Patient has one or more metastatic tumors evaluable by CT scan with contrast (or MRI, if 
patient is allergic to CT contrast media) per RECIST 1.1. Imaging investigations including 
CT/MRI of chest/abdomen/pelvis or other scans as necessary to document all sites of disease
must be performed within 14 days prior to randomization. Qualifying scans performed as part 
of standard of care prior to patient signature of the study informed consent will be acceptable 
as baseline scanning as long as scanning is performed < 14 days prior to randomization. 
4.1.6
Must have ECOG Performance Status of 0 or 1, assessed within 14 days prior to 
randomization. Two observers qualified to perform assessment of the performance status will 
be required to perform this assessment. If discrepant, the one with the most deteriorated 
performance status will be considered true.

Patients must not require any help with activities of daily living (ADLs), including eating, 
dressing, washing or using the toilet.  
x
Patients must not need to stay in bed or chair for 50% or more of waking hours. 
x
Patients with factors that limit accurate assessment of performance status will not be 
eligible for the study. This includes but is not limited to patients with pre-existing 
conditions preventing them from full mobility (including but not limited to spinal or 
orthopedic conditions, amputees, morbid obesity defined by BMI > 40).

Due to increased risk of sepsis in patients >80 years old, candidate patients in this age 
group should be thoroughly evaluated prior to study randomization to ensure they are fit 
to receive chemotherapy. In addition to all of the inclusion/exclusion criteria listed, 
clinical judgment should be used regarding patients’ susceptibility to infection (including 
but not limited to presence of ascites or diabetes mellitus increasing risk of infection). 
Furthermore, the expected stability of their performance status while receiving repeat 
weekly chemotherapy cycles should be given special attention. Patients in this age group 
should not be randomized on the study should there be any hesitation on any of these 
considerations. 
4.1.9
For male or female patients of child producing potential: Must agree to use contraception or 
take measures to avoid pregnancy during the study and for 180 days after the final dose of 
nab-paclitaxel and gemcitabine or for 30 days for female patients and for 90 days for male 
patients, after the final BBI-608 dose if nab-paclitaxel and gemcitabine were not administered.

marker assays proscribed in Section 13.6 (Correlative Studies) may be conducted. 
4.1.21 Patients must be accessible for treatment and follow-up. Patients registered on this trial must 
receive protocol treatment and be followed at the participating center. This implies there must 
be reasonable geographical limits placed on patients being considered for this trial. 
Investigators must ensure that the patients randomized on this trial will be available for 
complete documentation of the treatment, response assessment, adverse events, and follow-
up.

patients who halted screening previously without having failed any of the screening tests/evaluations 
or inclusion criteria for this study. Otherwise, re-screening will not be allowed. 
Any questions regarding patient eligibility should be directed to Sponsor or other Sponsor-nominated 
designee for written approval.  
Additional testing will be repeated < 72 hours prior to randomization: ECOG performance status (PS),
vital signs, weight, concurrent medication list and serum albumin will be repeated at < 72 hours prior 
to randomization after first being performed as part of Baseline testing. Total bilirubin will be repeated 
< 72 hours prior to randomization for patients with total bilirubin > 1 and < 1.5 x ULN at Baseline 
testing with at least 7 days between Baseline and repeat assessments.

ENTRY/RANDOMIZATION PROCEDURES
6.1
ENTRY PROCEDURES
Repeat of screening laboratory testing will be allowed only in case of laboratory error. Otherwise, re-
screening will not be allowed for patients who screen fail during initial screening procedures. 
Following Sponsor approval of patient eligibility pre-randomization, patients will be randomized. All 
randomizations will be done through the randomization and trial supply management (RTSM) system.
Complete details regarding obtaining a password, accessing the system and registering/randomizing 
patients will be provided at the time of study activation.  
All patients screened for the study by the participating treatment center will be assigned a subject 
screening number and all eligible patients enrolled on the study will be assigned an additional subject 
randomization number; these must be used on all documentation and correspondence. 
The following information will be required:
x
patient’s date of birth (as allowed by local regulations) and age 
x
patient's initials (as allowed by local regulations)  
x
confirmation of the requirements listed in sections 4.1 and 4.2 
x
stratification factors 
6.2
STRATIFICATION
The permuted block randomization procedure will balance between treatment arms within each of the 
following stratification factors:
x
Geographical region (North America/Western Europe/Australia vs. Japan/Korea vs. Rest of the 
World)  
x
ECOG performance status (0 vs. 1)
x
Presence of liver metastases (yes vs. no)
6.3
RANDOMIZATION
Patients will be randomized 1:1 between the two treatment arms and the randomization will be 
provided electronically (via RTSM). 
Note: The validity of results of the trial depends on the authenticity of, and the follow-up of, all 
patients entered into the trial. Under no circumstances, therefore, may an allocated patient’s data be 
withdrawn prior to final analysis, unless the participant withdraws from the trial and requests that data 
collection/submission cease from the point in time of withdrawal.
All eligible patients randomized to the trial will be followed by the coordinating center. It is the 
responsibility of the physician investigator to have full satisfaction in that the patient is indeed eligible 
before requesting randomization.

PROTOCOL TREATMENT
7.1
TREATMENT PLAN
Protocol treatment is to begin within 2 calendar days of patient randomization for patients randomized 
to Arm 1. Patients randomized to Arm 2 must begin protocol treatment within 7 calendar days of 
randomization. 
Palliative and supportive care for other disease-related symptoms and for toxicity associated with 
treatment will be permitted for all patients on this trial. Details of interventions (e.g. medications such 
as antibiotics, analgesics, antihistamines, steroids, G-CSF, erythropoietin), procedures (e.g. 
paracentesis, thoracentesis), or blood products (e.g. blood cells, platelets, or fresh frozen plasma 
transfusions) should be recorded on the case report forms.
Patients may continue to receive assigned protocol therapy until any of the discontinuation criteria are 
met or until February 28th, 2020, when the study is planned for completion, whichever occurs first.
7.2
DRUG ADMINISTRATION
One treatment cycle is defined as 4 weeks (28 days) with BBI-608 administered continuously, and 
nab-paclitaxel with gemcitabine administered weekly for 3 consecutive weeks with the fourth week 
off. BBI-608 administration will begin 2 days prior to the first nab-paclitaxel and gemcitabine infusion 
administered on Day 1 of Cycle 1. These two days are referred to as Run-In Day 1 and Run-In Day 2. 
The Run-in period may be extended by up to 3 additional calendar days. In case of gastrointestinal 
toxicity secondary to BBI-608, administration of nab-paclitaxel with gemcitabine may be delayed for 
as long as necessary until resolution of symptoms.

If either nab-paclitaxel and/or gemcitabine is discontinued due to toxicity, BBI-608 may be continued as 
monotherapy until another criterion for stopping treatment is met with the Sponsor’s approval, if it is believed to 
be in the patient’s best interest by the investigator and patient, and with the patient’s informed consent. If BBI-608
is discontinued due to toxicity, nab-paclitaxel and/or gemcitabine may be continued until another criterion for 
stopping treatment is met.
5
If at the time of disease progression based on RECIST 1.1 criteria on nab-paclitaxel and gemcitabine with BBI-
608, the patient has not experienced any adverse events requiring permanent discontinuation of BBI-608,the patient 
is not a candidate for second-line chemotherapy, it is believed to be in the patient’s best interest by the investigator 
and patient, and with the patient’s informed consent, BBI-608 may be continued in monotherapy following 
discontinuation of nab-paclitaxel and gemcitabine with the Sponsor’s approval. 
Patients will receive BBI-608 two times daily, approximately one hour prior to or two hours after 
meals, with the first dose given in the morning and the second dose given approximately 12 hours 
later.
Detailed instructions for the preparation, premedication, and administration of nab-paclitaxel with 
gemcitabine are provided in the Product Labels approved by US FDA and/or Summary of Product 
Characteristics. Nab-paclitaxel 125 mg/m2 will be administered intravenously over approximately 30 
minutes starting on Day 1 of Cycle 1, following the first dose of BBI-608. Gemcitabine 1000 mg/m2
will be administered intravenously over approximately 30-60 minutes immediately following nab-
paclitaxel infusion. The infusions will repeat on Day 1, 8 and 15 of every 28-day cycle. In case of 
toxicity, dose adjustment is permitted.  
If either gemcitabine and/or nab-paclitaxel is/are permanently discontinued due to toxicity, BBI-608 
may be continued as monotherapy until another criterion for stopping treatment is met with the 
Sponsor’s approval, it is believed to be in the patient’s best interest by the investigator and patient, and 
with the patient’s informed consent. If BBI-608 is permanently discontinued due to toxicity, nab-
paclitaxel with gemcitabine may be continued until another criterion for stopping treatment is met.

The major adverse events associated with the use of BBI-608 are gastrointestinal events (nausea, 
diarrhea, and abdominal cramping) and fatigue. Fatigue is often secondary to gastrointestinal events. 
There is no hematologic toxicity associated with BBI-608. We strongly recommend that pre-existing 
laxative bowel regimens, such as stool softeners, be held starting the day prior to first dose of study 
treatment and may be resumed in cases of no bowel movement during the first 2 days of protocol 
treatment. Fiber supplementation may be continued. Additionally, prophylactic anti-diarrheal 
medications, such as Loperamide and/or Diphenoxylate/Atropine, starting 1 day prior to start of BBI-
608 are strongly recommended for all patients without history of constipation (just prior to 
randomization) for the first 4 weeks of study treatment with BBI-608. Antidiarrheal prophylaxis should 
be held if constipation develops. Details regarding the use of prophylactic medication for the 
management of common BBI-608 related gastrointestinal adverse events are specified in the 
supplementary Adverse Event Management handout as well as in the Pharmacy Manual.
No hematologic toxicity related to BBI-608 treatment has been observed.

Anti-Emetic Prophylaxis
Initial antiemetic prophylaxis is strongly recommended with a 5HT3 agent (PO or IV) in combination 
with dexamethasone 8 or 10 mg (PO or IV) prior to administration of Gemcitabine. Dexamethasone 
may be continued at the dose of 4 mg twice daily or three times daily for 3-4 days at the Investigator’s 
discretion. If a patient experiences nausea and/or vomiting following the first dose, Institutional 
guidelines and Investigator’s recommendations should be followed for breakthrough antiemetic 
management.  
Hematopoietic Support Administration
G-CSF support may be given according to Institutional standards for the treatment of neutropenia 
and/or thrombocytopenia, neutropenic fever or infections associated with neutropenia and for the 
prevention of febrile neutropenia in patients with an ANC < 500 cells/ml. Patients not experiencing 
resolution of neutropenia within 21 days, despite uninterrupted granulocyte stimulating factor 
treatment, will discontinue study treatment. Erythropoietin may be administered at the discretion of 
the Investigator, consistent with Institutional guidelines.

Sepsis Prophylaxis 
At the first occurrence of fever > 38.5 0C, patients should be instructed to immediately contact their 
physician. Prophylactic institution of broad-spectrum antibiotics (such as amoxicillin/clavulanate 500 
mg PO 2-3 times daily) should be considered for febrile patients at the Investigator discretion and/or 
as per Institutional standards. On day of randomization, patients should be provided with enough 
antibiotic for use at home, and they should be instructed to begin taking it when they first record a 
temperature of > 38.5 0C (or if they feel they are developing a fever and a thermometer is not available). 
They should also immediately contact their physician for guidance on where to go for blood counts to 
be evaluated for sepsis as soon as possible. Hospitalization or evaluation in the emergency room may 
be required depending on their clinical presentation. Administration of prophylactic antibiotics to 
otherwise uncomplicated patients with biliary stents will be at the discretion of the Investigator. Biliary 
stents should be monitored closely to determine need for replacement. 
Due to increased risk of sepsis in patients >80 years old, candidate patients in this age group should 
be carefully followed clinically throughout study treatment. This patient population will also be 
carefully monitored by the independent DSMB. 
7.4
BBI-608 DOSE MODIFICATION
The major adverse events associated with the use of BBI-608 are gastrointestinal events (nausea, 
diarrhea, and abdominal cramping) and fatigue. Fatigue is often secondary to gastrointestinal events. 
There is no hematologic toxicity associated with BBI-608. We recommend that pre-exiting laxative 
bowel regimens, such as stool softeners, be held starting the day prior to first dose of BBI-608 
treatment and may be resumed in cases of no bowel movement during the first 2 days of BBI-608 
treatment. Fiber supplementation may be continued. Additionally, prophylactic anti-diarrheal 
medications, such as Loperamide and/or Diphenoxylate/Atropine, starting 1 day prior to start of BBI-
608 are strongly recommended for all patients treated with BBI-608. 
The guidelines that follow outline dosing modifications and recommended interventions should the 
above adverse events occur. 
Adverse events will be graded using the NCI Common Terminology Criteria for Adverse Events 
(CTCAE) Version 4.0 (see Appendix IV). If a patient experiences several adverse events and there are 
conflicting recommendations, please use the recommended dose adjustment that reduces the dose to 
the lowest level.
BBI-608 Dose Modification Recommendations For Gastrointestinal Adverse Events:

Recommended symptom-specific supportive treatment for common BBI-608-related adverse events is 
as follows (unless contraindicated). Prophylactic anti-diarrheal medications, such as Imodium and/or 
lomotil, starting 1 day prior to start of BBI-608 are strongly recommended for all patients: 
BBI-608 GI Toxicity/Adverse Event Supportive Treatment:
Diarrhea & Abdominal Cramping
Nausea, Vomiting, or Anorexia
Dicyclomine (e.g., Bentyl): Recommended when the 
predominant issue is cramping or abdominal pain

Dexamethasone (Decadron), ideally in 
combination with a 5HT3-inhibitor. Short term use 
can be very effective
Systemic opioids (e.g. Dilaudid, Codeine): have been 
found effective in reducing abdominal pain and watery 
diarrhea
Other  agents: anti-histamines, benzodiazepines, 
proton pump inhibitors/H2 antagonists, dopamine 
antagonists, and cannabinoids

adverse events are specified in the supplementary Adverse Event Management handout as well as in 
the Pharmacy Manual.
7.4.1
Hematologic Adverse Events
No hematologic toxicity related to BBI-608 treatment has been observed. Should a study subject 
experience a Grade 1 or 2 hematologic adverse event, dosing may continue while an alternate 
explanation is sought and/or a therapeutic intervention is undertaken.  
In the unlikely event of a Grade 3 or 4 hematologic adverse event, continued dosing will be at the 
discretion of the study Investigator. Since a Grade 3 or 4 hematologic event attributed to BBI-608 has 
not been reported, a prompt evaluation for an alternate explanation is strongly recommended.  
7.4.2
Non-Hematologic (Gastrointestinal) Adverse Events
The dose modifications above should be followed in the occurrence of gastrointestinal adverse events 
or in the event of their sequelae. BBI-608 dose modification should not be followed for non-
gastrointestinal events as they are not expected with use of BBI-608. Toxic effects will be graded using 
the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 (Appendix IV).  
7.4.3
Other Situations 
Change in Urine Color and Odor: Occasionally, subjects have reported an orange-brown color change 
to their urine. Rarely, subjects also report a new odor to their urine. All subjects should be made aware 
of the possibility of these effects. Dosing can be continued in the presence of these events. 
7.5
NAB-PACLITAXEL AND GEMCITABINE DOSE MODIFICATION
Dose modifications for hematologic and non-hematologic toxicities (using NCI CTCAE Version 4.0) 
expected from nab-paclitaxel with gemcitabine
should be performed according to the 
recommendations outlined below. Dose modifications for non-gastrointestinal toxicities expected 
from nab-paclitaxel with gemcitabine may also follow institutional guidelines. There will no dose 
reductions or adjustments for lymphopenia or alopecia. Dose level modifications of nab-paclitaxel and 
gemcitabine will occur at two dose levels. Any toxicity requiring dose level modification beyond the 
second dose modification warrants treatment discontinuation. Any further dose modification may be 
allowed in line with clinical practice per Sponsor and Investigator agreement..  
When a dose reduction is required, no dose reescalation will be permitted for the duration of study 
treatment (with exception for hematologic toxicity on Day 15 when re-escalation with G-CSF support 
is permitted following a dose reduction on Day 8 of the same cycle).

If patients do not experience resolution of neutropenia within 21 days, despite uninterrupted G-CSF treatment, study 
treatment will be discontinued.
7.5.2
Other Non-Hematologic Toxicities
Dose modification for other toxicities specified below expected from nab-paclitaxel with gemcitabine

For treatment of Grade 3-4 nausea/vomiting, Initial antiemetic prophylaxis is recommended with a 5HT3 agent (PO or 
IV) in combination with dexamethasone 8 or 10 mg (PO or IV) prior to administration of gemcitabine to be continued 
at 4 mg BID or TID for 3-4 days at the Investigator’s discretion. Institutional guidelines and Investigator’s 
recommendations should be followed for breakthrough antiemetic management. BBI-608 dosing modification as 
outlined in Section 7.4 may be appropriate depending on the judgment of the Investigator.
2
Grade 2 or 3 cutaneous toxicity on Day 1 of any cycle requires reduction of both nab-paclitaxel and gemcitabine to the 
next lower Dose Level. If Grade 2-3 cutaneous toxicity recurs despite dose reduction, treatment should be discontinued. 
3
For Grade > 3 neuropathy, nab-paclitaxel treatment should be held and gemcitabine may be continued. Nab-paclitaxel 
treatment may be resumed at next lower level if neuropathy improves to < Grade 1. Discontinuation of treatment with 
nab-paclitaxel is recommended in cases of peripheral neuropathy resulting in > 21 day delay in nab-paclitaxel 
administration unless not deemed appropriate in the judgment of the Investigator.
4
Except for mild or asymptomatic pulmonary embolism treated with low-molecular-weight heparin without interruption 
of therapy. Moderate to severe pulmonary embolism will require permanent discontinuation of treatment.
5
For initial treatment of Grade 3-4 diarrhea/mucositis BBI-608 dosing modification may be initiated as per Section 7.4 
prior to modification of backbone chemotherapy dosing.
When laboratory parameters or adverse events indicate that either or both nab-paclitaxel and/or 
gemcitabine infusions should be delayed, the infusions scheduled for that day are not given. The 
infusions will be considered skipped and not made up. The next infusion will be administered on the 
following scheduled infusion day if the toxicity is resolved to an acceptable level. Laboratory 
parameters should be evaluated prior to the next scheduled infusion and actions taken according to the 
protocol parameters.
If toxicity is thought by the Investigator to be related to both BBI-608 and nab-paclitaxel and

gemcitabine, then the dose modification rules for both treatment regimens should be followed.
If either gemcitabine and/or nab-paclitaxel is/are held or discontinued for toxicities solely related to 
gemcitabine and/or nab-paclitaxel, BBI-608 therapy may be continued until another discontinuation 
criterion for stopping therapy is met with the Sponsor’s approval, if it is believed to be in the patient’s 
best interest by the investigator and patient, and with the patient’s informed consent. 
If BBI-608 is permanently discontinued due to toxicity, nab-paclitaxel and gemcitabine therapy may
be continued until another discontinuation criterion for stopping therapy is met.

BLINDING/UNBLINDING
This is an open label study. The primary endpoint of this study is overall survival, the assessment of 
which is unlikely to be impacted by the open-label nature of the study. 
However, to comply with ICH E6 (R2) Guideline for Good Clinical Practice (2016) recommending 
the

review 
of 
planned 
analyses 
[http://www.ich.org/fileadmin/Public_Web_Site/ICH_Products/Guidelines/Efficacy/E6/E6_R2__Ste

a blinding plan was implemented by the Sponsor and by the CRO to maximize the integrity of the 
study. The Sponsor  blinding plan outlines the internal communication processes, data access levels, 
and firewalls that will be utilized to achieve study blinding internally. 
7.7
PATIENT MONITORING
For the duration that patients are on study therapy, adverse event monitoring will be done continuously. 
Patients will be evaluated for adverse events at each visit, and are to be instructed to call their physician 
to report any adverse events between visits.
7.8
CONCOMITANT MEDICATIONS/PROCEDURES
7.8.1
Permitted Treatments
All information regarding concomitant treatments (medications or procedures) must be recorded on 
the patient’s CRF (including the name of the medication or procedure and duration of treatment).  
Palliative and supportive care is permitted for disease-related symptoms for all patients. 
All palliative and supportive care measures may be administered to patients in any study arm at the 
Investigator’s discretion. Incident palliative radiotherapy is permitted in any study arm while on study, 
but requirement of radiation to the target lesion(s) will qualify the patient as having disease 
progression. 
Overall, CYP isoenzymes have an insignificant role in the biotransformation of BBI-608. The CYP 
P450 isoform 1A2 is the predominant isoform involved in the drug’s metabolism. Although the 
following drugs are permitted while on study treatment, all reasonable measures should be done to 
avoid use of drugs that are strong inhibitors of CYP1A2 unless there is medical necessity for their use.

Strong CYP1A2 inhibitors include:  
o
Ciprofloxacin and other fluoroquinolones 
o
Fluvoxamine 
o

o
Zafirlukast
Investigators may refer to the Investigator Brochure for additional information. 
Patients who require use of concomitant medications metabolized by the CYP1A2, 2D6, 2C19, 3A4 
and 2C9 enzymes should be monitored, as per drug product label, as use of BBI-608 can inhibit the 
abovementioned CYP enzymes leading to increased drug concentrations of the enzyme metabolites.
In addition, nab-paclitaxel is metabolized by CYP2C8 and CYP3A4; caution should be exercised when 
administering with drugs which are CYP2C8 or CYP3A4 inducers or inhibitors, e.g. amiodarone, 
cyclosporine, grapefruit juice, simvastatin etc.
7.8.2
Non-Permitted Treatments
Concurrent chemotherapy, hormonal therapy (except corticosteroids), immunotherapy, biologic 
therapy OR other experimental agents should not be given to study patients while on protocol 
treatment.
7.9
DURATION OF THERAPY
Patients may continue to receive protocol therapy as long as they have not experienced any adverse 
events requiring permanent discontinuation of protocol treatment, have not demonstrated disease 
progression based on RECIST 1.1 criteria, it is believed to be in the patient’s best interest by the 
investigator and patient, or until February 28th, 2020, whichever occurs first. For details concerning 
toxicity, please consult sections 7.3, 7.4 and 7.5. For a complete list of general criteria for stopping 
study treatment, please see section 11.0.  
Following disease progression based on RECIST 1.1 criteria, patients will permanently discontinue 
treatment with nab-paclitaxel and gemcitabine, but may continue BBI-608 treatment with the 
Sponsor’s approval for as long as in the opinion of the investigator and patient that it is believed to be 
in the patient’s best interest and with the patient’s informed consent, until February 28th, 2020 or the 
following requirements are met: 
1.
Patient does not demonstrate a clinically apparent decline in performance status.
2.
Patient does not demonstrate clinically significant worsening of disease related symptoms.
3.
Patient does not have any new radiographic findings to warrant emergent intervention to
prevent morbidity (for example, impending cord compression). 
4.
Patient demonstrates a tolerable toxicity profile with BBI-608 administration.

Treatment compliance for nab-paclitaxel with gemcitabine is defined as the ratio, expressed as a 
percentage, of the amount of each of the component drugs administered to a patient (milligrams/m2)
over the course of a time interval to amount of the component IV drug intended to be administered
over that same time interval. 
Treatment compliance in all study arms will be monitored by drug accountability, as well as the 
monitoring of patient-reported compliance.

After permanent protocol treatment discontinuation of nab-paclitaxel and gemcitabine and BBI-608, Physical 
examination, vital signs, ECOG status and subsequent cancer treatment will be recorded at the first regularly scheduled 4 
week assessment at which the patient has been off study therapy for a minimum of 28 days (+/- 3 days). Subsequent cancer 
treatment will be captured until end of study. 
2
Adverse events related to protocol treatment will be recorded and graded according to the NCI Common Terminology 
Criteria for Adverse Events version 4.0 (see Appendix IV). Adverse events relevant to cancer or to subsequent cancer 
treatments will not be captured. Attribution of adverse events will continue to be recorded following treatment 
discontinuation.
3
Serious adverse events will be recorded and graded according to the NCI Common Terminology Criteria for Adverse 
Events version 4.0 (see Appendix IV). 
4
Post permanent study treatment discontinuation, overall survival status will be monitored on a monthly basis for 6 months 
and then every 3 months thereafter until death, the study closes or 3 years have elapsed since subject discontinuation from 
treatment. In the event that patient is unable to attend clinic, post-progression follow-up may be by means of telephone 
contact.

in section 9.0). If a patient discontinues protocol treatment for a reason other than objective progression, every effort 
should be made to obtain this assessment on the same schedule until progression is observed. It is recommended that 
subsequent therapy not be instituted until disease progression is documented. If a patient starts a new anti-cancer therapy 
prior to disease progression, then repeat imaging and tumor response assessments should be discontinued.

CRITERIA FOR MEASUREMENT OF STUDY ENDPOINTS
9.1
DEFINITIONS
9.1.1
Evaluable for Adverse Events
All patients who have received at least one dose of study drug (BBI-608 or Nab-Paclitaxel or 
Gemcitabine) will be evaluable for adverse events from the time of their first dose.
9.1.2
Evaluable for OS
All randomized patients will be included in the analysis of OS, which is defined as the time interval 
between the date of randomization and the date of death from any cause. Patients who are still alive at 
the time of the final analysis, or who have become lost to follow-up will be censored at their last date 
known to be alive.  
9.1.3
Evaluable for PFS
All randomized patients will be included in the analysis of PFS, which is defined as the time interval 
between the date of randomization and the date of objective disease progression or death, whichever 
comes first. If neither event has been observed, then the patient will be censored at the date of the last 
tumor assessment.
Disease progression is defined as objective progression per RECIST 1.1 (Eisenhauer, 2009). It is 
required to perform, whenever possible, a radiological confirmation of the clinical suspicion of tumor 
progression. In the situation where there is clinical suspicion of progression but objective progression 
cannot be determined per RECIST 1.1, disease is defined as clinical deterioration without objective 
evidence of progression. 
The date of disease progression is defined as the date when the criteria for objective progression are 
first met. 
9.1.4
Evaluable for DCR
Patients who have measurable disease by RECIST 1.1 at randomization will be included in the analysis 
of DCR which is defined as a composite of Stable Disease, Partial Response and Complete Response 
as classified according to the definitions set out below (Eisenhauer, 2009). For patients who 
discontinue protocol therapy prior to their first objective assessment of response, it is imperative that 
an objective response assessment be undertaken as close to the protocol specified schedule as possible.
9.1.5
Evaluable for ORR
Patients with measurable disease by RECIST 1.1 at randomization will be included in the analysis of 
ORR which is defined as a composite of Partial Response and Complete Response as classified 
according to the definitions set out below (Eisenhauer, 2009). For patients who discontinue protocol 
therapy prior to their first objective assessment of response, it is imperative that an objective response 
assessment be undertaken as close to the protocol specified schedule as possible.
9.1.6
Evaluable for QoL Assessment

CONFIDENTIAL
All patients who have completed the baseline quality of life questionnaire and at least one other QoL 
questionnaire are evaluable.
9.2
RESPONSE AND EVALUATION ENDPOINTS
Response and progression will be evaluated in this study using the revised international criteria (1.1) 
proposed by the RECIST committee. 
9.2.1
Measurable Disease
Measurable tumor lesions are defined as those that can be accurately measured in at least one 
dimension (longest diameter to be recorded) as > 20 mm with chest x-ray and as > 10 mm with CT 
scan, or clinical examination. Bone lesions are considered measurable only if assessed by CT scan and 
have an identifiable soft tissue component that meets these requirements (soft tissue component > 10 
mm by CT scan). Malignant lymph nodes must be > 15mm in the short axis to be considered 
measurable; only the short axis will be measured and followed. All tumor measurements must be 
recorded in millimeters (or decimal fractions of centimeters). Previously irradiated lesions are not 
considered measurable unless progression has been documented in the lesion. 
9.2.2
Non-Measurable Disease
All other lesions (or sites of disease), including small lesions are considered non-measurable disease. 
Bone lesions without a measurable soft tissue component, leptomeningeal disease, ascites, 
pleural/pericardial effusions, lymphangitis cutis/pulmonis, inflammatory breast disease, lymphangitic 
involvement of lung or skin and abdominal masses followed by clinical examination are all non-
measurable. Lesions in previously irradiated areas are non-measurable, unless progression has been 
demonstrated. 
9.2.3
Target Lesions
When more than one measurable tumor lesion is present at baseline all lesions up to a maximum of 5 
lesions total (and a maximum of 2 lesions per organ) representative of all involved organs should be 
identified as target lesions and will be recorded and measured at baseline. 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.
Note that pathological nodes must meet the criterion of a short axis of > 15 mm by CT scan and only 
the short axis of these nodes will contribute to the baseline sum. All other pathological nodes (those 
with short axis > 10 mm but < 15 mm) should be considered non-target lesions. Nodes that have a 
short axis < 10 mm are considered non-pathological and should not be recorded or followed (see 
10.2.4). At baseline, the sum of the target lesions (longest diameter of tumor lesions plus short axis of 
lymph nodes: overall maximum of 5) is to be recorded. 
After baseline, a value should be provided on the CRF for all identified target lesions for each 
assessment, even if very small. If extremely small and faint lesions cannot be accurately measured but 
are deemed to be present, a default value of 5 mm may be used. If lesions are too small to measure and 
indeed are believed to be absent, a default value of 0 mm may be used.
9.2.4
Non-Target Lesions


CanStem111P
Protocol Date: 2019-JUL-31
Amendment #5 
  
CONFIDENTIAL
41
CONFIDENTIAL
All non-measurable lesions (or sites of disease) plus any measurable lesions over and above those 
listed as target lesions are considered non-target lesions. Measurements are not required but these 
lesions should be noted at baseline and should be followed as “present” or “absent”.
9.2.5
Response 
All patients will have their BEST RESPONSE from the start of study treatment until the end of 
treatment classified as outlined below: 
Complete Response (CR): disappearance of target and non-target. Pathological lymph nodes must 
have short axis measures < 10 mm (Note: continue to record the measurement even if < 10 mm and 
considered CR). Residual lesions (other than nodes < 10 mm) thought to be non-malignant should be 
further investigated (by cytology specialized imaging or other techniques as appropriate for individual 
cases (Eisenhauer, 2009)) before CR can be accepted. 
Partial Response (PR): at least a 30% decrease in the sum of measures (longest diameter for tumor 
lesions and short axis measure for nodes) of target lesions, taking as reference the baseline sum of 
diameters. Non-target lesions must be non-PD. 
Stable Disease (SD): neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify 
for PD taking as reference the smallest sum of diameters on study.
Progressive Disease (PD): at least a 20% increase in the sum of diameters of measured lesions taking 
as references the smallest sum of diameters recorded on study (including baseline) AND an absolute 
increase of > 5mm. Appearance of new lesions will also constitute progressive disease (including 
lesions in previously unassessed areas). For patients with on-study tumor assessments with 
questionable findings of new lesions, such as cases where it is possible that the lesions were present at 
baseline imaging albeit less visible, the patient may continue treatment (if patient is clinically doing 
well) for an additional 4-8 weeks, until the next scan which will either confirm presence of a new 
lesion finding or exclude it. In exceptional circumstances, unequivocal progression of non-target 
disease may be accepted as evidence of disease progression, where the overall tumor burden has 
increased sufficiently to merit discontinuation of treatment or where the tumor burden appears to have 
increased by at least 73% in volume. Modest increases in the size of one or more non-target lesions 
are NOT considered unequivocal progression. If the evidence of PD is equivocal (target or non-target), 
treatment may continue until the next assessment, but if confirmed, the earlier date must be used.

treatment.
9.3
RESPONSE DURATION
Response duration will be measured from the time measurement criteria for CR/PR (whichever is first 
recorded) are first met until the first date that recurrent or progressive disease is objectively 
documented, taking as reference the smallest measurements recorded on study (including baseline).
9.4
STABLE DISEASE DURATION
Stable disease duration will be measured from the time of randomization until the criteria for 
progression are met, taking as reference the smallest sum on study (including baseline).
9.5
METHODS OF MEASUREMENT
The same method of assessment and the same technique should be used to characterize each identified 
and reported lesion at baseline and during follow-up. Assessments should be identified on a calendar 
schedule and should not be affected by delays in therapy. While on study, all lesions recorded at 
baseline should have their actual measurements recorded at each subsequent evaluation, even when 
very small (e.g. 2 mm). If it is the opinion of the radiologist that the lesion has likely disappeared, the 
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly seen but 
too small to measure, a default value of 5 mm should be assigned. For lesions which fragment/split 
add together the longest diameters of the fragmented portions; for lesions which coalesce, measure the 
maximal longest diameter for the “merged lesion”.
Additionally, for optimal tumor assessment scanning options are listed below in the decreasing order 
of preference:

9.5.1
Clinical Lesions 
Clinical lesions will only be considered measurable when they are superficial and > 10 mm as assessed 
using callipers (e.g. skin nodules). For the case of skin lesions, documentation by colour photography 
including a ruler to estimate the size of the lesion is recommended. If feasible, imaging is preferred.
9.5.2
Chest X-ray
Chest CT is preferred over chest X-ray, particularly when progression is an important endpoint, since 
CT is more sensitive than X-ray, particularly in identifying new lesions. However, lesions > 20 mm 
on chest X-ray may be considered measurable if they are clearly defined and surrounded by aerated 
lung.  
9.5.3
CT/MRI
CT is the best currently available and reproducible method to measure lesions selected for response 
assessment. This guideline has defined measurability of lesions on CT scan based on the assumption
that CT slice thickness is 5 mm or less. When CT scans have slice thickness greater than 5 mm, the 
minimum size for a measurable lesion should be twice the slice thickness. MRI is also acceptable in 
certain situations (e.g. for body scans). Other specialized imaging or other techniques may also be 
appropriate for individual case (Eisenhauer, 2009). For example, while PET scans are not considered 
adequate to measure lesions, PET-CT scans may be used providing that the measures are obtained 
from the CT scan and the CT scan is of identical diagnostic quality to a diagnostic CT (with IV and 
oral contrast). 
9.5.4
Ultrasound 
Ultrasound is not useful in assessment of lesion size and should not be used as a method of 
measurement. If new lesions are identified by ultrasound in the course of the study, confirmation by 
CT is advised.
9.5.5
Endoscopy/Laparoscopy 
The utilization of these techniques for objective tumor evaluation is not advised. However, they can 
be useful to confirm complete pathological response when biopsies are obtained or to determine 
relapse in trials where recurrence following complete response or surgical resection is an endpoint. 
9.5.6
Histology
These techniques can be used to differentiate between PR and CR in rare cases (for example, residual 
lesions in tumor types such as germ cell tumors, where known residual benign tumors can remain).
The cytological confirmation of the neoplastic origin of any effusion that appears or worsens during 
treatment when the measurable tumor has met criteria for response or stable disease is mandatory to 
differentiate between response or stable disease (an effusion may be a side effect of the treatment) and 
progressive disease.

SERIOUS ADVERSE EVENT REPORTING
The descriptions and grading scales found in the NCI Common Terminology Criteria for Adverse 
Events (CTCAE) will be utilized for Adverse Event (AE) and Serious Adverse Event (SAE) reporting 
(version can be found in Appendix IV).  
All appropriate treatment areas should have access to a copy of the CTCAE. A copy of the CTCAE 
can be downloaded from the CTEP web site: 
(http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm).
All serious adverse events (SAE) defined as per ICH guidelines (see below) and other adverse events 
must be recorded on case report forms. All SAEs must be reported to the Sponsor within 24 hours 
(Section 10.2).    
10.1
DEFINITION OF A PROTOCOL REPORTABLE SERIOUS ADVERSE EVENT
All serious adverse events must be reported in an expedited manner (see Section 10.2 for reporting 
instructions). These include events occurring from the time the patient signs informed consent until 30 
days after last protocol treatment administration. Determination of relationship between the event and 
study drug should be made by a qualified physician Investigator.  
A serious adverse event (SAE) is any adverse event that at any dose:

results in death;

is life-threatening;

requires inpatient hospitalization or prolongation of existing hospitalization (excluding 
hospital admissions for study drug administration); 

results in persistent or significant disability or incapacity;

is a congenital anomaly/birth defect.

is an important medical event. 
 
 
Note: clinically significant test results should be recorded on the AE CRF using the appropriate 
CTCAE description and grading scale. 
10.2
SERIOUS ADVERSE EVENT REPORTING INSTRUCTIONS
SAE reporting will commence following the signature of the informed consent and continue for 30
days following the last dose of BBI-608 and/or Nab-Paclitaxel and/or Gemcitabine. Any SAE 
occurring following patient signature of informed consent and prior to patient randomization must be 
submitted to the Sponsor/Sponsor Designee for review and confirmation of randomization eligibility
prior to patient randomization and/or study drug administration, even if the patient completely 
recovered from the SAE. Additionally, any SAE occurring at any time following administration of the 
final dose of protocol treatment that is suspected to be related to study treatment must be reported.
All SAEs must be reported using the SAE Report Form for this trial.

PROCEDURES IN CASE OF AN OVERDOSE
Use of BBI-608 in doses in excess of that specified in the protocol should be reported in the following 
manner: 
If an adverse event(s) is associated with (“results from”) the overdose of BBI-608, the overdose and 
adverse event are reported on the SAE Report Form, even if no other criteria for serious are met. The 
SAE Report Form should be submitted within 24 hours. The overdose should also be recorded on the 
relevant AE form in the eCRF using the term “accidental or intentional overdose with adverse effect.”
If the overdose of BBI-608 is not associated with an adverse event, the overdose is reported as a non-
serious AE, on the relevant AE form in the eCRF within 24 hours, using the event term “accidental or 
intentional overdose without adverse effect.” The Clinical Research Associate responsible for the 
investigational center should also be notified of the event within 24 hours. 
Investigators/site personnel are to consult the local, approved product labels for nab-paclitaxel with 
gemcitabine treatment regimen for guidance on the definition of an overdose of these agents as well 
as for guidance on reporting of any AE or SAE associated with overdose of either nab-paclitaxel or 
gemcitabine. Overdose of either nab-paclitaxel or gemcitabine should also be reported to the Sponsor 
in accordance with overdose reporting guidelines above. 
10.4
OTHER PROTOCOL REPORTABLE EVENTS – PREGNANCY/EXPOSURE REPORTING
WOCBP may be enrolled in this clinical trial. WOCBP are defined as women who have had a 
menstrual period during the last year and have not had a hysterectomy. Precautions are required to be 
taken to prevent pregnancy during the clinical trial when the research population includes WOCBP. 
This includes pregnancy testing, use of effective methods of birth control, and pregnancy as an 
exclusion factor. The trial sample informed consent form includes the potential for unidentified risks 
to the embryo/fetus. It also includes general information on pregnancy prevention and the required 
minimum period during which birth control must be utilized.  
10.4.1 Pregnancy Prevention
WOCBP and males who are enrolled in the trial must be informed of the requirement to use 
contraception as outlined in the eligibility criteria (Sections 4.1 and 4.2). Investigators are advised to 
inform the female partners of male participants when appropriate and compliant with local policy.  
A highly effective method of birth control is defined as those which result in a failure rate of <1% per 
year when used consistently and correctly. 
10.4.2 Pregnancy Occurring in WOCBP Exposed to Study Agent 
Any female participant who becomes pregnant during the course of the trial should be instructed to

stop taking study medication immediately.
The Investigator should provide counselling and discuss the risks and possible side effects to the 
embryo/fetus from BBI-608 and nab-paclitaxel with gemcitabine. Monitoring should continue until 
conclusion of the pregnancy. The same should occur for female partners of a male participant, or any 
female exposed to BBI-608 when appropriate and compliant with local policy. 
10.4.3 Pregnancy/Exposure Reporting 
The Investigator is required to report to the sponsor any pregnancy where the embryo/fetus could have 
been exposed to BBI-608. This means pregnancies occurring in female participants, female partners 
of male participants, or females exposed through direct contact with the agent during their pregnancy 
(for example, environmental exposure involving direct contact with the agent). Pregnancies occurring 
until 30 days in female patients and until 90 days in partners of male patients, after the completion of 
BBI-608 must also be reported. Pregnancies occurring until 180 days in female patients and until 180 
days in partners of male patients, after the completion of nab-paclitaxel and/or gemcitabine must also 
be reported. 
The Investigator is required to inform the Sponsor within 24 hours of learning of the pregnancy using 
the SAE reporting form appropriate for the trial as indicated above. In the Adverse Event column 
please enter the following: “pregnancy, puerperium and perinatal conditions – other, specify” (fetal 
exposure). Please note that the patient identification number must correspond to the participant in the 
main trial. Specifically, in the case of pregnancy in the female partner of a male participant, the male 
participant’s patient identification number should be used for reporting purposes.  
The SAE form must be updated to reflect the outcome of the pregnancy. For example: 
y
“pregnancy, puerperium and perinatal conditions – other, specify” (normal live birth),
y
“pregnancy, puerperium and perinatal conditions – other, specify” (therapeutic abortion), or 
y
another term under "pregnancy, puerperium and perinatal conditions" as applicable. 
Information on the medical history of the parents that may relate to assessing any potential fetal 
outcomes is requested, as is information on the health of the newborn. The narrative section of the 
SAE form should be used to communicate all relevant information pertaining to the pregnancy. 
10.5
RESPONSIBILITY FOR REPORTING SERIOUS ADVERSE EVENTS TO REGULATORY 
AGENCIES
Boston Biomedical, or the delegated CRO, will provide expedited reports of SAEs to FDA and other 
applicable regulatory authorities, for those events which meet regulatory requirements for expedited 
reporting, i.e. events which are BOTH serious AND unexpected, AND which are related to treatment
BBI-608 (suspected unexpected serious adverse reaction [SUSAR]):
y
Unexpected adverse events are those which are not consistent in either nature or severity with the 
reference safety information contained in the Investigator’s Brochure  
y
Adverse events considered related to protocol treatment are those events which have a 
reasonable possibility of being related to BBI-608. 
Boston Biomedical will determine which SAEs meet the criteria for regulatory reporting.

PROTOCOL TREATMENT DISCONTINUATION AND THERAPY AFTER STOPPING 
ALL STUDY TREATMENT
11.1
CRITERIA FOR DISCONTINUING PROTOCOL TREATMENT
Patients should stop protocol treatment in the following instances:
y
Progressive Disease (see section 9.2.5) 
y
Pregnancy
y
Intercurrent illness which would, in the judgement of the Investigator, affect assessments of 
clinical status to a significant degree, and require discontinuation of protocol therapy 
y
Unacceptable toxicity
y
Request by the patient
If a patient discontinues protocol treatment for objective progression on nab-paclitaxel and 
gemcitabine with BBI-608 (Arm 1), the patient together with their investigator, may elect to continue 
treatment with BBI-608 in monotherapy with the Sponsor’s approval, provided no discontinuation 
criterion involving BBI-608-related adverse events is met, it is believed to be in the patient’s best 
interest by the investigator and patient, and with the patient’s informed consent.
If a patient permanently discontinues protocol treatment for a reason other than objective progression, 
every effort should be made to obtain tumor evaluations on the same schedule until progression is 
observed. 
Efforts should be made to maintain the investigations schedule and continue follow-up, even if patients 
discontinue protocol treatment prematurely and/or no longer attend the participating institution.  
11.2
DURATION OF PROTOCOL TREATMENT 
Patients may continue to receive protocol treatment as long as they have not experienced any adverse 
events requiring permanent discontinuation of study medication and have not demonstrated disease 
progression based on RECIST criteria, if it is believed to be in the patient’s best interest or until 
February 28th, 2020, when the study is planned for completion, whichever occurs first.  
There will be no cross-over to BBI-608-containing study arm in combination with nab-paclitaxel and 
gemcitabine (Arm 1) from the nab-paclitaxel and gemcitabine only study arm (Arm 2) and vice versa. 
11.3
THERAPY AFTER PROTOCOL TREATMENT IS PERMANENTLY DISCONTINUED
Treatment after all protocol therapy has been permanently discontinued is at the discretion of the 
Investigator. Information on post-study anti-cancer treatment will be collected in this study.

TISSUE COLLECTION
Protocol-Mandated Correlative Studies: 
The submission of a representative diagnostic tumor tissue and of a blood sample for correlative studies 
defined in Section 13.6 (Correlative Studies) is mandatory for participation in this trial (although 
submission of the tissue does not have to occur prior to randomization). Where local center regulations 
prohibit submission of blocks of tumor tissue, two 2 mm cores of tumor from the block and 5-20
unstained slides of representative tumor tissue are requested. Where 2 mm cores of tumor from the 
block are unavailable, 5-20 unstained slides of representative tumor tissue are requested. Where no 
previously resected or biopsied tumor tissue exists, on the approval of the Sponsor/designated CRO, 
the patient may still be considered eligible for the study.
After patient consent, blood sample and paraffin tumor blocks will be the preferred tissue material to 
collect. If tumor blocks are unavailable, then two 2 mm cores of tumor from the block and 5-20 
specimen slides are preferred. If two 2 mm cores of tumor from the block are unavailable, 5-20 
specimen slides will be acceptable. If, at any time, the submitting hospital requires the block to be 
returned for medical or legal concerns, it will be returned by courier on request. 
Samples will be used for research purposes only and will not be sold. Patients will not be identified by 
name. The only identification of tissue will be by a patient study number assigned at the time of 
randomization to the trial. Material issued to researchers will be anonymous and only identified by a 
coded number. 
Testing for hereditary genetic defects predisposing to malignant disease will not be carried out without 
the expressed consent of the patient.  
All patients on whom a blood sample and/or diagnostic tumor block is collected will be aware of this 
retrieval and will have given their consent.

SPARSE PHARMACOKINETIC PLASMA SAMPLE COLLECTION – NAB-PACLITAXEL 
WITH GEMCITABINE AND BBI-608 (ARM 1 ONLY)  
Plasma samples for sparse pharmacokinetics (PK) analysis will be obtained from all patients 
randomized to nab-paclitaxel with gemcitabine and BBI-608 study arm (Arm 1) at the study visits 
occurring on Days 8 and 15 of Cycle 1, and Day 1 of Cycle 2 (corresponding to nab-paclitaxel with

gemcitabine infusion days). Patients randomized to nab-paclitaxel and gemcitabine arm alone (Arm 2) 
will not undergo collection of blood for sparse PK analysis.  
Day 8 (Cycle 1) Study Visit: 
The Day 8 (Cycle 1) visit should be scheduled prior to 10 AM. On the day of this visit, patients should 
be instructed to wait to take their first daily dose of BBI-608 until they arrive in clinic. After arrival in 
the clinic, but approximately 5 minutes prior to administration of the first daily dose of BBI-608, a 
plasma sample will be obtained. Nab-paclitaxel infusion will be started approximately 2 hours after 
BBI-608 administration. A second plasma sample will be obtained within 60-180 minutes after the 
start of nab-paclitaxel infusion. A third plasma sample will be obtained within 240-480 minutes after 
the start of nab-paclitaxel infusion.  
Day 15 (Cycle 1) Study Visit: 
The Day 15 (Cycle 1) visit should be scheduled prior to 10 AM. On the day of this visit, patients should 
be instructed to take their first daily dose of BBI-608 until they arrive in clinic. After arrival in the 
clinic, but approximately 5 minutes prior to administration of the first daily dose of BBI-608, a plasma 
sample will be obtained. Nab-paclitaxel infusion will be started approximately 2 hours after BBI-608 
administration. A second plasma sample will be obtained within 60-180 minutes after the start of nab-
paclitaxel infusion. A third plasma sample will be obtained within 240-480 minutes after the start of 
nab-paclitaxel infusion.  
Day 1 (Cycle 2) Study Visit: 
The Day 1 (Cycle 2) visit should be scheduled prior to 10 AM. On the day of this visit, patients should 
be instructed to wait to take their first daily dose of BBI-608 until they arrive in clinic. After arrival in 
the clinic, but approximately 5 minutes prior to administration of the first daily dose of BBI-608, a 
plasma sample will be obtained. Nab-paclitaxel infusion will be started approximately 2 hours after 
BBI-608 administration. A second plasma sample will be obtained within 60-180 minutes after the 
start of nab-paclitaxel infusion. A third plasma sample will be obtained within 240-480 minutes after 
the start of nab-paclitaxel infusion.  
For all days during which a plasma sample is obtained for PK analysis, the precise time of all doses of 
BBI-608 (on the day of sampling and the day prior), the precise time of the initiation of nab-paclitaxel 
and gemcitabine administration, and the precise time of all PK sampling must be captured. 
Samples will be processed, stored and shipped according to the instructions provided in the separate
Sparse PK sampling laboratory manual for this study.

STATISTICAL CONSIDERATIONS
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.  The SAP 
may modify the plans outlined in the protocol; however, any major modifications of the primary 
endpoint definition and/or its analysis will also be reflected in a protocol amendment. 
13.1
OBJECTIVES AND DESIGN 
The primary objective of this study is to assess the effect of orally administered BBI-608 plus weekly 
nab-paclitaxel with gemcitabine (Arm 1), in comparison to weekly nab-paclitaxel with gemcitabine
(Arm 2) on the Overall Survival (OS) in patients with metastatic PDAC. 
Key secondary objectives for this study include comparisons of PFS in the general population, DCR
in the general population and ORR in the general population. Other secondary objectives include
Adverse Events and Quality of Life Assessment in the general population between the two treatment 
arms.
This is a multi-center, prospective, open-label, randomized Phase III trial. Patients will be randomized 
to receive either BBI-608 plus weekly nab-paclitaxel with gemcitabine, or weekly nab-paclitaxel with 
gemcitabine in a 1:1 ratio and will be stratified by geographical region (North America/Western 
Europe/Australia vs. Japan/Korea vs. Rest of the World), ECOG performance status (ECOG 0 versus 
ECOG 1), and presence of liver metastases (yes versus no).
13.2
STUDY ENDPOINTS AND ANALYSIS
13.2.1 Primary Endpoint 
OS in the General Study Population 
Unless otherwise specified, all efficacy analyses will be based on the Primary Analysis Set, which 
includes all randomized patients. Patients will be analyzed as randomized. As a sensitivity analysis, 
the Per Protocol population will also be analyzed for key efficacy endpoints. 
Overall Survival in the general study population, the primary endpoint of this study, is defined as the 
time from randomization to death from any cause. Patients who are alive at the time of the final analysis 
or who have become lost to follow-up will be censored at their last date known to be alive. Patients 
will be analyzed in the arm to which they are randomized regardless of the treatment they received 
(intent-to-treat analysis). The survival experience of patients in both treatment groups will be 
summarized by the Kaplan-Meier method and compared primarily by a stratified log-rank test 
adjusting for stratification variables at randomization.  
Sensitivity analyses based on stratified Cox proportional hazards model will also be performed. These 
sensitivity analyses are not included in the multiplicity adjustment for secondary outcomes detailed 
below and, as such, do not control for type I error. Geographical region (North America/Western 
Europe/Australia vs. Japan/Korea vs. Rest of the World), ECOG performance status (ECOG 0 versus
ECOG 1), and presence of liver metastases (yes versus no) will be the stratification factors to define

the stratified Cox proportional hazards model.  
Subgroup analysis and the corresponding forest plot analysis may be performed using the stratification 
factors mentioned above as well as the following factors: 
x
Primary tumor location (head versus other)
x
Level of CA19-9 (normal versus <59 x ULN versus >59 x ULN)
x
Age (< 65 versus > 65)
x
Sex (male versus female)
x
Number of metastatic sites at baseline (1 versus > 2) 
x
Race (white, black, Asian, other)
x
Country (Canada, USA, Europe, others) 
13.2.2 Key Secondary Endpoints 
The following secondary outcomes will be assessed. 
PFS in the General Study Population 
PFS in the general study population is defined as the time from randomization to the first objective 
documentation of disease progression or death due to any cause. If a patient has not progressed or died 
at the time of final analysis, PFS will be censored on the date of the last tumor assessment. This 
includes patients who are lost to follow-up or have withdrawn consent.  
DCR in the General Study Population
DCR is defined as the proportion of patients with a documented complete response, partial response, 
and stable disease (CR + PR + SD) based on RECIST 1.1. The primary estimate of DCR will be based 
on patients with measurable disease by RECIST 1.1 at randomization.  
ORR in the General Study Population
ORR is defined as the proportion of patients with a documented complete response and partial response 
(CR + PR) based on RECIST 1.1. The primary estimate for ORR will be based on patients with 
measurable disease by RECIST 1.1 at randomization. 
13.2.3 Other Secondary Endpoints 
Safety Analysis
All patients who have received at least one dose of study drug will be included in the safety analysis. 
The incidence of adverse events will be summarized by type of adverse event and severity using the 
NCI Common Terminology Criteria for Adverse Events Version 4.0. A Fisher’s exact test may be used 
to compare adverse events between the two arms.
QoL Analysis 
The QoL of patients will be assessed using EORTC QLQ-30 while the patient remains on BBI-608 as 
per Section 8.1. The EORTC QLQ-30 is a self-administered cancer specific questionnaire with multi-
dimensional scales. It consists of both multi-item scales and single item measures, including five 
functional domains, a global quality of life domain, three symptom domains, and six single items. 
Scoring of the EORTC QLQ-30 data will be completed following the procedures recommended by the 


CanStem111P
Protocol Date: 2019-JUL-31
Amendment #5 
  
CONFIDENTIAL
54
CONFIDENTIAL
EORTC Study Group on Quality of Life. For each domain or single item measure a linear 
transformation will be applied to standardize the raw score to range between 0 and 100. The quality of 
life data will be analyzed to look for statistically and clinically significant differences between the 
BBI-608 plus nab-paclitaxel with gemcitabine versus nab-paclitaxel with gemcitabine groups. 
Questionnaire compliance rates will be ascertained for each group at each measurement time point. 
Mean baseline scores for each subscale and summary scores will be calculated.
The endpoints in QoL analysis are the mean EORTC QLQ-C30 QoL change scores from baseline at 
time 2 (~8 weeks from Cycle 1 Day 1) and time 4 (~16 weeks from Cycle 1 Day 1) for the physical 
function and global health status/quality of life subscale scores. Wilcoxon tests will be used to compare 
the difference at each of these two time points between two treatment arms for each of these two 
subscales. The proportion of patients in either arm with at least a minimum of 10 unit(s) deterioration 
in change scores at both 8 and 16 weeks from Cycle 1 Day 1 will be compared by means of Fisher’s 
exact test.
13.2.4 Exploratory Endpoints 
OS in the Predefined Biomarker-positive Population
OS in the general predefined biomarker-positive population is defined as the time from randomization 
to death due to any cause. If a patient has not died at the time of final analysis, OS will be censored on 
the date of the last follow up assessment. This includes patients who are lost to follow-up or have 
withdrawn consent.  
PFS in the Predefined Biomarker-positive Population
PFS in the predefined biomarker-positive population is defined as the time from randomization to the 
first objective documentation of disease progression or death due to any cause. If a patient has not 
progressed or died at the time of final analysis, PFS will be censored on the date of the last tumor 
assessment. This includes patients who are lost to follow-up or have withdrawn consent.  
ORR and DCR in the Predefined Biomarker-positive Population
ORR in the predefined biomarker-positive population is defined as the proportion of patients with a 
documented complete response and partial response (CR + PR) based on RECIST 1.1. The primary 
estimate for ORR will be based on patients with measurable disease by RECIST 1.1 at randomization. 
DCR in the predefined biomarker-positive population is defined as the proportion of patients with a 
documented complete response, partial response, and stable disease (CR + PR + SD) based on RECIST 
1.1. The primary estimate of DCR will be based on patients with measurable disease by RECIST 1.1 
at randomization.  
13.3
SAMPLE SIZE AND DURATION OF STUDY
The primary study endpoint for all patients on the study is OS.  
The study is designed to have a power of 90% and a one-sided alpha of 2.5% to detect a 20% reduction 
in the continuous risk of death (HR 0.80, which corresponds to an increase of median survival from 
8.5 to 10.63 months) in the Intention to Treat (ITT) general study population. The 864th event will 
trigger the final analysis. It is estimated that 864 events will be required to detect a 20% reduction in 
the risk of death which would be observed by randomizing 1132 patients over 24 months with patient 
follow up for an additional 12 months, for total study duration of 36 months. It is anticipated that up 
to 5% dropout rate will occur for the entire study.

Amendment #5 
  
CONFIDENTIAL
55
CONFIDENTIAL
The overall power of the study will be approximately 90% after the multiplicity control procedure is 
considered.
When the required number of events for the primary endpoint has been reached, all randomized 
patients still alive will continue study follow up through to their deaths.  
13.4
SAFETY MONITORING
Adverse events will be monitored on an on-going basis by central review. 
13.5
INTERIM ANALYSIS
Prior to this amendment, there was one interim analysis presented to the independent DSMB. 
Additionally, DSMB reviewed safety data during conduct of the study. The role and responsibility of 
the DSMB are defined in a separate Charter.
The interim analysis involved a stratified log-rank test. Nominal p-values were based on the Lan-
DeMets error spending function using an O’Brien-Fleming stopping boundary in order to preserve the 
overall one-sided alpha level of 0.025. 
The interim analysis was performed when approximately 432 deaths (50% of the required events) were
observed.  The interim analysis was for futility only, with the futility boundary set at HR > 1. Safety 
data and primary analysis based on approximately 432 events were presented to the DSMB on June 
24th, 2019. The DSMB reviewed the results on July 1st, 2019. Based on the recommendation of the 
DSMB, the Sponsor informed investigators on July 2nd, 2019 that the study would be discontinued due 
to futility. For patients enrolled to Arm 1, the Sponsor advised that patients stop treatment with BBI-
608 but given that no safety concerns were identified by the DSMB, in cases in which a patient appears 
to be deriving benefit from BBI-608 in the opinion of the investigator and with the patient’s informed 
consent, continuation of protocol therapy was permitted. Patients enrolled to Arm 2 were given the 
option to continue receiving standard of care therapy within the study.  
Patients may continue to receive protocol therapy until a discontinuation criterion is met, if believed 
to be in the patient’s best interest by the investigator and patient, and with the patient’s informed 
consent, or until February 28th, 2020, whichever occurs first. 
At study completion, analysis will be conducted for primary endpoint of OS as outlined in Section 13. 
Additionally, all secondary and exploratory analyses will be performed as outlined in the protocol.  
13.6
CORRELATIVE STUDIES
The correlative science component of the CanStem111P trial will include tumor and blood based 
assays to identify biomarkers of benefit from BBI-608 therapy, as well as biomarkers of BBI-608 
resistance. The purpose of these studies is to explore the possible relationship between biomarkers and 
disease response. The research aims to validate molecular markers such as genes (DNA) and gene 
products (mRNA or proteins), with measurements of their sequence, post translation modifications or

degree of expression, that can guide the use of appropriate therapeutic treatment regimens. The 
ultimate goal of identifying molecular markers is to improve subject responses and other measures of 
clinical benefit by matching an individual subject’s tumor diagnostic profile with an anticancer agent 
that has demonstrated a therapeutic advantage in subjects with a similar diagnostic profile. If such a 
marker can be identified, the samples and results may also aid in the development of diagnostic 
devices.
Using data from this and other trials, the relationship between a number of molecular markers 
DVVRFLDWHGZLWKWKH67$7ȕ-catenin and other related pathways, and the clinical outcomes with BBI-
608 therapy may be explored. Multiple molecular markers in a paraffin-embedded tumor tissue sample 
can be determined by analyzing RNA and protein in the tissue sample. 
In addition to analysis of potential biomarkers of benefit from BBI-608 therapy, an analysis of markers 
of resistance to BBI-608 will be conducted using blood samples drawn at baseline as well at 4 weeks 
post initiation of therapy. This analysis may involve SNPs, CYPS, and metabolomics.
Paraffin-embedded tumor specimens, or cores (two 2 mm cores of tumor from the block) and 5-20 
unstained slides obtained from paraffin embedded specimens will be required. Where it is not possible 
to obtain two 2 mm cores of tumor from the block, 5-20 unstained slides of representative tumor tissue 
are also acceptable. Patients who do not have available archival tissue may enroll on the study with 
permission of the Sponsor/CRO.
Blood samples will be collected prior to dosing with BBI-608 and then at week 4 while on BBI-608 in 
combination with nab-paclitaxel and gemcitabine. 
The following analysis will be performed to investigate the relationship between endpoints and 
biomarker levels (e.g. phospho-STAT3, etc): 
For each biomarker, Cox Proportional Hazards model will be used to model the relationship between 
Overall Survival, Progression-Free Survival and duration of response with baseline value of the 
biomarker. The model will also include assigned treatment, interaction between treatment and 
biomarker, and will be stratified by baseline ECOG performance status. 
For biomarkers with post-baseline measurements, similar analysis will be done with change from 
baseline of a biomarker as a covariate, for both time points. An additional model that includes 
prognostic factors may be investigated. 
The relationship between the endpoint and binary biomarkers (e.g. baseline phospho-STAT3 status, ß-
catenin, etc) will be also examined using the log-rank test, stratified by treatment and baseline ECOG 
performance status. Subgroup analysis by the status of the binary biomarker may also be performed. 
The Kaplan-Meier method will be used to describe overall survival, progression-free survival and 
duration of response by the status of the biomarker (e.g. phospho-STAT3-high vs. phospho-STAT3-
low) and by treatment group. 
The relationships between the binary response variable (e.g. objective response, DCR) with baseline 
values of biomarkers as well as with their change from baseline and at week 4 time point during 
treatment with nab-paclitaxel and gemcitabine with or without BBI-608 will be investigated using 
logistic regression that includes assigned treatment and biomarker value and treatment-by-biomarker 
interaction, stratified by baseline ECOG performance status. An additional model that includes 
prognostic factors may be investigated. The relationship between response and binary biomarkers (e.g.

baseline phospho-STAT3 status or STAT3 status) will also be examined using the CMH test, stratified 
by treatment and baseline ECOG performance status. Subgroup analysis by the status of the binary 
biomarker may also be performed. 
Exploratory analyses, in addition to those described in this section, such as alternative modeling 
approaches and analyses of other biomarkers are expected and may be performed. All analyses 
described in this section are based on availability of data.
13.7
SPARSE PHARMACOKINETIC ANALYSIS
Exploratory analyses will be performed on the bioanalytic data obtained from sparse plasma sampling 
in order to characterize the population pharmacokinetics of BBI-608. Demographic and 
pathophysiologic factors that affect plasma concentration of BBI-608 and nab-paclitaxel with 
gemcitabine in this population of patients with metastatic PDAC will be examined. The exposure-
response relationship between clinical and safety endpoints and BBI-608/nab-paclitaxel with 
gemcitabine exposure will also be examined.

ETHICAL, REGULATORY AND ADMINISTRATIVE ISSUES
16.1
REGULATORY CONSIDERATIONS
All institutions must conduct this trial in accordance with International Conference on Harmonization-
Good Clinical Practice (ICH-GCP) Guidelines. 
The conduct of this trial must comply with local laws and national regulations [e.g. in the United States 
of America with applicable US FDA Regulations; in Canada with Division 5 of the Canadian 
Regulations Respecting Food and Drugs (Food and Drugs Act)] relevant to the use of new therapeutic 
agents in the country of conduct. 
16.2
INCLUSIVITY IN RESEARCH
Individuals must not be excluded from participation in clinical trials on the basis of attributes such as 
culture, religion, race, national or ethnic origin, colour, mental or physical disability (except 
incapacity), sexual orientation, sex/gender, occupation, ethnicity, income, or criminal record, unless 
there is a valid reason (i.e. safety) for the exclusion.  
In accordance with the Declaration of Helsinki and the Tri-Council Policy Statement (TCPS), 
vulnerable persons or groups will not be automatically excluded from a clinical trial (except for 
incompetent persons) if participation in the trial may benefit the patient or a group to which the person 
belongs.  
However, extra protections may be necessary for vulnerable persons or groups. It is the responsibility 
of the local Investigator and Institutional Review Board (IRB) to ensure that appropriate mechanisms 
are in place to protect vulnerable persons/groups. In accordance with TCPS, researchers and IRB 
should provide special protections for those who are vulnerable to abuse, exploitation or 
discrimination. As vulnerable populations may be susceptible to coercion or undue influence, it is 
especially important that informed consent be obtained appropriately.  
Centers are expected to ensure compliance with local IRB or institutional policy regarding 
participation of vulnerable persons/groups. It is the center’s responsibility to ensure compliance with 
all local SOPs. 
Persons who cannot give informed consent (i.e. mentally incompetent persons, or those physically 
incapacitated such as comatose persons) are not to be recruited to this study. It is the responsibility of 
the local Investigator to determine the subject’s competency, in accordance with applicable local 
policies and in conjunction with the local IRB (if applicable). 
Subjects who were competent at the time of enrollment in the clinical trial but become incompetent 
during their participation do not automatically have to be removed from the study. When re-consent 
of the patient is required, Investigators must follow applicable local policies when determining if it is 
acceptable for a substitute decision maker to be used. The Sponsor will accept re-consent from a 
substitute decision maker. If this patient subsequently regains capacity, the patient should be re-
consented as a condition of continuing participation.

16.3
OBTAINING INFORMED CONSENT
Informed consent will be obtained for each participant/potential participant in this trial, in accordance 
with ICH-GCP section 4.8. The center is responsible for ensuring that all local policies are followed.
Additionally, in accordance with GCP 4.8.2, the Sponsor may require that participants/potential 
participants be informed of any new information may impact a participant’s/potential participant’s 
willingness to participate in the study. 
Based upon applicable guidelines and regulations (Declaration of Helsinki, ICH-GCP), a participating 
Investigator (as defined on the participants list) is ultimately responsible, in terms of liability and 
compliance, for ensuring informed consent has been appropriately obtained. The Sponsor recognizes 
that in many centers other personnel (as designated on the participants list) also play an important role 
in this process. In accordance with GCP 4.8.5, it is acceptable for the Principal Investigator to delegate 
the responsibility for conducting the consent discussion. 
The Sponsor requires that each participant sign a consent form prior to their enrolment in the study to 
document his/her willingness to take part. The Sponsor may also require, as indicated above, that 
participants/potential participants be informed of new information if it becomes available during the 
course of the study. In conjunction with GCP 4.8.2, the communication of this information should be 
documented. 
The Sponsor allows the use of translators in obtaining informed consent. Provision of translators is the 
responsibility of the local center. Centers should follow applicable local policies when procuring or 
using a translator for the purpose of obtaining informed consent to participate in a clinical trial. 
In accordance with ICH-GCP 4.8.9, if a subject is unable to read, then informed consent may be 
obtained by having the consent form read and explained to the subject. This process must be thoroughly 
documented. 
16.3.1 Obtaining Consent for Pregnancy/Exposure Reporting 
Information from and/or about the subject (i.e. the pregnant female, the newborn infant, male partner) 
should not be collected about or from them unless or until they are a willing participant in the research. 
The rights and protections offered to participants in research apply and consent must be obtained prior 
to collecting any information about or from them. If the pregnant female is not a participant in the 
main trial, consent should be obtained via use of the exposure/pregnancy follow-up consent form. 
In the case of information collected about a newborn, consent should be provided by the legal 
guardian. In cases where the legal guardian is the participant in the main trial, consent is obtained 
via the main consent. If the legal guardian is not the trial participant, consent should be obtained via 
the exposure/pregnancy follow-up consent.  
Participants will not be withdrawn from the main trial as a result of refusing or withdrawing permission 
to provide information related to the pregnancy/exposure. Similarly, male participants will not be 
withdrawn from the main study should their partner refuse/withdraw permission.

16.4
DISCONTINUATION OF THE TRIAL
The study is planned for completion on February 28th, 2020, at which time the Sponsor will cease 
provision of protocol treatment.
If this trial is discontinued for any reason by the Sponsor prior to February 28th, 2020, all centers will 
be notified in writing of the discontinuance and the reason(s) why. If the reason(s) for discontinuance 
involve any potential risks to the health of patients participating on the trial or other persons, the 
Sponsor will provide this information to centers as well.
If this trial is discontinued at any time by the center (prior to closure of the trial by the Sponsor), it is 
the responsibility of the Principal Investigator to notify the Sponsor of the discontinuation and the 
reason(s) why.  
Whether the trial is discontinued by the Sponsor or locally by the center, it is the responsibility of the 
Principal Investigator to notify the local Institutional Review Board and all clinical trials subjects of 
the discontinuance and any potential risks to the subjects or other persons.
Following trial closure after demonstrating overall survival benefit, and until the time that BBI-608 is 
commercially available, all patients randomized on the trial may have an opportunity to receive 
treatment with BBI-608; provided, that the Principal Investigator has determined that such continued 
treatment would be in the best interest of the patient, and subject to approval by the applicable 
regulatory authorities. This will be done via a new, open label extension study, or in another manner 
as determined by the Sponsor, requiring additional regulatory approval. 
16.5
RETENTION OF PATIENT RECORDS AND STUDY FILES
All essential documents must be maintained in accordance with ICH-GCP. 
The Principal Investigator must ensure compliance with GCP Guideline from every person involved 
in the conduct of the clinical trial at the site. 
Essential documents must be retained for 25 years following the completion of the trial at the center
(25 years post final analysis, last data collected, or closure notification to IRB, whichever is later), or 
until notified by the Sponsor that documents no longer need to be retained. 
In accordance with GCP 4.9.7, upon request by the monitor, auditor, IRB or regulatory authority, the 
Investigator/institution must make all required trial-related records available for direct access. 
The Sponsor will inform the Investigator/Institution as to when the essential documents no longer need 
to be retained. 
16.6
ON-SITE MONITORING/AUDITING
In addition to the routine review of case report forms and supporting documents sent to the central 
office, site monitoring will be conducted at participating centers in the course of the study as part of 
the overall quality assurance programme. The monitors/auditors will require access to patient medical 
records to verify the data, as well as pharmacy, essential document binders, standard operating

Hematology should be done within 72 hours prior to nab-paclitaxel + gemcitabine administration. Laboratory testing 
performed as part of standard of care prior to patient signature of the informed consent for the study will be acceptable as 
baseline labwork as long as testing is performed < 14 days prior to randomization.
10 Laboratory investigations should be performed within 72 hours prior to Day 1 of each Cycle of protocol treatment. Laboratory 
testing performed as part of standard of care prior to patient signature of the informed consent for the study will be acceptable 
as baseline labwork as long as testing is performed < 14 days prior to randomization. Total bilirubin will need to be repeated 
at <72 hours prior to randomization only for patients with Baseline total bilirubin >1 and <1.5 x ULN.
11 Standard tumor measurement procedures will be followed to assess response to therapy. The same method of assessment and 
the same technique should be used to identify and report each lesion at baseline and at reassessment during treatment. Tumor 
evaluations will continue until progressive disease is documented. For patients who remain on protocol therapy after objective 
disease progression has been documented, no further imaging assessments are mandated, but where these occur as a 
component of care, tumor measurements and assessment must be reported. Tumor assessments should be obtained within +/- 
5 days of protocol specified schedule. Qualifying scans performed as part of standard of care prior to patient signature of the 
study informed consent will be acceptable as baseline scanning as long as scanning is performed < 14 days prior to 
randomization.
12 Sample will be collected 4 weeks after Day 1 Cycle 1 and will not be performed beyond Cycle 2. A sample will be collected 
following protocol treatment discontinuation if discontinuation occurs prior to 4 weeks of therapy.
13 To be completed in clinic. Questionnaires should be completed at baseline and at 4, 8, 12, 16 and 24 weeks from Cycle 1 Day 
1 for as long as patient remains on protocol therapy or until deterioration to ECOG PS 4 or hospitalization for end of life care.
14 EORTC QLQ-C30 questionnaire will be collected in the post-protocol discontinuation period only if the patient discontinues 
protocol treatment prior to 24 weeks of therapy and has an ECOG PS of less than 4 and has not been hospitalized for end of 
life care.
15 BBI-608 administration will begin 2 days prior to the nab-paclitaxel+gemcitabine infusion on Day 1 of Cycle 1. These two 
days are referred to as Run-in Day and Run-in Day 2. Run-in Day 1 should occur within 2 calendar days of patient 
randomization. The run-in period may be extended by up to 3 additional calendar days.
16 Patients continuing on BBI-608 monotherapy post disease progression on nab-paclitaxel and gemcitabine will maintain the 
same schedule of events, except no longer have visits or bloodwork or AE assessment on Day 8 or Day 15 of the cycle 
following treatment discontinuation of nab-paclitaxel and gemcitabine. 
17 Nab-paclitaxel with gemcitabine administration should proceed according to institutional standard practice (with respect to 
pre-treatment laboratory evaluation, clinical assessment, pre-medication, and monitoring during and after infusion).
18 Subsequent cancer treatment will be captured until end of study.
19 After the first visit at which the patient has been off protocol treatment (BBI-608 and nab-paclitaxel with gemcitabine) for 4 
weeks, monitored on a monthly basis for 6 months and then every 3 months thereafter until death, the study closes or 3 years 
have elapsed since subject discontinuation from treatment. In the event that patient is unable to attend clinic, post-progression 
follow-up may be by means of telephone contact.

APPENDIX V - QUALITY OF LIFE ASSESSMENT
Introduction 
The assumption that control of symptoms will automatically improve quality of life is probably true but hasn't 
yet been tested, especially in determining how certain symptoms may or may not affect quality of life. Current 
literature reveals interesting things; two in particular are:
x additional and useful information may be obtained from quality of life measurements
x a growing consensus that the goal of medical care today for most patients is the preservation of function 
and well-being in everyday life
We have reached the stage where the collection of information about psychological distress, social disruption, 
emotional trauma and painful side-effects is not only necessary but a routine component in many protocols. 
Quality of life data can be used in a variety of ways:
x
to try to achieve the best possible outcome for patients
x
to evaluate the extent of change in the quality of life of an individual or group across time
x
to evaluate new treatments and technologies
x
to support approval of new drug applications 
x
to try to provide the best value for health care dollars 
x
to compare costs and benefits of various financial and organizational aspects of health care services
In the future, approval of not only drugs but also new therapies or methods of delivery will most likely be 
based on a combination of quality of life, survival, response, and adverse event data.
Instructions for Administration of a Quality of Life Questionnaire.  
The instructions below are intended as a guide for the administration of the Quality of Life questionnaire. 
1. Preamble
Quality of life data are collected for research purposes, and will usually not be used for the patient’s individual 
medical care. The assessment is in the form of a self-report questionnaire. Therefore, it must be completed by 
the patient only, without translation, coaching or suggestions as to the "correct" answer by relatives or health 
care personnel.
The usual scheduled times to obtain the questionnaires are as follows: 
x
pre-randomization or pre-registration (baseline)
x
during treatment 
x
during follow-up 
The information provided by the patient in the completed questionnaire is confidential and should not be 
discussed with or shown to anyone who is NOT mentioned in the consent form signed by the patient. 
If a particular question has not been answered, please document the reason(s) in the appropriate space on the 


CanStem111P
Protocol Date: 2019-JUL-31
Amendment #5 
  
CONFIDENTIAL
75
CONFIDENTIAL
questionnaire. If the whole questionnaire has not been completed, please document the reason(s) on the 
appropriate case report forms.
2. Pre-Treatment Assessment
It should be explained to the patient that the purpose of the questionnaire is to assess the impact of treatment 
on different areas of the patient's life, e.g.: psychological distress, social disruption, side-effects, et cetera.
Study staff should collect the questionnaire as soon as it has been completed, check to see that each question 
has been answered and gently remind the patient to answer any inadvertently omitted questions. If a patient 
states that s/he prefers not to answer some questions and gives a reason(s), the reason(s) should be noted on 
the questionnaire. If a specific reason is not given, this also should be noted on the questionnaire. 
3. Assessments During Treatment
The quality of life questionnaire should be given to the patient before being seen by the doctor, and prior to 
treatment on the day of treatment, as required by the schedule in the protocol. If the patient does not have a 
doctor visit scheduled, or if it was not possible for the patient to complete the questionnaire before being seen 
by the doctor, s/he should still complete the questionnaire prior to treatment.
4. Assessments During Follow-up 
The quality of life questionnaire should be given to the patient before being seen by the doctor, for as long as 
the patient continues on Protocol therapy, as required by the schedule at approximately: 
4, 8, 12, 16 and 24 weeks or until deterioration to ECOG PS 4 or hospitalization for end of life care  
the first regularly scheduled 4 week assessment at which the patient has been off study therapy for a minimum 
of 28 days (+/- 3 days) if study therapy discontinuation occurred prior to 24 weeks and until deterioration to 
ECOG PS 4 or hospitalization for end of life care 
A patient may, on occasion, be reluctant to complete the questionnaire because they feel unwell. In that case, 
you may express sympathy that things are below par, but state that this is exactly the information we require 
if we are to understand more about how quality of life is affected. You may also remind them that it takes only 
a few minutes to complete.
It defeats the whole purpose of the assessment if it is delayed until the patient feels better!
5. What If . . .
The patient should complete the questionnaires at the clinic. The exception is that the design of some trials 
may require the patient to take the questionnaire home with them after leaving the clinic, and complete it on 
the specific day, because a return visit to the clinic is not scheduled.
There may be circumstances when the patient does not complete the questionnaire as required in the clinic. 
Three situations are described below. In these cases, it is beneficial if quality of life data can still be collected.
A. The patient leaves the clinic before the questionnaire could be administered, or someone forgets to give the 
questionnaire to the patient.  
Contact the patient by phone informing him or her that the questionnaire was not completed. Ask the patient 
if s/he is willing to complete one:

Protocol Date: 2019-JUL-31
Amendment #5 
  
CONFIDENTIAL
76
CONFIDENTIAL
If yes, mail a blank questionnaire to the patient, and make arrangements for return of the questionnaire in a 
timely fashion. Record the date it was mailed and the date received on the questionnaire.
If this is not feasible, then ask the patient if s/he is willing to complete a questionnaire over the phone. If the 
patient agrees, read out the questions and range of possibilities, and record the answers. Make a note on the 
questionnaire that the questionnaire was completed over the phone. 
If no, note the reason why the questionnaire was not completed on the appropriate case report form.
B. The patient goes on an extended vacation for several months and won't attend the clinic for regular visit(s).
Ensure that the patient has a supply of questionnaires, with instructions about when to complete them, and how 
to return them. If it is known beforehand, give the patient blank questionnaires at the last clinic visit; if the 
extended absence is not known in advance, mail the blank questionnaires to the patient. Written instructions 
may help ensure that the patient stays on schedule as much as possible.  
C. The patient does not want to complete the questionnaire in clinic. 
Should the patient not wish to answer the questionnaire in the clinic but insists on taking it home, and failing 
to comply with the patient's wishes is likely to result in the questionnaire not being completed at all, then the 
patient may take the questionnaire home with instructions that it is to be completed the same day. When the 
questionnaire is returned, the date on which the questionnaire was completed should be noted and a comment 
made on the questionnaire as to why the patient took it away from the clinic before completion.

1. AMENDMENTS FROM PREVIOUS VERSION(S)  
This is the version 5.0 of the statistical analysis plan, based on the CanStem111P protocol 
amendment dated July 31, 2019. The major changes in this amendment include changing 
Boston Biomedical Inc to Sumitomo Dainippon Pharma Oncology, Inc, changing BBI-608
to napabucasin, adding language after futility boundary was met during first interim 
analysis, deleting the Per Protocol Analysis Set and the PD/Biomarker Analysis Set, editing 
the methods for handling missing data section, deleting country subgroup analysis, editing 
the baseline assessment window from 14 days to 28 days, adding censoring rules for time 
to event analysis of New Anti-cancer therapy, editing the dose intensity section, editing the 
Dose Changes section, editing the Adverse Events of Clinical Relevance section to 
Clustered TEAEs and the SMQs and sponsor derived terms associated with the analysis, 
adding pSTAT3 unknown to the biomarker analysis, editing the Primary and Secondary 
analyses from stratified for subgroup analyses to unstratified, removing PFS sensitivity 
analyses using alternative censoring hierarchy, editing DCR and ORR unstratified analyses 
using normal approximation and the z test, and adding Appendix 1.4: Response and 
Evaluation Endpoints.  
As noted in Section 13 in the protocol amendment, the detailed methodology for 
summary and statistical analyses of the data collected in this study are documented in the 
statistical analysis plan (SAP), which is maintained by the sponsor.  There may be 
modifications made to the plans outlined in the protocol but these will not include any 
major modifications of the primary endpoint definition and/or its analysis. Any major 
modifications will be reflected in a protocol amendment. 
2. INTRODUCTION 
2.1. Study Design 
This is a randomized, open-label, multi-center, phase III study of napabucasin plus weekly 
nab-paclitaxel with gemcitabine (Arm 1) vs. weekly nab-paclitaxel with gemcitabine (Arm 
2) for adult patients with metastatic pancreatic ductal adenoacarcinoma (PDAC). 
1132 patients will be randomized in a 1:1 ratio, stratified according to geographical region 
(North America/Western Europe/Australia vs. Japan/Korea vs. Rest of the World), Eastern 
Cooperative Oncology Group (ECOG) performance status (0 vs. 1), and presence of liver 
metastases (yes vs. no).

1If no other standard therapies are available at the time of disease progression, and the 
patient has not experienced any adverse events requiring permanent discontinuation, 
napabucasin may be continued in monotherapy.
2From the time of this amendment, and since the outcome of the interim analysis was 
communicated to investigators, patients may continue protocol therapy if it is believed to 
be in their best interest by the investigator and patient, and with the patient’s informed 
consent. Patients will receive napabucasin, nab-paclitaxel and/or gemcitabine at the same 
dose and schedule that they were receiving prior to the amendment. Patients on Arm 1 may 
continue napabucasin with the Sponsor’s approval. Patients on Arm 1 may discontinue 
napabucasin but choose to continue with nab-paclitaxel and gemcitabine.
Until the time of this amendment, the study proceeded in 28-day (4-week) cycles. 
Napabucasin was administered orally, at 240 mg bid (480 mg total daily dose), with doses 
separated by approximately 8-12 hours. Napabucasin administration began 2-5 days prior 
to the first nab-paclitaxel with gemcitabine infusion. Nab-paclitaxel 125 mg/m2
immediately followed by gemcitabine 1000 mg/m2 was administered on Days 1, 8 and 15 
of every 28-day cycle via intravenous infusion. Tumor assessments will be performed 
every 8 weeks after randomization until objective disease progression or treatment 
discontinuation due to toxicity. 
The study was planned for completion on February 28th, 2020.
2.2. Study Objectives

4. HYPOTHESES AND DECISION RULES 
4.1. Statistical Hypotheses 
The null and alternative hypothesis for the primary endpoint (OS) is:
H0: OS in napabucasin + nab-paclitaxel with gemcitabine ≤ OS in nab-paclitaxel 
with gemcitabine
Ha: OS in napabucasin + nab-paclitaxel with gemcitabine > OS in nab-paclitaxel 
with gemcitabine
4.2. Statistical Power and Sample Size Calculation 
The primary study endpoint of the study is OS in the general study population. 
The study is designed to have a power of 90% and a one-sided alpha of 2.5% to detect a 
20% reduction in the continuous risk of death (HR 0.80, which corresponds to an increase 
of median survival from 8.5 to 10.63 months) in the Intent to Treat (ITT) general study 
population. It is estimated that 864 events will be required to detect a 20% reduction in the 
risk of death which would be observed by randomizing 1132 patients over 24 months with 
patient follow up for an additional 12 months, for total study duration of 36 months. It is 
anticipated that up to 5% dropout rate will occur. When the required number of events for 
the primary endpoint has been reached, all randomized patients still alive will continue 
study follow up through to their deaths.
5. INTERIM ANALYSES, FINAL ANALYSIS, AND UNBLINDING  
5.1. INTERIM ANALYSES AND FINAL ANALYSIS 
Prior to this amendment, there was one interim analysis after 50% of the required number 
of events (432 events) had been observed.
The interim analysis was for futility only, with the futility boundary set at HR ≥ 1. Safety 
data and primary efficacy analysis based on approximately 432 events were presented to the 
DSMB on June 24th, 2019. The DSMB reviewed the results on July 1st, 2019. Based on the 
recommendation of the DSMB, the Sponsor informed investigators on July 2nd, 2019 that 
the study would be discontinued due to futility. For patients enrolled to Arm 1, the Sponsor 
advised that patients stop treatment with napabucasin but given that no safety concerns were 
identified by the DSMB, in cases in which a patient appears to be deriving benefit from 
napabucasin in the opinion of the investigator and approved by the Sponsor and with the 
patient’s informed consent, continuation of protocol therapy was permitted. Patients 
enrolled to Arm 2 were given the option to continue receiving standard of care therapy 
within the study. 
Patients continued to receive protocol therapy until a discontinuation criterion was met or 
until February 28th, 2020, whichever occurred first. 


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 16
As the Interim Analysis data concluded the study, the IA report will be included as an 
appendix to the CSR. The final analysis including data after July 2nd, 2019 will be 
exploratory in nature. This is due to a potentially imbalanced dropout rate of the two 
treatment arms as the study was deemed futile. Therefore, caution is necessary when 
interpreting the results.
At study completion, analysis will be conducted for primary endpoint of OS as outlined 
in Section 3. Additionally, all secondary and exploratory analyses will be performed as 
outlined. 
5.2. UNBLINDING AND DATA SAFETY AND MONITORING COMMITTEE 
Although this is an open-label study, a blinding plan will be implemented to minimize the 
risks of potential Sponsor bias for decision making at the interim analyses and the final 
analysis. 
Specifically, there will be an unblinded reporting team to report complete interim analysis 
results and regular safety updates to an independent Data Safety and Monitoring Board 
(DSMB). DSMB will review the IA results and make recommendations to the Sponsor 
based on the decision rules described in Section 5.1. DSMB will also review safety data 
regularly during conduct of the study. The role and responsibilities of the DSMB will be 
detailed in a separate Charter.
Aggregated data by treatment will not be reviewed or analyzed by the study team until the 
final database release or early termination of the study. SDPO will restrict access to the 
database to only selected team members (or their designees) who have a need to review 
individual unblinded patient information on an ongoing basis for safety and 
pharmacovigilance monitoring.
Adequate procedures will also be implemented so that team members (or their designees) 
who have unblinded information for patients in the study do not disclose and disseminate 
any unblinded information or unblinded data to any blinded personnel until after the official 
database release. The roles and responsibilities of the blinded and unblinded staff will be 
detailed in a separate plan.
6. ANALYSIS SETS 
6.1. Intent-to-Treat Analysis Set 
The Intent-to-Treat (ITT) population is defined as all patients who are randomized.  
Patients will be analyzed according to the treatment arm they were randomized to, 
regardless of any potential errors in dosing.  The ITT population will be  used for primary 
and secondary efficacy endpoint analyses. 
6.2. Safety Analysis Set 
The safety analysis set is defined as all patients who receive at least 1 dose of any study 
drug. Patients will be analyzed according to the treatment they actually received. That is, 
those patients who are randomized to the active arm but receive the regimen in the control 


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 17
arm will be included in the control arm; those patients who are randomized to the control 
arm but receive the regimen in the active arm will be included in the active arm for safety 
analyses.
Safety analysis set will be used for all safety related analyses including treatment emergent 
adverse events (TEAEs), concomitant medication, laboratory tests, and vital signs.
6.3. Response Analysis Set (RAS) 
Response analysis set (RAS) is defined as all ITT patients with measurable disease per 
RECIST 1.1 at randomization.  RAS will be used for the primary analysis of response data 
(ORR and DCR). Response data may also be summarized in the ITT population. 
6.4. PK Analysis Set 
The PK analysis set will include all patients who received at least one dose of study drug 
(napabucasin) and have at least one quantifiable concentration.
6.5. Treatment Misallocations  
If a patient was: 
x
Randomized but not treated, then they will be excluded from analyses of safety and
PK as they have not received at least one dose of study medication. These patients 
will be included in ITT analyses, however.
x
Treated but not randomized, then they will be excluded from the efficacy analyses 
since randomized treatment is missing, but will be reported under the treatment they 
actually received for all safety and PK analyses.
x
Randomized but took incorrect treatment, then they will be reported in the ITT 
analysis under the treatment they were randomized to, and under the treatment they 
actually received for the PK and all safety analyses. 
7. DATA HANDLING 
7.1. Methods for Handling Missing Dates 
All analyses and descriptive summaries will be based on the observed data. Except for the 
data otherwise specified in the language below, missing data will not be imputed or “carried 
forward”. For the patient data listings, no imputation of incomplete dates will be applied. 
The listings will present the incomplete dates without any change.
Missing or Partial Death Dates
x
If the entire date is missing, the death date will be imputed as the day after the date 
last known alive.


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 18
x
If the day or both day and month is missing, the death date will be imputed to the 
maximum of the full (non-imputed) day after the date last known alive and the 
following: 
o
If day is missing, day will be 1st of the month
o
If both day and month are missing, death month and day will be January 1st.
Date of Last Dose of All Study Drugs
No imputation will be done for first dose date.  Date of last dose of study drug, if unknown 
or partially unknown, will be imputed as follows:
x
If the last date of study drug is completely missing and the End of Treatment (EOT) 
eCRF page has not been completed and no death date has been entered, the patient 
should be considered ongoing and the cutoff date for the analysis should be used as 
the last dosing date.  
x
If the last date of study drug is completely or partially missing and there is EITHER 
a completed EOT eCRF page OR a death date available (within the data cutoff 
date), then impute this date as the last dose date:
= 31DECYYYY, if only Year is available and Year < Year of min (EOT date, death 
date) 
= Last day of the month, if both Year and Month are available and Year = Year of 
min (EOT date, death date) and Month < Month of min (EOT date, death date)
= min (EOT date, death date), for all other cases.
x
If patients were never dosed, the date of last dose will be marked as Not Applicable 
and there will be a date of discontinuation on the EOT eCRF page and/or a death 
date on the Death eCRF
Missing Dates in Adverse Events/Concomitant Therapies/Medications
Dates missing the day or both the day and month of the year will adhere to the following 
conventions:
x
The missing day of onset of an AE or start date of a therapy will be set to:
-
the day of the first study treatment, if the onset yyyy-mm is the same as yyyy-
mm of the first study treatment
-
otherwise, the first day of the month that the event occurred
x
The missing day of resolution of an AE or end date of a therapy will be set to:
-
the last day of the month of the occurrence. If the subject died in the same month, 
then set the imputed date as the death date
x
If the onset date of an AE or start date of a therapy is missing both the day and 
month, the onset date will be set to:


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 19
-
the date of the first treatment, if the onset year is the same as the year of the first 
study treatment
-
otherwise, January 1 of the year of onset
x
If the resolution date of an AE or end date of a therapy is missing both the day and 
month, the date will be set to:
-
December 31 of the year of occurrence. If the subject died in the same year, 
then set the imputed date as the death date
x
If date is completely missing, then no imputation will be done and the event will be 
considered as treatment emergent (for AEs) or concomitant (for medications) unless 
the end date rules out the possibility.
Missing Dates in Prior Therapies
Dates missing the day or both the day and month of the year will adhere to the following 
conventions:
x
The missing day of start or end date of prior therapy will be set to:
-
the 15th of the month or date of informed consent, whichever is earlier
x
If the start or end date of a prior therapy is missing both the day and month, the date 
will be set to: 
-
July 1 of the year or date of informed consent, whichever is earlier
x
If date is completely missing, then no imputation will be done 
Missing Efficacy Endpoints
For primary and secondary efficacy analyses no values will be imputed for missing data. 
For time to event endpoints, non-event observations will be censored. For ORR/DCR, 
patients with no post-baseline tumor evaluations or missing baseline tumor evaluation 
will be counted as non-responders.  
Missing Age
Age will be computed from birth date to the date of Informed Consent, as (Date of 
Informed Consent – Date of Birth +1)/365.25 rounded down to the nearest integer. 
x
If birth date is missing day, day will be set to the 15th to minimize bias
x
If missing both month and day, birth date will be set to July 1 of the birth year
Missing QoL Data
Missing items in a scale in EORTC QLQ-30 will be handled by the following methods:  
Values will be imputed for missing items by “assuming that the missing items have 


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 20
values equal to the average of those items which are present” for any scale in which at 
least half the items are completed.  A scale in which less than half of the items are 
completed will be treated as missing. No imputation will be conducted at a specific visit 
if data is completely missing.
7.2. Definition of Baseline Values 
x
Efficacy: The last non-missing measurement on or prior to the date of 
randomization will serve as the baseline measurement, so long as this assessment 
was taken within 28 days of randomization. Any imaging assessments performed 
outside the time window will be considered protocol deviations and will be 
evaluated on a case by case basis.
x
Safety: The last non-missing assessment prior to the date of the first study drug 
administration (either napabucasin or nab-paclitaxel or gemcitabine, whichever was 
administered first) will be used as the baseline assessment. In the case this value is 
missing, the last non-missing assessment prior to or on the randomization date will 
be used as baseline assessment.
x
Other baseline characteristics: The last non-missing measurement on or prior to the
date of randomization will serve as the baseline measurement. In the event such a 
value is missing, the last non-missing assessment completed prior to the date of the 
first dose of study drug administration (either napabucasin or nab-paclitaxel or 
gemcitabine, whichever was administered first) will be used as the baseline 
assessment.
7.3. Study Day 
Study day for safety analysis is calculated as:
x
Assessment date – first dose date + 1; if the assessment was performed on or after 
the first dose date.
x
Assessment date – first dose date; if the assessment was performed prior to the 
first dose date.
Study day for efficacy analysis is calculated as:
x
Assessment date – randomization date + 1; if the assessment was performed on or 
after the randomization date.
x
Assessment date – randomization date; if the assessment was performed prior to 
the randomization date.
7.4. Visit Windows 
All data will be categorized based on the scheduled visit at which it was collected.  These 
visit designators are predefined values that appear as part of the visit tab in the eCRF.

Page 21
7.5. Dropouts  
Time to event parameters will be censored if patients drop out (withdraw from consent or 
lost to follow-up) before documentation of the events (progressive disease / death).  Rules 
for censoring for PFS are detailed in Appendix 1.2 Censoring for Time to Event Data.
7.6. Pharmacokinetics 
The handling of BLQ values for nonlinear mixed-effects modeling (AKA: Population-PK, 
or Pop-PK) will be described in a separate analysis plan.  For the purpose of data tabulation, 
summary statistics, and by-time point graphics, BLQ values will be treated as zero.  
8. STATISTICAL METHODOLOGY AND STATISTICAL ANALYSES 
8.1. Statistical Methods 
Whilst every effort has been made to pre-specify all analyses in this statistical analysis 
plan, if any additional exploratory analyses are found to be necessary, the analyses and the 
reasons for them will be detailed in the clinical study report (CSR).
Analysis for Time to Event Data 
Time-to-event curves between the two treatment groups will be compared with a one-sided 
stratified log-rank test at significance level of 0.025 (one-sided) adjusting for the 
stratification variables at randomization. Stratified and unstratified Cox proportional 
hazards model will be used to estimate the hazard ratio as well as 2-sided 95% confidence 
intervals (CI), and may be used to explore the potential influences of the baseline factors 
(eg, age, gender and ethnic origin, etc) on the time-to-event data. The time-to-event data 
will also be summarized using the Kaplan-Meier method and displayed graphically when 
appropriate (2). Median event times and 2-sided 95% CIs for each time-to-event endpoint 
will be provided. The 6 month, 1 year, and 18 month survival probability will be estimated 
using the Kaplan-Meier method and a 2-sided 95% CI will be calculated using the normal 
approximation to the log transformed cumulative hazard rate.
Analysis for Binary Data 
Descriptive statistics (frequency and percentage) for binary endpoints will be presented 
by treatment group. CMH test will be used for comparison of the two treatment groups, 
adjusting for the randomization stratification variables. Two-sided Z test will be used for 
comparison of the two treatment groups without stratification. In addition, the treatment 
difference and 95% CI based on the Miettinen and Nurminen method (5) adjusting for 
the stratification factors will be displayed. For unstratified analyses, the treatment 
difference and 95% CI will be based on the normal approximation method, and may be 
used to explore the potential influences of the baseline factors on the binary endpoints.

Analysis for Continuous Data 
Descriptive statistics, such as the mean, standard deviation, median, minimum, and 
maximum values, will be provided for continuous endpoints. Linear or non-linear models 
may be employed to analyze the continuous data. 
Analysis for Quality of Life Data 
Summary statistics for Quality of Life will be provided by treatment for Functional, 
Symptom and Global health status raw scores as well as for linearly converted scores on 
the scale of 0-100. The mean EORTC QLQ-C30 QoL changes scores from baseline at 
time 2 (~8 weeks post randomization) and time 4 (~16 weeks post randomization) for 
the physical function and global health status/qualify of life subscale scores will also be 
presented. Wilcoxon tests will be used to compare the difference at each of these two 
time points between the two treatment arms for each of these two subscales. In addition, a 
chi-square test will be used to compare the distribution of patients who have improved, 
are stable, or have worsened from baseline between the two arms. A Fisher’s exact test 
will be used to compare between the two arms the proportion of patients with 
deterioration in physical function and global QoL at time 2 and time 4. 
8.2. Statistical Analyses  
Standard Analysis
Study Conduct and Patient Disposition
Patient disposition includes the number and percentage of patients for the following 
categories:  patients in each of the study populations, patients discontinued from the 
treatment, primary reason to discontinue from the treatment, patients discontinued from the 
study, and primary reason to discontinue from the study.  All percentages will be based on 
the number of patients in the ITT population. 
Demographic and Baseline Characteristics
Baseline characteristics such as demographics, baseline disease characteristics, prior 
therapies, and ECOG performance score will be tabulated and listed. 
Prior and Concomitant Medications
Prior and concomitant medications will be coded to ATC (Anatomical Therapeutic 
Chemical) classification and Drug Class using WHO Drug Dictionary (WHO-DD) March 
2016, and will be listed.
Medications that start and stop prior to the date of first treatment administration will be 
classified as ‘prior’ medications. If a medication starts on or after the date of first treatment 
administration up to the last dose date of study medication (inclusive), then the medication 
will be classified as ‘concomitant’.

Summaries of prior and concomitant medications will be provided by level 3 ATC 
classification and preferred term using frequencies and percentages for the ITT population. 
A separate concomitant medications table using preferred base and level 4 ATC 
classification will also be provided using frequencies and percentages for the safety 
analysis set. 
Prior Treatment 
Prior treatment will be summarized by overall and listed for each patient in the ITT 
population.
Prior cancer surgery will be coded by System Organ Class (SOC) and Preferred Term (PT) 
using the Medical Dictionary for Regulatory Activities (MedDRA® v.19.0) and 
summarized by MedDRA PT within MedDRA SOC.  The number and percentage of 
patients in each type of prior cancer surgery will also be reported by overall.
The total dose of prior cancer radiotherapy will be summarized. The number and 
percentage of patients with radiation to different anatomical locations will be reported, 
along with indication. 
Prior cancer therapies will be summarized by the number of unique agents per patients, the 
number and percentage of patients reporting each agent, time from start of first anticancer 
therapy to first dose date of napabucasin, and time from end of last anticancer therapy to 
first dose date of napabucasin. Prior cancer therapies will be coded to Agent Received using 
WHO Drug Dictionary (WHO-DD) March 2016. 
Concomitant Palliative and Supportive Care Therapies
Concomitant palliative and supportive care therapies will be summarized by overall and 
listed for each patient in the ITT population.
Concomitant palliative and supportive care therapies will be coded using WHO Drug 
Dictionary (WHO-DD) March 2016. 
New Anti-cancer Treatment
New anti-cancer therapy will be derived from Post protocol cancer therapy.
New anti-cancer therapy will be summarized by type of therapy and median time to post 
protocol systemic therapy from randomization. Median time will be calculated using the 
Kaplan Meier Method and CIs estimated using the Brookmeyer Crowley method. 
Patients who have not received a new anti-cancer therapy at the time of interim or final 
analysis will be censored at the date of data cutoff.
Medical History
Medical history will extracted from both medical history and AE CRFs.
Adverse Events listed on the AE CRF, with the “Is this an ongoing medical history 
condition present at date of informed consent?” marked as “Yes” will be considered

medical history, as these events were ongoing at the time of informed consent and prior to 
randomization.
Medical history will be coded by SOC and PT using MedDRA v19.0.  Medical history will 
be summarized by SOC and PT using the number and percentage of patients for the ITT 
population. 
Dose Changes
The details of napabucasin dose change are outlined below. 
x
Dose Held Due to Non-AE - 2 or more consecutive doses held (AM-PM or PM-AM) 
due to patient forgot, patient decision or other reason.
x
Dose Held Due to AE - 2 or more consecutive doses held (AM-PM or PM-AM) due 
to adverse event.
o
Restarted at the same dose - Restarted at a dose the same as the previous non-
zero dose at the time of dose held.
o
Restarted as reduced dose (dose-decrease) - Restarted at a dose decreased 
from the previous non-zero dose at the time of dose held.

Dose increase to partial dose following reduction - An increase to 
<240 mg for 2 or more consecutive doses (AM-PM or PM-AM) 
following restart at reduced dose.

Dose increase to full dose following reduction - An increase to 240 mg 
for 2 or more consecutive doses (AM-PM or PM-AM) following 
restart at reduced dose.
x
Permanently Discontinued Due to AE.
Extent of Exposure Exposure may be summarized (per run-in and/or first 28 days and/or 
overall) as dose received (cumulative dose or actual dose intensity) or as dose received 
relative to intended dose (relative dose intensity [RDI]).  
The information that will be summarized depends on how the study drug is dosed (e.g., 
infusion cyclical, oral daily, oral cyclical).  
In what follows, “time unit” can be e.g., weeks or days.
Treatment duration in days
For napabucasin:
x
Overall intended treatment duration = earliest date of {latest date of {start date of 
last cycle +27 days, last dose date of Napabucasin}, death date, end of study date} 
– earliest date of {first dose date of Napabucasin and/or nab-paclitaxel and/or 
gemcitabine}+1.
x
Run-in treatment duration = actual number of days in run-in period.


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 25
x
First 28 days intended treatment duration = earliest date of {start date of 1st cycle 
+ 27 days, death date, end of study date} – start date of 1st cycle +1.
For backbone treatment:
x
Overall intended treatment duration = (earliest date of {latest date of {start date of 
last cycle +27 days, last dose date of Napabucasin}, death date, end of study date} 
– earliest date of {first dose date of nab-paclitaxel or gemcitabine (whichever 
backbone duration you are calculating)} +1)/ 7.
x
First 28 days intended treatment duration = (earliest date of {start date of 1st cycle 
+ 27 days, start date of nab-paclitaxel or gemcitabine (whichever backbone 
duration you are calculating) within Day 28 ±3 window -1 } – start date of 1st 
cycle +1)/ 7.
Note that the actual end of treatment date in this analysis is not the collected end of 
treatment date in the eCRFs, as the actual end of treatment date in this analysis is being 
derived and may be different from what was recorded by sites. 
Cumulative dose in a period or overall is the sum of the actual doses received in a period 
or overall, respectively.  
Actual Dose Intensity [DI]
x
Overall actual DI = overall accumulative dose in mg or mg/m2 / overall intended 
treatment duration in days or weeks.
x
Run-in actual DI = actual total dose in mg in run-in / actual treatment duration in 
days in run-in.
x
First 28 days actual DI = actual total dose in mg or mg/m2 in first 28 days / 
intended treatment duration in days or weeks in first 28 days. 
Relative Dose Intensity (RDI): The basic intent is to evaluate dose per time unit factoring 
in dose reductions, interruptions, or delays.  
x
Relative dose intensity (RDI) by period and overall
o
Intended DI (dose unit/time unit) = [intended cumulative dose per period] / 
[intended number of time units in a period]  
o
Overall RDI (%) = 100 ×  [overall actual DI] / [intended DI] 
Note:
x
The intended dose level is fixed at the start of treatment rather than the start of a 
cycle

o
One exception is for all backbone therapies. All backbone therapies 
incorporate BSA to calculate each dose. Therefore, the BSA to be used for 
calculating each dose of the backbone therapies will be using the Mosteller 
method (see below) based on the last available weight and height prior to 
each infusion. 
o
BSA [m2] = ((Height [cm] × Weight [kg])/3600) × 0.5
o
Calculated doses will be rounded to the nearest integer
o
Cumulative dose, actual dose intensity and relative dose intensity will 
remain missing if they cannot be derived due to missing BSA. Height from 
the most recent earlier visit can be used if height is missing.
x
The intended cumulative dose of a combination drug per cycle is constant for all 
cycles
o
One exception is for all backbone therapies after the updated BSA or weight 
calculation prior to each infusion. The updated dose level based on 
changing BSA or weight should be considered when calculating intended 
cumulative dose of these drugs per cycle
x
The intended cumulative dose of napabucasin per period is calculated by (intended 
dose level per day) x (intended period duration in days)
x
Dose unit of napabucasin is mg, dose unit of a combination drug is mg/m2
Treatment compliance
Napabucasin compliance overall
Overall: Treatment compliance (%) for napabucasin =
(Cumulative actual total dose /total planned or intended dose) x 100
Daily treatment compliance will be reported for each patient for the following dose-levels 
and intervals:
x
The % of days the patient received a total dose of at least 480 mg napabucasin out 
of actual treatment duration in days.   
x
The % of days the patient received a non-zero dose of napabucasin out of actual 
treatment duration in days.
Daily treatment compliance will be grouped according to the following categories: < 
60%,t 60% - < 80%, t 80% - < 90%, t 90%, and will be summarized for the treatment 
group of napabucasin plus Nab-Paclitaxel + Gemcitabine IV.
Combination drugs compliance overall
Overall: Treatment compliance (%) for combination drugs =
(Number of treatments administered /number of treatments that should have been 
administered) x 100

Analysis for Primary Endpoint 
8.2.2.1. Overall Survival 
Overall Survival in the general study population, the primary endpoint of this study, is 
defined as the time from randomization to death from any cause. Patients who are alive at 
the time of interim or final analysis or who have dropped out will be censored at their last 
date known to be alive on or before the date of data cutoff. Patients will be analyzed in the 
arm to which they are randomized regardless of the treatment they received (intent-to-treat 
analysis). OS in months is calculated as (date of death/Last known to be alive date – date 
of randomization + 1)/30.4375.
The survival experience of patients in both treatment groups will be summarized by the 
Kaplan-Meier method and compared primarily by a stratified log-rank test adjusting for 
stratification variables at randomization, including geographical region (North 
America/Western Europe/Australia vs. Japan/Korea vs. Rest of the World), ECOG 
performance status (ECOG 0 versus ECOG 1), and presence of liver metastases (yes versus
no). The hazards ratio and 95% CI will be obtained using the Stratified Cox PH Model. If 
any randomized stratification factor proves to have an inadequate sample size, it will be 
dropped from the primary analysis or pooling will be applied. Details will be determined 
in a blinded fashion prior to database lock. The survival probability at 6 months, 1 year, 
and 18 months will be summarized using the Kaplan-Meier method. 
Sensitivity analysis using Cox proportional hazards model based on actual stratified factors 
will be performed. An unstratified, 1-sided log-rank test will also be performed for 
sensitivity using an unstratified Cox PH model to obtain HR and the 95% CI. A multi-
variate Cox PH model stratified by the stratification factors and including other baseline 
factors (as described in the subgroup analyses below) will also be conducted. Additional 
analyses for each stratification level will be performed using the Kaplan-Meier method for 
each treatment for each stratification level. A stratified, 2-sided log-rank test will be
performed along with a stratified Cox PH model to obtain HR and 95% CI. Additional 
analyses may be conducted using the unstratified Cox proportional model incorporating 
each baseline factor if deemed adequate and necessary.  
Subgroup analysis and the corresponding forest plot will be conducted by the stratification 
factors at baseline as mentioned above as well as the following factors: 
x
Primary tumor location (head versus body/tail of pancreas)
x
Level of CA19-9 (normal versus >ULN and <59 x ULN versus >59 x ULN)
x
Age (< 65 versus > 65)
x
Sex (male versus female)
x
Number of metastatic sites at baseline (1 versus > 2)
x
Race (white, black, Asian, other)
x
Smoking (Yes versus No)
x
Prior adjuvant chemotherapy (Yes versus No)

Analyses for Secondary Endpoints 
8.2.3.1. Key Secondary Efficacy Endpoints Analysis 
The following key secondary outcomes will be also be assessed.  
PFS in the General Study Population
PFS in the general study population is defined as the time from randomization to the first 
objective documentation of disease progression or death due to any cause. If a patient has 
not progressed or died at the time of interim or final analysis (up to the date of data cutoff), 
PFS will be censored on the date of the last tumor assessment (up to the date of data cutoff). 
PFS in months is calculated as (First event date/Censored Date – date of randomization + 
1)/30.4375.
The difference in PFS between treatment arms will be analyzed using the log rank test 
stratified by stratification factors.  The 1-sided p value from the stratified log-rank test 
will be reported along with the median event time (and other quartiles) and corresponding 
2-sided 95% CI for each treatment arm.  Estimates of the PFS curves obtained from the 
Kaplan-Meier method will be presented along with a graphical presentation of PFS 
curves.  The Cox PH model stratified for randomized stratification factors will be fitted 
and the estimated hazard ratio and 2-sided 95% CI will be provided. 
Additional analyses may be conducted using the unstratified Cox proportional model 
incorporating each baseline factor if deemed adequate and necessary.  
DCR in the General Study Population
DCR is defined as the proportion of patients with a documented complete response, partial 
response, and stable disease (CR + PR + SD) based on RECIST 1.1. The primary estimate 
of DCR will be based on the Response Analysis Set (RAS).
DCR will be summarized for each treatment arm along with the corresponding exact 2-
sided 95% CI using the Clopper Pearson method.  Differences of DCR between the two 
arms will be compared using a 1-sided Cochran-Mantel-Haenszel test stratified for 
stratification factors. The treatment difference of DCR and its 95% CI based on the 
Miettinen and Nurminen (M&N) method adjusting for stratification factors will be provided 
along with the DCR and 95% CI for each stratification factor level for each treatment 
arm.  


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 29
Additional analyses may be conducted using the unstratified one-sided Z test 
incorporating each baseline factor to compare the differences of DCR between the two 
arms. The treatment difference of DCR and its 95% CI may also be obtained using the 
normal approximation method.
ORR in the General Study Population
ORR is defined as the proportion of patients with a documented complete response and 
partial response (CR + PR) based on RECIST 1.1. The primary estimate for ORR will be 
based on the RAS.
ORR will be analyzed similarly as DCR. 
8.2.3.2. Other Secondary Endpoint Analysis 
QoL Analysis
The QoL of patients will be assessed using EORTC QLQ-30. The EORTC QLQ-30 is a 
self-administered cancer specific questionnaire with multi-dimensional scales. It consists 
of both multi-item scales and single item measures, including five functional domains, a 
global quality of life domain, three symptom domains, and six single items. Scoring of the 
EORTC QLQ-30 data will be completed following the procedures recommended by the 
EORTC Study Group on Quality of Life. For each domain or single item measure a linear 
transformation will be applied to standardize the raw score to range between 0 and 100. 
Questionnaire compliance rates will be ascertained for each group at each measurement 
time point. Mean baseline scores for each subscale and summary scores will be calculated.
Compliance at an assessment time point is defined as the number of patients who were 
assessed divided by the expected number of patients at that time point. The expected 
number of patients:
x
at baseline is equal to the number of patients randomized 
x
at any post-baseline visit is equal to the number of patients who are alive and have 
not progressed 
A subject who answers at least one item at a time point is considered to have been assessed. 
The endpoints in QoL analysis are the mean EORTC QLQ-C30 QoL change scores from 
baseline at time 2 and time 4 for the physical function and global health status/quality of 
life subscale scores. Wilcoxon tests may be used to compare the difference at each of these 
two time points between two treatment arms for each of these two subscales. 
Summary statistics will be provided by treatment for Functional, Symptom and Global 
health status raw scores for QoL-C30 as well as for linearly converted scores on the scale 
of 0-100. 
Note the raw score is: RawScore=RS=(I1+I2+…+In)/n, where I1, I2,…and In are the nth 
component in the categories of functional, symptom or global health status scales. 


Protocol CanStem111P
Statistical Analysis Plan
SDPO CONFIDENTIAL
Page 30
The linearly converted score (LCS) for Functional scales is defined as:
Linearly Converted Score =LCS = (1- (RS-1)/Range)) ×100 
For Symptom scales or Global health status: 
Linearly Converted Score =LCS = (RS-1)/Range ×100
The following gives the LCS for all the scales: 
Functional scale’s scores:
o
Physical functioning:
(1 - ((Q1+Q2+Q3+Q4+Q5)/5 -1)/3) * 100
o
Role functioning:
(1 - ((Q6+Q7)/2-1)/3) * 100
o
Emotional functioning:
(1 - ((Q21+Q22+Q23+Q24)/4-1)/3) * 100
o
Cognitive functioning:
(1 - ((Q20+Q25)/2-1)/3) * 100
o
Social functioning:
(1 - ((Q26+Q27)/2-1)/3) * 100
Global health status score:
o
Global QOL: ((Q29+Q30)/2-1)/6 * 100
Symptom scale’s scores:
o
Fatigue:
((Q10+Q12+Q18)/3-1)/3 * 100
o
Nausea and vomiting:
((Q14+Q15)/2-1)/3 * 100
o
Pain:
(Q9+Q19)/2-1)/3 * 100
o
Dyspnea:
((Q8-1)/3 * 100
o
Insomnia:
(Q11-1)/3 * 100
o
Appetite loss:
(Q13-1)/3 * 100
o
Constipation:
(Q16-1)/3 * 100
o
Diarrhea:
(Q17-1)/3 * 100
o
Financial difficulties:
(Q28-1)/3 * 100
Missing  data handling for missing items in a scale are specified in Section 7.1.  
The QoL assessment is performed prior to randomization and during protocol treatment 
after randomization. Since exact time of assessment may vary from patient to patient, it is 
necessary to provide a window for each QoL time point.  What follows is a description of
how to assign a questionnaire to a discrete time point:
Relative Days (REL_Day) from Randomization = 
x
Assessment date – randomization date+1; if the assessment was performed on or 
after the randomization date.
x
Assessment date – randomization date; if the assessment was performed prior to 
the randomization date.

Note that if more than 1 questionnaire is available for the baseline window, then the latest 
non-missing measurement, per question, will be considered as the baseline. If more than 
1 questionnaire is available at a time point other than baseline, then the average (per 
question) of the non-missing measurements will be used. 
If there are multiple records in the same day to 1 item, the more severe answered will be 
counted. 
QOL Response Analysis for EORTC QLQ-C30
For EORTC-QLQ-C30, QoL response for functional scales and global health status is 
calculated as follows: A change score of 10 points from baseline is defined as clinically 
relevant.  Patients are considered to have clinical improvement if reporting a score 10-
points or better than baseline at any time of QoL assessment.  Conversely, patients are 
considered worsened if reporting a score minus 10-points or worse than baseline at any 
time of QoL assessment without any clinical improvement.  Patients whose scores are 
between 10-point changes from baseline at every QoL assessment will be considered as 
stable.  In contrast to functional scales, for the determination of patient’s QoL response, 
classification of patients into improved and worsened categories is reversed for symptom 
scales.  A Chi-square test may then be performed to compare the distributions of these 
three categories between the two arms.
The proportion of patients in either arm with at least a minimum of 10 unit(s) 
deterioration in change scores at both 8 and 16 weeks will be compared by means of
Fisher’s exact test.
8.2.3.3. PK Analysis 
Plasma napabucasin concentrations will be tabulated by Day within Cycle, nominal time 
and dose in the case of dose reduction if appropriate.  The listing will include actual 
sampling time relative to the napabucasin dose administered on the day of the PK sample 
collection.  Summary statistics by Day within Cycle, and irrespective of Day and Cycle, 
will be presented including arithmetic mean, arithmetic standard deviation, arithmetic-
based percent coefficient of variation, geometric mean, geometric standard deviation, 
maximum, median, minimum, and sample size.
Exploratory analyses may be performed by  Pop-PK analysis of napabucasin, possibly in 
conjunction with data from other napabucasin studies. The exposure-response relationship 
between clinical and safety endpoints and napabucasin/nab-paclitaxel with gemcitabine 
exposure may also be examined.

Page 32
The procedures for the population PK modeling, including model evaluation, will be 
described in a seperate Pop-PK analysis plan.  The corresponding results will be reported 
in a separate document, not in the clinical study report (CSR).  
8.2.3.4. Biomarker Analysis - Correlative Studies 
Pre-clinical and clinical studies conducted by SDPO have identified several biomarkers in 
tumor tissues whose levels either increase or decrease upon exposure to napabucasin.  
Tumor archival tissue and biopsies will be collected as described in Protocol (1) Section 
12.3. The correlations between the biomarker results, and pharmacokinetic parameters and 
measures of anti-tumor/anti-cancer efficacy signals will be explored if data allow and it is 
deemed appropriate.   
Specifically, the relationship between phospho-STAT3 (pSTAT3) and the clinical 
outcomes with napabucasin therapy may be explored. The following efficacy endpoints 
may be analyzed by pSTAT3 status (positive and negative and unknown):
x
Primary Endpoint: Overall Survival (OS),
x
Secondary Endpoint: Progression Free Survival (PFS), and
x
Objective Response Rate (ORR) and Disease Control Rate (DCR)
Safety, demographics, baseline disease characteristics, and prior therapy may be 
summarized by treatment by pSTAT3 status (positive or negative or unknown) in all the 
patients with biomarker data.  
Analyses for Other Safety Endpoints 
All treatment emergent adverse events, lab abnormalities, vital signs, ECOG, physical 
exam, and ECG data analyses will be summarized based on the safety analysis set. 
8.2.4.1. Adverse Events 
Overall Summary of AEs 
An AE will be regarded as treatment-emergent, if
x
it occurs for the first time on or after the first dose date of either napabucasin or 
nab-Paclitaxel or gemcitabine up to 30 days after the last dose of study treatment 
(or up to any time if serious and considered related to study treatment); or
x
it occurs prior to first dose date of either napabucasin or nab-Paclitaxel or 
gemcitabine and worsens in severity on therapy or up to 30 days after the last dose 
of study treatment  (or up to any time if serious and considered related to study 
treatment)

Summary of TEAEs by System Organ Class and Preferred Term 
The number and percentage of patients who experience any TEAE and TEAEs of grade 3 
or higher (Grade 3, 4, 5) will be summarized by SOC and PT. A summary of TEAEs by 
PT will be presented in the descending order of frequency counts for all grades and grade 
3 or higher. A summary of AEs by PT and maximum CTCAE grade will be presented.The

Page 34
most commonly reported AEs using different cutoffs (e.g., 2%, 5% or 10% or more of 
patients in either arm) may also be summarized by PT as needed for various reporting 
purposes. Adverse events associated with permanent discontinuation/dose reduction/dose 
interruption of either napabucasin and/or nab-paclitaxel and/or gemcitabine will also be 
summarized by SOC and PT and maximum CTCAE grade.
Treatment Related TEAE
AEs reported with a relationship to a treatment considered by the investigator to be 
‘possible’, ‘probable’ or ‘definite’ will be considered “Related” to study treatment or
paclitaxel or gemcitabine, respectively. AEs reported with a relationship to a treatment 
considered by the investigator to be “unlikely” or “unrelated” will be considered as “Not 
Related” to study treatment or nab-paclitaxel or gemcitabine, respectively. Missing 
relationship will be considered as “Related”.  Similar summaries of all causality AEs will 
be provided. TEAEs related to study drug, leading to dose modification, dose reduction, 
and dose discontinuation will be summarized by SOC and PT.
Serious TEAE and Death
Treatment emergent SAEs and treatment related TESAEs will be summarized by MedDRA 
SOC and PT and Maximum CTCAE grade. 
Patients who experienced a TESAE during AE reporting period will be listed for all safety 
patients.  The number and percentage of patients who experience any treatment emergent 
SAE will be summarized by SOC, PT and maximum CTCAE grade. Similar summary for 
treatment related TESAEs will be provided as well. 
Deaths that occur on or after the first dose of study treatment and within 30 days of last 
dose of any study treatment will be summarized. The number and percentage of patients
who died during the study treatment and within 30 days after the last dose will be presented.
TEAEs leading to death will be summarized by MedDRA SOC and PT. 
A listing of death data will also be provided and it will include all deaths that occurred 
during the reporting period for deaths which starts from the signing of informed consent to 
the end of the follow up period.  The listing will include date of death, and the number of 
days relative to the administration of first and last dose. 
Clustered Treatment Emergent Adverse Events
Selected treatment emergent adverse events were pre-specified for additional focus due to 
the potential clinical significance of the event and/or the potential association with the 
investigational product.  These events include those in the standard MedDRA (narrow or 
broad, as noted) query terms of:  non-infectious diarrhea (narrow SMQ), gastrointestinal 
nonspecific inflammation (narrow SMQ), gastrointestinal haemorrhage (narrow SMQ), 
gastrointestinal perforation (narrow SMQ), gastrointestinal obstruction (narrow SMQ),  
acute renal failure (narrow SMQ), haematopoietic leukopenia (broad SMQ),

hematopoietic erythropenia (broad SMQ), and hematopoietic thrombocytopenia (broad 
SMQ).  Other events include the following sponsor derived terms: Abdominal pain, 
fatigue, hypotension, and torsade de Pointes. Tables listing the incidence, maximum 
severity, relation to study drug, dose modification of study drug, and death due to these 
events in the safety analysis set will be generated.
8.2.4.2. Laboratory Data 
For the purposes of summarization in both the tables and listings, all laboratory values will 
be converted to standardized units.  If a lab value is reported using a non-numeric qualifier 
(eg, less than (<) a certain value, or greater than (>) a certain value), the given numeric 
value will be used in the summary statistics, ignoring the non-numeric qualifier. 
Laboratory test results will be summarized according to the scheduled sample collection 
time point.  Change from baseline will also be presented.  Unscheduled laboratory test 
results will be listed and included in laboratory shift tables.  The parameters to be analyzed 
are as follows:
x
Hematology:  hemoglobin, hematocrit, ANC, neutrophils, lymphocytes, 
monocytes, eosinophils, basophils, platelets, and white blood cell (WBC) count
x
Biochemistry:  blood urea nitrogen, creatinine, total bilirubin, LDH, albumin, 
alkaline phosphatase, AST, ALT, sodium, potassium, magnesium, phosphoros.
Shift tables will be constructed for laboratory parameters to tabulate changes in NCI 
CTCAE for toxicity (version 4.0) from baseline to post baseline worst CTC grade.  
Parameters to be tabulated will include:
x
Hematology: ANC, hemoglobin, platelets, WBC
x
Biochemistry: ALT, AST, alkaline phosphatase, creatinine, total bilirubin, 
magnesium, potassium, sodium, and phosphoros.
Listing will also be presented for urinalysis values.
x
Urinalysis: specific gravity, protein, occult blood, glucose
Maximum change versus baseline figures and E-DISH scatter plots for key lab parameters 
will be produced, including but not limited to liver function tests (ALT, AST, ALP and 
total bilirubin).
A listing of all lab parameters including hematology, biochemistry, urinalysis will be 
provided, including the test result, units, normal range (H and L) and change from baseline, 
and CTCAE grades if grading applies.  Patients who developed toxicities of grade >= 3 
will also be listed.

10. APPENDICES  
10.1. Appendix 1.1 DATA DERIVATION DETAILS 
Table 2 Response Criteria 
Evaluation of target lesions
Complete Response (CR):
Disappearance of all target lesions
Any pathological lymph nodes must have reduction in short axis of 
<10mm
Partial Response (PR):
At least a 30% decrease in the sum of the LD of target lesions, taking 
as reference the baseline sum LD
Progressive Disease (PD):
At least a 20% increase in the sum of the LD of target lesions, taking 
as reference the smallest sum LD recorded since the treatment 
started.  In addition to the increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5mm.   The appearance 
of one or more new lesions is also considered progression
Stable Disease (SD):
Neither sufficient shrinkage to qualify for PR nor sufficient increase 
to qualify for PD, taking as reference the smallest sum LD since the 
treatment started
Evaluation of non-target lesions
Complete Response (CR):
Disappearance of all non-target lesions and normalization of tumor 
marker level.  All lymph nodes must be non-pathological in size 
(<10mm short axis)
Non-CR/Non-PD
Persistence of one or more non-target lesion(s) and/or maintenance 
of tumor marker level above normal limits
Progressive Disease (PD):
Appearance of one or more new lesions and/or unequivocal 
progression of existing non-target lesions
The best overall response (BOR) is the best response recorded from the randomization date 
until disease progression/recurrence or start of new anti-cancer therapy and is determined as 
indicated in Table 3. BOR is derived from the sequence of overall response. Assessment done 
after PD or after “new anti-cancer” treatment but prior to PD will not be considered evaluation 
of best overall response. Tumor assessments will be performed every 8 weeks. BOR derivation
(based on unconfirmed response) is derived from the sequence of overall response determined 
by the following order:
x
CR:  One objective status of CR documented before progression or start of new anti-
cancer therapy. 
x
PR:  One objective status of PR documented before progression or start of new anti-
cancer therapy, but not qualifying as CR.
x
SD:  At least 1 objective status of SD or better documented within at least 1 nominal 
scan interval (8 weeks – 5 days window = 51 days) after start date and before
progression and the start of new anti-cancer therapy, but not qualifying as CR or PR.
x
PD:  Progression documented within 2 nominal scan intervals (or 16 weeks + 5 days 
window = 117) after start date and not qualifying as unconfirmed CR, unconfirmed 
PR, or SD.

NE:  All other cases.  Note that reasons for NE should be summarized and the following 
reasons could be used: 
•
Early death (Note: death prior to 8 weeks after start date)
•
No post-baseline assessments 
•
All post-baseline assessments have overall response NE
•
New anti-cancer therapy started before first post-baseline assessment
•
SD too early (<8 weeks after randomization date)
•
PD too late (>16 weeks after randomization date)
Special and rare cases where BOR is NE due to both early SD and late PD will be classified as 
‘SD too early’.

Disease Control Rate (DCR) is the proportion of patients with a documented CR, PR, or SD 
based on RECIST 1.1 as determined by the investigator assessment collected in the CRFs, 
relative to the RAS.

Objective response rate (ORR) is defined as the proportion of patients with a documented 
complete response (CR) or partial response (PR) based on RECIST 1.1 as determined by the 
investigator assessment collected in the CRFs, relative to the RAS.
The patients will be considered as non-responder until proven otherwise.  Thus, the following 
patients are considered non-responders:
x
Do not have CR or PR while on study; or 
x
Do not have a baseline or post-baseline tumor evaluation; or 
x
Do not have an adequate baseline tumor evaluation; or 
x
Receive anti-tumor treatment other than the study medication prior to reaching a CR or 
PR; or 
x
Die, progress, or drop out for any reason prior to reaching a CR or PR. 
Progression free survival (PFS) is defined as the time from the date of randomization to the 
date of PD, or death due to any cause, whichever comes first. If neither event has been 
observed, then the patient will be considered as censored.  PFS (in months) will be calculated 
as (first event date – date of randomization + 1) / 30.4375.  Sensitivity analyses for PFS may 
be conducted if deemed necessary.
Overall survival (OS) is defined as the time from the date of randomization to the date of death 
from any cause. Patients who are still alive at the time of the final observation, or who have 
become lost to follow-up will be censored at their last date of contact. OS in month is calculated 
as (date of death – date of randomization +1) / 30.4375. Sensitivity analyses for OS may be 
conducted if deemed necessary.
10.2. Appendix 1.2 Censoring for Time to Event Data  
Table 4 summarizes the censoring rules for the PFS primary analysis. Table 5 shows the 
general reasons for PFS censoring for primary analysis and where the primary analysis

Date of Last Contact 
The date of last contact will be derived for patients not known to have died at the analysis data 
cutoff date using the latest complete date (non-imputed) among the following:
x
All patient assessment dates (e.g., blood draws [laboratory, PK], vital signs, 
performance status, ECG, tumor assessments, concomitant radiation, surgery)  
x
Start and end dates of follow-up anti-cancer therapies 
x

alive)
x
Study drug start and end dates
x
Randomization date
x
Date of discontinuation on disposition eCRF pages (do not use if reason for 
discontinuation is lost to follow-up or death).
Note: 
1.
This list is not all inclusive and should be agreed upon by the 
study team according to the data collected in the CRF
2.
Only dates associated with patient visits or actual examinations 
of the patient should be used. Dates associated with a technical 
operation unrelated to patient status (e.g., the date a blood 
sample was processed) should not be used. 
3.
Assessment dates after the cutoff date will not be applied to 
derive the last contact date.

10.4. Appendix 1.4 Response and Evaluation Endpoints 
Response and progression will be evaluated in this study using the revised international 
criteria (1.1) proposed by the RECIST (Response Evaluation Criteria in Solid Tumors) 
committee.
1.1.1
Measurable Disease 
Measurable tumor lesions are defined as those that can be accurately measured in at 
least one dimension (longest diameter to be recorded) as > 20 mm with chest x-ray 
and as > 10 mm with CT scan, or clinical examination. Bone lesions are considered 
measurable only if assessed by CT scan and have an identifiable soft tissue 
component that meets these requirements (soft tissue component > 10 mm by CT 
scan). Malignant lymph nodes must be > 15mm in the short axis to be considered 
measurable; only the short axis will be measured and followed. All tumor 
measurements must be recorded in millimeters (or decimal fractions of centimeters). 
Previously irradiated lesions are not considered measurable unless progression has 
been documented in the lesion.
1.1.2
Non-Measurable Disease 
All other lesions (or sites of disease), including small lesions are considered non-
measurable disease. Bone lesions without a measurable soft tissue component, 
leptomeningeal disease, ascites, pleural/pericardial effusions, lymphangitis 
cutis/pulmonis, inflammatory breast disease, lymphangitic involvement of lung or 
skin and abdominal masses followed by clinical examination are all non-measurable. 
Lesions in previously irradiated areas are non-measurable, unless progression has 
been demonstrated.
1.1.3
Target Lesions 
When more than one measurable tumor lesion is present at baseline all lesions up to a
maximum of 5 lesions total (and a maximum of 2 lesions per organ) representative of 
all involved organs should be identified as target lesions and will be recorded and 
measured at baseline. 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. Note that pathological nodes must meet the criterion of a short axis of 
> 15 mm by CT scan and only the short axis of these nodes will contribute to the 
baseline sum. All other pathological nodes (those with short axis > 10 mm but < 15 
mm) should be considered non-target lesions. Nodes that have a short axis < 10 mm 
are considered non-pathological and should not be recorded or followed (see 10.2.4). 
At baseline, the sum of the target lesions (longest diameter of tumor lesions plus short 
axis of lymph nodes: overall maximum of 5) is to be recorded.

After baseline, a value should be provided on the CRF for all identified target lesions 
for each assessment, even if very small. If extremely small and faint lesions cannot be 
accurately measured but are deemed to be present, a default value of 5 mm may be 
used. If lesions are too small to measure and indeed are believed to be absent, a 
default value of 0 mm may be used.
1.1.4
Non-Target Lesions 
All non-measurable lesions (or sites of disease) plus any measurable lesions over and 
above those listed as target lesions are considered non-target lesions. Measurements 
are not required but these lesions should be noted at baseline and should be followed 
as “present” or “absent”.
1.1.5
Response 
All patients will have their BEST RESPONSE from the start of study treatment until 
the end of treatment classified as outlined below:
Complete Response (CR): disappearance of target and non-target. Pathological 
lymph nodes must have short axis measures < 10 mm (Note: continue to record the 
measurement even if < 10 mm and considered CR). Residual lesions (other than 
nodes < 10 mm) thought to be non-malignant should be further investigated (by 
cytology specialized imaging or other techniques as appropriate for individual cases 
(Eisenhauer, 2009)) before CR can be accepted. 
Partial Response (PR): at least a 30% decrease in the sum of measures (longest 
diameter for tumor lesions and short axis measure for nodes) of target lesions, taking 
as reference the baseline sum of diameters. Non-target lesions must be non-PD. 
Stable Disease (SD): neither sufficient shrinkage to qualify for PR, nor sufficient 
increase to qualify for PD taking as reference the smallest sum of diameters on study.
Progressive Disease (PD): at least a 20% increase in the sum of diameters of 
measured lesions taking as references the smallest sum of diameters recorded on 
study (including baseline) AND an absolute increase of > 5mm. Appearance of new 
lesions will also constitute progressive disease (including lesions in previously 
unassessed areas). For patients with on-study tumor assessments with questionable 
findings of new lesions, such as cases where it is possible that the lesions were 
present at baseline imaging albeit less visible, the patient may continue treatment (if 
patient is clinically doing well) for an additional 4-8 weeks, until the next scan which 
will either confirm presence of a new lesion finding or exclude it. In exceptional 
circumstances, unequivocal progression of non-target disease may be accepted as 
evidence of disease progression, where the overall tumor burden has increased 
sufficiently to merit discontinuation of treatment or where the tumor burden appears 
to have increased by at least 73% in volume. Modest increases in the size of one or 
more non-target lesions are NOT considered unequivocal progression. If the evidence

of PD is equivocal (target or non-target), treatment may continue until the next 
assessment, but if confirmed, the earlier date must be used.

Note:
Patients with a global deterioration of health status requiring discontinuation of treatment without radiological 
progression having been observed at that time should be reported as “symptomatic deterioration”. This is NOT 
objective PD. Every effort should be made to document the objective progression even after discontinuation of 
treatment.
1.2
Response Duration 
Response duration will be measured from the time measurement criteria for CR/PR 
(whichever is first recorded) are first met until the first date that recurrent or 
progressive disease is objectively documented, taking as reference the smallest 
measurements recorded on study (including baseline).
1.3
Stable Disease Duration 
Stable disease duration will be measured from the time of randomization until the 
criteria for progression are met, taking as reference the smallest sum on study 
(including baseline).
1.4
Methods of Measurement 


Protocol CanStem111P
Statistical Analysis Plan
BBI CONFIDENTIAL
Page 51
The same method of assessment and the same technique should be used to 
characterize each identified and reported lesion at baseline and during follow-up.
Assessments should be identified on a calendar schedule and should not be affected 
by delays in therapy. While on study, all lesions recorded at baseline should have 
their actual measurements recorded at each subsequent evaluation, even when very 
small (e.g. 2 mm). If it is the opinion of the radiologist that the lesion has likely 
disappeared, the measurement should be recorded as 0 mm. If the lesion is believed to 
be present and is faintly seen but too small to measure, a default value of 5 mm 
should be assigned. For lesions which fragment/split add together the longest 
diameters of the fragmented portions; for lesions which coalesce, measure the 
maximal longest diameter for the “merged lesion”.
Additionally, for optimal tumor assessment scanning options are listed below in the 
decreasing order of preference:
Order of 
Preference
Scanning Option
1
Chest-Abdomen-Pelvis CT with oral and I.V. contrast
2
Chest CT without I.V. contrast PLUS MRI Abdomen-Pelvis 
with oral and I.V. contrast1
3
Chest-Abdomen-Pelvis CT with oral contrast2
1
If Iodine contrast media is medically contraindicated.
2
If Iodine contrast media is medically contraindicated and MRI cannot be 
performed.
1.4.1
Clinical Lesions  
Clinical lesions will only be considered measurable when they are superficial and >
10 mm as assessed using callipers (e.g. skin nodules). For the case of skin lesions, 
documentation by colour photography including a ruler to estimate the size of the 
lesion is recommended. If feasible, imaging is preferred.
1.4.2
Chest X-ray 
Chest CT is preferred over chest X-ray, particularly when progression is an important 
endpoint, since CT is more sensitive than X-ray, particularly in identifying new 
lesions. However, lesions > 20 mm on chest X-ray may be considered measurable if 
they are clearly defined and surrounded by aerated lung. 
1.4.3
CT/MRI 
CT is the best currently available and reproducible method to measure lesions 
selected for response assessment. This guideline has defined measurability of lesions 
on CT scan based on the assumption that CT slice thickness is 5 mm or less. When 
CT scans have slice thickness greater than 5 mm, the minimum size for a measurable

Page 52
lesion should be twice the slice thickness. MRI is also acceptable in certain situations 
(e.g. for body scans). Other specialized imaging or other techniques may also be 
appropriate for individual case (Eisenhauer, 2009). For example, while PET scans are 
not considered adequate to measure lesions, PET-CT scans may be used providing 
that the measures are obtained from the CT scan and the CT scan is of identical 
diagnostic quality to a diagnostic CT (with IV and oral contrast).
1.4.4
Ultrasound 
Ultrasound is not useful in assessment of lesion size and should not be used as a 
method of measurement. If new lesions are identified by ultrasound in the course of 
the study, confirmation by CT is advised.
1.4.5
Endoscopy/Laparoscopy 
The utilization of these techniques for objective tumor evaluation is not advised. 
However, they can be useful to confirm complete pathological response when 
biopsies are obtained or to determine relapse in trials where recurrence following 
complete response or surgical resection is an endpoint. 
1.4.6
Histology 
These techniques can be used to differentiate between PR and CR in rare cases (for 
example, residual lesions in tumor types such as germ cell tumors, where known 
residual benign tumors can remain).
The cytological confirmation of the neoplastic origin of any effusion that appears or 
worsens during treatment when the measurable tumor has met criteria for response or 
stable disease is mandatory to differentiate between response or stable disease (an 
effusion may be a side effect of the treatment) and progressive disease.
