SYNOPSIS
Protocol Title: A Phase 1/2a Study of BMS-986242 Administered in Combination with 
Nivolumab (BMS-936558, Anti-PD-1) in Advanced Malignant Tumors
Study Phase:
Phase 1/2a
Rationale:
This study will consist of 2 parts, Part 1 Dose Escalation and Part 2 Dose-Expansion Cohorts.
During Part 1 the study will evaluate the safety, tolerability, pharmacokinetics (PK), and 
pharmacodynamics of escalating oral doses of BMS-986242 in combination with a flat dose of 
nivolumab. In addition, the study is expected to identify dose limiting toxicities (DLTs), the 
maximum tolerated dose (MTD) (or maximum administered dose [MAD]/alternative dose, if 
applicable) of BMS-986242 in combination with nivolumab in participants with advanced 
malignant tumors. The purpose of Part 2 of the study is to gather additional safety, tolerability, 
preliminary efficacy, PK, and pharmacodynamics information regarding BMS-986242 in 
combination with nivolumab.
Study Population:
Participants of at least 18 years of age with advanced malignant tumors.

Overall Design:
Part 1 open-label dose escalation and Part 2 dose-expansion cohort phase

To assess the short-term safety and clinical pharmacology profile of BMS-986242 
monotherapy prior to allowing participants to receive treatment in combination with nivolumab 
(see Section 3.1.2 for further details), dose escalation will start with a lead-in Cycle 0, whereby 
BMS-986242 is administered as monotherapy of 2-week duration in each dose escalation 
cohort. Decision to proceed to combination treatment with nivolumab (Cycle 1) for each 
participant in dose escalation will be determined after tolerability of the monotherapy lead-in 
is established in the 2-week Cycle 0 at each dose (see Section 5.1.2.1). The starting dose of 
BMS-986242 is 12.5 mg administered orally daily. Nivolumab will be administered at a dose 
of 480 mg intravenously (IV) Q4W. In the event the 12.5-mg dose level of BMS-986242 is 
determined to exceed the MTD in monotherapy or in combination with nivolumab, no lower 
BMS-986242 dose level will be further explored. At no point will the dose of BMS-986242 
administered in combination with nivolumab exceed doses of BMS-986242 that have been 
demonstrated previously to be safe in the monotherapy lead-in Cycle 0. In addition, a clinical 
pharmacology substudy will be conducted in which a single-dose PK, BMS-986242 exposure-
QTc relationship, and exploratory food effect of BMS-986242 will be assessed.

The study will be restricted to 6 disease types (melanoma, non-small cell lung cancer 
[NSCLC], squamous cell carcinoma of the head and neck [SCCHN], bladder urothelial 
carcinoma [BUC], renal cell carcinoma [RCC], and gastric cancer).

Upon completion of study treatment, participants will enter the Clinical/Safety Follow-up for 
at least 100 days (3 visits) after the last dose of study treatment.

After completion of the Clinical/Safety Follow-up period, participants will enter the 
Survival/Long-term Follow-up period, during which clinic visits or telephone contact every 
3 months will be performed to assess survival status up to 2 years from the last dose of study 
treatment.
Number of Participants: 
Up to 298 participants will be enrolled for this study; approximately 78 participants for Part 1 
(dose-escalation cohorts) and the clinical pharmacology substudy, and approximately 220
participants for Part 2 (dose-expansion cohorts).

Study Periods
Screening (up to 28 days):
Participants will sign informed consent and be evaluated for study eligibility.
Treatment Phase (consists of 104 weeks for all Parts):
In Part 1, the dose-escalation phase will start with Cycle 0, a lead-in period of 2 weeks in duration, 
during which monotherapy with BMS-986242 is administered (see Section 3.1.2 and Section 5.1.2
for further details). In both Part 1 and Part 2, each treatment cycle is 4 weeks (except Cycle 0) and 
is comprised of daily doses of BMS-986242 and 1 dose of nivolumab administered every 4 weeks 
on Day 1 of the treatment cycle. The total treatment period is 104 weeks or 26 cycles (excluding 
Cycle 0). Following every 2 treatment cycles (8 weeks), the decision to treat a participant with 
additional cycles of study treatment will be based on radiological tumor assessments (initial 
evaluation performed at baseline, end of Cycle 2, and every 8 weeks). Assessment of PR and CR 
must be confirmed at least 4 weeks following initial assessment. Tumor progression or response 
endpoints will be assessed using RECIST version 1.1 criteria for solid tumors.

Treatment beyond progression may be allowed in select participants
with initial 
RECIST v1-defined progressive disease (PD) after discussion and agreement with the BMS
Medical Monitor that the benefit/risk assessment favors continued administration of study 
treatment (eg, participants are continuing to experience clinical benefit as assessed by the 
investigator, tolerating treatment, and do not meet treatment discontinuation criteria). See Section 
5.1.2.3 for further details. 
Clinical/Safety Follow-up Period: 
Upon completion of study treatment, participants will enter the Clinical/Safety Follow-up period.
For participants who complete all scheduled cycles of study treatment, the End-of-Treatment 
(EOT) visit will be the same as the last scheduled and completed on-treatment visit, and the start 
of the Week 1 Clinical/Safety Follow-up visit. For participants who do not complete all scheduled 
cycles of study treatment, the EOT visit will be the most recent on-treatment visit (with all 
available safety and response data) and does not need to be repeated, and will be considered the 
start of the Week 1 Clinical/Safety Follow-up visit.
Participants who discontinue the treatment phase will enter the Clinical/Safety Follow-up period. 
Participants must be followed for at least 100 days (representing approximately 5 half-lives for 
nivolumab) after the last dose of study treatment. Follow-up visits should occur at Days 30, 60, 
and 100 (±10 days) after the last dose of study treatment or coinciding with the date of 
discontinuation (±10 days) if the date of discontinuation is greater than 30 days after the last dose 
of study treatment to monitor for adverse events.
Participants will be required to complete 3 Clinical/Safety Follow-up visits regardless of whether 
they start new anti-cancer therapy, except those participants who withdraw consent for study 
participation.
Survival/Long-term Follow-up: 
After completion of the Clinical/Safety Follow-up period, participants will then enter the 
Survival/Long-term Follow-up period. During this period, clinic visits or telephone contact every 
3 months will be performed to assess survival status. The duration of Survival/Long-term 
Follow-up period will be 2 years from the last dose of study treatment.
Duration of Study: 
The total duration of the study is expected to be approximately 5 years from the onset of the first 
visit of the first subject to the required Survival/Long-term Follow-up of the last subject enrolled.

INTRODUCTION
This is a dose-escalation and dose-expansion cohort study of BMS-986242, a small molecule 
inhibitor of the indoleamine 2,3-dioxygenase 1 (IDO1) enzyme, in combination with nivolumab 
(anti-programmed cell death-1 [PD-1]), in humans with advanced malignant tumors. This study 
will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary 
efficacy of escalating oral doses of BMS-986242 in combination with a flat dose of nivolumab. In 
addition, the study is expected to identify the maximum tolerated dose (MTD)/recommended 
Phase 2 dose of BMS-986242 in combination with nivolumab to be used in the dose-expansion 
cohort phase. Part 2 (dose-expansion cohorts) will assess the preliminary efficacy of BMS-986242 
in combination with nivolumab in specific malignant disease populations and will also serve to 
generate further data to support dose optimization of the combination. The study also includes a 
clinical pharmacology substudy designed to evaluate the PK of a single dose of BMS-986242, 
exposure-QTc relationship, and the effect of food on the bioavailability of BMS-986242.

Overall Benefit/Risk Assessment
3.3.1
Risk/Benefit for BMS-986242
There is no prior human experience with BMS-986242; therefore, clinical benefit has not been 
assessed in participants with advanced cancer. Other IDO1 inhibitors have entered human trials, 
both as monotherapy and in combination with other anti-cancer treatments (epacadostat from 
Incyte Corporation, GDC-0919 from Roche, indoximod from NewLink Genetics, and 
BMS-986205, from Bristol-Myers Squibb). Published safety information for epacadostat shows a 
favorable safety profile as monotherapy (ie, well tolerated across all dose levels, with the most 
common AEs being Grade 1 or 2 fatigue and gastrointestinal disturbances)19, suggesting no 
intrinsic risk of suggesting no intrinsic risk of severe toxicity with IDO1 blockade. The assessment 
of potential clinical benefit of BMS-986242 is based upon preclinical human xenograft model 
SKOV3, in which significant IDO1 inhibition was achieved.
In the absence of clinical studies, the assessment of the risk of side effects of BMS-986242 in 
clinical trials is based upon data from nonclinical toxicology studies in rats and dogs. In rats, 
multiple doses up to 10 mg/kg/day were well-tolerated, while single doses 20 mg/kg resulted in 
overt CNS toxicity. In dogs, the top dose studied exceeded the MTD. Clinical signs included 
vomiting, diarrhea, dehydration, and weight loss. Chronic inflammation was noted in the 
gallbladder at 100 mg/kg/day and corresponded with increases in serum GGT and ALT activity. 
The gallbladder inflammation and serum chemistry changes were reversible. CNS and respiratory 
safety pharmacology assessments were conducted as part of the pivotal 1-month oral toxicity 
studies in rats and dogs. There were no BMS-986242-related CNS signs or effects on cranial or 
spinal nerve function or respiratory function at doses up to 10 mg/kg/day in rats and up to 
100 mg/kg/day in dogs.
The nonclinical toxicity profile was used to determine the human starting dose and to develop 
appropriate exclusion criteria and safety monitoring for this study. Complete blood counts and 
chemistry test results (including liver and kidney functions) will be assessed weekly during 
monotherapy and Cycle 1 of combination and every 4 weeks (Q4W) thereafter. In addition, 
complete physical examinations (PEs) will be conducted on Day 1 of each cycle, with additional 
symptom-directed PEs at least weekly during monotherapy and Q2W for the first 12 weeks during 
combination. Participants with viral hepatitis or other liver disease, such as nonalcoholic fatty liver 
disease, will be excluded to minimize the potential for hepatotoxicity. Assays for cardiac ion 
channels did not indicate a potential for cardiovascular liability. Nevertheless, participants with 
QTc prolongation at baseline will be excluded, medications known to cause prolonged QT will be 
prohibited, and electrocardiograms (ECGs) will be monitored during the study. 
Continuous safety assessments will be utilized by the investigators and Sponsor to determine 
whether dose modification, additional safety measures, or termination of the study is required at 
any time. In addition, AEs and serious adverse events (SAEs) will be reviewed on an ongoing basis 
by the Sponsor’s Medical Monitor and Global Pharmacovigilance and Epidemiology 
representatives to monitor for any safety signals or trends.

BMS-986242
IDO1 INHIBITOR
As BMS-986242 is an experimental agent, it is possible that unforeseen, unknown, or 
unanticipated reactions may occur. Based on the nonclinical safety profile of BMS-986242, and 
with a 60-fold safety margin built into the planned starting dose of 25 mg daily, the potential safety 
risks are expected to be minimized. Taking a conservative approach, an initial 12.5 mg starting 
dose will be used (see Section 5.5.1). A Bayesian Logistic Regression Method (BLRM) with 
overdose control principle will be employed to ensure that safety is not compromised during dose 
escalation. This method limits the risk of exposing participants in the next cohort to an unsafe or 
toxic dose. 
3.3.2
Risk/Benefit for Combination with Nivolumab 
Nivolumab has demonstrated clinical activity in patients with advanced NSCLC, RCC, melanoma, 
and lymphomas, as well as other tumors. While preclinical testing of IDO1 inhibitors does not 
suggest that IDO inhibition alone will bring benefit to patients, it is hypothesized that inhibition 
of IDO1 will relieve the immunosuppressive milieu within the tumor, thus allowing greater depth 
of response and ultimately improved survival benefit of other therapies. Early clinical data from a 
trial of epacadostat in combination with pembrolizumab (a PD-1 inhibitor) is suggestive of the 
potential synergy between these mechanisms. The largest cohort of participants in this study was 
melanoma, in which there were 54 evaluable participants. Thirty (30) of these participants were 
responders, including 8 CRs and 22 PRs, for an ORR of 56%.43 Per the United States Prescribing 
Information for pembrolizumab, the ORR for monotherapy in advanced melanoma is 34%.
Similarly, epacadostat plus nivolumab in 40 patients with melanoma yielded an ORR of 63%.44  
In several other tumor types epacadostat combined with pembrolizumab also showed high ORRs: 
NSCLC 35% (n=40), bladder cancer 35% (n=37), SCCHN 31% (n=36), and RCC 30% (n=30).45
As a reference from the pembrolizumab prescribing information, pembrolizumab ORRs are 18%
(PD-L1 Tumor Proportion Score [TPS] ≥1% subset, n=344) for NSCLC, 21% (n=270) for bladder 
cancer, and 16% (n=174) for SCCHN. While these are different studies with slightly different 
patient populations, the data suggest that IDO1 inhibition has the potential to improve ORRs in 
tumor types that respond to PD-1 inhibition.
Nivolumab has demonstrated a manageable safety profile. Nivolumab is indicated as monotherapy 
in patients with BRAF V600 wild-type and BRAF V600 mutation-positive unresectable or 
metastatic melanoma. Nivolumab in combination with ipilimumab is indicated in patients with 
unresectable or metastatic melanoma. Nivolumab is also indicated in patients with metastatic 
NSCLC and progression on or after platinum-based chemotherapy, in patients with advanced RCC 
who have received prior antiangiogenic therapy, in adult patients with classical Hodgkin 
lymphoma that has relapsed or progressed, in patients with recurrent or metastatic SCCHN with 
disease progression on or after a platinum-based therapy; in patients with locally advanced or 
metastatic urothelial carcinoma, in adult and pediatric (12 years and older) patients with 
microsatellite instability-high or mismatch repair deficient metastatic colorectal cancer that has 
progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan.
The overall safety experience, when used either as a monotherapy or in combination with another 
therapeutic, is based on experience in approximately 12,300 participants treated to date. There is

no pattern in the incidence, severity, or causality of AEs to nivolumab dose level. The most 
common AEs include fatigue, rash, pruritus, diarrhea, and nausea. Side effects of nivolumab 
therapy may include those associated with immune-mediated activation, such as pneumonitis, 
thyroiditis, and hepatitis. Most of these events resolved with immune-modulating medication. To 
mitigate risk from serious immune-mediated AEs, participant management algorithms for 
nivolumab-related AEs from prior collective nivolumab experience have been included. In 
addition, participants will have to meet a set of safety criteria in order to continue from 
monotherapy to combination treatment so that the risk of cumulative toxicity is minimized (see 
Section 5.1.2.1).
In addition, significant clinical data indicates that IDO1 inhibitors can be combined safely with 
nivolumab. Epacadostat was combined with nivolumab in 36 patients during a dose-escalation 
study with no occurrence of DLTs and in 230 additional patients in dose-expansion cohorts with 
an acceptable safety profile.44 Similarly, BMS-986205 was combined with nivolumab and 
administered to 44 patients during a dose-escalation study with DLTs occurring in 1 out of 9
participants at a dose of 100 mg QD (autoimmune hepatitis, which could be caused by PD-1 
inhibition alone) and in 1 out of 10 participants at a dose of 200 mg QD (anemia), as reported at 
the annual meeting of the American Association for Cancer Research (AACR) 2017. 46 Subsequent 
to this report, 200 mg QD BMS-986205 was determined to be the MTD, and 100 mg QD is being 
studied in Phase 2 cohorts (preliminary unpublished data).

Summary
Despite innovations in cancer treatment, alternative therapies are needed for participants with 
advanced cancer that has progressed or not responded to other treatments. The emerging role of 
combination immune-modulating therapies in producing deep and durable responses in a variety 
of tumor types suggests that once a pharmacologically-active dose range is reached, there may be 
a potential benefit of IDO inhibition with BMS-986242 for participants when used in combination 
with nivolumab. Preclinical safety signals were monitorable and reversible and are to be closely 
monitored in this study. This supports the evaluation of BMS-986242 as monotherapy and in 
combination with nivolumab in participants with advanced cancer who have few treatment options.

STUDY DESIGN
5.1
Overall Design
This is a Phase 1/2a, open-label study of BMS-986242 administered as a single agent and in 
combination with nivolumab in participants with advanced malignant tumors. The study will be 
conducted in 2 parts, dose escalation (Part 1) and dose-expansion cohorts (Part 2). In addition, a 
clinical pharmacology substudy will be conducted in which BMS-986242 single-dose PK, 
exposure-QTc relationship and exploratory food effect on BMS-986242 bioavailability will be 
assessed.
Dose escalation (Part 1) will start with a lead-in Cycle 0 (see Section 3.1.2 for details on lead-in
rationale), whereby BMS-986242 is administered as monotherapy of 2-week duration in each 
dose-escalation cohort. The decision to proceed to combination treatment with nivolumab 
(Cycle 1) for each participant in dose escalation will be determined after tolerability of the 
monotherapy lead-in is established in the 2-week Cycle 0 at each dose (see Section 5.1.2.1). The 
starting dose of BMS-986242 is 12.5 mg administered orally daily. Nivolumab will be 
administered IV at a dose of 480 mg Q4W. In the event the 12.5-mg dose level of BMS-986242 is
determined to exceed the MTD in monotherapy or in combination with nivolumab, no lower BMS-
986242 dose level will be further explored.. Please refer to Appendix 7.
Dose escalation may be stopped prior to reaching the MTD if pharmacodynamic data indicate that 
maximum inhibition of IDO1 has been achieved. In such a case, the MAD or an alternate dose

below the MAD will be used for the expansion cohorts. At no point will the dose of BMS-986242
administered in combination with nivolumab exceed doses of BMS-986242 that have been 
demonstrated previously to be safe in the monotherapy lead-in Cycle 0 (Section 5.1.2.1).
Participants will be enrolled per inclusion criteria in Section 6.1.
Cycle 0: Each dose-escalation cohort will start with Cycle 0, which is a 2-week BMS-986242
monotherapy lead-in. If there are no dose-limiting toxicities (DLTs) (see Section 7.4.1), 
participants will proceed to receive the combination of nivolumab and BMS-986242 (Cycle 1). 
Dose-expansion cohorts will be carried out at the dose of BMS-986242 selected from dose 
escalation in combination with nivolumab 480 mg and may represent the MTD, maximum 
administered dose (MAD), or an alternate dose for the combination. Study therapy consisting of 
BMS-986242 daily and nivolumab Q4W will be administered in 4-week cycles for up to 26 cycles. 
Participants in 6 disease-restricted populations will be enrolled as follows: melanoma, NSCLC, 
SCCHN, BUC, RCC, and gastric cancer. The dose(s) selected for cohort expansion will not exceed 
the MTD or MAD determined in dose escalation.
Participants will complete up to 4 phases of the study: Screening, Treatment, Clinical/Safety 
Follow-up, and Survival/Long-term Follow-up, as described below. The study design schematic 
is presented in Figure 5.1-1.

5.1.1
Screening Phase
The screening phase will last for up to 28 days. The screening phase begins by establishing the 
participant’s initial eligibility and signing of the informed consent form (ICF). Participants will be 
enrolled using the Interactive Response Technology (IRT).
If a participant surpasses the 28-day window during the screening phase because of a study-related 
procedure (eg, scheduling of a tumor biopsy or waiting time for a study-related laboratory value),

the participant must be re-consented but does not need to be assigned a new participant
identification number. In this situation, the least amount of repeat procedures from the initial 
screening to qualify the participant while maintaining safety and eligibility under the discretion of 
the BMS Medical Monitor and investigator may be done to reduce any undue burden of procedure 
in this population.
5.1.2
Treatment Phase
The treatment phase consists of up to twenty-six 4-week treatment cycles. Each treatment cycle is 
comprised of a daily oral dose of BMS-986242 and 1 dose of nivolumab administered IV Q4W on 
Day 1 of the treatment cycle. In addition, dose escalation will start with Cycle 0, a lead-in period 
of 2-week duration, during which monotherapy with BMS-986242 is administered. The total 
treatment period is 104 weeks or 26 cycles. This is in addition to the 2-week Cycle 0.
Following every 2 treatment cycles (8 weeks), the decision to treat a participant with additional 
cycles of study treatment will be based on radiological tumor assessments (initial evaluation 
performed at baseline, end of Cycle 2, and every 8 weeks). Assessments of partial response (PR) 
and complete response (CR) must be confirmed at least 4 weeks following initial assessment. 
Tumor progression or response endpoints will be assessed using Response Evaluation Criteria in 
Solid Tumors (RECIST) v1.1 criteria for solid tumors (Appendix 6). 
Treatment beyond progression may be allowed in select participants
with initial 
RECIST v1.1-defined progressive disease (PD) after discussion and agreement with the BMS 
Medical Monitor that the benefit/risk assessment favors continued administration of study 
treatment (eg, participants are continuing to experience clinical benefit as assessed by the 
investigator, tolerating treatment, and meeting other criteria specified in Section 5.1.2.3).
Participants with a response of stable disease (SD), PR, or CR at the end of a given cycle will 
continue to the next treatment cycle. Participants will generally be allowed to continue study 
treatment until the first occurrence of either: 1) completion of the maximum number of cycles,
2) PD, 3) clinical deterioration suggesting that no further benefit from treatment is likely,
4) intolerability to study treatment, or 5) the participant meets criteria for discontinuation of study 
treatment as outlined in protocol Section 8. Individual participants with confirmed CR will be 
given the option to discontinue study treatment on a case-by-case basis after specific consultation 
and agreement between the investigator and BMS Medical Monitor in settings where benefit/risk 
justifies discontinuation of study treatment. 
5.1.2.1
Part 1: Dose Escalation
Six disease-restricted populations will be included in the dose-escalation part. These are 
melanoma, NSCLC, SCCHN, RCC, BUC, and gastric cancer. The dose-escalation part of the study 
will evaluate doses of BMS-986242 in combination with nivolumab based on DLTs using a BLRM 
model (for BMS-986242 monotherapy lead-in) and BLRM-copula model (for BMS-986242 in 
combination with nivolumab). The Bayesian models will be used for recommendation of the next 
dose to be investigated. BLRM (combined with copula) framework with an escalation with 
overdose control principle will be employed to ensure that safety is not compromised during dose 
escalation.

IDO1 INHIBITOR
The initial dose level of BMS-986242 will be 12.5 mg administered orally daily. After a 2-week 
period, once initial lead-in monotherapy (Cycle 0) is deemed tolerable, combination with 480 mg 
flat dose nivolumab (Cycle 1) will be initiated. 
Dose levels to be considered for the next combination cohort (with monotherapy lead-in) will be 
based on recommended monotherapy dose from BLRM and recommended combination dose from 
BLRM-copula. The lower dose from these 2 recommendations will be considered. Potential dose 
levels for dose escalation are provided in Table 5.1.2.1-1. The maximum allowable increase in 
dose will be 100%. Final dose selection for the next cohort/dose level will be made in conjunction 
with all data available from PK and pharmacodynamic assessments, and will be made after 
discussion and agreement between investigators and BMS Medical Monitor. Accordingly, 
intermediate or lower doses, or less frequent dosing of BMS-986242 may be tested if none of the 
planned doses/schedules are found to be tolerated as the lead-in phase or in combination with 
nivolumab.
Initially, approximately 4 participants will be treated at the starting dose level of BMS-986242. 
During the dose-escalation phase, once a dose level has been decided, a set of approximately 4
participants will be initially treated at that specified dose level. Increments of approximately 
3 participants will be added to each dose level depending on model recommendation and clinical 
judgment. Due to the potential for early discontinuation, additional participant(s) may be enrolled 
to ensure at least 3 evaluable participants at each dose level. 
Cohort tolerability assessment and subsequent dose recommendation may occur when 2 
DLT-evaluable participants within a cohort have completed the 6-week DLT observation period 
(see Section 7.4.1 for criteria for DLTs). DLTs occurring within the 2-week lead-in period (DLT 
observation period for monotherapy) will be used to fit the BLRM model for monotherapy. DLTs 
occurring within the 4 weeks of combination period (DLT observation period for combination) 
will be used to fit the BLRM-copula model. If a potential DLT occurring in any third evaluable 
participant does not influence the dose recommendation by BLRM (-copula), then the BLRM 
(-copula)-recommended next dose level may proceed without waiting for the third participant to 
complete the corresponding DLT observation period after discussion and agreement by the sponsor 
and investigators. The lower recommended dose from both models will be considered for the next 
dose escalation. Participants receiving 75% (11 out of 14 doses) of BMS-986242 in the 2-week 
lead-in cycle will be considered as DLT-evaluable participants for BMS-986242 monotherapy. 
Participants who receive at least 1 dose of nivolumab and have been followed at least 5 days and 
receive 75% BMS-986242 (21 out of 28 doses) in the 4-week DLT observation period for 
combination therapy will be considered as DLT-evaluable participants. Continuous re-assessment 
of dose recommendation by BLRM will be carried out at each dose level after each cohort of 
participants with consideration of all available DLT information. In order to allow additional 
safety, PK, and pharmacodynamic assessment, in Part 1 up to 12 additional participants may be 
enrolled at any dose level at or below the MTD, up to a total of 24 additional participants.
No intra-participant dose escalation is allowed, although dose modifications of BMS-986242 may 
be permitted (see Table 7.4.2-1).

Sentinel Participant: During dose escalation, a staggered dosing (sentinel participant) approach 
will be used. In the first dose level, the first participant in both lead-in and combination will receive 
the Cycle 0 Day 1 or Cycle 1 Day 1 dose(s) of study treatment(s) and be observed for 5 days before 
additional participants in that cohort receive monotherapy or combination study treatment. In 
subsequent dose levels, a sentinel participant with a 5 day observation period will be used for 
Cycle 0 Day 1.

Clinical Pharmacology Substudy: 
A clinical pharmacology substudy will be conducted to characterize the PK profile of 
BMS-986242 after a single-dose administration, BMS-986242 exposure-QTc relationship and to 
evaluate of the effect of food on the bioavailability of BMS-986242. The substudy will evaluate 
selected dose levels that have already been determined to be tolerable during dose escalation.
Participants in the substudy will receive a single dose of BMS-986242 under fasting condition on 
Cycle 00 (Day 1) followed by a 7-day washout period during which serial PK samples will be 
collected (Table 9.5.3-2). Triplicate ECGs will be collected at predose and select time points 
postdose on Day 1 (with matching PK samples) to allow the assessment of the effect of 
BMS-986242 exposure on QTc intervals. All participants will then receive BMS-986242 under 
the usual dosing condition with a light meal once daily in combination with nivolumab on Cycle 1 
Day 1 and will follow all assessments as per Table 2-3. The inclusion criteria used in the dose-
escalation phase apply to participants enrolled in the clinical pharmacology substudy (Section 6.1). 
The doses to be evaluated in the substudy will be determined based on available safety, PK and
biomarker data. At least 3 doses (below, at, and above the expected dose for expansion) are 
expected to be evaluated in at least 6 evaluable participants per dose level in the substudy. 
Additional dose levels at may be evaluated if warranted.

At a designated dose level, an exploratory food effect evaluation will be conducted. After receiving
a single dose of BMS-986242 under fasting condition on Cycle 00 (Day 1) followed by a 7-day 
washout period, participants will receive 1 dose of BMS-986242 with a high-fat meal on Day 8. 
Serial PK samples will be collected during a 2-Day washout period (Table 9.5.3-2). Participants 
will then receive BMS-986242 under the usual dosing condition with a light meal once daily in 
combination with nivolumab on Cycle 1 Day 1 and will follow all assessments as per Table 2-3. 
For the dose to be evaluated in the food effect substudy, either a higher dose would need to be 
demonstrated to be safe in the dose-escalation phase or sufficient exposure multiples should have 
been obtained following multiple doses at the same dose level. Additional doses may be evaluated 
if warranted.

Part 2: Dose-Expansion Cohorts
The purpose of cohort expansion is to gather additional safety, tolerability, preliminary efficacy, 
PK, and pharmacodynamic information regarding BMS-986242 in combination with nivolumab.
Six disease-restricted populations will be included in the dose-expansion cohort phase. These are 
melanoma, NSCLC, SCCHN, RCC, BUC, and gastric cancer. PD-(L)1 inhibitors are an approved 
treatment option for melanoma, NSCLC, SCCHN, RCC, and BUC, and prior treatment may 
impact preliminary efficacy; thus separate cohorts (PD-(L)1 inhibitor naive or experienced) will 
be enrolled for these 5 tumor types. Approximately 20 participants will be included in each dose-
expansion cohort, for a total of approximately 220 participants in Part 2.
Continuous evaluation of toxicity events in the cohort expansions will be performed throughout 
enrollment in the expansion cohorts. If, at any time, the aggregate rate of treatment-related 
toxicities meeting DLT criteria exceeds 33% across all participants treated in cohort expansions, 
the findings will be discussed and further enrollment may be interrupted. Depending on the nature 
and grade of the toxicity and after assessing the risk/benefit ratio, a new dose(s) for all cohorts 
may be initiated at a previously tested lower dose level or at a dose level intermediate to previously 
tested lower dose levels.
5.1.2.3
Treatment Beyond Progression
A subset of participants with solid tumors treated with immunotherapy may derive clinical benefit 
despite initial evidence of PD. Participants will be permitted to continue on treatment beyond 
initial RECIST v1.1-defined PD (see Appendix 6) as long as they meet the following criteria:

Investigator-assessed clinical benefit and not having rapid disease progression

Absence of signs or symptoms indicating disease progression

Continue to meet all other study protocol eligibility criteria

Tolerance of study treatment

Stable performance status

Treatment beyond progression will not delay an imminent intervention to prevent serious 
complications of disease progression (eg, CNS metastases)

Participant provides written informed consent prior to receiving additional nivolumab and
BMS-986242 treatment, using an ICF describing any reasonably foreseeable risks or 
discomforts or other alternative treatment options
The assessment of clinical benefit should take into account whether the participant is clinically 
deteriorating and unlikely to receive further benefit from continued treatment. All decisions to 
continue treatment beyond initial progression must be discussed with the BMS Medical Monitor,
and an assessment of the benefit/risk of continuing with study treatment must be documented in 
the study records. Participants will be re-consented to explain the rationale for this ongoing 
treatment.
Participants should continue to receive monitoring according to the on-treatment assessments in 
Section 9.4. Radiographic assessment by computed tomography (CT; preferred) or magnetic 
resonance imaging (MRI) described in Section 2 and in Section 9.1.1 is required when participants

continue post-progression treatment. For participants who discontinue post-progression treatment 
with study treatment, no additional radiographic assessments will be required.
5.1.2.4
Discontinuation Due to Further Progression
Participants should discontinue study treatment upon further evidence of further progression, 
defined as an additional 10% or greater increase in tumor burden volume from time of initial 
progression (including all target lesions and new measurable lesions).
The tumor burden volume from time of initial progression should be used as the reference baseline 
for comparison with the post-progression assessment.
Any new lesion considered non-measurable at the time of initial progression may become 
measurable and, therefore, must be included in the tumor burden measurement as follows:
For solid tumors: New lesions are considered measurable at the time of initial progression if the 
longest diameter is at least 10 mm (except for pathological lymph nodes, which must have a short 
axis of at least 15 mm).
For statistical analyses that include the investigator-assessed progression date, participants who 
continue treatment beyond initial investigator-assessed, RECIST v1.1 -defined progression will be 
considered to have investigator-assessed PD at the time of the initial progression event.
5.1.3
Clinical/Safety Follow-up
Upon completion of study treatment, participants will enter the Clinical/Safety Follow-up period 
(refer to Section 5.3 and Section 5.1.4 for definitions for end of treatment [EOT]). 
Participants must be followed for at least 100 days after the last dose of study treatment. Follow-up 
visits should occur at Days 30, 60, and 100 (10 days) after the last dose of study treatment or 
should coincide with the date of discontinuation (10 days) if date of discontinuation is greater 
than 30 days after the last dose of study treatment to monitor for AEs. Participants will be required 
to complete 3 Clinical/Safety Follow-up visits regardless of whether they start a new anti-cancer
therapy, except those participants who withdraw consent for study participation.
5.1.4
Survival/Long-Term/Response Follow-up
After completion of the Clinical/Safety Follow-up period, all participants will then enter the 
Survival/Long-term Follow-up period. During this period, clinic visits or telephone contact every 
3 months will be performed to assess survival status. The duration of Survival/Long-term 
Follow-up period will be 2 years from the last dose of study treatment.
After completion of the Safety Follow-up period, participants who discontinue study with ongoing 
SD, PR, or CR at the EOT visit will enter the Response Follow-up period. These periods will occur 
simultaneously with the Survival Follow-up period for mentioned participants. During the 
Response Follow-up period (or until disease progression or withdrawal of study), these participants
will continue to have radiological and clinical tumor assessments every 12 weeks for the first year 
after the EOT visit and then every 6 months thereafter up to 2 years from the last dose of study 
treatment. Radiological tumor assessments for participants who have ongoing clinical benefit may 
continue to be collected after participants complete the survival phase of the study.

Data Monitoring Committee and Other External Committees
BMS has elected not to use a Data Monitoring Committee for this study. In addition to the 
comprehensive safety monitoring plan outlined below, the following key points were considered 
for this decision:

This is an open-label study.

The eligibility criteria exclude participants with disease characteristics that could predispose
to higher risk of morbidity, eg, uncontrolled or significant cardiovascular disease, etc. 

Exclusion of participants with active, known, or suspected autoimmune disease also applies,
as they could be at risk for exacerbation of their condition by the administration of therapies 
that relieve immune suppression such as BMS-986242 and nivolumab.

Participants will be observed frequently for clinical evaluation and blood counts during dose 
escalation.

Well-defined discontinuation criteria are established in the protocol for individual participants 
for both safety and treatment futility with clear criteria for treatment discontinuation, dose 
delay, and toxicity management.
BMS has in place a multi-layered process for ensuring patient safety through close collaboration 
of study site investigators, the BMS study team, and the BMS GPVE-led Medical Surveillance 
Team (MST). This collaborative process constitutes the Data Safety Monitoring Plan for the study 
as detailed below:
Study safety is evaluated continuously by representatives of BMS GPVE, who operate 
independently from the clinical team and monitor safety across all BMS protocols. AEs are 
monitored continuously by GPVE. Signal detection is performed at least monthly and ad hoc 
throughout the study by the MST composed, at a minimum, of the GPVE medical safety 
assessment physician (Chairman of the MST) and GPVE single case review physician, the study 
Medical Monitor(s), the study biostatistician, and epidemiologist. The MST monitors actual or 
potential issues related to patient safety that could result in a significant change in the medical 
risk-benefit balance associated with the use of study treatments. Furthermore, investigators will be 
kept updated of important safety information, such as DLTs, during teleconferences between 
investigators and the BMS clinical team that will be held at least Q4W during dose escalation and 
at least monthly during cohort expansion. If appropriate, select safety issues may be escalated to a 
senior-level, multidisciplinary, BMS-wide Medical Review Group for further evaluation and 
action.
To support safety oversight, BMS has established ongoing processes for collection, review, 
analysis, and submission of individual AE reports and their aggregate analyses. Because this is an 
open-label study, the BMS Medical Monitor and the investigators will have access to all data 
necessary for safety evaluation.

Fasting Treatment: Following an overnight fast of at least 10 hours, participants should be 
administered BMS-986242 with approximately 240 mL of water. No food should be allowed for 
at least 4 hours postdose. Water is allowed ad libitum except for 1 hour before and 1 hour after 
drug administration.
High-fat Meal Treatments: Following an overnight fast of at least 10 hours, participants will start 
the recommended meal 30 minutes prior to administration of BMS-986242. Study participants 
should eat this meal within 30 minutes or less; however, BMS-986242 should be administered 
30 minutes after the start of the meal. BMS-986242 should be administered with approximately 
240 mL of water. No food should be allowed for at least 4 hours postdose. Water is allowed ad 
libitum except for 1 hour before and 1 hour after drug administration.
A high-fat (approximately 50% of total caloric content of the meal) and high-calorie

Nivolumab (Part 1 and Part 2)
During combination treatment, infusion of nivolumab should start approximately 30 minutes 
following BMS-986242. Nivolumab should be infused over 30 minutes. Further details regarding 
preparation and administration will be provided separately in site/pharmacy training materials. 
Nivolumab will be administered IV as a flat dose. There will be no dose escalations or reductions 
of nivolumab allowed once assigned. There are no premedications recommended for nivolumab 
on the first cycle. If an acute infusion reaction is noted, participants should be managed according 
to Section 7.7.1.5.
7.2
Method of Treatment Assignment
During the screening visit, the investigative site will call into the enrollment option of the IRT
designated by BMS for assignment of a 5-digit participant number that will be unique across all 
sites. Enrolled participants, including those not dosed, will be assigned sequential participant
numbers starting with 00001 (eg, 00001, 00002, 00003… 00010). The participant identification 
number will ultimately be composed of the site number and participant number. For example, the 
first participant screened (ie, enrolled) at site number 1 will have a participant identification 
number of 0001 00001. Once it is determined that the participant meets the eligibility criteria 
following the screening visit, the investigator site will call the IRT within 3 days prior to the first 
study treatment administration for the participant to be assigned to a treatment group.

Dosage Modification
7.4.1
Dose-limiting Toxicity
For the purpose of guiding dose escalation, DLTs will be defined based on the incidence and grade 
of AEs for which no alternate cause can be identified. 
Part 1: Cycle 0 BMS-986242 (monotherapy lead-in) will have a 2-week DLT evaluation period 
(DLT1). The combination regimen will have 4-week DLT evaluation period (DLT2). Therefore, 
the total DLT assessment period is 6 weeks. Participants may proceed from Cycle 0 to Cycle 1 at 
each cohort unless any of the following events is observed: any DLT, Grade 2 or higher immune-
related AEs considered related to BMS-986242 (eg, immune-mediated pneumonitis, colitis, 
hepatitis, nephritis, renal dysfunction) with the exception of immune-mediated hypothyroidism 
and hyperthyroidism, or Grade 2 AST and ALT elevation that does not resolve to Grade 1 within 
1 week. For Grade 2 AST and ALT elevations that resolve to Grade 1 or baseline within 1 week, 
participants can be rechallenged with BMS-986242 monotherapy for a minimum of 5 days before 
proceeding to combination with nivolumab provided there is not a recurrence of Grade 2 event.
The total DLT period is 6 weeks, and participants must have received at least 75% of the 
BMS-986242 doses and 1 dose of nivolumab with observation for a minimum of 21 days following 
the first combination treatment dose to be considered evaluable for dose escalation decisions. 
Based on the predicted human half-life of BMS-986242 of 13 hours, this interval is expected to 
cover the anticipated timeframe for the occurrence of clinically significant immediate and early-
onset AEs related to BMS-986242 monotherapy during Cycle 0 and repeat dosing of BMS-986242 
in combination with nivolumab in Cycle 1. 
The incidence of DLTs that occur within 6 weeks following the start of study treatment will guide 
dose escalation decisions. AEs will be graded according to the NCI CTCAE v4.03. For the 
purposes of participant management, study treatment-related AEs occurring at any time that meet 
the DLT definition will lead to dose interruption, dose modifications, and/or permanent 
discontinuation of study treatment as defined in Section 8. Participants who withdraw from the 
study during the DLT evaluation interval for reasons other than a DLT may be replaced at the same 
dose level. The incidence of DLT(s) during the first cycle of treatment (the DLT evaluation period) 
will be used in dose escalation decisions and to define the MTD. AEs occurring after the DLT 
period will be considered for the purposes of defining the MTD, upon agreement between the 
Sponsor/Medical Monitor and investigators, if they are determined to have no clear alternative 
cause and are not related to disease progression.
For the purpose of guiding dose escalation, DLTs are defined below based on the incidence and 
grade of AEs for which no alternate cause can be identified.

In addition to the above criteria, any toxicity that results in a participant not receiving at 
least 75% of the doses of BMS-986242 and the dose of nivolumab during the DLT evaluation 
period or causing greater than 2 weeks of dose delay will be classified as a DLT. 
7.4.2
Guidelines for Dose Modification
Participants will be monitored continuously for AEs while on study treatment. Participants will be 
instructed to notify their physician immediately for any and all AEs. The criteria presented in this 
section and Table 7.4.2-1 for dose modifications for BMS-986242 and delays are meant as general 
guidelines.
Participants will continue to receive study treatment as long as they have not had disease 
progression or study treatment-related AEs requiring dose modification as described below.

Dose modification, interruption, or delay may occur in the setting of a lower-grade AE and/or 
be more conservative than indicated in Table 7.4.2-1 based on the clinical judgment of the 
investigator and in consultation with the Sponsor/Medical Monitor.

Dose reductions of BMS-986242 should be to the previous lower dose level.

If several AEs of varying grades or severities occur simultaneously, the dose modification 
applied should be the greatest reduction applicable.

Assessment of causality (chronology, confounding factors such as disease, concomitant 
medications, diagnostic tests, and previous experience with the agent) must be determined and 
documented by the investigator prior to dose modification.

If the same AE recurs despite a dose reduction, a second dose reduction versus discontinuation 
of BMS-986242 will be discussed and agreed upon by the Sponsor/Medical Monitor and 
investigators.

No more than 2 dose reductions of BMS-986242 will be allowed per participant. If a third dose 
reduction is required, the participant must discontinue BMS-986242. Dose re-escalation after 
a dose reduction may occur in limited circumstances (such as a change in attribution of an AE) 
after discussion and agreement of the Sponsor/Medical Monitor and investigators.

Skipped doses will not be administered within the same cycle.

For an AE requiring dose modification, BMS-986242 and nivolumab should be interrupted to 
allow recovery from the AE. Re-initiation of study treatment cannot occur until AE decreases 
to ≤Grade 1 or baseline assessment. In case of delayed recovery to Grade 1 or baseline 
(except for alopecia) from treatment-related AEs that results in a delay of treatment for 
> 6 weeks, the participant will not receive additional protocol-related treatment and will be 
removed from study unless discussed and agreed upon by the Sponsor/Medical Monitor and

investigators that it is in the best interest of the participant to receive additional treatment with 
BMS-986242 and nivolumab (eg, if the participant has demonstrated a response to treatment).

During the DLT evaluation period, if a participant receives dose reduction and experiences a

Criteria to Resume Treatment
Participants experiencing AEs not meeting criteria for permanent discontinuation as outlined in
Section 8.1 and Section 8.2 may resume treatment with study treatment under the following 
criteria:

Participants may resume treatment with study treatment when the study treatment-related 
AE(s) resolves to Grade 1 or baseline value with the following EXCEPTIONS:

Participants may resume treatment in the presence of Grade 2 fatigue.

Participants who have not experienced a Grade 3 study treatment-related skin AE may 
resume treatment in the presence of Grade 2 skin toxicity.

Participants with Grade 2 uveitis or eye pain or blurred vision not meeting DLT criteria 
(Section 7.4.1) must resolve to baseline prior to resuming study treatment.

Study treatment-related pulmonary toxicity, diarrhea, or colitis must have resolved to baseline 
before treatment is resumed.

Participants with study treatment-related endocrinopathies adequately controlled with only 
physiologic hormone replacement may resume treatment.

If the criteria to resume treatment are met, the participant should restart treatment at the next 
scheduled time point per protocol.

The consideration to re-initiate study treatment under these exceptions will be made on a 
case-by-case basis after considering the overall benefit/risk profile and in consultation between 
the investigator and the study Sponsor. Any AE with clinical risk will be assessed on a 
case-by-case basis with the investigator and the BMS Medical Monitor to determine the risks 
and benefits of continuing on study treatment following resolution versus discontinuing study 
treatment permanently. 

If treatment with study treatment is delayed > 6 weeks, the participant must be permanently 
discontinued from study treatment, except as specified in Section 7.4.2.
7.4.5
Guidelines for Permanent Discontinuation Secondary to Adverse 
Events
Participants will be required to permanently discontinue both study treatments for the following 
AEs:

Clinical deterioration, as assessed by the investigator

Grade 3 infusion reaction that does not return to Grade 1 in less than 6 hours

Grade 3 pneumonitis, bronchospasm, neurologic toxicity, uveitis, or myocarditis


Abnormal liver function tests meeting criteria for a potential DILI.

Any dosing delay lasting > 6 weeks will be cause for permanent discontinuation. Extensions 
to the period of dose delays may be granted for individual participants on a case-by-case basis 
after specific consultation and agreement between the investigator and BMS Medical Monitor 
in settings where benefit/risk may justify continued study treatment (eg, participant deriving 
clinical benefit who requires prolonged steroid taper for management of non-DLT 
immune-related AEs or experiences delays for management of a non-treatment-related AE).

Accordingly, dosing delays to allow for prolonged steroid tapers to manage study 
treatment-related AEs are allowed. Additionally, dosing delays > 6 weeks that occur for 
non-treatment-related reasons may be allowed if approved by the BMS Medical Monitor.

The consideration to re-initiate study treatment under these exceptions will be made on a 
case-by-case basis after considering the overall benefit/risk profile and in consultation between 
the investigator and the Sponsor.

Prior to re-initiating treatment in a participant with a dosing delay lasting > 6 weeks, the BMS 
Medical Monitor must be consulted.

Tumor assessments should continue per protocol even if dosing is delayed.
All participants who discontinue the IP should comply with protocol-specified follow-up 
procedures as outlined in Section 8.2. The only exception to this requirement is when a participant 
withdraws consent for all study procedures, including post-treatment study follow-up, or loses the 
ability to consent freely (eg, is imprisoned or involuntarily incarcerated for the treatment of either 
a psychiatric or physical illness).
If study treatment is discontinued prior to the participant’s completion of the study, the reason for 
the discontinuation must be documented in the participant’s medical records and entered on the 
appropriate case report form (CRF) page.

DISCONTINUATION CRITERIA
8.1
Discontinuation from Study Treatment
Participants MUST discontinue IP (and non-IP at the discretion of the investigator) for any of the 
following reasons:

Participant’s request to stop study treatment. Participants who request to discontinue study 
treatment will remain in the study and must continue to be followed for protocol-specified 
follow-up procedures. The only exception to this is when a participant specifically withdraws 
consent for any further contact with him/her or persons previously authorized by participant to 
provide this information.

Any clinical AE, laboratory abnormality, or intercurrent illness, which, in the opinion of the 
investigator, indicates that continued participation in the study is not in the best interest of the 
participant

Termination of the study by BMS

Loss of ability to freely provide consent through imprisonment or involuntarily incarceration 
for treatment of either a psychiatric or physical (eg, infectious disease) illness

Inability to comply with protocol

Discretion of the investigator

Pregnancy

Completion of study-required procedures

Documented and confirmed PD as defined by RECIST v1.1 (see Appendix 6) unless 
participant meets criteria for treatment beyond progression (Section 5.1.2.3)

Clinical deterioration while receiving active study treatment that, in the opinion of the 
investigator, indicates that continued participation in the study is not in the best interest of the 
participant

Protocol-defined reasons for discontinuation (see Section 7.4.5)
Refer to the Schedule of Activities (Section 2) for data to be collected at the time of treatment 
discontinuation and follow-up and for any further evaluations that can be completed.
If study treatment is discontinued prior to the participant’s completion of the study, the reason for 
the discontinuation must be documented in the participant’s medical records and entered on the 
appropriate CRF page.

Discontinuation of the study treatment for abnormal liver tests should be considered by the 
investigator when a participant meets the conditions outlined in Section 9.2.7.
8.1.1
Post Study Treatment Study Follow-up
Poststudy follow-up is of critical importance and is essential to preserving participant safety and 
the integrity of the study. Participants who discontinue study treatment must continue to be 
followed for collection of outcome and/or survival follow-up data as required and in line with 
Section 5.1.3 until death or the conclusion of the study.
8.2
Discontinuation from the Study
Participants who request to discontinue study treatment will remain in the study and must continue 
to be followed for protocol-specified follow-up procedures. The only exception to this is when a 
participant specifically withdraws consent for any further contact with him/her or persons 
previously authorized by the participant to provide this information. 

Participants should notify the investigator of the decision to withdraw consent from future 
follow-up in writing, whenever possible.

The withdrawal of consent should be explained in detail in the medical records by the 
investigator as to whether the withdrawal is from further treatment with study treatment only 
or also from study procedures and/or post-treatment study follow-up and entered on the 
appropriate CRF page.

In the event that vital status (whether the participant is alive or dead) is being measured, 
publicly available information should be used to determine vital status only as appropriately 
directed in accordance with local law.

If the participant withdraws consent for disclosure of future information, the Sponsor may 
retain and continue to use any data collected before such a withdrawal of consent.
8.3
Lost to Follow-up

All reasonable efforts must be made to locate participants to determine and report their ongoing 
status. This includes follow-up with persons authorized by the participant.

Lost to follow-up is defined as the inability to reach the participant after a minimum of 
3 documented phone calls, faxes, or emails as well as lack of response by the participant to one 
registered mail letter. All attempts should be documented in the participant’s medical records.

If it is determined that the participant has died, the site will use permissible local methods to 
obtain the date and cause of death.

If the investigator’s use of a third-party representative to assist in the follow-up portion of the 
study has been included in the participant’s informed consent, then the investigator may use a 
Sponsor-retained third-party representative to assist site staff with obtaining the participant’s 
contact information or other public vital status data necessary to complete the follow-up 
portion of the study. 

The site staff and representative will consult publicly available sources, such as public health 
registries and databases, in order to obtain updated contact information.

If after all attempts, the participant remains lost to follow-up, then the last known alive date as 
determined by the investigator should be reported and documented in the participant’s medical 
records.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and timing are summarized in the Schedule of Activities (Section 2). 

Protocol waivers or exemptions are not allowed.

All immediate safety concerns must be discussed with the Sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue 
treatment.

Adherence to the study design requirements, including those specified in the Schedule of 
Activities, is essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria before treatment. The investigator will maintain a 
screening log to record details of all participants screened and to confirm eligibility or record 
reasons for screening failure, as applicable.

Procedures conducted as part of the participant’s routine clinical management (eg, blood count) 
and obtained before signing of informed consent may be utilized for screening or baseline 
purposes provided the procedure meets the protocol-defined criteria and has been performed 
within the timeframe defined in the Schedule of Activities.
9.1
Efficacy Assessments
Only data for the procedures and assessments specified in this protocol should be submitted to the 
Sponsor or Designee on a CRF. Additional procedures and assessments may be performed as part 
of standard of care. Data for these assessments, however, should remain in the participant’s 
medical record and should not be provided to the Sponsor or Designee unless specifically 
requested from BMS or designee.
Disease assessment with CT and/or MRI, as appropriate, will be performed at baseline, the end of 
Cycle 2, and every 8 weeks until disease progression, at the completion of follow-up, or until 
participants withdraw from the study (every 12 weeks for the first year after the EOT visit and then 
every 6 months thereafter up to 2 years from the last dose of study treatment). Disease assessments 
at other time points may be performed if the investigator is concerned about tumor progression. 
Assessment of tumor response will be reported based on investigator assessed tumor 
measurements as defined by RECIST v1.1 (see Appendix 6) for participants with solid tumors. 
Investigators will also report the number and size of new lesions that appear while on study. The 
time point tumor assessments will be reported on the CRF based on investigators’ assessment using 
RECIST. 
9.1.1
Imaging Assessment for the Study
Any incidental findings of potential clinical relevance that are not directly associated with the 
objectives of the protocol should be evaluated and handled by the study investigator as per standard 
medical/clinical judgment.

Body Imaging
CT with contrast is the preferred modality (MRI if CT is not feasible). Assessment should include 
the chest/abdomen/pelvis at a minimum; and other known/suspected sites of disease should be 
performed.
Disease assessment with CT and/or MRI as appropriate will be performed at baseline and as 
follows:

Parts 1 and 2: end of Cycle 2 and then every 8 weeks throughout the treatment period and 
every 12 weeks for the first year after the EOT visit, and then every 6 months thereafter, up to 
2 years from the last dose of study treatment during the follow-up period.
Disease assessments at other time points may be performed as clinically indicated.
Brain Imaging
Brain imaging is only required at screening for participants with known history or symptoms of 
brain metastases and who have not had brain imaging within 30 days of anticipated first study 
treatment administration. After screening, brain imaging is required only as clinically indicated.
Bone Scan
Bone scans may be performed as clinically indicated at baseline (eg, participants with history of 
symptoms of bone metastases), but bone scans will not be considered a modality for assessment 
for measurable disease. After baseline, bone scans are required only as clinically indicated.
Imaging Modalities
For all the solid tumor types, the following imaging assessments should be performed at a 
study-specified schedule: CT of the chest, CT or MRI of the abdomen, pelvis, and other known 
sites of disease, which is also summarized Table 9.1.1-1:

In all study parts, scans will be collected centrally and may be reviewed by a blinded independent 
central review at a later date or at any time during the study per Sponsor request.
9.1.2
Secondary Efficacy Assessment
The efficacy assessments will include the overall response rate (ORR) (eg, PR + CR rate), duration 
of response (DOR), and PFSR at time points (eg, 6, 9, 12, and 24 months) based on the assessment 
of tumor response using RECIST v1.1 criteria.
 
9.2
Adverse Events
The definitions of an AE or SAE can be found in Appendix 3.
AEs will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant’s legally authorized representative). 
The investigator and any designees are responsible for detecting, documenting, and reporting 
events that meet the definition of an AE or SAE and remain responsible for following up AEs that 
are serious, considered related to the study treatment or the study, or that caused the participant to 
discontinue before completing the study. 
Contacts for SAE reporting are specified in Appendix 3.

9.2.1
Time Period and Frequency for Collecting AE and SAE Information
The collection of nonserious AE information should begin at initiation of study treatment until 
100 days after discontinuation of study treatment, at the time points specified in the Schedule of 
Activities (Section 2). Nonserious AE information should also be collected from the start of a 
placebo lead-in period or other observational period intended to establish a baseline status for the 
participants.
Sections 5.6.1 and 5.6.2 in the IB represent the Reference Safety Information to determine 
expectedness of SAEs for expedited reporting. Following the participant’s written consent to 
participate in the study, all SAEs, whether related or not related to study treatment, must be 
collected, including those thought to be associated with protocol-specified procedures.
All SAEs must be collected from the date of participant’s written consent until 100 days after 
discontinuation of nivolumab or participation in the study (if the last scheduled visit occurs at a 
later time).
Medical occurrences that begin before the start of study treatment but after obtaining informed 
consent will be recorded on the appropriate section of the electronic CRF.

All SAEs will be recorded and reported to the Sponsor or designee within 24 hours, as indicated 
in Appendix 3. 

The investigator will submit any updated SAE data to the Sponsor within 24 hours of this being 
available.
Investigators are not obligated to actively seek AEs or SAEs in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a participant 
has been discharged from the study and he/she considers the event reasonably related to the study 
treatment or study participation, the investigator must promptly notify the Sponsor.
The method of evaluating and assessing causality of AEs and SAEs and the procedures for 
completing and reporting/transmitting SAE reports are provided in Appendix 3.
9.2.2
Method of Detecting AEs and SAEs
Adverse events can be spontaneously reported or elicited during open-ended questioning, 
examination, or evaluation of a participant. (In order to prevent reporting bias, participants should 
not be questioned regarding the specific occurrence of one or more AEs.)
9.2.3
Follow-up of AEs and SAEs

Nonserious AEs should be followed to resolution, until the condition stabilizes, until the event 
is otherwise explained, or until the participant is lost to follow-up or reported as SAEs if they 
become serious (see Appendix 3).

Follow-up is also required for nonserious AEs that cause interruption or discontinuation of 
study treatment and for those present at the end of study treatment as appropriate.

All identified nonserious AEs must be recorded and described on the nonserious AE page of 
the CRF (paper or electronic). Completion of supplemental CRFs may be requested for AEs 
and/or laboratory abnormalities that are reported/identified during the course of the study.

After the initial AE/SAE report, the investigator is required to proactively follow each participant 
at subsequent visits/contacts. All SAEs will be followed until resolution, until the condition 
stabilizes, until the event is otherwise explained, or until the participant is lost to follow-up (as 
defined in Section 8.3).
Further information on follow-up procedures is given in Appendix 3.
9.2.4
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the Sponsor of SAEs is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
product under clinical investigation are met.

An investigator who receives an investigator safety report describing SAEs or other specific 
safety information (eg, summary or listing of SAEs) from the Sponsor will file it along with 
the IB and will notify the institutional review board/institutional ethics committee, if 
appropriate, according to local requirements.
The Sponsor or designee will be reporting adverse events to regulatory authorities and ethics 
committees according to local applicable laws, including European Directive 2001/20/EC and 
Food and Drug Administration Code of Federal Regulations 21 CFR Parts 312 and 320. A 
Suspected, Unexpected Serious Adverse Reaction is a subset of SAEs and will be reported to the 
appropriate regulatory authorities and investigators following local and global guidelines and 
requirements.
9.2.5
Pregnancy
If, following initiation of the study treatment, it is subsequently discovered that a participant is 
pregnant or may have been pregnant at the time of study exposure, including during at least 
5 half-lives after product administration, the investigator must immediately notify the BMS 
Medical Monitor/designee of this event and complete and forward a Pregnancy Surveillance Form 
to the BMS Designee within 24 hours of awareness of the event and in accordance with SAE 
reporting procedures described in Appendix 3.
In most cases, the study treatment will be permanently discontinued in an appropriate manner 
(eg, dose tapering if necessary for participant safety). Please call the BMS Medical Monitor within 
24 hours of awareness of the pregnancy.
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
participant.
Follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome and, where applicable, and offspring information must be reported on the Pregnancy 
Surveillance Form.
Any pregnancy that occurs in a female partner of a male study participant should be reported to 
Sponsor or designee. In order for Sponsor or designee to collect any pregnancy surveillance

information from the female partner, the female partner must sign an ICF for disclosure of this 
information. Information on this pregnancy will be collected on the Pregnancy Surveillance Form.
9.2.6
Laboratory Test Result Abnormalities
The following laboratory test result abnormalities should be captured on the nonserious AE CRF 
page or electronic SAE Report Form, as appropriate. Paper forms are only intended as a back-up 
option when the electronic system is not functioning.

Any laboratory test result that is clinically significant or meets the definition of an SAE 

Any laboratory test result abnormality that required the participant to have study treatment 
discontinued or interrupted

Any laboratory test result abnormality that required the participant to receive specific 
corrective therapy
It is expected that, wherever possible, the clinical rather than laboratory term would be used by the 
reporting investigator (eg, anemia versus low hemoglobin value).
9.2.7
Potential Drug-induced Liver Injury
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. All occurrences of potential DILIs meeting 
the defined criteria must be reported as SAEs (see Section 9.2 and Appendix 3 for reporting 
details).
Potential DILI is defined as: 

AT (ALT or AST) elevation > 3×ULN
AND

Total bilirubin > 2ULN, without initial findings of cholestasis (elevated serum alkaline 
phosphatase),
AND

No other immediately apparent possible causes of AT elevation and hyperbilirubinemia, 
including, but not limited to, viral hepatitis, pre-existing chronic or acute liver disease, or the 
administration of other drug(s) known to be hepatotoxic.
9.2.8
Other Safety Considerations
Any significant worsening noted during interim or final PEs, ECG, X-ray filming, or any other 
potential safety assessment required or not required by protocol should also be recorded as a 
nonserious or serious AE, as appropriate, and reported accordingly.
9.3
Overdose
For this study, any dose of BMS-986242 greater than the assigned dose and considered both 
excessive and medically important by the investigator in consultation with the Medical Monitor 
will be considered an overdose. All occurrences of overdose must be reported as SAEs (see 
Section 9.2)

concentration versus time and urinary excretion data. Individual participant PK parameter values 
will be derived by noncompartmental methods by a validated PK analysis program. Actual times 
will be used for the analyses.
The PK parameters to be assessed for BMS-986242 and selected metabolites following single-dose 
administration in Cycle 00 and multiple-dose administration in Cycle 0 include but are not limited 
to:
Cmax
Maximum observed plasma concentration
Tmax
Time of maximum observed plasma concentration
AUC(0-T)
Area under the concentration-time curve from 0 to last observed 
collection time (clinical pharmacology substudy)
AUC(INF)

Plasma samples for BMS-986242 will be collected for all participants receiving combination 
treatment with BMS-986242 and nivolumab. Plasma concentration data will be tabulated using 
summary statistics. These data, together with data from the monotherapy, may also be pooled with 
other datasets for PPK analysis, which will be presented in a separate report.
Serum samples for nivolumab PK and immunogenicity assessments will be collected for all 
participants receiving combination treatment of BMS-986242 and nivolumab. End-of-infusion and 
trough concentrations will be tabulated using summary statistics. These data may also be pooled 
with other datasets for PPK analysis, which will be presented in a separate report.
9.5.3
Pharmacokinetics: Collection and Processing
Detailed sampling schedules to be followed for the assessment of PK and immunogenicity for all 
analytes in the study are provided in Table 9.5.3-1. All time points are relative to the start of 
BMS-986242 dosing. Predose samples should be taken within 30 minutes before the start of 
BMS-986242 administration. Nivolumab end-of-infusion samples should be taken just prior to the 
end of infusion (preferably within 2 minutes). Further details of sample collection, processing, and 
shipment will be provided in the laboratory procedures manual. On-treatment PK samples are 
intended to be drawn relative to actual dosing days; if a dose occurs on a different day within the 
cycle due to delays or minor schedule adjustments, PK samples should be adjusted accordingly.
Table 9.5.3-2 lists the PK sampling and ECG collection schedules to be followed for the clinical 
pharmacology substudy (Cycle 00). Serial ECGs (reviewed by a core laboratory) will be collected 
with matching PK samples. Twelve-lead continuous ECG (Holter) will be used in the QTc 
substudy. Each ECG time point will be collected in triplicates. ECGs should be performed after 
the participant has been resting supine for at least 10 minutes and should be completed prior to any 
PK/pharmacodynamic sample blood collections when assessments occur at the same time points. 
All serial ECGs will be transmitted to a central laboratory for measurement of intervals and 
classification of ECG abnormalities. At the end of the clinical pharmacology substudy, participants 
will follow PK collection schedule after BMS-986242 + nivolumab combination treatment 
provided in Table 9.5.3-1.

STATISTICAL CONSIDERATIONS
10.1
Sample Size Determination 
10.1.1
Dose Escalation
During the dose-escalation trial, the sample size at each dose in these arms depends on observed 
toxicity and posterior inference. 
Up to approximately 78 participants are planned to be enrolled for Part 1 (dose escalation) and 
clinical pharmacology substudy: approximately 30 participants for the dose-escalation phase, with 
up to 24 additional participants in Part 1 for additional characterization of the safety, PK, and 
pharmacodynamic profile of BMS-986242, and approximately 24 participants for the clinical 
pharmacology substudy (including food effect). Appendix 7 provides additional details for the 
operating characteristics of the BLRM for monotherapy and BLRM-copula for combination 
therapy based on doses from 25 mg; an addition of 12.5 mg is expected to provide similar operating 
characteristics..
For the food effect assessment, the sample size is not based on statistical power for comparison 
but on consideration of the precision of the estimates of geometric means of Cmax and AUC(0-T) 
of BMS-986242.
For a sample size of 6 participants, there is an 80% probability for the 90% confidence interval to 
be within 79.6% to 125.7% of the point estimate of the geometric mean for Cmax and within 
80.4% to 124.4% of the point estimate of the geometric mean for AUC(0-T). This calculation 
assumes that log(Cmax) and log(AUC[0-T]) of BMS-986242 are normally distributed with a 
standard deviation (SD) of 0.23 and 0.22, respectively, as estimated from a study of a related 
compound.
10.1.2
Dose-expansion Cohort
Dose-expansion cohorts of BMS-986242 administered in combination with nivolumab in 
6 disease-restricted populations will be included. These are melanoma, NSCLC, SCCHN, RCC, 
bladder, and gastric cancer, with separate cohorts based on prior PD-(L)1 exposure in 5 of the 
tumor types (except gastric cancer). Approximately 20 participants will be included for each dose-
expansion cohort, for a total of 220 participants for Part 2. The sample size of 20 participants per 
dose-expansion cohort is not based on statistical power for comparison but on consideration of the 
precision of the estimates for ORR proportion. A total of 20 participants are expected to provide a 
standard error of the estimate of 7% to 11% for ORR proportions between 10% and 50%.
10.2

and the participant informed consent will receive approval/favorable opinion by Institutional 
Review Board/Independent Ethics Committee (IRB/IEC) and regulatory authorities according to 
applicable local regulations prior to initiation of the study.
All potential serious breaches must be reported to the Sponsor or designee immediately. A serious
breach is a breach of the conditions and principles of GCP in connection with the study or the 
protocol, which is likely to affect, to a significant degree, the safety or physical or mental integrity 
of the subjects of the study or the scientific value of the study.
Personnel involved in conducting this study will be qualified by education, training, and 
experience to perform their respective tasks.
This study will not use the services of study personnel where sanctions have been invoked or where 
there has been scientific misconduct or fraud (eg, loss of medical licensure, debarment). 
INSTITUTIONAL REVIEW BOARD/INDEPENDENT ETHICS COMMITTEE
Before study initiation, the investigator must have written and dated approval/favorable opinion 
from the IRB/IEC for the protocol, consent form, participant recruitment materials (eg, 
advertisements), and any other written information to be provided to subjects. The investigator or 
BMS should also provide the IRB/IEC with a copy of the Investigator Brochure or product labeling 
information and any updates.

COMPLIANCE WITH THE PROTOCOL AND PROTOCOL REVISIONS
The investigator should not implement any deviation or change to the protocol without prior 
review and documented approval/favorable opinion of an amendment from the IRB/IEC (and if 
applicable, also by local health authority) except where necessary to eliminate an immediate 
hazard(s) to study subjects. 
If a deviation or change to a protocol is implemented to eliminate an immediate hazard(s) prior to 
obtaining relevant approval/favorable opinion(s) the deviation or change will be submitted, as soon 
as possible to:

IRB/IEC

Regulatory Authority(ies), if applicable by local regulations (per national requirements)
Documentation of approval/favorable opinion signed by the chairperson or designee of the 
IRB(s)/IEC(s) and, if applicable, also by local health authority must be sent to BMS.
If an amendment substantially alters the study design or increases the potential risk to the 
participant, (1) the consent form must be revised and submitted to the IRB(s)/IEC(s) for review 
and approval/favorable opinion, (2) the revised form must be used to obtain consent from subjects 
currently enrolled in the study if they are affected by the amendment, and (3) the new form must 
be used to obtain consent from new subjects prior to enrollment.
If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
FINANCIAL DISCLOSURE
Investigators and subinvestigators will provide the Sponsor with sufficient, accurate financial 
information in accordance with local regulations to allow the Sponsor to submit complete and 
accurate financial certification or disclosure statements to the appropriate health authorities. 
Investigators are responsible for providing information on financial interests during the course of 
the study and for 1 year after completion of the study.
INFORMED CONSENT PROCESS
Investigators must ensure that subjects are clearly and fully informed about the purpose, potential 
risks, and other critical issues regarding clinical studies in which they volunteer to participate. 
In situations where consent cannot be given to subjects, their legally acceptable representatives (as 
per country guidelines) are clearly and fully informed about the purpose, potential risks, and other 
critical issues regarding clinical studies in which the participant volunteers to participate. 
The sponsor or designee will provide the investigator with an appropriate (i.e., Global or Local) 
sample informed consent form, which will include all elements required by ICH, GCP, and 
applicable regulatory requirements. The sample informed consent form will adhere to the ethical 
principles that have their origin in the Declaration of Helsinki.

Investigators must:

Provide a copy of the consent form and written information about the study in the language 
in which the participant is most proficient prior to clinical study participation. The language 
must be non-technical and easily understood. 

Allow time necessary for participant or participant’s legally acceptable representative to 
inquire about the details of the study.

Obtain an informed consent signed and personally dated by the participant or the 
participant’s legally acceptable representative and by the person who conducted the 
informed consent discussion. 

Obtain the IRB/IEC’s written approval/favorable opinion of the written informed consent 
form and any other information to be provided to the subjects, prior to the beginning of the 
study, and after any revisions are completed for new information.
If informed consent is initially given by a participant’s legally acceptable representative or legal 
guardian, and the participant subsequently becomes capable of making and communicating his or 
her informed consent during the study, consent must additionally be obtained from the participant.
Revise the informed consent whenever important new information becomes available that is 
relevant to the participant's consent. The investigator, or a person designated by the investigator, 
should fully inform the participant or the participant’s legally acceptable representative or legal 
guardian, of all pertinent aspects of the study and of any new information relevant to the 
participant's willingness to continue participation in the study. This communication should be 
documented. 
The confidentiality of records that could identify subjects must be protected, respecting the privacy 
and confidentiality rules applicable to regulatory requirements, the subjects’ signed ICF, and, in 
the US, the subjects’ signed HIPAA Authorization.
The consent form must also include a statement that BMS and regulatory authorities have direct 
access to participant records. 
Subjects unable to give their written consent (eg, because of stroke or severe dementia) may only 
be enrolled in the study with the consent of a legally acceptable representative. The participant
must also be informed about the nature of the study to the extent compatible with his or her 
understanding, and should this participant become capable, he or she should personally sign and 
date the consent form as soon as possible. The explicit wish of a participant who is unable to give 
his or her written consent, but who is capable of forming an opinion and assessing information to 
refuse participation in, or to be withdrawn from, the clinical study at any time should be considered 
by the investigator.
The rights, safety, and well-being of the study subjects are the most important considerations and 
should prevail over interests of science and society.

SOURCE DOCUMENTS
The investigator is responsible for ensuring that the source data are accurate, legible, 
contemporaneous, original, and attributable, whether the data are hand-written on paper or entered 
electronically. If source data are created (first entered), modified, maintained, archived, retrieved, 
or transmitted electronically via computerized systems (and/or any other kind of electronic 
devices) as part of regulated clinical trial activities, such systems must be compliant with all 
applicable laws and regulations governing use of electronic records and/or electronic signatures. 
Such systems may include, but are not limited to, electronic medical/health records (EMRs/EHRs), 
adverse event tracking/reporting, protocol required assessments, and/or drug accountability 
records.
When paper records from such systems are used in place of electronic format to perform regulated 
activities, such paper records should be certified copies. A certified copy consists of a copy of 
original information that has been verified, as indicated by a dated signature, as an exact copy 
having all of the same attributes and information as the original. 
STUDY TREATMENT RECORDS
Records for study treatments (whether supplied by BMS, its vendors, or the site) must substantiate 
study treatment integrity and traceability from receipt, preparation, administration, and through 
destruction or return. Records must be made available for review at the request of BMS/designee

CASE REPORT FORMS
An investigator is required to prepare and maintain adequate and accurate case histories designed 
to record all observations and other data pertinent to the investigation on each individual treated 
or entered as a control in the investigation. Data that are derived from source documents and 
reported on the CRF must be consistent with the source documents or the discrepancies must be 
explained. Additional clinical information may be collected and analyzed in an effort to enhance 
understanding of product safety. CRFs may be requested for AEs and/or laboratory abnormalities 
that are reported or identified during the course of the study.
For sites using the Sponsor or designee electronic data capture tool, electronic CRFs will be 
prepared for all data collection fields except for fields specific to SAEs and pregnancy, which will 
be reported on the electronic SAE form and Pregnancy Surveillance form, respectively.  If an 
electronic SAE form is not available, a paper SAE form can be used. Spaces may be left blank 
only in those circumstances permitted by study-specific CRF completion guidelines provided by 
the Sponsor or designee.
The confidentiality of records that could identify subjects must be protected, respecting the privacy 
and confidentiality rules in accordance with the applicable regulatory requirement(s).
The investigator will maintain a signature sheet to document signatures and initials of all persons 
authorized to make entries and/or corrections on CRFs. 
The completed CRF, including SAE/pregnancy CRFs, must be promptly reviewed, signed, and 
dated by the investigator or qualified physician who is a subinvestigator and who is delegated this 
task on the Delegation of Authority Form. Subinvestigators in Japan may not be delegated the CRF 
approval task. For electronic CRFs, review and approval/signature is completed electronically 
through the BMS electronic data capture tool. The investigator must retain a copy of the CRFs 
including records of the changes and corrections.
Each individual electronically signing electronic CRFs must meet Sponsor or designee training 
requirements and must only access the BMS electronic data capture tool using the unique user 
account provided by the Sponsor or designee. User accounts are not to be shared or reassigned to 
other individuals
MONITORING
Sponsor or designee representatives will review data centrally to identify potential issues to 
determine a schedule of on-site visits for targeted review of study records. 
Representatives of BMS must be allowed to visit all study site locations periodically to assess the 
data quality and study integrity. On site, they will review study records and directly compare them 
with source documents, discuss the conduct of the study with the investigator, and verify that the 
facilities remain acceptable. Certain CRF pages and/or electronic files may serve as the source 
documents.

In addition, the study may be evaluated by Sponsor or designee internal auditors and government 
inspectors who must be allowed access to CRFs, source documents, other study files, and study 
facilities. BMS audit reports will be kept confidential.
The investigator must notify BMS promptly of any inspections scheduled by regulatory authorities 
and promptly forward copies of inspection reports to the Sponsor or designee.
RECORDS RETENTION
The investigator (or head of the study site in Japan) must retain all study records and source 
documents for the maximum period required by applicable regulations and guidelines, or 
institutional procedures, or for the period specified by BMS or designee, whichever is longer. The 
investigator (or head of the study site in Japan) must contact BMS prior to destroying any records 
associated with the study.
BMS or designee will notify the investigator (or head of the study site in Japan) when the study 
records are no longer needed.
If the investigator withdraws from the study (eg, relocation, retirement), the records shall be 
transferred to a mutually agreed upon designee (eg, another investigator, study site, IRB). Notice 
of such transfer will be given in writing to BMS or designee.

ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS: 
DEFINITIONS AND PROCEDURES FOR RECORDING, 
EVALUATING, FOLLOW UP AND REPORTING
ADVERSE EVENTS
Adverse Event Definition:
An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a 
preexisting medical condition in a clinical investigation participant administered study drug and 
that does not necessarily have a causal relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of study drug, whether or not 
considered related to the study drug.

SERIOUS ADVERSE EVENTS
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any 
dose:
Results in death
Is life-threatening (defined as an event in which the participant was at risk of death at the time 
of the event; it does not refer to an event which hypothetically might have caused death if it 
were more severe)
Requires inpatient hospitalization or causes prolongation of existing hospitalization. The 
following hospitalizations are not considered SAEs in BMS clinical studies: 
o
a visit to the emergency room or other hospital department < 24 hours that does 
not result in admission (unless considered an important medical or life-
threatening event)
o
elective surgery, planned prior to signing consent
o
admissions as per protocol for a planned medical/surgical procedure
o
routine health assessment requiring admission for baseline/trending of health 
status (e.g., routine colonoscopy)
o
medical/surgical admission other than to remedy ill health and planned prior to 
entry into the study. Appropriate documentation is required in these cases
o
admission encountered for another life circumstance that carries no bearing on 
health status and requires no medical/surgical intervention (eg, lack of housing, 
economic inadequacy, caregiver respite, family circumstances, administrative 
reason)
o
admission for administration of anticancer therapy in the absence of any other 
SAEs (applies to oncology protocols)
Results in persistent or significant disability/incapacity or substantial disruption of the ability to 
conduct normal life functions
Results in a congenital anomaly/birth defect
Is an important medical event (defined as a medical event[s] that may not be immediately life-
threatening or result in death or hospitalization but, based upon appropriate medical and 
scientific judgment, may jeopardize the participant or may require intervention [eg, medical, 
surgical] to prevent one of the other serious outcomes listed in the definition above). Examples 
of such events include, but are not limited to, intensive treatment in an emergency room or at 
home for allergic bronchospasm and blood dyscrasias or convulsions that do not result in 
hospitalization. Potential drug-induced liver injury (DILI) is also considered an important 
medical event. (See Section 9.2.7 for the definition of potential DILI.)

Suspected transmission of an infectious agent (eg, pathogenic or nonpathogenic) via the study 
treatment is an SAE. 
Although pregnancy, overdose, cancer, and potential DILI are not always serious by regulatory 
definition, these events must be handled as SAEs. (See Section 9.2.5 for reporting pregnancies.)
Any component of a study endpoint that is considered related to study therapy should be reported 
as an SAE (eg, death is an endpoint, if death occurred due to anaphylaxis, anaphylaxis must be 
reported).
EVALUATING AES AND SAES
Assessment of Causality
The causal relationship to study drug is determined by a physician and should be used to 
assess all AEs. The causal relationship can be one of the following:
Related: There is a reasonable causal relationship between study drug 
administration and the AE.
Not related: There is not a reasonable causal relationship between study drug 
administration and the AE. 
The term "reasonable causal relationship" means there is evidence to suggest a causal 
relationship. 
Follow-up of AEs and SAEs
If only limited information is initially available, follow-up reports are required. (Note: 
Follow-up SAE reports must include the same investigator term[s] initially reported.) 
If an ongoing SAE changes in its intensity or relationship to study drug or if new 
information becomes available, the SAE report must be updated and submitted within 24 
hours to BMS (or designee) using the same procedure used for transmitting the initial SAE 
report.
All SAEs must be followed until resolution, until the condition stabilizes, until the event is 
otherwise explained, or until the participant is lost to follow-up.

WOMEN OF CHILDBEARING POTENTIAL DEFINITIONS AND 
METHODS OF CONTRACEPTION
DEFINITIONS
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. Permanent sterilization methods include hysterectomy, bilateral 
salpingectomy, and bilateral oophorectomy.
Women in the following categories are not considered WOCBP:

Premenarchal

Premenopausal with 1 of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s review of the participant’s medical 
records, medical examination, or medical history interview.

Postmenopausal 

A postmenopausal state is defined as 12 months of amenorrhea in a woman over age 45 
years in the absence of other biological or physiological causes. In addition, females under 
the age of 55 years must have a serum follicle-stimulating hormone (FSH) level 
> 40 mIU/mL to confirm menopause.
*Females treated with hormone replacement therapy are likely to have artificially suppressed FSH 
levels and may require a washout period in order to obtain a physiologic FSH level. The duration 
of the washout period is a function of the type of hormone replacement therapy used. The durations
of the washout period below are suggested guidelines and the investigators should use their 
judgement in checking serum FSH levels. 

1 week minimum for vaginal hormonal products (rings, creams, gels)

4 week minimum for transdermal products

8 week minimum for oral products
Other parenteral products may require washout periods as long as 6 months. If the serum FSH 
level is > 40 mIU/ml at any time during the washout period, the woman can be considered 
postmenopausal.

One of the highly effective methods of contraception listed below is required during study duration 
and until the end of relevant systemic exposure, as approximately 5 half-lives after the end of study 
treatment, plus 30 days.
Local laws and regulations may require use of alternative and/or additional contraception methods.


Bilateral tubal occlusion

Vasectomized partner 
A vasectomized partner is a highly effective contraception method provided that the partner is 
the sole male sexual partner of the WOCBP and the absence of sperm has been confirmed. If 
not, an additional highly effective method of contraception should be used. 

Sexual abstinence 
Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study drug. The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and 
the preferred and usual lifestyle of the participant.

It is not necessary to use any other method of contraception when complete abstinence 
is elected. 

WOCBP participants who choose complete abstinence must continue to have pregnancy 
tests, as specified in Section 2.

Acceptable alternate methods of highly effective contraception must be discussed in the event 
that the WOCBP participants chooses to forego complete abstinence.
NOTES:
a Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent with 
local regulations regarding the use of contraceptive methods for participants participating in clinical studies.
b Hormonal contraception may be susceptible to interaction with the study drug, which may reduce the efficacy of 
the contraceptive method. Hormonal contraception is permissible only when there is sufficient evidence that the 
IMP and other study medications will not alter hormonal exposures such that contraception would be ineffective or 
result in increased exposures that could be potentially hazardous. In this case, alternative methods of contraception 
should be utilized. 
c Intrauterine devices and intrauterine hormone releasing systems are acceptable methods of contraception in the 
absence of definitive drug interaction studies when hormone exposures from intrauterine devices do not alter 
contraception effectiveness.
Less Than Highly Effective Contraceptive Methods That Are User Dependent 
Failure rate of > 1% per year when used consistently and correctly.

Male or female condom with or without spermicide.  Male and female condoms cannot be 
used simultaneously.



Cervical cap with spermicide

Vaginal Sponge with spermicide


ASSESSMENT OF OVERALL TUMOR BURDEN AND MEASURABLE 
DISEASE
Only subjects with measurable disease at baseline should be included in protocols where 
objective tumor response is the primary endpoint. In studies where the primary endpoint is tumor 
progression (either time to progression or proportion with progression at a fixed date), the 
protocol must specify if entry is restricted to those with measurable disease or whether subjects 
having non-measurable disease only are also eligible.
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Measurable 
disease is defined by the presence of at least 1 measurable tumor lesion. When computed 
tomography (CT) scans have slice thickness greater than 5 mm, the minimum size for a 
measurable lesion should be twice the slice thickness.
At baseline, tumor lesions/lymph nodes will be categorized as measurable or non-measurable as 
follows.
1.1
Measurable Lesions
Measurable lesions must be accurately measured in at least 1 dimension (longest diameter in the 
plane of the measurement to be recorded) with the following minimum size:

10 mm by CT/magnetic resonance imaging (MRI) scan (CT/MRI scan slice thickness no 
greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions that cannot be accurately measured 
with calipers should be recorded as non-measurable)

20 mm by chest x-ray

Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph 
node must be 15 mm in short axis when assessed by CT scan (CT scan slice thickness 
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis 
will be measured and followed.
1.2
Non-measurable Lesions

All other lesions, including small lesions (longest diameter < 10 mm or pathological lymph 
nodes with 10 to < 15 mm short axis), as well as truly non-measurable lesions. 

Lesions considered truly non-measurable include the following: leptomeningeal disease, 
ascites, pleural or pericardial effusion, inflammatory breast disease, lymphangitic 
involvement of skin or lung, or abdominal masses/abdominal organomegaly identified by 
physical exam that is not measurable by reproducible imaging techniques.

Special Considerations Regarding Lesion Measurability
1.3.1
Bone Lesions

Bone scan, positron emission tomography (PET) scan, or plain films are not considered 
adequate imaging techniques to measure bone lesions. However, these techniques can be 
used to confirm the presence or disappearance of bone lesions. 

Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue components, that 
can be evaluated by cross-sectional imaging techniques such as CT or MRI can be considered 
as measurable lesions if the soft tissue component meets the definition of measurability 
described above.

Blastic bone lesions are non-measurable.
1.3.2
Cystic Lesions

Lesions that meet the criteria for radiographically defined simple cysts should not be 
considered as malignant lesions (neither measurable nor non-measurable) because they are, 
by definition, simple cysts. 

“Cystic lesions” thought to represent cystic metastases can be considered as measurable 
lesions if they meet the definition of measurability described above. However, if non-cystic 
lesions are present in the same subject, these are preferred for selection as target lesions.
1.3.3
Lesions with Prior Local Treatment
Tumor lesions situated in a previously irradiated area, or in an area subjected to other 
loco-regional therapy, are usually not considered measurable unless there has been demonstrated 
progression in the lesion. 
1.4
Specifications by Methods of Measurements
1.4.1
Measurement of Lesions
All measurements should be recorded in metric notation (mm). All baseline evaluations should 
be performed as close as possible to the treatment start and never more than 30 days before the 
beginning of the treatment.
1.4.2
Method of Assessment
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. Imaging-based evaluation should 
always be done rather than clinical examination unless the lesion(s) being followed cannot be 
imaged but are assessable by clinical exam.
1.4.2.1
CT/MRI Scan 
CT/MRI is the best currently available and reproducible method to measure lesions selected for 
response assessment. Measurability of lesions on CT/MRI scan is based on the assumption that 
CT/MRI 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.

1.4.2.2
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 
on chest x-ray may be considered measurable if they are clearly defined and surrounded by 
aerated lung.
1.4.2.3
Clinical Lesions 
Clinical lesions will only be considered measurable when they are superficial and 10 mm in 
diameter as assessed using calipers. For the case of skin lesions, documentation by color 
photography, including a ruler to estimate the size of the lesion, is suggested. As previously 
noted, when lesions can be evaluated by both clinical exam and imaging, imaging evaluation 
should be undertaken because it is more objective and may also be reviewed at the end of the 
study.
1.4.2.4
Ultrasound 
Ultrasound is not useful in the 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 or MRI is advised. 
1.4.2.5
Endoscopy and Laparoscopy
The utilization of these techniques for objective tumor evaluation is not advised.
1.4.2.6
Tumor Markers 
Tumor markers alone cannot be used to assess objective tumor response.

BASELINE DOCUMENTATION OF “TARGET” AND “NON-TARGET”
LESIONS
2.1
Target Lesions
When more than 1 measurable 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, and should lend themselves to reproducible repeated
measurements.
A sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all target 
lesions will be calculated and reported as the baseline sum diameters. If lymph nodes are to be 
included in the sum, then as noted below, only the short axis is added into the sum. The baseline 
sum diameters will be used as reference to further characterize any objective tumor regression in 
the measurable dimension of the disease.

Lymph Nodes
Lymph nodes merit special mention because they are normal anatomical structures that may be 
visible by imaging even if not involved by tumor. Pathological nodes that are defined as 
measurable and may be identified as target lesions must meet the criterion of a short axis of 
15 mm by CT scan. Only the short axis of these nodes will contribute to the baseline sum. 
Nodes that have a short axis < 10 mm are considered non-pathological and should not be 
recorded or followed.
2.2
Non-target Lesions
All other lesions (or sites of disease), including pathological lymph nodes, should be identified as 
non-target lesions and should also be recorded at baseline. Measurements are not required, and 
these lesions should be followed as “present,” “absent,” or, in rare cases, “unequivocal 
progression.” In addition, it is possible to record multiple non-target lesions involving the same 
organ as a single item on the case record form (eg, “multiple enlarged pelvic lymph nodes” or 
“multiple liver metastases”).

TUMOR RESPONSE EVALUATION
3.1
Evaluation of Target Lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes 
(whether target or non-target) must have reduction in short axis to < 10 mm.
Partial Response (PR):  At least a 30% decrease in the sum of diameters of target lesions,
taking as reference the baseline sum diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, 
taking as reference the smallest sum on study (this includes the baseline sum if that is the 
smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an 
absolute increase of at least 5 mm. (Note: the appearance of 1 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 diameters while on study.

3.1.1.2
Target Lesions That Become “Too Small to Measure”
All lesions (nodal and non-nodal) recorded at baseline should have their actual measurements 
recorded at each subsequent evaluation, even when very small (eg, 2 mm). If the radiologist is 
able to provide an actual measurement, that should be recorded, even if it is below 5 mm.
However, when such a lesion becomes difficult to assign, an exact measure then is as follows:

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. (Note: In case of a lymph node believed to be present and 
faintly seen but too small to measure, a default value of 5 mm should be assigned in this 
circumstance as well.) This default value is derived from the 5-mm CT slice thickness 
(but should not be changed with varying CT slice thickness). 
3.1.1.3
Target Lesions That Split or Coalesce on Treatment

When non-nodal lesions “fragment,” the longest diameters of the fragmented portions should 
be added together to calculate the target lesion sum. 

As lesions coalesce, a plane between them may be maintained that would aid in obtaining 
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced 
such that they are no longer separable, the vector of the longest diameter in this instance 
should be the maximal longest diameter for the “coalesced lesion.”
3.2
Evaluation of Non-target Lesions
While some non-target lesions may actually be measurable, they need not be measured and 
instead should be assessed only qualitatively at the time points specified in the protocol. 
CR: Disappearance of all non-target lesions and normalization of tumor marker level. All lymph 
nodes must be non-pathological in size (< 10 mm short axis).
Non-CR/Non-PD: Persistence of 1 or more non-target lesion(s) and/or maintenance of tumor 
marker level above the normal limits.
PD: Unequivocal progression of existing non-target lesions. (Note: The appearance of 1 or more 
new lesions is also considered progression.)
3.2.1
Special Notes on the Assessment of Non-target Lesions
The concept of progression of non-target disease requires additional explanation as follows.
3.2.1.1
When the Subject Also Has Measurable Disease

To achieve “unequivocal progression” on the basis of the non-target disease, there must be an 
overall level of substantial worsening in non-target disease such that, even in the presence of 
SD or PR in the target disease, the overall tumor burden has increased sufficiently to merit 
discontinuation of therapy. 

A modest “increase” in the size of 1 or more non-target lesions is usually not sufficient to 
quality for unequivocal progression status.

3.2.1.2
When the Subject Has Only Non-measurable Disease

To achieve “unequivocal progression” on the basis of the non-target disease, there must be an 
overall level of substantial worsening such that the overall tumor burden has increased 
sufficiently to merit discontinuation of therapy. 

A modest “increase” in the size of 1 or more non-target lesions is usually not sufficient to 
qualify for unequivocal progression status. 

Because worsening in non-target disease cannot be easily quantified (by definition: if all 
lesions are non-measurable), a useful test that can be applied when assessing subjects for 
unequivocal progression is to consider if the increase in overall disease burden based on the 
change in non-measurable disease is comparable in magnitude to the increase that would be 
required to declare PD for measurable disease, ie, an increase in tumor burden representing 
an additional 73% increase in “volume” (which is equivalent to a 20% increase diameter in a 
measurable lesion). Examples include an increase in a pleural effusion from “trace” to 
“large,” an increase in lymphangitic disease from localized to widespread, or may be 
described in protocols as “sufficient to require a change in therapy.”

If “unequivocal progression” is seen, the subject should be considered to have had overall PD
at that point. 
3.2.1.3
Tumor Markers
Tumor markers alone cannot be used to assess objective tumor responses. If markers are initially 
above the upper normal limit, however, they must normalize in order for a subject to be 
considered as having attained a CR. 
3.3
New Lesions
The appearance of new malignant lesions denotes disease progression. The finding of a new 
lesion should be unequivocal, ie, not attributable to differences in scanning technique, change in 
imaging modality, or findings thought to represent something other than tumor (for example, 
some “new” bone lesions may be simply healing or flare of pre-existing lesions). This is 
particularly important when the subject’s baseline lesions show PR or CR. For example, necrosis 
of a liver lesion may be reported on a CT scan report as a new cystic lesion, which it is not.
A lesion identified on a follow-up study in an anatomical location that was not scanned at 
baseline is considered a new lesion and will indicate disease progression. An example of this is 
the subject who has visceral disease at baseline and, while on study, has a CT or MRI brain scan 
ordered that reveals metastases. The subject’s brain metastases are considered to be evidence of 
PD even if he/she did not have brain imaging at baseline.
For example, if a new lesion is equivocal because of its small size, continued therapy and 
follow-up evaluation will clarify if it represents truly new disease. If repeat scans confirm there 
is definitely a new lesion, then progression should be declared using the date of the initial scan.

4.1.1
Missing Assessments and Not Evaluable Designation
When no imaging/measurement is done at all at a particular time point, the subject is not 
evaluable (NE) at that time point. If only a subset of lesion measurements is made at an 
assessment, the case is also considered NE at that time point, unless a convincing argument can 
be made that the contribution of the individual missing lesion(s) would not have changed the 
assigned time point response.
4.1.2
Confirmation Scans
Verification of Response: Confirmation of PR and CR is required at least 4 weeks later to 
ensure that the responses identified are not the result of measurement error.
4.2
Best Overall Response: All Time Points
The best overall response is determined once all the data for the subject are known. It is the best 
response recorded from the start of the study treatment until objectively documented progression 
per RECIST Criteria or subsequent cancer therapy, whichever happens first, taking into account 
any requirement for confirmation. The subject’s best overall response assignment will depend on

the findings of both target and non-target disease and will also take into consideration the 
appearance of new lesions. 
Best response is defined as the best response across all time points with subsequent confirmation. 
CR or PR may be claimed only if the criteria for each are met at a subsequent time point as 
specified in the protocol (generally 4 weeks later). 
In this circumstance, the best overall response can be interpreted as specified in Table 4.2-1. 
When SD is believed to be the best response, it must meet the protocol-specified minimum time 
from baseline. Measurements must have met the SD criteria at least once after study entry at a 
minimum interval (in general, not less than 6 weeks).

a If a CR is truly met at first time point, then any disease seen at a subsequent time point, even disease meeting PR 
criteria relative to baseline, makes the disease PD at that point (because disease must have reappeared after CR). 
Best response would depend on whether the minimum duration for SD was met. However, sometimes CR may be 
claimed when subsequent scans suggest that small lesions were likely still present and in fact the subject had PR, 
not CR, at the first time point. Under these circumstances, the original CR should be changed to PR, and the best 
response is PR.

STATISTICAL METHODOLOGY
STATISTICAL DETAILS FOR BAYESIAN LOGISTIC REGRESSION METHOD (BLRM 
AND BLRM-COPULA) MODEL AND PRIORS FOR DOSE ESCALATION
1
MODEL SETUP FOR BMS-986242 MONOTHERAPY (LEAD IN)
1.1
Monotherapy Methodology Description 
An adaptive 2-parameter Bayesian Logistic Regression Method (BLRM) model guided by the 
escalation with overdose control (EWOC) principle1,2,3 will be used to guide the dose escalation 
of BMS-986242 in the monotherapy lead-in phase and to provide dose recommendation during 
dose escalation. 
The BLRM will be fitted on the dose-limiting toxicity (DLT) data during the first 2 weeks of 
treatment accumulated throughout the dose escalation to model the dose-toxicity relationship of 
BMS-986242 in the monotherapy lead-in phase. 
The dose-toxicity relationship for BMS-986242 monotherapy is assumed to follow a logistic 
model:
݈݋݃݅ݐ(݌௜) = ݈݋݃(ߙଵ) + ߚଵ݈݋݃(݀ଵ௜݀ଵ
∗
൘),
where ݌௜is the probability of toxicity at dose level ݀ଵ௜. Note that the ߙଵand ߚଵparameters are 
assumed positive and ݀ଵ
∗is the reference dose for BMS-986242 (please refer to the meaning of 
ߙଵand ߚଵin Section 1.2.1 for detailed implementation).
1.2
Prior Specification for BMS-986242 Monotherapy
The Bayesian approach requires the specification of prior distributions for model parameters,
which include parameters (ߙଵ, ߚଵ) for BMS-986242. The prior distributions for BMS-986242
single-agent activity were derived using a weakly informative prior, as well as discussion with the 
Bristol-Myers Squibb (BMS) clinical team.
Derivation of prior distribution of these parameters is provided in the following subsections.
1.2.1
Prior Derivation for BMS-986242 Parameters (࢒࢕ࢍ(ࢻ૚), ࢒࢕ࢍ(ࢼ૚))
A weakly informative prior will be used for parameters (ߙଵ, ߚଵ) for BMS-986242 to reflect the 
potential of the different toxicities of BMS-986242 and allow for considerable prior uncertainty.
Further details are provided below.
Weakly Informative Prior

The median DLT rate at the reference dose (BMS-986242 at 600 mg QD) was assumed to be 
30%, that is, mean (log(ߙଵ)) = logit (0.3) = log(0.3/(1-0.3)) = -0.847.

A doubling in dose was assumed to double the odds of DLT, that is, mean(log(ߚଵ)) = 0.
The standard deviation of log(ߙଵ) was set to 1.53 using the following steps:

If the toxicity probability range was set to be [1%, 99%], then the toxicity interval would be 
logit (0.99)-logit (0.01) = 9.19.


To cover 99.7% of the variance, the toxicity interval will cover 6*standard deviation (SD)
(log(ߙଵ)), which gives us SD (log(ߙଵ)) = 9.19/6 = 1.53.
Correspondingly, the standard deviation of log(ߚଵ) was set to 1, which allows for considerably
larger prior uncertainty for the dose toxicity.
1) The correlation between log(ߙଵ) and log(ߚଵ) was set to 0.
2) log(ߙଵ) and log(ߚଵ) follow a bivariate normal distribution.

MODEL SETUP FOR BMS-986242 AND NIVOLUMAB COMBINATION
2.1
Methodology Description for Combination Therapy
Toxicity profiles of both BMS-986242 monotherapy and nivolumab monotherapy will be 
incorporated to develop the combination model framework. A copula-type model will be used to 
cover all general combination cases, including additive and synergistic effects. The combination 
of the 2 treatments will be explored using a Bayesian hierarchical model by utilizing the toxicity 
profiles of the single agents as prior marginal profiles for the combination. The following copula-
type model4 will be used to describe the probability ݌௜௝of toxicity when dose level ݅of agent A 
and dose level ݆of agent B are administered in combination:

ߛଵcharacterizes the drug-drug interactive effect.
The joint toxicity framework models the toxicity rates of both agents as well as their interaction 
effects in a 7-parameter hierarchical model, where each monotherapy dose-toxicity relationship 
will be characterized by a 2-parameter BLRM model (see Section 1.1). There are 3 additional 
parameters for the copula-type model, 1 for each agent (݉and ݊) as well as 1 for the interaction 
term (ߛଵ). A dose-toxicity surface will be characterized for different dose combinations of these 2
agents.
As there are currently no historical data or prior knowledge to indicate how much information is 
to be borrowed for each of the single agents, parameters ݉and ݊are both set to be 1, meaning 
borrowing 100% of the information from the 2 agents. The above formula is then simplified into 
a 5-parameter model as follows:

copula-type model [ߛଵ, which will be discussed in detail in the following section]) will be fitted
into the in-house developed model. It implements the above-described theoretical setup.

Prior Specification for Combination Therapy
2.2.1
Marginal Prior for BMS-986242
Posterior information on log(1) and log(1) from the monotherapy Lead in will be used as 
marginal BMS-986242 prior for combination with nivolumab. This prior information is not 
prespecified and will be continuously updated when additional DLT information from the 
monotherapy is available. In the simulation (see Section 3, the prior of BMS-986242 as described 
in Section 1.2.1 (Table 1) is used for illustration purposes because no real-time DLT data are 
available at this time.
2.2.2
Marginal Prior Derivation for Nivolumab Parameters (log(2), log(2))
Similar to BMS-986242 monotherapy in the monotherapy phase, the logistic model for nivolumab 
is as follows:
݈݋݃݅ݐ൫ݍ௝൯= ݈݋݃(ߙଶ) + ߚଶ݈݋݃(݀ଶ௝
݀ଶ
∗
൘
), 
where ݍ௝is the probability of toxicity at dose level ݀ଶ௝. Note that the ߙଶܽ݊݀ߚଶparameters are 
assumed positive, and ݀ଶ
∗is the reference dose for nivolumab.
The toxicity profile of nivolumab has been studied in several studies. A bivariate normal prior for 
the nivolumab model parameters (log(2), log(2)) was obtained by extracting a posterior of 
nivolumab using DLT and safety data from the Study CA209003, which is used later as the meta-
analytical-predictive (MAP) prior for nivolumab. 
The MAP prior for the model parameters (log(2), log(2)) was obtained in the following steps.
First, a prior distribution for nivolumab was developed:

The median DLT rate at the reference dose (3 mg/kg every 2 weeks) was assumed to be 10%, 
that is, mean (log(2)) = logit(1/10) = log(1/9) = -2.197.

A doubling in dose was assumed to double odds of DLT, that is, mean(log(2)) = 0.

The standard deviation of log(2) was set to 2, and the standard deviation of log(2) to 1, which 
allows for considerable prior uncertainty for the dose-toxicity profile.

The correlation between log(2) and log(2) is assumed to be 0 (assuming independence of 
log(2) and log(2)).

In addition, heterogeneity between the historical study and current study was incorporated 
using a meta-analytic predictive approach by defining between-trial standard deviations 1 and 
2 for log(2) and log(2), respectively. The between-trial variability is assumed to be

moderate. Therefore, 1 and 2 were set to follow a log-normal distribution, with mean 
log(0.25) and log(0.125), respectively, with a common standard deviation log(2)/1.96.
With this prior, the clinical trial data below (Table 2) were used to generate the posterior for 
nivolumab, which is then used as the MAP prior for this study (Table 3).

Note: Nivolumab prior information was based on a milligram-per-kilogram dosing instead of flat dosing. If real PK 
data from this study show difference from the milligram-per-kilogram assumption, the nivolumab prior will be 
revisited and modified accordingly.
2.2.3
Prior for Interaction Parameters for Joint Toxicity of BMS-986242 and 
Nivolumab Combination
A gamma prior distribution for the interaction parameter γଵis derived to reflect the current 
uncertainty about the toxicity profile of the combination of BMS-986242 and nivolumab. Although 
no PK drug-drug interaction is expected, the possibility of a significant positive interaction 
between BMS-986242 and nivolumab cannot be totally excluded. The interaction parameter γଵ
was chosen accordingly but with a degree of uncertainty to allow for the possibility that the 
interaction may be positive or negative. Therefore, the following assumptions are made for the 
interaction parameter:

γଵfollows a gamma distribution and with a mean centered at 1.1, which means the combination 
of 2 agents is likely to have only a small synergistic effect.

The 97.5 percentile of γ1 is log(3), that is, a 3-fold increase in odds of DLT due to the 
interaction over independence at the starting dose of the combination.
This model assigns the highest probability to there being small synergistic interaction and also 
allows for the potential of larger synergism of the toxic profiles. It also does not completely ignore 
the possibility of antagonism because there is a 40% prior probability that γଵis less than 1.

DECISION RULE FOR DOSE ESCALATION AND SIMULATION
Dose escalation recommendations for BMS-986242 monotherapy and in combination with 
nivolumab will be based on the inference from the Bayesian posterior and the probability that the 
true DLT rate for each dose lies in 1 of the following categories:

[0%, 16%) under-dosing

[16%, 33%) targeted toxicity

[33%, 100%] excessive toxicity
These boundaries are similar to the toxicity boundaries used by a rule-based design (ie, 3 + 3 
design) in that a minimum is set at 16% (about 1 in 6) DLT rate and a maximum at 33% (about 2
in 6) DLT rate. Following the principle of EWOC, dose recommendations for the next cohort will 
be based on the Bayesian model after DLT information becomes available during the DLT period, 
accounting for all of the available data from the administered doses, and the candidate doses are 
the ones fulfilling the overdose criterion that there is less than 25% (for monotherapy) and 35% 
(for combination therapy) chances of excessive toxicity. Only the candidate doses will be 
considered for the next cohort. While the Bayesian model will use DLT information from the DLT 
period only, clinical assessment will take into consideration of the totality of available data 
including PK/Pharmacodynamics from all treated participants.
The MTD is the highest administered dose not expected to cause DLT in more than 33% of the 
treated participants during the DLT period. The final recommended MTD/RP2D will be based on 
the recommendation from the BLRM/BLRM-copula, and on an overall assessment of all available 
safety, PK/Pharmacodynamic, and efficacy data.
3.1
Simulation Parameters 
One thousand trial simulations were used for each scenario. All simulations were run using EAST 
6.3.1® software for BLRM model for BMS-986242 monotherapy and in-house developed code via 
R and Openbugs for BLRM-copula method for BMS-986242 in combination with nivolumab. The 
number of participants to be treated in each cohort in a specific dose level and the stopping rules 
used to declare MTD are defined as:

Fixed cohort size: 3

Probability of overdosing: < 25% for BLRM and 35% for BLRM-Copula

Probability of achieving the target toxicity: > 50%

Maximum number of participants treated: 30

Minimum number of participants treated at a given dose level in order to declare MTD: 6

Maximum number of participants at a dose:12
The provisional dose levels for BMS-986242 monotherapy are 25 mg through 600 mg. For the 
combination therapy, nivolumab is fixed at 480 mg flat dose for Q4W.

The average sample size was no more than 20 participants. The results for the scenarios of narrow 
safety window and all high show how the EWOC principle limits the risk of exposing participants 
from a toxic dose level. Overall, the scenarios illustrated above demonstrate that the model 
performs well in the hypothetical scenarios investigated by correctly identifying the MTD at least 
62% of the time while limiting participants from receiving excessive/unacceptable toxic dose 
levels.

INTERIM MONITORING CASE STUDY TO ILLUSTRATE PROVISION OF 
DOSE RECOMMENDATIONS DURING DOSE ESCALATION
In order to provide a comprehensive view of the dynamics of the models, different hypothetical 
scenarios exploring different possibilities are examined. For the simplicity of illustration purposes, 
a static cohort size of 3 subjects is applied for dose level 25 mg. This cohort size could vary during 
the actual clinical trial, and the BLRM (-Copula) models are designed to fit various different cohort 
sizes, adaptively. In general, there are many possible scenarios for a specific dose level, especially 
with a monotherapy lead-in followed by combination treatment. For example, there could be 0, 1,
2, or 3 DLTs observed in the monotherapy lead-in period, and similarly 0, 1, 2, or 3 DLTs observed 
in the combination period.

During interim monitoring, posterior probabilities will be updated when there is new DLT 
information available. The following two visualization plots will be produced to reflect the real 
time dose-DLT relationship, to quantify benefit (in the form of target dosing) and risk (in the form 
of overdosing and underdosing) during the model’s recommendation process, and to facilitate 
clinical team’s interpretation of the model recommendations for the final decision making:

Dose-DLT profile for the doses ranging between 0 mg and 600 mg (Figure 1).

Stacking histograms displaying predictive probabilities on DLT rates classified into 3 different 
categories (Underdosing, Target Dosing and Overdosing) (Figure 2).

Interpretation and usage of Figure 1:
Figure 1 is a snapshot of an updated dose-DLT profile with DLT information available at dose 
level 25 mg after the combination period (assuming there was no DLT in either monotherapy lead-
in or combination period). The dose-DLT profile is captured with a continuous dose spectrum 
ranging from 0 mg through 600 mg, which is a slice of the dose-DLT surface of the combination 
of two drugs with nivolumab fixed at 480 mg. For each dose within the range, there is a 
corresponding distribution of the predicted DLT rates calculated from the posterior samples of the

model parameters. This figure will be updated each time new DLT information becomes available
from different dose levels.
In Figure 1, there are 3 different quantiles (2.5%, 50%, and 97.5%) plotted to characterize the 
current trend of the toxicity profile (as shown by the 50% quantile), as well as the variation of the 
dose-DLT profile (as shown by the 2.5% quantile and the 97.5% quantile), according to the 
accumulation of DLT data from all previous and current dose levels. The toxicity boundaries (0.16 
and 0.33) are illustrated in two horizontal lines to benchmark the way in which the dose-DLT 
profile is trending. 
Intermediate dose levels can be identified using different boundary cutoffs. For example, using the 
50% quantile curve (green highlight), which represents the nearly average DLT distribution for 
each dose level, 350 mg could be a potential intermediate dose level corresponding to the lower 
pre-specified DLT rate boundary of 0.16, and 600 mg could be a fitted MTD dose level associated 
with the upper boundary of 0.33.
Moreover, if all of the current pre-specified doses are considered intolerable (overdosing 
probabilities > 0.35 for combination therapy, for example, a case not shown on the current Figure 
1), the model will recommend to stop the current dose level, and the clinical team can leverage the 
current updated dose-DLT curve to pinpoint a new dose, which is lower than pre-specified lowest 
dose (25 mg) by using the DLT rate boundaries.

Interpretation and usage of Figure 2:
Figure 2 is a snapshot of stacking histogram with DLT information available at dose level 25 mg
after combination period (assuming there was no DLT in either monotherapy lead-in or
combination period). This figure will be updated each time new DLT information becomes 
available in different dose levels.
When recommending the next dose level, the model will first exclude doses that are intolerable 
(with overdosing probabilities ≥35% or ≥25% for combination and monotherapy respectively). 
Among those qualified candidate doses that are considered “tolerable”, the model will select the 
dose that maximizes the probability of being within the target toxicity range (DLT rate of 16% up 
to 33%). 
As illustrated in Figure 2, when there is 0 DLT observed out of 3 subjects for the dose level 25 mg
in both monotherapy lead-in and combination, the distribution of predicted DLT rates will be 
characterized into possibilities falling into 3 different categories. Some dose levels for 
BMS-986242 might be excluded according to the higher-than-cutoff overdosing probabilities (eg,
600mg, > 35%). Among the remainder of tolerable dose levels, the BLRM (-Copula) model 
recommends the dose that maximizes the probability of being within the target dosing interval.

Therefore, the model’s recommendation would be to escalate to 400 mg, which is associated with 
the highest target dosing probability of 27% compared with that of other dose levels.
Similarly (although not shown on Figure 2), according to the rules specified above, the model 
could possibly recommend to de-escalate to a lower dose level than current treated dose level, 
extend the current dose level, or even to stop and identify a new dose level lower than 25 mg, the 
lowest pre-specified dose level. Please refer to description of Figure 1 for details on how to specify 
the new dose levels.

Example of the BLRM Using BMS-986242 Monotherapy Dose Escalation 
According to safety consideration and clinical judgement, dose level 25 mg is recommended as 
the starting dose for BMS-986242 monotherapy. With the current BMS-986242 prior specified in

a Sensitive CYP substrates refers to drugs whose plasma AUC values have been shown to increase 5-fold or higher 
when co-administered with a known CYP inhibitor.
b CYP substrates with narrow therapeutic range refers to drugs whose exposure-response relationship indicates that 
small increases in their exposure levels by the concomitant use of CYP inhibitors may lead to serious safety 
concerns (eg, Torsades de Pointes).
c Withdrawn from the United States market because of safety reasons.
Abbreviations: AUC = area under the concentration-time curve; CYP = cytochrome P450.

APPENDIX 9
MANAGEMENT ALGORITHMS FOR IMMUNO-ONCOLOGY 
AGENTS
These general guidelines constitute guidance to the Investigator and may be supplemented by 
discussions with the Medical Monitor representing the Sponsor. The guidance applies to all 
immuno-oncology (I-O) agents and regimens.
A general principle is that differential diagnoses should be diligently evaluated according to 
standard medical practice. Non-inflammatory etiologies should be considered and appropriately 
treated.
Corticosteroids are a primary therapy for I-O drug-related adverse events. The oral equivalent of 
the recommended intravenous doses may be considered for ambulatory patients with low-grade 
toxicity. The lower bioavailability of oral corticosteroids should be taken into account when 
switching to the equivalent dose of oral corticosteroids.
Consultation with a medical or surgical specialist, especially prior to an invasive diagnostic or 
therapeutic procedure, is recommended. 
The frequency and severity of the related adverse events covered by these algorithms will depend 
on the I-O agent or regimen being used.
