1.  SYNOPSIS 
 
Trial Title 
A Phase II Two-Arm Open-Label Study of Nivolumab plus Relatlimab or Ipilimumab in 
Metastatic Melanoma Stratified by MHC-II Expression. 
Trial Sites 
Vanderbilt University Medical Center and approximately 2 additional academic 
medical centers in the United States. 
Overall  
Design 
This is an open-label, non-randomized two arm Phase 2 study of intravenous 
nivolumab plus intravenous ipilimumab or intravenous relatlimab in patients with 
metastatic melanoma stratified by MHC-II expression. 
Hypothesis 
Patients with MHC-II expressing melanomas will have high rates of change in 
activated GZMB+ CD8+ T-cell density intratumorally with nivolumab and relatlimab 
therapy; MHC-II expression is an effective stratifying marker in melanoma that can be 
used in future studies to select optimal treatment.  
Study  
Design 
Patients will be stratified into 2 arms:   
Arm A: MHC-II positive patients, and Arm B: MHC-II negative patients. 
 
Arm A:  Treatment will consist of cycles lasting 28 days (4 weeks) per cycle 
(nivolumab + relatlimab): 
 
• 
On Day 1 of each 28-day cycle, all patients are scheduled to receive 
nivolumab and relatlimab intravenously.   
 
Arm B:  Treatment will consist of four initial cycles lasting 21 days (3 weeks) per cycle 
(nivolumab + ipilimumab); followed by cycles lasting 28 days (4 weeks) for  nivolumab 
monotherapy:  
 
• 
On Day 1 of cycles 1-4, all patients are scheduled to receive ipilimumab and 
nivolumab intravenously. 
 
Starting with cycle 5, patients will receive nivolumab intravenously every 4 weeks. 
Duration of  
Treatment 
It is intended that patients will be treated until RECIST 1.1 confirmed disease 
progression, until intolerable toxicity, or up to a maximum of 2 years after initiation of 
study treatment.   
Objectives and  
Efficacy 
Measures 
Primary Objective:  
• 
To evaluate the efficacy, measured by change in activated GZMB+ CD8+  
T-cell density intratumorally, of two immunotherapy regimens in patients with 
advanced melanoma:   
 nivolumab plus relatlimab in patients with MHC-II (+) melanoma, and  
 nivolumab plus ipilimumab in patients with MHC-II (-) melanoma. 
 
Secondary Objectives:  
• 
To evaluate the response rate, median progression free survival, overall 
survival, and safety and tolerability of nivolumab plus relatlimab in patients 
with MHC-II (+) melanoma, and of nivolumab plus ipilimumab in patients with 
MHC-II (-) melanoma.

2.  SCHEMA 
 
The study design schematic is presented in Figure 1:  
 
 
 
 
 
 
 
 
 
 
 
 
 
Approximately 18 participants will be enrolled in each arm of the study.  Accrual in a given arm will 
stop when 18 participants in the arm have enrolled.  All participants may receive study treatment: 
until confirmed progression of disease, unacceptable toxicity, participant withdrawal of consent, or 
study closure. 
 
The study will consist of three phases: screening, treatment, and follow-up as detailed below.   
 
2.1.  Screening Phase 
 
• 
Begins by signing of the informed consent form (ICF) and establishing the participant’s eligibility. 
 
• 
Participant is assessed for complete study eligibility as described in Section 5. 
 
• 
A pregnancy test for WOCBP documented within 72 hours prior to the start of the first dose of 
study medication. 
 
• 
Tumor tissue must be received at Vanderbilt University Medical Center (VUMC) for MHC-II 
testing in order for the participant to be enrolled in the correct arm of the study. MHC-II positivity 
is defined as ≥5% of tumor cells expressing MHC-II.  
 
2.2.  Treatment Phase 
 
• 
Begins upon subject’s initiation of protocol-indicated treatment. 
 
• 
Arm A:  Nivolumab 480 mg IV and Relatlimab 160mg IV are administered on day 1 of every 4 
week cycle until disease progression, discontinuation due to unacceptable toxicity, withdrawal of 
consent or study closure, or 104 weeks of treatment. 
 
• 
Arm B:  Nivolumab 1mg/kg IV and Ipilimumab 3mg/kg IV are administered on day 1 of every 3 
week cycle for 4 doses.  Then, nivolumab 480mg IV is administered on day 1 of every 4 week

cycle until disease progression, discontinuation due to unacceptable toxicity, withdrawal of 
consent or study closure, or 104 weeks of treatment. 
 
• 
Treatment beyond initial investigator-assessed RECIST 1.1-defined progression is permitted if 
the subject has investigator-assessed clinical benefit and is tolerating treatment. 
 
• 
Study assessments are to be collected as outlined in Section 7. 
 
• 
This phase ends when the participant is discontinued from study therapy or at a maximum of 2 
years of treatment. 
 
2.3.  Post-treatment Follow-up Phase 
 
• 
Begins after 2 years of treatment or when the decision is made to discontinue a participant from 
study therapy. 
 
• 
Subjects who discontinue treatment for reasons other than disease progression will continue to 
have tumor assessments (if clinically feasible) according to the schedule in Section 7 until 
progression or the start of any subsequent therapy, whichever occurs first. 
 
• 
Subjects will be followed for drug-related toxicities until these toxicities resolve, return to baseline 
or are deemed irreversible.  All treatment-related serious adverse events will be documented for a 
minimum of 100 days after the last dose of study.  
 
• 
After completion of the follow-up visit, subjects will be followed every 3 months (± 14 days) after 
patient’s last dose of study treatment – until death, end of the study, until lost to follow-up or 
patient withdraws consent, or for a maximum of 2 years after a patient’s final study treatment– 
whichever comes first.  Survival contact can be made via clinic visit, chart review, obituary or 
similar observation (e.g. Social Security death index), or by telephone.  The sponsor-investigator 
and/or BMS may request that survival data be collected on all treated subjects outside of the 
protocol defined window.  At that time of this request, each subject will be contacted to determine 
their survival status unless the subject had withdrawn consent for all contact.  
 
• 
Study assessments are to be collected as outlined in Section 7. 
 
3.  BACKGROUND AND RATIONALE 
 
3.1.  Introduction 
Advanced melanoma is historically associated with a dismal prognosis and limited therapeutic 
options.  Recently, advances in targeted and immune therapies have resulted in durable 
responses for nearly half of treated patients.  In particular, immune checkpoint inhibitors have 
driven long-term responses for a substantial fraction of treated patients.  Despite this, both intrinsic 
and acquired resistance remains a major limitation and at least half of patients still die of 
metastatic disease. 
 
Immune checkpoint inhibitors are agents that remove negative regulators of T cell responses. 
Immune checkpoints are terms for molecules such as programmed death-1 (PD-1), programmed 
death-ligands 1 (PD-L1) and 2 (PD-L2) that downregulate the host anti-tumor immune response, 
and are expressed in many cancer types.  Thus, these molecules play a key role in evading anti-
tumor immunity. 
 
Nivolumab (also referred to as BMS-936558 or MDX1106) is a human monoclonal antibody 
(HuMAb; immunoglobulin G4 [IgG4]-S228P) that targets the PD-1 cluster of differentiation 279 
(CD279) cell surface membrane receptor.  PD-1 is a negative regulatory molecule expressed by

activated T and B lymphocytes.  Binding of PD-1 to its ligands, PD-L1 and PD-L2, results in the 
down-regulation of lymphocyte activation.  Inhibition of the interaction between PD-1 and its 
ligands promotes immune responses and antigen-specific T-cell responses to both foreign 
antigens as well as self-antigens.  Nivolumab has recently shown clinical efficacy in numerous 
cancers, including melanoma, renal cell carcinoma, NSCLC, Hodgkin lymphoma, and others. 
 
Recent studies have also conclusively demonstrated that combining ipilimumab, an inhibitor of 
cytotoxic T lymphocyte antigen-4, increases the response rate and progression free survival in 
patients with metastatic melanoma.  The response rate was 58% vs. 43% vs. 19% for the 
combination, nivolumab, and ipilimumab respectively (p<0.001), while median PFS was similarly 
improved (median 11.5 vs. 6.9 vs. 2.9 months, p<0.001)1.  Overall survival was also increased 
numerically (58% vs. 52% at 3 years), although this was not statistically significant2.  Still, the 
same limitations of intrinsic and acquired resistance still occur, limiting the effectiveness of therapy 
in many patients. 
 
Despite the activity of nivolumab and ipilimumab + nivolumab in these studies, markers to 
prospectively identify patients most likely to respond are needed.  Early studies suggested that 
expression of PD-L1 was required for response to nivolumab3, however subsequent studies have 
not confirmed this.  Importantly, when PD-L1 was examined in patients treated with nivolumab or 
ipilimumab+ nivolumab, no difference in PFS was observed.  This contrasted with patients with low 
PD-L1 expression, which correlated with improved PFS in the combination.  However, overall 
survival was not statistically different in either group, and response rate was superior for the 
combination in both groups.  Overall, PD-L1 positivity correlates with response to therapy, but 
does not allow accurate response prediction.  Thus, better predictive biomarkers are needed to 
stratify patients to immunotherapy treatment, particularly in the first-line setting. 
 
Nivolumab and relatlimab has also demonstrated efficacy in patients with advanced melanoma. 
Among heavily pre-treated patients, all of which had previously failed single-agent anti-PD-1 
therapy, a response rate of 11.5% was observed (7 of 61), with a disease control rate of 49%.  
Biomarker analyses suggested that subjects whose TIL expressed more LAG-3 had a higher 
response rate, with a greater than 3-fold increase in ORR observed in subjects with evidence of 
LAG-3 expression in at least 1% of nucleated cells within the tumor margin, compared to less than 
1% LAG-3 expression (18.2% [6/33] and 5.0% [1/20], respectively).  PD-L1 expression did not 
appear to enrich for response. 
 
3.2.  Rationale for Ipilimumab and Nivolumab in Melanoma 
Ipilimumab and nivolumab in combination have demonstrated efficacy in several trials in advanced 
melanoma.  Checkmate-065, a randomized phase II study, showed that the combination improved 
outcomes compared with single agent ipilimumab in BRAF wild type, metastatic melanoma.  The 
response rate (61% vs. 11%), and median PFS (not reached vs. 4.4 months) were substantially 
improved with monotherapy, leading to an initial approval for this combination in BRAF wild type 
melanoma4.  The efficacy of the combination was then confirmed in Checkmate-067, a phase III 
study comparing nivolumab, ipilimumab, and the combination of both. This study confirmed 
superior response rates for the combination and anti-PD-1 compared to ipilimumab (58%, 44%, 
and 19%), as well as superior PFS (median 11.5 vs. 6.9 vs. 2.5 months)1. 
 
The safety profile of ipilimumab and nivolumab has been acceptable.  Immune-related adverse 
events are increased compared with either monotherapy (59% grade 3-4 treatment related events 
compared with 21% and 28% with nivolumab and ipilimumab, respectively) (See Table 1).  
However, treatment related deaths are rare, and most toxicities resolved with steroid 
administration or other immunosuppressive treatments1.

3.3.  Rationale for Nivolumab and Relatlimab in Melanoma 
Relatlimab (also referred to as BMS-986016, BMS-986016-01, and anti-lymphocyte activation 
gene 3 [LAG-3]) is a fully human LAG-3-specific IgG4 antibody.  Relatlimab binds to the LAG-3 
receptor with high affinity, and thus blocks LAG-3 interactions with its known ligand, major 
histocompatibility complex (MHC) Class II, which is the peptide antigen presentation molecule 
recognized by CD4+ T cells.  Relatlimab binding inhibits the negative regulatory function of LAG-3 
in vitro.  By blocking the downregulatory pathway, relatlimab enhances the anti-tumor immune 
response and, thus, has the potential to inhibit the growth of multiple malignancies when 
administered as a single agent or in combination with other therapeutic immuno-oncology (IO) 
monoclonal antibodies (mAbs).  Using surrogate antibodies recognizing mouse LAG-3 (C9B7W 
and 19C7), anti-tumor activity mediated by LAG-3 blockade has been demonstrated in 3 murine 
syngeneic in vivo tumor models (Sa1N fibrosarcoma, MC38 colon adenocarcinoma, and A20 B-
cell lymphoma).  Both tumor inhibition and the number of tumor-free mice were increased by anti-
LAG-3 monotherapy, while the combination of anti-LAG-3 with a blocking anti-programmed cell 
death protein 1 (PD-1) antibody provided enhanced anti-tumor activity higher than the activity of 
either agent alone and higher than the activity of anti-cytotoxic T-lymphocyte-associated protein 4 
(CTLA-4) antibody in some mice.  Several other studies have clearly demonstrated the role of 
LAG-3, and the additive effects of PD-1 and LAG-3 blockade both in pre-clinical models of cancer 
and chronic infection. 
 
Single agent studies using relatlimab (CA224020 and CA224022) demonstrated partial responses 
in non-small cell lung cancer and marginal zone lymphoma, with numerous other patients showing 
stable disease.  Relatlimab in combination with nivolumab has shown the capacity to induce 
responses in previously heavily treated advanced solid tumors, with the added ability to trigger 
responses in tumors that have demonstrated resistance to nivolumab therapy.  As of the cutoff 
date of 15-Jun-2017 for Part B of Study CA224020, in subjects treated with relatlimab and 
nivolumab combination therapy, partial responses were seen in subjects with melanoma, cervical 
cancer, NSCLC, and squamous cell carcinoma of the head and neck (SCCHN).  As of the cutoff 
date of 07-Apr-2017 for Study CA224022 in subjects treated with relatlimab and nivolumab 
combination therapy, partial responses have been seen in subjects with relapsed/refractory 
Hodgkin lymphoma, with stable disease observed in 1 subject for 6 months (and treatment was 
continuing).  In subjects with melanoma treated with relatlimab and nivolumab combination 
therapy in Part C of Study CA224020, the overall objective response rate (ORR) was 11.5% (7/61, 
response evaluable) with a disease control rate of 49%. Biomarker analyses suggested that

subjects whose TIL expressed more LAG-3 had a higher response rate, with a greater than 3-fold 
increase in ORR observed in subjects with evidence of LAG-3 expression in at least 1% of 
nucleated cells within the tumor margin, compared to less than 1% LAG-3 expression (18.2% 
[6/33] and 5.0% [1/20], respectively).  PD-L1 expression did not appear to enrich for response. 
 
The safety profile of nivolumab + relatlimab has been largely similar to nivolumab monotherapy. 
LAG-3 knockout in mice has minimal effects, but combination PD-1 and LAG-3 knockout leads to 
multiorgan autoimmunity.  This result has not been recapitulated in humans.  Overall, among 304 
patients treated with this combination, 157 (51.6%) had at least one treatment related event, most 
commonly fatigue (12.2%), diarrhea (6.6%; grade 3 in 1%), pruritus (6.9%), and infusion reaction 
(5.9%). One patient had a grade 5 event (myocarditis); 10.2% had grade 3-4 toxicities.

3.4.  Rationale for Flat Dosing of Nivolumab Monotherapy 
Nivolumab monotherapy has been extensively studied in a number of tumor types including 
NSCLC, melanoma, RCC, and CRC with body weight normalized dosing (mg/kg).  Nivolumab 
pharmacokinetics (PK) and exposures of subjects in these studies have been characterized by 
population pharmacokinetic (PPK) analysis of data collected these studies, together with PK data 
from several phase 1, 2, and 3 clinical studies of nivolumab monotherapy in solid tumors.  
Population PK (PPK) analyses have shown that the PK of nivolumab are linear, with dose 
proportional exposures over a dose range of 0.1 mg/kg to 10 mg/kg, and are similar across tumor 
types.  Nivolumab clearance and volume of distribution were found to increase with increasing 
body weight, but the increase was less than proportional, indicating that a mg/kg dose represents 
an over-adjustment for the effect of body weight on nivolumab PK.  Given the relationship between 
nivolumab PK and body weight, a flat dose is expected to lead to lower exposures in heavier 
patients, relative to the exposures in lighter patients. 
 
Using the PPK model, nivolumab steady-state trough, peak and time-averaged concentration 
(Cminss, Cmaxss, and Cavgss, respectively) were predicted for a flat nivolumab dose of 240 mg Q2W 
and compared to those following administration of 3 mg/kg Q2W in NSCLC subjects.  A dose of 
240 mg nivolumab is identical to a dose of 3 mg/kg for subjects weighing 80 kg, which is the 
approximate median body weight of NSCLC subjects in the 3 Phase 2 and 3 BMS clinical studies 
of nivolumab monotherapy.  The geometric mean values of Cminss, Cmaxss, and Cavgss with flat 
dosing are slightly (< 15%) higher than that produced by a 3 mg/kg dose, and the coefficient of 
variation (cv%) in these measures of exposure are only slightly (< 10%) greater than that of 3 
mg/kg dosing.  
 
Across the various tumor types in the BMS clinical program, nivolumab has been shown to be safe 
and well tolerated up to a dose level of 10 mg/kg, and the relationship between nivolumab 
exposure produced by 3 mg/kg and efficacy has been found to be relatively flat.  Taken together, 
the PK, safety, and efficacy data indicate that the safety and efficacy profile of 240 mg nivolumab 
will be similar to that of 3 mg/kg nivolumab. 
 
3.5.  Rationale for Using Major Histocompatability Class II (MHC-II) for Treatment 
Stratification 
MHC-II expression is typically restricted to professional antigen presenting cells such as dendritic 
cells.  In this context, these molecules present antigens to CD4+ Helper T cells to promote 
immune responses.  By contrast, MHC class I molecules are ubiquitous across all nucleated cell 
types, present antigens to cytotoxic, CD8+ T cells.  Given the known critical role of tumor cell 
killing by cytotoxic T cells, most studies historically have examined the role of MHC-I in tumors as 
opposed to MHC-II. 
 
It has been well known, however, that a subset of tumors across the cancer spectrum expresses 
MHC-II, although the mechanism of this finding has not been well-understood.  We observed that 
MHC-II expression in breast cancer correlated with T cell infiltration and improved clinical 
outcomes compared to MHC-II negative tumors.5  More importantly, we published a strong 
correlation between MHC-II expression and response to anti-PD-1 monotherapy (Figure 1).6  In 
discovery and validation cohorts, response rates were improved in the MHC-II populations (79% 
and 75% vs. 38% and 27%; p=0.01 and 0.03, respectively).  PFS and OS were also superior in the 
MHC-II expressors (median PFS not reached vs. 3.2 months, p=0.02); median OS not reached vs. 
27.5 months, p = 0.003).  In addition, expression of MHC-II strongly correlated with improved 
outcomes in Hodgkin lymphoma patients treated with nivolumab.7  An additional independent 
cohort using multiparameter immunofluorescence assessment also demonstrated improved 
clinical outcomes in patients with high expression of MHC-II.8  Thus, multiple independent cohorts 
have confirmed the benefits of anti-PD-1 therapy in tumors with high expression of MHC-II.

II expression.  (E) Correlation matrix of IHC markers.  P values for the Pearson's correlation appear 
above the diagonal and correlation coefficients (r) appear below the diagonal. 
 
 
We performed several studies to explain this finding mechanistically.  MHC-II positive cell lines 
were enriched for gene signatures including the previously defined “PD-1 signaling,” “allograft 
rejection,” and “T cell receptor signaling.”  Importantly, MHC-II positive tumors were also highly 
infiltrated with CD4+ and CD8+ T cells.6  Gene expression signatures for MHC-II positive tumors 
were also enriched with interferon-γ gene signatures and immune checkpoint molecules.  To 
understand the functional role of MHC-II, we enforced the master regulator of MHC-II expression, 
CIITA in a murine cancer model.  Notably, enforced CIITA tumors were rejected by the mice at a 
higher rate than control tumors (Figure 2A).  Those that did establish had higher immune cell 
infiltrate with both CD4+ and CD8+ T cells.  Importantly, LAG3, a cognate antigen and antagonist 
of MHC-II, was also highly expressed in the MHC-II expressing mouse tumors as well (Figure 2B). 
Increased expression of LAG-3 was also observed in human melanomas that developed acquired 
resistance to anti-PD-1 (Figure 2C).  Combination blockade of LAG-3 and PD-1 was particularly 
active in this subpopulation, suggesting that LAG-3 may counteract the pro-immune effects of 
MHC-II (Figure 2D).  This suggests that 1) MHC-II plays a functional role in anti-PD-1 mediated T 
cell rejection of tumors; 2) LAG-3 mediates resistance to anti-PD-1, at least in part; and 3) Co-
targeting MHC-II positive tumors by LAG-3 and PD-1 blockade may be synergistic.

MHC-II negative (Puro), demonstrating high response rates for combination treatment in MHC-II 
positive mouse tumors (pink line). 
 
By contrast, MHC-II non-expressing tumors have less evidence of adaptive immunity and T cell 
infiltration, particularly CD4+ T cells.  Thus, we hypothesize that the combination of ipilimumab and 
nivolumab will augment CD4+ T cell help and overcome the limitations of PD-1 targeting alone.

3.6.  Rationale for Permitting Continued Treatment in Select Cases of Progressive 
Disease 
Accumulating clinical evidence indicates some subjects treated with immune system stimulating 
agents may develop progression of disease (by conventional response criteria) before 
demonstrating clinical objective responses and/or stable disease.  This phenomenon was 
observed in up to 10% of patients treated with nivolumab or pembrolizumab, and also with 
ipilimumab monotherapy.9,10  Two hypotheses have been put forth to explain this phenomenon.  
First, enhanced inflammation within tumors could lead to an increase in tumor size which would 
appear as enlarged index lesions and as newly visible small non-index lesions.  Over time, both 
the malignant and inflammatory portions of the mass may then decrease leading to overt signs of 
clinical improvement.  Alternatively, in some individuals, the kinetics of tumor growth may initially 
outpace anti-tumor immune activity.  With sufficient time, the anti-tumor activity will dominate and 
become clinically apparent.  Therefore, subjects will be allowed to continue study therapy after 
initial investigator-assessed RECIST 1.1 defined progression if they are assessed to be deriving 
clinical benefit and tolerating study drug (Section 9.8).  Such subjects must discontinue study 
therapy upon evidence of further progression. 
 
3.7.  Rationale for Primary Endpoint 
The primary endpoint for this study is change in CD8+ T cell infiltration.  Several studies have 
demonstrated influx of CD8+ T cells as demonstrating immunologic recognition and targeting, and 
as an early surrogate for treatment response.11,12  For example, one study demonstrated that 
expression of CD8 in early on-treatment biopsies was completely non-overlapping in responders 
compared with non-responders.11  Thus, this metric can serve as an accurate surrogate of 
immunologic recognition and tumor responses, and is likely more reliable than a metric such as 
complete pathologic response, particularly in the setting of bulky tumors that may require 
additional time for complete regression.  In addition, in this signal finding phase II study, we are 
evaluating two arms with likely active treatments in parallel, rather than comparing these 
interventions.  Sample size is further based on doubling of CD8+ T cell infiltration from analysis of 
responding patients in two studies, with a standard deviation of 1000.11,12 
 
3.8.  Research Hypotheses 
Patients with MHC-II expressing melanomas will have high rates of change in activated GZMB+      
CD8+ T-cell density intratumorally with nivolumab and relatlimab therapy; MHC-II expression is an 
effective stratifying marker in melanoma that can be used in future studies to select optimal 
treatment.

Prior malignancy active within the previous 3 years currently requiring treatment except for 
locally curable cancers that have been apparently cured, such as basal or squamous cell skin 
cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast. 
 
15. 
Prisoners or participants who are involuntarily incarcerated. 
 
16. 
Participants who are compulsorily detained for treatment of either a psychiatric or physical 
(e.g. infectious disease) illness. 
 
17. 
Psychological, familial, sociological, or geographical conditions that potentially hamper 
compliance with the study protocol and follow-up schedule; those conditions should be 
discussed with the participant before registration in the trial. 
 
 
5.3.  Inclusion of Underrepresented Populations 
Women and men of all races and ethnic groups are eligible for this trial.  There is no bias towards 
gender, age, or race in the clinical trial outlined. 
 
 
5.4.  Number of Patients and Replacement of Patients Who Discontinue Early 
Approximately 36 evaluable patients with advanced melanoma are anticipated to enroll in this 
study at Vanderbilt University Medical Center and approximately two additional academic medical 
centers in the U.S. 
 
In general, it intended that patients will be treated until confirmed disease progression or 
intolerable toxicity.  The criteria for patient discontinuation are listed in Section 9.9.   
 
If a patient discontinues protocol treatment in the first cycle for reasons clearly not related to 
protocol treatment after completing fewer than 1 planned cycle of study therapy, then that patient 
will be considered not evaluable for toxicity and will be replaced with a new patient.

6.  ENROLLMENT PROCEDURES 
 
The Vanderbilt-Ingram Cancer Center (VICC) Coordinating Center will coordinate enrollment in the study. 
 
Prior to registration, a copy of the IRB approval at the site will be kept on file at the Vanderbilt-Ingram 
Cancer Center (VICC) Coordinating Center.  Eligible participants will be entered on study centrally at the 
VICC Coordinating Center.  All sites should email the Coordinating Center at 
Coordinating.Center@vumc.org to verify slot availability prior to enrollment. 
 
All patients MUST be registered with the VICC Coordinating Center prior to the start of protocol 
treatment.  Registration can only be conducted during the business hours of 8AM – 5PM Central 
Time, Monday through Friday. 
 
1) All sites must email the VICC CTSR Coordinating Center at Coordinating.Center@vumc.org 
to notify of upcoming registration and ensure slot availability.  The following information 
should be included in this email: 
 
• 
Study number. 
 
• 
Patient initials. 
 
• 
Disease type. 
 
• 
Anticipated consent date. 
 
• 
Anticipated start date. 
 
2) If a subject ID number is required prior to patient enrollment (i.e. at screening due to sample 
collection requirement), the site must submit the following documents with their email 
notification to the Coordinating Center: 
 
• 
Copy of the patient’s signed and dated Informed Consent including 
documentation of the consent process. 
 
• 
HIPAA authorization form (if separate from the main consent form). 
 
• 
VICC Patient Enrollment Form. 
 
The Coordinating Center will then provide a subject ID number via email. 
 
3) Email the following documents to the Coordinating Center for eligibility review and patient 
enrollment (Coordinating.Center@vumc.org): 
 
• 
Copy of the patient’s signed and dated Informed Consent, including 
documentation of the consent process. 
 
• 
HIPAA authorization form (if separate from the main consent form). 
 
• 
VICC Patient Enrollment Form. 
 
• 
Eligibility supporting documents such as pathology reports, laboratory tests, etc. 
or EMR access.  Note: all source documents should be de-identified and 
screening/subject ID number added prior to sending. 
 
• 
Tissue Block Registration Form (see the Lab Manual).

• 
Signed and completed Eligibility Checklist.  To be eligible for registration to 
the study, the participant must meet each inclusion and exclusion criterion 
listed in the eligibility checklist. 
 
Note:  All study documents should be received 24-48 hours prior to the patient’s anticipated start date.  
Same day treatment registrations will only be accepted with prior notice and discussion with the 
Coordinating Center.  Please email the Coordinating Center if enrollment is needed sooner. 
 
Upon satisfactory review of eligibility documents submitted, the Coordinating Center will approve 
enrollment and issue a subject ID number if one was not issued at screening.  Once 
registration/enrollment confirmation from Coordinating Center is received, proceed with protocol 
procedures. 
 
Please contact the assigned Study Contact with any questions regarding this process.  You can also 
reach out to your assigned CRA once the study is activated. 
 
The VICC Coordinating Center will assign Subject ID numbers to all patients whose eligibility has been 
confirmed.  Only patients deemed eligible will be registered to investigational treatment.  Sequence/study 
ID numbers will not be re-used if a patient screen fails.  Following registration, eligible participants should 
begin study treatment consistent with the protocol no later than 7 days after registration/enrollment by the 
VICC Coordinating Center.  If a participant does not receive protocol therapy following registration within 
the allowed time period, the participant’s registration on the study will be canceled.  The Study Contact 
should be notified of cancellations as soon as possible.  Patients being re-screened will need to consent 
to repeated procedures.  As such, the Coordinating Center will require a new, signed Informed Consent 
document. 
 
Issues that would cause treatment delays should be discussed with the sponsor-investigator.  Any 
requests for eligibility exceptions and/or deviations must be approved in writing by the sponsor-
investigator and the Vanderbilt-Ingram Cancer Center Data and Safety Monitoring Committee (VICC 
DSMC). 
 
As is generally accepted, standard of care procedures performed prior to consent, but within the protocol 
defined screening window for each assessment, can be used for study purposes.  All research-only 
procedures must be performed after patient consent.

Study Calendar Notes: 
 
1. 
Informed Consent:  Informed consent must be obtained before any study-specific screening assessments 
are performed.  Screening assessments are to be performed within 14 days prior to Day 1 of Cycle 1 unless 
otherwise noted (e.g. baseline CT or MRI scan acceptable ≤ 28 days prior to initiating protocol-indicated 
treatment).  Assessments performed as standard of care within the screening window may be used for 
screening.  Baseline characteristics include but are not limited to: demographics, medical and surgical 
history, extent of disease, prior anti-cancer treatment, and tumor histology.   
 
2. 
Vital Signs:  Vital signs to include:  Heart rate (HR), blood pressure (BP), and temperature (oral or 
tympanic).  On each day of treatment, Pre-Dose and Post-Dose vitals must be respectively recorded ≤ 30 
minutes prior to the start of treatment, and ≤ 30 min after the end of each separate treatment.  (Thus, on Day 
1 of each cycle in Arm A, a minimum of 3 sets of vital signs are scheduled to be recorded: Pre-nivolumab, 
Post-nivolumab and Post-relatlimab.  In Arm B, on Day 1 of each of the first four cycles, a minimum of 3 sets 
of vital signs are scheduled to be recorded: Pre-nivolumab, Post-nivolumab, and Post-ipilimumab.  For Arm 
B cycles 5 onward, a minimum of 2 sets of vital signs are scheduled to be recorded: Pre-nivolumab and 
Post-nivolumab.) 
 
3. 
Weight:  Weight at Screening; prior to every dose of nivolumab/relatlimab or nivolumab/ipilimumab (at least 
on same day as treatment); and at the EOT, 30-day, and 100-day Follow-up visits.  In Arm B:  Each of the 
first 4 doses of nivolumab and ipilimumab (scheduled for administration on Day 1 of Cycles 1-4) must be 
adjusted if patient’s body weight changes > ±10% from the weight used to calculate the dose (Section 8.4). 
 
4. 
Concomitant Medications (CMs) and Adverse Events (AEs):  Review and capture of all concomitant 
medications will be performed as indicated.  Concomitant medications include prescription medications and 
over-the-counter preparations used by a patient within at least 14 days prior to first dose of protocol-defined 
treatment and continuing at least through the 30-day Follow-up visit (or until initiation of subsequent 
anticancer therapy).  Adverse events will be collected as detailed in protocol Section 13. 
 
5. 
Hematology:  Hematology includes white blood cell count with differential, hemoglobin, hematocrit, and 
platelet count.   
 
6. 
Serum Chemistries:  Blood Chemistry to include sodium, potassium, chloride, bicarbonate or carbon dioxide, 
blood urea nitrogen (BUN), creatinine, glucose, total bilirubin, AST, ALT, alkaline phosphatase (ALP), 
calcium, albumin, total protein; and magnesium and phosphorus.  
 
7. 
Pregnancy Test:  For women of childbearing potential (see Appendix 4 for definition of WOCBP):  Serum 
pregnancy test required during Screening; and either serum or urine pregnancy test required ≤ 72 hours 
prior to first dose of protocol-indicated treatment (unless serum pregnancy test during screening was already 
done ≤ 72 hours prior to initiating c1d1 treatment) and at the EOT and 30-day Follow-up visits.  
 
8. 
Electrocardiogram (ECG):  For patients stratified to Arm A:  One standard 12-lead electrocardiogram (ECG) 
using local site equipment completed ≤ 28 days before initiation of protocol treatment.  Per Section 8.9, the 
corrected QT interval (QTc) will be calculated using the method of Fridericia (QTcF).  Additional ECGs to be 
performed every 2 weeks for the first 2 months – i.e. on Days 1 and 15, of Cycles 1 and 2.  (On Cycle 1, Day 
1, ECG required for Arm A need not be repeated if already done ≤ 14 days prior to c1d1.) 
 
9. 
Computed Tomography (CT) / Magnetic Resonance Imaging (MRI):  Baseline evaluation of disease status 
by CT or MRI ≤ 28 days prior to initiating protocol treatment on Cycle 1, Day 1.  Baseline and subsequent 
scans to include imaging coverage of anatomical regions as outlined in Section 8.11.  Re-scanning to occur 
every 12 weeks (minus 1-7 days) after initiating protocol treatment on Cycle 1, Day 1.  [The minus 1-7 day 
scan window is intended for flexibility in scheduling re-scans between Days 22-28 of Cycles 3, 6, 9, etc  of 
every third cycle in Arm A; between Days 15-21 of Cycle 4 in Arm B; and then between Days 22-28 of 
Cycles 7, 10, 13, etc of every third cycle in Arm B]. 
 
Scanning on the same day as Day 1 of a new cycle is discouraged but allowed, provided scan results 
receive appropriate RECIST review prior to initiating the new cycle of study treatment.  Additional disease 
evaluations or increased scan frequency may be performed according to the medical judgment of the 
patient’s study physician, in accordance with the following:  In the event of suspected Progressive Disease 
(PD), a CT/MRI is to be performed as soon as possible.  In the event of a Complete or Partial Response

(CR/PR), a confirmatory CT/MRI is to be performed no earlier than 28 days after the first assessment of 
CR/PR. 
 
10. Required Baseline Tumor Tissue:  Archival tissue [paraffin block(s) or unstained slides from paraffin 
block(s)] from the primary tumor and/or a metastatic site must be available prior to initiating treatment, or 
patient must be willing to undergo a fresh pre-treatment standard of care tumor biopsy.  Physical possession 
of requested tissue is required prior to initiating study treatment because all patients in this study are being 
stratified by MHC-II status, based on centralized testing performed at Vanderbilt. 
 
11. Acceptability of Select Screening Items for Cycle 1, Day 1 (c1d1):  On c1d1, Physical Exam, ECOG 
Performance Status; and laboratories designated as Hematology, Serum Chemistries or as “Additional 
Labs” in Section 7.2 (Arm A) and Section 7.3 (Arm B) need not be repeated if already resulted ≤ 7 days prior 
to first dose of protocol-indicated treatment.  In women of childbearing potential (WOCBP), serum or urine 
Pregnancy Test required ≤ 72 hours prior to first dose of protocol-indicated treatment (unless serum 
pregnancy test during screening already completed ≤ 72 hours prior to first dose of protocol-indicated 
treatment). 
 
12. Biomarker and Pharmacodynamic (PD) Blood:  Exploratory blood samples for biomarker and possible PD 
research to be obtained on days as indicated (collected Pre-Dose at a single time point, prior to initiating any 
pre-treatment or protocol-indicated study treatment); and at the EOT and 30-day Follow-up visits.  On days 
when these samples are scheduled to occur on same day as on-study biopsy (i.e. c2d15 in Arm A, and c3d1 
in Arm B), every reasonable effort should be made to collect this blood PRIOR to biopsy procedure. 
 
13. Nivolumab Infusion (Arm A and Arm B):  The study will supply Nivolumab to the site.  All patients are 
scheduled to receive nivolumab as a 30 minute (±10 minute) intravenous infusion.   
 
In Arm A:  On Day 1 of each 28-day cycle, nivolumab will be completed BEFORE initiation of relatlimab. 
In Arm B:  On Day 1 of each 21-day cycle (i.e. Cycles 1-4), nivolumab will be completed BEFORE initiation 
of ipilimumab.  Starting with Cycle 5, nivolumab will be administered on Day 1 of each cycle as 
monotherapy. 
 
14. Relatlimab Infusion (Arm A):  The study will supply relatlimab to the site.  On Day1 each 28-day cycle, all 
patients in Arm A are scheduled to receive relatlimab as a 60 minute (±10 minutes) intravenous infusion. 
 
15. Ipilimumab Infusion (Arm B):  The study will supply Ipilimumab to the site.  On Day 1 of each 21-day cycle 
(i.e. Cycles 1-4), all patients in Arm B are scheduled to receive ipilimumab as a 90 minute (±10 minutes) 
intravenous infusion, for a maximum of four total doses of ipilimumab. 
 
16. Administrative Scheduling Window:  Beginning with Cycle 2, Day 1: Up to 3 days delay (i.e. plus 1 to 3 days; 
but not minus 1 to 3 days) in the initiation of Day 1 of a new cycle, will be permitted in order to facilitate 
holidays, weekends, bad weather, scheduling, or other unforeseen circumstances not including adverse 
events.  Such administrative delay – not to be used for adverse event management – will not be considered 
a protocol deviation. 
 
17. Scheduling Flexibility for On-Study Laboratory Items:  For all cycles, beginning with Cycle 2, Day 1:  
Laboratories designated as Hematology, Serum Chemistries or as “Additional Labs” in Section 7.2 (Arm A) 
and Section 7.3 (Arm B) need not be repeated on days of treatment, if already resulted ≤ 3 days prior to 
treatment. 
 
18. End-of-Treatment (EOT) Visit:  Reasonable effort should be made to complete End-of-Treatment (EOT) 
procedures on the day it is decided a patient will no longer receive protocol-indicated treatment.  These 
procedures must be completed subsequent to and not later than 14 days after investigator decision to 
permanently discontinue protocol-indicated treatment with nivolumab, relatlimab or ipilimumab (whichever 
treatment occurs last) and prior to any subsequent anti-cancer therapy. 
 
19. Concluding Disease Assessments:  At End-of-Treatment (EOT), CT/MRI required only if the previous 
CT/MRI was done >28 days before.  At the 30-day Follow-Up visit, CT/MRI required only if disease 
progression was not already documented by CT/MRI done before, during or after the prior EOT visit.  If a 
patient discontinues the study for reason other than progressive disease confirmed by CT or MRI (e.g. 
adverse event), then CT or MRI scans involving sites of known or suspected disease must be continued (if 
clinically feasible) every 12 weeks (± 7 days) for 12 months and then approximately every 24 weeks (± 4 
weeks) thereafter, relative to date(s) of prior scanning, until disease progression is confirmed by imaging.

(Note:  If the patient initiates treatment in another clinical trial, then any continuing scans done for this trial 
may terminate.) 
 
20. 30-day and 100-day Follow-up Visits:  Follow-up clinic visits are to be completed 30-37 days and 100-114 
days after patient’s final protocol-indicated treatment with nivolumab, relatlimab or ipilimumab (whichever 
occurs last).  Documented attempt(s) should be made for patient return to the study clinic.  It will not be 
considered a protocol deviation if the patient is physically unable to return for the follow-up visit; such 
circumstance should be recorded in the study documents, and as much of the follow-up information as 
possible should be obtained via feasible patient contact and from local and outside facilities. 
 
21. Survival and Long-Term Follow-up:  Each patient will be followed for survival and information about 
subsequent anticancer therapy every 12 weeks (3 months) ±14 days after patient’s final protocol treatment 
with nivolumab, relatlimab or ipilimumab (whichever occurs last) until death, termination of the study, patient 
withdraws consent, or for a maximum of 2 years after the patient’s final protocol-indicated treatment – 
whichever comes first.  Contact can be made via clinic visit, chart review, obituary or similar observation 
(e.g. Social Security death index), or by telephone.

Documented attempt(s) should be made for patient return to the study clinic.  It will not be 
considered a protocol deviation if the patient is physically unable to return for the 30-day and 100-
day follow-up visits; such circumstance should be recorded in the study documents, and as much 
of the follow-up information as possible should be obtained via feasible patient contact and from 
local and outside facilities. 
 
A follow-up clinic visit is to be completed 30-37 days after patient’s final protocol-indicated 
treatment with nivolumab, relatlimab or ipilimumab (whichever occurs last), in order to undergo the 
following assessments: 
 
• 
Physical Exam.

A follow-up clinic visit is to be completed 100-114 days after patient’s final protocol-indicated 
treatment with nivolumab, relatlimab or ipilimumab (whichever occurs last), in order to undergo the 
following assessments: 
 
• 
Physical Exam. 
 
• 
Vital Signs:  Heart rate (HR), blood pressure (BP), and temperature. 
 
• 
ECOG Performance Status. 
 
•

• 
Adverse Event review. 
 
If a patient discontinues the study for reason other than progressive disease confirmed by CT or 
MRI (e.g. adverse event), then CT or MRI scans involving sites of known or suspected disease 
must be continued (if clinically feasible) every 12 weeks (± 7 days) for 12 months and then 
approximately every 24 weeks (± 4 weeks) thereafter, relative to date(s) of prior scanning, until 
disease progression is confirmed by imaging.  (Note:  If the patient initiates treatment in another 
clinical trial, then any continuing scans done for this trial may terminate.) 
 
7.17.  Survival and Long-Term Follow‐Up 
Each patient will be followed for survival and information about subsequent anticancer therapy 
every 12 weeks (3 months) ±14 days after patient’s final protocol treatment with nivolumab, 
relatlimab or ipilimumab (whichever occurs last) until death, termination of the study, patient 
withdraws consent, or for a maximum of 2 years after the patient’s final protocol-indicated 
treatment – whichever comes first.  Contact can be made via clinic visit, chart review, obituary or 
similar observation (e.g. Social Security death index), or by telephone.  Outside of this intended 
schedule, the sponsor-investigator and/or BMS may also request that survival data be collected on 
all treated subjects.  At that time of this request, each subject will be contacted by similar means to 
determine their survival status unless the subject had withdrawn consent for all contact.

8.  STUDY PROCEDURES 
 
8.1.  Informed Consent 
Informed consent must be obtained before any study-specific screening assessments are 
performed.  Screening assessments are to be performed within 14 days prior to Day 1 of Cycle 1 
unless otherwise noted (e.g. baseline CT or MRI scan allowed up to 28 days prior to initiating 
Cycle 1, Day 1 treatment).  Assessments performed as standard of care within the screening 
window may be used for screening.  Baseline characteristics include but are not limited to:  
demographics, medical and surgical history, extent of disease, prior anti-cancer treatment, and 
tumor histology. 
 
8.2.  Physical Examination and ECOG Performance Status 
Physical examination and assessment of Eastern Cooperative Oncology Group (ECOG) 
performance status to be performed within 14 days prior to initiating protocol treatment; on Cycle 
1, Day 1 (unless previously completed ≤ 7 days prior to a patient’s first dose of protocol-indicated 
treatment), and at additional time points as outlined in Section 7. 
 
8.3.  Vital Signs 
Vital signs to include: Heart rate (HR), blood pressure (BP), and temperature (oral or tympanic). 
 
On each day of treatment with nivolumab/relatlimab or nivolumab/ipilimumab, Pre-Dose and Post-
Dose vitals must be respectively recorded ≤30 minutes prior to the start treatment, and ≤30 
minutes after the end of each separate treatment; thus: 
 
• 
On Day 1 of each cycle in Arm A, a minimum of 3 sets of vital signs are scheduled to be 
recorded: Pre-nivolumab, Post-nivolumab and Post-relatlimab.  
 
• 
In Arm B, on Day 1 of each of the first four cycles, a minimum of 3 sets of vital signs are 
scheduled to be recorded: Pre-nivolumab, Post-nivolumab and Post-ipilimumab.  For Arm 
B cycles 5 onward, a minimum of 2 sets of vital signs are scheduled to be recorded: Pre-
nivolumab and Post-nivolumab. 
 
8.4.  Body Weight 
Weight is measured at screening, prior to every dose of study treatment; and at the EOT, 30-day 
and 100-day Follow-up visits. 
 
Patient’s body weight must be measured at least on the same day in which every dose of 
nivolumab, relatlimab, or ipilimumab is administered to the patient. 
 
In Arm B:  Each of the first 4 doses of nivolumab and ipilimumab (scheduled for 
administration on Day 1 of Cycles 1-4) must be adjusted if patient’s body weight changes  
> ±10% from the weight used to calculate the dose. 
 
8.5.  Review of Concomitant Medications and Adverse Events 
Review and capture of all concomitant medications will be performed at each visit as indicated in 
Section 7.  Concomitant medications include prescription medications and over-the-counter 
preparations used by a patient within at least 14 days prior to first dose of protocol-defined

treatment and continuing through at least the 30-day Follow-Up study visit (or until initiation of 
subsequent anticancer therapy).  Adverse events will be collected as detailed in protocol Section 
13.   
 
8.6.  Complete Blood Count (CBC) with Differential 
Local hematology results at time points indicated in Section 6.1 to include white blood cell count 
with differential, hemoglobin, hematocrit, and platelet count. 
 
8.7.  Blood Chemistry 
Local blood chemistry results at time points indicated in Section 7 to include sodium, potassium, 
chloride, bicarbonate or carbon dioxide, blood urea nitrogen (BUN), creatinine, glucose, total 
bilirubin, AST, ALT, alkaline phosphatase (ALP), calcium, albumin, total protein; magnesium and 
phosphorus. 
 
8.8.  Additional Labs 
Blood draws for additional local laboratory assessment of LDH, TSH, free T3, free T4, cortisol, 
troponin-I, CK, and CK-MB at time points indicated in Section 7.  Designation of “reflexive” in 
Section 7 indicates assessment of free T3 and free T4 only when TSH is not within normal range.  
ACTH, amylase and lipase done as clinically indicated per judgment of the investigator.   
 
8.9.  ECG 
For patients in Arm A: Standard 12-lead electrocardiogram (ECG), single tracing, using local site 
equipment completed during screening for all patients.  Additional single tracing ECGs done prior 
to treatment on days as indicated in Section 7.2.  Additional ECGs as clinically indicated per 
patient’s study physician. 
 
The corrected QT interval (QTc) will be calculated using the method13 of Fridericia (QTcF), where 
QTcF equals the QT interval divided by the cube root of the RR interval: 
 
𝑄𝑄𝑄𝑄𝑄𝑄𝑄𝑄= 𝑄𝑄𝑄𝑄
√𝑅𝑅𝑅𝑅
3
  
 
Note:  During screening, as part of eligibility verification, QTcF > 480 msec is an exclusionary 
criterion (Section 5). 
 
8.10.  Pregnancy Test 
For women of childbearing potential (WOCBP):  Serum pregnancy test required during screening; 
and either serum or urine pregnancy test required ≤ 72 hours prior to first dose of protocol-
indicated treatment (unless serum pregnancy test during screening was already done ≤ 72 hours 
prior to initiating c1d1 treatment), and at the EOT and 30-day Follow-up visits.   
 
See Appendix 4 for study required contraception and definition of WOCBP. 
 
8.11.  Disease Assessment by CT/MRI 
Baseline evaluation of disease status by Computed Tomography (CT) and/or Magnetic 
Resonance Imaging (MRI) ≤ 28 days prior to initiating protocol treatment on Cycle 1, Day 1.

Baseline and subsequent scans to include imaging of the chest, abdomen, and pelvis and CT 
and/or MRI of the brain.  Additional sites of known or suspected disease should be imaged during 
screening and subsequent scans. 
 
Re-scanning to occur every 12 weeks (minus 1-7 days) after initiating protocol treatment on Cycle 
1, Day 1. The minus 1-7 day scan window is intended for flexibility in scheduling. 
 
Additional disease evaluations or increased scan frequency may be performed according to the 
medical judgment of the patient’s study physician, in accordance with the following:  In the event of 
suspected Progressive Disease (PD), a CT/MRI is to be performed as soon as possible.  In the 
event of a Complete or Partial Response (CR/PR), a confirmatory CT/MRI is to be performed no 
earlier than 28 days after the first assessment of CR/PR. 
 
At End-of-Treatment, CT/MRI required only if the previous CT/MRI was done >28 days before. 
 
At the 1M F/U Follow-Up visit, CT/MRI required only if disease progression was not already 
documented by CT/MRI done before, during or after the prior EOT visit. 
 
If a patient discontinues the study for reason other than progressive disease confirmed by CT or 
MRI (e.g. adverse event), then CT or MRI scans involving sites of known or suspected disease 
must be continued (if clinically feasible) every 12 weeks (± 7 days) for 12 months and then 
approximately every 24 weeks (± 4 weeks) thereafter, relative to date(s) of prior scanning, until 
disease progression is confirmed by imaging. 
 
If the patient initiates treatment in another clinical trial, then any continuing scans done for this trial 
may terminate. 
 
8.12.  Required Baseline Tumor Tissue 
Archival tissue [paraffin block(s) or unstained slides from paraffin block(s)] from the primary tumor 
and/or a metastatic site must be available prior to initiating treatment, or patient must be willing to 
undergo a fresh pre-treatment standard of care tumor biopsy.  Within 28 days prior to initiating 
treatment, the screening team must have documentation that an archival or fresh tumor specimen 
has been requested from a local or outside facility.  Physical possession and centralized testing of 
requested tissue is required prior to initiating study treatment because all patients in this study are 
being stratified by MHC-II status, based on centralized testing performed at Vanderbilt. 
 
8.13.  Fresh Tumor Biopsy 
Fresh biopsy of lesion amenable to safe biopsy from a primary lesion or metastatic site, performed 
approximately 6 weeks following initiation of protocol-indicated treatment: 
 
• 
Arm A: Fresh biopsy on Cycle 2, Day 15 (±7 days) 
• 
Arm B: Fresh biopsy on Cycle 3, Day 1 (±7 days). 
 
Note that research blood is also scheduled for collection on these days, and with similar ±7 day 
flexibility, in order that the research blood draws are ideally obtained on the same day as the on-
study fresh biopsy (and ideally PRIOR to the biopsy procedure). 
 
8.14.  Biomarker and Pharmacodynamic (PD) Blood Samples 
Peripheral blood samples for exploratory analysis including biomarker and possible PD research 
to be obtained at time points indicated in Section 7.

45 of 100 
 
Note that 2 of these time points also correspond to days when fresh tumor biopsy is also intended 
(i.e. Cycle 2, Day 15 in Arm A; and Cycle 3, Day 1 in Arm B).  To accommodate scheduling, a ±7 
day window for the fresh on-study biopsy is allowed; therefore, a similar ±7 day window is also 
applicable to the research blood draws scheduled for these two time points, in order for the 
research blood to be collected ideally on the same day as the fresh biopsy (and ideally PRIOR to 
the biopsy procedure).   
 
8.15.  Handling of Biological Samples 
All biological samples to be analyzed locally will be collected and handled according to local 
institutional practices.  All biological samples to be analyzed centrally will be collected and handled 
according to a provided laboratory manual.  Retention time for biologic specimens will be specified 
in the laboratory manual.

9.  PROTOCOL TREATMENT 
 
9.1.  Dose Summary 
 
This is a phase 2, open-label, two-arm study in patients with locally advanced/unresectable or 
metastatic melanoma, evaluating the efficacy of either nivolumab plus relatlimab against MHC-II 
positive tumors (Arm A); or nivolumab plus ipilimumab against MHC-II negative tumors (Arm B).

Every effort should be made to target infusion timings to be as close as possible to the scheduled 
duration.  But given the variability of infusion pumps, time windows of ±10 minutes for the 
scheduled duration of infusions are permitted.  (Additionally, prolongation of infusion duration for 
the purpose of managing suspected or actual adverse event such as infusion reaction will not be 
considered a protocol deviation.) 
 
In Arm B, doses of nivolumab and ipilimumab administered on a mg/kg basis (i.e. all those given 
prior to initiation of flat-dose nivolumab scheduled to begin in Cycle 5 of Arm B) will be determined 
by measuring the patient’s weight in kilograms on the day of dosing, prior initiation of 
nivolumab/ipilimumab.   
 
If the patient’s weight on the day of dosing differs by > ±10% from the weight used to calculate a 
dose based on mg/kg, then doses of nivolumab and ipilimumab must be recalculated prior to 
administration.     
 
In Arm B, unless otherwise specified (e.g. by established institutional practice), all calculated 
doses based on mg/kg may be rounded up (or down) to the nearest milligram; and a ±5% variance 
in the calculated total dose will be allowed for ease of dose administration. 
 
9.2.  Antiemetic Premedication 
Administration of established institutional standard premedication prior to infusion is allowed, 
however it is recommended that antiemetic medications should not be routinely administered prior 
to dosing of drugs.  See Section 11.5 for subsequent premedication recommendations following a 
study drug-related infusion reaction. 
 
9.3.  Nivolumab Infusion 
The study will supply nivolumab to the site. 
 
All patients in this study will receive nivolumab: 
 
• 
Patients in Arm A will receive nivolumab in combination with relatlimab. 
 
• 
Patients in Arm B will receive nivolumab in combination with ipilimumab. 
 
Each patient receiving nivolumab will be treated at the assigned dose as specified in Section 9.1.  
Nivolumab will be administered intravenously consistent with the product label14, as a 30 minute 
(±10 minutes) intravenous infusion. 
 
In Arm A, all nivolumab administrations are scheduled as a flat-dose of 480mg. 
 
In Arm B, a patient’s first 4 doses of 1mg/kg nivolumab will be determined by measuring the 
patient's weight in kilograms on the day of dosing, prior to each nivolumab dose.  If the patient’s 
weight on the day of nivolumab dosing differs by > ±10% from the weight used to calculate the 
dose, then doses of nivolumab (and ipilimumab) must be recalculated prior to administration.   
 
Patients should be carefully monitored for infusion reactions during nivolumab administration.  If 
an infusion-related reaction (IRR) is noted, patients should be managed according to established 
local procedures consistent with the product label14 and Section 11.5. 
 
For purpose of adverse event management, doses of nivolumab may be held/delayed for up to 42 
days (6 weeks) from time of the last nivolumab dose (e.g. Section 11.2).

9.4.  Relatlimab (BMS-986016) Infusion 
The study will supply relatlimab to the site. 
 
Patients stratified to Arm A of the study (i.e. tumor tissue MHC-II positive) will receive relatlimab in 
combination with nivolumab. 
 
On Day 1 of each 4 week cycle, patients in Arm A are scheduled to receive SEPARATE 
intravenous infusions of nivolumab and relatlimab: The relatlimab infusion will be started 
AFTER completion of the nivolumab infusion. 
 
Each patient receiving relatlimab will be treated at the assigned dose as specified in Section 9.1.  
Relatlimab will be administered consistent with the investigator’s brochure15, as a 60 minute (±10 
minutes) intravenous infusion. 
For all relatlimab administrations, an appropriate dosing history will be recorded, e.g.: 
 
• 
Total dose administered. 
 
• 
Infusion start and stop time. 
 
• 
Dose interruption or termination and reason for such actions. 
Patients should be carefully monitored for infusion reactions during relatlimab administration.  If an 
infusion-related reaction (IRR) is noted, patients should be managed according to established 
local procedures consistent with the investigator brochure15 and Section 11.5. 
 
For purpose of adverse event management, doses of relatlimab may be held/delayed for up to 6 
weeks from time of the last relatlimab dose (e.g. Section 11.2). 
 
9.5.  Ipilimumab Infusion 
The study will supply ipilimumab to the site. 
 
Patients stratified to Arm B of the study (i.e. tumor tissue MHC-II negative) will receive ipilimumab 
in combination with nivolumab. 
 
In Arm B, combinatorial treatment with nivolumab and ipilimumab is scheduled to be administered 
on Day 1 of four initial cycles lasting 3-weeks per cycle.   
 
Every patient in Arm B of the study is scheduled to receive 4 total doses of nivolumab and 4 total 
doses of ipilimumab in a combinatorial setting.  (In Arm B, after 12 weeks of combinatorial 
treatment with nivolumab + ipilimumab, all patients in Arm B are then scheduled to continue 
nivolumab alone, as monotherapy, in lengthened cycles lasting 4 weeks per cycle.)   
 
After receiving 4 infusions of ipilimumab, ipilimumab treatment will be complete.       
 
Each patient receiving ipilimumab will be treated at the assigned dose as specified in Section 9.1.  
Ipilimumab will be administered intravenously consistent with the product label16, as a 90 minute 
(±10 minutes) intravenous infusion. 
 
In Arm B, on Day 1 of Cycles 1-4:  Patients in Arm B are scheduled to receive SEPARATE 
intravenous infusions of nivolumab and ipilimumab: The ipilimumab infusion will be started 
AFTER completion of the nivolumab infusion. 
 
In Arm B, a patient’s 4 doses of 3mg/kg ipilimumab will be determined by measuring the patient's 
weight in kilograms on the day of dosing, prior to each ipilimumab dose.  If the patient’s weight on

49 of 100 
 
the day of ipilimumab dosing differs by > ±10% from the weight used to calculate the dose, then 
doses of ipilimumab (and nivolumab) must be recalculated prior to administration.   
 
Patients should be carefully monitored for infusion reactions during ipilimumab administration.  If 
an infusion-related reaction (IRR) is noted, patients should be managed according to established 
local procedures consistent with the product label16 and Section 11.5. 
 
For purpose of adverse event management, doses of ipilimumab may be held/delayed for up to 6 
weeks from time of the last ipilimumab dose (e.g. Section 11.2). 
 
9.6.  Nivolumab and Relatlimab (Arm A): Separate Infusions 
When both nivolumab and relatlimab are to be administered on the same day, separate infusion 
bags and filters must be used for each infusion. 
 
Nivolumab is to be administered first. 
 
The nivolumab infusion must be promptly followed by a saline flush to clear the line of nivolumab 
before starting the relatlimab infusion.  
 
The second infusion will be relatlimab and will start after the infusion line has been flushed, filters 
changed, and patient has been observed to ensure no infusion reaction has occurred.  
 
Relatlimab infusion will start within 60 minutes after completion of the nivolumab infusion. 
 
9.7.  Nivolumab and Ipilimumab (Arm B): Separate Infusions 
When both nivolumab and ipilimumab are to be administered on the same day, separate infusion 
bags and filters must be used for each infusion.  
 
Nivolumab is to be administered first.  
 
The nivolumab infusion must be promptly followed by a saline flush to clear the line of nivolumab 
before starting the ipilimumab infusion.  
 
The second infusion will always be ipilimumab and will start no sooner than 30 minutes after 
completion of the nivolumab infusion. 
 
9.8.  Treatment Beyond Disease Progression 
Accumulating evidence indicates a minority of patients treated with immunotherapy may derive 
clinical benefit despite initial evidence of PD10.  Patients will be permitted to continue treatment 
beyond initial RECIST 1.1 defined PD as long as they meet the following criteria: 
 
1) Investigator-assessed clinical benefit, and do not have rapid disease progression 
 
2) Tolerance of study drug 
 
3) Stable performance status 
 
4) Treatment beyond progression will not delay an imminent intervention to prevent serious 
complications of disease progression (e.g. CNS metastases) 
 
5) Patient provides written informed consent prior to receiving any additional nivolumab 
treatment, or nivolumab in combination with ipilimumab treatment, or nivolumab in 
combination with relatlimab 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 patient 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 sponsor-
investigator and documented in writing in advance within the study records.  Patients will be re-
consented with an ICF describing any reasonably foreseeable risks or discomforts. 
 
Patients should discontinue study therapy 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). 
 
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).  Any new lesion considered non-measurable at the time of initial progression may 
become measurable and therefore be included in the tumor burden measurement if the longest 
diameter increases to at least 10 mm (except for pathological lymph nodes, which must have an 
increase in short axis to at least 15 mm). 
 
For statistical analyses that include the investigator-assessed progression date, patients who 
continue treatment beyond initial investigator-assessed, RECIST 1.1-defined progression will be 
considered to have investigator-assessed progressive disease at the time of the initial progression 
event. 
 
9.9.  Discontinuation of Protocol-Indicated Treatment 
In this trial, combinatorial treatment with relatlimab and nivolumab (Arm A) or ipilimumab and 
nivolumab (Arm B) shall be considered separable:  Relatlimab and nivolumab or ipilimumab and 
nivolumab may be permanently discontinued simultaneously; or relatlimab treatment may be 
discontinued before discontinuing nivolumab; or ipilimumab may be discontinued before 
discontinuing nivolumab treatment. 
 
The visit schedule for protocol treatment will apply until permanent discontinuation of both 
nivolumab and relatlimab (in Arm A), or both nivolumab and ipilimumab (in Arm B).  Once 
permanent discontinuation of both drugs has occurred, an End-of-Treatment (EOT) visit will be 
performed within 14 days after the decision to permanently discontinue the last of the two 
treatments (nivolumab and/or relatlimab; or nivolumab and/or ipilimumab), prior to any subsequent 
anti-cancer therapy. 
 
After the EOT visit, the patient will continue to be followed until 30 to 37 days after the last dose of 
protocol-indicated treatment, at which time the one month Follow-Up visit must be completed. 
 
Reasons for permanent discontinuation of a patient’s protocol-indicated treatment include any of 
the following: 
 
• 
Inability to tolerate nivolumab and/or relatlimab (Arm A). 
 
• 
Inability to tolerate nivolumab and/or ipilimumab (Arm B). 
 
• 
Patient withdraws consent to participate. 
 
• 
Occurrence of an AE considered by the investigator to require treatment discontinuation. 
 
• 
Toxicity requiring discontinuation as outlined in Section 11.4. 
 
•

• 
Treatment failure not meeting the criteria for PD, but considered by the investigator to 
require treatment discontinuation (e.g. clinical progression). 
 
• 
Requirement for a significant surgical procedure.  Note: Patients requiring a minor surgical 
procedure (e.g. port placement, skin abscess drainage) may continue at the investigator's 
discretion following discussion with the sponsor-investigator or designee.  A brief 
interruption in therapy may be considered. 
 
• 
An intercurrent illness which, in the opinion of the investigator, would prevent completion 
of trial-related evaluations. 
 
• 
The investigator judges it necessary due to medical reasons (e.g. significant deterioration 
in performance status). 
 
• 
Required use of a prohibited concomitant medication, as defined in Section 10.2.  Note: 
subject to discussion with and approval by the sponsor-investigator, inadvertent isolated 
receipt of a prohibited concomitant medication (e.g. incidental to acute management of an 
adverse event) does not require permanent discontinuation. 
 
• 
The patient becomes pregnant during treatment.  (Cases of pregnancy that occur during 
maternal or paternal exposures to study treatment should be reported as SAEs.  Data on 
fetal outcome and breast-feeding may be collected for regulatory reporting and drug safety 
evaluation.) 
 
• 
Significant deviation from the protocol or eligibility criteria.  Such patients will be 
considered protocol violations and may be discontinued from treatment after discussion 
with the sponsor-investigator. 
 
• 
Noncompliance with trial procedures may require discontinuation after discussion with the 
sponsor-investigator. 
 
• 
Termination of the trial by the sponsor-investigator or regulatory authority. 
 
9.10.  Duration of Follow-Up 
In general, it intended that patients will be treated until disease progression or intolerable toxicity; 
or up to a maximum of 2 years of study treatment.  Criteria for patient discontinuation include 
those listed in Section 11.4.  Patients should be assessed when it is decided the patient will no 
longer receive protocol-indicated treatment; and assessed again 30-37 days after patient’s final 
protocol-indicated treatment with nivolumab, relatlimab or ipilimumab (whichever treatment occurs 
last).  
 
At the end of the study period, Bristol-Myers Squibb Company will not continue to supply study 
drug to subjects/investigators unless the Sponsor-Investigator chooses to extend their study. The 
investigator is responsible to ensure that the subject receives appropriate standard of care or other 
appropriate treatment in the independent medical judgement of the Investigator to treat the 
condition under study. 
 
Subsequently, each patient will be followed for survival every 3 months (± 14 days) after patient’s 
final protocol-indicated treatment until death, end of the study, until patient withdraws consent, or 
for a maximum of 2 years after the patient’s final protocol-indicated treatment with 
relatlimab/nivolumab/ipilimumab – whichever comes first.  Contact can be made via clinic visit, 
chart review, obituary or similar observation (e.g. Social Security death index), or by telephone. 
 
The sponsor-investigator and/or BMS may request that survival data be collected on all treated 
subjects outside of the protocol-defined window.  At that time of this request, each subject will be 
contacted to determine their survival status unless the subject had withdrawn consent for all 
contact.

9.11.  Withdrawal from Study 
Patients may withdraw from the study at any time at their own request, or they may be withdrawn 
at any time at the discretion of the investigator or sponsor-investigator for safety or behavioral 
reasons; or the inability of the patient to comply with the protocol-required schedule of study visits 
or procedures; or an inability to maintain voluntary informed consent.  The EOT and the Follow-Up 
visits should be performed to the extent possible and the Investigator should ensure any SAE is 
followed as described in Section 13. 
 
Reasons for withdrawal from the study might include but are not limited to any of the following: 
 
• 
The patient withdraws consent to participate in treatment, follow-up, or survival monitoring. 
 
• 
The investigator judges it necessary due to medical reasons. 
 
• 
Subject is lost to follow-up. 
 
• 
A maximum of 2 years of survival monitoring elapses after patient’s last dose of protocol-
indicated nivolumab/relatlimab/ipilimumab. 
 
• 
Study is terminated for any reason. 
 
 
10.  CONCOMITANT TREATMENT 
 
10.1.  Supportive Care Guidelines 
Patients may receive their current concomitant medication (CM) and any medication considered 
necessary by the patient’s study physician for the welfare of the patient during the trial, except as 
otherwise restricted or prohibited (for example, if the CM is listed in Section 5 Inclusion/Exclusion 
Criteria, or in Section 10.2).  Furthermore, when used within established institutional guidelines 
(when existent) and/or at study physician’s discretion, the following medications and procedures 
are permitted during the trial: 
 
• 
Palliative radiotherapy for localized pain control against non-target lesions, as long as it is 
not anticipated to significantly influence systemic bone marrow function, Section 10.3. 
 
All concomitant medications should be recorded throughout the patient’s participation in the study, 
including medications taken within at least 14 days prior to first dose of protocol-defined treatment. 
 
Concomitant medications and supportive care therapies must also be documented at the time of 
study discontinuation and at the 30-day follow-up visit. 
 
Appropriate documentation for all forms of premedications, supportive care, and concomitant 
medications (for example, medications such as sedatives, antibiotics, analgesics, antihistamines, 
corticosteroids, erythropoietin; procedures such as paracentesis, thoracentesis; or blood products 
such as blood cells, platelets, fresh frozen plasma transfusions) must be captured on the eCRF. 
 
10.2.  Prohibited Therapies and Procedures 
The following therapies and procedures are not allowed from first visit (Screening) after signing 
consent, or as specified in the inclusion/exclusion criteria (Section 5) until completion of the EOT 
Visit: 
 
• 
Other than nivolumab/relatlimab or nivolumab/ipilimumab, any other anti-cancer treatment, 
including cytotoxic or cytostatic agents, or hormonal therapy (except as otherwise

permitted by protocol – e.g. corticosteroids initiated during the study to manage adverse 
events associated with immunotherapy; or stable doses of corticosteroids established prior 
to study entry for stable CNS metastasis; or anti-estrogen/androgen therapy for select in 
situ malignancies in remission). 
 
• 
Hematopoietic growth factors or transfusions used to meet hematologic criteria for study 
inclusion (Section 5). 
 
• 
Radiotherapy against target lesion(s), Section 10.3. 
 
• 
Although bisphosphonate osteoclast inhibitors (e.g. zoledronic acid or pamidronate) for 
treatment of bone metastases are permitted during study treatment, the osteoclast 
inhibitor denosumab is a monoclonal antibody, which could confound safety analysis in the 
study if the patient experiences a hypersensitivity reaction to denosumab.  Therefore, 
concomitant use of denosumab will not be permitted. 
 
• 
Major surgery that would preclude the patient from complying with the protocol 
requirements. 
 
If any of the above listed medications/procedures becomes necessary during the trial, the patient 
must be withdrawn from treatment and the EOT Visit should be performed.  The 30-day and 100-
day Follow-up visits should then be conducted according to Section 7.4 after the patient’s final 
treatment with nivolumab/relatlimab/ipilimumab (whichever occurs last), and the patient will be 
followed for survival. 
 
10.3.  Concomitant Radiotherapy 
Per study eligibility criteria, prior therapeutic or palliative radiation therapy must be completed  
> 2 weeks prior to first dose of study treatment. 
 
After beginning trial treatment, palliative radiotherapy must be discussed in advance of receipt, in 
writing, with the sponsor-investigator. 
 
Local radiotherapy of isolated lesions with palliative intent (e.g. bleeding, pain, compression, etc.) 
will be permitted if considered medically necessary by the study physician.  The irradiated area 
should be as small as possible, and the total dose delivered must be in a palliative range 
according to institutional standards.  Irradiated lesions will be followed for disease progression but 
will not be accounted for in the evaluation of the response.  Radiotherapy other than palliative 
radiotherapy for symptom control is not allowed concomitantly with the administration of protocol-
indicated treatment.  
 
Patients requiring palliative radiotherapy should be assessed for disease progression.  If palliative 
radiotherapy is needed to control pain, the site(s) of disease causing pain should be present at 
baseline; otherwise, painful lesion(s) requiring radiotherapy should be considered as a sign of 
disease progression. 
 
If palliative radiotherapy is required, then patients should be closely monitored for any potential 
toxicity during and after receiving radiotherapy, and AEs considered related to radiotherapy should 
resolve to Grade ≤1 prior to resuming study treatment. 
 
If a treatment cycle is interrupted for palliative radiation, then the decision to possibly resume 
study treatment will be made by the study physician, with written advance agreement from the 
investigator and the sponsor-investigator.  Continuous interruption of >42 days due to palliative 
radiotherapy will not be allowed. 
 
Only non-target lesions may receive palliative radiotherapy while on trial treatment.  Details of 
palliative radiotherapy should be documented in the source records and eCRF.  Details in the

54 of 100 
 
source records should include: dates of treatment, anatomical site, dose administered and 
fractionation schedule, and AEs. 
 
11.  ADVERSE EVENT MANAGEMENT 
 
Patients should be instructed to notify their study team at the first occurrence of any adverse 
symptom.  In addition to dose delays according to protocol guidance, investigators are encouraged 
to employ best supportive care according to local institutional clinical practice. 
 
Recognizing that new knowledge will be acquired and unforeseen safety issues may arise in the 
course of the study, the management guidelines are not exhaustive and do not represent a full 
spectrum of care or treatment options. 
 
In general, an adverse event related to study treatment that results in a dose delay should be 
present on the day of intended study treatment (i.e. a delayed toxicity that develops mid-cycle, but 
which is no longer present or has resolved to an acceptable grade on the day of intended dosing, 
generally does not require a delay in treatment – unless, for example, the occasion involves 
retrospective detection of a prior event of sufficient grade to, regardless of duration, require delay 
or discontinuation). 
 
Each adverse event will be graded according to the NCI’s Common Terminology Criteria for 
Adverse Events (NCI CTCAE), Version 5.0, dated November 27, 2017; the therapy modifications 
described in this section are applied according to this severity grading. 
 
In the event of multiple concurrent adverse events, treatment modification should be based on 
toxicity with the most severe grade.  Each treatment delay must be documented, including the 
respective reason. 
 
For purpose of any necessary definition with respect to adverse event management, “baseline 
value” is defined as the documented value in place most immediately prior to patient’s first receipt 
of nivolumab, relatlimab or ipilimumab on Cycle 1, Day 1. 
 
Nivolumab and/or relatlimab, and nivolumab and/or ipilimumab, may be delayed for any adverse 
event, laboratory abnormality, or intercurrent illness which, in the judgment of the study physician, 
warrants delaying the dose for purpose of increased patient safety. 
 
In the event of an adverse event deemed by the study physician as not related or unlikely related 
to protocol-indicated treatment, the study physician may nevertheless optionally choose to 
precautionarily interrupt nivolumab/relatlimab (either or both drugs), or nivolumab/ipilimumab 
(either or both drugs), for up to 42 days from the last respective dose. 
 
In the event of treatment interruption, the study records should reflect treatment was withheld; 
other visit assessments and procedures however, including re-scanning for monitoring disease 
progression, must continue per protocol according to the timeline in place prior to the dose 
interruption. 
 
11.1.  Dose Modifications 
 
There will be no dose reductions for nivolumab, ipilimumab, or relatlimab.  Adverse events 
requiring dose modification will be managed by dose delay.

11.2.  Criteria for Dose Delays 
 
Dose delay criteria apply for all adverse events deemed by the investigator to be possibly, 
probably or definitely drug-related, regardless of whether or not the event is attributed to 
nivolumab, ipilimumab, relatlimab, or combinations.  
 
All study drugs (i.e. nivolumab, ipilimumab and relatlimab) must be delayed until treatment can 
resume (see Section 11.3).  
 
Treatment delays up to 6 weeks from the last dose are allowable. 
 
ARM A:  Nivolumab and relatlimab should be delayed for the following: 
• 
Select drug-related AEs and drug-related laboratory abnormalities: 
 
 ≥ Grade 3 skin. 
 
  ≥ Grade 1 pneumonitis. 
 
 ≥ Single grade increase shift in abnormality in AST, ALT, and total bilirubin. 
 
 ≥ Grade 2 creatinine. 
 
 ≥ Grade 2 diarrhea or colitis. 
 
 ≥ Grade 2 neurological AE. 
 
 Grade 4 amylase and/or lipase abnormalities regardless of symptoms or clinical 
manifestations. 
 
• 
Myocarditis (any grade). 
 
• 
All troponin elevations require a dose delay to allow for prompt cardiac evaluation.  
Following this evaluation, determination of further treatment will be based on the discretion 
of the investigator. 
 
• 
Any AE, laboratory abnormality, or concurrent illness that, in the judgment of the 
investigator, warrants delaying the dose of study drug. 
ARM B:  Nivolumab and ipilimumab should be delayed for the following: 
• 
Any Grade ≥ 2 non-skin, drug-related adverse event, with the following exceptions: 
 
 
Grade 2 drug-related fatigue or laboratory abnormalities do not require a 
treatment delay. 
 
• 
Any Grade 3 skin, drug-related adverse event. 
 
• 
Any Grade 3 drug-related laboratory abnormality, with the following exceptions for 
asymptomatic amylase or lipase, AST, ALT, or total bilirubin: 
 
 
Grade 3 amylase or lipase abnormalities that are not associated with symptoms 
or clinical manifestations of pancreatitis do not require a dose delay.  It is 
recommended to consult with the sponsor-investigator for Grade 3 amylase or 
lipase abnormalities. 
 
 
If a patient has a baseline AST, ALT, or total bilirubin that is within normal limits, 
delay dosing for drug-related Grade ≥ 2 toxicity. 
 
 
If a patient has baseline AST, ALT, or total bilirubin within the Grade 1 toxicity 
range, delay dosing for drug-related Grade ≥ 3 toxicity.

11.3.  Criteria to Resume Treatment 
 
When a patient’s treatment with study drug is interrupted due to adverse event, the patient’s 
treatment may be resumed when the drug-related AE(s) resolve to Grade ≤1 or baseline value, 
with the following exceptions: 
• 
Patients may resume treatment in the presence of Grade 2 fatigue. 
 
• 
Patients who have not experienced a Grade 3 drug-related skin AE may resume treatment 
in the presence of Grade 2 skin toxicity. 
 
• 
Patients with baseline Grade 1 AST/ALT or total bilirubin who require dose delays for 
reasons other than a 2-grade shift in AST/ALT or total bilirubin may resume treatment in 
the presence of Grade 2 AST/ALT OR total bilirubin. 
 
• 
Patients with combined Grade 2 AST/ALT AND total bilirubin values meeting 
discontinuation parameters (Section 11.4) should have treatment permanently 
discontinued. 
 
• 
Drug-related pulmonary toxicity, diarrhea, or colitis, must have resolved to baseline before 
treatment is resumed.  Patients with persistent Grade 1 pneumonitis after completion of a 
steroid taper over at least 1 month are eligible for retreatment at the discretion of the 
investigator. 
 
• 
Drug-related endocrinopathies adequately controlled with only physiologic hormone 
replacement may resume treatment. 
 
• 
Patients in Arm A may resume treatment with relatlimab when troponin levels return to 
normal. 
 
If the criteria to resume treatment are met, the subject should restart treatment at the next 
scheduled time point per protocol. However, if the treatment is delayed past the scheduled 
time point per protocol, the scheduled study treatment administration will be delayed, but not 
skipped, until dosing resumes.  In particular, this is to ensure that subjects in Arm B will 
receive 4 administrations of combined nivolumab and ipilimumab treatment if toxicity allows. 
 
If dose delay is necessary for subjects in Arm B during Weeks 1-12 (i.e. Cycles 1 thru 4), then 
both nivolumab and ipilimumab must be delayed until treatment can resume. However, if a 
nivolumab-related infusion reaction prevents subsequent infusion of ipilimumab on the same day, 
the dose of ipilimumab should be replaced as soon as possible. In such instances, at least 19 days 
must elapse between the replacement dose of ipilimumab and the administration of the next dose 
of nivolumab combined with ipilimumab. 
 
If treatment is delayed or interrupted for > 6 weeks, the subject must be permanently discontinued 
from study therapy, except as otherwise specified (e.g. in Section 11.4).

11.4.  Criteria to Permanently Discontinue Treatment 
 
Treatment with nivolumab, ipilimumab, and/or relatlimab (BMS-986016) should be permanently 
discontinued for the following: 
• 
Any Grade 2 drug-related uveitis or eye pain or blurred vision that does not respond to 
topical therapy and does not improve to Grade 1 severity within the re-treatment period 
OR requires systemic treatment. 
 
• 
Any Grade 3 non-skin, drug-related adverse event lasting > 7 days, with the following 
exceptions for drug-related laboratory abnormalities, endocrinopathies, uveitis, 
pneumonitis, bronchospasm, diarrhea, colitis, neurologic toxicity, hypersensitivity 
reactions, and infusion reactions: 
 
 Grade 3 drug-related uveitis, pneumonitis, bronchospasm, diarrhea, colitis, 
neurologic toxicity, hypersensitivity reaction, or infusion reaction of any duration 
requires discontinuation. 
 
 For Grade 3 endocrinopathy adverse events such as adrenal insufficiency, ACTH 
deficiency, hyper- or hypothyroidosis, or glucose intolerance, which resolve or 
are adequately controlled with physiologic hormone replacement (steroids, 
thyroid hormones) or glucose controlling agents, respectively, do not require 
treatment discontinuation. 
 
 Grade 3 drug-related laboratory abnormalities do not require treatment 
discontinuation except: 
 
 Grade 3 drug-related thrombocytopenia > 7 days or associated with 
bleeding requires discontinuation. 
 
 Any drug-related liver function test (LFT) abnormality that meets the 
following criteria requires discontinuation: 
 
o 
AST or ALT > 5 x ULN. 
o 
Total bilirubin > 3 x ULN. 
o 
Concurrent AST or ALT > 3 x ULN and total bilirubin > 2 x ULN. 
 
• 
Any Grade 3 myocarditis. 
 
• 
Any Grade 4 drug-related adverse event or laboratory abnormality, except for the 
following events which do not require discontinuation: 
 
 
Grade 4 amylase or lipase abnormalities that are not associated with symptoms 
or clinical manifestations of pancreatitis.  It is recommended to consult with the 
sponsor-investigator for Grade 4 amylase or lipase abnormalities. 
 
 
Isolated Grade 4 electrolyte imbalances/abnormalities that are not associated 
with clinical sequelae and are corrected with supplementation/appropriate 
management within 72 hours of their onset. 
 
• 
Any dosing interruption lasting > 6 weeks from the last dose with the following 
exceptions: 
 
 Dosing interruptions to allow for prolonged steroid tapers to manage drug-related 
adverse events are allowed.  Prior to re-initiating treatment in a subject with a 
dosing interruption lasting > 6 weeks from the last dose, the sponsor-investigator 
must be consulted in writing.  Tumor imaging assessments should continue as 
per protocol even if dosing is interrupted.

 Dosing interruptions > 6 weeks from the last dose that occur for non-drug-related 
reasons may be allowed if approved by the sponsor-investigator.  Prior to re-
initiating treatment in a subject with a dosing interruption lasting > 6 weeks from 
the last dose, the sponsor-investigator must be consulted.  Tumor imaging 
assessments should continue as per protocol even if dosing is interrupted. 
 
Any adverse event, laboratory abnormality, or intercurrent illness which, in the judgment of the 
Investigator, presents a substantial clinical risk to the patient with continued study drug dosing 
should discontinue the study drugs. 
 
The consideration to re-initiate study therapy in selected cases at any time point after 
discontinuation could be made on a case-by-case basis after considering the overall benefit/risk 
profile and in consultation between the investigator and the sponsor-investigator.  The selected 
patients will need to meet eligibility criteria.  The original dose and schedule and protocol rules 
would apply accordingly (Section 11.4). 
In this trial, combinatorial treatment with relatlimab and nivolumab (Arm A) or ipilimumab and 
nivolumab (Arm B) shall be considered separable (see also Section 9.9):   
• 
Arm A:  The assessment for discontinuation of drug should be made separately 
considering each drug component in the nivolumab + relatlimab combination (Arm A).  If 
discontinuation criteria are attributed to only one drug used in this combination, once the 
patient meets criteria to resume therapy, the subject may continue dosing with nivolumab 
(if nivolumab was not attributed to criteria for discontinuation) and/or with relatlimab (if 
relatlimab was not attributed to criteria for discontinuation). 
 
• 
Arm B:  The assessment for discontinuation of drug should be made separately 
considering each drug component in the nivolumab + ipilimumab combination (Arm B).  If 
discontinuation criteria are attributed to only one drug used in this combination, once the 
patient meets criteria to resume therapy, the subject may continue dosing with nivolumab 
(if nivolumab was not attributed to criteria for discontinuation) and/or with ipilimumab (if 
ipilimumab was not attributed to criteria for discontinuation). 
If a patient meets criteria for discontinuation and the investigator is unable to determine whether 
the event is related to both or one study drug, the patient should discontinue all study drugs and 
be taken off the treatment phase of the study. 
 
11.5.  Treatment of Nivolumab, Ipilimumab, and Relatlimab Related Infusion 
Reactions 
 
If infusion reaction or hypersensitivity were to occur, manifestation might include fever, chills, 
rigors, headache, rash, pruritus, arthralgias, hypo- or hypertension, bronchospasm, or other 
symptoms. 
 
According to the relatlimab investigator brochure15, the all-combination group of study CA224020 
includes 1166 subjects treated with relatlimab and nivolumab.  The all-combination group includes 
Parts B+C+D.  In combination therapy (Parts B, C, and D), 22 Grade 1 and 37 Grade 2 infusion-
related reactions were reported.  There were no Grade 3 or higher infusion reactions reported.  
The overall frequency (5.1%) observed in Study CA224020 is similar to the frequency observed for 
nivolumab monotherapy:  In patients receiving nivolumab as a 60-minute intravenous infusion, 
infusion-related reactions occurred in 6.4% (127/1994) of patients; and in a trial assessing the 
pharmacokinetics and safety of a more rapid infusion, in which patients received nivolumab as a 
60-minute intravenous infusion or a 30-minute intravenous infusion, infusion-related reactions 
occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively.  Refer to Section 5.9 of the

nivolumab label14 for further details.  All events were manageable per updated protocol guidelines, 
and only 2 subjects required treatment discontinuation, in each case due to recurrent Grade 2 
infusion related reactions.15 
 
Data regarding serious adverse reactions (i.e. “Serious Adverse Reactions for relatlimab 
monotherapy and relatlimab + nivolumab Considered Expected for Safety Reporting Purposes 
(N=1401)” in Table 1-2 of Appendix 1 of the relatlimab investigator brochure lists (serious) infusion 
related reaction as an uncommon event [i.e. n=4 (0.29%)] with no occurrence of life-threatening or 
fatal serious adverse reactions.15 
 
All Grade 3 or 4 infusion reactions should be reported within 24 hours to the Coordinating Center 
and reported as an SAE if criteria are met (Section 13).  Infusion reactions should be graded 
according to NCI CTCAE (version 5.0) guidelines. 
 
Treatment recommendations are provided below and may be modified based on local treatment 
standards and guidelines as appropriate: 
 
For Grade 1 symptoms (Mild reaction; infusion interruption not indicated; intervention not 
indicated): 
 
• 
Remain at bedside and monitor subject until recovery from symptoms. 
 
• 
The following prophylactic premedications are recommended for future infusions: 
diphenhydramine 50 mg (or equivalent) and/or paracetamol 325 to 1000 mg 
(acetaminophen) at least 30 minutes before additional nivolumab administrations. 
For Grade 2 symptoms (Moderate reaction requires therapy or infusion interruption but responds 
promptly to symptomatic treatment [eg, antihistamines, non-steroidal anti-inflammatory drugs, 
narcotics, corticosteroids, bronchodilators, IV fluids]; prophylactic medications indicated for ≤ 24 
hours): 
 
• 
Stop the study drug infusion, begin an IV infusion of normal saline, and treat the subject 
with diphenhydramine 50 mg IV (or equivalent) and/or paracetamol 325 to 1000 mg 
(acetaminophen); remain at bedside and monitor subject until resolution of symptoms. 
Corticosteroid or bronchodilator therapy may also be administered as appropriate. 
 
• 
If the infusion is interrupted, then restart the infusion at 50% of the original infusion rate 
when symptoms resolve; if no further complications ensue after 30 minutes, the rate may 
be increased to 100% of the original infusion rate.  Monitor subject closely.  If symptoms 
recur then no further study drug will be administered at that visit.  Administer 
diphenhydramine 50 mg IV, and remain at bedside and monitor the subject until resolution 
of symptoms.  The amount of study drug infused must be recorded on the electronic case 
report form (eCRF). 
 
• 
The following prophylactic premedications are recommended for future infusions: 
diphenhydramine 50 mg (or equivalent) and/or paracetamol 325 to 1000 mg 
(acetaminophen) should be administered at least 30 minutes before additional study drug 
administrations.  If necessary, corticosteroids (recommended dose: up to 25 mg of IV 
hydrocortisone or equivalent) may be used. 
For Grade 3 or Grade 4 symptoms (Severe reaction, Grade 3: prolonged [ie, not rapidly 
responsive to symptomatic medication and/or brief interruption of infusion]; recurrence of 
symptoms following initial improvement; hospitalization indicated for other clinical sequelae 
[eg, renal impairment, pulmonary infiltrates]). Grade 4: (life-threatening; pressor or ventilator 
support indicated): 
 
• 
Immediately discontinue infusion of study drug.

Begin an IV infusion of normal saline, and treat the subject as follows.  Recommend 
bronchodilators, epinephrine 0.2 to 1 mg of a 1:1,000 solution for subcutaneous 
administration or 0.1 to 0.25 mg of a 1:10,000 solution injected slowly for IV 
administration, and/or diphenhydramine 50 mg IV with methylprednisolone 100 mg IV (or 
equivalent), as needed. 
 
• 
Subject should be monitored until the investigator is comfortable that the symptoms will 
not recur. 
 
• 
Study drug will be permanently discontinued. 
 
• 
Investigators should follow their institutional guidelines for the treatment of anaphylaxis. 
Remain at bedside and monitor subject until recovery from symptoms. 
 
• 
In the case of late-occurring hypersensitivity symptoms (eg, appearance of a localized or 
generalized pruritus within 1 week after treatment), symptomatic treatment may be given 
(eg, oral antihistamine, or corticosteroids). 
 
11.6.  Management Algorithms for Immuno-Oncology Agents 
 
Immuno-oncology (I-O) agents are associated with adverse events (AEs) which in severity and 
duration can differ from AEs caused by other therapeutic classes.  In this protocol, nivolumab, 
ipilimumab, and relatlimab are considered immuno-oncology agents.  Early recognition and 
management of AEs associated with immuno-oncology agents may mitigate severe toxicity.  
 
Management Algorithms have been developed to assist investigators in assessing and managing 
the following groups of AEs:  
 
• 
Gastrointestinal  
• 
Renal  
• 
Pulmonary  
• 
Hepatic  
• 
Endocrinopathy  
• 
Skin  
• 
Neurological 
• 
Myocarditis. 
 
For the above events deemed by the investigator as possibly, probably or definitely related to 
nivolumab, ipilimumab, and/or relatlimab, Management Algorithms are found in Appendix 6.   
 
While safety management algorithms for similar adverse events may be presented elsewhere (e.g. 
ipilimumab investigator brochure), the recommendations for the combinatorial treatments outlined 
in this study protocol are to follow the nivolumab-based algorithms for immuno-oncology agents, in 
order to standardize safety management in this protocol.  For individual cases, adverse event 
treatment management algorithms included in the nivolumab IB or ipilimumab IB might be 
considered. 
 
The guidance provided in these algorithms should not replace the investigator’s medical judgment 
but should complement it.

12.  DRUG FORMULATION, SUPPLY AND STORAGE 
 
12.1.  Description of Nivolumab 
Nivolumab (OPDIVO) is a programmed death receptor-1 (PD-1) blocking antibody that is currently 
approved for a variety of indications including melanoma with lymph node involvement or 
metastatic disease after complete resection, in the adjuvant setting; unresectable or metastatic 
melanoma, as a single agent or in combination with ipilimumab; metastatic non-small cell lung 
cancer and progression on or after platinum-based chemotherapy; metastatic small cell lung 
cancer with progression after platinum-based chemotherapy and at least one other line of therapy; 
advanced renal cell carcinoma after prior anti-angiogenic therapy; intermediate or poor risk, 
previously untreated advanced renal cell carcinoma, in combination with ipilimumab; classical 
Hodgkin lymphoma that has relapsed or progressed after autologous hematopoietic stem cell 
transplantation (HSCT) and brentuximab vedotin, or 3 or more lines of systemic therapy that 
includes HSCT; recurrent or metastatic squamous cell carcinoma of the head and neck with 
progression on or after platinum-based therapy; locally advanced or metastatic urothelial 
carcinoma with progression (during or following platinum-containing chemotherapy, or within 12 
months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy); adult and 
pediatric metastatic colorectal cancer (microsatellite instability-high or mismatch repair deficient) 
after progression on a fluoropyrimidine, oxaliplatin, and irinotecan, as a single agent or in 
combination with ipilimumab; and hepatocellular carcinoma after sorafenib treatment.14  
 
12.2.  Packaging of Nivolumab 
The study will supply nivolumab to the site. 
 
Nivolumab is typically available as nivolumab injection:  40 mg/4 mL (10 mg/mL), 100 mg/10 mL 
(10 mg/mL), and 240 mg/24mL (10 mg/mL) clear to opalescent, colorless to pale-yellow solution in 
a single-dose vial. 
 
Nivolumab drug product should be visually inspected for particulate matter and discoloration prior 
to administration. Discard the vial if the solution is cloudy, discolored, or contains extraneous 
particulate matter other than a few translucent-to-white, proteinaceous particles.  Do not shake the 
vial.14 
 
12.3.  Handling and Storage of Nivolumab 
Nivolumab product does not contain a preservative.  Nivolumab will be prepared according to the 
product label.  After preparation, the diluted nivolumab solution should be stored either14: 
 
• 
At room temperature for no more than 8 hours from the time of preparation to end of the 
infusion.  Discard diluted solution if not used within 8 hours from the time of preparation; or 
 
• 
Under refrigeration at 2°C to 8°C (36°F to 46°F) for no more than 24 hours from the time 
of preparation to end of infusion.  Discard diluted solution if not used within 24 hours from 
the time of preparation. 
 
Do not freeze.

12.4.  Description of Ipilimumab 
Ipilimumab (YERVOY) is a recombinant human monoclonal antibody that binds to the cytotoxic T-
lymphocyte-associated-antigen 4 (CTLA-4), a negative regulator of T-cell activity.  An IgG1 kappa 
immunoglobulin, ipilimumab is approved for treatment of unresectable or metastatic melanoma; 
adjuvant treatment of cutaneous melanoma with involvement of regional lymph nodes after 
resection; intermediate or poor risk, previously untreated advanced renal cell carcinoma, in 
combination with nivolumab; and under accelerated approval for microsatellite instability-high 
(MSI-H) or mismatch repair deficient (dMMR) metastatic colorectal cancer that has progressed 
following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan, in combination with 
nivolumab.16 
 
12.5.  Packaging of Ipilimumab 
The study will provide ipilimumab to the site. 
 
Ipilimumab is a sterile, preservative-free, clear to slightly opalescent, colorless to pale yellow 
solution for intravenous infusion, which may contain a small amount of visible translucent-to-white, 
amorphous ipilimumab particulates.  It is typically supplied in single-use vials of 50 mg/10 mL (5 
mg/mL) and 200 mg/40 mL (5 mg/mL).  Each milliliter contains 5 mg of ipilimumab and the 
following inactive ingredients: diethylene triamine pentaacetic acid (DTPA) (0.04 mg), mannitol (10 
mg), polysorbate 80 (vegetable origin) (0.1 mg), sodium chloride (5.85 mg), tris hydrochloride 
(3.15 mg), and water for injection, USP at a pH of 7.16 
 
12.6.  Handling and Storage of Ipilimumab 
Store ipilimumab under refrigeration at 2°C to 8°C (36°F to 46°F).  Protect ipilimumab from light 
by storing in the original carton until time of use.  Do not freeze or shake.16 
 
12.7.  Description of Relatlimab (BMS-986016) 
Relatlimab (also known as BMS-986016) is a fully human antibody against the lymphocyte 
activation gene 3 (LAG-3) product.  LAG-3 (CD223) is a negative regulatory T-cell receptor 
implicated in the control of T-cell function in conventional and regulatory T cells.  An 
immunoglobulin G4 (IgG4) isotype antibody including a stabilizing hinge mutation (S228P), 
relatlimab binds to the LAG-3 receptor on T cells with high affinity, thus blocking LAG-3 
interactions with its ligand, the major histocompatibility complex (MHC) Class II, the peptide 
antigen presentation molecule recognized by CD4+ T-cells.  When administered alone or in 
combination with other therapeutic immuno-oncology monoclonal antibodies, it is hoped that 
relatlimab may enhance the anti-tumor immune response via blocking the downregulatory pathway 
otherwise involved in maintaining T-cell quiescence.15 
 
12.8.  Packaging of Relatlimab 
The study will supply to each site relatlimab injection drug product for intravenous (IV) 
administration. 
 
Two formulations of relatlimab injection for IV administration are currently available as 100 mg/vial 
(10 mg/mL) in 10-cc vials.  The same excipients are used for both formulations, except for one 
formulation with and the other without pentetic acid.  A third relatlimab formulation (with pentetic 
acid) for IV administration is also currently available as 80mg/vial. 
 
All three relatlimab formulations for IV administration are a colorless to pale yellow liquid, clear to 

Vanderbilt University Medical Center 
Version 6.0 
Clinical Trial Protocol – VICCMEL18114 
30 March 2020

63 of 100 
 
slightly opalescent, and light (few) particles (consistent in appearance to protein particulates) may 
be present.  All three formulations are pH 5.0 to 6.0, with a container closure system of a 10cc 
Type1 flint glass vial stoppered with fluoropolymer film-laminate rubber stoppers and sealed with 
aluminum seals.  The components of the 3 relatlimab formulations for IV administration are15: 
 
• 
Relatlimab injection (100mg/vial) without pentetic acid:  Relatlimab, histidine, histidine 
hydrochloride monohydrate, sucrose, polysorbate 80, water for injection. 
 
• 
Relatlimab injection (100mg/vial or 80mg/vial) with pentetic acid:  Relatlimab, histidine, 
histidine hydrochloride monohydrate, sucrose, pentetic acid, polysorbate 80, water for 
injection. 
 
Note: In addition to the three relatlimab formulations for IV administration mentioned above, two  
additional relatlimab products are also available for subcutaneous administration (e.g. see Table 
3.2.1-1 of the investigator brochure15).  However, under this clinical study protocol as presently 
configured, there are no current plans for subcutaneous administration of relatlimab (which will 
continue to be administered as an intravenous infusion consistent with above protocol Section 9). 
 
12.9.  Handling and Storage of Relatlimab 
Relatlimab drug product for intravenous administration should be stored at 2°C to 8°C (36°F to 
46°F) with protection from light. Do not freeze the drug product. 
 
The intravenous administration of relatlimab infusion must be completed within 24 hours of 
preparation.  If not used immediately, the infusion solution may be stored in a refrigerator at 2°C to 
8°C (36°F to 46°F) for up to 24 hours and a maximum of 4 hours of the total 24 hours can be at 
room temperature (15°C to 25°C; 59°F to 77°F) and exposed to room light.  The maximum 4-hour 
period under room temperature and room light conditions includes the product administration 
period.15 
 
12.10.  Relatlimab Drug Accountability and Compliance Check 
The investigator is responsible for ensuring accountability for relatlimab, including maintenance of 
drug accountability records. 
 
Drug accountability records will appropriately document a full inventory relatlimab including: 
 
• 
Confirmation of relatlimab delivery to the trial site 
 
• 
A record of each dose of relatlimab dispensed 
 
• 
The return of relatlimab provided by the study to the sponsor-investigator or designee, or 
documentation of destruction at the site (if drug destruction at the site is authorized in 
advance in writing by the sponsor-investigator or designee). 
 
Records will specify relevant dates, quantities, batch numbers, use-by dates and patient numbers, 
as applicable. 
 
The investigator, or designee, should maintain records that adequately document: 
 
• 
That patients were provided the doses specified by the clinical trial protocol, and 
 
• 
That all relatlimab provided by the study was fully reconciled.

13.  SAFETY REPORTING OF ADVERSE EVENTS 
 
13.1.  General 
Adverse events will be graded according to the NCI’s Common Terminology Criteria for Adverse 
Events (NCI CTCAE), Version 5.0, dated November 27, 2017, currently locatable via the following 
URL: 
<https://ctep.cancer.gov/protocoldevelopment/electronic_applications/docs/CTCAE_v5_Quick_Ref
erence_8.5x11.pdf>. 
 
If events are not listed in the CTCAE, severity may be designated as mild, moderate, severe, life-
threatening, or fatal which respectively correspond to Grades 1, 2, 3, 4, and 5 on the NCI CTCAE, 
with the following definitions: 
 
• 
Mild:  Asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated; 
 
• 
Moderate:  Minimal, local or noninvasive intervention indicated; limiting age-
appropriate instrumental activities of daily living (ADL) such as preparing meals, 
shopping for groceries or clothes, using the telephone, managing money, etc; 
 
• 
Severe:  Medically significant but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limiting self care ADL such as 
bathing, dressing and undressing, feeding self, using the toilet, taking medications; 
 
• 
Life-threatening:  Urgent intervention indicated to prevent risk of death present at the 
time of the event; 
 
• 
Fatal:  An event that results in the death of the patient. 
 
Information on adverse events, whether serious or not, whether reported by the participant, 
directly observed, or detected by physical examination, laboratory test or other means, will be 
collected, recorded, followed and reported as described in the following sections.  
 
Non-serious adverse events experienced by a participant will be collected and reported from 
initiation of nivolumab/relatlimab/ipilimumab, throughout the study; and until 100 days after 
patient’s final study-indicated treatment with nivolumab, relatlimab or ipilimumab (whichever 
occurs last) or until initiation of another anticancer therapy – whichever occurs first.  Participants 
who experience an ongoing adverse event possibly, probably or definitely related to a study 
procedure and/or study medication beyond 100 days will continue to be contacted by a member of 
the study team until the event is resolved, stabilized, or determined to be irreversible or not 
clinically significant by the investigator. 
 
After informed consent but prior to initiation of nivolumab/relatlimab or nivolumab/ipilimumab, non-
serious adverse events should be reported only if possibly, probably or definitely attributed by the 
patient’s study physician to a protocol-mandated procedure or intervention. 
 
After informed consent, any Serious Adverse Event (SAE) that occurs during the clinical 
study or within 100 days after a patient’s last dose of protocol-indicated nivolumab, 
relatlimab or ipilimumab, regardless of causality to study drug, must be reported to the 
Coordinating Center in an expedited fashion as directed below (Reporting Procedures). 
 
During the 30-day follow-up period, new onset, non-serious adverse events should only be 
recorded if, in the opinion of the investigator, there is a reasonable possibility the event is 
attributable to the investigational product.  Non-serious adverse events related to the next phase 
of the patient’s treatment should NOT be recorded.  All serious adverse events occurring within 

Vanderbilt University Medical Center

65 of 100 
 
the 30-day follow-up period must be reported, regardless of suspected causality.   
 
Participants should be instructed to report any serious post-study event(s) that might reasonably 
be related to participation in this study.  The investigator should notify the IRB and the 
Coordinating Center of any unanticipated death or adverse event occurring after a participant has 
discontinued or terminated study participation that may reasonably be related to the study. 
 
13.2.  Risks Associated with Nivolumab 
The most common adverse reactions (≥20%) in patients were: 
 
• 
Nivolumab as a single agent:  fatigue, rash, musculoskeletal pain, pruritus, diarrhea, 
nausea, asthenia, cough, dyspnea, constipation, decreased appetite, back pain, arthralgia, 
upper respiratory tract infection, pyrexia, headache, abdominal pain, and vomiting. 
 
• 
Nivolumab in combination with ipilimumab:  fatigue, rash, diarrhea, nausea, pyrexia, 
vomiting, dyspnea, musculoskeletal pain, pruritus, abdominal pain, cough, arthralgia, 
decreased appetite, and upper respiratory infection. 
 
A more detailed safety profile of nivolumab is provided in the investigator’s brochure17; and in the 
product label14, currently locatable online via the following: 
 
Nivolumab (OPDIVO): 
< https://packageinserts.bms.com/pi/pi_opdivo.pdf >. 
 
13.3.  Risks Associated with Relatlimab (BMS-986016) 
• 
The current industry-sponsored clinical program is evaluating advanced solid tumors 
(advanced melanoma after previous progression on prior anti-PD1 therapy) in Study 
CA224020; relapsed-refractory hematological malignancies (Hodgkin lymphoma) in Study 
CA224022; advanced solid tumors (special focus in a Japanese population) in Study 
CA224034; and, in Study CA224048, advanced solid tumors including melanoma, non-
small cell lung cancer (NSCLC), squamous cell cancer of head and neck (SCCHN), renal 
cell cancer (RCC), and gastric cancer (GC/GEJ).  
 
As of the respective clinical data cutoff dates (CA224020: 03-Jun-2019; CA224022: 26-
Jun-2019; CA224034 and CA224048: 15-May-2019): 1348 subjects in total (1191 in study 
CA224020, 104 in CA224022, 29 in CA224034 and 24 in CA224048) have been treated 
with relatlimab in 4 ongoing Phase 1 and Phase 2a Bristol-Myers Squibb Company (BMS)-
sponsored studies assessing the PK, efficacy, and safety of relatlimab alone or in 
combination with nivolumab or ipilimumab or BMS 986205 (IDO-1 inhibitor) in subjects 
with advanced solid tumors and hematological malignancies.15 
 
• 
Across the 4 studies (CA224020, CA224022, CA224034 and CA224048), relatlimab 
monotherapy has been administered to 66 subjects across multiple doses: 20 mg (8 
subjects), 80 mg (13 subjects), 240 mg (27 subjects) and 800 mg (18 subjects) relatlimab, 
flat dose, Q2W. 
 
The safety profile of relatlimab monotherapy appears manageable with no maximum 
tolerated dose (MTD) reached.  The maximum administered dose (MAD) was 800 mg 
Q2W.  There were 4 drug-related SAEs in monotherapy: Grade 3 pneumonitis, Grade 2 
pneumonitis, and Grade 3 allergic reaction in monotherapy in Study CA224020 at a dose 
of 800 mg relatlimab Q2W; and a Grade 3 aseptic meningitis in monotherapy in Study 
CA224022 at a dose of 800 mg relatlimab Q2W. 
 
There was no apparent relationship in the incidence, severity, or causality of AEs to

relatlimab at these dose levels.  All AEs were reversible or manageable (in the setting of 
immune-mediated endocrine events) by withholding drug administration and following 
treatment algorithms specified in the protocols where applicable. 
 
There were 5 Grade 1 to Grade 2 infusion-related reactions with relatlimab monotherapy 
(1 in Study CA224020 and 4 in Study CA224022), which were manageable and reversible 
with recommended treatment guidelines in the protocol.  A total of 27 subjects died due to 
malignant neoplasm progression following relatlimab monotherapy (19 in Study 
CA224020, 7 in Study CA224022, and 1 in Study CA224034).15 
 
• 
The all-combination group of study CA224020 includes 1166 subjects treated with 
relatlimab and nivolumab.  Drug-related AEs were reported in 739 (63.4%) subjects, with 
the most commonly reported (≥ 5% of subjects) being fatigue (14.5%), pruritus (9.1%), 
diarrhea (8.4%), asthenia (6.5%), rash (6.4%), nausea (6.2%), arthralgia (6.2%), 
hypothyroidism (6.3%) and increased lipase (5.9%). 
 
Grade 3 drug-related AEs were reported in 132 (11.3%) subjects, Grade 4 in 30 (2.6%) 
subjects, and Grade 5 in 1 (0.1%) subject.  Grade 3 to 4 drug-related AEs were reported in 
at least 162 (13.9%) subjects and included increased lipase (3.2%), colitis, increased 
amylase (1.3% each), increased ALT (1.0%), pneumonitis (0.8%), diarrhea (0.9%), 
increased AST (0.5%), autoimmune hepatitis (0.4%), myocarditis, type 1 diabetes mellitus, 
gastritis, maculo-papular rash, hypophysitis, hepatitis, anaemia, asthenia, fatigue and 
mucosal inflammation (0.3% each). 
 
Drug-related SAEs were reported in 119 of the 1166 (10.2%) subjects treated with 
relatlimab and nivolumab in Parts B, C, and D.  Grade 3 to 4 drug-related SAEs occurring 
in 3 or more subjects included pneumonitis, colitis, myocarditis, aspartate 
aminotransferase increase, autoimmune hepatitis, immune-mediated hepatitis, diarrhea, 
gastritis, hypophysitis, increased lipase, and type 1 diabetes mellitus.  All SAEs, (all at a 
dose level of 80 mg relatlimab/240 mg nivolumab Q2W), were reversible and manageable 
by withholding study drug administration providing standard medical care, and/or following 
immune-related AE algorithms. 
 
In combination therapy (Parts B, C, and D), 22 Grade 1 and 37 Grade 2 infusion-related 
reactions were reported.  There were no Grade 3 or higher infusion reactions reported.  
The overall frequency (5.1%) observed in Study CA224020 is similar to the frequency 
observed for nivolumab monotherapy.  In patients receiving OPDIVO as a 60-minute 
intravenous infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. 
Refer to Section 5.9 of (OPDIVO USPI) for further details.14  All events were manageable 
per updated protocol guidelines, and only 2 subjects required treatment discontinuation, in 
each case due to recurrent Grade 2 infusion related reactions.15 
 
• 
A more detailed safety profile of relatlimab is provided in the investigator’s brochure.15 
 
13.4.  Risks Associated with Ipilimumab 
• 
The most common adverse reactions (≥5%) with ipilimumab as a single agent are fatigue, 
diarrhea, pruritus, rash, and colitis.  Additional common adverse reactions at the 10 mg/kg 
dose (≥5%) include nausea, vomiting, headache, weight loss, pyrexia, decreased appetite, 
and insomnia. 
 
• 
The most common adverse reactions (≥20%) with ipilimumab in combination with 
nivolumab are fatigue, rash, diarrhea, musculoskeletal pain, pruritus, nausea, cough, 
pyrexia, arthralgia, decreased appetite, abdominal pain, vomiting, and dyspnea. 
 
• 
A more detailed safety profile of ipilimumab is provided in the product label16, currently

13.5.  Potential Drug Induced Liver Injury (DILI) 
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.  Potential drug induced liver injury is defined as: 
 
1) ALT or AST elevation > 3 times upper limit of normal (ULN)  
 
AND 
 
2) Total bilirubin > 2 times ULN, without initial findings of cholestasis (elevated serum alkaline 
phosphatase) 
 
AND 
 
3) No other immediately apparent possible causes of AST/ALT 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. 
 
13.6.  Pregnancy 
If, following initiation of the investigational product, it is subsequently discovered that a study 
participant is pregnant or may have been pregnant at the time of investigational product exposure, 
including during at least 5 half-lives after product administration, the investigational product will be 
permanently discontinued in an appropriate manner (e.g. dose tapering if necessary for participant 
safety).  
 
Via SAE reporting procedures (Section 13.9), the investigator must immediately report this event 
using either the MedWatch or appropriate Pregnancy Surveillance Form (provided upon request 
from BMS), or approved site SAE form.  
 
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, offspring information must be reported on the MedWatch, 
Pregnancy Surveillance Form, or approved site SAE form. 
 
Any pregnancy that occurs in a female partner of a male study participant (until such time that any 
protocol-required contraception is no longer required by protocol) should be reported using the 
MedWatch, Pregnancy Surveillance Form, or approved site SAE form via SAE reporting 
procedures (Section 13.9).  In order for the sponsor-investigator or designee to collect any 
pregnancy surveillance information from the female partner, the female partner must sign an 
informed consent form for disclosure of this information.  
 
13.7.  Overdose 
An overdose is defined as the accidental or intentional administration of any dose of a product that 
is considered both excessive and medically important.  All occurrences of overdose must be 
reported as an SAE.

13.8.  Definitions 
13.8.1 Adverse Event (AE) 
An adverse event is any undesirable sign, symptom or medical condition or experience that 
develops or worsens in severity after starting the first dose of study treatment or any procedure 
specified in the protocol, even if the event is not considered to be related to the study.   
 
Abnormal laboratory values or diagnostic test results constitute adverse events only if they induce 
clinical signs or symptoms or require treatment or further diagnostic tests. 
 
13.8.2 Serious Adverse Event (SAE) 
A serious adverse event is an undesirable sign, symptom or medical condition which: 
 
• 
Is fatal or life-threatening; 
 
• 
Requires or prolongs inpatient hospitalization; 
 
• 
Results in persistent or significant disability/incapacity; 
 
• 
Constitutes a congenital anomaly or birth defect; or 
 
• 
Jeopardizes the participant and requires medical or surgical intervention to prevent 
one of the outcomes listed above.  
Events not considered to be serious adverse events are hospitalizations for: 
 
• 
Routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition, or for elective procedures. 
 
• 
Elective or pre-planned treatment for a pre-existing condition that did not worsen. 
 
• 
Emergency outpatient treatment for an event not fulfilling the serious criteria outlined 
above and not resulting in an inpatient admission. 
 
• 
Respite care. 
 
13.8.3 Expectedness 
Expected:  Expected adverse events are those that have been previously identified as resulting 
from administration of the agent.  For the purposes of this study, an adverse event is considered 
expected when it appears in the current adverse event list, the Investigator’s Brochure, the 
package insert or is included in the informed consent document as a potential risk. 
 
Unexpected:  An adverse event is considered unexpected when it varies in nature, intensity or 
frequency from information provided in the current adverse event list, the Investigator’s Brochure, 
the package insert or when it is not included in the informed consent document as a potential risk. 
13.8.4 Attribution 
Attribution is the relationship between an adverse event or serious adverse event and the study 
treatment.  Attribution will be assigned as follows: 
 
• 
Definite – The AE is clearly related to the study treatment. 
 
• 
Probable – The AE is likely related to the study treatment. 
 
• 
Possible – The AE may be related to the study treatment. 
 
• 
Unlikely – The AE is doubtfully related to the study treatment. 
 
• 
Unrelated – The AE is clearly NOT related to the study treatment.

13.9.  Reporting Procedures 
13.9.1 General Considerations 
All adverse events will be captured on a centralized electronic case report form called ON-line 
Clinical Oncology Research Environment = Oncore:  
< http://www.vicc.org/ct/research/oncore.php >.  
 
Oncore is a highly secure, web based, cancer specific, and customizable system that provides 
fully integrative clinical data management and study administration capabilities developed in an 
ongoing collaborative effort with NCI designated Comprehensive Cancer Centers.  It fully 
integrates study administration functionality including protocol tracking, patient registration, NCI 
reporting, review committee tracking, and SAE tracking, with clinical data management 
functionality including electronic case report forms (eCRF) design, clinical data capture, protocol 
and regulatory compliance monitoring.  Specified members at each participating site will submit 
all regulatory documents to the Coordinating Center. 
 
Investigators should use correct medical terminology/concepts when reporting AEs or SAEs, and 
avoid colloquialisms and abbreviations.  If known at the time of reporting, a diagnosis should be 
reported rather than individual signs and symptoms (e.g. record only liver failure or hepatitis 
rather than jaundice, asterixis, and elevated transaminases).  However, if a constellation of signs 
and/or symptoms cannot be medically characterized as a single diagnosis or syndrome at the 
time of reporting, it is acceptable to report the information that is currently available.  If a 
diagnosis is subsequently established, it should be reported as follow-up information. 
 
All deaths that occur during the protocol-specified AE reporting period, regardless of attribution, 
will be reported to the appropriate parties.  When recording a death, the event or condition that 
caused or contributed to the fatal outcome should be reported as the single medical concept.  If 
the cause of death is unknown and cannot be ascertained at the time of reporting, report 
“Unexplained Death.”  Deaths that occur during the protocol specified adverse event reporting 
period that are attributed by the investigator solely to progression of disease should be recorded 
only in the study eCRF and not reported as an SAE. 
 
A pre-existing medical condition is one that is present prior to initiation of protocol specified 
treatment.  Such conditions should be reported as medical and surgical history.  A pre-existing 
medical condition should be re-assessed throughout the trial and reported as an AE or SAE only 
if the frequency, severity, or character of the condition worsens during the study.  When reporting 
such events, it is important to convey the concept that the pre-existing condition has changed by 
including applicable descriptors (e.g., “more frequent headaches”). 
 
Any AE that results in hospitalization or prolonged hospitalization should be documented and 
reported as an SAE.  If a patient is hospitalized to undergo a medical or surgical procedure as a 
result of an AE, the event responsible for the procedure, not the procedure itself, should be 
reported as the SAE.  For example, if a patient is hospitalized to undergo coronary bypass 
surgery, record the heart condition that necessitated the bypass as the SAE. 
 
Hospitalizations for the following reasons do not require reporting: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical 
procedures for pre-existing conditions; or 
• 
Hospitalization or prolonged hospitalization required to allow efficacy measurement for 
the study; or 
• 
Hospitalization or prolonged hospitalization for scheduled therapy of the target disease 
of the study.

13.9.2 Serious Adverse Events 
All serious adverse events, regardless of causality to study drug, will be reported to the Principal 
Investigator and/or the Study Coordinator at each institution, and also to the Coordinating Center. 
 
All serious adverse events must be reported to the Coordinating Center within 24 hours of the 
investigator becoming aware of the event.  Events should be reported using the Vanderbilt SAE 
form, located in the packet of supplemental forms.  This form must be fully completed and 
emailed (preferred), faxed, or scanned to: 
 
ATTN:  VICC CTSR Personnel 
EMAIL:  Coordinating.Center@vumc.org 
FAX:  (615) 875-0040 
 
If SAE documents are faxed, the Coordinating Center must be notified via email as well.  Follow-
up information must also be reported within 24 hours of receipt of the information by the 
investigator. 
If only limited information is initially available, follow-up reports are required.  (Note:  Follow-up 
SAE reports should include the same investigator term(s) initially reported.)  If an ongoing SAE 
changes in its intensity or relationship to study drug or if material new information becomes 
available, a follow-up SAE report should be sent.  All SAEs should be followed to resolution or 
stabilization. 
 
The Coordinating Center will disseminate information regarding serious adverse events to the 
participating sites as described in FDA guidance only in the case that the event(s) is/are 
unexpected, and is/are believed to be related (i.e., possibly, probably or definitely) to the study 
device/medication.   
 
All Serious Adverse Events (SAEs), whether related or not related to study drug, that 
occur following the patient’s written consent to participate in the study through 100 days 
after the patient’s last dose of protocol-indicated nivolumab, relatlimab or ipilimumab 
must be reported to the Coordinating Center (which will report such event also to BMS 
Worldwide Safety).  
 
Although pregnancy, overdose, potential drug-induced liver injury (DILI), and cancer are not 
always serious by regulatory definition, these events must be handled as SAEs. 
 
Vanderbilt University Medical Center acting as the Coordinating Center will be responsible for 
reporting of events to BMS and the FDA as appropriate (outlined below). 
13.9.3 Institutional Review Board 
All adverse events and serious adverse events will be reported to the IRB per current institutional 
standards.  If an adverse event requires modification of the informed consent, these modifications 
will be provided to the IRB with the report of the adverse event.  If an adverse event requires 
modification of the study protocol, these modifications will be provided to the IRB as soon as is 
possible. 
 
13.9.4 Food and Drug Administration (FDA) 
In this trial, unexpected serious adverse events believed to be definitely, probably, or possibly 
related to study treatment (as determined by the sponsor-investigator) will be reported to the FDA 
via MedWatch 3500A, currently available at: 
< https://www.fda.gov/downloads/AboutFDA/ReportsManualsForms/Forms/UCM048334.pdf >.  
Submissions by the sponsor can be submitted via fax or email and must be addressed to the 
Regulatory Project Manager in the FDA review division that has responsibility for review of the 
IND.  The Coordinating Center will be responsible for correspondence regarding adverse events 
with the FDA for all participating sites.

13.9.5 Bristol-Myers Squibb (BMS) 
Vanderbilt University Medical Center acting as the coordinating center will be responsible for 
reporting to BMS any Serious Adverse Event (SAE), whether related or not related to study drug, 
that occurs during the SAE reporting period (as defined above in Section 13.9.2). 
 
Within 24 hours after the sponsor-investigator (or designee) initially receives the safety 
information, the Coordinating Center will report the SAE to BMS on the MedWatch, Pregnancy 
Surveillance Form (provided upon request from BMS), or site SAE form approved by BMS; via 
email or facsimile to the following: 
 
  
 
 
 
 
 
Follow-up SAE reports received by the Coordinating Center should be sent within 24 hours or 1 
Business Day to BMS using the same procedure used for transmitting the initial SAE report.  
 
The Sponsor will reconcile the SAE cases (case level only) transmitted to BMS Global 
Pharmacovigilance (Worldwide.Safety@bms.com).  
• 
The Investigator will request from BMS GPV&E, aepbusinessprocess@bms.com the SAE 
reconciliation report and include the BMS protocol number every 3 months and prior to 
data base lock or final data summary 
• 
GPV&E will send the investigator the report to verify and confirm all SAEs have been 
transmitted to BMS GPV&E. 
• 
The data elements listed on the GPV&E reconciliation report will be used for case 
identification purposes. If the Investigator determines a case was not transmitted to BMS 
GPV&E, the case should be sent immediately to BMS (Worldwide.Safety@bms.com). 
 
In addition to the Sponsor Investigator’s responsibility to report events to their local HA, 
suspected serious adverse reactions (whether expected or unexpected) shall be reported by BMS 
to the relevant competent health authorities in all concerned countries according to local 
regulations (either as expedited and/or in aggregate reports). 
 
In accordance with local regulations, BMS will notify sponsor investigators of all reported SAEs 
that are suspected (related to the investigational product) and unexpected (ie, not previously 
described in the IB). An event meeting these criteria is termed a Suspected, Unexpected Serious 
Adverse Reaction (SUSAR). Sponsor investigator notification of these events will be in the form 
of either a SUSAR Report or a Semi-Annual SUSAR Report.

14.  CORRELATIVE STUDIES 
 
14.1.  Overview 
Patients with MHC-II expressing melanomas, defined as those with ≥5% expression on tumor cells 
by pathologist assessment using immunohistochemistry analysis of MHC-II/HLA-DR, will be 
assigned to nivolumab and relatlimab, whereas those who are negative (<5%) are assigned to 
nivolumab and ipilimumab.  This will be assessed from fresh or archival tissue obtained since any 
other systemic therapy.  Additional tissue for correlative assessment will be collected or requested 
according to Table 5:

1  Arm A cycle (28 days): On Day 1 of each 28-day cycle, all patients are scheduled to receive nivolumab 
and relatlimab intravenously. 
2  Arm B 4 initial cycles (21 days): On Day 1 of cycles 1-4, all patients are scheduled to receive nivolumab 
and ipilimumab intravenously. 
3  Arm B subsequent cycles (28 days): Starting with cycle 5, patients will receive nivolumab only, 
intravenously every 4 weeks. 
4  Archival or fresh tumor tissue: Mandatory tissue at baseline required for analysis of tumor for MHC-II 
status (</= 28d prior to c1d1). Tumor tissue must be received at VUMC for MHC-II testing in order for the 
participant to be enrolled in the correct arm of the study. (Note the Tissue Requisition Form in the Lab 
Manual.) Archival tissue [paraffin block(s) or unstained slides from paraffin block(s)] from the primary 
tumor and/or a metastatic site must be available prior to initiating treatment, or patient must be willing to 
undergo a fresh pre-treatment standard of care tumor biopsy. Within 28 days prior to initiating treatment, 
the screening team must have documentation that an archival or fresh tumor specimen has been 
requested from a local or outside facility. Physical possession and centralized testing of requested tissue 
is required prior to initiating study treatment because all patients in this study are being stratified by 
MHC-II status, based on centralized testing performed at Vanderbilt. 
5  Fresh biopsy of lesion amenable to safe biopsy from a primary lesion or metastatic site, performed 
approximately 6 weeks following initiation of protocol-indicated treatment: Arm A: Fresh biopsy on Cycle 
2, Day 15 (±7 days); Arm B: Fresh biopsy on Cycle 3, Day 1 (±7 days).

6  Peripheral blood samples for exploratory analysis including biomarker and possible PD research to be 
obtained at time points indicated, consistent with Section 7. Note that 2 of these time points also 
correspond to days when fresh tumor biopsy is also intended (i.e. Cycle 2, Day 15 in Arm A; and Cycle 3, 
Day 1 in Arm B). To accommodate scheduling, a ±7 day window for the fresh on-study biopsy is allowed; 
therefore, a similar ±7 day window is also applicable to the research blood draws scheduled for these 
two time points, in order for the research blood to be collected ideally on the same day as the fresh 
biopsy (and ideally PRIOR to the biopsy procedure). 
 
14.2.  Tumor Tissue 
MHC-II testing for treatment assignment will be tested using archival tissue obtained since last 
systemic therapy or using fresh biopsies.  Fresh biopsies prior to treatment will be obtained 
whenever possible, even if archival tissue is available.  Available tissue will also be tested for RNA 
sequencing, immunofluorescence testing (including PD-L1, CD8, CD4, and others). 
 
When at all reasonably possible, the same archival tissue originally used for initial screening 
should also be used for additional correlative analysis.  Fresh biopsies are still encouraged even if 
sufficient archival tissue for MHC-II testing is available. 
 
If residual archival tumor tissue is unavailable or insufficient from the time point previously used for 
initial MHC-II testing, then alternative tissue from the most recent biopsy/specimen should be used 
for correlative research. 
 
Every reasonable effort should be made to obtain additional pre-treatment archival slides to 
assess tumor heterogeneity and dynamic changes over time. 
 
14.3.  Peripheral Blood 
Blood from each patient at Pre-Treatment (C1D1), On-Treatment (as specified in section 7), and at 
EOT/Progression is required.  Subjects who discontinue study related therapy can continue to 
have correlative blood samples collected. 
 
Approximately 47mL of peripheral blood is anticipated to be drawn for correlative research at each 
of 7 time points in Study Arm A and Study Arm B: c1d1, c1d15, c2d15, c4d1, c14d1, EOT, and 
30d F/U (Arm A); and c1d1, c1d15, c3d1, c5d1, c15d1, EOT, and 30d F/U (Arm B). 
 
14.4.  Specimen Banking 
Any leftover study tissue or blood samples may be stored for future research studies.  The 
subjects will consent to the future use of samples in the consent form for the study.  All future use 
as part of residual or repository specimens collected in this trial for purposes not prospectively 
defined will require review and approval by the Institutional Review Board according to its 
established policies, whether the specimens are stored in a central site or at a local institution or in 
a virtual repository. 
 
15.  DATA SAFETY AND MONITORING 
 
15.1.  Data Management and Reporting 
Participating institutions will be collaborating with Vanderbilt for patient accrual.  Data will be 
collected using a centralized electronic case report form called ON-line Clinical Oncology 
Research Environment = Oncore (http://www.vicc.org/ct/research/oncore.php).  Oncore is a highly 
secure, web based, cancer specific, and customizable system that provides fully integrative clinical

data management and study administration capabilities developed in an ongoing collaborative 
effort with NCI designated Comprehensive Cancer Centers.  It fully integrates study administration 
functionality including protocol tracking, patient registration, NCI reporting, review committee 
tracking, and SAE tracking, with clinical data management functionality including electronic case 
report forms (eCRF) design, clinical data capture, protocol and regulatory compliance monitoring.  
Also the system is capable of storing basic protocol information (e.g., IRB approval dates, dates 
for annual renewals) and clinical trial research data.  Oncore allows the investigator to define 
specific protocol requirements and generate data collection forms.  Creation of the data collection 
form is done with a single button click after the parameters of an individual protocol have been 
specified.  Oncore permits specification of study protocols, management of patient enrollment, 
clinical data entry and viewing, and the generation of patient or study-specific reports based on 
time stamping.  OnCore is embedded with a comprehensive domain repository of standard 
reference codes and forms to promote standardization.  The sources for the repository include 
CDUS, CTC, CDEs from NCI, ICD, MedDRA and various best practices from contributing NCI-
designated Comprehensive Cancer Centers.  OnCore provides several reporting features 
specifically addressing NCI Summary 3 and Summary 4 and other reporting requirements.  Data 
may also be exported in a format suitable for import into other database, spreadsheets or analysis 
systems (such as SPSS).  This system will be used to manage all VICCC clinical trials data.  
OnCore is maintained and supported in the VICC Clinical and Research Informatics Resource. 
 
15.2.  Meetings 
This study will be monitored by the VICC melanoma research team, which includes medical 
oncologists, research nurses, data managers, and regulatory specialists.  The team meets on a 
regular basis to discuss AEs/SAEs, accrual, compliance, safety issues, adherence to protocol, etc. 
pertaining to cancer studies conducted by the team.  In addition, meetings between the 
Coordinating Center and research teams at participating sites may be scheduled as necessary, in 
order to discuss relevant issues related to the trial (e.g. AEs/SAEs, accrual, compliance, safety 
issues, adherence to protocol, reviews). 
 
15.3.  Monitoring 
The Vanderbilt-Ingram Cancer Center (VICC) oversees patient safety and data monitoring for its 
investigator-initiated and NIH-NCI funded clinical trials through its Data and Safety Monitoring 
Committee (DSMC).  The purpose of the DSMC is to ensure the efficient implementation and 
management of the VICC Data and Safety Monitoring Plan (DSMP).  The Committee maintains 
authority to intervene in the conduct of studies as necessary to ensure clinical research performed 
at VICC achieves the highest quality standards. 
 
The VICC DSMC meets on a quarterly basis and ad hoc to discuss data and safety monitoring of 
clinical trials and to oversee the VICC DSMP.  Internal audits for compliance with adverse event 
reporting, regulatory and study requirements, and data accuracy and completion are conducted 
according to the VICC DSMP according to study phase and risk.  The committee reviews all 
serious adverse events (SAE) on Vanderbilt sponsored investigator-initiated studies on a quarterly 
basis and provides DSMC SAE review reports to the Vanderbilt IRB. 
 
15.4.  Data Handling and Record Keeping 
An electronic case report form (eCRF) is required and must be completed for each included 
participant.  The completed dataset should not be made available in any form to third parties, 
except for authorized representatives of appropriate Health/Regulatory Authorities, without written 
permission from Vanderbilt. 
 
To enable evaluations and/or audits from health authorities and Vanderbilt, each site investigator 
agrees to keep records including:  The identity of all participants (sufficient information to link

75 of 100 
 
records; e.g., hospital records), all original signed informed consent forms, copies of all source 
documents, and detailed records of drug disposition.  To comply with international regulations, the 
records should be retained by the investigator in compliance with regulations. 
 
Queries resulting from review of the eCRFs will be generated for the site and corrections will be 
made by the study site personnel.  This will be done on an ongoing basis. 
 
16.  REGULATORY CONSIDERATIONS 
 
16.1.  Protocol Review and Amendments 
Information regarding study conduct and progress will be reported to the Institutional Review 
Board (IRB) per current institutional standards at each participating study site. 
 
The trial will not be initiated until there is approval by the local IRB of the protocol, informed 
consent document and any other material used to inform the patient about the nature of the trial.  
The IRB should be duly constituted according to local regulatory requirements.  The investigator 
will inform the IRB of the progress of the trial at least yearly. 
 
Any changes to the protocol will be made in the form of a written amendment and must be 
approved by the sponsor-investigator and the IRB of each institution prior to local implementation.  
All amendments will also be submitted as necessary to the FDA by the sponsor-investigator (or 
designee). 
 
Protocol changes to eliminate an immediate hazard to a trial patient may be implemented by the 
investigator immediately.  The investigator must then immediately inform the local IRB; and the 
sponsor-investigator (or designee), who will communicate as appropriate with the FDA. 
 
The sponsor-investigator (or designee) is responsible for the coordination and development of all 
protocol amendments.  Once approved by the sponsor-investigator, Vanderbilt will disseminate 
this information to the participating centers. 
 
16.2.  Informed Consent 
The investigator (or designee) will explain to each subject the nature of the study, its purpose, the 
procedures involved, the expected duration, the potential risks and benefits involved and any 
discomfort it may entail.  Each subject will be informed that participation in the study is voluntary, 
that s/he may withdraw from the study at any time, and that withdrawal of consent will not affect 
subsequent medical treatment or relationship with the treating physician(s) or institution.  The 
informed consent will be given by means of a standard written statement, written in non-technical 
language, which will be IRB approved.  The subject should read and consider the statement 
before signing and dating it, and will be given a copy of the document.  No subject will enter the 
study or have study-specific procedures done before his/her informed consent has been obtained. 
 
In accordance with the Health Information Portability and Accountability Act (HIPAA), the written 
informed consent document (or a separate document to be given in conjunction with the consent 
document) will include a subject authorization to release medical information to the study sponsor 
and supporting agencies and/or allow these bodies, a regulatory authority, or Institutional Review 
Board access to subjects’ medical information that includes all hospital records relevant to the 
study, including subjects’ medical history.

16.3.  Ethics and GCP 
This study will be carried out in compliance with the protocol and Good Clinical Practice, as 
described within: 
 
1. ICH Harmonized Tripartite Guidelines for Good Clinical Practice 1996. 
2. US 21 Code of Federal Regulations dealing with clinical studies (including parts 50 and 
56 concerning informed consent and IRB regulations). 
3. Declaration of Helsinki, concerning medical research in humans (Recommendations 
Guiding Physicians in Biomedical Research Involving Human Subjects, Helsinki 1964, 
amended Tokyo 1975, Venice 1983, Hong Kong 1989, Somerset West 1996). 
 
The investigator agrees to adhere to the instructions and procedures described within the above 
and thereby to adhere to the principles of Good Clinical Practice with which the above conform. 
 
16.4.  Confidentiality 
It is the responsibility of the investigator to ensure that the confidentiality of all patients 
participating in the trial and all of their medical information is maintained.  Case report forms 
(CRFs) and other documents submitted to regulatory authorities must not contain the name of a 
trial patient.  All patients in the trial will be identified by a unique identifier which will be used on all 
CRFs and any other material submitted to regulatory authorities.  All case report forms and any 
identifying information must be kept in a secure location with access limited to the study staff 
directly participating in the trial. 
 
16.5.  Study Termination 
The sponsor-investigator reserves the right to terminate the study at any site and at any time.  
Reasons for study termination may include, but are not limited to, the following: 
 
• 
Investigator non-compliance with the protocol, GCP or regulatory requirements. 
• 
Insufficient enrollment. 
• 
Safety concerns. 
• 
Decision by suppliers to modify or discontinue the availability, development or 
manufacture of protocol-indicated treatment. 
• 
A request to discontinue the study by the IRB or FDA. 
 
The sponsor-investigator will promptly notify investigators, the IRB and FDA if the study is 
terminated for any reason.

17.  STUDY COORDINATION 
 
17.1.  Trial Compliance 
This is an investigator-initiated study.  The Principal Investigator, Elizabeth Davis, M.D. (who may 
also be referred to as the Sponsor-Investigator), is conducting the study as acting as the sponsor.  
Therefore, the legal and ethical obligations of the Principal Investigator include both those of a 
sponsor and those of a principal investigator. 
 
Vanderbilt is the Coordinating Center for this study.  All aspects of the study will be carefully 
monitored by the Coordinating Center for compliance with applicable government regulations with 
respect to current GCP and standard operating procedures. 
 
17.2.  Changes to Protocol and Informed Consent Document 
Any change to the protocol and informed consent document must be reviewed and approved by 
the Coordinating Center before being submitted to the Institutional Review Board/Independent 
Ethics Committee at participating institutions.  Amendments should not be implemented until all 
necessary approvals have been obtained, except when necessary to eliminate an immediate 
hazard to study subjects. 
 
17.3.  Protocol Deviations 
The Coordinating Center is responsible for implementing and maintaining quality assurance and 
quality control to ensure that studies are conducted according to the protocol, GCP, and all 
applicable regulatory requirements.  A protocol deviation is any noncompliance with the protocol.  
Noncompliance can be on the part of the study participant, the investigator, or the study site staff.  
Deviations to the protocol are not permitted except when necessary to eliminate an immediate 
hazard to study subjects. 
 
17.4.  Monitoring and Quality Assurance 
As the Coordinating Center, Vanderbilt has responsibilities to health authorities to take all 
reasonable steps to ensure the proper conduct of the study with regard to ethics, protocol 
adherence, integrity, validity of the data recorded on the CRFs, and adherence to regulations 
regarding Good Clinical Practice (GCP) and the protection of human subjects. 
 
In accordance with applicable regulations, GCP, and Coordinating Center procedures, sites will be 
contacted prior to the start of the study to review with site staff the protocol, study requirements, 
and site responsibilities to satisfy regulatory, ethical, and Coordinating Center requirements. 
 
During the course of the study, the Coordinating Center will routinely monitor the sites for protocol 
compliance, compare CRFs with original source documents from individual subjects, assess drug 
accountability, and ensure that the study is being conducted according to the pertinent regulatory 
requirements.  The review of subject medical records will be performed in a manner to ensure that 
subject confidentiality is maintained.  Monitoring visits will primarily be conducted remotely, and 
sites are required to provide the appropriate source documentation in order to allow for proper 
oversight per GCP.  Investigators must agree to cooperate with the Coordinating Center to ensure 
that any problems detected are resolved.

17.5.  Data Verification 
Data will be collected via eCRFs and entered into the database per Coordinating Center 
guidelines.  The Coordinating Center will check data accuracy by performing source data 
verification.  Source data verification is a direct comparison of the entries made on the CRFs 
against the appropriate source documentation.  This will be conducted remotely, with the 
possibility of on-site verification periodically.  Discrepancies in the data will be brought to the 
attention of the investigator and/or the investigator’s staff.  Any necessary corrections will be made 
directly to the eCRFs or via queries by the investigator and/or the investigator’s staff. 
 
17.6.  Study Documentation 
Each participating site is responsible for submitting copies of all relevant regulatory documentation 
to the Coordinating Center.  The required documents include, but are not limited to the following:  
local IRB approvals (i.e., protocol, consent form, amendments, patient brochures, recruitment 
material, etc.), each participant’s informed consent, enrollment form, eligibility checklist, summary 
of unanticipated problems or protocol deviations, and documentation of expertise of the 
investigators.  The Coordinating Center will provide each participating site with a comprehensive 
list of the necessary documents.  Specified members at each participating site will submit all 
pertinent regulatory documents to the Coordinating Center, for storage in a secure location.  It is 
the responsibility of the participating sites to maintain copies of all documentation submitted to the 
Coordinating Center. 
 
17.7.  Closure of the Study 
The Coordinating Center reserves the right to discontinue a site at any time during the study for 
medical or administrative reasons such as: 
 
• 
Unsatisfactory enrollment; 
• 
GCP noncompliance; 
• 
Inaccurate or incomplete data collection; 
• 
Falsification of records; 
• 
Failure to adhere to the study protocol. 
 
17.8.  Records Retention 
U.S. FDA regulations (21 CFR §312.62[c]) require that records and documents pertaining to the 
conduct of this study and the distribution of investigational drug, including CRFs, consent forms, 
laboratory test results, and medication inventory records, must be retained by each Principal 
Investigator for 2 years after marketing application approval.  If no application is filed, these 
records must be kept 2 years after the study is discontinued and the U.S. FDA and the applicable 
national and local health authorities are notified. 
 
Following closure of the study, each participating center will maintain a copy of all site study 
records in a safe and secure location.  The Coordinating Center will inform the investigator at each 
site at such time that the records may be destroyed. 
 
17.9.  Publication 
It is understood that any manuscript or releases resulting from the collaborative research must be 
approved by the sponsor-investigator and will be circulated to applicable participating 
sites/investigators prior to submission for publication or presentation.

18.  STATISTICAL CONSIDERATIONS 
 
18.1.  Primary Endpoint 
To evaluate the efficacy, measured by change in activated GZMB+ CD8+ T-cell density 
intratumorally, of two immunotherapy regimens in patients with advanced melanoma. Patients with 
MHC-II (+) melanoma receive nivolumab plus relatlimab treatment. Patients with MHC-II (-) 
melanoma receive nivolumab plus ipilimumab treatment. 
 
18.2.  Sample Size and Power 
The primary endpoint for this study is change in GZMB+ CD8+ T cell infiltration. A total sample 
size of 36 with 18 in each arm will provide 83% power to detect a difference in mean activated 
CD8+ T cell density change of one standard deviations (e.g., 1 SD=1000 counts/mm2 is roughly 
the effect size for doubling T cell count), with a two-sided significance level of 0.05. Assuming a 
10% dropout rate, a total number of 40 patients is planned for enrollment in the study to ensure 
the study has adequate statistical power for the primary analysis. 
 
18.3.  Secondary Endpoints 
Efficacy for each arm: response rate as measured by RECIST 1.1, progression free survival, and 
overall survival. Survival statistics will be assessed descriptively for each arm and summarized 
with median, 1 year, and 2 year landmark analyses. 
Safety: safety and tolerability of nivolumab plus relatlimab in patients with MHC-II (+) melanoma, 
and of nivolumab plus ipilimumab in patients with MHC-II (-) melanoma. 
 
18.4.  Statistical Analysis Plan 
Patient demographics/other baseline characteristics will be listed by patient and/or summarized 
descriptively by each arm. Categorical data will be presented as frequencies and percentages. For 
continuous data, summary statistics will be presented. Between-group differences will be 
assessed with t-test based on a continuous variable. Nonparametric counterparts, Wilcoxon rank 
sum test, will be used when assumptions for parametric methods are not met. Binary and 
categorical data will be analyzed with chi-squared test or Fisher’s exact test. Multivariable analysis 
will be performed using linear regression model, where the outcome variable is the density of 
activated CD8+ T cell post-treatment and the explanatory variable is the MHC-II status, adjusted 
for baseline T cell density. Median PFS and median OS will be estimated with 95% confidence 
intervals. If the median has not be reached by the end of the follow-up, mean survival will be 
reported instead. Kaplan-Meier curves will be constructed by MHC-II status. Multiple comparison 
issues will be corrected using the Bonferroni’s approach. All statistical analysis will be performed 
using R 3.4.2 or a newer version.

Acceptable Contraception 
 
 
Source:  Clinical Trial Facilitation Group21 (CTFG), 2014. 
 
 
 
For purpose of this study, acceptable birth control methods that can achieve a failure rate 
of less than 1% per year when used consistently and correctly are considered as highly 
effective and include: 
• 
Combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation1: 
− 
oral 
− 
intravaginal 
− 
transdermal 
• 
Progestogen-only hormonal contraception associated with inhibition of ovulation1: 
− 
oral 
− 
injectable 
− 
implantable2 
• 
Intrauterine device (IUD)2 
• 
Intrauterine hormone-releasing system (IUS)2 
• 
Bilateral tubal occlusion2 
• 
Vasectomised partner2,3 
• 
Sexual abstinence4 
 
For purpose of this study, acceptable birth control methods which may not be considered 
as highly effective that result in a failure rate of more than 1% per year include: 
• 
Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the 
primary mode of action 
• 
Male or female condom with or without spermicide5 
• 
Cap, diaphragm or sponge with spermicide5 
 
 
1  Hormonal contraception may be susceptible to interaction with the investigational medicinal product 
(IMP), which may reduce the efficacy of the contraception method. 
2  Contraception methods that in the context of this guidance are considered to have low user dependency. 
3  Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual 
partner of the WOCBP trial participant and that the vasectomised partner has received medical 
assessment of the surgical success. 
4  In the context of this guidance sexual abstinence is considered a highly effective method only if defined as 
refraining from heterosexual intercourse during the entire period of risk associated with the study 
treatments.  The reliability of sexual abstinence needs to be evaluated in relation to the duration of the 
clinical trial and the preferred and usual lifestyle of the subject. 
5  A combination of male condom with either cap, diaphragm or sponge with spermicide (double barrier 
methods) are also considered acceptable, but not highly effective, birth control methods.

A woman of childbearing potential (WOCBP) must agree to use 2 methods of acceptable 
contraception (that are included in the above table in this Appendix 4) with one method highly 
effective and the other method either highly effective or less highly effective, from the time she 
signs consent, and until at least 165 days (24 weeks) after her final dose of nivolumab, relatlimab 
or ipilimumab. 
 
A man able to father children who has a female partner of childbearing potential must agree to use 
2 methods of acceptable contraception (that are included in the above table in this Appendix 4) 
with one method highly effective and the other method either highly effective or less highly 
effective, from the time he signs consent, and until at least 225 days (33 weeks) after his final dose 
of nivolumab, relatlimab or ipilimumab. 
 
A woman of childbearing potential participating in the study must have a negative serum pregnancy test 
during screening and a negative serum or urine pregnancy test ≤ 72 hours prior to her first dose of 
protocol-indicated treatment on Cycle 1, Day 1. 
 
A female is considered to be a “woman of childbearing potential” (WOCBP) following menarche and until 
becoming post-menopausal unless permanently sterile.  Permanent sterilization methods include 
hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. 
 
Women in the following categories are not considered WOCBP: 
 
• 
Premenarchal. 
• 
Premenopausal female 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. 
 
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 (if 
menopausal status is considered with respect to contraception required by the study). 
 
Note:  Females treated with hormone replacement therapy, (HRT) 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 HRT used.  The duration 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. 
 
Male patients able to father children are defined as those who are not surgically sterile (i.e. patient has 
not had a vasectomy). 
 
If able to father children, male participants with a female partner of childbearing potential must agree to 
the following:

• 
Inform any and all partner(s) of their participation in a clinical drug study and the need to comply 
with contraception instructions as directed by the investigator. 
• 
Inform female partner(s) to consider use of effective methods of contraception until the end of 
relevant systemic exposure, defined as 225 days after the end of treatment in the male 
participant. 
• 
Male participants with a pregnant or breastfeeding partner must agree to remain abstinent from 
penile vaginal intercourse or use a male condom during each episode of penile penetration during 
the treatment and until 225 days after the end of study treatment.  
• 
Refrain from donating sperm for the duration of the study treatment and until 225 days after the 
end of study treatment. 
 
A trial physician or clinical designee shall counsel female patients of childbearing potential, and male 
patients able to father children who have a female partner of childbearing potential, regarding the 
importance of pregnancy prevention, the implications of an unexpected pregnancy, and the use of 
acceptable contraception.  At a minimum, applicable patients must agree to the consistent and correct 
use of at least one method of acceptable contraception, as listed in the above table in Appendix 4.

APPENDIX 5   
Response Evaluation Criteria in Solid Tumors (RECIST v1.1)22 
 
Measurability of tumor at baseline 
 
Definitions 
At baseline, tumor lesions/lymph nodes will be categorized measurable or non-measurable as follows: 
 
Measurable: 
 
Tumor lesions:  Must be accurately measured in at least one dimension (longest diameter in the 
plane of measurement is to be recorded) with a minimum size of: 
• 
10 mm by CT scan (CT scan slice thickness no greater than 5 mm). 
 
• 
10 mm caliper measurement by clinical exam (lesions which 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. 
 
Non-measurable: 
 
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:  Leptomeningeal disease, ascites, pleural or pericardial effusion, 
inflammatory breast disease, lymphangitic involvement of skin or lung, abdominal 
masses/abdominal organomegaly identified by physical exam that is not measurable by 
reproducible imaging techniques. 
 
Special considerations regarding lesion measurability: 
 
Bone lesions, cystic lesions, and lesions previously treated with local therapy require particular 
comment: 
 
Bone lesions 
• 
Bone scan, 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. 
 
Cystic lesions 
• 
Lesions that meet the criteria for radiographically defined simple cysts should not 
be considered as malignant lesions (neither measurable nor non-measurable) 
since they are, by definition, simple cysts.

88 of 100 
 
• 
“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 patient, these are preferred 
for selection as target lesions. 
 
Lesions with prior local treatment 
• 
Tumor lesions situated in a previously irradiated area, or other loco-regional 
therapy, are usually not considered measurable unless there has been 
demonstrated progression in the lesion.  Study protocols should detail the 
conditions under which such lesions would be considered measurable. 
 
Specifications by methods of measurements 
 
Measurement of lesions 
 
All measurements should be recorded in metric notation, using calipers if clinically assessed.  All 
baseline evaluations should be performed as close as possible to the treatment start and never 
more than 4 weeks before the beginning of the treatment. 
 
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. 
• 
Clinical lesions:  Clinical lesions will only be considered measurable when they are 
superficial and ≥10 mm diameter as assessed using calipers (e.g. skin nodules).  
For the case of skin lesions, documentation by color photography including a ruler 
to estimate the size of the lesion is suggested.  As noted above, when lesions can 
be evaluated by both clinical exam and imaging, imaging evaluation should be 
undertaken since it is more objective and may also be reviewed at the end of the 
study. 
• 
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. 
• 
CT, MRI:  CT is the best currently available and reproducible method to measure 
lesions selected for response assessment.  This guideline has defined 
measurability of lesions on CT scan based on the assumption that CT slice 
thickness is 5 mm or less.  When CT scans have slice thickness greater than 5 
mm, the minimum size for a measurable lesion should be twice the slice thickness. 
MRI is also acceptable in certain situations (e.g., for body scans). 
• 
Ultrasound:  Ultrasound is not useful in assessment of lesion size and should not 
be used as a method of measurement. 
• 
Endoscopy, laparoscopy:  The utilization of these techniques for objective tumor 
evaluation is not advised.  However, they can be useful to confirm complete 
pathological response when biopsies are obtained or to determine relapse in trials 
where recurrence following CR or surgical resection is an endpoint. 
• 
Tumor markers:  Tumor markers alone cannot be used to assess objective tumor 
response.

• 
Cytology, histology:  These techniques can be used to differentiate between PR 
and CR in rare cases if required by protocol (for example, residual lesions in tumor 
types such as germ cell tumors, where known residual benign tumors can remain).  
When effusions are known to be a potential adverse effect of treatment (e.g., with 
certain taxane compounds or angiogenesis inhibitors), the cytological confirmation 
of the neoplastic origin of any effusion that appears or worsens during treatment 
can be considered if the measurable tumor has met criteria for response or SD in 
order to differentiate between response (or SD) and progressive disease. 
 
Tumor response evaluation 
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.  Only patients with measurable 
disease at baseline should be included in protocols where objective tumor response is the primary 
endpoint.  Measurable disease is defined by the presence of at least one measurable lesion.  Response 
criteria are listed in Table 6 and Table 7: 
 
TABLE 6:  Response Criteria for Evaluation of TARGET Lesions 
 
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 one or more new lesions is also considered 
progression.) 
Stable Disease (SD) 
Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify 
for PD, taking as reference the smallest sum diameters while on study. 
 
TABLE 7:  Response Criteria for Evaluation of NON-TARGET Lesions 
 
Evaluation of Non-target Lesions 
Complete Response (CR) 
Disappearance of all non-target lesions and normalization of tumor marker 
level.  All lymph nodes must be non-pathological in size (< 10 mm short axis) 
Progressive Disease (PD) 
Unequivocal progression of existing non-target lesions.  
(Note:  the appearance of one or more new lesions is also considered 
progression.) 
Non-CR/Non-PD 
Persistence of one or more non-target lesion(s) and/or maintenance of tumor 
marker level above the normal limits.

Evaluation of Best Overall Response 
It is assumed that at each protocol specified time point, a response assessment occurs.  Table 8 provides 
a summary of the overall response status calculation at each time point for patients who have measurable 
disease at baseline.

The best overall response is determined once all the data for the patient is known. 
Best response determination in trials where confirmation of CR or PR IS NOT required:  
 
Best response in these trials is defined as the best response across all time points (for example, 
a patient who has SD at first assessment, PR at second assessment, and PD on last assessment 
has a best overall response of PR).  When SD is believed to be best response, it must also meet 
the protocol specified minimum time from baseline.  If the minimum time is not met when SD is 
otherwise the best time point response, the patient’s best response depends on the subsequent 
assessments.  For example, a patient who has SD at first assessment, PD at second and does 
not meet minimum duration for SD, will have a best response of PD.  The same patient lost to 
follow-up after the first SD assessment would be considered inevaluable. 
 
Best response determination in trials where confirmation of CR or PR IS required: 
 
Complete or partial responses 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 shown in Table 9.

1) 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 (since disease must have 
reappeared after CR).  Best response would depend on whether minimum duration for SD was met.  
However, sometimes ‘CR’ may be claimed when subsequent scans suggest small lesions were likely still 
present and in fact the patient 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.

APPENDIX 6   
Guidelines for the Management of Immune-Related Adverse Events (irAEs) 
 
The following adverse event management algorithms in this appendix are obtained from Version 18 
of the Nivolumab Investigator Brochure, dated 25 June 2019. 
 
These general guidelines constitute guidance to the Investigator.  The guidance applies to all 
immuno-oncology (I-O) agents and regimens. 
 
Where applicable the Approved Label should be used in combination with the protocol and IB for 
guidance around dose modifications and discontinuation. 
 
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 immuno-oncology drug-related adverse events.  The oral 
equivalent of the recommended IV 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 immuno-oncology agent or regimen being used. 
 
Investigators should refer to the most current version of the IB or Approved Label for current 
recommendations for management of a specific Adverse Event of interest.
