Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessment of the antitumor activity of nivolumab in association with relatlimab independently for each arm	Antitumor activity will be assessed in terms of 6-month progression-free rate and is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), based on RECIST 1.1	6 months
Secondary	Best overall response, independently for each arm	Best overall response is defined as the best response across all time points (RECIST 1.1). The best overall response is determined once all the data for the patient is known (RECIST 1.1)	throughout the treatment period, an expected average of 6 months
Secondary	1-year progression-free survival, independently for each arm	Progression-free survival is defined as the delay between the start date of treatment and the date of progression (as per RECIST 1.1) or death (from any cause), whichever occurs first	1 year
Secondary	2-year progression-free survival, independently for each arm	Progression-free survival is defined as the delay between the start date of treatment and the date of progression (as per RECIST 1.1) or death (from any cause), whichever occurs first	2 years
Secondary	1-year overall survival, independently for each arm	Overall survival is defined as the delay between the start date of treatment and the date of death (of any cause)	1 year
Secondary	2-year overall survival, independently for each arm	Overall survival is defined as the delay between the start date of treatment and the date of death (of any cause)	2 years
Secondary	Growth Modulation Index, independently for each arm	GMI is defined for each patient as the ratio of its PFS on the nivolumab + relatlimab treatment combination to its PFS on the previous line of therapy (Von Hoff 1998)	throughout the treatment period, an expected average of 6 months
Secondary	Safety profile, independently for each arm	Toxicity graded using the Common Terminology Criteria for Adverse Events version 5	throughout the treatment period, an expected average of 6 months
Secondary	Blood cytokines levels	Levels of cytokines in blood will be measured by ELISA	baseline, cycle 1 day 1, cycle 1 day 15, cycle 3 day 1 and progression (each cycle is 28 days)
Secondary	Blood lymphocytes levels	Levels of lymphocytes in blood will be measured by flow cytometry	baseline, cycle 1 day 1, cycle 1 day 15, cycle 3 day 1 and progression (each cycle is 28 days)
Secondary	Blood kynurenine levels	Levels of kynurenine in blood will be measured by ELISA	baseline, cycle 1 day 1, cycle 1 day 15, cycle 3 day 1 and progression (each cycle is 28 days)
Secondary	Tumor immune cells levels	Levels of immune cells in tumor will be measured by immunohistochemistry	before treatment onset and cycle 3 day 1 (each cycle is 28 days)
