Brief summary
The main goal of this study is to evaluate the antitumor activity of relatlimab and nivolumab in combination in subjects with unresectable or metastatic melanoma who have not received prior treatment with immunotherapy.
Detailed description
This study will evaluate the antitumor activity of anti-LAG3 monoclonal antibody relatlimab and the anti-PD1 monoclonal antibody nivolumab in combination in subjects with unresectable or metastatic melanoma who have not received prior treatment with immunotherapy. The trial is designed with a lead-in phase of 2 cycles (4 week) treatment of either nivolumab, relatlimab, or the combination of nivolumab/relatlimab, followed by a combination phase of nivolumab/relatlimab treatment in all subjects. This lead-in design with accompanying tumor biopsies and peripheral blood analyses will enable mechanistic analyses of the effect of LAG3 and PD1 blockade alone and in combination to enhance understanding of mechanisms of response and resistance. Duration of response, progression free survival, and safety will be assessed as secondary objectives.
Interventions
Relatlimab (BMS-986016) - 10mg/mL formulation to be administered as an intravenous (IV) infusion at 160 mg IV.
Nivolumab (BMS-936558) - 10-mg/mL formulation to be administered as an IV infusion at 480 mg IV.
Combination (Relatlimab + Nivolumab) therapy will be administered by sequential infusion. Nivolumab administered at 480 mg IV followed by infusion of relatlimab at 160 mg IV.

Intervention model description
In the 4-week lead-in phase, subjects will be randomized to one of three arms for 1 cycle (4 weeks) of lead-in treatment with nivolumab, relatlimab, or the combination of nivolumab and relatlimab. Following 1 cycle of lead-in treatment, all subjects will be treated with the combination of relatlimab and nivolumab every 4 weeks.

Per RECIST v1.1, CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

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. |
