This is a randomized phase II neoadjuvant study comparing neoadjuvant therapy with PD-1 inhibitor Dostarlimab (TSR-042) to the PD-1/TIM-3 inhibitor combination Dostarlimab (TSR-042)/TSR-022 in patients with resectable regionally advanced or oligometastatic melanoma.~Patients with stage III B/C/D or oligometastatic stage IV A melanoma with lymph node (LN) and/or in-transit and/or oligometastatic disease who have yet to undergo definitive surgery are eligible to enroll.~Suitable patients will be identified pre-operatively. Patients will undergo screening evaluation consisting of systemic/CNS staging scans, tumor biopsy, blood studies to confirm suitability. Subjects will receive neoadjuvant therapy (Dostarlimab (TSR-042) or Dostarlimab (TSR-042)/TSR-022 combination for 6 weeks prior to planned surgery (pre-operative phase). Surgery will occur 1-4 weeks after completion of pre-operative therapy. After recovery from surgery subjects will receive Dostarlimab (TSR-042) (Post-Operative phase) for approximately 48 weeks; for a total of 54 weeks of study drug(s) administration in total.
The purpose of this study is to test the effects of anti-PI-1 inhibitor (TSR-042) or anti-PD-1/anti-TIM-3 combination (TSR-042 / TSR-022) in patients with operable melanoma.
