Prior treatment with ipilimumab or interferon alfa is allowed. - history of allergic or hypersensitivity reaction to components or excipients of Dostarlimab (TSR-042) and TSR-022, interferon alfa or ipilimumab - known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies). - known history of or screening test that is positive for hepatitis B virus (HBV; eg, HBsAg reactive or HBV DNA detected) or hepatitis C virus (HCV; HCV antibody positive and/or HCV RNA quantitative is detected). Hepatitis C antibody - positive subjects who received and completed treatment for hepatitis C that was intended to eradicate the virus may participate if hepatitis C RNA levels are undetectable. Hepatitis B positive subjects who received and completed treatment for hepatitis B that was intended to eradicate the virus may participate if hepatitis B DNA levels are undetectable.

Detailed Description
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.
