Summary

This trial tests Dostarlimab alone or with TSR-022 in patients with advanced but operable melanoma. These drugs help the immune system attack cancer by preventing cancer cells from hiding. The goal is to see if these treatments improve outcomes before and after surgery.

Who is the study for?
Adults with operable melanoma, including primary melanoma with regional metastasis or recurrence, are eligible for this trial. They must have adequate organ function and provide a recent tumor biopsy. Pregnant women and individuals on systemic immunosuppression or with certain autoimmune diseases, other active cancers, or severe psychiatric issues cannot participate.
What is being tested?
The study is testing the effectiveness of Dostarlimab (TSR-042) alone versus its combination with Cobolimab (TSR-022) in treating melanoma before surgery. Participants will be randomly assigned to receive one of these two treatment options.
What are the potential side effects?
Potential side effects include immune-related reactions that could affect various organs, infusion-related symptoms like fever or chills, fatigue, possible hormonal gland problems leading to hormone deficiencies, skin reactions at injection sites and increased risk of infections.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Dostarlimab (TSR-042) and Cobolimab TSR-022 (combination)Experimental Treatment1 Intervention
Pre-Operative Phase: Dostarlimab (TSR-042) 500mg and Cobolimab TSR-022 300mg will be administered through an IV over 30 minutes, on Cycle 1 Day 1 and then again on Cycle 2 Day 1. Post-Operative Phase: Dostarlimab (TSR-042) will be administered through an IV over 30 minutes for 4 doses every 3 weeks (Cycles 3-4), and then 1000mg will be administered through an IV over 30 minutes every 6 weeks for 6 doses (Cycles 5-10) for approximately 48 weeks. TSR-022 will not be administered.
Group II: Dostarlimab (TSR-042) (singly)Experimental Treatment1 Intervention
Pre-Operative Phase: Dostarlimab (TSR-042) 500mg will be administered through an IV over 30 minutes, on Cycle 1 Day 1, and then again on Cycle 2 Day 1. Post-Operative Phase: Dostarlimab (TSR-042) 500mg will be administered through an IV over 30 minutes for 4 doses every 3 weeks (Cycles 3-4) and then 1000mg will be administered through an IV over 30 minutes every 6 weeks for 6 doses (Cycles 5-10) for approximately 48 weeks.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for melanoma include immune checkpoint inhibitors that target proteins such as PD-1 and TIM-3. PD-1 inhibitors, like nivolumab and pembrolizumab, work by blocking the PD-1 receptor on T cells, preventing cancer cells from evading the immune response. TIM-3 inhibitors, which are still under investigation, aim to enhance the immune response by targeting another checkpoint that regulates T cell activity. Combining PD-1 and TIM-3 inhibitors, as in the TSR-042/TSR-022 trial, may provide a more robust activation of the immune system, potentially leading to better control of melanoma. These treatments are crucial for melanoma patients as they offer a targeted approach to boost the body's own defenses against cancer, potentially improving outcomes and survival rates.

Dr. Davar is always so patient with me and takes the time to ensure I understand everything. After my melanoma diagnosis, it's been difficult to process information, but he is very thorough and caring.
