Vemurafenib, Cobimetinib, Atezolizumab, and Tiragolumab in Treating Patients With High-Risk Stage III Melanoma

Summary

This trial studies how well vemurafenib, cobimetinib, and atezolizumab work in treating patients with high-risk stage III melanoma. Vemurafenib and cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab and tiragolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving vemurafenib, cobimetinib, and atezolizumab may work better in treating high-risk stage III melanoma. Giving atezolizumab and tiragolumab together may also work better in treating high-risk stage III melanoma.
