Dose-response Analysis of Nivolumab/Relatlimab in the Fixed-dosed Combination 'Opdualag' vs. Cemiplimab/Fianlimab in Relation to the Immunological Response in Tumor and Peripheral Blood for Participants With Unresectable or Metastatic Melanoma: A Corollary Study of HCC 24-056 (NCT06246916)
John Kirkwood
Summary
This translational study will examine the immune effector responses of patients who received a two-drug combination for first line therapy by examining tumor and peripheral blood of participants with unresectable locally advanced or metastatic melanoma.
Description
Cutaneous melanoma is an aggressive skin cancer which, in the metastatic setting, has a historic 5-year survival rate of \<30%. In 2023, about 97,610 new cases of melanoma were estimated to occur in the US, with about 7,990 deaths. GLOBACON reported 324,635 cases of melanoma globally in 2020, which constituted about 1.7% of all cancers and 57,043 melanoma-associated deaths. The parent trial of this corollary study is a randomized, open-label, multicenter phase 3 study comparing the anti-tumor activity of fixed-dose combination (FDC) of fianlimab + cemiplimab versus the FDC of relatlimab + niv…
