Overall survival data from CheckMate-069, a phase II trial of a Opdivo and Yervoy combination regimen in patients with previously untreated advanced melanoma, demonstrated a two-year overall survival rate of 69 percent compared to 53 percent for Yervoy alone (HR=0.58 [95% CI: 0.31-1.08]) in patients with BRAF wild-type advanced melanoma.
A group of melanoma experts, joined by three advocacy groups focused on melanoma, has engaged FDA in a public discussion of the challenges of developing new drugs in the refractory setting and the role crossover can play in such trials.
