Survival data for Bristol-Myers Squibb Co.'s Yervoy/Opdivo combination in the CheckMate 067 study in frontline melanoma reinforce the regimen's potency, but also revive a debate about whether the regimen should be reserved for select subsets of patients, with others getting enough benefit from Opdivo alone or other treatment options.
