ADAPT-IT was a multicenter, phase 2 clinical trial with a planned sample size of 60 patients with unresectable melanoma. Patients received two doses of nivo (1 mg/kg) + ipi (3 mg/kg) followed by a computed tomography scan at week 6....Higher baseline IL-6 was observed in non-responders compared to responders (p = 0.03; n = 26) and was associated with shorter PFS (HR for progression or death 1.24; 95% CI: 1.01-1.52; p = 0.04).
