CheckMate 067
Phase 3 Study of Nivolumab or Nivolumab Plus Ipilimumab Versus Ipilimumab Alone in Previously Untreated Advanced Melanoma (CheckMate 067)
Phase 3N = 945NCT01844505
- Population
- Previously untreated unresectable stage III or IV melanoma
- Design
- Double-blind randomised (1:1:1) phase 3 trial of nivolumab alone, nivolumab plus ipilimumab, or ipilimumab alone in untreated advanced melanoma; randomisation stratified by PD-L1 status, BRAF mutation status and metastasis stage. Progression-free survival and overall survival were co-primary end points. The primary paper states the trial was not designed for a formal statistical comparison between the nivolumab-alone and nivolumab-plus-ipilimumab groups (full text, PMC5698905).
- Primary endpoint
- PFS, OS
- Arms
- Nivolumab plus ipilimumab (experimental, n = 314): Nivolumab 1 mg per kilogram plus ipilimumab 3 mg per kilogram every 3 weeks for four doses, then nivolumab 3 mg per kilogram every 2 weeks
- Nivolumab (experimental, n = 316): Nivolumab 3 mg per kilogram every 2 weeks plus placebo
- Ipilimumab (control, n = 315): Ipilimumab 3 mg per kilogram every 3 weeks for four doses plus placebo
- People
- Larkin J, senior author Wolchok JD
