CheckMate 067 (N vs I ; all population), 2015 NCT01844505
nivolumab alone (n=316) vs. ipilimumab alone (n=315)
randomized controlled trial
nivolumab
nivolumab at a dose of 3 mg per kilogram every 2 weeks (plus ipilimumab-matched placebo)
ipilimumab
ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses (plus nivolumab-matched placebo)
mML - L1 - all population
Other eligibility criteria included known BRAF V600 mutation status
double-blind
137 cancer centres in 21 countries
P3/ two sided test procedure without interim analysis (but OS prolonged) (efficacy endpoints were based on the intent-to-treat population and formal co-primary endpoint analyses were conducted at two different prespecified time points (separately for progression-free survival and overall survival) per the study protocol, as described previously)3 arms // repartition : OS 0.02/ARM (N vs I, NI vs I), PFS 0.005/ARM (N vs I, NI vs I), and hierarchical testing procedure for ORR with PFS results (N vs I, NI vs I)
Nivolumab alone or combined with ipilimumab improved progression-free survival (no threshold), as compared with ipilimumab, among previously untreated patients with metastatic melanoma
CheckMate 066, 2015 NCT01721772
nivolumab alone (n=210) vs. dacarbazine (n=208)
randomized controlled trial
nivolumab
Nivolumab at a dose of 3 mg per kilogram of body weight every 2 weeks, plus a dacarbazine-matched placebo every 3 weeks
dacarbazine
1000 mg of dacarbazine per square meter of body-surface area every 3 weeks, plus a nivolumab-matched placebo every 2 weeks.
Treatment continued until there was disease progression, as assessed by the investigator, or an unacceptable level of toxic effects. As a result, the monitoring committee recommended that the study be unblinded and amended to allow patients enrolled in the dacarbazine group to receive nivolumab.
mML - L1 - BRAF wild
exclusion criteria were active brain metastases, ans patients who had received adjuvant therapy previously were not excluded.
double-blind
Europe, Israel, Australia, Canada, and South America
P3/ two sided test procedure with interim analysis. Hierarchy OS then PFS then ORR
Nivolumab was associated with significant improvements in overall survival and progression-free survival, as compared with dacarbazine, among previously untreated patients who had metastatic melanoma without a BRAF mutation
