Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to demonstrate that the nivolumab steady-state level after 3 cycles with a reduced nivolumab dosage (240 mg every 4 weeks) is not lower than the nivolumab concentration 4 weeks after the first 480 mg or 6mg/kg dose. ;Secondary Objective: -Explore PD1 receptor occupancy in PBMCs -Safety of reduced nivolumab doses -Efficacy of reduced nivolumab doses -Pharmacokinetic profile of nivolumab -Cost effectiveness ;Primary end point(s): Difference between the mean trough level 4 weeks after the 3rd nivolumab dose of 240 mg and the mean trough level 4 weeks after treatment start (i.e. 4 weeks after the first 480 mg or 6mg/kg dose);Timepoint(s) of evaluation of this end point: 4 weeks after the 3rd reduced dose of 240 mg and 4 weeks after the 1st dose of 480 mg or 6mg/kg | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - PD-1 receptor occupancy in PBMCs, measured 4 weeks after 3 reduced nivolumab doses - Grade =3 adverse events during reduced doses - Number of patients with new PD during 3 reduced doses - Pharmacokinetic profile of nivolumab - Cost effectiveness ;Timepoint(s) of evaluation of this end point: 4 weeks after the 3rd reduced dose of 240 mg | — |
