Study of Pembrolizumab (MK-3475) Versus Chemotherapy in Participants With Advanced Melanoma (MK-3475-002/P08719/KEYNOTE-002)
Randomized, Phase II Study of Pembrolizumab (MK-3475) Versus Chemotherapy in Patients With Advanced Melanoma (KEYNOTE 002)
This study was conducted to compare survival using pembrolizumab (SCH 900475, MK-3475) or standard chemotherapy in participants with advanced melanoma (MEL) who had progressed after prior therapy.
Initial Treatment Period:
Participants were initially randomized to receive either low-dose (2 mg/kg) pembrolizumab, higher dose (10 mg/kg) pembrolizumab or Investigator-choice chemotherapy (ICC). The four standard chemotherapy choices were: carboplatin + paclitaxel, paclitaxel alone, dacarbazine, or temozolomide. The randomization to either pembrolizumab or ICC was conducted in an open-label fashion.
The starting pembrolizumab dose was initially blinded to Investigators and participants until Amendment 03. With Amendment 03, all ongoing pembrolizumab participants were to be treated with open label, fixed dose pembrolizumab 200 mg, instead of a weight-based dosing of pembrolizumab.
Switch-to-Pembrolizumab Treatment Period:
Participants who were initially randomized to receive ICC and experienced progressive disease (PD) may have been eligible to switch to receiving pembrolizumab provided they met protocol-specified requirements for switching. Qualified participants were re-randomized to receive either pembrolizumab 2 mg/kg or pembrolizumab 10 mg/kg in a double-blind fashion. Participants who qualified to switch to pembrolizumab must have completed a washout period of ≥28 days from last dose of chemotherapy before receiving pembrolizumab. With Amendment 03, all switched-to-pembrolizumab participants were to be treated with open-label, fixed dose pembrolizumab 200 mg instead of a weight-based dosing of pembrolizumab.

Measure Description |
Time Frame |
---|---|---|
Progression-free Survival (PFS) - Initial Treatment Period
Time Frame: Up to approximately 36 months (Through Final Analysis database cutoff date of 16-Nov-2015)
|
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first.
Per Response Criteria in Solid Tumors version 1.1 (RECIST 1.1), PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.
In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm.
Note: The appearance of one or more new lesions was also considered PD.
Analysis of PFS was based on an integrated radiology and oncology (IRO) assessment and was not planned or conducted for the switch-to-pembrolizumab treatment groups.
Median PFS based on the product limit (Kaplan-Meier) method for censored data is presented.
This was the final analysis for PFS.
