Substudy 02B: Safety and Efficacy of Pembrolizumab in Combination With Investigational Agents or Pembrolizumab Alone in Participants With First Line (1L) Advanced Melanoma (MK-3475-02B)

NCT04305054

Description:

Substudy 02B is part of a larger research study that is testing experimental treatments for melanoma, a type of skin cancer. The larger study is the umbrella study. The goal of substudy 02B is to evaluate the safety and efficacy of investigational treatment arms in participants with 1L advanced melanoma and to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/pembrolizumab monotherapy.

Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Percentage of participants who experience an adverse event (AE)
Time Frame:Up to ~28 months
Safety Issue:
Description:An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experience an AE will be reported.

Secondary Outcome Measures

Measure:Duration of Response (DOR) per RECIST 1.1
Time Frame:Up to ~30 months
Safety Issue:
Description:For participants in the analysis population who demonstrate a confirmed CR (disappearance of all target lesions) or confirmed PR (at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters), DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death due to any cause, whichever occurs first. Responses are according to RECIST 1.1 as assessed by BICR. RECIST 1.1 has been modified for this study to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
