This study is referred to as the "umbrella master protocol" for pembrolizumab (MK-3475) in the treatment of non-small cell lung cancer (NSCLC). This pembrolizumab NSCLC umbrella master protocol uses a platform design and consists of this master screening study and additional substudies. Each substudy will enroll a different population of NSCLC participants.
The following pembrolizumab substudies will evaluate the efficacy of different investigational agents in combination with pembrolizumab given in sequence or in combination with pembrolizumab PLUS chemotherapy: * KEYMAKER-U01 Substudy 01A: A Phase 1/2, Umbrella Study With Rolling Arms of Investigational Agents, With Pembrolizumab With or Without Chemotherapy in Treatment-Naive Participants With Stage IV Non-small Cell Lung Cancer (NSCLC) (MK-3475-01A) - NCT04165070 * KEYMAKER-U01 Substudy 2: A Phase 2, Umbrella Study with Rolling Arms of Investigational Agents in Combination with Pembrolizumab…
