Researchers are evaluating the use of ivonescimab combined with chemotherapy compared to pembrolizumab combined with chemotherapy as the first treatment for people with metastatic non-small cell lung cancer NSCLC. This Phase 3, randomized, double-blind, multiregional study involves around 1600 patients divided into two groups based on NSCLC histology squamous and non-squamous. The main goals are to assess overall survival and progression-free survival, with additional focus on treatment response and safety. Participants are randomly assigned to receive either ivonescimab or pembrolizumab along with platinum-doublet chemotherapy. Both treatments are given as intravenous injections. The two histology groups will be analyzed separately to understand how each treatment works within these subtypes of NSCLC. This design helps compare the effects of the two treatment combinations. During the study, participants will be monitored for survival and disease progression over several years. Safety assessments include tracking side effects from the start of treatment through 30 to 90 days after the last dose or start of other cancer therapies, with follow-up lasting up to two years. The study includes regular evaluations to measure tumor response and overall health, ensuring comprehensive monitoring throughout the participation period.

This research evaluates the long-term safety and effectiveness of pembrolizumab in participants with advanced tumors or hematologic malignancies who have previously taken part in Merck pembrolizumab-based studies. This phase 3 extension study includes participants currently on treatment or in follow-up from parent trials. The study has three phases based on participants prior treatment status First Course Phase, Survival Follow-up Phase, and Second Course Phase, allowing continuation or observation depending on prior participation. Participants receive pembrolizumab alone or combined with other treatments such as standard of care therapies, lenvatinib, olaparib, MK-4280, MK-4280A, or pembrolizumab with berahyaluronidase alfa. Dosing schedules vary by phase and regimen, including intravenous infusions of pembrolizumab every 3 or 6 weeks, oral lenvatinib capsules daily, oral olaparib tablets twice daily, and other biologics administered intravenously or subcutaneously. The study allows up to 35 doses in the First Course Phase and fewer doses in the Second Course Phase, with treatment durations adjusted for crossover eligibility and combination therapies. Participants are monitored through regular treatment visits involving drug administration and follow-up assessments. Researchers evaluate overall survival up to approximately 10 years, along with progression-free survival, event-free survival, and adverse events including serious and clinically significant side effects. The study includes ongoing safety monitoring up to around 40 months post-treatment. Participants remain under observation for long-term outcomes and potential treatment effects for many years after enrollment.
