This clinical trial is focused on studying treatments for Non-small Cell Lung Cancer (NSCLC), a type of lung cancer that is common and can be challenging to treat. The study is testing several investigational medications, including boserolimab (also known as MK-5890), rolistobart (MK-0482), MK-4830, and pembrolizumab (also known as Keytruda). These medications are given as a solution for infusion, which means they are administered directly into the bloodstream through a vein.
The purpose of the study is to explore how well these investigational agents work when used in combination with pembrolizumab in patients who have advanced NSCLC and have previously been treated with anti-PD-(L)1 therapy, a type of treatment that helps the immune system fight cancer. The study is designed to be flexible, allowing new treatments to be added as they become available. Participants will receive the study medications over a period of time, and their response to the treatment will be monitored by healthcare professionals.
Throughout the study, participants will be closely observed to assess the effectiveness of the treatment and to monitor for any side effects. The study aims to provide valuable information on the potential benefits of these investigational treatments for patients with advanced NSCLC, helping to improve future treatment options for this condition.
