This clinical trial is focused on studying the effects of a new treatment called MCLA-129 in patients with advanced forms of cancer, specifically Non-Small Cell Lung Cancer (NSCLC) and other types of solid tumors. The study will explore how well MCLA-129 works on its own and in combination with other cancer treatments, including osimertinib, a medication taken orally, and chemotherapy drugs such as paclitaxel, docetaxel, and carboplatin, which are given through an infusion into a vein.
The purpose of the study is to understand the response of the tumors to the treatment, how safe and tolerable the treatment is for patients, and to gather information on how the body processes MCLA-129. The study will also look at how long patients live without the cancer getting worse and the overall survival rate of the patients. The trial will be conducted in phases, starting with a dose escalation phase to find the best dose of MCLA-129, followed by an expansion phase to further evaluate its effects.
Participants in the study will receive MCLA-129 either alone or in combination with other treatments, and some may receive a placebo. The study will monitor the patients’ health and the progression of their cancer over time. This research aims to provide new insights into the treatment of advanced NSCLC and other solid tumors, potentially leading to more effective therapies in the future.
