This clinical trial is focused on evaluating the safety and effectiveness of a new treatment called DuoBody®-CD40x4-1BB (also known as GEN1042) for patients with certain types of cancer. The study involves patients with advanced or metastatic forms of melanoma, Non-Small Cell Lung Cancer (NSCLC), Head and Neck Squamous Cell Carcinoma (HNSCC), Pancreatic Ductal Adenocarcinoma (PDAC), and Colorectal Cancer (CRC). The treatment will be tested both on its own and in combination with another medication called pembrolizumab, with or without additional chemotherapy drugs such as fluorouracil, cisplatin, gemcitabine hydrochloride, carboplatin, pemetrexed disodium, and paclitaxel.
The purpose of the study is to determine the most suitable dose of GEN1042 and to assess its ability to fight tumors. The trial will begin with a phase where the dose is gradually increased to find the maximum amount that can be safely given to patients. This is known as the “dose-escalation” phase. After this, the study will expand to include more patients to further evaluate the treatment’s effectiveness against tumors. During the trial, some patients may receive a placebo, which is a substance with no active medication, to compare the effects of the new treatment.
Participants in the study will receive the treatment through an intravenous infusion, which means the medication is given directly into a vein. The trial will monitor the patients for any side effects and measure how well the treatment works in reducing or controlling the cancer. The study aims to provide valuable information on the potential benefits of GEN1042 for treating these types of cancers.
