Study Evaluating BNT326 Alone or With Other Immunotherapies in Adults With Advanced Solid Tumors

What this Trial Is About

Researchers are evaluating the safety, effectiveness, optimal dose, and behavior of an investigational drug called BNT326, alone or combined with other immunotherapy agents, in adults with advanced solid tumors. This study includes patients with tumors that have either spread metastatic, returned after treatment, or progressed despite previous therapies, across various cancer types such as melanoma, lung cancer, breast cancer, gastric cancer, colorectal cancer, and cervical cancer. Participants are divided into two parts Part 1 tests BNT326 alone in different tumor-specific groups, some with dose randomization to find optimal dosing. Part 2 evaluates BNT326 alone or combined with another investigational drug called pumitamig in several cancer types, with some groups receiving randomized doses and others non-randomized treatments. Treatments are given via intravenous infusion, with some oral medications combined in Part 1. The study includes dose escalation and randomization phases, and treatment can continue for up to 24 months or until disease progression or other reasons. During the study, participants undergo screening, treatment, safety follow-up, efficacy follow-up, and long-term survival monitoring phases. Researchers assess adverse events, treatment responses, disease progression, and drug behavior in the body using clinical evaluations and laboratory tests. Follow-up assessments occur up to approximately 38 months for Part 1 and 48 months for Part 2, with continued treatment possible for those benefiting from the therapy. The study aims to gather comprehensive data on safety, dosing, and effectiveness in this patient population.

A Clinical Study to Test if an Investigational Treatment Called BNT326 is Safe and Potentially Beneficial When Used Alone or in Combination With Other Investigational Treatments Such as BNT327, for People With Advanced Malignant Tumors
