This study tests a new drug called BMX-001 added to standard radiation and chemotherapy for people newly diagnosed with anal cancer. The goal is to see if BMX-001 can reduce severe side effects like rectal bleeding and skin problems while still fighting the cancer. About 24 adult…

This study tests a combination of two drugs—TG4001 (a biologic that targets HPV) and avelumab (an immunotherapy)—in people with advanced HPV-16 cancers that cannot be removed by surgery or cured by radiation. The trial has two phases: first, to find a safe dose, and second, to se…

This study tests whether adding a special bacterial strain (CMTS0515) to a standard fecal transplant can better relieve gut symptoms caused by radiation therapy for cancer. Sixty adults who completed radiation for abdominal or pelvic cancer will receive either the enhanced or sta…

This early-stage trial is testing a new drug called KFA115, either by itself or combined with the immunotherapy Keytruda (pembrolizumab), in 126 people with advanced cancers like lung, skin, kidney, and others. The main goal is to check safety and find the best dose. It is not ye…

This study tests whether giving a lower dose of radiation to nearby lymph nodes can reduce side effects in people with anal cancer who are also receiving chemotherapy. The trial includes 33 adults with locally advanced anal cancer. The goal is to see if this approach lowers toxic…

This early-stage study tests a new treatment called T-Plex for people with advanced solid tumors (like head and neck, cervical, or melanoma) that haven't responded to standard therapies. The treatment uses a patient's own immune cells, which are modified in a lab to recognize and…
