This study looks at whether people with certain genetic types of gastrointestinal cancers (stomach, colorectal, or anal) can safely avoid major surgery after immunotherapy. Instead of removing the organ, doctors will monitor closely or do smaller procedures to remove any remainin…

This study tests an experimental drug called IDP-001 in people with advanced or metastatic solid tumors, including certain lung, head and neck, and other cancers. The trial has two phases: first to check safety and find the right dose, then to see if the drug can shrink tumors. A…

This early-stage trial tests a topical ointment called ACU-D1 for HPV-related vulvar and perianal lesions in people with HIV. Nine participants will apply the cream twice daily for 4 weeks. The main goal is to find the safest dose and see if the treatment can boost immune markers…

This study tests whether a probiotic called EXE-346 can help treat anal high-grade squamous intraepithelial lesions (HSIL) and reduce persistent high-risk HPV infection in people living with HIV. The trial will enroll 90 participants who will take the probiotic or a placebo daily…

This phase 2 trial tests whether a daily dexamethasone enema can prevent or reduce acute rectal injury in 40 rectal cancer patients undergoing pelvic radiotherapy. One group starts the enema early (day 10 of radiation), while the other starts only after injury occurs. The goal is…

This study tests a drug called sacituzumab tirumotecan in 20 people with advanced anal or rectal cancer that has spread or cannot be removed and has not responded to other treatments. The goal is to see if the drug can shrink tumors and how safe it is. Participants will receive t…

This study tests an immunotherapy called PDS0101 in 27 adults with both HIV and HPV 16. The goal is to see if it is safe and can strengthen the immune system's response against HPV, which can cause cancers like anal and cervical cancer. All participants will receive three doses o…

This early-phase trial tests whether umbilical cord blood cells can safely help people with chronic radiation enteritis, a painful gut condition caused by cancer radiation therapy. Ten adults who have had pelvic or abdominal radiation will receive three weekly infusions of these …

This study aims to see if a simple blood test can find HPV-related oropharyngeal cancer early in men aged 50 and older who have no symptoms. Researchers will check blood for two markers of HPV and then follow up with those who test positive to find and treat any tumors. If succes…

This study tests whether the HPV vaccine can prevent the return of high-grade squamous intraepithelial lesions (HSIL) in people who have already been treated for them. About 984 adults aged 18–55 with HPV-related HSIL of the cervix, vulva, vagina, penis, or anus will receive eith…
