Lebanon, New HampshireAges 18 years+ - NCT06171269Recruiting
MRI-guided radiation dose reduction for prostate cancer
This trial tests whether using MRI scans to guide radiation can allow lower doses to the healthy parts of the prostate, potentially reducing side effects. It is for men with intermediate- or high-risk prostate cancer that can be seen on MRI and has not spread.
Chicago, IllinoisAges 18 years+ - NCT06974123Enrolling by invitationPhase 1/Phase 2
Testing a new oral drug for radiation proctitis
This trial tests an oral drug called Teslanbaicin for people who have pelvic cancer and developed radiation proctitis (inflammation of the rectum from radiation therapy). The goal is to see if it is safe and helps heal the inflammation.
Xinxiang, HenanAges 18 years+ - NCT06059586Recruiting
Pre-hab program for women getting pelvic radiation for cancer
This trial tests a pre-rehabilitation (pre-hab) program to help women stay stronger before and during pelvic radiation for certain cancers. The goal is to see if it improves quality of life and reduces treatment side effects.
Avon, IndianaAges 18 years+ - NCT02634645Recruiting
Treatment study for Barrett’s pre-cancer or esophageal cancer
This study looks at treatment options for people with Barrett’s esophagus that has progressed to abnormal cell growth (dysplasia) or cancer. It may help doctors compare approaches that use procedures to remove and/or destroy abnormal tissue in the esophagus.
Los Angeles, CaliforniaAges 18–100 - NCT05417737Recruiting
Ozone therapy for chronic pain when standard treatments fail
This study offers a palliative (comfort-focused) ozone treatment to adults with chronic pain when usual treatments don’t work or are too risky. Researchers will check whether adding ozone can help symptoms and whether it’s safe for selected patients.
Las Palmas, Las PalmasAges 18 years+ - NCT07115667RecruitingPhase 2
Radiation and antibody therapy for bone plasmacytoma
This trial tests a new combination of radiation therapy and a bispecific antibody (a drug that helps your immune system attack cancer cells) for people with a single bone plasmacytoma that has only a small number of abnormal cells in the bone marrow. It aims to see if this approach can control the disease better than radiation alone.
TianjinAges 18–78 - NCT05203250Recruiting
Registry for people treated with heavy particles at CNAO
This registry collects information from people who received heavy particle treatments at the CNAO center. It helps researchers understand outcomes over time, as long as you can understand the study and agree in writing.
PaviaAges Any age - NCT07174089Recruiting
New AI tools for nuclear medicine scans and treatments
This study uses artificial intelligence (AI) to improve PET/CT scans and treatments that use radioactive materials (radiopharmaceuticals) labeled with alpha or beta emitters. It may help doctors get better results from these procedures.
Reggio EmiliaAges 18–90 - NCT06708754Recruiting
Light therapy for radiation side effects in head and neck cancer
This study tests if a special light therapy (photobiomodulation) can help reduce tissue stiffness and swelling caused by radiation for head and neck cancer. It may be an option if you finished radiation in the last 3 years and have moderate to severe scarring or swelling.
New York, New YorkAges 18 years+ - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT01684904Recruiting
Proton beam radiation for certain esophagus cancers
This trial studies whether proton therapy can better treat early-to-mid stage esophagus cancer while aiming to reduce side effects to nearby organs. Proton therapy uses a targeted type of radiation, and participants are also checked to be eligible for curative surgery.
Loma Linda, CaliforniaAges 18 years+ - NCT07627334Recruiting
Personalized drug testing for newly diagnosed brain tumors
This trial tests whether customized drug screening on your tumor cells can help doctors choose the best treatment for you. Your tumor cells will be grown in the lab and tested against different drugs to find what works best, combined with short-course radiation therapy.
Vienna, State of ViennaAges Any age - NCT06266832RecruitingPhase 2
Short-course radiation with immunotherapy and chemo for rectal cancer
This trial tests a combination of short-course radiation, an immunotherapy drug (adebrelimab), and chemotherapy (CAPEOX) before surgery to help preserve the rectum in people with MSS/pMMR ultra-low rectal cancer. The goal is to shrink the tumor enough to avoid removing the rectum.
Hangzhou, ZhejiangAges 18 years+ - NCT05224297Recruiting
