Recruiting studies
- NCT04428671RecruitingPhase 1
Cemiplimab before and after surgery for high-risk skin cancer
This Phase 1 trial tests the drug cemiplimab given before and after surgery to reduce the chance that high-risk cutaneous squamous cell cancer comes back. You may be a candidate if your cancer is high-risk on pathology or imaging and is planned for surgical removal.
Atlanta, GeorgiaAges 18 years+ - NCT04512846Recruiting
Radiation for large liver cancer, with or without chemo
This trial compares two treatment approaches for large hepatocellular carcinoma (HCC), a type of liver cancer: stereotactic body radiation therapy (SBRT) alone versus SBRT plus TACE, a catheter-based chemo treatment. It may help decide which approach works better for controlling the tumor when surgery isn’t a good option.
BeijingAges 30–80 - NCT06767007RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This trial studies a combination of SBRT (a precise kind of radiation) and an immunotherapy drug (PD-1 antibody) for people whose rectal cancer has come back in the pelvis and cannot be removed by surgery. The goal is to see if this treatment can shrink the tumor or stop it from growing.
Guangzhou, GuangdongAges 18–75 - NCT00992303Recruiting
Collecting tissue samples during radiation for people with cancer
This study collects tissue samples from people with cancer while they are getting radiation therapy. It also includes healthy participants, to help researchers compare samples and better understand cancer and treatment.
Dallas, TexasAges 18 years+ - NCT06434480Recruiting
SBRT for liver cancer with limited growth on first immunotherapy
This trial tests whether a targeted radiation therapy (SBRT) can help people with liver cancer whose disease has only a few new spots growing while on first-line immunotherapy. It aims to see if zapping those spots can control the cancer and delay the need for stronger treatments.
Hong KongAges 18 years+ - NCT06250972RecruitingPhase 3
Radiotherapy for advanced pancreatic cancer with normal CA19-9 after chemo
This trial tests whether giving radiotherapy to the pancreas can help people with advanced pancreatic cancer whose CA19-9 level has dropped to normal after chemotherapy. It's for patients whose cancer is still locally advanced (hasn't spread to distant organs).
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05384496RecruitingPhase 2
Axitinib and nivolumab for advanced mucosal melanoma
This trial studies how well two medicines—axitinib and nivolumab—work for people with advanced melanoma that starts in moist “mucosal” areas (like the mouth, nose, throat, or bowel). It may help shrink tumors and control the disease by boosting the immune system and targeting tumor growth.
Harrison, New YorkAges 18 years+ - NCT07594691Recruiting
Breath-Hold Techniques to Improve Radiation Therapy Accuracy
This trial tests whether holding your breath during imaging scans can help doctors aim radiation therapy more precisely at upper abdominal cancers while protecting nearby healthy organs. The goal is to reduce side effects by improving treatment accuracy.
Toronto, OntarioAges 18 years+ - NCT05915442RecruitingPhase 2
Adenosine blocker plus immunotherapy for limited prostate spread
This Phase 2 study tests a medicine that affects “adenosine” signaling along with an immune checkpoint inhibitor (immunotherapy) in men with hormone-sensitive prostate cancer that has spread in only a small, limited way. It aims to stop or slow that limited spread by helping the immune system work better.
New York, New YorkAges 18–99 - NCT06692556RecruitingPhase 3
Radiation vs monitoring for high-risk skin cancer
This trial compares two strategies after surgery for a type of skin cancer (cutaneous squamous cell carcinoma) that has a high chance of coming back. One strategy gives radiation therapy to the area, while the other just watches and checks for any signs of recurrence. The goal is to see if radiation can prevent the cancer from returning.
Le Puy-en-Velay, Auvergne-Rhône-AlpesAges 18 years+ - NCT05833867RecruitingPhase 1
Bladder cancer trial combining radiation and Sacituzumab
This Phase 1 study tests whether a new bladder-cancer treatment plan—radiation given at the same time as sacituzumab govitecan—can help people with muscle-invasive bladder cancer without starting with traditional chemo/radiation. Because it’s early-stage, the main goal is safety and learning the best way to use this combination to preserve the bladder.
Cleveland, OhioAges 18 years+ - NCT07150715RecruitingPhase 2
Radioactive drug plus precise radiation for recurrent prostate cancer
This trial tests a powerful radioactive drug (either alpha or beta) combined with precise radiation to treat prostate cancer that has come back in a few spots outside the prostate. It may help men whose cancer is still hormone-sensitive and has not spread widely.
Los Angeles, CaliforniaAges 18 years+ - NCT06439888RecruitingPhase 1/Phase 2
Immune cells plus radiation for limited-stage cancer spread
This trial tests whether giving immune-supporting cells (lymphocytes) alongside focused radiation (SBRT) can help control limited cancer spread. People with 1 to 5 small tumors that can all be radiated within two weeks may be eligible.
LyonAges 18 years+ - NCT06463262Recruiting
Personalized markers for chordoma before surgery and radiation
This trial tests whether analyzing blood and tumor samples before and after radiation and surgery can help find personalized markers for chordoma. It is for patients with chordoma of the skull base, spine, or sacrum who will receive radiation before surgery.
Baltimore, MarylandAges 18 years+ - NCT06461819RecruitingPhase 2
Higher radiation dose for low-to-intermediate prostate cancer
This trial tests if giving a higher dose of radiation in fewer sessions, while using SpaceOAR to protect the rectum, is safe for men with low-to-intermediate risk prostate cancer that hasn't spread.
SeoulAges 20 years+ - NCT04491929Recruiting
Radiation treatment for colon cancer in the liver using tiny beads
This trial studies a targeted liver radiation procedure that uses tiny radioactive beads to treat colon cancer spread mostly in the liver. It may help people whose liver tumors cannot be removed or treated with other common local treatments, but it has several safety and “screening” checks.
Aarhus N, DanmarkAges 18 years+ - NCT06828380RecruitingPhase 2
Immunotherapy with or without radiation for liver cancer
This trial tests whether using immunotherapy alone works as well as immunotherapy combined with radiation for liver cancer that has spread into major blood vessels. The goal is to find the best treatment option for people with this specific type of advanced liver cancer.
GoyangAges 19 years+ - NCT04656041RecruitingPhase 2
Test chemo with radiation for gastroesophageal cancer
This Phase 2 study tests a combination of chemotherapy (5-FU/leucovorin plus irinotecan and oxaliplatin) together with radiation for certain types of esophagus/stomach-junction cancer. It may help shrink tumors and control cancer that is locally advanced but not spread to distant organs.
Boston, MassachusettsAges 18 years+ - NCT06835725RecruitingPhase 2
Comparing two prostate radiation schedules for intermediate risk
This trial compares giving radiation in 2 treatments versus 5 treatments for prostate cancer that hasn't spread. It's for men with low or intermediate risk prostate cancer who are healthy enough to undergo a short course of targeted radiation.
Surrey, British ColumbiaAges 18 years+ - NCT06997094RecruitingPhase 1
Decitabine plus standard therapy for HPV-negative head and neck cancer
This trial tests whether adding the drug decitabine to standard treatment (surgery and possibly radiation) can help people with a type of head and neck cancer not caused by HPV. You would receive decitabine before surgery, and then continue with standard care after.
Jacksonville, FloridaAges 18 years+ - NCT06705127RecruitingPhase 2
Radiation, chemo, and immunotherapy for HR+ breast cancer
This trial tests if giving radiation first, then chemo with an immunotherapy drug called Toripalimab, can help treat a certain type of breast cancer that has not spread to other organs. It is for people with hormone receptor positive, HER2 negative breast cancer that is growing fast.
Hangzhou, ZhejiangAges 18–75 - NCT07744074Recruiting
Carbon-ion radiation for large chest tumors
This trial tests a new type of radiation using carbon ions to treat large tumors in the chest that have come back or not responded to prior treatments. It aims to see if this therapy is safe and effective for people who have few options.
Hangzhou, ZhejiangAges 18 years+ - NCT07101679RecruitingPhase 2
Study of radiation, chemo, and immunotherapy for advanced pancreatic cancer
This trial tests a combination of chemotherapy (GnP), an immunotherapy drug (serplulimab), and targeted radiation (SBRT) as a first treatment for locally advanced pancreatic cancer that cannot be removed by surgery. The goal is to see if this triple therapy can shrink the tumor and improve outcomes.
Chengdu, SichuanAges 18–75 - NCT06190301Recruiting
Comparing injection vs. radiation for eye lymphoma
This trial compares two treatments for a slow-growing eye lymphoma called MALT lymphoma: a targeted injection (rituximab) directly into the tumor versus low-dose radiation. The goal is to see which is safer and works better, while avoiding whole-body side effects.
