Recruiting studies
- NCT05463796Recruiting
Prevention and early detection for people at high cancer risk
This study looks at surveillance (watching closely), prevention, and early “interception” steps to lower the chance that cancer will develop or be found later. It is for people with genetic risk, past cancer treatment exposures, strong family history, or certain early pre-cancer or high-risk conditions.
Boston, MassachusettsAges Any age - NCT05448547RecruitingPhase 3
Tested curative vs conservative treatment for older men with high-risk prostate cancer
This Phase 3 study compares an immediate curative treatment plan versus a more conservative approach in men age 75 and older with newly diagnosed, high-risk prostate cancer. The goal is to see which strategy controls the cancer while better protecting quality of life.
CopenhagenAges 75 years+ - NCT05313815Recruiting
Test a stronger prostate radiation boost for high-risk prostate cancer
This trial studies whether giving a moderate “boost” dose of radiation to the prostate—along with radiation to the pelvic area—can better control high-risk localized prostate cancer. You may benefit if you have high-risk disease and can safely receive radiation.
Toronto, OntarioAges 18 years+ - NCT05179889RecruitingPhase 2/Phase 3
Chemo after surgery for high-risk stage III colon cancer
This trial tests giving mFOLFIRINOX chemotherapy after curative surgery for people with high-risk stage III colon cancer. It aims to lower the chance that cancer comes back.
DaejeonAges 20–75 - NCT04947254RecruitingPhase 2
Add niraparib to hormone therapy after prostate radiation
This Phase 2 trial tests whether adding niraparib to standard hormone therapy (androgen ablation) after radiation works better for men with high-risk, localized or locally advanced prostate cancer. It may help control the cancer for longer, while also collecting extra tissue and blood to study why the treatment works or doesn’t.
Houston, TexasAges 18 years+ - NCT04947098Recruiting
Preventing cancer in adults
This trial looks at ways to help prevent cancer in adults. It may be helpful if you’re interested in cancer prevention and meet the basic age requirements.
Greenville, South CarolinaAges 18 years+ - NCT04891068RecruitingPhase 2
Pre-surgery low-dose azacitidine for high-risk early breast cancer
This trial studies whether giving a low dose of azacitidine before surgery can shrink or control high-risk early breast cancer. It’s meant for adults whose cancer has not yet spread to distant organs.
Chicago, IllinoisAges 18 years+ - NCT04824053Recruiting
Dairy products study for people at high risk of colon cancer
This trial studies whether specific dairy products (UNICLA-A2) can help lower the risk of future colon problems in people considered high risk for colorectal cancer. You may be asked to keep using dairy consistently and undergo colon checks as part of usual follow-up.
Zaragoza, ZaragozaAges 18–80 - NCT04725903Recruiting
Proton beam radiation for high-risk prostate cancer
This trial tests proton radiation therapy for people with high-risk prostate cancer. It may help by delivering radiation in a more targeted way, with the goal of controlling the cancer while reducing exposure to nearby healthy tissue.
Atlanta, GeorgiaAges 18 years+ - NCT04525989Recruiting
Short-course proton vs photon radiation before rectal surgery
This study compares two types of pre-surgery radiation—protons versus standard photons—in people with high-risk rectal cancer. The goal is to shrink and control the tumor while safely getting you ready for surgery, and to see which approach works better.
Stockholm, SolnaAges 18 years+ - NCT04402151RecruitingPhase 2
PSMA scan–guided targeted radiation for higher-risk prostate cancer
This trial uses a special PET/MR scan to help doctors aim stereotactic radiation more precisely for certain higher-risk or unfavorable intermediate prostate cancers. It studies whether this targeted approach can safely treat the prostate (and specific areas needing extra treatment) without spreading to the body.
New York, New YorkAges 21–90 - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT04215731RecruitingPhase 3
Chemo plus targeted drug before surgery for high-risk rectal cancer
This trial tests giving chemotherapy (mFOLFOXIRI) plus bevacizumab before surgery for rectal cancer that has higher-risk features. It aims to shrink or control the cancer early to improve outcomes after treatment.
Guangzhou, GuangdongAges 18–70 - NCT04047641RecruitingPhase 1/Phase 2
Quizartinib with chemotherapy for new or returning leukemia
This trial tests a combination of anti-leukemia drugs (including quizartinib) together with chemotherapy for people with acute myeloid leukemia (AML), a rare mixed-type leukemia, or high-risk myelodysplastic syndrome (MDS). It may help by trying to better control cancer in people whose disease is newly diagnosed or has returned/not responded to prior treatment.
Houston, TexasAges 18 years+ - NCT00801489RecruitingPhase 2
New treatment for AML or high-risk MDS using combination chemo
This trial tests a combination treatment (chemo drugs plus a growth-factor medicine) for people newly diagnosed with acute myeloid leukemia (AML) or certain high-risk myelodysplastic syndromes (MDS). It may help by targeting cancer cells in the blood and bone marrow and improving remission chances.
Houston, TexasAges 18 years+ - NCT03280511RecruitingPhase 2
After surgery chemo sprayed into the abdomen for high-risk colon cancer
This Phase 2 study tests whether spraying chemotherapy into the abdomen (through a small procedure) after colon cancer surgery can lower the chance the cancer comes back. It is meant for people with high-risk tumor features but who have had surgery and have no proven relapse yet.
OdenseAges 18 years+ - NCT07748325RecruitingPhase 2
Checking if immunotherapy after surgery helps prevent lung cancer return
This trial is for people with non-small cell lung cancer who have already had immunotherapy and chemotherapy before surgery, followed by complete removal of the tumor. It tests whether continuing immunotherapy after surgery (adjuvant treatment) can lower the risk of cancer coming back compared to just watching and waiting.
Chengdu, SichuanAges 18–75 - NCT07508982RecruitingPhase 1/Phase 2
Combination therapy for high-risk acute myeloid leukemia
