Recruiting studies
- NCT03998202Recruiting
Study of chemotherapy side effects in older colorectal cancer patients
This study looks at how chemotherapy and immunotherapy affect the body in older adults with colorectal cancer, especially early side effects. It may help researchers understand why some people lose strength and how to better predict and manage treatment toxicity.
Millville, DelawareAges 60 years+ - NCT06580002RecruitingPhase 2
Can Riluzole Help with Chemo Brain? A Pilot Study
This study tests if a medicine called riluzole (currently used for ALS) can help with 'chemo brain' – memory and thinking problems after cancer treatment. It is for people who feel their mental sharpness has declined after breast cancer therapy, certain chemotherapies, or brain radiation.
Orange, CaliforniaAges 18 years+ - NCT04050345Recruiting
Blood test to spot DNA changes after early colon cancer surgery
This study checks a “cell-free tumor DNA” blood test to see if cancer mutations can predict relapse after surgery for early colorectal cancer. If results look risky, they may help guide closer follow-up and future treatment decisions.
Milton Keynes, BuckinghamshireAges 18 years+ - NCT04074538Recruiting
Colorectal cancer study to help researchers learn patterns
This study is collecting information from people with newly diagnosed colon or rectal cancer, to better understand the disease and support future research. It may help you and others by improving how colorectal cancer is studied and potentially treated over time.
Hangzhou, ZhejiangAges 18 years+ - NCT04185779Recruiting
Colorectal cancer screening colonoscopy study
This study looks at patterns of colorectal (colon and rectum) findings in people who are having a colonoscopy as part of routine care. It may help improve how doctors detect and understand colorectal cancer and related growths over time.
South Shields, Tyne and WearAges 18 years+ - NCT04221893Recruiting
Radiation for tumors that keep growing despite immunotherapy
This study tests whether targeted radiation can help people with metastatic gastrointestinal cancers whose cancer is still getting worse on immunotherapy. It focuses on treating a small number of spots that are progressing while keeping other spots that are safer to leave alone.
San Francisco, CaliforniaAges 18 years+ - NCT04329494RecruitingPhase 1
Study of targeted drug delivery into the abdomen using PIPAC
This Phase 1 trial tests PIPAC, a way to deliver anti-cancer medicine directly into the abdomen using a minimally invasive procedure. It is for people with peritoneal spread from certain cancers to see whether this approach is safe and potentially helpful.
Duarte, CaliforniaAges 18 years+ - NCT04489238Recruiting
Study of young and average-age colorectal cancer causes
This research collects health information (and for some groups, stool samples) to better understand why colorectal cancer happens in different age groups. If you fit the age and diagnosis criteria, your participation could help researchers find patterns that may improve future care.
Basking Ridge, New JerseyAges 18 years+ - NCT04490733Recruiting
Test dual-task walking to improve thinking in colorectal cancer
This study looks at a walking exercise that makes you do two tasks at once (for example, walking while focusing on something) to see if it can improve thinking and memory. It is for people newly diagnosed with early to mid-stage colorectal cancer, and excludes people with other cancers or cancer coming back.
TaipeiAges 40–75 - NCT04511039RecruitingPhase 1
New targeted pill combo for advanced colon or stomach cancers
This Phase 1 trial tests a combination of oral (swallowed) drugs—trifluridine/tipiracil plus talazoparib—in people with advanced (locally advanced or metastatic) colorectal or gastroesophageal adenocarcinoma. It’s designed to see how well the treatment can control cancer and to better understand side effects and dosing.
Buffalo, New YorkAges 18 years+ - NCT04516681RecruitingPhase 3
Ascorbic acid plus immunotherapy for spread colorectal cancer
This trial tests whether intravenous vitamin C (ascorbic acid) combined with an immune treatment (adebrelimab) can slow or shrink metastatic colorectal cancer that can’t be removed with surgery. It focuses on tumors that strongly show a specific marker called GLUT3, and aims to see if the combination works better than standard approaches.
Shanhai, Shanghai MunicipalityAges 18–75 - NCT04527861Recruiting
Minimally invasive single-incision surgery for colon cancer
This trial compares a single-incision laparoscopic operation versus the usual laparoscopic operation for colorectal (colon or “high rectum”) cancer. It looks at cancer outcomes and may help determine which approach is safer and works better for the right patients.
Lanzhou, GansuAges 18–85 - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Irvine, CaliforniaAges 12 years+ - NCT04624555Recruiting
Check how well stool DNA tests help watch for colon cancer return
This trial studies whether an at-home stool DNA test (Mt-sDNA) can safely and usefully monitor people after colon or rectal cancer treatment. It’s mainly about whether the test is practical and helpful during routine follow-up.
Cleveland, OhioAges 18 years+ - NCT04680260RecruitingPhase 2
Personalized follow-up after limited surgery or radiation for colon cancer
This Phase 2 study tests the best way to choose and then follow treatment when colorectal cancer has spread only to a small number of spots. You may be eligible if your doctors can remove or precisely treat the spots and there’s no sign of additional spread on scans.
Aarhus NAges 18 years+ - NCT04693377Recruiting
Freezing tumor treatment plus targeted radiation for painful bone spread
This study tests whether combining a “freezing” procedure (cryoablation) with focused external radiation (SBRT) can reduce pain from bone metastases. It’s for people with certain cancers that have spread to bone and are having significant pain in a specific bone spot.
Houston, TexasAges 18 years+ - NCT04739072Recruiting
Check colorectal cancer blood tests after curative treatment
This study measures “minimal residual disease,” meaning tiny amounts of cancer that may remain after surgery, using blood samples. It may help doctors better detect who is at higher risk of cancer coming back and guide follow-up care.
Gilbert, ArizonaAges 18 years+ - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04812912Recruiting
Study sexual and reproductive effects in early colon cancer
This study looks at how early-onset colorectal cancer treatment affects reproductive and sexual health over time. It asks eligible people to complete questionnaires so researchers can understand and possibly improve care during and after treatment.
