- NCT03303495RecruitingPhase 3
Second-line chemo with or without bevacizumab for colon cancer
This Phase 3 study compares two treatment plans for people with metastatic colorectal cancer that got worse or caused side effects after first chemotherapy. It looks at whether adding bevacizumab (a medicine that targets blood vessels feeding tumors) improves outcomes versus using a different chemotherapy approach.
Guangzhou, GuangdongAges 18 years+ - NCT03539822RecruitingPhase 1/Phase 2
Cabozantinib and immunotherapy for advanced stomach or bowel cancers
This early-phase study tests a combination of anti-cancer pills and immune-based treatment for people with advanced stomach, esophagus, colorectal, or liver cancer. It aims to shrink tumors and see how safe the treatment is, including whether biopsy testing can help guide future care.
Westwood, KansasAges 18 years+ - NCT03551951Recruiting
Testing cancer cells and DNA in blood, urine, and bone marrow
This study looks for cancer-related cells and DNA in samples like blood, urine, and (for some) bone marrow. The goal is to see whether these tests can help detect or track solid cancers with minimal added procedures.
Columbia, MissouriAges 18 years+ - NCT03715933RecruitingPhase 1
Test drug INBRX-109 for advanced or metastatic solid tumors
This Phase 1 trial tests INBRX-109, a cancer-targeting drug, in people whose solid cancers are locally advanced or spread to other parts of the body. Because it’s Phase 1, the main goal is to see whether it’s safe and how well it can work for different tumor types that meet specific requirements.
Scottsdale, ArizonaAges 12–85 - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03740503Recruiting
Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT03748485Recruiting
Chemo after surgery for certain stage III colon cancer
This trial studies whether adding chemotherapy after surgery helps people with colon cancer that was diagnosed before surgery as stage III and later found to be without certain high-risk features. It may help lower the chance the cancer comes back, but you must meet specific surgery and health criteria.
Guangzhou, GuangdongAges 18–75 - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT03925662RecruitingPhase 3
Mebendazole added to stage 4 colon cancer care
This trial studies whether adding mebendazole (an existing anti-parasite medicine) to standard treatment can improve outcomes for people with stage 4 colon cancer. You might qualify if you have stage 4 colorectal cancer and none of the key safety concerns.
CairoAges 18 years+ - NCT03947385RecruitingPhase 1/Phase 2
First drug test for metastatic uveal melanoma with specific gene changes
This Phase 1/2 trial studies IDE196 in adults with metastatic uveal melanoma that has certain gene mutations or fusions. It’s mainly testing safety and correct dosing, and may help shrink tumors in patients matched to the tumor’s genetic changes.
Los Angeles, CaliforniaAges 18 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+ - NCT04120935Recruiting
Observational study for adults with possible or confirmed bowel cancer
This study mainly watches and records health information from adults with colorectal cancer (or a strong suspicion of it). It collects past tumor tissue and other clinical details to better understand the disease and care.
Biella, BiellaAges 18 years+ - NCT04144907Recruiting
Protein needs study for colorectal or breast cancer
This study tests how much protein people with colorectal or breast cancer need during treatment or recovery. It may help improve nutrition guidance and support for maintaining health during chemo or after surgery.
Edmonton, AlbertaAges 45–80 - NCT04190589Recruiting
Robotic right-sided colon surgery for early to mid-stage cancer
This study looks at a newer, robot-assisted surgical approach to remove part of the right colon completely when colon cancer is suspected or confirmed. It may help by aiming for more complete tumor removal while tracking safety and outcomes.
VejleAges 18 years+ - NCT04235114RecruitingPhase 1/Phase 2
PET scan test for EGFR-positive cancers using an antibody tracer
This study tests a special PET scan agent (an antibody tracer) to help doctors see EGFR-positive cancers without needing invasive procedures. It is mainly for early testing (Phase 1/2) to understand how well it works for imaging.
Saskatoon, SaskatchewanAges 18–80 - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Scottsdale, ArizonaAges 18 years+ - NCT04291755Recruiting
Stool bank for people receiving cancer immunotherapy
This study is building a “stool bank,” meaning they collect and store stool samples from people who are getting cancer immunotherapy. Researchers plan to analyze these samples to better understand cancer and treatment—your participation may help future research.
Fountain Valley, CaliforniaAges 18 years+ - NCT04339374Recruiting
Ultrasound and light imaging during rectal cancer surgery
This study tests a newer kind of imaging (ultrasound plus light-based measurements) to help doctors tell rectal cancer apart from other tissue during surgery. You may be able to take part if you’re having surgery for rectal cancer and the tumor is close enough to the anus.
St Louis, MissouriAges 19 years+ - NCT04364373Recruiting
Test of different lymph node surgery for left colon cancer
This study compares two types of lymph node removal during surgery for left-sided colon cancer. It aims to see which surgical approach may work better while ensuring you can still safely complete chemotherapy.
