Houston, TexasAges 18 years+ - NCT06626269Recruiting
Biomarkers for immunotherapy in digestive and gynecological cancers
This study looks for new markers in the blood or tumor that could predict how well immunotherapies work for advanced digestive and gynecological cancers. It includes people getting immunotherapy, chemotherapy, or targeted therapy, and also those with certain liver or abdominal metastases that can be surgically removed after chemo.
BesançonAges 18 years+ - NCT06817161RecruitingPhase 3
Nerve stimulation for quality of life during ovarian cancer treatment

CaenAges 18 years+ - NCT07215624Recruiting
Survey on blood clot prevention after cancer surgery
This study surveys surgeons and surgical advanced practice providers about how they prevent blood clots (deep vein thrombosis) in patients after cancer surgery. It aims to understand current practices and improve future care.
Kingman, ArizonaAges 18 years+ - NCT04268121RecruitingPhase 2
Neoadjuvant chemotherapy before surgery for certain digestive neuroendocrine cancers
This study looks at whether chemotherapy given before surgery improves how long patients live without the cancer coming back. It’s aimed at people with localized, poorly differentiated digestive neuroendocrine carcinoma with a higher growth rate marker.
AmiensAges 18 years+ - NCT07594626RecruitingPhase 1/Phase 2
BMS-986504 and Pemetrexed for Advanced Tumors With MTAP Loss
This trial tests a new drug (BMS-986504) combined with an existing chemotherapy (pemetrexed) for advanced solid cancers that have a specific genetic change called MTAP deletion. The trial aims to see if this combination can slow or stop tumor growth in patients whose cancer has progressed despite prior treatment.
Chicago, IllinoisAges 18 years+ - NCT04221893Recruiting
Radiation therapy for metastatic gastrointestinal cancers
This trial tests whether adding radiation therapy to your current immunotherapy can help control cancer that has spread in the digestive system. It aims to improve symptoms and possibly slow the cancer's growth.
San Francisco, CaliforniaAges 18 years+ - NCT07283939Recruiting
Testing a tool to adjust chemo doses and reduce treatment delays
This trial tests a computer algorithm called PAGODA that helps doctors adjust chemotherapy doses for people with gastrointestinal cancers. The goal is to prevent unplanned treatment delays while keeping the treatment effective.
Fairbanks, AlaskaAges 18 years+ - NCT06380309RecruitingEarly Phase 1
Study of experimental drug IDOV-SAFE for advanced digestive cancers
This trial tests an investigational drug for people with advanced digestive system cancers (like colorectal, stomach, or liver cancer) that have stopped responding to standard treatments. The goal is to see if the drug is safe and helps control the cancer.
BeijingAges 18–75 - 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+ - NCT07421596Recruiting
Dietary supplement study for gut and digestive health
This trial tests whether a dietary supplement system can improve gut and digestive health over 8 weeks. You may be eligible if you have digestive symptoms like bloating, stomach pain, or diarrhea.
San Francisco, CaliforniaAges 18–80 - NCT06479070Recruiting
Using ctDNA to guide radiotherapy for head and neck cancer
This study looks at whether measuring a DNA fragment in the blood (called ctDNA) can help predict how well radiotherapy works for head and neck cancer. It may help doctors better tailor treatment for patients with stage III or IV disease.
Caen, CaenAges 18 years+ - NCT05956847Recruiting
Studying DNA fragments in stomach cancer tissue
This trial looks at tiny pieces of DNA found outside cells in stomach tissue to better understand how gastric (stomach) cancer starts and progresses. It may help future patients by improving how doctors study stomach cancer from biopsy and surgical samples.
Xi'an, ShaanxiAges 18–80 - NCT06353854Recruiting
Study of biomarkers in MSI-high colorectal cancer patients on immunotherapy
This trial is studying people with a specific type of advanced colorectal cancer (MSI-high/dMMR) who are starting immunotherapy with pembrolizumab. The goal is to find out which markers in the tumor might predict whether the treatment works well.
BayonneAges 18 years+ - NCT07283653Recruiting

MurciaAges 18–70 - NCT06655259RecruitingPhase 2
TURP with standard therapy for metastatic prostate cancer
This trial tests whether adding a surgery called TURP (transurethral resection of the prostate) to the usual hormone therapy and chemotherapy can help men with metastatic prostate cancer that has spread to lymph nodes, bone, or other organs. The surgery helps relieve urinary symptoms and may improve how well the cancer responds to treatment.

It focuses on colorectal cancer that is either already able to be removed or could become removable with treatment.
MadridAges 18 years+ - NCT05706779RecruitingPhase 2
Encorafenib plus cetuximab before surgery for BRAF-mutated colon cancer
This trial tests whether giving encorafenib and cetuximab before surgery can shrink or control BRAF-mutated colon or upper rectal cancer and make surgery more effective. It also checks whether this approach is safe and helps patients do better overall.

- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a digestive system cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
