AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Birmingham, AlabamaAges Any age - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT05239546RecruitingPhase 2
Dostarlimab before colon surgery for mismatch-repair–deficient cancer
This study tests dostarlimab given before surgery for stage II or III colon cancer that has a specific DNA repair defect. It aims to shrink or control the cancer so that some people may be able to skip surgery if the results are good.
Iowa City, IowaAges 18 years+ - NCT05770102RecruitingPhase 2/Phase 3
Atezolizumab for cancers with high mutation or immune markers
This trial tests atezolizumab, a cancer immunotherapy, for people whose tumors have high mutation levels (TMB), or are “MSI-high,” or have CMMRD. It may help shrink cancer or slow its growth by boosting the immune system’s ability to recognize the tumor.
BelfastAges Any age - NCT05795244RecruitingPhase 2
Nivolumab for resected mismatch-repair deficient endometrial cancer
This trial studies nivolumab (an immune therapy that helps your body recognize cancer) after surgery for endometrial cancer that has mismatch-repair deficiency (MMR-d) or high microsatellite instability (MSI-H). It aims to lower the chance the cancer comes back by treating “leftover risk” after the tumor is removed.
SeoulAges 20 years+ - NCT06362369RecruitingPhase 1/Phase 2
Oral 7HP349 with immunotherapy for advanced solid tumors
This trial tests an experimental oral drug (7HP349) combined with two immunotherapy drugs (ipilimumab and nivolumab) for people with advanced solid tumors. It aims to see if the combination is safe and effective in shrinking tumors.
Aurora, ColoradoAges 18 years+ - NCT06903858RecruitingPhase 2
Toripalimab plus celecoxib for dMMR/MSI-H colorectal cancer
This trial tests whether combining toripalimab (an immunotherapy) with celecoxib (an anti-inflammatory drug) can shrink locally advanced colorectal tumors that have specific genetic features (dMMR or MSI-H). It aims to help people who haven't had any prior treatment for their colorectal cancer.

Common questions
- Are there clinical trials for mismatch repair deficiency?
- Yes. Clin2 currently lists 25 recruiting mismatch repair deficiency studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a mismatch repair deficiency trial?
- 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 mismatch repair deficiency 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.
