Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.
Birmingham, AlabamaAges 18 years+ - NCT05563922RecruitingPhase 2
Testing a plan to preserve the anus after rectal chemo-radiation
This Phase 2 study tests a “total neoadjuvant” (chemo plus radiation before the main treatment) plan to see if some people with low rectal cancer can keep their anus. It may help you avoid permanent colostomy if your cancer responds well and you meet the study rules.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06965166Recruiting
Better CT scans for staging rectal cancer
This study tests a new, more detailed type of CT scan (called photon-counting CT) to see if it can better show how far rectal cancer has grown or spread. If you are already getting standard scans to stage your cancer, this study adds an extra CT scan with contrast dye to get clearer pictures.
Rochester, MinnesotaAges 18–99 - NCT05686226RecruitingPhase 2
Trial tests immune cells targeting HPV-16 cancers
This Phase 2 trial tests an immune-cell treatment (E7 TCR T cells) designed to attack cancers caused by HPV type 16. It may help people whose HPV-16+ cancer has come back or not responded to standard treatment.
Bethesda, MarylandAges 18 years+ - NCT06276686RecruitingEarly Phase 1
Exercise With Chemoradiotherapy for Locally Advanced Rectal Cancer
This study tests whether adding regular exercise during your standard chemoradiotherapy can help the treatment work better for people with locally advanced rectal cancer. It is designed for patients who have already been offered this type of therapy before surgery.
Cottingham, East YorkshireAges 18 years+ - NCT05601505RecruitingPhase 2
DNA blood test–guided treatment before rectal cancer surgery
This trial uses a special DNA blood test (circulating tumor DNA) to help guide chemotherapy and radiation before surgery for locally advanced rectal cancer. It aims to improve outcomes by tailoring treatment based on the DNA signals from the tumor.
Beijing, Beijing MunicipalityAges 18–75 - NCT06312982RecruitingPhase 2/Phase 3
Chemo, radiation, and immunotherapy before rectal cancer surgery
This trial tests whether a combination of chemotherapy, radiation, and an immunotherapy drug (tislelizumab) before surgery can improve outcomes for people with locally advanced rectal cancer that has specific protein/gene markers (pMMR or MSS). It’s designed for those who have not yet had any treatment for their cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT07372300RecruitingPhase 3
Heat therapy plus standard care for advanced rectal cancer
This trial tests whether adding modulated electro-hyperthermia (a gentle heat treatment) to standard therapy (radiation and chemotherapy) before surgery helps control locally advanced rectal cancer. It is for people whose cancer has not spread to other parts of the body.
Chiayi City, Dalin TownshipAges 20 years+ - NCT06424522Recruiting
Enema program for bowel problems after rectal cancer surgery
This trial tests a special enema program to help people with ongoing bowel problems (called LARS) after rectal cancer surgery. If standard treatments haven't worked, this program might offer a new way to manage symptoms like urgency and leakage.
Columbus, OhioAges 18 years+ - NCT05772923Recruiting
Testing rectal cancer organ-preservation after radiation
This trial compares two ways to preserve the rectum/avoid major surgery after radiation: a focused contact x-ray treatment versus waiting longer and then removing only a small area if needed. It may help some people keep more normal bowel function while still controlling the cancer.
Nijmegen, GelderlandAges 18 years+ - NCT05731726RecruitingPhase 2
New treatment before surgery for locally advanced rectal cancer
This trial tests whether giving serplulimab (an immune medicine) plus CAPEOX chemotherapy and celecoxib before surgery can shrink locally advanced rectal cancer and improve outcomes. It may help by increasing immune attack on the tumor while chemotherapy helps reduce the cancer before the operation.
Hangzhou, ZhejiangAges 18–75 - NCT05663775RecruitingPhase 2
Mesalamine to prevent bowel inflammation after melanoma immunotherapy
This study tests whether taking mesalamine can prevent colitis (bowel inflammation) in people with advanced melanoma who are treated with ipilimumab plus nivolumab. It may help reduce dangerous stomach or bowel side effects from this cancer treatment.

Common questions
- Are there clinical trials for rectal carcinoma?
- Yes. Clin2 currently lists 35 recruiting rectal carcinoma 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 rectal carcinoma 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 rectal carcinoma 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.
