Clinical Trials for Rectal Cancer

A Phase I Study of M5A-IL2 Immunocytokine Combined With Stereotactic Body Radiation Therapy (SBRT) in Patients With Metastatic Colorectal Cancer or CEA-Positive Metastatic Breast Cancer

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: This trial enrolls adults with metastatic, unresectable colorectal cancer or CEA-positive metastatic breast cancer who have failed standard therapy, testing the combination of stereotactic body radiation therapy (SBRT) and M5A-IL2 immunocytokine—a novel agent that targets CEA-expressing tumors by delivering interleukin-2 directly to the tumor microenvironment. Patients must have 1-5 metastatic lesions amenable to SBRT and good performance status; CNS metastases and significant comorbidities are excluded.

ClinicalTrials.gov ID: NCT06130826

Sequential Combined TAS-102 and Oxaliplatin Alternating With TAS-102 and Irinotecan (Sequential TASOXIRI) With Bevacizumab for Late-Line Metastatic Colorectal Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with metastatic colorectal cancer who have progressed after standard chemotherapies (including 5-FU, oxaliplatin, irinotecan, and appropriate antibody therapies), evaluating a sequential regimen of TAS-102 (nucleoside metabolic inhibitor) alternating with oxaliplatin and irinotecan plus bevacizumab. Patients must not have had prior TAS-102 exposure and should have good performance status and organ function.

ClinicalTrials.gov ID: NCT05806931

A Randomized Phase III Study of Systemic Therapy With or Without Hepatic Arterial Infusion for Unresectable Colorectal Liver Metastases: The PUMP Trial

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: Adults with unresectable, liver-only metastatic colorectal cancer (after 3–6 months of first-line chemotherapy, ECOG 0-1, no significant extrahepatic disease) are randomized to standard systemic chemotherapy (e.g., FOLFOX, FOLFIRI, or OX/IRI ± targeted agents) with or without hepatic arterial infusion of floxuridine, an antimetabolite delivered directly to the liver via an implanted pump.

ClinicalTrials.gov ID: NCT05863195

Phase II Study Evaluating the Efficacy of PDS01ADC in Combination With Hepatic Artery Infusion Pump (HAIP) and Systemic Therapy for Subjects With Metastatic Colorectal Cancer, Intrahepatic Cholangiocarcinoma, or Metastatic Adrenocortical Carcinoma

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

No known activity

No investigational drug(s) in this trial have shown anticancer activity yet in clinical trials

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: Adults with unresectable, liver-dominant colorectal metastases, intrahepatic cholangiocarcinoma, or metastatic adrenocortical carcinoma after at least one prior systemic chemotherapy regimen receive hepatic artery infusion of floxuridine plus dexamethasone and disease-appropriate systemic chemotherapy. They also receive PDS01ADC, an investigational antibody–IL-12 fusion designed to bind exposed DNA in necrotic tumor tissue and stimulate local antitumor immunity.

ClinicalTrials.gov ID: NCT05286814

A Phase 1 Study of 5-Fluorouracil in Combination With Abemaciclib in Metastatic, Refractory CRC

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: This trial enrolls adults with microsatellite stable (MSS) metastatic colorectal cancer refractory to standard therapies, testing the combination of oral abemaciclib (a selective CDK4/6 inhibitor that blocks cell cycle progression) with intravenous 5-fluorouracil. Prior CDK4/6 inhibitor use and intolerance to fluoropyrimidines are exclusion criteria.

ClinicalTrials.gov ID: NCT06654037

Phase I Trial of 5-Fluorouracil (5FU) -Based Therapy in Combination With Hydroxytyrosol (HT) in Patients With Advanced or Metastatic Colorectal Cancer

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: This study enrolls adults with advanced or metastatic colorectal cancer (excluding dMMR/MSI-H) who are candidates for first-line 5-FU-based chemotherapy (FOLFIRI or FOLFOX ± biologics), testing the addition of oral hydroxytyrosol—a polyphenol with preclinical anti-inflammatory and immune modulatory effects—to standard treatment. Eligibility requires ECOG 0–1, measurable disease, and adequate organ function.

ClinicalTrials.gov ID: NCT06833866

Phase II Study of Hypofractionated Radiation Therapy to Augment Immune Response in Patients With Metastatic GastroIntestinal Malignancies Progressing on Immune Therapy (ARM-GI)

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with metastatic gastrointestinal cancers (including esophageal, gastric, small intestine, hepatocellular, pancreaticobiliary, colorectal, or anal) who are progressing on a checkpoint or CTLA-4 inhibitor, treating them with hypofractionated external beam radiation (30 Gy in 5 fractions to 1-5 lesions) in addition to ongoing immunotherapy. The aim is to determine if radiation can enhance systemic immune response and improve outcomes in this refractory population.

ClinicalTrials.gov ID: NCT04221893

A Phase I Study of Intraperitoneal 5FU+Oxaliplatin in Patients with Colorectal Cancer with Isolated Peritoneal Metastasis

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: This trial enrolls adults with biopsy-proven colorectal cancer and isolated peritoneal metastases (PCI >20), without prior cytoreductive surgery, who receive intraperitoneal oxaliplatin and 5FU via a peritoneal port. It is designed to assess safety, tolerability, and dose parameters of this locoregional chemotherapy approach.
