Testing new inhibitors for colon cancer treatment

Official title: Test of CD47-SIRPα Inhibitors on the Immune Microenvironment Colon Cancer

Run by Institut Paoli-Calmettes · NCT05955196 · Data updated 2026-11-12

This study is testing new drugs that aim to help the immune system fight colon cancer by blocking certain cells that make it harder for the body to attack tumors.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 with metastatic or non-metastatic colon cancer, or those experiencing recurrence for whom surgery is proposed.

Probably not a fit

Patients who have undergone emergency colon cancer surgery or are unable to provide consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to develop novel CD47-SIRPα inhibitors using small molecules to counteract immune suppression caused by tumor-associated macrophages in colon cancer. By employing structure-based drug design, the researchers seek to create selective and potent inhibitors that can effectively target the tumor microenvironment with reduced toxicity compared to traditional antibody therapies. The study will utilize organoids derived from patient biopsies to accurately model the immune interactions within tumors, allowing for a thorough evaluation of the immunotherapy's effectiveness.

Why it matters

Potential benefit: If successful, this approach could enhance anti-tumor immunity and improve treatment outcomes for patients with colon cancer.

How similar studies have gone: While this approach is innovative, similar studies targeting the immune microenvironment have shown promise, suggesting potential for success.
