Donor immune cells take on Hard-to-Treat cancers in early trial

NCT ID NCT05239143

First seen Nov 06, 2025 · Last updated Jun 22, 2026 · Updated 39 times

Summary

This early-phase trial is testing a new type of cell therapy called P-MUC1C-ALLO1 for people with advanced solid tumors (like breast, ovarian, lung, or pancreatic cancer) that have not responded to other treatments. The therapy uses donor immune cells engineered to recognize and attack cancer cells. The main goals are to find a safe dose and see if the treatment can shrink tumors. About 180 adults are taking part.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

P-MUC1C-ALLO1 CAR-T cells (a type of immune cell therapy made from donor cells, designed to attack cancer cells that have a protein called MUC1-C)

What this could lead to

If this works, it could point toward a new treatment option for several hard-to-treat cancers that have spread or come back.

What could go wrong

This is a very early (Phase 1) trial with only 180 people, so it is mainly checking safety and dosing. The therapy may not shrink tumors, and there could be serious side effects like cytokine release syndrome or immune reactions.

Conditions

breast cancer breast neoplasm colorectal cancer colorectal neoplasm gastric cancer gastric neoplasm head and neck squamous cell carcinoma malignant pancreatic neoplasm nasopharyngeal carcinoma, susceptibility to, 1 nasopharyngeal neoplasm non-small cell lung carcinoma ovarian cancer pancreatic neoplasm renal cell carcinoma Squamous Cell Carcinoma of Head and Neck
