Can a Patient's own immune cells be engineered to fight a rare sarcoma?
NCT ID NCT07104682
First seen Aug 04, 2026 · Last updated Aug 05, 2026 · Updated 1 time
Summary
This trial tests a personalized cell therapy called GCAR1 in a single patient with metastatic alveolar soft part sarcoma (ASPS) that has relapsed and cannot be surgically removed. The therapy uses the patient's own immune cells, engineered to recognize and attack cancer cells displaying a specific protein. The goal is to see if this treatment is safe and can shrink or control the cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GCAR1, a personalized cell therapy made from the patient's own immune cells (T-cells) engineered to recognize and attack cancer cells that carry a protein called GPNMB.
- What this could lead to
- If successful, this approach could offer a new treatment option for alveolar soft part sarcoma, a rare cancer with limited therapies.
- What could go wrong
- This is an early, single-patient study, so results may not apply to others. CAR T-cell therapy can cause severe side effects, and the treatment may not shrink the tumor.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * The patient must have relapsed ASPS that is in the opinion of the treating physician not resectable, or that resection would be associated with significant morbidity. * The patient must provide informed consent. * The only other eligibility criteria is adequate organ function, defined as creatinine clearance \>30 ml/min and LVEF \>45%. Exclusion Criteria: * Any active uncontrolled infection * Any anti-cancer therapy within 21 calendar days prior to the first dose of lymphodepleting chemotherapy
