Engineered immune cells take aim at Hard-to-Treat cancers
NCT ID NCT04427449
First seen Jun 27, 2026 · Last updated Aug 25, 2026 · Updated 2 times
Summary
This study tests a new treatment called 4SCAR-CD44v6 T cells for people with cancers that have a specific protein called CD44v6. The therapy uses a patient's own immune cells, modified to better recognize and attack cancer cells. The trial will enroll 100 participants to check safety and see if the treatment shrinks tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 4SCAR-CD44v6 T cells (a type of immune cell therapy)
- What this could lead to
- If successful, this could offer a new treatment option for certain cancers that express the CD44v6 protein.
- What could go wrong
- This is an early phase 1/2 trial with only 100 participants, so results are preliminary. There may be side effects from the cell therapy, and it may not work for all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age older than 6 months. 2. Confirmed expression of CD44v6 in tumor specimens by immuno-histochemical staining or flow cytometry. 3. Karnofsky performance status (KPS) score is higher than 70 and life expectancy \> 3 months. 4. Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: cardiac ejection fraction ≥ 50%, oxygen saturation ≥ 90%, creatinine ≤ 2.5 × upper limit of normal, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 × upper limit of normal, total bilirubin ≤ 2.0mg/dL. 5. Hgb≥80g/L. 6. No cell separation contraindications. 7. Abilities to understand and the willingness to provide written informed consent. Exclusion Criteria: 1. Sever illness or medical condition, which would not permit the patient to be managed according to the protocol, including active uncontrolled infection. 2. Active bacterial, fungal or viral infection not controlled by adequate treatment. 3. Known HIV, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. 4. Pregnant or nursing women may not participate. 5. Use of glucocorticoid for systemic therapy within one week prior to entering the trial. 6. Receive treatment related to CD44v6 targeted therapy. 7. Patients, in the opinion of investigators, may not be able to comply with the study.
