Treatment of advanced renal cell carcinoma using CAIX-targeted CAR-T cells

Clinical Study of CAIX-targeted CAR-T Cells in the Treatment of Advanced Renal Cell Carcinoma

Phase 1 Interventional The Affiliated Hospital of Xuzhou Medical University · NCT04969354

This study is testing a new type of immune therapy using specially designed CAR T cells to see if they can help people with advanced kidney cancer feel better and improve their treatment outcomes.

What this trial studies

This clinical study evaluates the safety and efficacy of CAR T cells that target carbonic anhydrase IX (CAIX) in patients with advanced renal cell carcinoma. The trial is divided into two phases: Phase 1 focuses on determining the maximum tolerated dose of CAR T cells after pre-treatment with chemotherapy and an anti-CAIX antibody, while Phase 2 administers the optimal dose to assess therapeutic effects. Patients will receive IL-2 injections post-infusion to enhance T cell proliferation. The study aims to provide insights into a novel immunotherapy approach for a challenging cancer.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with advanced or metastatic renal cell carcinoma who have previously undergone targeted therapies or immunotherapies.

Not a fit: Patients with active infectious diseases or those who do not meet the organ function criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new, effective immunotherapy option for patients with advanced renal cell carcinoma.

How similar studies have performed: While CAR-T cell therapies have shown promise in other cancers, this specific approach targeting CAIX in renal cell carcinoma is novel and has not been extensively tested.
