About this trial

This example study evaluates locoregional allogeneic dual-target mesothelin/FAP CAR-NK cells in adults with unresectable, recurrent, or refractory pleural or peritoneal mesothelioma.

Eligible participants must have central confirmation of MSLN-positive tumor cells and FAP-positive tumorassociated stroma. The phase 1 portion defines the recommended phase 2 dose and schedule, and the phase 2 expansion explores preliminary antitumor activity, persistence, and biomarker response in pleural and peritoneal disease cohorts.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 18 to 75 years at the time of consent.

Histologically confirmed malignant pleural mesothelioma or malignant peritoneal mesothelioma; unresectable, recurrent, metastatic, or refractory disease.

Prior receipt of at least one standard systemic regimen for mesothelioma, or documented ineligibility, intolerance, or refusal of standard therapy considered reasonable by the investigator.

Central biomarker confirmation of MSLN-positive tumor cells and FAP-positive tumorassociated stroma at protocol-defined thresholds.

Disqualifiers

Active or untreated CNS metastases, leptomeningeal disease, or uncontrolled seizures.

Uncontrolled bacterial, fungal, viral, or mycobacterial infection, including empyema, active pleural space infection, peritonitis, or uncontrolled HBV, HCV, or HIV infection.

Autoimmune disease requiring systemic immunosuppression within 14 days before lymphodepletion, or prednisone equivalent greater than 10 mg/day.

Clinically significant cardiovascular disease, uncontrolled arrhythmia, unstable angina, recent myocardial infarction, or other condition judged to increase infusion risk.
