Sequential CD146 and GPC3 CAR-T Cell Therapy in Advanced Ovarian Cancer

Prior Therapy: Previous treatment with any CAR-T cell therapy or other gene-engineered T-cell therapy targeting CD146 or GPC3. (Patients who received prior immunotherapies such as checkpoint inhibitors are allowed if a washout period is met, but prior CAR-T could confound results or pose increased risk.)

CNS Involvement: Active central nervous system (CNS) metastases or carcinomatous meningitis. (Patients with a history of CNS metastases that have been effectively treated and are radiographically stable off steroids may be eligible, per protocol specifics.)

Comorbid Illness: Uncontrolled intercurrent illness including, but not limited to, active uncontrolled infection, clinically significant heart failure (e.g. NYHA Class III-IV), unstable angina or arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. (Patients with controlled chronic conditions may be eligible at the investigator's discretion.)

Immunosuppression: Active hepatitis B or C infection with viremia, or known HIV infection with uncontrolled viral load. Patients requiring chronic systemic immunosuppressive therapy (e.g. for an autoimmune condition or organ transplant) are excluded, except for physiologic dose steroids.
