What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

This trial targets 20 participants in total. It began in 2025-05-11 with a primary completion date of 2027-12-31.

Brief Summary

Screening patients who meet the criteria for peripheral blood mononuclear cell (PBMC) isolation and cell preparation. Based on the status of cell preparation and mutual agreement between the researcher and the participant, the date of reinfusion (Day 0) is determined. From Day -5 to Day -3, the participant receives a conditioning regimen with cyclophosphamide and antithymocyte globulin. After recovery for two days (Day -2 and Day -1), on Day 0, the participant receives reinfusion of BZE2203 (dose determined according to the dose-escalation requirements). The safety observation period lasts for 28 days, and clinical efficacy is assessed from Day 28 to Day 34. After comprehensive judgment, the second course of cell therapy is selected. Follow-up observations and evaluations are conducted once every three months, with follow-up visits once a year and telephone follow-ups once every two months.

Eligibility Criteria

inclusion criteria 1. Patients with gynecological solid tumors diagnosed by histopathology, with tumor tissue sample MUC1 expression rate ≥50% or MSLN expression rate ≥50%, PD-L1 positive expression, and sample source within 2 years; 2. Patients with advanced gynecological solid tumors who have failed standard treatment or are intolerant to such treatment and have no standard effective treatment options; 3. Females aged 18 to 70 years (inclusive); 4. Estimated survival time ≥ 3 months; 5. ECOG performance status score of 0 to 1 at screening and baseline; 6. Good organ and bone marrow function: 1.

Participants who have undergone other anti-tumor treatments not allowed by the protocol within 1 month before CAR-T infusion (including radiotherapy, chemotherapy, small molecules, biological treatment, or immunotherapy, other research drugs); 2. Participants who have previously received targeted therapy against MUC1 or MSLN, or cellular therapy, or any gene therapy products (including CAR-T cell therapy) or any T cell therapy at home or abroad; 3. Pregnant or breastfeeding women; 4. AIDS virus, syphilis seroreactivity positive; hepatitis B surface antigen positive, or hepatitis B core antibody positive and hepatitis B virus DNA copies higher than the detection limit or greater than or equal to 1000 copies/mL; or hepatitis C virus infection; 5. Any uncontrollable active infection, coagulopathy, or any other major disease; 6. Patients with active autoimmune diseases being treated, organ transplantation and other immune-related diseases, or long-term use of immunosuppressive drugs such as glucocorticoids: a. Glucocorticoids cannot be discontinued within 72 hours before CAR-T cell infusion; b. Immunosuppressive agents other than glucocorticoids cannot be discontinued ≥4 weeks before enrollment; 7. Patients with severe cardiopulmonary insufficiency, uncontrolled hypertension, any of the following cardiovascular disease histories within the past 6 months: III or IV heart failure defined by the New York Heart Association (NYHA), cardiac catheterization or stent, myocardial infarction, unstable angina, or other clinically significant heart disease; 8. Patients with confirmed brain metastasis, or those with a history of or current central nervous system disease, such as epileptic seizures, cerebrovascular ischemia/hemorrhage, dementia, encephalopathy, or any autoimmune disease associated with the central nervous system; 9. Patients with high risk of bleeding or perforation; 10. Patients who underwent major surgery or significant trauma within 4 weeks before single collection; 11. Patients with other malignant tumors within 3 years or concurrently (except for skin basal cell carcinoma, cervical/breast cancer in situ, etc.); 12. Any other conditions deemed unsuitable for participation in the study by the investigator.
