Supercharged immune cells take on tough gynecologic cancers
NCT ID NCT05468307
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested a new therapy called GC203 TIL in 26 people with advanced gynecologic tumors that had stopped responding to standard treatments. Doctors took immune cells from each patient's tumor, genetically modified them to be more powerful, and infused them back. The main goals were to check safety and see if the treatment could shrink tumors or slow disease progression.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- engineered immune cells (GC203 TIL)
- What this could lead to
- If it works, this could point toward a new treatment option for advanced gynecologic tumors that have not responded to standard therapies.
- What could go wrong
- This is a very early, small study (26 people) focused on safety. The treatment may not shrink tumors or could cause serious side effects. Results may not apply to all patients.

Hematology and Chemistry(within 7 days prior to enrollment): * Absolute count of white blood cells≥2.5×10\^9/L; * Absolute count of neutropils≥1.5×10\^9/L; * Absolute count of lymphocytes ≥0.7×109/L; * Platelet count≥100×10\^9; * hemoglobin≥90 g/L; * Activated partial thromboplastin time (APTT) ≤1.5xULN (Unless received anticoagulant therapy within the previous 3 days); * International normalized ratio (INR) ≤1.5xULN (Unless received anticoagulant therapy within the previous 3 days); * Serum creatinine ≤1.5mg/dL(or ≤132.6μmol/L), or clearance rate≥50mL/min; * Serum ALT/AST ≤3×ULN(subjects with liver metastasis ≤3×ULN); * Totol bilirubin≤1.5×ULN; 9. no absolute or relative contraindications to operation or biopsy; 10. Test subjects with child-bearing potential must be willing to practice approved highly effective methods of contraception at the time of informed consent, and continue within 1 year after the completion of lymphodepletion; 11. Any malignant tumor-targeting therapies, including radiotherapy, chemotherapy and biologics must cease 28 days before obtaining TILs; 12. Be able to understand and sign the informed consent document; 13. Be able to stick to follow-up visit plan and other requirements in the agreement. Exclusion Criteria: 1. Need glucocorticoid treatment, and daily dose of Prednisone greater than 15mg (or equivalent doses of hormones) or outoimmune diseases requiring immunomodulatory treatment; 2. Forced expiratory volume in one second (FEV1) less than 2L, diffusing capacity of the lung for carbon monoxide (DLCO) (calibrated) less than 40%; 3. Significant cardiovascular anomalies according to any of the following definition: New York Heart Association (NYHA) Grade III or IV congestive heart failure, clinically significant low blood pressure, uncontrollable symptomatic coronary artery diseases, or ejection fraction less than 35%; Severe cardiac rhythm and conduction anomaly, such as ventricular arrhythmia requiring clinical intervention, second-third degree atrio-ventricular conductive block, etc. 4. Human immunodeficiency virus (HIV) infection or anti-HIV antibody positive, active HBV or HCV infection (HBsAg positive and/or anti-HCV positive), syphilis infection or Treponema pallidum antibody positive; 5. Severe physical or mental diseases; 6. Have a systemic active infection requiring treatment, or have positive blood cultures(or imaging evidence of infection); 7.

Previous anti-tumor treatment AE did not return to CTCAE5.0 version grade 1 or below (toxicity considered by the investigator as non-safety concerns like alopecia excluded); 11. Females in pregnancy or lactation; 12. History of organ transplantation, allogeneic stem cell transplantation, and renal replacement therapy; 13. Researchers considering the test subject as having a history of other severe systemic diseases, or other reasons inappropriate for the clinical study.
