Genetically modified T cells for ovarian cancer

Innovative Treatment of Ovarian Cancer Based on Immunogene-modified T Cells (IgT)

Phase1; Phase2 Interventional Shenzhen Geno-Immune Medical Institute · NCT03184753

This test tries infusions of a patient's own genetically modified T cells (OC-IgT) given into the bloodstream or directly into tumors to see if they are safe and help women with advanced ovarian cancer.

What this trial studies

This phase 1/2 study uses autologous OC-IgT cells — a patient's own T cells engineered to target ovarian cancer — delivered by intravenous infusion or by direct injection into tumors. The primary endpoints focus on safety and tolerability of the infusions, while secondary endpoints include the success rate of manufacturing OC-IgT cells and measures of anti-tumor activity. Eligible participants are women aged 20 or older with high-risk epithelial ovarian cancer (FIGO stage III–IV), adequate organ function, and ECOG performance status 0–2. All treatment and follow-up are conducted at Shenzhen Geno-Immune Medical Institute, with close monitoring for immune-related and infusion-related toxicities.

Who should consider this trial

Good fit: Women aged 20 or older with histologically confirmed high-risk epithelial ovarian cancer (FIGO stage III–IV), ECOG 0–2, adequate blood, liver and kidney function, life expectancy ≥3 months, and the ability to undergo leukapheresis and travel to Shenzhen are ideal candidates.

Not a fit: Patients with non-epithelial ovarian tumors, inadequate organ function or blood counts, active pregnancy, poor performance status, or those who cannot provide sufficient T cells for manufacturing may not benefit from this therapy.

Why it matters

Potential benefit: If successful, OC-IgT therapy could offer a targeted immunotherapy that reduces tumor burden or extends remission for women with advanced ovarian cancer.

How similar studies have performed: CAR-T therapies have produced dramatic results in blood cancers but have shown limited and mixed success in solid tumors like ovarian cancer, so this approach remains experimental.
