Immune cells take on ovarian cancer in early trial
NCT ID NCT03362606
First seen Jun 27, 2026 · Last updated Aug 25, 2026 · Updated 2 times
Summary
This early-phase trial is testing whether specially engineered immune cells (OC-CTLs) can safely fight ovarian cancer. Twenty women with advanced-stage disease will receive 2 to 4 infusions of these cells. Researchers will monitor side effects and check if tumors shrink or stabilize.
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 (OC-CTLs)
- What this could lead to
- If it works, this could point toward a new immune-based treatment for advanced ovarian cancer.
- What could go wrong
- This is a very early, small trial (20 people) focused on safety. The treatment may not shrink tumors or could cause side effects like fever or cytokine reactions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Written, informed consent obtained prior to any study-specific procedures. 2. Age older than 10 years. 3. Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1. 4. Expected survival ≥ 12 weeks. 5. Histologically confirmed and documented high risk International Federation of Gynecology and Obstetrics (FIGO): Stage II-IV. 6. Not pregnant, and on appropriate birth control if of childbearing potential. 7. Initial hematopoietic reconstitution with * neutrophils (ANC) ≥ 1,000/mm\^3; * platelet (PLT) ≥ 100,000/mm\^3. 8. Proper renal and hepatic functions (ULN denotes "upper limit of normal range") with * serum creatinine ≤ 2×ULN; * serum bilirubin ≤ 2×ULN; * AST/ALT ≤ 2×ULN; * ALKP ≤ 5×ULN; * serum bilirubin. 2.0 is acceptable in the setting of known Gilbert's syndrome. 9. Human immunodeficiency virus (HIV) and Hepatitis C virus (HCV) test were negative. Exclusion Criteria: 1. Patients with ovarian tumors with low malignant potential (i.e. borderline tumors); 2. Patients with evidence of abdominal free air not explained by paracentesis or recent surgical procedure (prior, current or planned treatment). 3. Previous treatment of adoptive T cell therapy. 4. Current or recent treatment (within the 28-day period prior to Day 0) with another investigational drug 5. Minor surgical procedures within 2 days prior to Day 0 (including central venous access device placement for chemotherapy administration, tumor biopsies, needle aspirations). 6.
