Dual-Target CAR-NK Cells for Recurrent or Refractory Epithelial Ovarian Cancer

Official title: A Phase 1/2, Open-Label, Dose-Escalation and Expansion Study of Dual-Target CAR-NK Cells (EB-DUALNK) Following Lymphodepleting Chemotherapy in Adults With Recurrent or Refractory Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Carcinoma

Run by Beijing Biotech · NCT07589543 · Data updated 2026-11-12

This trial tests EB-DUALNK, a dual-target CAR-NK cell therapy, in adults with recurrent or refractory epithelial ovarian, fallopian tube, or peritoneal cancer to see if it can safely help the cancer shrink or stay controlled.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-75 with recurrent or refractory epithelial ovarian, fallopian tube, or primary peritoneal carcinoma, measurable disease, and tumor tissue available for antigen assessment that meets the protocol’s dual-target positivity criteria.

Probably not a fit

Patients whose tumors do not express the selected dual targets or who experience rapid disease progression may not benefit from this therapy.

What this trial studies

This is an early-phase study that uses a biomarker-driven approach to select a dual-target CAR-NK cell therapy (EB-DUALNK) tailored to the patient's tumor antigen profile. After baseline antigen testing, the most suitable pair of targets will be chosen and EB-DUALNK will be given after lymphodepleting chemotherapy, with safety and preliminary efficacy monitored. The trial includes a dose-escalation phase to identify a recommended dose for expansion and will assess safety endpoints such as CRS and ICANS, as well as anti-tumor activity by imaging and CA-125 where appropriate. Correlative studies will examine CAR-NK persistence, cellular phenotype, cytokine profiles, and relationships between antigen expression and outcomes.

Why it matters

Potential benefit: If successful, patients may experience tumor control or delayed progression with a therapy designed to target multiple ovarian cancer antigens.

How similar studies have gone: Previous studies of CAR-NK therapies in solid tumors show potential signals of safety and efficacy, but dual-target approaches in ovarian cancer are investigational.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age 18-75 years; able to provide written informed consent.
* Histologically confirmed epithelial ovarian, fallopian tube, or primary peritoneal carcinoma that is recurrent or refractory after standard therapy (at least 2 prior systemic regimens), with measurable disease per RECIST v1.1 and ECOG performance status 0-1.
* Tumor tissue available for antigen assessment. Participant must meet protocol-defined positivity for the selected dual-target pair (example: 1 target expressed in \>=50% of tumor cells by IHC and the second target in \>=20%).
* Adequate organ function per protocol-specified labs; negative pregnancy test nd agrees to use effective contraception for a protocol-defined period after infusion.

Exclusion Criteria:

* Active CNS metastases or carcinomatous meningitis (unless treated and stable for a protocol-defined period).
* Prior gene-modified cell therapy targeting any of the study antigens (GD2, MUC1, PSMA, mesothelin) within 6 months.
* Uncontrolled active infection (including uncontrolled HIV, HBV, or HCV) or active systemic fungal infection.
* Clinically significant cardiovascular disease (e.g., recent myocardial infarction, unstable angina, uncontrolled arrhythmia) or LVEF \<50% .
* Active autoimmune disease requiring systemic immunosuppression within 14 days prior to lymphodepletion (physiologic steroid replacement permitted).
* History of organ transplantation or allogeneic hematopoietic stem cell transplantation.
* Pregnant or breastfeeding.
* Any condition that, in the investigator's judgment, would compromise participant safety or compliance.
