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
This study evaluates the safety, tolerability, and preliminary anti-tumor activity of EB-DUALNK, a dual-target chimeric antigen receptor natural killer (CAR-NK) cell therapy, in adults with recurrent or refractory epithelial ovarian cancer. Candidates for targeting include GD2, MUC1, PSMA, and mesothelin. After baseline biomarker assessment (tumor antigen expression), the program will select the most suitable dual-target pair for clinical testing. Participants will receive lymphodepleting chemotherapy followed by EB-DUALNK infusion and safety/response follow-up.
• 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.
