New hope for tough ovarian cancer: CBX-12 trial launches
NCT ID NCT06315491
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study tests a new drug, CBX-12, in 40 women with ovarian cancer that has stopped responding to platinum-based chemotherapy. The goal is to see if CBX-12 can shrink tumors and how safe it is at two different dose levels given every three weeks. Participants must have a specific type of ovarian, fallopian tube, or primary peritoneal cancer that is resistant or refractory to prior treatment.

Inclusion Criteria: * Subjects must have histologically- or cytologically-diagnosed epithelial high-grade serous cancer of the ovary, fallopian tube cancer or primary peritoneum cancer that is refractory to prior therapy and must have platinum-resistant disease defined as: * Subjects who have received only 1 platinum-based chemotherapy regimen for at least 4 cycles of platinum must have disease progression on treatment or occurring ≤ 26 weeks after their last dose of platinum. * Patients who have progressed following a second course of a platinum based regimen. * Subjects may have up to 2 additional systemic regimens for advanced or metastatic disease. Maintenance regimens (e.g., with a PARP inhibitor or bevacizumab) are not considered separate regimens. * Age greater than or equal to 18 years at the time of signing the informed consent form (ICF). * Has measurable disease per RECIST 1.1. * Has provided written informed consent. * Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1. * Adequate liver, renal, hematologic, pulmonary and coagulation function.
