CBX-12 - 125mg/m2 q21d

125mg/m2 CBX-12 administered by intravenous (IV) infusion every 21 days. Treatment will continue until there is evidence of progressive disease (PD) or development of unacceptable toxicity.

Group Type EXPERIMENTAL

* 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.

* Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
* Adequate liver, renal, hematologic, pulmonary and coagulation function.

Exclusion Criteria

* Cytotoxic chemotherapy, biologic agent, investigational agent, or radiation therapy within 3 weeks prior to the first dose of CBX-12.
* Subjects who are currently receiving any other anticancer or investigational agent(s).
* Clinically significant intercurrent disease.
* Active human immunodeficiency virus (HIV) infection.
* Active hepatitis B or C infection.
