Phase 1 trial to study the safety, pharmacokinetic and Preliminary Efficacy of STRO-002 in combination with Bevacizumab.


This study is a Phase 1, open-label, multicenter, dose escalation study to assess preliminary efficacy for STRO-002 combined with bevacizumab in patients with advanced ovarian cancer that is refractory or has relapsed after standard available therapy. Fallopian tube and primary peritoneal cancers are treated in the same manner as epithelial ovarian cancers and are thus included in this study.

The dosing regimen will include bevacizumab administered at the labeled dose of 15 mg/kg IV q 3 weeks given together with STRO-002 at increasing dose levels administered IV q 3 weeks. The RP2D of STRO-002 given with bevacizumab 15 mg/kg q 3 weeks will be determined by dose escalation.

Dose expansion will enroll approximately 40 subjects with advanced relapsed ovarian cancer treated with STRO-002 plus bevacizumab at the RP2D determined in dose escalation. Subjects in the dose expansion portion of the study will be required at screening to submit both archival tumor tissue (if available and available tissue has adequate tumor) and tumor tissue from a biopsy done during screening to the central laboratory for analysis of FOLRα expression, both prior to enrollment in the study.
