Descriptive Information

• Brief Title: Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics and Preliminary Clinical Activity of Defactinib in Combination With Avelumab in Epithelial Ovarian Cancer
• Official Title: A Phase 1/1b Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics and Preliminary Clinical Activity of Defactinib in Combination With Avelumab in Epithelial Ovarian Cancer
• Brief Summary: This is a Phase 1/1b, open-label, multicenter, dose-escalation and dose expansion trial to evaluate the safety, efficacy, PK and PD of defactinib (VS-6063) in combination with avelumab in epithelial ovarian cancer.

Detailed Description

The study is comprised of 2 sequential parts: Part A (Dose Escalation of VS-6063) and Part B (Expansion).

In Part A (Dose Escalation), approximately 18 subjects will receive avelumab IV treatment in 28-day cycles (10 mg/kg over approximately 1 hour on Days 1 and 15) and oral defactinib twice-daily (BID) continuously starting on Day 1 of Cycle 1. Subject enrollment will proceed according to a standard 3+3 design. In the absence of dose-limiting toxicity (DLT), each subject will receive the study drug regimen for a minimum of 28 days (Cycle 1) and may continue to receive additional cycles of study treatment until disease progression has been documented or unacceptable toxicity or other treatment discontinuation criteria have been met. All subjects in a cohort must have completed at least 1 cycle of dosing before dose escalation involving new subjects entered into the next dose cohort can occur. Based on the safety and PK data obtained in the dose escalation portion of the study, the RP2D of the combination will be determined.

In Part B (Expansion), approximately 80 subjects will be enrolled and will receive avelumab IV treatment in 28-day cycles (10 mg/kg over approximately 1 hour on Days 1 and 15) and oral defactinib at the RP2D dose continuously starting on Day 1 of Cycle 1.

Eligibility Criteria

Inclusion Criteria:

1. Able to provide signed and dated informed consent before initiation of any study procedures.
2. Willing and able to participate in the trial and comply with all trial requirements.
3. Female subject aged ≥ 18 years.
4. Histologically or cytologically-confirmed recurrent or resistant (progression within 6 months following the last administered platinum based therapy or progression after subsequent therapy in previously relapsed subjects), stage III-IV epithelial ovarian, fallopian tube or peritoneal cancer subjects (according to American Joint Committee on Cancer/Union for International Cancer Control TNM and International Federation of Gynecology and Obstetrics Staging System, 7th edition) whose disease has progressed following adjuvant therapy or therapy for metastatic disease.
5. Disease must be measurable with at least 1 unidimensional measurable lesion by RECIST 1.1.
6. Confirmed availability of archived FFPE tumor tissue block, or a minimum of 15 slides. If archived FFPE tissue is not available, then fresh tumor sample may be obtained in accordance with local institutional practice for tumor biopsies.

8. Predicted life expectancy of ≥ 3 months.
9. Adequate renal function with normal serum creatinine, or if creatinine above or below institutional normal range, a calculated glomerular filtration rate of ≥ 50 mL/min/1.73m2 (e.g., as calculated by the Cockcroft Gault formula) using actual body weight; if subject has body mass index > 30 kg/m2, lean body weight must be used.
10. Adequate hepatic function (total bilirubin ≤ 1.5 × upper limit of normal [ULN] for the institution; aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 × ULN.
