This is a Phase I/Ib, open-label, multicenter, dose-escalation trial of paclitaxel in combination with defactinib (VS-6063), a focal adhesion kinase inhibitor, in patients with advanced ovarian cancer. This clinical study is comprised of 2 parts: Phase I (Dose Escalation) and Phase Ib (Expansion). The purpose of this study is to assess assess the safety (including the recommended phase 2 dose), the pharmacokinetics, and the anti-cancer activity of defactinib (VS-6063) when administered in combination with paclitaxel. Pharmacodynamic effects will also be examined in tumor biopsies.

Primary Outcome Measures:
  • Assess the safety and tolerability of defactinib (VS-6063) when administered in combination with paclitaxel in subjects with advanced ovarian tumors [ Time Frame: From start of treatment to end of treatment, an expected average of 12 weeks ]
    Adverse events and their frequency, duration and severity, physical examination, laboratory parameters, vital signs and ECG change monitoring as determined based on CTCAE (Common Toxicity Criteria for Adverse Effects) 4.03

  • Establish the recommended phase 2 dose (RP2D) of defactinib (VS-6063) in combination with paclitaxel in subjects with advanced ovarian tumors [ Time Frame: From start of treatment to end of cycle 1 (4 week cycles) ]
    The RP2D will be determined based on the maximum tolerated dose (MTD) of defactinib (VS-6063) in combination with paclitaxel as determined by number of participants with dose limiting toxicities (DLTs) related to defactinib in combination with paclitaxel

Secondary Outcome Measures:
  • Evaluate the efficacy of subjects treated with paclitaxel and defactinib (VS-6063) [ Time Frame: Every 2 cycles up to end of treatment, an expected average of 12 weeks ]
    Response rate and progression-free survival, as determined by Response Evaluation Criteria In Solid Tumors (RECIST), version 1.1

  • Assess the pharmacokinetics (PK) of defactinib (VS-6063) when co-administered with paclitaxel [ Time Frame: Time points at Day 1 and Day 15 in Cycle 1 ]
    PK parameters, including but not limited to plasma concentration, AUC (Area Under Curve) 0-t, Cmax, Tmax, and T1/2

Other Outcome Measures:
  • Evaluate biomarkers of defactinib (VS-6063) activity [ Time Frame: Day 1 and Day 10 of treatment ]
    Pre and post dose biomarkers (including but not limited to FAK and phospho-FAK, as well as specific markers for cell cycle inhibition, apoptosis and cancer stem cells) in archival tumor tissue and new biopsy samples

  • Examine if the tumor expression status correlates with response to defactinib (VS-6063) therapy [ Time Frame: From start of treatment to end of treatment, an expected average of 12 weeks ]
    Tumor expression status (pFAK and other biomarkers) compared with response to defactinib, as determined by Response Evaluation Criteria In Solid Tumors (RECIST), version 1.1

Estimated Enrollment: 27
Study Start Date: January 2013
Estimated Study Completion Date: January 2016
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Oral defactinib (VS-6063) administered twice daily, in combination with intravenous paclitaxel administered on Days 1, 8, and 15 of a 28 day cycle.
Drug: defactinib (VS-6063) Drug: Paclitaxel
Other Name: Taxol

Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Able to provide signed and dated informed consent prior to initiation of any study procedures.
  2. Female subjects aged ≥ 18 years.
  3. Advanced or refractory ovarian cancer, confirmed histologically.
  4. Subjects may have received up to 4 prior lines of chemotherapy for their metastatic disease.
  5. All persistent clinically significant toxicities from prior chemotherapy must be ≤ Grade 1.
  6. ECOG performance status of 0 or 1 (refer to Appendix A), measured within 72 hours before the start of treatment.
  7. Predicted life expectancy of ≥ 3 months.
  8. Adequate renal function [creatinine ≤ 1.5x ULN (upper limit of normal)] or GFR of ≥ 50mL/min.
  9. Adequate hepatic function (total bilirubin ≤ 1.5x ULN for the institution; AST [aspartate transaminase] and ALT [alanine transaminase] ≤ 3x ULN, or ≤ 5x ULN if due to liver involvement by tumor).
  10. Adequate bone marrow function (hemoglobin ≥ 9.0 g/dL; platelets≥ 100 x109cells/L; absolute neutrophil count ≥ 1.5x109 cells/L).
  11. Corrected QT interval (QTc) < 470 ms (as calculated by the Fridericia correction formula).
  12. Negative pregnancy test for females of child-bearing potential; must be surgically sterile, postmenopausal, or willing and able to be compliant with a contraceptive regimen (double barrier birth control) during and for 3 months after the treatment period.
  13. Willing and able to participate in the trial and comply with all trial requirements.

Exclusion Criteria:

  1. Gastrointestinal (GI) condition which could interfere with the swallowing or absorption of study medication.
  2. Uncontrolled or severe concurrent medical condition (including uncontrolled brain metastases). Stable brain metastases either treated or being treated with a stable dose of steroids/anticonvulsants, with no dose change within 28 days prior to the first dose of study drug, will be allowed.
