- Number of patients experiencing treatment-related adverse events as assessed by CTCAE v4.03 (Common Toxicity Criteria for Adverse Effects)during the study (safety and tolerability). [ Time Frame: From start of treatment to end of treatment, an expected average of 12 weeks ]Adverse events and their frequency, duration and severity, as determined based on CTCAE 4.03
- Determine the recommended phase 2 dose (RP2D) based on a combination of maximum tolerated dosed (MTD), review of adverse event data and review of AUC, Tmax and t1/2 obtained from PK data during the dose escalation phase of the study. [ 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
- Proportion of patients treated with paclitaxel and defactinib (VS-6063) with progression-free survival using Response Evaluation Criteria In Solid Tumors (RECIST), version 1.1 [ 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
- Pharmacokinetics (PK) estimates of defactinib (VS-6063) when co-administered with paclitaxel, AUC (Area Under Curve) 0-t. [ Time Frame: Time points at Day 1 and Day 15 in Cycle 1 ]Plasma concentration of defactinib (VS-6063)
- Pharmacokinetics (PK) estimates of defactinib (VS-6063) when co-administered with paclitaxel, maximum concentrations (Cmax) [ Time Frame: Time points at Day 1 and Day 15 in Cycle 1 ]Plasma concentration of defactinib (VS-6063)
- Pharmacokinetics (PK) estimates of defactinib (VS-6063) when co-administered with paclitaxel, Time to maximum concentrations (Tmax) [ Time Frame: Time points at Day 1 and Day 15 in Cycle 1 ]Plasma concentration of defactinib (VS-6063)
- Pharmacokinetics (PK) estimates of defactinib (VS-6063) when co-administered with paclitaxel, , estimates of concentration 1/2 life (T1/2) [ Time Frame: Time points at Day 1 and Day 15 in Cycle 1 ]Plasma concentration of defactinib (VS-6063)
- 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

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Able to provide signed and dated informed consent prior to initiation of any study procedures.
- Female subjects aged ≥ 18 years.
- Advanced or refractory ovarian cancer, confirmed histologically.
- Subjects may have received up to 4 prior lines of chemotherapy for their metastatic disease.

- Willing and able to participate in the trial and comply with all trial requirements.
Exclusion Criteria:
- Gastrointestinal (GI) condition which could interfere with the swallowing or absorption of study medication.
- 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.
- History of upper gastrointestinal bleeding, ulceration, or perforation within 12 months prior to the first dose of study drug.
