Phase I Dose Escalation Study of VS-4718 in Subjects With Metastatic Non-Hematologic Malignancies

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01849744

Brief Summary:
This is a Phase I, open-label, multicenter, dose-escalation trial of VS-4718, a focal adhesion kinase inhibitor, in subjects with metastatic non-hematologic malignancies. This clinical study is comprised of 2 parts: Part 1 (Dose Escalation) and Part 2 (Expansion). The purpose of this study is to evaluate the safety (including the recommended Phase II dose), pharmacokinetics (the amount of VS-4718 in your blood) and the anti-cancer activity of VS-4718. The pharmacodynamic effects (genes or proteins that may predict or show how your body may respond to VS-4718) will also be examined in tumor biopsies and blood samples.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 48 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Study of VS-4718, a Focal Adhesion Kinase Inhibitor, in Subjects With Metastatic Non-Hematologic Malignancies
Study Start Date : June 2013
Actual Primary Completion Date : April 2017
Actual Study Completion Date : June 2017

Arm Intervention/treatment
Experimental: VS-4718
Oral VS-4718 administered BID (QD during first cohort) during a 28 day cycle.
Drug: VS-4718

Primary Outcome Measures :
  1. Assess the safety and tolerability of VS-4718 in subjects with metastatic non-hematologic malignancies [ Time Frame: Expected average of 12 weeks from start of treatment to end of treatment ]
    Serious Adverse events, Adverse events and their frequency, duration and severity, physical examination, laboratory parameters, vital signs and ECGs as determined based on CTCAE (Common Toxicity Criteria for Adverse Effects) V4.03. A Safety monitoring committee will review safety information.

  2. Establish the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of VS-4718 in subjects with metastatic non-hematologic malignancies [ 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 VS-4718 as determined by number of participants with dose limiting toxicities related to VS-4718. Observations related to pharmacokinetics, pharmacodynamics, and any VS-4718 related toxicities may be included in the rationale supporting the RP2D and will not exceed the MTD.

Secondary Outcome Measures :
  1. Evaluate the efficacy of VS-4718 [ Time Frame: Every 8 weeks to end of treatment, expected average of 16 weeks ]
    Response rate and progression-free survival as determined by Response Evaluation Criteria In Solid Tumors (RECIST), version 1.1

  2. Evaluate duration of response to VS-4718 compared with duration of response to prior therapy. [ Time Frame: Expected average of 16 weeks from start of treatment to end of treatment ]
  3. Assess the pharmacokinetics of VS-4718 [ Time Frame: Time points on Day 1, 2, 8, 15, 16, and 29 ]
    PK (pharmacokinetics) parameters, including but not limited to clearance, plasma concentration, AUC (Area Under Curve, 0-24 and 0-t), Cmax, Tmax, and T1/2

  4. Evaluate biomarkers of VS-4718 activity [ Time Frame: Day 1 and Day 15 of treatment ]
    Pre and post dose biomarker analysis in serum and tumor samples to identify possible prognostic factors to VS-4718 response

  5. Examine if the tumor expression status of pFAK and other plasma biomarkers correlates with response to VS-4718 therapy [ Time Frame: From start of treatment to end of treatment, an expected average of 16 weeks ]
    Tumor expression status (pFAK, cancer stem cells, CSC, and other biomarkers) compared with response to VS-4718, as determined by Response Evaluation Criteria In Solid Tumors (RECIST), version 1.1
