Primary Outcome Measures :
  1. Part A: Determine optimal regimen of VS-6766 monotherapy or in combination with defactinib [ Time Frame: From start of treatment to confirmation of response; 24 weeks ]
    Confirmed overall response rate per RECIST 1.1

  2. Part B: To determine the efficacy of the optimal regimen identified from Part A [ Time Frame: From start of treatment to confirmation of response; 24 weeks ]
    Confirmed overall response rate per RECIST 1.1


Secondary Outcome Measures :
  1. Overall Response Rate as assessed by Investigator [ Time Frame: From start of treatment to confirmation of response; 24 weeks ]
    Proportioned subjects achieving a CR or PR as assess by the investigator

  2. Duration of Response (DOR) [ Time Frame: Time from the first documentation of response to first documentation of progressive disease or death due to any cause, greater than or equal to 6 months ]
    From time of first response to PD as assessed by the IRC

  3. Disease Control Rate (DCR) [ Time Frame: Greater than or equal to 8 weeks ]
    CR+PR+stable disease as assessed by the IRC

  4. Progression Free Survival (PFS) [ Time Frame: Up to 5 years ]
    From time of first dose of study intervention to PD or death for any cause

  5. Overall Survival (OS) [ Time Frame: Up to 5 years ]
    From time of first dose of study intervention to death
