Brief Summary:
This study will compare the efficacy of the investigational agent sitravatinib in combination with nivolumab versus docetaxel in patients with advanced non-squamous NSCLC who have previously experienced disease progression on or after platinum-based chemotherapy and checkpoint inhibitor therapy.

Condition or disease Intervention/treatment Phase
Metastatic Non-Squamous Non-Small Cell Lung Cancer Biological: Nivolumab Drug: Sitravatinib Drug: Docetaxel Phase 3

Detailed Description:
Sitravatinib (MGCD516) is an orally-available, small molecule inhibitor of a closely related spectrum of receptor tyrosine kinases (RTKs) including MET, TAM (Tyro3, AXL, MERTK) family, VEGFR family, PDGFR family, KIT, FLT3, TRK family, RET, DDR2, and selected EPH family members. Nivolumab is a human IgG monoclonal antibody that binds to the PD-1 receptor and selectively blocks the interaction with its ligands PD-L1 and PD-L2, thereby releasing PD-1 pathway mediated inhibition of the immune response, including anti-tumor immune response. RTKs have been implicated in mediating an immunosuppressive tumor microenvironment, which has emerged as a potential resistance mechanism to checkpoint inhibitor therapy. Inhibition of these RTKs by sitravatinib may augment anti-tumor immune response and improve outcomes by overcoming resistance to checkpoint inhibitor therapy.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Nivolumab and Sitravatinib
Nivolumab will be administered by intravenous infusion over 30 minutes at 240 mg every 2 weeks or at 480 mg every 4 weeks. Sitravatinib capsules will be administered orally, once daily.
 Biological: Nivolumab
Nivolumab is an antibody directed at the programmed death receptor-1 (PD-1), blocking its interaction with PD-L1 and PD-L2.
Other Name: Opdivo

Drug: Sitravatinib
Sitravatinib is a small molecule inhibitor of receptor tyrosine kinases.
Other Name: MGCD516
Active Comparator: Docetaxel
Docetaxel will be administered by intravenous infusion at 75 mg/m2 over 1 hour every 3 weeks.
 Drug: Docetaxel
Docetaxel is an anti-neoplastic agent that acts by disrupting the microtubular network in cells.
Other Name: Taxotere


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: 36 Months ]
    OS is defined as time from date of randomization to date of death due to any cause


Secondary Outcome Measures :
  1. Adverse Events (AEs) [ Time Frame: 36 Months ]
    Frequency of patients experiencing treatment-emergent AEs

  2. Objective Response Rate (ORR) [ Time Frame: 36 Months ]
    ORR defined as complete response (CR) or partial response (PR) per RECIST version 1.1 recorded from randomization until disease progression or start of new anti-cancer therapy

  3. Progression-Free Survival (PFS) [ Time Frame: 36 months ]
    PFS is defined as the time from randomization to the date of the first documentation of objective disease progression or death due to any cause
