Overview

Study Title

A Phase 1b/2, Open-Label, Randomized Study of Daratumumab Administered in Combination with Atezolizumab Compared with Atezolizumab Alone in Subjects with Previously Treated Advanced or Metastatic Non-Small Cell Lung Cancer

Summary

The purpose of this study is to compare the overall response rate (ORR) in non-small cell lung cancer (NSCLC) participants treated with daratumumab in combination with atezolizumab versus atezolizumab alone.

Objective

To compare the overall response rate (ORR) in subjects treated with daratumumab in combination with atezolizumab versus atezolizumab alone.

Inclusion Criteria

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Have histologically or cytologically confirmed advanced or metastatic non-small cell lung cancer (NSCLC) (Stage IIIb or IV)
  • Measurable disease, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 response criteria
  • Known programmed death-ligand 1 (PD-L1) tumor status as determined by an immunohistochemistry (IHC) assay performed by the central laboratory on tissue obtained at Screening
  • A woman of childbearing potential must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta- hCG]) at Screening within 14 days prior to study drug administration
  • Inclusion Criteria for Crossover: Participants must have been randomized to Arm A of the study and had radiographic disease progression according to RECIST 1.1; Participants must have a mandatory biopsy at the time of disease progression according to RECIST 1.1 prior to crossing over (If not clinically feasible, discussion with Sponsor is required); The first dose of atezolizumab in the crossover arm should be within 42 days of last dose but no less than 21 days from the last dose prior to crossing over.

  • Exclusion Criteria

  • Received any of the following prescribed medications or therapies in the past: Anti-cluster of differentiation(CD)38 therapy, including daratumumab; CD137 agonists, immune checkpoint inhibitors including but not limited to anti-cytotoxic-T-lymphocyte-associated antigen 4 (CTLA-4), anti-PD-1, and anti-PD-L1 therapies.
  • Known to be seropositive for human immunodeficiency virus (HIV)
  • Prior allogeneic bone marrow transplantation or solid organ transplant
  • History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
  • Active hepatitis B, defined by a positive test for hepatitis B surface antigen [HBsAg] or prior history of hepatitis B, defined by presence of antibodies to hepatitis B core antigen [anti-HBc], regardless of hepatitis B surface antibody [anti-HBs] status; active hepatitis C or prior history of hepatitis C (anti-HCV positive), except in the setting of a sustained virologic response (SVR), defined as aviremia 12 weeks after completion of antiviral therapy. If hepatitis C virus (HCV) antibodies are detected, an HCV RNA test for viral load by polymerase chain reaction (PCR) should be performed at least 12 weeks after completion of antiviral therapy to rule out active infection
  • Exclusion Criteria for Crossover: Received any subsequent anti-cancer therapies from the time between the last dose of atezolizumab prior to the first administration of study drug after crossing over; Whole brain radiation within 28 days or other radiotherapy within 14 days prior to first administration of study drug after crossing over.
