A Study to Assess the Safety and Tolerability of Atezolizumab in Combination With Other Immune-Modulating Therapies in Participants With Locally Advanced or Metastatic Solid Tumors

Overview

  • Study type

    Interventional
  • Study phase

    I
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This global, multicenter, open-label study will evaluate the safety and tolerability of atezolizumab in combination with other immune-modulating therapies in the treatment of selected advanced or metastatic malignancies. The atezolizumab plus ipilimumab arm (Arm A) will focus primarily on participants with advanced or metastatic non-small cell lung cancer (NSCLC). The atezolizumab plus interferon alfa-2b arm (Arm B), plus pegylated interferon alfa-2a (PEG−interferon alfa-2a, Arm C), and atezolizumab plus PEG-interferon Alfa-2a plus bevacizumab (Arm D) will enroll participants with advanced or metastatic renal cell carcinoma (RCC), metastatic NSCLC and melanoma. The atezolizumab plus obinutuzumab) (Arm E) will enroll participants with recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). Atezolizumab will be administered as intravenous (IV) infusion every 3 weeks (q3w).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
