Evaluating Adjuvant Atezolizumab or Atezolizumab and Hyaluronidase-TQJS to Prevent Recurrence in Stage I Non-Small Cell Lung Cancer (NSCLC): A Randomized Phase III Trial (AASI-NSCLC)
National Cancer Institute (NCI)
Summary
This phase III trial compares the effect of atezolizumab (or atezolizumab and recombinant human hyaluronidase) to standard observation for preventing cancer return after surgery (recurrence) in patients who have undergone a complete surgical removal (resection) of stage I non-small cell lung cancer (NSCLC). Patients who have undergone resection for lung cancer are typically followed by observation or active surveillance, which involves closely watching a patient's condition but not giving treatment unless there are changes in test results. During active surveillance, patients are given certain exams and tests done on a regular schedule. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Atezolizumab and recombinant human hyaluronidase is a formulation of atezolizumab combined with an enzyme called hyaluronidase, which helps increase tissue absorption of the drug. Giving atezolizumab or atezolizumab and recombinant human hyaluronidase after resection may be effective for preventing NSCLC recurrence, and may be a better approach to treating patients with stage I NSCLC than the usual observation approach.
Description
PRIMARY OBJECTIVE: I. To compare disease-free survival (DFS) in the intent-to-treat patient population, among patients randomized to receive atezolizumab for one year (Arm B) versus (vs.) observation (Arm A). SECONDARY OBJECTIVES: I. To compare overall survival (OS) between patients randomized to atezolizumab versus observation. II. To compare recurrence-free survival (RFS) between patients randomized to atezolizumab versus observation. III. To compare lung-cancer-specific OS between patients randomized to atezolizumab versus observation. IV. To compare rates of loco-regional recurrences…
