Atezo, an anti–PD-L1 mAb, prevents the binding of PD-L1 to PD-1 and B7.1 and restores antitumor immune response. Single-agent atezo has promising efficacy and tolerability in pts with previously treated advanced NSCLC, with a survival benefit observed across PD-L1 expression levels. Given the need to improve survival of pts with early-stage NSCLC, IMpower010 (NCT02486718) has been initiated. This global Phase III, randomized, open-label trial will evaluate the efficacy and safety of atezo vs BSC, following adjuvant cisplatin (cis)-based chemo in pts with resected stage IB (tumors ≥ 4 cm)-IIIA NSCLC.

Trial design

Eligibility criteria include complete tumor resection 4-12 weeks prior to enrollment for pathologic stage IB (tumors ≥ 4 cm)-IIIA NSCLC. Pts must have adequately recovered from surgery, be eligible to receive cis-based adjuvant chemo and have an ECOG PS 0-1. Exclusion criteria include the presence of other malignancies, use of hormonal cancer or radiation therapy within 5 years, prior chemo, exposure to prior immunotherapy and autoimmune disease. Approximately 1127 pts will be enrolled regardless of PD-L1 expression status. Suitable pts will receive up to four 21-d cycles of cis-based chemo (cis [75 mg/m2 IV, d 1] + either vinorelbine [30 mg/m2 IV, d 1, 8], docetaxel [75 mg/m2 IV, d 1] or gemcitabine [1250 mg/m2 IV, d 1, 8], or pemetrexed [500 mg/m2 IV, d 1; nonsquamous NSCLC only]). Adjuvant radiation therapy is not permitted. After adjuvant treatment, eligible pts will be randomized 1:1 to receive atezo 1200 mg q3w, 16 cycles or BSC. Stratification factors include sex, histology (squamous vs nonsquamous), extent of disease (stage IB vs II vs IIIA) and PD-L1 expression by IHC (tumor cell [TC]; tumor-infiltrating immune cell [IC]; TC2/3 [≥ 5% expressing PD-L1] and any IC vs TC0/1 [< 5%] and IC2/3 vs TC0/1 and IC0/1 [< 5%]). The primary endpoint is disease-free survival; secondary endpoints include OS and safety. Exploratory endpoints include PD-L1 status, immune- and tumor-related biomarkers before, during and after treatment with atezo and at radiographic disease recurrence, or confirmation of new primary NSCLC.
