136PD_PR - 3-year survival and duration of response in randomized phase II study of atezolizumab (atezo) vs docetaxel (doc) in 2L+ NSCLC (POPLAR) (ID 607)
07:45 - 09:00 | Presenting Author(s): J. Mazieres
- Abstract
Background:
Atezo (anti–PD-L1) has demonstrated OS benefit over doc in a randomized Phase II study, POPLAR, in patients with advanced NSCLC. This benefit has been confirmed in the randomized Phase III study OAK (Rittmeyer, 2017). The 3-year survival analysis of the POPLAR study presented here describes the longest survival follow-up reported to date of an all-comer randomized PD-L1/PD-1 immunotherapy trial in 2L + NSCLC.
Methods:
Patients were randomized 1:1 to receive atezo (1200 mg) or doc (75 mg/m[2]) IV q3w. Tumors were prospectively evaluated for tumor cell (TC) or tumor-infiltrating immune cell (IC) PD-L1 expression using the VENTANA SP142 IHC assay. Landmark OS was estimated using the Kaplan-Meier method. Data cutoff, April 7, 2017; minimum follow-up, 3 years.
Results:
The 2-year and 3-year survival with atezo vs doc were 32.2% vs 16.6% and 18.7% vs 10.0%, respectively. The long-term OS benefit of atezo vs doc was observed across histology and PD-L1 expression subgroups (Table). While the TC3 or IC3 subgroup derived the greatest OS benefit, the TC0 and IC0 subgroup also had improved long-term OS with atezo vs doc. The ITT ORR was 15% in both atezo and doc arms, but the median duration of response was 3 times longer with atezo (22.3 months [95% CI: 11.6, 31.1] vs 7.2 months [95% CI: 5.8, 12.2] with doc). Seven of the 11 doc-arm 3-year survivors received subsequent non-protocol therapy with anti–PD-L1/PD-1 agents. Atezo had a favorable safety profile compared with doc that was consistent with previous reports.Table:Landmark OS in the ITT, PD-L1 expression, and histology subgroups in POPLAR

Conclusions:
Atezo demonstrates superior 2-year and 3-year OS benefit compared with doc, and this benefit is observed across histology and PD-L1 expression subgroups (including TC0 and IC0). Atezo is well tolerated, and responses are highly durable. These results are consistent with long-term OS results from OAK (Satouchi, WCLC 2017). Acknowledgement of contribution: M. Gandhi, W. Yu, C.
