MA14.06 - Nivolumab in Never Smoker Patients with Advanced Squamous NSCLC: Results from the Italian Expanded Access Programme (EAP) (ID 4765)
16:00 - 17:30 | Author(s): C. Bengala
Nivolumab is the first checkpoint inhibitor approved for the treatment of Sq-NSCLC to show a survival benefit vs the standard of care docetaxel in the randomised, phase III, CheckMate 017 study. In the nivolumab development program, a greater clinical benefit was shown in current and former smokers than in never smokers. Nevertheless, no data are available in this respect from a real world setting. For this reason, we decided to use the data collected in the EAP in order to assess the effectiveness and tolerability of nivolumab treatment in the never smoker patient population.
Nivolumab was provided upon physician request for patients aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Patients included in the analysis had received ≥1 dose of nivolumab and were monitored for adverse events using Common Terminology Criteria for Adverse Events.
Of 372 patients with Sq-NSCLC participating in the EAP in Italy, 38 (10.2%) were never smokers, a proportion very similar to the one observed in Checkmate 017 (10%). With a median number of doses of 8 (range, 1–22) and a median follow-up of 5.6 months, the disease control rate in this group was 50%, including 9 patients with a partial response and 10 with stable disease. Eight patients were treated beyond RECIST-defined progression, with 4 of them achieving disease control. As of April 2016, median progression-free survival and overall survival were 3.5 months and not reached, respectively. 17 patients (44.7%) discontinued treatment for any reason except toxicity and 5 (13.1%) discontinued due to AE.
These preliminary results, although obtained from a small sample size, suggest that nivolumab is effective and well tolerated in a never smoker group of patients with advanced Sq-NCLCS in the real life and warrant further investigation in this area.
