Description:
Dr. Sanjay Popat, PhD, dicusses Health-related quality of life results from ALTA-1. Background: Results from ALTA-1L (NCT02737501), an international, multicenter trial, showed that brigatinib vs crizotinib as 1L ALK therapy significantly prolongs progression-free survival (PFS; HR: 0.49, 95% CI, 0.33, 0.74) in advanced ALK+ NSCLC. HRQoL was evaluated as a secondary objective. Methods: ALK+ NSCLC patients were randomized 1:1 to brigatinib 90 mg daily for 7 days, then 180 mg daily or crizotinib 250 mg twice daily as 1L ALK therapy; treatment cycles were 28 days. HRQoL was assessed with the EORTC QLQ-C30 and LC13. Change from baseline, duration of improvement and time to worsening were analyzed in the ITT-PRO population (n = 131 for both groups). Results: HRQoL compliance was > 90% for brigatinib and crizotinib. Global health status (GHS)/QoL improved starting at cycle 2, with clinically meaningful improvement (?10-point increase) noted with brigatinib at cycles 5?8, 10?13, 17 and 19 and crizotinib at cycle 6. Brigatinib substantially improved overall HRQoL vs crizotinib, as demonstrated by the estimated mean difference on change from baseline (4.1, P< 0.05) and duration of improvement for GHS/QoL (HR = 0.16, P< 0.001). Improved GHS/QoL with brigatinib vs crizotinib was also supported by improvement in several functional domains (Table) and for these symptoms (P< 0.05): fatigue, nausea/vomiting and appetite loss. No domains significantly favored crizotinib. Brigatinib showed a trend to prolong time to worsening of dyspnea vs crizotinib (HR 0.65, 95% CI 0.38, 1.12). Table: HRQoL results brigatinib vs crizotinib Clinical trial information: NCT02737501Conclusions: Consistent with the prolongation of PFS seen in 1L treatment of advanced ALK+ NSCLC, brigatinib improved HRQoL and prolonged the duration of improvement in GHS/QoL, and the majority of functional and symptom domains vs crizotinib.
