8006 Background: ALINA (NCT03456076) is a global, open-label, phase 3, randomized trial evaluating the efficacy and safety of adjuvant alectinib versus chemotherapy in patients with resected stage IB (≥4 cm)–IIIA, ALK+ NSCLC. A significant disease-free survival benefit was observed with alectinib vs chemotherapy (HR 0.24, 95% CI: 0.13–0.43, p<0.0001; N=257 patients in the ITT). In the adjuvant setting, where patients have received surgery with curative intent, the impact of treatment on HRQoL is an important clinical consideration. We report HRQoL results from ALINA. Methods: Patients ≥18 years old with ECOG PS 0/1 and completely resected, stage IB–IIIA, ALK+ NSCLC (UICC/AJCC 7th edition) were randomized 1:1 to receive oral 600 mg alectinib twice-daily for 2 years, or four 21-day cycles of platinum-based chemotherapy. HRQoL was an exploratory endpoint measured using the Short Form-36 version 2 (SF-36v2) health survey, which assesses functional health and well-being across 8 domains and 2 aggregated summary scores: the physical (PCS) and mental (MCS) component summary scores. Patients completed the SF-36v2 at baseline, every 3 weeks to Week 12, then every 12 weeks until disease recurrence, withdrawal of consent, death, or Week 96 (or equivalent post-chemotherapy follow-up visit). SF-36v2 was scored using norm-based scoring relative to the 2009 US general population (mean ± standard deviation: 50 ± 10), with higher scores indicating better health. Within-group minimal important differences (MIDs) were used as benchmarks for each domain, MCS and PCS. Data cut-off: 26 June 2023. Results: Completion rates were generally high (>90%) throughout the study. At baseline, most mean scores were low (<50) and were similar between study arms. With alectinib, mean scores were ≥50 for the Bodily Pain, Mental Health and Vitality domains by Week 96, suggesting that patients functioned as well as the general population on these aspects. The mean change from baseline met or exceeded MIDs for 5 domains and MCS by Week 12, and exceeded MIDs for 6 domains, MCS and PCS by Week 96. In the chemotherapy arm, mean scores were low during treatment; mean change from baseline for General Health and Vitality exceeded negative MIDs, indicating worsening in these domains. Mean scores improved in the post-chemotherapy period; in the final assessment, mean scores were ≥50 for the Bodily Pain, Mental Health and Vitality domains, and MIDs were met or exceeded for MCS, PCS and 5 domains. Conclusions: Alectinib demonstrated an improvement in most domains of HRQoL by Week 12, followed by maintenance of HRQoL on all 8 domains, MCS and PCS to Week 96. With chemotherapy, HRQoL was low during treatment, but improved in the post-chemotherapy period. Together with the DFS benefit seen in ALINA, these data support alectinib as an important new adjuvant treatment for patients with resected ALK+ NSCLC. Clinical trial information: NCT03456076 .
