Establishing Meaningful Change Thresholds in Patient-Reported Outcomes Among Patients With Anaplastic Lymphoma Kinase-Positive Non-Small Cell Lung Cancer in ALTA-1L Trial.

Abstract

OBJECTIVES:

An earlier study from the ALTA-1L trial of patients with anaplastic lymphoma kinase-positive non-small cell lung cancer demonstrated that brigatinib produces superior health-related quality of life (QoL) outcomes over crizotinib. This study aimed to derive meaningful change thresholds (MCTs) for European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and EORTC QLQ-LC13 to refine the earlier results.

METHODS:

Patients from the ALTA-1L trial were administered the EORTC QLQ-C30 and EORTC QLQ-LC13 questionnaires. Responses were analyzed using anchor-based analysis, graphical analysis, distribution-based analysis, longitudinal responder analysis, and time to deterioration.

RESULTS:

The patient-reported outcome population comprised 262 patients who completed the EORTC QLQ-C30 at baseline and at least 1 follow-up timepoint. Both anchors (QLQ-C30 items for overall health and QoL) had correlations >0.40 or < -0.40 with all functioning domains, fatigue, pain, appetite loss, and all dyspnea scores. Within-group analysis for most scales found the derived MCT was consistent with a cutoff of 10 points for classifying individual-patient change, except for 3-item dyspnea. The probability of improvement/remaining stable was significantly greater in the brigatinib group over crizotinib for the EORTC QLQ-C30 emotional functioning, appetite loss, and constipation domains.

CONCLUSIONS:

This study derived MCTs for EORTC QLQ-C30 and QLQ-LC13 domains that may be applied in future studies and again demonstrated the superiority of brigatinib over crizotinib in health-related QoL outcomes in patients with non-small cell lung cancer.
