ALK+ NSCLC is a subset of NSCLC present in ∼3-5% of NSCLC patients . Little is known about ALK+ NSCLC patients’ unique journeys, their perspectives on the burden of disease, and their ‘real-world’ treatment experiences. Online patient networks provide opportunities to gain valuable insights into outcomes meaningful to patients, directly from patients. The objective of this study is to develop an ALK+ NSCLC patient network to facilitate patient interaction and to conduct patient-centered research including understanding unmet needs, patient preferences, health-related quality of life (HRQoL), and product differentiation.
