The Patient-Reported Outcomes in ALK Positive Advanced NSCLC in China

A total of 800 patients with ALK+ NSCLC will be enrolled in this study. The actual number of sites can be increased or decreased as appropriate. In order to approach the real world medication situation, the number of patients treated with Alectinib will be 400 cases; the number of patients treated with Lorlatinib will be 200 cases; the number of patients treated with the other ALK-TKIs will be 200 cases in total. Study Population The study population is intended to follow the real-world use of ALK-TKIs treatment; therefore, minimal inclusion and exclusion criteria will be used. The study population will comprise patients treated with ALK-TKIs for ALK-positive advanced NSCLC. Patients in all 3 cohorts who meet any of the following criteria will be excluded from study entry: * Patients receiving ALK-TKIs as investigational study drugs in a clinical trial for the treatment of advanced NSCLC * Patients participating in clinical trials within 28 days prior to initiation of study treatment * Pregnant, lactating, or breastfeeding women Statistical Methods Primary Analysis The primary objective for this study is to describe the patient-reported outcomes in patients with ALK+ locally advanced or metastatic NSCLC who received ALK-TKIs as first-line treatment in the real world situation. Analyses were conducted using the full analysis set (FAS), which comprised all 3 cohorts of patients enrolled in the study population with at least baseline data in eCRFs. The PRO analysis set consists of all patients in the FAS who completed at least one baseline questionnaire and at least one post baseline questionnaire.Patients with no post-baseline information will be censored at the date of enrollment. Proportion of patients reporting clinically meaningful deterioration (decrease from baseline of ≥ 10 points) in the subscales of EORTC QLQ-LC13 (fatigue, chest pain) and QLQ-C30 (cognitive, physical and role functioning) will be summarized. Change(s) from baseline scores will be conducted for fatigue, chest pain as measured by the EORTC QLQ-LC13 and cognitive functioning, physical and role functioning by QLQ-C30 at each assessment time point. Presence, frequency of occurrence, severity, and/or degree of interference with daily function of symptomatic treatment toxicities (swelling, rash, blurred vision, anxious, sad) as assessed through use of the NCI PRO-CTCAE Frequency of patients' response of the degree they are troubled with treatment symptoms, as assessed through use of the single-item EORTC Item List (IL46) Summary statistics (number of patients, mean, standard deviation, median, minimum, maximum, 95% CI) will be applied for baseline characteristics and absolute score(s). Secondary analysis Incidence and severity of adverse events based on the NCI CTCAE v5.0 and the rate of ALK-TKIs treatment changes by different reasons will be summarized to evaluate the safety and tolerability of ALK-TKIs as first-line treatment in each three cohorts. All variables will be summarized by number of patients, mean, standard deviation, median, minimum, maximum. Analyses were conducted using SAS statistical software, version 9.4 (SAS Institute Inc, Cary, North Carolina).
