A Study Comparing Alectinib With Crizotinib in Treatment-Naive Anaplastic Lymphoma Kinase-Positive Advanced Non-Small Cell Lung Cancer Participants

PFS was assessed as time to disease progression or death whichever occurred first by investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (v1.1) Criteria. As per RECIST v1.1, disease progression is a 20% increase in the sum of the diameters of target lesions, an increase in size of measurable lesions by at least 5 millimeter (mm) and the appearance of new lesions.

PFS was assessed percentage of participants with disease progression or death whichever occurred first by investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (v1.1) Criteria. As per RECIST v1.1, disease progression is a 20% increase in the sum of the diameters of target lesions, an increase in size of measurable lesions by at least 5 millimeter (mm) and the appearance of new lesions.

PFS was assessed as time to disease progression or death whichever occurred first by IRC assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (v1.1) Criteria. As per RECIST v1.1, disease progression is a 20% increase in the sum of the diameters of target lesions, an increase in size of measurable lesions by at least 5 mm and the appearance of new lesions.

CNS progression was assessed as percentage of participants with an event defined as time from randomization until first radiographic evidence of CNS progression by IRC. The risk for a CNS progression without a prior non-CNS progression with alectinib compared with crizotinib.

ORR was defined as the percentage of participants who attained CR or PR. As per RECIST v1.1, CR: Disappearance of all target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm, PR: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters.

DOR was defined as the time from when response (CR or PR) was first documented to first documented disease progression or death, whichever occurred first. DOR was evaluated for participants who had a best overall response (BOR) of CR or PR.

Overall survival (OS) was defined as the time from randomization to death from any cause.

Overall survival (OS) was defined as the time from randomization to death from any cause.

CNS ORR was defined as the percentage of participants who attained CR or PR and had measurable/non-measurable CNS lesions at baseline. As per RECIST v1.1, CR: Disappearance of all target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm, PR: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters.

CNS DOR was defined as the time from when response (CR or PR) was first documented to first documented disease progression or death, whichever occurred first. DOR was evaluated for participants who had a best overall response (BOR) of CR or PR.

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

The EORTC QLQ-30 module generated one multiple-item scale score assessing dyspnea and a series of single item scores assessing chest pain, arm/shoulder pain, pain in other parts, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. All the scales and single-item scores were linearly transformed so that each score ranged from 0 to 100. A higher score on the global health and functioning subscales is indicative of better functioning. Confirmed clinically meaningful deterioration in global health status or function is defined as a >or=10-point decrease from baseline in a symptom score that must be held for at least two consecutive assessments or an initial >or=10-point decrease from baseline followed by death within 5 weeks from the last assessment.

The EORTC QLQ-LC13 module generated one multiple-item scale score assessing dyspnea and a series of single item scores assessing chest pain, arm/shoulder pain, pain in other parts, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis.

A higher score on the global health and functioning subscales is indicative of better functioning. Confirmed clinically meaningful deterioration in lung cancer symptoms is defined as a >or=10-point increase from baseline in a symptom score that must be held for at least two consecutive assessments or an initial >or=10-point increase above baseline followed by death within 5 weeks from the last assessment.

The EORTC QLQ-C30 questionnaire consisted of 30 questions generating five functional scores (physical, role, cognitive, emotional, and social); a global health status/global quality of life scale score; three symptom scale scores (fatigue, pain, and nausea and vomiting); and six stand alone one-item scores that capture additional symptoms (dyspnea, appetite loss, sleep disturbance, constipation, and diarrhea) and perceived financial burden. All the scales and single-item scores were linearly transformed so that each score ranged from 0 to 100. A higher score on the global health and functioning subscales is indicative of better functioning.
