A Study of Brigatinib in Participants With Anaplastic Lymphoma Kinase-Positive (ALK+), Advanced Non-Small-Cell Lung Cancer (NSCLC) Progressed on Alectinib or Ceritinib

Confirmed ORR is defined as the percentage of the participants who are confirmed to have achieved complete response (CR) or partial response (PR), per RECIST version 1.1 (confirmed ≥4 weeks after initial response), after the initiation of study treatment. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis and PR: at least a 30% decrease in the sum of the longest diameters (SLD) of target lesions taking as reference the Baseline sum diameters. Percentages were rounded off to the nearest single decimal place.

Confirmed ORR is defined as the percentage of the participants who are confirmed to have achieved CR or PR, per RECIST version 1.1 (confirmed ≥4 weeks after initial response), after the initiation of study treatment. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis and PR: at least a 30% decrease in the SLD of target lesions taking as reference the baseline sum diameters. Percentages were rounded off to the nearest single decimal place.

DOR is defined as the time interval from the time that the measurement criteria are first met for CR or PR until the first date that the progressive disease (PD) is objectively documented, or death. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis. PR: at least a 30% decrease in the SLD of target lesions taking as reference the Baseline sum diameters. PD: SLD increased by at least 20% from the smallest value on study (including Baseline, if that is the smallest). SLD must also demonstrate an absolute increase of at least 5 mm (2 lesions increasing from, for example, 2 mm to 3 mm, does not qualify).

PFS is defined as the time interval from the date of the first dose of the study treatment until the first date at which disease progression is objectively documented, or death due to any cause, whichever occurs first. PFS was censored for participants without documented disease progression or death.

DCR is defined as the percentage of participants who have achieved CR, PR or stable disease (SD) (in the case of SD, measurements must have met the SD criteria at least once after study entry at a minimum interval of 6 weeks) after the initiation of study treatment. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis. PR: at least a 30% decrease in the SLD of target lesions taking as reference the baseline sum diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Percentages were rounded off to the nearest single decimal place.

Time to response is defined as the time interval from the date of the first dose of the study treatment until the initial observation of CR or PR. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis. PR: at least a 30% decrease in the SLD of target lesions taking as reference the baseline sum diameters.

Confirmed iORR is defined as the percentage of the participants who have achieved CR or PR in the brain per a modification of RECIST version 1.1, after the initiation of study treatment, in participants with intracranial brain metastases at baseline. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis. or partial response or PR: at least a 30% decrease in the SLD of target lesions taking as reference the baseline sum diameters. Percentages were rounded off to the nearest single decimal place.

Duration of intracranial response is defined as the time interval from the time that the measurement criteria are first met for CR or PR until the first date that PD (including baseline, if that is the smallest). SLD must also demonstrate an absolute increase of at least 5 mm. (2 lesions increasing from, for example, 2 mm to 3 mm, does not qualify) in the brain is objectively documented or death, in participants with intracranial metastases at baseline. CR: disappearance of all extranodal target lesions and all pathological lymph nodes must have decreased to <10 mm in short axis. or partial response or PR: at least a 30% decrease in the SLD of target lesions taking as reference the baseline sum diameters in the brain. PD: SLD increased by at least 20% from the smallest value on study.

iPFS is defined as the time interval from the date of the first dose of the study treatment until the first date at which intracranial brain disease progression is objectively documented, or death due to any cause, whichever occurs first, in participants with intracranial metastases at enrollment. iPFS will be censored for participants without documented intracranial disease progression or death.

OS is defined as the time interval from the date of the first dose of the study treatment until death due to any cause. It was censored on the date of last contact for those participants who were alive.

An adverse event (AE) means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. This includes any newly occurring event, or a previous condition that has increased in severity or frequency since the administration of study drug. TEAE: any AE either reported for the first time or worsening of a pre-existing event after first dose of study drug and within 30 days of the last administration of study drug.

EORTC QLQ-C30 incorporates 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, nausea and vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). EORTC QLQ-C30 contains 28 questions (4-point scale where 1=Not at all [best] to 4=Very Much [worst]) and 2 questions (7-point scale where 1=Very poor [worst] to 7= Excellent [best]). Raw scores are converted into scale scores ranging from 0 to 100. For the functional scales and the global health status scale, higher scores represent better quality of life (QOL); for the symptom scales, lower scores represent better QOL. Improvement is defined as a change from baseline of 10 or more points higher for functional scales and 10 or more points lower for symptom scales.

HRQOL scores will be assessed with EORTC, its lung cancer module QLQ-LC13. QLQ-LC13 contains 13 questions assessing lung cancer-associated symptoms (cough, hemoptysis, dyspnea, and site-specific pain), treatment-related side effects (sore mouth, dysphagia, peripheral neuropathy, and alopecia), and use of pain medication. Scale score range: 0 to 100. Higher symptom score = greater degree of symptom severity. Improvement is defined as a change from baseline of 10 or more points lower for symptom scales.
