Percentage of Participants With Objective Response (OR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 in Part 2
The OR is defined as confirmed complete response (CR) or confirmed partial response (PR) based on RECIST v1.1 guidelines. The CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. The PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between.
Time frame: From Day 1 through 90 days of the last dose of study drug (approximately 37 months)
Duration of Response (DoR) Per RECIST v 1.1 for Parts 1 and 2
The DoR is defined as duration from the first documentation of OR (confirmed CR or PR) to the first documented disease progression based on RECIST v1.1 guidelines or death due to any cause, whichever occurs first. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between. The progressive disease is defined at least a 20% increase in sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since treatment started, the appearance of one or more new lesions, or unequivocal progression of existing non-target lesions. The DoR was analyzed using Kaplan-Meier method.
Time frame: From Day 1 through 90 days of the last dose of study drug (approximately 37 months)
Percentage of Participants With Disease Control (DC) in Parts 1 and 2
The DC is defined as percentage of participants with CR, PR, or stable disease (SD, which was maintained by \>= 8 week) based on RECIST v1.1 guidelines. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. The SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression, taking as reference the smallest sum longest diameter since the study treatment started, and non-progressive disease and not evaluable or no non-target lesion.
Time frame: From Day 1 through 90 days of the last dose of study drug (approximately 37 months)
Progression Free Survival (PFS) for Parts 1 and 2
The PFS is defined as the time from the start of study treatment until the documentation of disease progression based on RECIST version 1.1 or death due to any cause, whichever occurs first, regardless of whether the participant received subsequent anticancer treatment prior to progression. The progressive disease is defined at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started, the appearance of one or more new lesions, or unequivocal progression of existing non-target lesions. Participants who were alive and progression-free at the time of data cut-off for analysis had PFS censored at the last tumor assessment date. The PFS was estimated using Kaplan-Meier method.
Time frame: From Day 1 through 90 days of the last dose of study drug (approximately 37 months)
Overall Survival (OS) for Parts 1 and 2
The OS is defined as the time from the start of study treatment until death due to any cause. Participants who are alive at the time of data cut-off had OS censored at the last known to be alive date. The OS was estimated using Kaplan-Meier method.
Time frame: From Day 1 through 90 days of the last dose of study drug (approximately 37 months)
Percentage of Participants With OR by T790M Status at Baseline (Determined by a Central Laboratory) for Parts 1 and 2
The T790M status was determined by plasma testing in a central laboratory at Baseline (Days -28 to -1). The OR is defined as confirmed CR or confirmed PR based on RECIST v1.1 guidelines. The CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. The PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between. Cell-free circulating tumor deoxyribonucleic acid (ctDNA) from liquid biopsy was used as a surrogate marker for T790M status in tumor tissue.
Time frame: From Baseline (Days -28 to -1) through 90 days of the last dose of study drug (approximately 37 months)
Percentage of Participants With DC by T790M Status at Baseline (Determined by a Central Laboratory) for Parts 1 and 2
The T790M status was determined by plasma testing in a central laboratory at Baseline (Days -28 to -1). The DC is defined as percentage of participants with CR, PR, or SD (maintained by \>= 8 week) based on RECIST v1.1 guidelines. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of longest diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. The SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression, taking as reference the smallest sum longest diameter since the study treatment started, and persistence of one or more non-target lesion(s). Cell-free circulating tumor deoxyribonucleic acid (ctDNA) from liquid biopsy was used as a surrogate marker for T790M status in tumor tissue.
