A multicentre, open-label, single-arm, molecular profiling study of patients with EGFR mutation-positive locally advanced or metastatic NSCLC treated with osimertinib.
Name: Osimertinib
Description: To characterize the frequency of genetic and proteomic markers at disease progression regardless of their prevalence.
Measure: Proportion of patients with a given tumour genetic and proteomic marker at the point of disease progression as defined by the Investigator Time: Tumour Genetic and Proteomic markers will be assessed from tissue samples collected prior to initiation of treatment and at the time of disease progression for max 4.2 yearsDescription: PFS is defined as the time from first dose of osimertinib until the date of Investigator assessed RECIST 1.1-defined progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from therapy or receives another anticancer therapy prior to progression.
Measure: Progression-free survival (PFS) Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: ORR is defined as the number (%) of patients with at least one visit response of complete response or partial response that is confirmed at least 4 weeks later.
Measure: Objective Response Rate (ORR) Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: DoR is defined as the time from the date of first documented response, (that is subsequently confirmed) until date of documented progression or death in the absence of disease progression, the end of response should coincide with the date of progression or death from any cause used for the PFS endpoint.
Measure: Duration of Response (DoR) Time: From time of first documented response until date of documented progression or death in the absence of disease progression or end of study up to max 4.2 yearsDescription: TTD is defined as the time from the date of first dose of osimertinib to the earliest of treatment discontinuation or death.
Measure: Time toTreatment Discontinuation or Death (TTD) Time: At every visit from enrolment to end of treatment or death or end of study for max 4.2 yearsDescription: TFST is defined as the time from the date of first dose of osimertinib to the earlier of the date of anticancer therapy start date following study treatment discontinuation, or death.
Measure: Time to first subsequent therapy or Death (TFST) Time: At every visit from enrolment to start of first subsequent therapy or death or end of study for max 4.2 yearsDescription: Percentage of patients who have a best overall response, complete response, partial response or stable disease.
Measure: Disease Control Rate Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: PFS will additionally be analysed in patient subgroups defined by molecular profile, including but not limited to: Positive pre-treatment T790M mutation, epidermal growth factor receptor (EGFR) Ex 19 del or L858R mutation and EGFR Ex19 del or L858R detectable in plasma derived circulating tumour deoxyribonucleic acid (ctDNA).
Measure: PFS in patient subgroups defined by molecular profile Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: ORR will additionally be analysed in patient subgroups defined by molecular profile, including but not limited to: Positive pre-treatment T790M mutation, EGFR Ex 19 del or L858R mutation and EGFR Ex19 del or L858R detectable in plasma derived ctDNA.
Measure: ORR in patient subgroups defined by molecular profile Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: TTD will additionally be analysed in patient subgroups defined by molecular profile, including but not limited to: Positive pre-treatment T790M mutation, EGFR Ex 19 del or L858R mutation and EGFR Ex19 del or L858R detectable in plasma derived ctDNA.
Measure: TTD in patient subgroups defined by molecular profile Time: At every visit from enrolment to start of first subsequent therapy or death or end of study for max 4.2 yearsDescription: Tumour shrinkage is defined as the best change from baseline in the sum of diameters of target lesions. Tumour shrinkage/depth of response will additionally be analysed in patient subgroups defined by molecular profile, including but not limited to: Positive pre-treatment T790M mutation, EGFR Ex 19 del or L858R mutation and EGFR Ex19 del or L858R detectable in plasma derived ctDNA.
Measure: Tumour shrinkage/depth of response in patient subgroups defined by molecular profile Time: At baseline and every 8 weeks from enrolment until disease progression or death or end of study for max 4.2 yearsDescription: The patient characteristics will include: gender (male/female), age (<65yrs/>65yrs), race (Asian/non Asian), and WHO Performance Status (0/1). These will be summarized by subgroups defined by molecular profile, including but not limited to: Positive pre-treatment T790M mutation, EGFR Ex 19 del or L858R mutation and EGFR Ex19 del or L858R detectable in plasma derived ctDNA.
Measure: Proportion of patients with pre-specified characteristics will be summarised by molecular profile Time: At baselineDescription: To summarize the safety and tolerability profile of osimertinib as first-line EGFR tyrosine kinase inhibitor therapy for patients with EGFR mutation-positive locally advanced or metastatic non-small cell lung cancer
Measure: Adverse events graded by Common Terminology Criteria for Adverse Events version 4.0 Time: At every visit from signing informed consent until 28 days after last dose of study treatmentAllocation: N/A
