Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Metastatic EGFR mutated NSCLC patients who developed acquired resistance with a secondary EGFR mutation T790M. These patients were started on osimertinib (80mg daily orally until disease progression/significant toxicities) and clinical outcomes of these patients will be observed (response rate, progression free survival and overall survival). The duration of observation will be a minimum of one year since the start of treatment with osimertinib. Maximum duration of observation will be 3 years from the start of treatment.

Outcomes
Primary outcome [1] 302588 0
Objective response rate (ORR) is defined as the proportion of patients with a documented complete response, partial response (CR + PR) based on iRECIST criteria/investigator defined.
Timepoint [1] 302588 0
3 months into treatment with osimertinib
Secondary outcome [1] 336450 0
Overall survival (OS) is a secondary endpoint of this study.
It is defined as the time from the first dose of Osimertinib to the date of death due to any cause. Patients who are alive at the time of the final analysis or who have become lost to follow-up will be censored at their last known alive date. All patients who meet the eligibility criteria will be included in the analysis of OS. A Kaplan-Meier estimate of proportions of patients alive will be displayed. The 95% confidence intervals for the median OS will be computed using the method of Brookmeyer and Crowley. The effect of potential prognostic factors on survival (ie. RAF) will be assessed using Cox regression model. The Schoenfeld residual plots will be used to check the model assumption for the Cox regression.
Timepoint [1] 336450 0
analysis of OS will be after minimum of one year follow up ie. assessed one year after the last patient commence on osimertinib therapy.
Secondary outcome [2] 336602 0
Progression free survival (PFS) is a secondary endpoint of this study, which is defined as the time from the first dose of Osimertinib to the date of the first documented disease progression (based on investigator-defined progression) or death due to any cause. A patient who stops treatment with study drug and goes on to receive alternative therapy for NSCLC, prior to documentation of disease progression, will be censored on the date alternative therapy began. If a patient has not progressed or received alternative therapy, PFS will be censored on the date of the last disease assessment. All patients will be included in the analysis of PFS. All analyses for OS will be similarly performed for PFS.
Timepoint [2] 336602 0
analysis of PFS will be after minimum of one year follow up ie. assessed one year after the last patient commence on osimertinib therapy.

Statistical methods / analysis
Sample Size: We estimate to have approximately 70 patients for this study. The patients will be stratified based on RAF of T790M (divided into 2 groups: (1) Group 1 = RAF greater than or equal to 10%; (2) Group 2= RAF less than 10%. Based on our preliminary data of 15 patients, 1/3 of the patients will be in group 1 and 2/3 of the patients will be in group 2, giving a 1:2 ratio. Assuming response rate of 70% for group 1 and 30% for group 2, 66 subjects are needed to achieve 80% power using a 2-sided Type 1 error of 5%.
Cox-regression will be used to analysed data for PFS and OS. Fishers exact test will be used to analyse the association between Relative Alleilic frequency of T790M with response rate.
