First Line Osimertinib for EGFR Mutation-positive Non-Small Cell Lung Cancer in Real World Chinese Setting

Carcinoma, Non-Small-Cell Lung Clinical Trial

Official title: A Prospective, National, Multi-centric, Non-interventional Study of First Line Osimertinib in Chinese Patients With Locally Advanced/Metastatic，EGFR Mutation-positive NSCLC in Real World Setting

Status Active, not recruiting

Clinical Trial Summary

The results of phase III FLAURA study showed a significant PFS benefit for first-line Osimertinib versus standard EGFR-TKIs in patients with EGFR mutation-positive NSCLC, the median PFS was 18.9 months and 10.2 months, respectively. However, only 136 Chinese patients were enrolled in FLAURA study. The objectives of this study are to assess the efficacy and safety of Osimertinib in a real world setting in Chinese patients with locally advanced or metastatic, treatment naïve, epidermal growth factor receptor (EGFR) mutation-positive Non-Small Cell Lung Cancer (NSCLC).

Clinical Trial Description

Total of ~30 study sites are selected for conducting this observational study. Eligible patients will be prospectively and consecutively included. Therefore, the clinical practice in the selected patients group can represent the "real-world" situation in China, and the patient's medical record will be well documented and archived in those hospitals. All data defined in the protocol will be collected during the study and entered in the Electric Data Capture (EDC), being consistent to the patients' medical records.

The most important bias of the study is that patients' characteristics will affect the treatment duration, efficacy and safety, such as, higher proportion of patients with WHO PS 2~3 enroll in the study will result in shorter TTD, poorer effectiveness and higher toxicities than expected. The ~30 sites are not randomly selected and potential selection bias exists. To minimize enrolment bias, the patients who are eligible and consent to participate in the current study will be enrolled consecutively as per protocol and without personal preference from investigators.

The self-selection bias may exit for the willingness and non-willingness participants. We'll try our best to discuss with the non-willingness participants to make sure the consistency/comparative between the willingness and non-willingness participants.

There could be a certain percentage of patients who would lost to follow up, it is unavoidable in clinical study, and is more common in real world study. We can minimize the bias by selecting the hospitals with normative and high-quality clinical practice, trying to collect the reason of lost to follow up and enhancing patient management during the follow up. The above bias is acceptable as this is a "real-world" study. Only descriptive analysis will be performed for the primary, secondary and exploratory objectives. No statistical comparisons between subgroups will be done. ;
