Impact of Lazertinib Dose Modification on Effectiveness and Safety
- Registration Number
- NCT05716672
- Lead Sponsor
- Pusan National University Hospital
- Brief Summary
The primary objective is to evaluate Progression Free Survival (PFS) of the group (160 mg group) in which dose reduction was performed for 12 weeks after the first administration of Lazertinib.
The Secondary objectives of this study are as follows.
1. To evaluate Progression-free survival (PFS) of the group maintaining the same dose (240mg group) and the group in which dose reduction was performed (160mg group) for 12 weeks after the first administration of Lazertinib
2. In the group maintaining the same dose (240mg group) and the group in which dose reduction was performed (160mg group) for 12 weeks after the first administration of Lazertinib, Time-to-Treatment Discontinuation(TTD), Objective Response Rate(ORR), Disease Control Rate(DCR), Tumor shrinkage and Overall Survival(OS) is evaluated.
3. In the group maintaining the same dose (240mg group) and the group in which dose reduction was performed (160mg group) for 12 weeks after the first administration of Lazertinib, specific reasons (adverse event name, grade, etc.) according to Lazertinib dose adjustment is evaluated.
4. To evaluate the treatment profile of Lazertinib including duration of treatment, dose adjustment, and reason for discontinuation of treatment.
5. To evaluate the safety of Lazertinib in the 240 mg and 160 mg groups
- Detailed Description
This study is a prospective multi-center observational study, and 11 institutions will participate to enroll 200 subjects competitively. We will evaluate the efficacy and safety of Lazertinib according to maintenance of the 240mg dose and reduction of the 160mg dose for 12 weeks after the first administration of Lazertinib in non-small cell lung cancer patients confirmed to be T790M mutation-positive after treatment failure with first- or second-generation EGFR-TKIs. The study period is up to 3 years from the date of IRB approval. Follow-up is 2 years from the last subject enrollment, and data will be collected through periodic medical record review during Lazertinib administration for enrolled subjects.

- Primary Outcome Measures
Name Time Method Progression Free Survival(PFS) Up to approximately 3 years Progression-free survival is defined as the period from the start of Lazertinib administration to the time when objective disease progression is confirmed or death from any cause during treatment, whichever occurs first.
- Secondary Outcome Measures
Name Time Method Time-to-Treatment Discontinuation (TTD) Up to approximately 3 years Time-to-Treatment Discontinuation (TTD) is defined as the time from the start of Lazertinib administration to the point at which Lazertinib administration was discontinued for any reason.
Disease Control Rate (DCR) Up to approximately 3 years Disease Control Rate (DCR) is defined as the proportion of subjects whose best overall response was complete response(CR), partial response(PR), or stable disease(SD) during the period of Lazertinib administration.
Objective Response Rate(ORR) Up to approximately 3 years Objective Response Rate (ORR) is defined as the proportion of subjects whose best overall response was complete response(CR) or partial response(PR) during the period of Lazertinib administration.
Tumor shrinkage Up to approximately 3 years Tumor shrinkage is defined as the ratio of the size of the primary lesion at the time of baseline before the first administration of Lazertinib and the size of the primary lesion at the time of maximum overall response during Lazertinib administration.
Overall Survival (OS) Up to approximately 3 years Overall Survival (OS) is defined as the period from the start of Lazertinib administration to death from any cause.
