A Real World Study of Ensartinib in Advanced ALK-positive NSCLC

Peking Union Medical College Hospital490 enrolled

Overview

The primary objective of this study is to evaluate the efficacy and safety of Ensartinib in advanced ALK-positive non-small cell lung cancer, and the mechanisms of population pharmacokinetics and resistance to Ensartinib.

Participants will receive Ensartinib at 225 mg orally once a day (QD). Treatments will continue until disease progression, meeting one of treatment discontinuation criteria (eg, patient decision, adverse event, pregnancy). At the time of disease progression, participants will enter a survival follow-up until death, withdrawal of consent or study closure, whichever occurs earlier. Collection of venous blood sample from participants included 3 times: before treatment, 8 weeks of treatment, and disease progression. Blood specimens of 8 ml were collected each time for ctDNA NGS testing, and evaluation of Ensartinib population pharmacokinetics with blood sampling after 8 weeks.

Initially general blood tests including complete blood count, biochemistry, electrolytes, and urine biochemistry were performed as a routine screening in order to identify any abnormalities. 7.

Outcomes

Primary Outcomes

Progression free survival (PFS)

Defined as time from first dose of Ensartinib to disease progression or death due to any causes

Time frame: 36 months

Secondary Outcomes

The objective response rate (ORR)

ORR per RECIST 1.1 calculated as the proportion of patients with a best overall response defined as complete response (CR) or partial response (PR).

Time frame: 36 months

Overall survival (OS)

OS, defined as time from first dose of Ensartinib to death due to any cause

Time frame: 48 months

12 month/24 month/36 month/48 month-overall survival (OS) rate OS

Defined as the time from randomization to death from any cause. The OS rate was estimated based on the landmark analysis.

Time frame: 12 months，24 months，36 months，48 months

Incidence of patients experiencing adverse events (AE)

Adverse events are graded according to CTCAE 5.0

Time frame: 36 months
