A Study to Learn About Lorlatinib in Patients With Non-Small Cell Lung Cancer (NSCLC) Which Has Spread Out.

February 3, 2026 updated by: Pfizer

A Retrospective Study to Evaluate the Real-World Effectiveness of Lorlatinib Among ROS1-Positive NSCLC Patients

The purpose of this study is to learn about lorlatinib for the possible treatment of lung cancer which could not be controlled.

This study is seeking participants who:

  • have lung cancer that could not be controlled.
  • have a type of gene called a ROS proto-oncogene 1. A gene is a part of your DNA that has instructions for making things your body needs to work.
  • have received at least 1 treatment before.

All participants in this study had received lorlatinib. Lorlatinib is a tablet that is taken by mouth at home. They continued to take lorlatinib until their cancer was no longer responding. The study will look at the experiences of people receiving the study medicine. This will help to see if the study medicine is safe and effective.

Study Population

This is a retrospective, observational study to investigate effectiveness, treatment patterns, and gene mutation profile of ROS1-positive NSCLC patients who had received lorlatinib after any TKI treatment failure in Taiwan using an EMR database, NTUH-iMD. Study population consists of patients who were diagnosed with ROS1-positive NSCLC and received at least one dose of lorlatinib between 1st April, 2018, and 30th September, 2023 after any TKI treatment failure.

Description

Inclusion Criteria:

  1. Patients are aged 18 years or older on index date
  2. Patients have confirmed diagnosis of ROS1-positive NSCLC
  3. Patients have received at least one dose of lorlatinib between 1st April, 2018, and 30th September, 2023

Exclusion Criteria:

1. Patients participated in any clinical trials using lorlatinib during the observation period.

Index date is the date of the first dose of lorlatinib.

74 months from 1st April, 2018
The real world time to next treatment (rwTTNT)
Time Frame: 74 months from 1st April, 2018

Time to subsequent treatment or death, whichever occurs first, during observation period from index date will be summarized by the K-M plot with the corresponding 95% CI.

Index date is the date of the first dose of lorlatinib.

74 months from 1st April, 2018
The real world intracranial progression free survival (rwICPFS)
Time Frame: 74 months from 1st April, 2018

Time to real-world intracranial disease progression or death, whichever occurs first, during observation period from index date will be summarized by the K-M plot with the corresponding 95% CI.

Index date is the date of the first dose of lorlatinib.

74 months from 1st April, 2018

Secondary Outcome Measures

Outcome Measure

74 months from 1st April, 2018
Mean (SD), median (interquartile range, IQR), minimum and maximum value of duration of therapy (DoT) of lorlatinib
Time Frame: 74 months from 1st April, 2018

Time to real-world discontinuation of lorlatinib or death, whichever occurs first, during observation period from index date will be summarized by the K-M plot with the corresponding 95% CI.

Index date is the date of the first dose of lorlatinib.

74 months from 1st April, 2018
Number and proportion of patients receiving concomitant antihyperlipidemic agents
Time Frame: 74 months from index date; index date is the date of the first dose of lorlatinib
