Background: Lorlatinib is a potent third-generation ALK tyrosine kinase inhibitor (TKI). CROWN study demonstrated remarkable efficacy and manageable toxicity of first-line lorlatinib treatment for advanced non-small cell lung cancer (NSCLC) with ALK rearrangements. However, only 10 ALK-positive NSCLC patients were randomized to the lorlatinib group in China mainland. There is a vast vacancy of efficacy and safety regarding first-line lorlatinib treatment in China advanced ALK-positive NSCLC. Additionally, understanding of the benefit-risk profile of lorlatinib in a broader population and real-world data of diversity of ALK-TKIs are limited.
Patients And Methods: We adopted a patient-centric trial (PCT) design to provide more generalizable data to better inform clinical decision-making. This is a 3 cohorts, open-label, multicenter, phase II study (CTONG2203), conducted to prospectively enroll 189 treatment-naïve patients with advanced ALK-positive NSCLC in China, which was divided into 2 treatment intervention cohorts and real-world observing (RO) cohort. The treatment intervention cohorts include restrictive eligibility criteria "CROWN criteria (CC) cohort," and broadening eligibility criteria "Expand Eligibility Criteria (EC) cohort," who will receive first-line lorlatinib treatment. And we concomitantly set up a prospective RO cohort to observe the clinical outcomes of these patients treated with different ALK-TKI who received physician's therapy of choice.
Conclusion: This patient-centric study will contribute data on efficacy, safety and resistance mechanism of first-line lorlatinib, and offer better perspectives on the current status of real-world treatment of ALK-TKIs in advanced ALK-positive NSCLC in China.
Clinical Trial Registration: NCT06092086 (CTONG 2203).

Background: Alectinib, brigatinib, and lorlatinib are all preferred first-line (1L) therapies for anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) in National Comprehensive Cancer Network (NCCN) guidelines. Although clinical trials have demonstrated their efficacy, real-world evidence on treatment patterns, costs, and outcomes may help differentiate these therapies and inform optimal 1L treatment selection in the absence of head-to-head comparisons.
Objective: To evaluate real-world outcomes for patients with ALK+ NSCLC receiving 1L ALK tyrosine kinase inhibitors (TKIs), focusing on drug acquisition costs, health care utilization, and clinical outcomes.

The anaplastic lymphoma kinase () gene encodes a transmembrane receptor tyrosine kinase. Most mutations in gene result from translocations with other genes, forming fusion oncogenes. To date, 21 different genes have been identified as fusion partners, each activating distinct signaling pathways that influence cancer cell proliferation, invasiveness, and tumorigenicity.

Rationale: ROS1 rearrangement a distinct molecular subtype of non-small cell lung cancer that is amenable to targeted therapeutic interventions. Despite the availability of effective targeted therapies, the development of acquired resistance to later-line inhibitors, particularly lorlatinib, remains an inevitable, and clinically significant challenge. The emergence of the ROS1 L2086F mutation as a mechanism of lorlatinib resistance further complicates treatment, with limited therapeutic options available post-resistance.

Background: DNA-based next-generation sequencing (NGS) has identified ALK rearrangements in lung squamous cell carcinoma (LUSC), a subset of nonsmall cell lung cancer traditionally lacking effective targeted therapies. While ALK tyrosine kinase inhibitors (TKIs) like crizotinib and alectinib are effective in ALK-rearranged lung adenocarcinoma, their efficacy in LUSC remains poorly defined due to limited subtype-specific data.
Methods: We presented a case of ALK-rearranged LUSC and established a patient-derived xenograft (PDX) model to validate the tumor-inhibitory effects of various ALK-TKIs on ALK-positive LUSC.

Background: Lorlatinib, a third-generation Anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitors (TKI), has demonstrated excellent curative effect in clinical studies to overcome mutations resistant to first- and second-generation ALK-TKIs. It also has improved blood-brain barrier crossing and reduced brain metastases.
Methods: 44 patients were selected who received Lorlatinib as initial treatment for first-diagnosis ALK-positive non-small-cell lung cancer (NSCLC) or who received Lorlatinib as a back-line treatment after developing resistance with first- and second-generation ALK-TKIs.
