About this study

Official title: Resistance Mechanisms and Sequential Treatment Strategies Following First-Line Lorlatinib in ALK-Positive NSCLC: A Multi-center, Observational, Prospective Real-world Cohort Study (LORES)

This is a prospective, multicenter, non-interventional, single-arm, real-world study planned to be conducted in China, aimed at exploring the resistance mechanisms of first-line lorlatinib treatment in patients with ALK-positive locally advanced or metastatic NSCLC, as well as the efficacy and safety of sequential treatments following lorlatinib resistance in the real-world setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. mechanisms of resistance to first-line lorlatinib

    Reslstance Assessment

    1. Liquld Blops-Blood eIDNA NGS
    2. Tissue Biopsy (If applicablo)-NGS mechanisms of resistance to first-line lorlatinib
    3. Propression pattern
    • Priary ressstance
    • Acquined resistance
    1. Moleculsr mechanisms of progression via ctDNA/organize NGS testing.
    2. Difference between the mnechsnisins of primary and acquired resistance

    Measured: 24 months

Secondary outcomes (1)
  1. Exploring the sequential treatment strategies and their efficacy and safety after first-line progression with lorlatinib

    1. rwTTD1: discontinuation of lorlatinib for any reason (including disease progression, death, severe adverse events, or patient choice)
    2. rwTTD2: progression on first-line lorlatinib to discontinuation of the first sequential anti-tumor treatment for any reason (including disease progression, death, severe adverse events, or patient withdrawal from the study)
    3. rwORR2: the overall proportion of patients who achieve complete response (CR) and partial response (PR)
    4. rwDCR2: the overall proportion of patients who achieve complete response (CR), partial response (PR), and stable disease (SD)
    5. rwPFS2: progression on first-line lorlatinib to disease progression or death from any cause or last confirmed survival 6、1-year/2-year-rwPFS2 rate: he proportion of patients who remain progression-free within 1 year/2 years

    7、the overall proportion of patients who survive within 1 year/2 years 8、Exploration of the proportion and related reasons for dose adjustment

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of ALK-Positive NSCLC, run by Shanghai Chest Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 11 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Li Zi ming (18017321562, liziming1980@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

mechanisms of resistance to first-line lorlatinib (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2025.
