What is being measured

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

  1. Percentage of Participants With Objective Response (Cohort 1)

    Objective response rate (ORR) was defined as the percentage of participants with a best overall confirmed response of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumor (RECIST) version 1.1 relative to the total participants in the analysis population. CR was defined as the disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (<) 10 millimeter (mm). PR was defined as a greater than equal to (>=) 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Independent Central Radiology (ICR) was used for disease progression assessment.

    Measured: From Cycle 1 Day 1 to documented progression of disease by ICR (up to 67 weeks)

  22. Steady-State Cmax

    The loratinib Cmax was estimated using non-compartmental analysis. Steady-state was reached on Cycle 1 Day 15.

    Measured: At Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, and 24 hours on Day 15 of Cycle 1

  23. Steady-State Tmax

    The loratinib Tmax was estimated using non-compartmental analysis. Steady-state was reached on Cycle 1 Day 15.

    Measured: At Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, and 24 hours on Day 15 of Cycle 1

  24. Steady-State AUCtau

    The loratinib AUCtau was estimated using non-compartmental analysis. Steady-state was reached on Cycle 1 Day 15.

    Measured: At Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, and 24 hours on Day 15 of Cycle 1

  25. Apparent Clearance (CL/F)

    The loratinib CL/F was estimated using non-compartmental analysis. Steady-state was reached on Cycle 1 Day 15.

    Measured: At Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, and 24 hours on Day 15 of Cycle 1

  26. Observed Accumulation Ratio (Rac)

    The loratinib Rac was estimated using non-compartmental analysis. Steady-state was reached on Cycle 1 Day 15.

    Measured: At Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, and 24 hours on Day 15 of Cycle 1

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lorlatinib in people with Carcinoma, Non-Small-Cell Lung, run by Pfizer at 21 sites in China.

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 29 inclusion and 29 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: finished, as of the sponsor's last update on 5 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Oct 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Objective Response (Cohort 1) (time frame: From Cycle 1 Day 1 to documented progression of disease by ICR (up to 67 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03909971, which also lists 2 linked publications.

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 5 Nov 2025.
