About this study
Official title: Randomized Phase II Study of Pembrolizumab 200mg every12 Weeks Versus Every 3 Weeks in NSCLC With Clinical Benefit to Pembrolizumab Monotherapy: Multicenter International Study
This phase II trial studies how well pembrolizumab given every 12 weeks works compared to every 3 weeks in treating patients with non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab every 12 weeks may provide similar disease control with fewer treatments for patients with non-small cell lung cancer when compared to every 3 weeks. Demonstrating that 12 week dosing is as effective as 3 week dosing may also have a significant impact when considering the cost required for these medications.
Read the detailed description
PRIMARY OBJECTIVES:
- To evaluate the 1-year progression-free survival rate with 200mg pembrolizumab administered every 3 weeks compared to 200mg pembrolizumab administered every 12 weeks.
SECONDARY OBJECTIVES:
- To assess overall survival between the two treatment groups. II. To assess the serious adverse event profiles between the two treatment groups.
EXPLORATORY OBJECTIVES:
- To evaluate circulating biomarkers of treatment response and resistance. II. To characterize fecal microbiotic profile and to correlate those results with tumor characteristics and antitumor immune responses.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive pembrolizumab intravenously (IV) over 30 minutes every 3 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive pembrolizumab IV over 30 minutes every 12 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, and then every 12 weeks for at least 12 months.

| Study group | Role | What they receive |
|---|---|---|
| Arm I (200mg pembrolizumab 3 weeks) | Active comparator | Patients receive 200mg pembrolizumab IV over 30 minutes every 3 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity. Receives: Biological: Pembrolizumab |

What is being measured
The primary outcome is the main question the study is designed to answer.
1-year Progression-free Survival (PFS)
Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
Measured: 12 months from the start of first cycle of standard dose-schedule of pembrolizumab treatment
Secondary outcomes (2)
Overall Survival
Defined as the number of months between Loading Phase enrollment and death from any cause. Analysis of overall survival between the two treatment groups will be carried forth using a log-rank test accounting for the stratification factors, including other known variables such as PD-L1 tumor proportion score, line of therapy, histology, mutation profile.
Measured: 12 months after treatment completion to up to 62 months.
Incidence of Adverse Events
Assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Will be assessed through the evaluation of grade 3 or higher toxicities deemed possibly related to treatment. Both efficacy and toxicity rates will be estimated using simple relative frequencies. The corresponding 95% confidence intervals for the estimated probabilities will be computed.
Measured: Up to 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Pembrolizumab in people with Lung Non-Small Cell Carcinoma, run by Roswell Park Cancer Institute at 1 site in United States.
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 13 inclusion and 13 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: under way, not looking for participants, as of the sponsor's last update on 22 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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 21 Sep 2026). 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?
1-year Progression-free Survival (PFS) (time frame: 12 months from the start of first cycle of standard dose-schedule of pembrolizumab treatment). 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 22 Oct 2026.
