About this study
Official title: A Phase 2 Peri-Operative Trial of Fianlimab and Cemiplimab in Combination With Chemotherapy Versus Cemiplimab in Combination With Chemotherapy in Patients With Resectable Early Stage (Stage II to IIIB [N2]) NSCLC
This study is researching an experimental drug called fianlimab (also called REGN3767) with two other medications called cemiplimab and platinum-doublet chemotherapy, individually called a "study drug" or collectively called "study drugs", when combined in this study. The study is being conducted in patients who have resectable stage II to IIIB (N2) non-small cell lung cancer (NSCLC) that can be treated with surgery.
The aim of the study is to see how effective the combination of fianlimab, cemiplimab, and chemotherapy is in comparison with cemiplimab and chemotherapy as peri-operative therapy in participants with NSCLC.

The study is looking at several other research questions, including:
- What side effects may happen from taking the study drugs
- How much of each study drug is in the blood at different times
- Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects)
- How administering the study drugs might affect quality of life
- Conditions
- Resectable Non-small Cell Lung Cancer
- Being tested
- Fianlimab, Cemiplimab, Pemetrexed, Paclitaxel, Carboplatin
- Keywords
- Stage II to IIIB (N2), NSCLC, Neoadjuvant therapy, Subsequent adjuvant therapy, PeriOperative

Overall change in patient-reported global health status/QoL per European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)
EORTC-QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and single scales, including a global health status/quality of life (GHS/QoL) scale. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.
Measured: Up to 5 years

Measured: Up to 5 years
Overall change in patient-reported role functioning per EORTC QLQ-C30
Measured: Up to 5 years

The EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "Have you had pain in your chest?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in chest pain (EORTC QLQ-LC13 Item 40) score will be presented. A lower score indicates a better outcome.
Measured: Up to 5 years
Overall change in patient-reported dyspnea per EORTC QLQ-LC13
Measured: Up to 5 years
Overall change in patient-reported cough per EORTC QLQ-LC13
Measured: Up to 5 years

Measured: Up to 5 years
Change in patient-reported general health status per EuroQoL 5-Dimensional 5-Level Scale (EQ-5D-5L) index
The EQ-5D-5L descriptive system assesses 5 dimensions of health: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated on a 5-level scale: no problems, slight problems, moderate problems, severe problems and extreme problems
Measured: Up to 5 years
Change in patient-reported general health status per Visual analogue scale (VAS) scores
The EQ-5D-5L VAS records the respondent's self-rated health on a 10 centimeter (cm) vertical, visual analogue scale. It is rated by the respondent on a scale 0 to 100, with 0 being "the worst health you can imagine" and 100 being "the best health you can imagine".

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Fianlimab, Cemiplimab and Pemetrexed in people with Resectable Non-small Cell Lung Cancer, run by Regeneron Pharmaceuticals at 123 sites in 12 countries.
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 6 inclusion and 6 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 10 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 123 sites in Italy, Spain, Turkey (Türkiye), France, Georgia and 7 more countries. 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?
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?
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?
Pathological complete response (pCR) as evaluated by blinded independent pathological review (BIPR) in post-treatment resected tumor samples (time frame: Up to 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 10 Aug 2026.
