A Study to Learn if a Combination of Fianlimab and Cemiplimab Versus Cemiplimab Alone is More Effective for Adult Participants With Advanced Non-Small Cell Lung Cancer (NSCLC)
Study Details
Study Description
Brief Summary
The study is researching an experimental drug called fianlimab (also called REGN3767), combined with a medication called cemiplimab (also called REGN2810), individually called a "study drug" or collectively called "study drugs" in this form. The study is focused on patients who have advanced non-small cell lung cancer (NSCLC).
The aim of the study is to see how effective the combination of fianlimab and cemiplimab is in treating advanced NSCLC, in comparison with cemiplimab by itself.
The study is looking at several other research questions, including:
-
What side effects may happen from taking the study drugs
-
How much study drug is in your blood at different times
-
Whether the body makes antibodies against the study drugs (which could make the drug less effective or could lead to side effects)
-
How administering the study drugs might improve your quality of life

Outcome Measures
Primary Outcome Measures
- Objective response rate (ORR) as assessed by blinded independent central review (BICR), using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) [Up to 136 weeks]
Phase 2 and Phase 3 Proportion of patients with a best overall response of confirmed complete response (CR) or partial response (PR)
- Overall survival (OS) [Up to 5 years]
Phase 3 The time from randomization to the date of death due to any cause
Secondary Outcome Measures
- Incidence of treatment-emergent adverse events (TEAEs) [Up to 136 weeks]
Phase 2 and Phase 3 A TEAE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment

Patients are eligible if central nervous system (CNS) metastases are adequately treated and patients have neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 2 weeks prior to enrollment. Patients must be off (immunosuppressive doses of) corticosteroid therapy.
-
Patients with tumors tested positive for epidermal growth factor receptor (EGFR) gene mutations, anaplastic lymphoma kinase (ALK) gene translocations, or c-ros oncogene 1 (ROS1) fusions. All patients will have tumor evaluated for EGFR mutations, ALK rearrangement, and ROS1 fusions confirmed by a central laboratory when local laboratory results are not available.
-
Encephalitis, meningitis, or uncontrolled seizures in the year prior to enrollment.
-
History of interstitial lung disease (eg, idiopathic pulmonary fibrosis or organizing pneumonia), of active, noninfectious pneumonitis that required immune-suppressive doses of glucocorticoids to assist with management, or of pneumonitis within the last 5 years. A history of radiation pneumonitis in the radiation field is permitted as long as pneumonitis resolved ≥6 months prior to enrollment.
-
Known primary immunodeficiencies, either cellular (eg, DiGeorge syndrome, T-cell-negative severe combined immunodeficiency [SCID]) or combined T- and B-cell immunodeficiencies (eg, T- and B-cell negative SCID, Wiskott Aldrich syndrome, ataxia telangiectasia, common variable immunodeficiency).
-
Ongoing or recent (within 2 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk of immune-mediated treatment-emergent adverse events (imTEAEs). Patients with uncontrolled type 1 diabetes mellitus or with uncontrolled adrenal insufficiency are excluded. The following are not exclusionary: vitiligo, childhood asthma that has resolved, residual hypothyroidism that required only hormone replacement, or psoriasis that does not require systemic treatment.

Physiologic replacement doses are allowed even if they are >10 mg of prednisone/day or equivalent, as long as they are not being administered for immunosuppressive intent. Patients with clinically relevant systemic immune suppression within the last 3 months before trial enrollment are excluded. Inhaled or topical steroids are permitted, provided that they are not for treatment of an autoimmune disorder.
-
Patients who have received prior systemic therapies are excluded with the exception of the following:
-
Adjuvant or neoadjuvant platinum-based doublet chemotherapy (after surgery and/or radiation therapy) if recurrent or metastatic disease develops more than 6 months after completing therapy as long as toxicities have resolved to CTCAE grade ≤1 or baseline with the exception of alopecia and peripheral neuropathy.
-
Anti-PD-L1 with or without LAG-3 as an adjuvant or neoadjuvant therapy as long as the last dose is >12 months prior to enrollment.
