Cemiplimab and Fianlimab Before Surgery for the Treatment of Stage IB-IIIB Non-Small Cell Lung Cancer

Launched by MAYO CLINIC · Apr 7, 2025

ClinConnect Summary

This clinical trial is looking at how effective a combination of two medications, cemiplimab and fianlimab, is when given to patients with certain stages of non-small cell lung cancer (NSCLC) before they have surgery. The trial aims to see if this approach can help shrink the tumors more than the current standard treatment, which usually involves chemotherapy and immunotherapy. The researchers hope that by using these medications, the body’s immune system can better fight the cancer.

To participate in the trial, patients need to be at least 18 years old and have been diagnosed with stage IB to IIIB NSCLC. They must be able to have their tumors surgically removed, and their cancer must express a specific protein called PD-L1. Other health criteria, like having good lung function and blood counts, are also important for eligibility. If someone joins the trial, they will receive the medications before their surgery and be closely monitored by the study team. It’s important to note that this trial is still in the planning stages and has not yet started recruiting participants.

• • Calculated creatinine clearance ≥ 45 ml/min using the Chronic Kidney Disease Epidemiology (CKD-EPI) Creatinine Equation (obtained ≤ 15 days prior to registration)
• • Negative pregnancy test done ≤ 8 days prior to registration, for persons of childbearing potential only
• • Provide written informed consent
• • Willingness to provide mandatory blood specimens for correlative research
• • Willingness to provide mandatory tissue specimens for correlative research
• • Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)
• Exclusion Criteria:
• * Any of the following because this study involves an investigational agent, the genotoxic, mutagenic, and teratogenic effects of which on the developing fetus and newborn are unknown:
• • Pregnant persons
• • Nursing persons
• • Persons of childbearing potential or able to father a child who are unwilling to employ highly effective contraception during the study and up to 6 months after the last dose
• • Presence of targetable alterations \[Epiderman Growth Factor Receptor (EGFR), anaplastic lymphoma kinase (ALK), receptor tyrosine kinase (ROS1)\] in tumor
• • Unresectable or metastatic disease
• * Active or history of the following:
• • Prior systemic anti-cancer therapy or radiation therapy for the same cancer being studied in this protocol
• • Interstitial lung disease (e.g., idiopathic pulmonary fibrosis or organizing pneumonia), or active, noninfectious pneumonitis that required immune-suppressive doses of glucocorticoids to assist with management, or pneumonitis within the last 5 years
• • Autoimmune disease (including any history of inflammatory bowel disease)
• • Any syndrome that required systemic steroids or immunosuppressive medications EXCEPTIONS: patients with vitiligo; resolved childhood asthma/atopy; residual hypothyroidism that requires only hormone replacement; or psoriasis not requiring systemic treatment, type-1 diabetes mellitus, or rheumatoid arthritis managed without disease modifying anti-rheumatic drugs or \>10 mg prednisone equivalent
• • Patients requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications ≤14 days prior to registration.
• • NOTE: Inhaled or topical steroids and adrenal replacement doses \< 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
• • Patients with organ transplantation
• • History of myocardial infarction ≤ 6 months prior to registration, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias; or prior immune-related myocarditis
• * Uncontrolled intercurrent non-cardiac illness including, but not limited to:
• • Ongoing or active infection
• • Psychiatric illness/social situations Dyspnea at rest due to complications of advanced malignancy or other disease that requires continuous oxygen therapy
• • Any other conditions that would limit compliance with study requirements
• • Uncontrolled infection with HIV, hepatitis B virus (HBV), or hepatitis C virus (HCV) or diagnosis of immunodeficiency that is related to, or results in chronic infection.
• • Note: No testing is required for this study unless mandated by local health authority.
• EXCEPTIONS:
• • Patients with known HIV who have controlled infection \[undetectable viral load and cluster of differentiation 4 (CD4) count above 350 either spontaneously or on a stable antiviral regimen\] are permitted. For patients with controlled HIV infection, monitoring will be performed per local standards.
• • Patients with known hepatitis B (hepatitis B surface antigen positive \[HBsAg+\]) who have controlled infection (serum hepatitis B virus DNA polymerase chain reaction (PCR) that is below the limit of detection AND receiving anti-viral therapy for hepatitis B) are permitted. Patients with controlled infections must undergo periodic monitoring of HBV DNA per local standards and must remain on anti-viral therapy for at least 6 months beyond the last dose of investigational study drug.
• • Patients who are known hepatitis C virus antibody positive (HCV Ab+) who have controlled infection (undetectable HCV ribonucleic acid (RNA) by PCR either spontaneously or in response to a successful prior course of anti-HCV therapy) are permitted.
• • Patients with HIV or hepatitis must be reviewed by a qualified specialist (e.g., infectious disease or hepatologist) managing this disease prior to commencing and regularly throughout the duration of their participation in the trial NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial
