Fianlimab + Cemiplimab + Chemotherapy for Non-Small Cell Lung Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines the effectiveness of a new treatment combination for people with advanced non-small cell lung cancer (NSCLC). It tests fianlimab (an experimental drug) with cemiplimab and chemotherapy to determine if this combination is more effective than cemiplimab with chemotherapy alone. Researchers also assess any side effects and potential improvements in quality of life. Individuals with advanced NSCLC who have not received other treatments for their condition may be suitable candidates for this trial. As a Phase 2, Phase 3 trial, this research evaluates the treatment's effectiveness in a smaller group and represents the final step before FDA approval, providing patients access to potentially groundbreaking therapy.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on corticosteroid therapy or have received certain systemic therapies recently, you may need to adjust or stop those before joining the trial. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the combination of fianlimab, cemiplimab, and chemotherapy is under study for safety and effectiveness in treating advanced non-small cell lung cancer (NSCLC). Previous studies have found that cemiplimab with chemotherapy can extend patient survival and is generally well-tolerated. Most side effects were manageable, though some patients experienced low blood cell counts, tiredness, and nausea.
Less information exists about fianlimab because it remains under investigation. However, in current trials testing fianlimab with cemiplimab and chemotherapy, researchers closely monitor safety. Early results suggest that this combination might have side effects similar to those seen with cemiplimab and chemotherapy alone.
The studies are in advanced stages, indicating that earlier research has shown a reasonable safety profile. This suggests that while side effects are possible, they are being carefully studied and managed.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the potential of combining fianlimab and cemiplimab with chemotherapy for non-small cell lung cancer (NSCLC) because these treatments have unique mechanisms that may enhance effectiveness. Unlike traditional treatments that primarily focus on chemotherapy alone, fianlimab and cemiplimab are immunotherapies that boost the body's immune response to target and kill cancer cells more effectively. Fianlimab is a novel anti-LAG-3 antibody, while cemiplimab is an anti-PD-1 antibody, both of which work by unleashing the immune system to better recognize and attack cancer cells. This combination could potentially offer a more powerful and targeted attack against NSCLC, potentially improving outcomes compared to standard chemotherapy regimens.
What evidence suggests that this trial's treatments could be effective for advanced non-small cell lung cancer?
Research has shown that combining cemiplimab with a type of chemotherapy called platinum-doublet yields promising results for treating advanced non-small cell lung cancer (NSCLC). Studies have found that this combination can significantly increase survival rates. Specifically, patients receiving cemiplimab and chemotherapy more than doubled their chances of surviving five years compared to those who did not receive this combination.
In this trial, some participants will receive cemiplimab with platinum-doublet chemotherapy, while others will receive an additional treatment with fianlimab. Research on fianlimab is ongoing, as it uniquely helps the immune system fight cancer cells more effectively. Early results suggest that adding fianlimab to the cemiplimab and chemotherapy treatment may enhance its effectiveness. However, further research is needed to confirm these initial findings.12456Who Is on the Research Team?

Are You a Good Fit for This Trial?
Adults with advanced non-small cell lung cancer (NSCLC) who haven't had systemic treatment for recurrent or metastatic NSCLC. They must have a performance status ≤1, indicating they are relatively active and can care for themselves. Participants need to have measurable lung cancer lesions and adequate organ function. Those with certain gene mutations, recent immune suppression treatments, untreated brain metastases, significant autoimmune disease, or prior specific therapies are excluded.Inclusion Criteria

Trial Overview
The trial is testing the effectiveness of fianlimab combined with cemiplimab and chemotherapy versus just cemiplimab and chemotherapy in treating advanced NSCLC. It will also examine side effects, drug levels in blood over time, potential antibody development against the drugs, and any impact on quality of life.
