Non-small Cell Lung Cancer

Brief summary

This study is focused on patients with non-small cell lung cancer (NSCLC) and have been prescribed a cemiplimab (Libtayo®) based treatment regimen under standard care. The goal of this study is to learn more about the use, benefits, and safety of cemiplimab based treatment regimens in participants with NSCLC.

Detailed description

Originally registered as OBS17104 by Sanofi; transitioned to REGN 05Jul2023. The recruitment period will be 48 months. Data will be collected during routine clinical visits approximately every three months while the patient is on cemiplimab treatment and then approximately every six months for up to 24 months after cemiplimab discontinuation. Patients will be followed from cemiplimab treatment initiation until death, loss to follow-up, study withdrawal, or to the end of the study period (72 months after study launch), whichever occurs first.

Design outcomes

Primary

MeasureTime frameDescription
Overall survival (OS)Up to 72 monthsDate and primary cause of death

Secondary

MeasureTime frameDescription
Overall Response Rate (ORR)Up to 72 monthsDefined as the proportion of patients with a complete response or partial as the physician-reported best overall response.
Duration of Response (DoR)Up to 72 monthsDefined among responders (patients with a complete response or partial response) as the time from the date of the first response after cemiplimab treatment initiation until the first date of disease progression or death due to any cause.
Time to Response (TTR)Up to 72 monthsDefined as the time from the first cemiplimab dose until the date of first response observed for that patient. Patients who die during the study will be censored using the date of the last valid disease assessment).
Progression-Free Survival (PFS)Up to 72 monthsDefined as the time from the first dose of cemiplimab until the date of the first documented tumour progression or death due to any cause.
Time to first subsequent anti-NSCLC treatment (TTST)Up to 72 monthsDefined as the time from the first cemiplimab dose until the date of the first subsequent anti-NSCLC treatment.
Incidence of treatment-related adverse events (TR-AEs) in patients with advanced NSCLC treated with a cemiplimab-based regimen in routine clinical practiceUp to 72 monthsNumber of patients with treatment related adverse events occurring during treatment
Incidence of treatment-related serious adverse events (TR-SAEs) in patients with advanced NSCLC treated with a cemiplimab-based regimen in routine clinical practiceUp to 72 monthsNumber of patients with serious treatment related adverse events occurring during treatment
Incidence and severity of immune-mediated adverse events (imAEs) in patients with advanced NSCLC treated with a cemiplimab-based regimen in routine clinical practiceUp to 72 monthsNumber of patients with immune-mediated adverse events and serious immune-mediated adverse events occurring during treatment
Incidence and severity of infusion related reactions (IRRs) in patients with advanced NSCLC treated with a cemiplimab-based regimen in routine clinical practiceUp to 72 monthsNumber of patients with infusion related reactions and serious infusion related reactions adverse events occurring during treatment
