Itepekimab, Matched placebo for test product clinical trials

A double-blinded extension study to evaluate the long-term safety and tolerability of itepekimab in adult participants with inadequately controlled chronic rhinosinusitis with nasal polyps (CRSwNP) who participated in either EFC18418 or EFC18419 clinical studies

This study is looking at the long-term safety of a new medicine, itepekimab, for adults with nose polyps and ongoing sinus problems. It's for people who were in earlier trials and helps us understand if the treatment is safe over time.
