What Is NDC 47781-0335?
NDC 47781-0335 refers to a specific drug identified in the National Drug Code system, with its unique code assigned to a branded or generic pharmaceutical. To provide precise insights, the drug in question must be verified, but as of the latest available databases, NDC 47781-0335 corresponds to Tezspire (tezepelumab-ekko), marketed by AstraZeneca, approved by the FDA in December 2021 for severe asthma.
Market Landscape
Product Overview
Tezspire (tezepelumab-ekko) is a monoclonal antibody targeting thymic stromal lymphopoietin (TSLP). It is used for:
- Add-on therapy in severe asthma
- Patients aged 18 and older
- Approved following Phase III trials demonstrating efficacy in reducing asthma exacerbations
Market Drivers
- Rising prevalence of severe asthma worldwide
- Limited existing biologics targeting TSLP (e.g., only AstraZeneca’s Tezspire and Amgen's potential competitors)
- Growing acceptance of biologic therapies among pulmonologists and allergists
