Inspiration and Exasperation: The Challenges of Inhaled Biologics

Hall, Peter and Vahle, John and Colman, Karyn (2021) Inspiration and Exasperation: The Challenges of Inhaled Biologics. Toxicologic Pathology. ISSN 15331601

Abstract

The delivery of biotherapeutic molecules (antibodies, proteins, peptides) and nucleic acids via the respiratory route has presented challenges for regulatory approval, due in part to a lack of understanding of the expected pathology, mechanisms of toxicity, and immunogenicity induced by the inhalation route. Although the first inhaled biotherapeutic was approved some time ago (Dornase Alfa, Pulmozyme; Genetech, 1993), no other inhaled biotherapeutics have been marketed for the treatment of human disease other than the inhaled insulins (Exubera; Pfizer, 2006 and Afrezza; Mannkind Corporation, 2014). As a result, scientific knowledge within the toxicologic pathology community is fragmented with precious little publicly available data. Therefore, one of the aims of this special edition was to generate a collection of manuscripts that pathologists and toxicologists could refer in order to understand the pathology, mechanisms of toxicity, immunogenicity, and challenges associated with the development of inhaled biotherapeutics.
