Allergic, Nonallergic Rhinitis Guidances Out
FDA has published guidances to assist sponsors in developing products to treat allergic and nonallergic rhinitis. Allergic Rhinitis: Developing Drug Products for Treatment addresses issues of trial design, effectiveness, and safety for new products being developed to treat seasonal allergic rhinitis and perennial allergic rhinitis. The document says its recommendations are based on an assessment of important issues raised in the review of both adult and pediatric allergic rhinitis clinical trials and FDA’s current understanding of the mechanism of the two related disorders. It does not contain discussion of the general issues of statistical analysis or clinical trial design. The guidance includes an Introduction, Background, Overall Considerations – Adult Program, Overall Considerations – Pediatric Program, Protocol Issues and Elements, Dated Analysis Issues, and Fixed-Dose Combination Products.
The second guidance, Nonallergic Rhinitis: Developing Drug Products for Treatment, discusses issues regarding the definition of a clinical phenotype, trial design, efficacy, and safety for new drug products under development. In particular, it addresses development programs for treating vasomotor rhinitis, a subtype of nonallergic rhinitis. It includes an Introduction, Background, General Considerations for Development, and Considerations for Pediatric Development.
