Details and patient eligibility

About

This is a phase II randomized, double-blinded, placebo-controlled study to evaluate the efficacy of topical intranasal treatment of beclomethasone vs. placebo for improved olfactory function.

Full description

Eligible participants are randomized to receive either Beclomethasone or placebo intranasally via a microsponge twice on day 1 and day 14. Study duration is three months and includes 4 in-person study visits: 2 visits for drug administration at Baseline and Week 2, and 2 follow-up visits at Week 6 and Week 18. Participants will be expected to complete the Smell Identification Test (SIT) and Questionnaire on Olfactory Disorders (QOD) at baseline, Week 6, and Week 18. The investigator hypothesizes that the application of beclomethasone directly in the nasal cavity will result in improved olfactory function.
