Treatment of Olfactory Dysfunction in Seasonal Allergic Rhinitis

This study has been terminated.

People with allergies frequently complain of a loss or reduction in the sense of smell.

In this study, the investigators propose to perform a randomized, double blind, placebo controlled parallel study of subjects with nasal allergies and decreased smell to determine the effect of a treatment for allergies on the sense of smell.

Condition Intervention Phase
Seasonal Allergic Rhinitis Drug: Mometasone Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Treatment of Olfactory Dysfunction in Seasonal Allergic Rhinitis

Further study details as provided by University of Chicago:

Primary Outcome Measures:
  • Histological Findings [ Time Frame: 2 weeks ]
    Number of eosinophils per high-powered field (HPF) in olfactory biopsy taken after 2 weeks of study treatment (higher values indicate greater inflammation); average of three HPF reported

Secondary Outcome Measures:
  • Change From Baseline in Total Nasal Symptom Score at 2 Weeks [ Time Frame: baseline and 2 weeks ]
    A decrease in scores between visits signifies an improvement in nasal symptoms. The total nasal symptom score can range from 0 to 27.

  • Change From Baseline in Nasal Peak Inspiratory Flow at 2 Weeks [ Time Frame: baseline and 2 weeks ]
    An increase between visits indicates improved nasal airflow.

  • Change From Baseline in Percentage of Eosinophils at 2 Weeks [ Time Frame: baseline and 2 weeks ]

    A decrease between visits signifies a reduction in inflammation.

    Calculated from cytology specimens obtained by lavage.
