Condition(s) targeted: Sjogren's Syndrome; Cough

Intervention: Dornase alfa (Drug); Saline (Drug)

Phase: Phase 1

Status: Withdrawn

Sponsored by: University of Connecticut Health Center

Official(s) and/or principal investigator(s):
Metersky L Mark, MD, Principal Investigator, Affiliation: University of CT Health Center

Summary

Patients with Sjogren's disease have destruction of the mucus secreting cells in the airway. This manifestation of the disease leads to the common complaint of persistent dry cough that is seen in many of these patients. This study is aimed at determining whether the regular use of Pulmozyme will result in decreased cough and improved quality of life.

Clinical Details

Official title: A Double-blind, Placebo-controlled Cross-over Trial of Pulmozyme for Sjogren's Associated Cough

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Supportive Care

Primary outcome: Changes in Leicester Cough Questionnaire (LCQ) score and cough visual analog scale.

Secondary outcome:

Change in spirometry, specifically FEV1, FVC, FEV1/FVC and FEF 25-75%

To determine the DNA content in sputum from patients with chronic cough due to Sjogren's disease.

To determine the safety of Pulmozyme, taken twice a day in patients with chronic cough due to Sjogren's disease.

Detailed description: Patients with Sjogren's disease have destruction of the mucus secreting cells in the bronchi. This manifestation of the disease leads to the common complaint of persistent dry cough that is seen in many of these patients. The investigators theorize that regular use of Pulmozyme will result in decreased cough and improved quality of life, by improving mucus clearance. Primary Objective: To determine if the use of Pulmozyme, twice a day improves cough-related quality of life or cough severity in patients with chronic cough due to Sjogren's disease. Secondary Objectives: 1. To determine the DNA content in sputum from patients with chronic cough due to Sjogren's disease. 2. To determine the effect of Pulmozyme use on pulmonary function in patients with chronic cough due to Sjogren's disease. 3. To determine the safety of Pulmozyme, taken twice a day in patients with chronic cough due to Sjogren's disease.
