NCT01357447

  Purpose

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.

Primary Outcome Measures:
  • Changes in Leicester Cough Questionnaire (LCQ) score and cough visual analog scale. [ Time Frame: After 2 weeks of therapy. ] [ Designated as safety issue: No ]
    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 Outcome Measures:
  • Change in spirometry, specifically FEV1, FVC, FEV1/FVC and FEF 25-75% [ Time Frame: After 2 weeeks of therapy ] [ Designated as safety issue: No ]
    Changes in pulmonary function in study subjects with use of pulmozyme will be determined by measuring specific spirometric indices (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. [ Time Frame: At start of study ] [ Designated as safety issue: No ]
    Sputum from patients with chronic cough due to Sjogren's disease will be analyzed to determine the DNA content at the start of the study.

  • To determine the safety of Pulmozyme, taken twice a day in patients with chronic cough due to Sjogren's disease. [ Time Frame: After 2 weeks of therapy. ] [ Designated as safety issue: No ]
    Adverse reactions, if any, due to use of Pulmozyme, taken twice a day in study patients, will be determined.

Dornase alfa is a highly purified solution of recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA.
Drug: Saline
2.5 ml via nebuliser BID for 2 weeks (alternating with study drug)
Placebo Comparator: Saline
Normal saline 0.9% solution
Drug: Dornase alfa
Dose: 2.5 mg solution BID via nebuliser for 2 weeks
Other Name: Pulmozyme
Drug: Saline
2.5 ml via nebuliser BID for 2 weeks (alternating with study drug)

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.
