Phase II Study of the Safety and Efficacy of Inhaled Alpha-1 Antitrypsin (AAT ) in Cystic Fibrosis Patients

This study has been completed.

Cystic Fibrosis (CF) is an inherited disorder in which mucus-secreting glands in the lungs produce considerable quantity of thick, sticky secretions that clog the airways, promote bacterial growth and lead to chronic obstruction, inflammation and destruction of the airways.

The purpose of this study is to collect data about the resolution of the chronic inflammatory state in addition to assure the safety of the therapy in CF patients.

Condition Intervention Phase
Cystic Fibrosis
Drug: Aerosolized, human, plasma-derived Alpha-1 Antitrypsin
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Double-Blind, Randomized, Placebo-Controlled, Phase II Study of the Safety and Efficacy of Inhaled Alpha-1 Antitrypsin (AAT ) in Cystic Fibrosis Patients

Primary Outcome Measures:
  • Safety and airway inflammation [ Time Frame: days 1,7,14,21,28,35,42,49,56,63 ]

Secondary Outcome Measures:
  • Sputum microbiology, pulmonary function and serum CRP [ Time Frame: days 1,7,14,21,28,35,42,49,56,63 ]

Enrollment: 21
Study Start Date: September 2007
Study Completion Date: July 2008
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 80 mg/kg AAT inhaled
80 mg/kg AAT inhaled
Drug: Aerosolized, human, plasma-derived Alpha-1 Antitrypsin
Placebo Comparator: Placebo inhaled
Placebo inhaled
Drug: Aerosolized, human, plasma-derived Alpha-1 Antitrypsin

Detailed Description:

In CF patients the unregulated inflammatory response overwhelms the normal protease (elastase)/antiprotease (AAT) balance, leading to the accumulation of elastase in the lung, destruction of the lung architecture, severe pulmonary dysfunction, and ultimately death.

Administration of AAT is to address the elastase/antiprotease imbalance in order to prevent destruction of the lung tissue and reduce the inflammatory dysregulation that causes pulmonary dysfunction.
