Safety and Tolerability Trial of Inhaled Alpha1-Proteinase Inhibitor (Human), Hydrophobic Chromatography Process (Alpha-1 HC) in Subjects With Cystic Fibrosis

11. januar 2016 oppdatert av: Grifols Therapeutics LLC

A Three Week Dose Escalation, Randomized, Double-Blind, Placebo-Controlled Trial to Assess the Safety and Tolerability of 100 mg or 200 mg of Inhaled Alpha-1 HC, Once a Day in Subjects With Cystic Fibrosis.

This was a randomized, double-blind, placebo-controlled, dose escalation study to assess the safety and tolerability of 100 mg and 200 mg of inhaled Alpha-1 HC administered once a day for three weeks in subjects aged 18 years and older with cystic fibrosis (CF). The treatment duration in this study was intended to provide multi-dose safety information prior to proceeding to longer durations of exposure.

Beskrivelse

Inclusion Criteria:

  • Age 18 years or older.
  • Documentation of CF diagnosis.
  • Have a pre-bronchodilator FEV1 ≥ 40% of predicted at Visit 1 and have a Visit 2 pre-investigational product FEV1 that is ≥ 40% of predicted and within ± 15% of the Visit 1 result.
  • Deemed by the Investigator to be a suitable candidate for serial collection of expectorated sputum.

Exclusion Criteria:

  • Had a pulmonary exacerbation during the 4 weeks before screening (Visit 1) which required the initiation of new antibiotic treatment
  • Have a pulmonary exacerbation during the screening period (between Visit 1 and Visit 2) which requires the initiation of new antibiotic treatment
  • FEV1 < 0.59 liters at the screening visit
  • Respiratory insufficiency with continuous supplemental oxygen therapy, or carbon dioxide retention
  • Elevated aspartate transaminase (AST) or alanine aminotransferase (ALT) that is ≥ 3 times the upper limit of normal for age and gender
  • Smoking during the past 6 months
  • Lung surgery during the past 2 years
  • Positive culture for Burkholderia cepacia or mycobacterium during the past two years.
  • Active allergic bronchopulmonary aspergillosis
  • Pre-treatment sputum collection at Visit 1 or Visit 2 (Randomization) characterized by problems such as inadequate sputum volume or quality.
  • Known selective Immunoglobulin A (IgA) deficiency with known antibody against IgA (anti-IgA antibody).
  • History of anaphylaxis or severe systemic response to any plasma-derived alpha1-proteinase inhibitor preparation or other blood product(s), or to polysorbates.
  • Use of chronic oral steroids during the study. Note: Inhaled corticosteroids that had been administered for at least 4 weeks prior to Visit 1 were permissible during the study.
  • Use of chronic, high dose ibuprofen therapy within 3 weeks of screening and at anytime during the study.
  • Chronic maintenance therapy with systemic antibiotics within 3 weeks of screening and through last dose of investigational product.
  • Use of leukotriene synthesis inhibitor (zileuton) or leukotriene receptor antagonists (montelukast, zafirlukast) within 3 weeks of screening and at anytime during the study.
  • Use of roflumilast within 3 weeks of screening and at any time during the study.
  • Initiation of a new chronic medication or dosage change of a chronic medication for treatment of cystic fibrosis (example: Kalydeco™ [ivacaftor]) within 3 weeks of screening (Visit 1).
