The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
This study will assess and compare the safety and tolerability of inhaled TPI 1020 (repeated nominal doses; 500 μg BID x 6 weeks) versus inhaled budesonide (repeated doses; 800 μg BID x 6 weeks) and a matching placebo. Pharmacodynamic (PD) activity on FEV1, sputum and blood cells and cytokines will also be studied.

Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

Further study details as provided by Pharmaxis:

Primary Outcome Measures:
  • To determine the airway specific, and general safety and the tolerability of inhaled TPI 1020 administered via Aerolizer™ in COPD patients. • To assess the effects of TPI 1020 versus those of budesonide on sputum neutrophil counts on Days 0 and 42. [ Time Frame: 42 days ]

Secondary Outcome Measures:
  • Sputum neutrophil counts on Days 0 and 21. • Trough FEV1, SVC and IC on Days 0, 21 and on Day 42. • eNO levels on Days 0, 21 and on Day 42. [ Time Frame: 42 days ]

Detailed Description:
A multi-centre, randomized, placebo and active-controlled, 6-week study of inhaled TPI 1020, inhaled budesonide or matching placebo (random allocation of eligible patients to the three treatments at a ratio of 3:3:1), to evaluate the safety, tolerability and pharmacodynamic activity of TPI 1020 in 42 evaluable COPD subjects.
