Further study details as provided by Acusphere:

Primary Outcome Measures:
  • To determine the safety of AI-700 in patients with diminished pulmonary diffusing capacity (DLCO) and moderate or severe COPD and/or CHF
  • To determine the pharmacokinetics of perfluorocarbon gas in blood following an intravenous injection of AI-700 in this patient population

Study Start Date: August 2004
Estimated Study Completion Date: July 2005
Detailed Description:
In ongoing clinical trials, AI-700 is currently being evaluated for its value to provide enhanced echocardiography to detect CAD. The patient population is comprised of those patients who have chest pain and are being evaluated for inducible ischemia. This population may include patients with compromised pulmonary function due to COPD or CHF. This study was to evaluate the safety of AI-700 in these patients.
