Clinical
Data, Inc. (NASDAQ: CLDA), today announced results from two Phase I
studies of Stedivaze™ (apadenoson), which demonstrated that Stedivaze
was safe and well tolerated in patients with asthma and chronic
obstructive pulmonary disease (COPD). Stedivaze is a potent and highly
selective agonist of the adenosine A2A receptor subtype in
development as a pharmacologic stress agent for myocardial perfusion
imaging (MPI). Currently available adenosine agonists must be used with
caution or are contraindicated in patients with asthma and COPD. The
high selectivity of Stedivaze offers a potential advantage for the safe
use in this population, accounting for approximately 10 percent of the
7.6M MPI tests performed annually. The Company is also
actively enrolling patients in ASPECT 1, a Phase III trial designed to
demonstrate the safety and effectiveness of Stedivaze.
“The positive results from our preliminary studies in asthmatics and
COPD patients are encouraging and represent a milestone toward our goal
of developing a coronary vasodilator that is both safe and well
tolerated in these populations”
"The positive results from our preliminary studies in asthmatics and
COPD patients are encouraging and represent a milestone toward our goal
of developing a coronary vasodilator that is both safe and well
tolerated in these populations," said Carol R. Reed, M.D., Executive
Vice President and Chief Medical Officer of Clinical Data. "We intend to
expand these findings by initiating further safety studies of Stedivaze
in patients with asthma and COPD, while continuing to evaluate the
efficacy and potential for superior tolerability of Stedivaze in our
ongoing Phase III program."
In both of these placebo-controlled studies, Stedivaze was administered
as a single IV bolus, at the same dose utilized in the ASPECT 1 trial.
In 49 patients with mild to moderate asthma and 50 patients with
moderate to severe COPD, Stedivaze had no effects on pulmonary function
tests. Adverse events overall were similar in both incidence and
severity to the adverse event profile seen in previous studies of
Stedivaze in patients without lung disease, and continue to support its
potential for improved tolerability. Most frequently observed adverse
events, common to this class of agents, included palpitations, flushing,
chest discomfort and shortness of breath. Results of both of these
trials support the continued study of Stedivaze in patients with asthma
and COPD.
In addition to completing these Phase I studies, the Company is
continuing to enroll patients in its ASPECT 1 trial of Stedivaze, a
Phase III randomized, double blind, active control study initiated in
November 2009, which is designed to demonstrate both efficacy and the
potential for improved tolerability for Stedivaze in patients undergoing
SPECT MPI. ASPECT 2, a second Phase III trial similar in design to
ASPECT 1, is expected to begin in the second half 2010.
