Data Presented at the 2008 International Conference of the American
Thoracic Society
TORONTO, May 20 /PRNewswire-FirstCall/ -- Forest Laboratories, Inc. and Laboratorios Almirall, S.A. today presented results from four clinical trials assessing the efficacy and safety of aclidinium bromide, an investigational treatment for chronic obstructive pulmonary disease (COPD). Data from four preclinical studies further describing the properties of aclidinium were also presented at the meeting.

Presentations included data from a 464-patient randomized,
double-blind, four-week, Phase IIb study that evaluated both the efficacy
and tolerability of once-daily aclidinium (25 mcg, 50 mcg, 100 mcg, 200 mcg
or 400 mcg) or placebo in patients with moderate to severe COPD. An
open-label tiotropium (18 mcg) arm was included as an active control. The
study demonstrated aclidinium (200 mcg and 400 mcg), administered via a
multi-dose dry powder inhaler, significantly increased trough (24-hour)
forced expiratory volume in one second (FEV1) -- an important measure of
lung function -- on Day 29 compared with placebo (p<0.05 vs placebo). There
was a dose response observed for lung function improvement with once-daily
aclidinium. Aclidinium was well tolerated, with no dose-dependent effect on
ECG, laboratory parameters, or adverse events. Overall, the most frequently
reported adverse events were headache (4.1% of patients), dry mouth (2.8%
of patients), exacerbation of chronic obstructive airways disease (1.7% of
patients) and cough (1.7% of patients). Based on these results, aclidinium
200 mcg administered once every 24 hours was selected as the dose for
investigation in the two ongoing Phase III clinical trials, ACCLAIM COPD I
and II, which are expected to report out during the second ha
