Capstone Therapeutics Announces Update to Timing of Release of Final Results From AZX100 Phase 2a Pilot Clinical Trial in Surgical (Trocar Site) Scarring

/ Source: GlobeNewswire

TEMPE, Ariz., April 4, 2011 (GLOBE NEWSWIRE) -- Capstone Therapeutics (Nasdaq:CAPS) (the "Company") today announced an update to the reporting schedule for twelve-month results from its AZX100 Phase 2a pilot clinical trial in surgical (trocar site) scarring.

Due to the size and complexity of the dataset, the report has been delayed beyond the Company's originally-projected end-of-first quarter 2011 announcement date.

The Company will report these results as soon as practicable.

AZX100 Phase 2a in Surgical (Trocar Site) Scarring

Study Description

The Company conducted a pilot Phase 2a clinical trial of AZX100 in surgical (trocar site) scarring (OL-ASCAR-03); this was a double-blind, placebo within-patient controlled, multi-center dose ranging study to evaluate the safety and preliminary efficacy of AZX100 (3.0 mg or 10.0 mg versus placebo) in trocar site scars of subjects who have undergone arthroscopic shoulder surgery. In this trial, AZX100 (or placebo) was administered on Days 9 and 21 following surgery, with no additional dosing throughout the remainder of the trial. One hundred fifty subjects were dosed in the trocar site scarring trial.

Pre-specified endpoints of these studies included evaluations of safety and efficacy of AZX100 based on the subjective primary endpoint Patient and Observer Scar Assessment Scales (POSAS) and objective secondary endpoints analyzed using 2D and 3D high-resolution digital photography.  These endpoints included blinded, independently-scored Visual Analog Scales (VAS) and objective measurements of scar dimensions.
