November 22, 2010

Diffusion Pharmaceuticals issued positive results from a phase I/II trial of Trans Sodium Crocetinate (TSC) for the treatment of walking impairment due to peripheral artery disease (PAD). This randomized, double-blinded, placebo-controlled study enrolled 48 subjects with intermittent claudication symptoms from PAD. The subjects received TSC at doses of 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75 and 2.0 mg/kg or placebo. Study medication was dosed intravenously as a bolus injection once daily for five consecutive days. Data showed a notable dose response for peak walking time on a graded treadmill test at several TSC dosing levels after five days of treatment. There was a clinically meaningful improvement for the subjects who received 1.50 mg/kg of TSC of nearly three times the improvement observed with the placebo group. TSC was safe and well-tolerated at all doses.

Of the subjects, 27 received AMG 0001 8mg (4mg x 2) and 13 received placebo.The primary endpoints, improvement of rest pain ((VAS (Visual Analog Scale)) orischemic ulcer size, at 12 weeks post dosing, showed statistical significance,with a 70.4% improvement in the AMG0001 group versus a 30.8% improvement in theplacebo group (p=0.014). Treatment was well tolerated, with adverse reactionssimilar between the groups.
