DP-b99 Phase IIb Trial Results to be Presented at the European Stroke Conference

Tuesday May 29, 3:01 am ET

REHOVOT, Israel, May 29 /PRNewswire/ -- D-Pharm announced today that the results of the Phase IIb trial for its neuroprotective compound DP-b99 in the treatment of acute ischemic stroke patients will be presented at the European Stroke Conference. The data will be presented by the study's German principal investigator Prof. H. C. Diener, on Thursday May 31st at 14.30 in the Carron Room, at the Scottish Exhibition Conference Center in Glasgow. The abstract for the presentation may be viewed using the European Stroke Conference search engine at: http://www.eurostroke.eu/gla_searching.htm .

DP-b99, discovered and developed by D-Pharm, is a unique neuroprotective drug that addresses an array of damaging processes occurring in the brains of stroke patients. A Phase IIb multicenter, double blind, placebo controlled, randomized trial to assess DP-b99's effect on stroke outcomes was completed in December 2006. The study enrolled 150 ischemic stroke patients with signs of cortical involvement and NIH Stroke Scale (NIHSS) score of 7-20. DP-b99 (1mg/kg/day) or placebo was administered i.v. within 1-9 hours of stroke-onset as a 4-day course of once-daily 2hr infusions with a 90-day follow-up.

The main pre-defined efficacy endpoints in the study included: the change in National Institute of Health Stroke Scale (NIHSS) score from day 0 to day 90; the percent of patients completely recovered after stroke (score 0 or 1, or same as pre-stroke) at day 90 as assessed by the modified Rankin scale or NIHSS.

The day 90 recovery rate in the DP-b99 treated group was two times higher than in the placebo group. Specifically, the recovery rate in the DP-b99 and placebo groups per modified Rankin scale was 30.6% and 16.0% (p=0.05), per NIHSS was 23.6% and 12.0% (p=0.08), and defined by either scale was 37.5% and 18.7% (p=0.02), respectively. The day 90 median change from baseline was 6.0 and 5.0 NIHSS points in the DP-b99 and placebo groups, respectively; the day 90 median change from baseline in patients with entry NIHSS score of 10-16 was 8.0 and 5.0 points in the DP-b99 and placebo groups, respectively (p=0.03).

The trial enrolled patients within the first 9 hours following appearance of stroke symptoms. The data indicate that the effect of DP-b99 on recovery was uniform across the full 9h window, confirming the wide therapeutic window for DP-b99.

The favorable safety and tolerability profile of DP-b99 was confirmed and is in line with D-Pharm's previous clinical experience from the Phase I and IIa studies. There were no significant differences in the number or type of serious adverse events, mortality rate or death causes between the DP-b99 and placebo groups.

These results show that DP-b99 doubled the chances to recover from ischemic stroke, has at least a 9hr therapeutic window and is safe. D-Pharm is planning to commence a pivotal Phase III study of DP-b99 in 2008.
