May 25, 2011 - Healing spread widens between DSC127 0.03% group and placebo group compared with 12-week data - Wounds up to five times more likely to heal at 24 weeks with DSC127 0.03% versus placebo - Derma Sciences, Inc. (Nasdaq: DSCI), a medical device and pharmaceutical company focused on advanced wound care, announced that in the follow-up portion of its Phase 2 clinical trial in patients with diabetic foot ulcers, the percentage of patients treated with the therapeutic (0.03%) dose of DSC127 with complete healing at 24 weeks following trial enrollment was 73% in the intent-to-treat (ITT) population and 85% in the per-protocol population (PP), a difference of 27 and 33 percentage points, respectively, compared with patients treated with placebo/standard of care (placebo). DSC127 is a patented, topically applied novel angiotensin analog that targets receptors that are up-regulated upon injury to tissue.
Healing was defined as 100% epithelialized with no drainage. The Company previously announced that the 0.03% dose of DSC127 exceeded the trial's goal of an improvement of 15 percentage points in complete healing of wounds at 12 weeks for both the ITT (21 percentage point increase) and PP (27 percentage point increase) populations, compared with placebo. With today's announcement, the improvement at 24 weeks between patients treated with DSC127 0.03% and patients treated with placebo is even more pronounced. There were no drug-related adverse safety events during the entire 24-week study period.
The double-blind, placebo-controlled, multi-center Phase 2 clinical trial randomized 80 patients to receive one of two dose strengths of DSC127 (0.03% or 0.01%) or vehicle placebo control. After 14 days of best standard-of-care to evaluate ulcer healing and ensure the wounds were chronic, those patients randomized into the study received four weeks of active treatment followed by eight weeks of observation and assessment. Although the primary endpoint of the trial was healing at 12 weeks, patients continued to be followed for an additional 12 weeks to gain further information on the drug and its effects. Consistent with what was seen at week 12, the 0.01% dose of DSC127 continued to be comparable to placebo at week 24, and therefore non-therapeutic. The table below shows the percentage of patients healed at weeks 12 and 24, with the 0.03% dose of DSC127 and placebo... Derma Sciences' Press Release -
