Kuros reported positive interim results from a phase IIa trial of KUR-212 for the treatment of severe burns. This randomized, open-label, active-control, single-group assignment study enrolled 10 subjects with severe burns requiring autologous meshed skin grafting. The subjects served as their own control, with an area of graft that was stapled and an area of graft that was treated with KUR-212. The trial was designed to assess the safety and efficacy of KUR-212 on wound closure (full re-epithelialization) over two separately reported periods of one and 12 months respectively. The primary endpoint was incidence of treatment-related adverse events up to 28 days post surgery. In the one-month follow-up there were no treatment-related adverse events. A difference was observed in the time to wound closure between treatments, with a shorter time for the KUR-212-treated group. However, the small sample size did not allow for statistical evaluation of efficacy. The 12 month data is expected in Q2 2009.

ZymoGenetics reported positive data from a clinical trial of Recothrom in subjects undergoing skin grafting for burns. This multiple site, single-arm, open-label study enrolled 72 subjects receiving partial- or full-thickness autologous sheet or mesh graft following burn injury. Recothrom was applied to newly excised wounds (graft recipient sites) using a ZymoGenetics pump spray device. Adverse events, skin graft survival and formation of anti-Recothrom antibodies were measured at baseline and Day 29 after application of Recothrom. Treatment was generally well tolerated; adverse events occurred in 63 (88%) of the subjects and were typical of adverse events seen following acute burn wound treatment. One subject had antibodies to Recothrom at baseline (1.4%); another subject developed specific antibodies to Recothrom at Day 29 resulting in a low rate of antibody formation (1.6%). The antibodies detected did not neutralize human thrombin.

BioMarin reported positive results of their phase I b study of Vibrilase (vibriolysin), their topical enzymatic treatment for serious burns. Data indicated that the drug was safe and well tolerated at all trial doses, and demonstrated preliminary efficacy in debriding burn tissues and improving the time to 90% epithelialization (the point at which wounds appear to be healing normally); cohort size was deemed insufficient to establish a dose response relationship. The trial found the drug to be safe and well tolerated, with non-dose related transient application pain observed most frequently. The trial collected safety data from a total of 19 subjects, and efficacy data from 12 subjects, all of whom were conscious and had partial-thickness burns over 1-2% of their body. Subjects received one of three topical doses of Vibrilase daily for three days, followed by a 28 day observation period.
