MacroChem Corporation (OTCBB: MACM - News) has announced that it has signed an exclusive option to acquire exclusive worldwide license rights for drug uses of pexiganan, a novel, small peptide anti-infective for topical treatment of patients with mild diabetic foot infection (DFI), from Genaera Corporation (Genaera).

"We believe this is a unique opportunity for MacroChem to broaden its product portfolio with a product that has already completed two Phase 3 clinical trials. It also fits our strategic focus and complements our lead product candidate, EcoNail(TM) for treatment of nail fungus currently in a fully enrolled Phase 2 trial and progressing on track with an interim assessment of clinical data later this year after all patients have been treated for twenty four weeks," said Robert J. DeLuccia, President and CEO of MacroChem.

Clinical trials with pexiganan previously conducted by Genaera include two Phase 3 trials submitted in a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in 1998. At that time, outstanding issues with CMC (Chemistry, Manufacturing and Controls) and an FDA request for one additional controlled trial precluded approval.

Mr. DeLuccia further noted, "We would be pleased to have pexiganan in our hands since we believe that, if approved, it would be welcomed by physicians and patients for the treatment of diabetic foot infection. In recent years, there have been many advances in the manufacturing of peptides, a better understanding of the treatment of diabetic foot infection, improvements in clinical trial design and execution, and more clarity concerning regulatory requirements for topical anti-infectives with the potential market being even more attractive than before."

He added, "There continues to be a very large and growing incidence of diabetes and, as a result, a growing number of diabetic foot infections in the U.S. Diabetic foot ulcers in the approximately 20 million diabetics in the US alone are a major concern and burden to both patients and healthcare system. There is also a lack of effective topical anti-infectives to treat diabetic foot infection. Accordingly, we believe that pexiganan could fill an important unmet medical need for a topical anti-infective treatment and provide a significant commercial opportunity in an addressable market of approximately 3.5 million diabetic foot infections annually."

The option agreement gives MacroChem a 90-day exclusive right to enter into a license agreement with Genaera. MacroChem paid Genaera $250,000 on execution of the option agreement.

Both EcoNail and pexiganan would be developed to treat diseases of the foot predominantly treated by the same prescribing specialists, namely podiatrists. Both products would potentially be of interest to a larger number of physician specialists and primary care physicians as well. EcoNail is the company's patented lacquer which contains the antifungal econazole and MacroChem's enhancer SEPA®. Patients participating in the EcoNail study will receive 48 weeks of treatment and will undergo efficacy assessments using standard criteria of nail appearance and mycology. However, the Company will collect and evaluate 24-week interim data later this year. This trial was specifically designed, with the assistance of well-known onychomycosis experts, to address three important objectives: to assess early signs of efficacy, to maintain robust clinical endpoints in the full study, and, if successful, to facilitate advancement to Phase 3 as soon as possible.
