Material Changes and Pipeline Updates
- Topical PTH (1-34) for Psoriasis: The FDA accepted a corporate investigational new drug (IND) application in September 2007. The company intends to initiate a Phase 2a multi-center clinical trial involving 54 subjects in the fourth quarter of 2007.
- Altoderm for Atopic Dermatitis: Preliminary data from a European Phase 3 study showed Altoderm was safe and well-tolerated. While treated subjects showed a 33.1% improvement in SCORAD, the study did not achieve statistical significance because the vehicle-only group showed similar improvement. However, a meta-analysis of two studies demonstrated statistically significant improvement in pruritus (itch) versus vehicle. The company is preparing a pre-IND package for the FDA and expects U.S. clinical studies to commence as early as the second quarter of 2008.
- Hedrin for Head Lice: Currently marketed in Western Europe with sales exceeding $40 million and market share of at least 40% in certain countries. The company is pursuing a Premarket Approval (PMA) pathway as a medical device and plans to meet with the FDA in the first quarter of 2008.
- Altolyn for Mastocytosis: The company is developing a GMP-compliant manufacturing process. It is evaluating an accelerated 505(b)2 regulatory pathway or orphan drug designation and exploring additional indications for food allergy and gastrointestinal disorders.
Guidance, Outlook, and Risks
Management anticipates initiating clinical activities for Hedrin in 2008 and U.S. studies for Altoderm in the second quarter of 2008. The filing includes a Safe Harbor statement identifying significant risks, including the lack of significant revenues, the need for additional financing, the uncertainty of clinical trial results, and the ability to obtain regulatory approvals. The company also notes the illiquidity and volatility of its common stock.
