NEW YORK, July 10 (HSMN NewsFeed) -- Manhattan Pharmaceuticals, Inc. (Amex: MHA ) today provided an update regarding the company's pipeline. As announced yesterday, the company intends to continue with the advancement of its four clinical stage product candidates, and the exploration of other opportunities in the areas of dermatology/immunology and endocrine/metabolic disorders. The four product candidates include topical PTH (1-34) for psoriasis, as well as Altoderm(TM) for atopic dermatitis (eczema), Altolyn(TM) for mastocytosis, and Hedrin(TM) for head lice.

Topical PTH (1-34) -- Manhattan Pharmaceuticals is developing topical PTH (1-34) for the treatment of psoriasis. Approximately 4.5 million Americans suffer from psoriasis creating a potential U.S. market of approximately $400 million for topical therapies. The company is currently conducting preclinical studies on its improved topical formulation for PTH (1-34) and intends to submit a corporate investigational new drug application (IND) in the third quarter of 2007. Pending the outcome of that IND submission, the company intends to initiate a randomized, double-blind, placebo-controlled Phase 2a clinical trial in 2H07. In addition, the company has filed new patent applications in the U.S. with respect to the product.

Altoderm(TM)-- In April 2007, Manhattan Pharmaceuticals acquired the North American rights to develop and commercialize Altoderm for the treatment of atopic dermatitis, or "eczema." Eczema represents a major potential market opportunity. According to the National Institutes of Health, 15 million Americans suffering from the condition, and insurance companies spending more than $1 billion annually for treatment. Altoderm is presently being studied in an ongoing Phase 3 clinical trial being conducted in Europe by Thornton & Ross Limited. Preliminary data from this European study are expected in 3Q07. Altoderm previously completed a randomized, double-blind, placebo-controlled, parallel-group, Phase 3 clinical study in the United Kingdom (UK). The results of that study were published in the British Journal of Dermatology in February 2005. These studies have been conducted according to UK regulatory requirements and are expected to be submitted to the UK authorities in pursuit of marketing authorization. Manhattan Pharmaceuticals is presently preparing to meet with the United States Food and Drug Administration (FDA) to determine the regulatory pathway for Altoderm in the U.S. The company expects this meeting to take place in 2H07.

Altolyn(TM)-- In April 2007, Manhattan Pharmaceuticals acquired the North American rights to develop and commercialize Altolyn for the treatment of mastocytosis. The company believes that Altolyn may be a candidate for an accelerated 505(b)2 regulatory pathway or orphan drug designation in this indication. Early UK clinical experience also suggests that Altolyn may have potential for patients with food allergy and gastrointestinal functional disorders. The company is presently preparing to meet with the FDA to discuss these possibilities and any additional regulatory considerations for Altolyn in the U.S. The company expects this meeting to take place in 2H07.

Hedrin(TM)-- In June 2007, Manhattan Pharmaceuticals acquired the North American rights to develop and commercialize Hedrin, a non-insecticide product candidate for the treatment of head lice. According to the American Academy of Pediatrics, an estimated 6 to 12 million Americans are infested with head lice each year. Hedrin is currently marketed in Europe and in the UK, and according to market research firm Information Resources, Inc., has recently achieved significant market share (greater than or equal to 40%) in certain European countries. Manhattan Pharmaceuticals is presently preparing to meet with the FDA to determine the regulatory pathway for Hedrin in the U.S. The company expects this meeting to take place in 2H07.

In addition to these programs, Manhattan Pharmaceuticals will continue to explore other opportunities in the areas of endocrine and metabolic disorders.

On July 9, 2007, Manhattan Pharmaceuticals announced the company has discontinued development of oral Oleoyl-estrone for the treatment of common obesity and morbid obesity due to the compound's failure to demonstrate statistical and clinically meaningful weight loss in recently completed Phase 2a clinical trials. The company also reported that it intends to pursue appropriate outlicensing opportunities for Propofol Lingual Spray for pre-procedural sedation.
