EPIX Pharmaceuticals Initiates Phase 1 Multiple Ascending Dose Clinical Trial of PRX-07034 in Obesity.5-HT6 Antagonist Well Tolerated in Single Ascending Dose Phase 1 Trial LEXINGTON, Mass. -- EPIX EPIX Emergency Preparedness Information Exchange EPIX Enhanced Performance unIX EPIX European Property Stock Index Pharmaceuticals, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :EPIX) today announced the initiation of a Phase 1 multiple ascending dose clinical trial to study the safety, tolerability, pharmacokinetics, and pharmacodynamics pharmacodynamics /phar·ma·co·dy·nam·ics/ (-di-nam´iks) the study of the biochemical and physiological effects of drugs and the mechanisms of their actions, including the correlation of their actions and effects with their chemical of PRX-07034 administered once-daily for 28 days in a population of otherwise healthy obese adults with body mass indices between 30 and 42 kg/m2. PRX-07034 is a novel, highly selective 5-HT6 receptor antagonist being developed for the treatment of obesity, as well as for cognitive impairment associated with Alzheimer's Disease Alzheimer's disease (ăls`hī'mərz, ôls–), degenerative disease of nerve cells in the cerebral cortex that leads to atrophy of the brain and senile dementia. and schizophrenia. "We are pleased to announce the initiation of this multiple dose trial of PRX-07034 in obese adults," said Michael G. Kauffman, M.D., Ph.D., chief executive officer of EPIX Pharmaceuticals. "PRX-07034 is the fourth novel drug candidate internally discovered at EPIX. We recently completed a single dose study of PRX-07034 and results from that trial demonstrated that PRX-07034 was well tolerated and supported once-daily oral dosing." Results from the Phase 1 Single Ascending Dose Trial PRX-07034 is a novel, highly selective, small-molecule antagonist of a specific G-protein coupled receptor (GPCR GPCR Guanine Nucleotide-Binding Protein-Coupled Receptor GPCR GTP-binding Protein-Coupled Receptor ) known as 5-HT6. Preliminary safety and tolerability data from a recently completed single ascending dose Phase 1 trial in healthy adult male and female volunteers indicated that single doses of PRX-07034 were well-tolerated up to 2500 mg, the highest dose tested. In addition, PRX-07034 demonstrated adequate absorption, with drug exposures increasing with increasing doses and a half-life of 14 to 24 hours, making it suitable for once-daily dosing. PRX-07034 has also shown cognitive-enhancing properties in preclinical animal models of memory impairment, as well as reductions of both food intake and body weight in several preclinical animal models of obesity. Indications are that the human 5-HT6 receptor is found mainly in the central nervous system with little or no expression in peripheral tissues, which may result in greater drug selectivity with fewer side effects Side effects Effects of a proposed project on other parts of the firm. .
