NOVATO, Calif., June 1 /PRNewswire-FirstCall/ -- Raptor Pharmaceuticals Corp. ("Raptor" or the "Company") (OTC Bulletin Board: RPTP), today announced that it has dosed the first patient in its Phase 2b clinical trial, conducted in collaboration with the
The Phase 2b clinical trial will enroll up to six cystinosis patients with a history of good compliance using the currently available immediate-release form of cysteamine bitartrate, the only drug cleared for marketing by the U.S. Food and Drug Administration ("FDA") and European Medicines Agency ("EMEA") to treat cystinosis. The clinical trial will evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of a single dose of DR Cysteamine in patients. Data from the study are expected in the third quarter of 2009. Raptor plans to follow the Phase 2b clinical study with a pivotal, Phase 3 clinical study in cystinosis patients anticipated to commence in the fourth quarter of 2009.
DR Cysteamine is Raptor's proprietary enteric-coated micro-bead formulation of cysteamine bitartrate contained in a gelatin capsule and designed for increased absorption, less frequent dosing and improved tolerability relative to the current standard of care. Published studies have shown that fewer than 25% of patients taking immediate-release cysteamine bitartrate are fully-compliant due to the drug's strict every-six hour dosing schedule and dose-limiting side effects, including gastrointestinal ("GI") problems such as stomach aches, nausea and vomiting.
Patrice Rioux, M.D., Ph.D., Raptor's Chief Medical Officer stated, "We are pleased that enrollment is now underway in our Phase 2b clinical trial in cystinosis. This is an underserved patient population and there is a compelling need for an improved treatment option. Many patients are unable to take adequate levels of the drug to halt the progression of their disease, which gradually destroys the organs in the body. We believe DR Cysteamine could have positive effects on the long-term health of cystinosis patients as well as the quality of life for patients, their families and caregivers."
Bruce Barshop, M.D., Ph.D., Professor of Clinical Pediatrics at UCSD and principal investigator for the cystinosis clinical trial, commented, "The initiation of this cystinosis trial offers us an opportunity to evaluate the potential for an improved treatment invented here at UCSD and further developed by Raptor. We're pleased to collaborate with Raptor in this effort to advance the standard of care in cystinosis."
