Alkermes Presents Positive Preclinical Data on Novel, Proprietary Molecule Designed to Improve Outcomes for Patients Taking Opioid Analgesics
Second New Program Disclosed During Calendar 2008
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alkermes, Inc. (NASDAQ: ALKS) today announced positive preclinical results for its proprietary small molecule candidate, RDC-1036, which emerged from a library of novel opioid modulators. The data demonstrated RDC-1036 was effective in reversing opioid effects on gastrointestinal motility. Data also showed that oral administration of RDC-1036 had greater efficacy at a lower dose and for an extended period of time compared to an active comparator, methylnaltrexone. The data were presented at the 38th Annual Meeting of the Society for Neuroscience in Washington, D.C.
According to IMS Health, 200 million prescriptions were written for opioids in 2007 in the United States. Many studies indicate that a high percentage of patients receiving opioids are likely to experience side effects affecting gastrointestinal motility.
"While opioids are a common and effective treatment for managing chronic pain, the side effects of these medications can be debilitating and may diminish patient adherence to pain medication," stated Daniel Deaver, Ph.D., vice president, non-clinical development of Alkermes. "We are encouraged by these preclinical results as they suggest that the unique, oral formulation of RDC-1036 may enable the use of pain medications without inhibiting gastrointestinal motility."
The study results presented included efficacy and sustainability data of RDC-1036 compared to methylnaltrexone administered orally and parentally in a well-characterized rodent model of gut motility. Data showed that treatment with oral RDC-1036 blocked opioid-induced side effects for up to four hours at a dose three-fold lower than oral methylnaltrexone. Additionally, oral RDC-1036 had a faster onset of action compared to methylnaltrexone and maintained sustained efficacy for at least eight hours, compared to four hours with methylnatrexone. These data suggest oral RDC-1036 may be effective in reducing gastrointestinal side effects associated with opioid use.
"We are pleased to present these data on RDC-1036 as an example of our emerging proprietary pipeline," said Elliot Ehrich, M.D., chief medical officer of Alkermes. "These preclinical results are encouraging and suggest that we can successfully leverage our biological and chemical expertise to advance candidates from discovery to development."
