Preclinical Studies Demonstrate a Viable Intravenous Inosine Formulation
and Support Oral Dosing for Three Alseres' DAT Blocker Compounds
HOPKINTON, Mass., March 10 /PRNewswire-FirstCall/ -- Alseres Pharmaceuticals, Inc. (Nasdaq: ALSE) announced that data from preclinical studies of the Company's nerve repair candidate, Inosine, and DAT Blocker product candidates from its neurodegeneration program were presented at the ASENT conference, March 6-8, 2008 in Arlington, VA.
The first poster presentation entitled: "Brain microdialysate and plasma concentrations of Inosine during intravenous Inosine infusion in conscious rats" highlighted the results of a central nervous system (CNS) microdialysis study designed to measure the levels of Inosine in the brain during intravenous infusion of high concentrations of Inosine. The results suggest that Inosine infused intravenously was measurably able to cross the blood- brain barrier. Inosine is a nerve regenerative factor that has been shown to promote axon outgrowth in neurons and has potential to be used to treat CNS disorders such as stroke, spinal cord injury and traumatic brain injury.
"The literature suggests that Inosine can cross the blood-brain barrier, however, no direct measurements of brain levels of Inosine during systemic dosing have been previously reported," commented Noel Cusack, Ph.D, Alseres' Senior Vice President of Preclinical Development. "This study shows that when administered intravenously using our new, highly-concentrated Inosine formulation, Inosine levels in the brain increased more than 600%, thus offering a viable alternative to more invasive administration."
The second poster presentation entitled: "Brain and Plasma Pharmacokinetics of Three Dopamine Transporter (DAT)-selective Blockers After Administration of a Range of Single Oral Doses in Conscious Mice" summarized the findings of a study to determine brain bioavailability following oral administration of three highly-selective DAT Blockers. The data presented have shown that all three DAT blockers given orally were rapidly absorbed into the blood and the brain and provided favorable brain-to-blood plasma ratios.
"Alseres' DAT blockers have previously been shown to mitigate Parkinson's Disease symptoms in a non-human primate model of PD when given by intramuscular injection. But obviously oral dosing is generally a much more convenient route of routine administration," noted Dr. Cusack. "We believe that this study, using a range of oral doses for three DAT Blockers, has successfully shown that these compounds are potentially attractive candidates for oral treatments of PD."
