IRLAB’s clinical drug candidate mesdopetam published in JPET
IRLAB announced today that a scientific paper reporting the preclinical pharmacology of mesdopetam (IRL790), a dopamine D3 receptor antagonist for the treatment of motor and psychiatric complications in Parkinson’s disease, is now published in the Journal of Pharmacology and Experimental Therapeutics, JPET. An additional paper is also published in JPET, indicating that mesdopetam could have beneficial effects on neurotrophic factors important for preserved synaptic function and nerve cell signaling.
"The two papers now published in JPET add to the growing body of data supporting mesdopetam as a very promising drug candidate for the treatment of both motor and psychiatric complications in Parkinson’s disease. Furthermore, the study adds to the increasing number of scientific publications indicating a significant role for the dopamine D3 receptor as a drug target in Parkinsons disease", says Susanna Waters, M.D., Ph.D, Director of Biology & Biostatistics at IRLAB.
JPET, The Journal of Pharmacology and Experimental Therapeutics, is a highly ranked international research journal in the field of pharmacology. The journal is published by The American Society for Pharmacology and Experimental Therapeutics.
Mesdopetam is a drug candidate in clinical Phase II and is being developed by IRLAB Therapeutics for the treatment of levodopa induced dyskinesia in Parkinson's disease (PD-LIDs) and Parkinson's disease psychosis (PD-P).
The publication that reports on preclinical pharmacology demonstrates that mesdopetam is active in models of levodopa-induced dyskinesias (LIDs) and in models of psychosis. This effect profile is attributed to antagonism at Dopamine D3 receptors, supported by in vitro studies and molecular modelling results.
The publication by scientists affiliated at The Centre for Molecular Medicine (CMM), Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden, reports on the effects of mesdopetam on protein levels and phosphorylation states of proteins and concludes that mesdopetam could have positive effects on nerve cell proteins important for synaptic plasticity and nerve cell signaling.
The two papers were published online as part of JPET Fast Forward, which contains papers in manuscript form that have been accepted and published in JPET but have not been copyedited and have not been assigned to an issue of the journal. Copyediting, including graphics, may lead to some differences between the Fast Forward version and the final version.
