STOCKHOLM - April 21, 2017. Karolinska Development's (Nasdaq Stockholm: KDEV) portfolio company Umecrine Cognition AB, whose novel orally-active GABAA receptor modulating steroid, GR3027, is in clinical development for hepatic encephalopathy (HE), will present clinical results from its Phase 1 study at The International Liver CongressTM 2017, the annual meeting of the European Association for the Study of the Liver, being held April 19-23, 2017, in Amsterdam, The Netherlands.
The poster, entitled "GR3027 reverses neurosteroid-induced GABAA receptor-mediated inhibition of brain function: A human challenge study", presents results of the human challenge part of the Phase 1a study designed to evaluate single-dose safety, tolerability and CNS target engagement of GR3027 in healthy adults. The challenge component involved a three-part cross-over design, in which healthy male subjects were randomized to receive placebo or two different doses of GR3027 prior to challenge. Its principle objective was to evaluate the ability of GR3027 to antagonize allopregnanolone-induced activation of GABAA as determined by its pharmacodynamic effects on two GABAA-modulated CNS functions, Saccadic Eye Velocity (SEV) and self-rated sedation using a Visual Analogue Scale (VAS).
Key findings presented in the poster include the following:
Enhanced GABAergic tone via neurosteroid-induced allosteric activation of GABAA receptors is emerging as critical to the pathogenesis of HE, prompting efforts to develop agents that antagonize GABAA receptor-potentiating neurosteroids . GR3027, a novel orally active small molecule designed to reduce GABAA receptor mediated inhibition of brain function by antagonizing endogenous inhibitory neurosteroids such as allopregnanolone, has been shown to be effective in animal models of HE , and the present findings demonstrate its ability to modulate the function of CNS GABAA receptors in humans. A Phase 1b/2a clinical study designed to assess safety, tolerability and PK of multiple ascending doses in healthy adults and patients with cirrhosis as well as preliminary exploration of the effect of GR3027 on cognitive function in cirrhotics is underway.
The poster will be presented on Friday, April 21, 2017, in Hall 1 session Cirrhosis and its complications: Clinical aspects, RAI Amsterdam Convention Center.
