Karolinska Development’s portfolio company Umecrine Cognition publishes clinical research results in a highly regarded journal

STOCKHOLM, SWEDEN – Karolinska Development AB (Nasdaq Stockholm: KDEV) announces today that its portfolio company Umecrine Cognition has published results from the recently conducted phase 2a study of the drug candidate golexanolone in the highly regarded scientific journal Journal of Hepatology. The study results show that the company’s drug candidate has a positive effect on neuropsychiatric outcome measures, is well tolerated and has a favorable pharmacokinetic profile even at high and repeated doses. The results strengthen the potential for golexanolone as part of future treatments for hepatic encephalopathy.

Liver failure may over-activate the GABA system in the brain, causing cognitive disturbances and sleep disturbances that reduce the quality of life for both patients and their close relatives. Umecrine Cognition is developing golexanolone (formerly GR3207), a drug candidate with a novel mechanism of action aimed at the GABAA receptor in the brain. The drug candidate acts by attenuating the incorrect activation of the receptor and can thus restore normal nerve signaling.

The scientific article presents results from a recent phase 2a clinical trial with single and increasing doses (SAD) as well as repeated and increasing doses (MAD) of golexanolone in 77 liver cirrhosis patients. The study evaluated the safety profile and pharmacokinetics of the drug candidate. The results show that golexanolone has a good safety profile and favorable pharmacokinetics, including good systemic distribution.

In an exploratory sub-study, the efficacy of the drug candidate was evaluated in 45 patients with cognitive impairment due to early hepatic encephalopathy, also known as covert hepatic encephalopathy (CHE), receiving either active treatment with golexanolone or placebo. Following the treatment period, the effect of golexanolone on CHE and the risk of disease progression from CHE to overt liver encephalopathy (HE) were analyzed. In summary, the study results indicate that golexanolone has a positive effect on cognition through improved responsiveness (CRT), normalized brain signaling (EEG) and improved sleep status (ESS). The positive phase 2 results support continued development investments in the drug candidate.

“We are delighted that Umecrine Cognition’s successes are being spread in international scientific media. It is an important recognition of the high quality of the company’s development efforts of drugs against hepatic encephalopathy – a complicated disease state where the need for effective treatment is pronounced,” comments Karolinska Development’s CEO, Viktor Drvota.

Karolinska Development’s ownership interest in Umecrine Cognition amounts to 72%.
