Karolinska Development’s portfolio company Umecrine Cognition presents positive safety data from the first part of its Phase 1b/2 study in PBC


STOCKHOLM, SWEDEN – March 22, 2024. Karolinska Development AB (Nasdaq Stockholm: KDEV) today announces that its portfolio company Umecrine Cognition has presented a positive safety data from the first part of its clinical Phase 1b/2 study of golexanolone in patients with Primary Biliary Cholangitis, PBC. The second part of the study, which will now be initiated, aims to evaluate the preliminary efficacy of the drug candidate and further study its safety and tolerability profile. Top-line results are expected in H1, 2025.

Umecrine Cognition is developing a new class of drugs to treat cognitive symptoms caused by liver disease. The company’s lead drug candidate, golexanolone, is currently being evaluated in a randomized, double-blind, placebo-controlled, clinical Phase 1b/2 study in patients with primary biliary cholangitis (PBC) who experience clinically significant fatigue and cognitive symptoms. The first part of the study aimed to evaluate golexanolone’s safety and tolerability profile, as well as the pharmacokinetic profile, and the data generated provided important guidance on the dosing intervals in the second part of the study.

The study’s internal safety review committee (iSRC) has authorized the initiation of the second part of the study without dose adjustments and the first patient is expected to be included during the second quarter. Approximately 84 subjects will be randomized to the second part of the study which aims to investigate preliminary treatment efficacy signals. The evaluation also includes a planned interim analysis when a third of the patients have been included. Top-line results are expected in H1, 2025.


“In previous clinical and preclinical studies, Umecrine Cognition’s drug candidate golexanolone has shown strong potential to counteract an incorrect suppression of brain activity, causing extreme fatigue and difficulty with concentration. We are happy that the current study is progressing and look forward to the results from the second part,” says Viktor Drvota, CEO of Karolinska Development.

Karolinska Development’s ownership in Umecrine Cognition amounts to 73 percent.
