Karolinska Development’s portfolio company Dilafor reports maintained effect in the extension study of tafoxiparin

STOCKHOLM, SWEDEN – February 14, 2023. Karolinska Development AB (Nasdaq Stockholm: KDEV) today announces that its portfolio company Dilafor’s extended clinical phase 2b study with the drug candidate tafoxiparin has resulted in further positive data. The extension of the study met its objective, which was to evaluate if the efficacy of tafoxiparin obtained in the phase 2b trial persists when the drug is administered in additional doses.

In a clinical phase 2b study, tafoxiparin showed a significant positive effect on cervical ripening in first-time mothers that were given treatment for a planned start of labor. The completed extension of the phase 2b study included a total of 164 women, and the results show that the cervical ripening effect persists in the study. In addition, a clear dose-response relationship was observed.

Up to 30 percent of all pregnant women are subject to planned start of labor, the current interventions increase the risk of medical complications in both mother and child, leading to high healthcare costs.

"The consistency of the study results reinforces the hypothesis that tafoxiparin has great potential to reduce the risks for both mother and child at planned start of labor. Tafoxiparin’s ability to maintain the effect in the study is a sign of strength ahead of the drug candidate’s continued development,” says Viktor Drvota, CEO, Karolinska Development.

Karolinska Development's direct ownership in Dilafor amounts to 1% and indirect ownership interest via KDev Investment in Dilafor amounts to 30%.
