Medivir AB announced that clinical pharmacokinetic (PK) data on dose linearity and systemic exposure from the first study with fostroxacitabine bralpamide (fostrox) (NCT03781934) will be presented at the European Association for the Study of the Liver (EASL) Liver Cancer Summit on February 23, 2024, in Rotterdam. The abstract, titled "Population pharmacokinetic modeling of orally administered fostroxacitabine bralpamide (fostrox, MIV-818) and its metabolite troxacitabine in a phase I/IIa liver cancer study" will be presented at the conference by Karin Tunblad PhD, Project Director for fostrox at Medivir. The presentation includes pharmacokinetic results from 42 patients in the phase I/IIa clinical study with fostrox monotherapy and the fostrox + Lenvima® combination in advanced liver cancer.

The results show dose linearity and that the systemic exposure, at the recommended phase 2 dose for fostrox, aligns with the encouraging safety and tolerability profile experienced in the ongoing phase 1b/2a study with fostrox in combination with Lenvima in second line treatment of advanced hepatocellular carcinoma (HCC). In addition, the study shows that the exposure of fostrox is not impacted by administration of Lenvima, providing additional support for this combination. The abstract and the poster will be available on Medivir's website after the presentation.
