First liver cancer patient dosed in the MIV-818 phase Ib study

Stockholm, Sweden — Medivir AB (Nasdaq Stockholm: MVIR) today announced that the first patient with advanced liver cancer has been dosed in the phase Ib study of MIV-818. The MIV-818 phase I study (NCT03781934) consists of two parts: (i) the already completed phase Ia, which was a within-patient dose-escalation study, and (ii) the phase Ib between-patient dose-escalation study, a classic 3+3 dose-escalation multi-center study in patients with advanced liver cancer.

The phase Ia study demonstrated a liver-cancer directed effect of MIV-818 and five out of nine patients were considered to have stable liver disease after MIV-818 treatment.

The primary objective of the phase Ib study is to establish the safety and tolerability profile of MIV-818. A secondary objective is to further explore the efficacy of MIV-818.

"Patients with advanced liver cancer have limited treatment options and the unmet medical need is large" said Dr Uli Hacksell, CEO of Medivir. "Having obtained an encouraging proof-of-concept for the liver-cancer directed effect of MIV-818 in phase Ia, we hope to get additional supportive data from the phase Ib study. We believe that MIV-818 has the potential to provide liver cancer patients with major therapeutic benefits."

About liver cancer
Liver cancer is the third leading cause of cancer-related deaths worldwide and hepatocellular carcinoma (HCC) is the most common cancer that arises in the liver. Although existing therapies for advanced HCC are capable of extending the lives of patients, treatment benefits are low while death rates remain high. HCC is a very diverse disease with multiple cancer cell types and without the tumor-specific mutations seen in other tumor types. This has contributed to the lack of success of molecularly targeted agents in HCC. The limited overall benefit, taken together with the poor overall prognosis for patients with intermediate and advanced HCC, results in a large unmet medical need.

About MIV-818
MIV-818 is a pro-drug designed to selectively treat liver cancers and to minimize side effects. It has the potential to become the first liver-targeted, orally administered drug to benefit patients with HCC and other forms of liver cancer.
