Alamifovir is a novel antiviral agent which was under development with Mitsubishi Pharma Corporation in Japan as a potential treatment for hepatitis B (HBV). Alamifovir and its hydrolyzed derivatives have shown preclinical efficacy activity against wild-type and lamivudine-resistant hepatitis B virus. The effective concentration of alamifovir required to reduce replication by 50% (EC50) for the wild-type was 0.027 uM, which is approximately 20 times less than lamivudine, and the EC50 for the lamivudine-resistant mutants was 2.6 to 3.3 uM. The mechanism of action of alamifovir appears to be via the inhibition of the protein priming reaction and the packaging reaction, thereby decreasing HBV replication. Alamifovir`s development has been discontinued.

Two studies were conducted to examine the single- and multiple-dose alamifovir pharmacokinetics after oral administration in healthy males. In study 1, subjects were given single doses (0.2 to 80 mg), with a subset receiving 20 mg in a fed state. Study 2 subjects were dosed with 2.5 to 15 mg twice daily for 15 days.
