    • The present invention provides compositions and methods of treating hepatitis virus infection, particularly hepatitis C virus infection. The invention provides methods of treating a hepatitis virus infection, involving administering a first form and a second form of IFN-α to provide a multiphasic pharmacokinetic profile. The multiphasic antiviral agent serum concentration profile that is achieved effects an initial rapid drop in viral titer, followed by a further decrease in viral titer over time, to achieve a sustained viral response. The invention further provides compositions that are effective in achieving a multiphasic IFN-α profile. Compositions of the invention comprise at least a first form of interferon-α (IFN-α) that has a first pharmacokinetic profile and a second form of IFN-α that has a second pharmacokinetic profile, where the second form of IFN-α has a longer mean residence time than that of the first form of IFN-α. The invention further provides compositions comprising C-terminally modified IFN-α.
    • 本发明提供治疗肝炎病毒感染,特别是丙型肝炎病毒感染的组合物和方法。 本发明提供治疗肝炎病毒感染的方法,包括施用第一种形式和第二种形式的IFN-α以提供多相药代动力学特征。 实现的多相抗病毒剂血清浓度分布影响病毒滴度的初始快速下降,随后随着时间的推移进一步降低病毒滴度,以实现持续的病毒反应。 本发明还提供了有效实现多相IFN-α谱的组合物。 本发明的组合物包含具有第一药代动力学特征的第一形式的干扰素-α(IFN-α)和具有第二药代动力学特征的第二形式的IFN-α,其中第二形式的IFN-α具有 比第一种形式的IFN-α的平均停留时间更长。 本发明还提供包含C-末端修饰的IFN-α的组合物。
