METHODS FOR REDUCING VIRAL LOAD IN HIV-1-INFECTED PATIENTS

摘要

This invention provides a method of reducing viral load in an HIV-1-infected human subject which comprises administering to the subject an effective HIV-1 viral load reducing dose of a CCR5 receptor antagonist, such as a humanized antibody designated PRO 140 or an anti-CCR5 receptor monoclonal antibody, wherein the viral load reducing dose achieves achieves an average maximum decrease of viral load in the subject of at least 1.83 log10 to 2.5 log10 at about ten days following administration of the CCR5 receptor antagonist and wherein the viral load reducing dose further achieves a mean viral load reduction of 1.7 log10 at about nine days following administration of the CCR5 receptor antagonist. The viral load reducing dose results in a suppression of mean viral load by 1.0 log10 within about four days following administration of the CCR5 receptor antagonist, and suppression of viral load in the subject persists at or below a level of reduction of 1.0 log10 for about two to three weeks. This invention also provides a method of elevating CD4+ cell count in an HIV-1 -infected human subject which comprises administering to the subject at a predefined interval an effective HIV-1 viral load-reducing dose of a humanized antibody designated PRO 140, or an anti-CCR5 receptor monoclonal antibody.
