    • 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 log 10 to 2.5 log 10 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 log 10 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 log 10 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 log 10 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.
    • 本发明提供了一种降低HIV-1感染的人受试者中的病毒载量的方法,其包括向受试者施用有效的HIV-1病毒载量减少剂量的CCR5受体拮抗剂,例如命名为PRO 140的人源化抗体或抗 - -CCR5受体单克隆抗体,其中所述病毒负荷降低剂量达到达到在约1小时至少1.83log 10至2.5log 10/10的受试者中病毒载量的平均最大降低 在施用CCR5受体拮抗剂后十天,并且其中病毒载量降低剂量在施用CCR5受体拮抗剂后约9天进一步达到1.7log 10的平均病毒载量降低。 在施用CCR5受体拮抗剂后约4天内,病毒载量降低剂量导致平均病毒载量的抑制为1.0log 10,并且受试者的病毒载量的抑制持续在或低于一个水平 减少1.0log 10,持续约2-3周。 本发明还提供了一种在HIV-1感染的人受试者中提高CD4 +细胞计数的方法,其包括以预定间隔向所述受试者施用命名为PRO 140的人源化抗体的有效的HIV-1病毒载量降低剂量,或 抗CCR5受体单克隆抗体。
