CD4; HIV gp120

In vitro studies suggest bispecific antibodies targeting CD4 and gp120 could be useful for treating HIV infection. In a viral neutralization assay, bispecific mAbs engineered to recognize both CD4 and gp120 had better potency than the CD4-specific parent mAb ibalizumab. Next steps include preclinical development of the bispecific antibodies as passive immunotherapy for HIV.
In 2007, TaiMed Biologics Inc. licensed ibalizumab from Genentech Inc., now a unit of Roche.
