Mouse studies suggest a combination of neutralizing antibodies could help treat HIV. In a humanized mouse model of HIV, individual antibodies with high in vitro potency against various HIV epitopes decreased viral RNA compared with no treatment but led to viremia rebound after 14-16 days. In the mouse model, a combination of five such antibodies against different binding sites, including CD4 and different HIV epitopes, suppressed HIV viral load for up to 60 days after discontinuing therapy, whereas antiretroviral therapies suppressed viral load for 10 days after discontinuing therapy. Next steps include clinical trials.
