DURHAM, N.C.--(BUSINESS WIRE)--Argos Therapeutics today announced the presentation of data from the Phase 2a trial of AGS-004, providing information on rebound viral genetic diversity in HIV patients treated with the personalized immunotherapy following antiretroviral therapy (ART) interruption. The data were discussed in a poster session at the Keystone Symposia Global Health Series HIV Vaccines meeting, held March 21-26, 2010 in Banff, Canada. AGS-004 is a product of the Company’s Arcelis™ technology, and it is a personalized, RNA-loaded, dendritic cell-based immunotherapy that is perfectly matched to each patient’s unique HIV viral burden. Argos recently reported interim data from the Phase 2a trial, demonstrating viral load control in the absence of antiretroviral therapy and robust immune responses to a diverse set of HIV antigens. Argos plans to initiate a Phase 2b trial in the first half of 2010.
