"Our Phase 1 trials continue to provide valuable insight into the durability and unprecedented effects of SB-728-T treatment on immune system health in HIV-infected individuals," said Geoff Nichol, M.B., Ch.B ., Sangamo's executive vice president of research and development. "In addition we are making good progress in two Phase 2 clinical trials designed to maximize the engraftment of SB-728-T. We expect to present preliminary data in the first half of 2013 and a full data set in the second half of next year. The ground-breaking clinical data that we and our collaborators are generating continues to validate this treatment as a promising approach to provide a 'functional cure' for HIV/AIDS."ICAAC Presentations Abst.#H533: "Preferential expansion of transitional (T TM) and Central Memory(T CM) CD4 T-cells following adoptive transfer of ZFN CCR5 Modified Autologous CD4 T-cells."

Tuesday, September 11, 2012, Poster Session 180 (H) HIV-I Resistance, Tropism and Novel Laboratory Methods The presentation will describe a new highly sensitive method developed by Sangamo scientists that enables accurate quantification of very low copy numbers of HIV DNA genomes, which may be a useful tool for evaluating interventions targeting the HIV reservoir, particularly Sangamo's approach to a 'functional cure' for the disease. For a more complete description of the technique click here About SB-728-T Sangamo's drug, SB-728-T, is generated by ZFN-mediated modification of the gene encoding the CCR5 receptor in a patient's own T-cells. ZFN modification disrupts the expression of this key co-receptor for HIV entry and renders cells resistant to HIV infection. The approach is based on the observation that a naturally occurring mutation in the CCR5 gene, CCR5 delta-32, provides protection from HIV infection. Individuals in whom both copies of the CCR5 gene carry the delta-32 mutation are generally not susceptible to the most common strain of HIV.
