Via press release:
Sangamo BioSciences, Inc. (Nasdaq: SGMO) announced today the initiation of two new Phase 2 clinical studies (SB-728-1101 and SB-728-902, Cohort 5) in its program to develop a "functional cure" for HIV/AIDS. Sangamo's ZFP Therapeutic® approach (SB-728-T) generates T-cells that are resistant to HIV infection using its zinc finger nuclease (ZFN) technology to permanently disrupt the DNA sequence encoding CCR5, a co-receptor used by HIV to enter cells. The company expects to present data from its SB-728-T HIV clinical trials at appropriate medical meetings in 2012.Most interesting: "In addition to safety, the study will evaluate the effect of escalating doses of Cytoxan on SB-728-T engraftment, the effect of SB-728-T treatment on viral load following HAART interruption." In other words (I think), they'll be looking at whether patients can cease taking meds after the treatment.
