ICAAC 2014: New Tenofovir Alafenamide Combo Pill Has Less Effect on Kidneys and Bones

An experimental single-tablet regimen containing a new version of tenofovir (tenofovir alafenamide or TAF) and the HIV protease inhibitor darunavir (Prezista) worked as well as a similar regimen containing the older tenofovir disoproxil fumarate (TDF) formulation,but it had less detrimental effects on kidney function and bone density, according to a study presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy this week in Washington, DC.

ICAAC 2014: Sangamo Provides Update on Gene Therapy to Protect T-cells From HIV

Several people with HIV whose CD4 T-cells were modified to make them resistant to viral entry have maintain low-level viral load after interrupting antiretroviral therapy (ART), with 1 individual having HIV RNA <1000 copies/mL for more than a year, according to a presentation at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy this week in Washington, DC.

AIDS 2014: Low Level Viral Load Does Not Raise Risk of HIV Treatment Failure

People with HIV who have a low-level viral load between 20 and 50 copies/mL were not more likely to experience virological failure of antiretroviral therapy (ART) compared with those who consistently maintained viral suppression below 20 copies/mL, according to research presented at the 20th International AIDS Conference in Melbourne.

Maraviroc Dose May Be Too Low for Many African-American People with HIV

A standard dose of the CCR5 antagonist maraviroc (Selzentry) may not be effective for many black people with HIV due to a genetic variation which increases production of a cytochrome P450 protein that speeds up processing of the drug, according to a study published in the August 12 advance edition of Drug Metabolism and Disposition.

AIDS 2014: Australian Bone Marrow Transplant Patients Show No Detectable HIV

An additional 2 people with long-term HIV infection have no evidence of infectious virus or viral genetic material following bone marrow stem cell transplants to treat leukemia or lymphoma, researchers reported at the 20th International AIDS Conference last month in Melbourne. While these individuals remain on antiretroviral therapy (ART) and therefore cannot be considered functionally cured, they offer further evidence that HIV may be controlled off ART in some cases.

Mississippi Baby and Other Relapsers Hold Lessons for HIV Cure

Despite the disappointment felt by many, the return of detectable HIV in the Mississippi Baby and 2 patients who received bone marrow transplants are of "enormous scientific importance" and indicate that addressing the latent viral reservoir is the major challenge in achieving a cure or long-term remission, according to an editorial in the August 29 edition of Science.

AIDS 2014: Novel Techniques Probed in HIV Cure Research

A pair of presentations at the 20th International AIDS Conference in Melbourne described new pathways being explored in the search for either a permanent cure for HIV or for longer-acting drugs. In one study, 2 artificial genes that cause cells to generate antiviral entry inhibitors produced significant inhibition of cellular infection. In the other, a technique that is the exact opposite of the much-explored "kick and kill" strategy (which uses drugs to activate cells latently infected with HIV) used an artificial gene fragment to maintain latently infected cells in a locked-down state that resisted strong immune stimulation.
