Sangamo BioSciences announced yesterday that it is initiating two Phase 2 clinical trials of its gene therapy treatments for people with HIV. The trials will test two different strategies for increasing the effectiveness of the therapy, with the goal of creating a cure for HIV.
“We are delighted to be able to open these two important clinical studies ahead of schedule,” said Geoff Nichol, executive vice president of research and development at Sangamo, in a press release.
Both trials are testing gene therapy approaches to curing HIV. In the field…

This article is the second part of a two-part interview with Dr. Jeffrey Laurence, senior scientific consultant for the Foundation for AIDS Research, on the Foundation’s efforts toward a cure for HIV. Part 1 discusses the possibility of a cure and why it is necessary. Part 2 discusses the Foundation’s cure research and some promising avenues toward a cure.
Thirty years after the start of the AIDS epidemic, scientists and researchers know more than ever about the elusive and difficult-to-treat HIV virus. And, with the first-ever example of a…

Congress Launches Congressional HIV/AIDS Caucus – Five representatives of Congress announced the launch of the Congressional HIV/AIDS Caucus last week. The goals of the Caucus are to maintain U.S. leadership in the fight against HIV and AIDS in the U.S. and internationally and to prepare for the International AIDS Conference in Washington, D.C., next year. The Caucus is co-chaired by Representative Jim McDermott from California, Representative Trent Franks from Arizona, and Representative Barbara Lee from California. It will have 59 members at its launch; additional members are expected to join in the coming weeks. For more information, please see the announcement on the Aids.gov website.
EMA Advisory Committee Recommends Approval For Edurant And Eviplera In Europe – An advisory committee to the European Medicines Agency (EMA) has recommended that Edurant (rilpivirine) be approved for the treatment of HIV in previously untreated adults with viral loads (amount of HIV in the blood) of 100,000 copies per milliliter or less. Edurant is marketed outside the U.S. by the pharmaceutical company Janssen, a unit of Johnson & Johnson. The committee also recommended that Gilead Sciences’ new once-daily combination antiretroviral pill Eviplera (rilpivirine/emtricitabine/tenofovir), known as Complera in the U.S., be approved for the same patient population. The recommendations improve the chances for approval of the drugs in Europe; a decision is expected within two to three months. Edurant was approved in the U.S. in May, and Complera was approved in August. For more information, please see the Johnson & Johnson and Gilead Sciences press releases.
Gene Therapy Successfully Reduces Viral Loads In People With HIV (ICAAC 2011) – Sangamo Biosciences released updated results on its Phase 1 gene therapy clinical trial last Sunday showing that the treatment successfully reduced viral loads (amount of HIV in the blood) in all six of the trial’s participants without the use of antiretroviral drugs. One participant, who had a genetic variation that makes people naturally more resistant to HIV, successfully achieved an undetectable viral load. Sangamo reported no major side effects from the treatment. The results were presented at the 51st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Chicago. Sangamo previously reported that the gene therapy treatment increased CD4 (white blood cell) counts in people with HIV (see related AIDS Beacon news). For more information, please see the Reuters article or the Sangamo Biosciences press release.
Bristol-Myers Squibb Reports 83 Percent Hepatitis C Cure Rate In Phase 2 Study (ICAAC 2011) – Results from a Phase 2 clinical trial indicate that Bristol-Myers Squibb’s investigational hepatitis C drug BMS-790052 yielded an 83 percent cure rate after 48 weeks in previously untreated adults with genotype 1 hepatitis C when combined with peginterferon alfa-2a (Pegasys) plus ribavirin (Copegus, Rebetol). Eight percent of participants reported serious side effects (anemia, or low red blood cell counts). Based on the results, Bristol-Myers Squibb has initiated a Phase 3 clinical trial with the drug. The results were presented last Saturday at ICAAC. For more information, please see the study (abstract) at the ICAAC website or the Bristol-Myers Squibb press release. For more information on the Phase 3 clinical trial, please see the U.S. Clinical Trials Registry.

Is gene therapy too expensive and impractical to form the basis for a cure for HIV, or is it a promising technique with a proven track record that has the specificity required for a cure?
This question was debated by researchers at the 6th International AIDS Society Conference on HIV Pathogenesis, Treatment, and Prevention (IAS 2011) in Rome last month.
Gene therapy is an experimental approach that is currently in early stages of clinical testing. Gene therapy involves modifying a person’s DNA (the genetic information in cells) so that it…

This article is the fourth in a four-part series that investigates current research toward finding a cure for HIV, including advances, promising treatment strategies, and barriers to reaching a cure. Part 1 discusses general types of HIV cures. Part 2 discusses specific strategies for targeting latent HIV. Part 3 discusses gene therapy and therapeutic vaccines. Part 4 discusses barriers to obtaining a cure.
Although researchers are getting closer to finding a cure for HIV and have a number of promising avenues to pursue, there are still a…
