Research Roundup: What we’re reading this week

On the second day of the XIX International AIDS Conference, the need for a host of new tools to prevent and treat HIV and AIDS has already made it to the forefront of the agenda. Of particular note has been the resounding call for a vaccine to prevent HIV, with leading policymakers, scientists, and advocates saying that the world will never reach the end of AIDS without this powerful tool. In a session that focused on improving the effectiveness and efficacy in the HIV and AIDS response, Senator Lindsey Graham (R-SC) said that a vaccine is desperately needed to help make a sizable dent in the pandemic. Graham’s call for a vaccine was echoed by Bill Gates from the Bill & Melinda Gates Foundation. The “ultimate tool” in the fight against HIV and AIDS “will be a vaccine,” Gates said, adding that the US government has been the largest supporter of efforts to develop and vaccine “by far.” He also said that microbicide gels and rings will be powerful prevention products. Without a number of these new tools, the world cannot “talk seriously about moving toward the end” of the pandemic. “We will get these tools, but only if we stay the course.” Later in the afternoon, National Institutes of Health (NIH) Director Francis Collins and Jon Cohen from Science magazine chaired a panel that looked at what lies ahead in HIV and AIDS science. Gary Nabel, director of the NIH’s Vaccine Research Center, said “we’ve never been in a more exciting position” in the search for an HIV and AIDS vaccine. He added that recent discoveries related to broadly neutralizing antibodies over the past two years have made HIV vaccine research “like a phoenix rising from the ashes.” When sharing their hopes for the status of HIV and AIDS research, several panelists also stressed the urgent need to develop new HIV prevention and treatment options. Nabel said that by 2020, he expects researchers will be “in the midst of efficacy trials for an HIV vaccine candidate.” Robert Siliciano of the Johns Hopkins University School of Medicine stressed that by 2020, scientists will be leading clinical trials for new drugs that attack HIV reservoirs. And Dawn Averitt-Bridge of the Well Project said that by 2020, she hopes the world has effective microbicides to prevent HIV, a functional cure for the disease, and that “research makes it into the lives of the people and families we all care so much about.” Cohen ended the session with a call for young people to become the “next generation of scientists” leading HIV and AIDS research. “I’m looking to the young people, because that’s where the revolution is going to happen.” Kim Lufkin is the GHTC’s communications officer.

In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week. GHTC member the American Foundation for AIDS Research has issued a brief analyzing the human impact that widespread budget cuts, or sequestration, would have on US-funded global health programs. The brief concludes that a “proportionate cut in US Global Health Initiative funding through sequestration would have minimal impact on deficit reduction … The human impact of such cuts in US investments, however, would be devastating.” The director of the National Institutes of Health (NIH), Francis Collins, also discussed the effect of sequestration on biomedical research. He testified before the Health Subcommittee of the Energy and Commerce Committee, saying that sequestration “could do serious damage to the progress that we now see in medical research [at the NIH].” The European Medicines Agency has issued a recommendation that the Hexaxim childhood vaccine is safe for use outside of the European Union. Developed by Sanofi, the vaccine offers protection against six World Health Organization priority diseases. A recent article in USA Today looks at the potential of a widely used HIV/AIDS drug, Truvada, as a possible tool to prevent HIV transmission. In an effort to make foreign assistance more transparent, the US Agency for International Development has made its foreign assistance obligation and expenditure data available online on the Foreign Assistance Dashboard. An experimental four-in-one HIV and AIDS drug called Quad is found to be safe and effective after going through a three-phase clinical process. The Lancet published the research following a recommendation in May by a US Food and Drug Administration (FDA) advisory panel to approve Quad for previously untreated adults infected with HIV-1. A final decision is expected from the FDA by August.
