The National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), announced that three scientists have been selected to receive the 2017 Avant-Garde Award for HIV/AIDS research. The winning proposals focus on a variety of novel approaches, including: improving HIV prevention through effective gene therapies; enhancing innate (natural) immunity against HIV and other related viruses; and developing new small-molecule drugs to treat HIV-1 infection. The three scientists will each receive $500,000 per year for five years to support their research, subject to the availability of funds. NIDA's tenth annual Avant-Garde Award competition is intended to stimulate high-impact research that may lead to groundbreaking opportunities for the prevention and treatment of HIV/AIDS in drug users.
“With nearly 37 million people living with HIV worldwide, it is essential that researchers continue to develop effective prevention and treatment strategies for those suffering from this devastating disease, including people with substance use disorders,” said NIDA director Nora D. Volkow, M.D. “These scientists are pioneering exciting new approaches aimed at preventing and treating new cases of HIV and helping people at risk live longer, healthier lives.”
The awardees are:
Michael Farzan, Ph.D., The Scripps Research Institute --Project: A safety switch for an effective HIV-1 vaccine: Dr. Farzan plans to use preclinical models to explore safe and effective gene therapies for the long-term prevention of HIV infection in high-risk populations, such as injection drug users. He will use an adeno-associated virus to deliver broadly neutralizing antibodies (bNAbs) or eCD4-Ig, proteins that prevent HIV-1 from infecting cells. His group will also explore safety switch mechanisms to control bNAbs and eCD4-Ig, thereby increasing safety during long-term exposure to these molecules.
Eric M. Poeschla, Ph.D., University of Colorado Denver --Project: Novel Approaches to Innate Immunity Against HIV-1 and Other Co-infection Viruses: Dr. Poeschla will use animal and human cells to explore the use of viral RNA-dependent RNA polymerase (RdRP) to enhance broad-spectrum (innate) immunity against various viruses, including HIV-1. Evidence suggests that this stable innate immune system activation does not trigger autoimmunity or inflammatory pathways. This approach may also protect against viruses that infect people with addiction.
Peter S. Kim, Ph.D., Stanford University – Project: Making the HIV-1 gp41 pocket amenable to small-molecule drug discovery: Dr. Kim’s group proposes a strategy that alters the HIV-1 gp41 region, thereby increasing structural rigidity in this region. This will enhance testing of new therapeutics that target the gp41 pocket to prevent HIV infection. Because the pocket is structurally similar across different HIV-1 strains, these therapeutics could treat patients, including people with substance use disorders, who are at higher risk of developing resistance to one or more classes of anti-HIV drugs.
The Avant-Garde Awards are modeled after the NIH Pioneer Awards and are granted to scientists of exceptional creativity who propose high-impact research that could open new avenues for prevention and treatment of HIV/AIDS among people with substance use disorders.
Drs. Farzan, Poeschla and Kim are funded under grant numbers DA043912-01, DA043915-01 and DA043893-01, respectively.
The National Institute on Drug Abuse (NIDA) is a component of the National Institutes of Health, US Department of Health and Human Services. NIDA supports most of the world’s research on the health aspects of drug use and addiction. The Institute carries out a large variety of programs to inform policy, improve practice, and advance addiction science.
