The Avant-Garde Awards promote research in HIV treatment and prevention in drug users.

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.
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.
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.

Three scientists received 2017 Avant-Garde Awards for HIV/AIDS
Research, which highlight novel approaches to HIV prevention and
treatment among drug users. According to a press release
from the National Institute on Drug Abuse (NIDA), each scientist will
receive $500,000 a year for five years for his specific research.
NIDA,
which is part of the National Institutes of Health, grants the awards
as a way to stimulate high-impact research that could lead to
breakthroughs regarding HIV/AIDS among people with substance use
disorders.
“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, MD, in the press release.
“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.”
According to the press release, the awardees and their projects are:
Michael Farzan, PhD, The Scripps Research Institute
Project: A safety switch for an effective HIV-1 vaccine
