Ending HIV will require optimizing treatment and prevention tools, say NIH experts

Commentary emphasizes need to optimally implement current tools and develop new interventions.

Unprecedented biomedical research advances over the past four decades have led to development of “toolkits” of highly effective interventions for preventing and treating HIV.

What

Optimal implementation of existing HIV prevention and treatment tools and continued development of new interventions are essential to ending the HIV pandemic, ľ��ֱ�� experts write in a commentary in Clinical Infectious Diseases.

Today, many highly effective HIV treatment and prevention interventions are available. (ART) not only improves the health and prolongs the lives of people with HIV but also plays an important role in HIV prevention. People living with HIV whose virus is durably suppressed to undetectable levels by ART cannot sexually transmit HIV to others, a concept known as , or U=U. Antiretroviral drugs taken by people without HIV as (PrEP) are highly effective at preventing acquisition of HIV.

Theoretically, the widespread provision of ART and PrEP could end the HIV pandemic. However, a gap exists between theory and reality, write Anthony S. Fauci, M.D., director of NIH’s National Institute of Allergy and Infectious Diseases (NIAID), and colleagues. Implementation gaps exist at all stages of the . Progress in cities like San Francisco, which has dramatically reduced new HIV cases by deploying ART, PrEP and other tools, suggests that these gaps can be overcome. Such examples offer lessons for optimizing implementation strategies. 

Even with the availability of simplified HIV drug regimens, medication adherence remains a challenge for many. Thus, there is a need to develop new treatment and prevention strategies and products that can be efficiently taken up by people from diverse communities. Potentially, these new tools will have improved efficacy and broader uptake due to better acceptability and usability. 

Researchers are pursuing multiple approaches to achieve durable control of HIV without  daily ART, including pursuing a cure that would from the body or keep it at very low levels, and developing and (bNAbs) that could be dosed once every few months or less often. Approaches to optimizing HIV prevention include , , multi-purpose tools for HIV prevention and contraception, and other innovative strategies. Scientists also are working toward development of a safe and effective . Currently, three large HIV vaccine efficacy clinical trials are under way globally.
