8th International Conference on HIV Treatment and Prevention Adherence

Miami Beach, Florida - USA, 2-4 June 2013 - Link to conference page

The goal of the 8th International Conference on HIV Treatment and Prevention Adherence is to provide an international forum for the presentation and discussion of state-of-the-science HIV treatment and biomedical prevention adherence research, as well as current behavioral and clinical perspectives in practicum. Our ultimate hope is that this dialogue translates into evidence-based implementation of approaches for real world clinical and community settings.

OBJECTIVES

After attending this conference, participants will be able to:
• Identify successes and challenges in HIV treatment adherence in various settings and populations worldwide
• Explain behavioral and clinical aspects of adherence that reflect a variety of HIV treatment team perspectives (e.g., patients, physicians, physician assistants, pharmacists, nurses, mental health professionals, adherence specialists)
• Describe current perspectives on biomedical HIV prevention interventions, including pre-exposure prophylaxis [PrEP], and antiretroviral-based microbicides
• Discuss the implications of HIV treatment and biomedical prevention adherence for individual, community, and public health
• Identify adherence assessment tools and interventions that can be integrated into patient care and/or as components of prevention interventions

Abstracts

• Developing and implementing a mobile health (mHealth) adherence support system for HIV-uninfected men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP): the iText Study

Miami Beach, Florida - USA, 5-6 June 2013

The Behavioral Science Working Group members and the 2013 Meeting Steering Committee are identifying key behavioral science concerns and challenges faced by the NIH HIV/AIDS clinical trial networks. The meeting will consider the following topics:

· Behavioral economics: Conditional cash transfer and economic incentives to enhance HIV treatment and prevention, etc.
· Addressing the syndemic causes of risk and non-adherence: Exploring the interplay between risk and adherence, strategies to promote adherence and minimize risk compensation, adherence to ART and PrEP intervention approaches, marketing of approved interventions, etc.
· Exploring the limits of “validation”: Questions around transferability, challenges with self-report, complimentary assessments, (e.g., PK data), etc.

The meeting will also be addressing “Prevention interventions for high-risk youth: lessons learned, different needs across study populations, regulatory challenges, etc.” with the Youth Prevention Research Working Group which will meet at the end of the BSWG discussions.

Abstracts

10th International Conference on Biospsychosocial Aspects of HIV Infection
Santa Fe, New Mexico, September 12th - 15th, 2011

The Focus of AIDS IMPACT is to create a network between biological, psychological and social aspects of HIV.
The Conference will connect researchers, practitioners and users to share knowledge, resources, innovations and new ideas.
AIDS IMPACT provides a multi-disciplinary and cross-cultural forum to allow research to inform practice and deliver expertise to where it is needed most, as strategies and methods of treatment, intervention, prevention and care.
The Conference is an excellent opportunity for people working and living with HIV disease, throughout the world to engage in dialogue and debate.

Abstract

Session 20.1, Pedro Goicochea: The iPrEx Trial: A Case Study

The field of pre-exposure prophylaxis (PrEP) trials has always been controversial. Now, after three trials showing efficacy in different populations, the controversy continues to exist. This session will present a brief history of the conduct of the iPrEx trial, the first PrEP trial to show the efficacy of PrEP for HIV prevention as a case study.
The iPrEx study or PrEP Initiative stands for Chemoprophylaxis for HIV Prevention in Men, a trial that showed, in November 2010, that PrEP with FTC/TDF provides 44% additional protection from HIV infection; and is the first and only clinical study in gay men, transgender women and other men who have sex with men at high risk of acquiring HIV.
The iPrEx trial was conducted at 11 sites in six countries on four continents after three years of preparation and broad consultation with the community, national authorities and other stakeholders following good participatory practices (GPP) and ethical principles in biomedical research as recommended by UNAIDS/WHO.
The iPrEx trial is rolling over participants on an open label extension observational study where participants will receive active FTC/TDF for 72 weeks and this will be an opportunity to assess if adherence and drug exposure increase when participants know about safety and efficacy of the PrEP; and if sexual behavior changes.

Men who have sex with men at risk for HIV infection were enrolled in the iPrEx trial of pre-exposure prophylaxis. 2499 HIV-seronegative men or transgender women who have sex with men received a combination of two oral antiretroviral drugs, emtricitabine and tenofovir disoproxil fumarate (FTC–TDF), or placebo. 100 study participants became infected during the follow-up period (36 in the FTC–TDF group and 64 in the placebo group), indicating a 44% reduction in the incidence of HIV. Oral FTC–TDF provided protection against the acquisition of HIV infection among these subjects (Grant et al, NEJM 2010). This population provided a unique opportunity to explore potential immunological correlates that may contribute to protection against acquisition of HIV. Previous case studies have reported on types of immunity which may be associated with such protection in exposed but uninfected individuals. We performed an analysis of HIV-specific cell mediated immunity in participants enrolled in the iPrEx trial using a standard IFN-γ ELISPOT assay. We hypothesized that exposure to HIV before enrollment and during the study period could have stimulated immune responses which protected against HIV acquisition. Individuals who remained seronegative in the iPrEx trial had stronger anti-HIV T cell responses than the responses in the pre-infection period of those who eventually seroconverted, mean of 296 vs 48 SFU/106 PBMC respectively, p<0.00001, and a greater breadth of responses. Strong and broad HIV-specific immune responses are a correlate of protection from acquisition of HIV in the iPrEx trial.

 

 

51th ICAAC: Interscience Conference on Antimicrobial Agents and Chemotherapy Meeting
Chicago, IL, September 16th -20th, 2011

Join 10,000 of your colleagues from around the world at the world's premier meeting on infectious diseases and antimicrobial agents. This fall, world renowned scientists will converge in Chicago to exchange information and foster global solutions to scientific challenges such as HIV/AIDS, anthrax, smallpox, SARS, bioterrorism preparedness, recognition, detections, and medical treatments. Through abstracts, symposia, and other educational opportunities ICAAC will provide timely information that will improve healthcare and the management of infectious diseases.
