February 7th, 2014. 3-6 pm Gladstone Institutes.
First floor conference room A/B - 1650 Owens street San Francisco.

On January 25, 2014, our dear friend and colleague Jeff McConnell died in his apartment in San Francisco at the age of 49. Jeff was one of the pillars of iPrEx which championed Pre-exposure prophylaxis, or PrEP. Jeff McConnell was sensitive to social goals and practices, willing to eschew conventional thinking, and had a relentless intention to stop AIDS. Under Jeff’s guidance, we have a pill that prevents HIV infection, and powerful information about the social and sexual networks of gay men and transgendered women on 4 continents: Asia, Africa, Latin America, and North America.

Circumcision effectively reduces the risk of HIV infection “in real life”

ANRS Project in Orange Farm, South Africa confirms

The ANRS-12126 “Bophelo Pele” Project implemented in the township of Orange Farm in South Africa has confirmed the effectiveness of a large-scale program of voluntary medical male circumcision in prevention of heterosexually acquired HIV infection. The follow-up of over 3300 men shows a 57% to 61% reduction in the rate of new HIV infections in circumcised men compared with uncircumcised men. This study, headed by Prof Bertran Auvert and his colleagues, also shows that a circumcision program can be rapidly and effectively implemented in African communities where circumcision is not a social norm. These results, published in PLoS Medicine, argue for accelerated roll-out of voluntary male circumcision programs on the African continent in order to improve prevention of HIV transmission...

HPTN 073, a New PrEP Demonstration Project is currently enrolling

Study takes place in three US cities

HPTN 073: Pre-Exposure Prophylaxis (PrEP) Initiation and Adherence among Black Men who have Sex with Men (BMSM) is a demonstration study evaluating PrEP initiation and adherence among HIV-negative black men who have sex with men. The study aims to assess the initiation, acceptability, safety, and feasibility of PrEP for black men who have sex with men (BMSM) in three U.S. cities utilizing client-centered care coordination (C4) models. This open label Truvada PrEP study attempts to recruit an equal number of BMSMs under age 25 and over 25, for a total of 225 participants with 75 participants at each of the three sites. The study will take place at three of the US sites of the HIV Prevention Trials Network (HPTN); the University of North Carolina in Chapel Hill; in Washington, D.C., through George Washington University; and through the University of California at Los Angeles. A subset of study participants will also be recruited to participate in qualitative interviews about facilitators and barriers regarding PrEP.

Statement

iPrEx Welcomes CDC’s Bangkok Tenofovir Study Showing Pre-Exposure Prophylaxis (PrEP) is Safe and Effective for HIV Prevention in Injection Drug Users

The following statement was released by iPrEx Protocol Chair Robert Grant, MD, MPH of the Gladstone Institutes and the University of California at San Francisco

Oral PrEP is a critically important HIV prevention tool that can play a significant role in reducing individual infection risk and helping to end the epidemic. Today’s news, that PrEP prevents HIV among people whose primary infection risk is injection drug use, adds to clear evidence from earlier studies that PrEP is safe and effective at preventing the sexual transmission of HIV in gay and bisexual men and in heterosexual women and men. With this new evidence we now know that PrEP, which was FDA-approved to prevent sexual transmission of HIV in 2012, can help HIV-uninfected people protect themselves from HIV regardless of the route of exposure...

A New PrEP Study in Men Who Have Sex with Men is currently Recruiting Participants in England 500 MSM will be participating in this PrEP study.

The "PROUD study: Examining the impact on gay men of using Pre-Exposure Prophylaxis (PrEP)", is a new PrEP study that started enrollment of MSM participants in November of 2012 in six cities across England.
The PROUD trial is a two-year study that will recruit volunteers across England, who will be placed at random into one of two groups. One group will use PrEP from the start of the study, and the other group will receive PrEP after 12 months. Both groups will receive support to remain HIV negative throughout the study. The study medication used in this PrEP study is Truvada (which contains tenofovir and emtricitabine) the same medication that was used in the iPrEx study.

The trial will be recruiting 500 men who have sex with men in 14 study sites in England that include the following cities: London, Brighton, Birmingham, York, Manchester and Sheffield. Enrollment criteria includes:
• Be HIV negative
• 18 years of age or older
• Have had anal sex without a condom in the last three months.
• Be likely to do this again in the following three months.
• Be able to visit the study clinic for blood tests every three months.

This study is looking at a new way to reduce the risk of getting HIV. It will look at the impact of taking PrEP on how often men have sex; how often they use condoms; and whether they get other sexually transmitted infections. The study is sponsored by the UK Medical Research Council Clinical Trials Unit, and study drug and support for protocol specific procedures and laboratory tests have been provided by Gilead Sciences.

An open-label, pilot demonstration and evaluation project of antiretroviral-based HIV-1 prevention among high-risk HIV-1 serodiscordant African couples.

The Partners Demonstration Project

Antiretroviral-based HIV-1 prevention strategies – including antiretroviral treatment (ART) to reduce the infectiousness of HIV-1 infected persons and pre-exposure prophylaxis (PrEP) for uninfected persons to prevent HIV-1 acquisition – are among the most promising new approaches for dramatically decreasing HIV-1 spread. A priority population for implementation of ART and PrEP for HIV-1 prevention is HIV-1 serodiscordant couples (i.e., one member is HIV-1 infected and the other uninfected).
Stable, heterosexual African HIV-1 serodiscordant couples face high risk of HIV-1 transmission, from within the partnership and from outside partners, and are a priority population for prevention interventions.

PrEP Interim Guidance for PrEP in Sexually Active Heterosexual Adults

CDC released today

In the United States, an estimated 48,100 new human immunodeficiency virus (HIV) infections occurred in 2009 (1). Of these, 27% were in heterosexual men and women who did not inject drugs, and 64% were in men who have sex with men
(MSM), including 3% in MSM who inject drugs. In January
2011, following publication of evidence of safety and efficacy
of daily oral tenofovir disoproxil fumarate 300 mg (TDF)/
emtricitabine 200 mg (FTC) (Truvada, Gilead Sciences) as
antiretroviral preexposure prophylaxis (PrEP) to reduce the risk
for HIV acquisition among MSM in the iPrEx trial, CDC issued
interim guidance to make available information and important
initial cautions on the use of PrEP in this population. Those
recommendations remain valid for MSM, including MSM
who also have sex with women (2). Since January 2011, data
from studies of PrEP among heterosexual men and women have
become available, and on July 16, 2012, the Food and Drug
Administration (FDA) approved a label indication for reduction
of risk for sexual acquisition of HIV infection among adults,
including both heterosexuals and MSM.* This interim guidance
includes consideration of the new information and addresses
pregnancy and safety issues for heterosexually active adults at
very high risk for sexual HIV acquisition that were not discussed
in the previous interim guidance for the use of PrEP in MSM.

World Health Organization issues first PrEP guidance

Guidance is issued after FDA approved Truvada for PrEP on July 16th

20 JULY 2012 | GENEVA / WASHINGTON DC - WHO has issued its first guidance to countries that are considering offering HIV medications, known as antiretrovirals (ARVs), to protect people who do not have the virus but who are at high risk of HIV infection.

Pre-exposure prophylaxis (PrEP)
The guidance is based on clinical trials indicating that a daily dose of oral antiretroviral medication, known as pre-exposure prophylaxis (PrEP), taken by HIV-negative people to reduce the risk of infection, is both safe for people to use and effective in preventing HIV. The iPrEX study shows that use of PrEP can reduce HIV infection by around 40% among men who have sex with men – and up to 73% among those who took the medicine regularly. The Partners PrEP study found 75% protection among serodiscordant couples (couples in which one person is HIV positive) in Kenya and Uganda.

Southern African guidelines for the safe use of pre-exposure prophylaxis in men who have sex with men who are at risk for HIV infection

Southern African Journal of HIV Medicine, Vol 13, No 2 (2012)

Abstract

Background. The use of oral antiretrovirals to prevent HIV infection among HIV-negative men who have sex with men (MSM) has been shown to be safe and efficacious. A large, randomised, placebo-controlled trial showed a 44% reduction in the incidence of HIV infection among MSM receiving a daily oral fixed-dose combination of tenofovir disoproxil fumarate and emtricitabine (Truvada) in combination with an HIV prevention package. Improved protection was seen with higher levels of adherence.

Aim. The purpose of this guideline is to: (i) explain what pre-exposure prophylaxis (PrEP) is; (ii) outline current indications for its use; (iii) outline steps for appropriate client selection; and (iv) provide guidance for monitoring and maintaining clients on PrEP.

Method. PrEP is indicated for HIV-negative MSM who are assessed to be at high risk for HIV acquisition and who are willing and motivated to use PrEP as part of a package of HIV prevention services (including condoms, lubrication, sexually transmitted infection (STI) management and risk reduction counselling).

FDA Antiviral Drugs Advisory Committee Recommends New Indication of
FTC/TDF for HIV Prevention

The following statement is released by Robert Grant, MD, MPH, of the Gladstone Institutes and the University of California San Francisco

In a public hearing at the FDA White Oak Campus, the FDA Antiviral Drugs Advisory Committee voted in favor of recommending the change in indication of the antiretroviral
drug combination emtricitabine/tenofovir disoproxil fumarate (Truvada®) for the prevention of HIV infection in adults as pre-exposure prophylaxis.

On December 15th, 2011, Gilead Sciences Inc., the manufacturer of Truvada, filed a "supplemental new drug application (sNDA)" with the US Food and Drug Administration
(FDA) proposing a change in its indication based on the efficacy and safety results from the iPrEx and Partners PrEP studies. Truvada is currently used as a treatment for HIVinfected individuals.

As part of this process, Gilead Sciences, iPrEx and Partners PrEP have been providing the FDA with all the necessary information so that the FDA can make an evidencebased decision regarding the prevention use of Truvada. For advice, and to help make
a decision, the FDA convened an Antiviral Drugs Advisory Committee comprised of experts in the field as well as a consumer representative. This committee reviews the data and formulates recommendations, however, the final decision will be made by the FDA.

Questions and Answers

iPrEx and the Supplemental New Drug Application of Truvada for Pre-Exposure Prophylaxis

What is an Investigational New Drug Application (IND)?
An IND is a request for authorization from the US Food and Drug Administration (FDA) to administer an investigational drug or biological product to humans. A physician might submit a research IND to propose studying an unapproved drug, or an approved product for a new indication or in a new patient population.  An IND application includes animal pharmacology and toxicology study data, manufacturing information and clinical protocols and investigator information.


Was the study medication used in iPrEx, tenofovir disoproxil fumarate and emtricitabine (Truvada®), filed as an IND with the FDA?

Yes, the iPrEx study has an IND filing with the FDA. The study sponsor, the National Institute of Allergies and Infectious Diseases (NIAID)/Division of AIDS (DAIDS), holds the IND. By filing an IND, the IND holder commits to keeping the FDA informed about the conduct of the study. That is, evaluating the drug and reporting any adverse experiences or changes in the study conduct.

These audits took place as part of the supplemental New Drug Application (sNDA) of oral daily Truvada® for HIV prevention, that Gilead Sciences, filed with the FDA last December. The FDA auditor found no critical
issues in the implementation of the study in either study site.

CDC "Project T" Participants to Join iPrEx

iPrEx OLE will invite 279 additional participants from the US Centers for Disease Control and Prevention (CDC)'s long-term PrEP safety study, Project T (http://helpfighthiv.org/projt.htm), to join the roll over phase of the iPrEx study.
Project T sites in in San Francisco and Boston will contact participants and host information sessions to explain the iPrEx study results and inform Project T participants of their eligibility to enroll in iPrEx OLE (Open Label Extension). Adding Project T participants will strengthen iPrEx OLE while providing HIV-negative Project T participants who chose to enroll with an additional 72 weeks of access to PrEP with Truvada (emticitabine/tenofovir). Truvada PrEP has proven to be up to 92% effective in preventing HIV infection in men who have sex with men (MSM) with regular use.
Project T tested the long-term safety of tenofovir, a frequently prescribed HIV therapy, in HIV-negative men MSM over a two-year period. Study results, first presented in July of 2010 at the XVIII International AIDS Conference in Vienna, Austria found no significant safety concerns with taking a daily tenofovir pill. The study also found that men in the trial did not take more risks sexually while taking tenofovir.
The study was conducted by the U.S. CDC in collaboration with the San Francisco Department of Public Health, AIDS Research Consortium of Atlanta and Fenway Health in Boston.

PrEP Demonstration Project in San Francisco, California

San Francisco will be the first city in the United States to implement a pre-exposure prophylaxis (PrEP) demonstration project in men who have sex with men (MSM).
With support from the US National Institutes of Health (NIH), the San Francisco Department of Public Health is planning to launch a demonstration project of PrEP for HIV prevention using the ARV combination tenofovir/emtricitabine, commercially known as Truvada®. This is the same medication used in the iPrEx trial that proved to be up to 92% effective in the prevention of HIV infection in MSM in the iPrEx study.
Pending final approval, this pilot intervention will enroll 300 MSM at sites that include the City Clinic and Magnet, a gay men's health center in the Castro neighborhood.
The San Francisco Department of Public Health has been an important site in the iPrEx trial. The Department of Health was the first site to open enrollment in iPrEx OLE, a 72 week Open Label Extension of the iPrEx study designed to collect additional information about long-term safety and efficacy of PrEP and sexual behavior of participants taking the daily HIV prevention pill.

iPrEx OLE to Build on News that PrEP Slows HIV Infections Significantly in Both Men Who Have Sex with Men and Heterosexual Women and Men

The iPrEx Open-Label Extension Study (iPrEx OLE), the next phase of the first human study to report efficacy results on pre-exposure prophylaxis (PrEP) to prevent HIV infection, has begun at clinical trial sites around the world. Approximately 2,000 men and transgender women who have sex with men are expected to participate in the 72-week iPrEx OLE study (http://www.iprexole.com/). Study sites in the United States and South Africa are enrolling participants now, as other study sites finalize the regulatory approval process.

In PrEP, antiretroviral medications that are usually used to treat HIV are taken by uninfected people to reduce their risk of infection. The iPrEx study found that men and transgender women who have sex with men (MSM) who took a single daily tablet containing the HIV medications emtricitabine and tenofovir (FTC/TDF), known commercially as Truvada®, experienced an average of 44% fewer HIV infections than those who received a placebo (blank pill). HIV infection rates in the iPrEx study dropped by 90% among those who used PrEP consistently enough to have detectable drug in the body. The HIV risk reduction benefits of PrEP were in...

"Today's news from the Partners PrEP and CDC Botswana (TDF2) studies detailing the safety and effectiveness of PrEP in heterosexual women and men is a major step forward in HIV prevention research with global implications for helping to end the AIDS epidemic.

PrEP involves uninfected people taking antiretroviral medications, which are usually used to treat HIV, to reduce their chances of HIV infection. With 2.6 million people worldwide newly infected by HIV each year, the compelling evidence presented by the iPrEx, Partners PrEP and TDF 2 studies -- that PrEP greatly reduces the risk of HIV infection both in heterosexual men and women and among men who have sex with men -- makes it increasingly clear that PrEP can play an important role in helping to slow the global epidemic in multiple populations at ...

Science Speaks: HIV & TB News

Ready to launch: "ADAPT" study looks at intermittent dosing of PrEP

Investigators at the HIV Prevention Trials Network (HPTN) Annual Meeting Monday received an update on a study looking to ease the pill burden on those wishing to benefit from pre-exposure prophylaxis (PrEP).

Inspired by studies of non-human primates over the past seven years at the Centers for Disease Control and Prevention, the HPTN 067 "ADAPT" study (Alternate Dosing to Augment PrEP Tablet-taking) is a behavioral study looking at how adherence can be improved by lowering the frequency and potency of each dose, while achieving "comparable" efficacy in preventing HIV infection.

The primate studies, "…Encourage us that daily doses might not be necessary, and easier dosing that is better adaptable to people may be possible," said Bob Grant, MD, of the Gladstone Institute of Virology and Immunology in San Francisco, who presented on the study. The idea of adapting PrEP regimens to the patients' needs was well-received by the audience, and Grant said it was a key concept to improving adherence, "especially in terms of people whose lives are not defined by a disease they don't have."

HPTN 052

Statement from the iPrEx Pre-Exposure Prophylaxis Study on Results of the HPTN 052 HIV Prevention Study

Dowload Statement

The following statement was issued today by iPrEx Protocol Chair Robert Grant, MD, MPH of the Gladstone Institutes and the University of California at San Francisco:

“iPrEx congratulates the participants and researchers involved in HPTN 052.  This important study proves that providing early antiretroviral treatment significantly improves health among people living with HIV and dramatically reduces new HIV infections in their partners.

HPTN 052 adds another piece of compelling evidence that the HIV epidemic can be slowed and one day stopped.  In less than two years, we have seen significant new discoveries supporting the use of treatment as prevention, including early treatment of HIV infected persons, oral pre-exposure prophylaxis (PrEP) for uninfected men who have sex with men (MSM), and topical pre-exposure prophylaxis for uninfected heterosexual women.  In the previous few years, we learned that heterosexual men can be durably protected by male circumcision, and injection drug users are protected by clean needles.  Mother to infant transmission has nearly vanished in places where antiretroviral therapy is available for pregnant women.  An HIV vaccine candidate showed promising preliminary results.  The risk behavior of participants in these studies became consistently safer overtime, signaling the compatibility of each of these prevention approaches with behavioral risk reduction strategies.

Never before have so many effective HIV prevention tools and strategies been available.  The challenge before funders and policy makers now is to increase investments to make new HIV treatment and prevention tools available to everyone who needs them, along with standard prevention methods such as male and female condoms, HIV testing and counseling, STD treatment and support for behavioral prevention approaches.

Investments to date in HIV prevention research have brought tremendous results.  HIV can be slowed and one day stopped if we use this new information.  The funds required to fight and win the war on HIV are substantial, although in line with other investments made to assure public safety and relieve widespread human suffering.  Increasing investment in HIV prevention will save millions of lives, increase productivity and savings and build stronger and safer communities.  Now is the time to invest in a future without AIDS.”

 

 

FEM-PrEP trial

iPrEx Statement on the Discontinuation of the FEM-PrEP HIV Prevention Study

iPrEx FEM PrEP Q&A

The Independent Data Monitoring Committee (IDMC) overseeing the FEM-PrEP study of oral pre-exposure prophylaxis (PrEP) (http://www.fhi.org) has recommended that the study be
stopped because it will not be able to answer the question of whether the HIV antiretroviral drug Truvada can decrease HIV infection risk in heterosexual women.

In November 2010, results from the Global iPrEx study (http://www.iprexnews.com) showed robust and highly statistically significant evidence that daily use of the same medication does reduce HIV infection risk among men who have sex with men (MSM). PrEP with Truvada in the iPrEx study reduced HIV infection risk among all MSM by an average of 44%. HIV infection rates were 90% lower among those who used Truvada consistently enough to have detectable drug in the body.

In addition, the effectiveness of a vaginal topical formulation of one of the component drugs of Truvada, tenofovir, was also demonstrated in a study of heterosexual women in Africa,
CAPRISA 004, which announced results in July 2010. The topical formulation of tenofovir is known to achieve high levels of drug in the vagina when used consistently by women.

The evidence that oral PrEP with Truvada significantly reduces HIV infection risk in MSM is clear. More study, including analysis of drug levels and adherence among study participants, is
needed to understand the results of FEM-PrEP. Whether the difference in results between studies is attributable to differences in the biological activity of the drug in men and women, its
effectiveness at reducing infection risk based on different routes of HIV exposure or other factors such as pill use are yet to be determined. These questions will be a central focus of inquiry for the HIV prevention research community moving forward, and the answers will help us understand the best and most appropriate uses for oral PrEP as HIV prevention. The VOICE
and Partners PrEP trials being conducted in African women and men are also expected to provide important additional information on the safety and efficacy of PrEP in heterosexual
populations.

Worldwide, 2.6 million people were infected with HIV last year alone. MSM are 19.3 times more likely to become infected with HIV than non-MSM, pointing out the need for effective new
strategies to reduce HIV infection risk among MSM.

A multi-country open label extension of the iPrEx study called iPrEx OLE is beginning in MSM the coming months in the United States, Peru, Ecuador, Brazil, Thailand and South Africa. All participants in iPrEx OLE will be able to receive Truvada in tablet form, in addition to other proven HIV prevention tools such as condoms, treatment for sexually transmitted infections and HIV testing and counseling. In addition to gathering more safety data on PrEP, iPrEx OLE will focus on strategies to help participants take PrEP consistently.

HIV is transmitted differently in different populations and settings, and effective HIV prevention will never be a "one size fits all" model. FEM-PrEP demonstrates the importance of studying promising HIV prevention interventions in different populations. The study will add valuable information that will help determine the best use of PrEP as an important new tool to slow the global HIV epidemic. We commend everyone involved in the FEM-PrEP study – most importantly the women who participated – on their work to advance HIV prevention research,
and look forward to working closely with them to better understand the results of this study.

Interim Guidance: Pre-exposure prophylaxis (PrEP) for the prevention of HIV infection in men who have sex with men

Download Interim Guidance

CDC issues interim guidance to health care providers on the use of PrEP as an HIV prevention strategy among men who have sex with men (MSM). In November 2010, the National Institutes of Health announced trial results providing the first evidence that daily oral use of an antiretroviral drug (TDF/FTC, brand name Truvada) used to treat HIV can also help to prevent sexually-acquired HIV among MSM when delivered as a part of comprehensive HIV prevention services. To help ensure safe and effective use of PrEP, CDC is currently leading national efforts to develop formal U.S. Public Health Service guidelines on its use among MSM. Until those more detailed guidelines are available, CDC is providing interim guidance to help inform clinical practice. CDC underscores the importance of targeting PrEP to MSM at high-risk for HIV acquisition and delivering it as a part of comprehensive HIV prevention services, which should include risk-reduction and medication adherence counseling, condoms, and testing and treatment for other sexually-transmitted infections. The guidance stresses the need to ensure any MSM who may be prescribed PrEP are confirmed to be HIV negative prior to use, as well as the need for regular monitoring of HIV status, side effects, adherence, and risk behavior among those taking PrEP. The guidelines only apply to MSM, as no data are available on its effectiveness among other populations.
