Rectal microbicide research gives hope for HIV protection

via Citizens News Service, by Somya Arora

According to the Microbicides Trials Network (MTN), HIV continues to disproportionately affect racial minorities and men who have sex with men (MSM). MTN estimates that 5 to 10 percent of the world’s population engages in anal sex and globally, MSM are 19 times more likely to be infected with HIV than the general population. Unprotected anal sex is the primary driver of the HIV epidemic among this population. The risk of becoming infected with HIV during unprotected anal sex is 10 to 20 times greater than unprotected vaginal sex, because the rectal lining being only one-cell thick, it allows the virus to easily reach immune cells to infect. 

“Rectal microbicides are critical to turn the tide of the AIDS pandemic as we know that unprotected anal intercourse is the riskiest of HIV related behaviours. Human beings, all over the world, regardless of gender and sexuality, have anal intercourse and a lot of this is unprotected because they do not have access to condoms and/or because of the mistaken notion that anal intercourse is safer than vaginal intercourse with regards to contracting HIV. Having more tools for protection, in addition to what we already have, I think would be absolutely critical,” says Jim Pickett, Director (Advocacy), Chicago AIDS Foundation and founder-chair of International Rectal Microbicide Advocates (IRMA).

In an update on the CHARM (Combination HIV Antiretroviral Rectal Microbicide) Program, Dr Ian McGowan, Professor of Medicine, University of Pittsburgh, and Co-principal Investigator MTN, informs that, “Microbicides are products that can be applied to the vaginal or rectal mucosa with the intent of preventing or significantly reducing the risk of acquiring Sexually Transmitted Infections including HIV. Combination antiretrovirals are more potent and more useful as rectal microbicides. The rationale behind the CHARM programme is that we need a rectal specific combination antiretroviral microbicide.”

Did you miss the IRMA/AVAC teleconference on the CHARM program? You're in luck...

The teleconference I am referring to – “And in the beginning, there were Rectal Microbicides” – was held last Thursday. The slides and call recording are available now.

It was a really interesting call – with LOTS of great questions from the participants. Thanks to everyone who made it so dynamic – including presenter Ian McGowan and all the folks who asked really important questions.

Click here for the presentation slides. Click here the call recording.

In this call, Ian McGowan, co-principal investigator of the Microbicide Trials Network and Principal Investigator of CHARM (the Combination HIV Antiretroviral Rectal Microbicide Program) provided an update on what is happening with this innovative program.


Funded by the U.S. National Institutes of Health in 2009, CHARM is an $11 million, five year, multicenter grant intended to advance candidate rectal microbicides from discovery into early clinical development. Rather than simply testing existing vaginal formulations of microbicides, CHARM seeks to develop rectal-specific products from the beginning.

$17 million grant to help Pitt researcher develop anti-HIV gel

via Pittsburgh Post-Gazette, by David Templeton

Highlight:

Dr. McGowan said the size of the NIH grants reflects a change in Washington, D.C., where the Obama administration has shown greater interest in funding HIV-prevention research.

"The Bush administration had a very high level of discomfort embracing HIV prevention research in men," he said. "But I think in the Obama administration that's a non-issue. They regard domestic HIV prevention in men who have sex with men as an important research priority."

It also reflects growing awareness that not only men have anal sex.

"There's increasing evidence that men and women have anal sex, too," he said. "If we are interested in HIV prevention, we have to look at options for both men and women."

Pitt Receives Grants Totaling $17.5 million for Two HIV Prevention Projects: Multicenter Studies Will Develop Rectal Microbicides and Assess Their Acceptance

via Erie Gay News

A multicenter research team led by the University of Pittsburgh is developing microbicides specifically designed to prevent rectal transmission of HIV, with the further aim of assessing their safety and efficacy in lab and early clinical studies.

Funded by an $11 million, five-year grant from the National Institutes of Health, the Combination HIV Antiretroviral Rectal Microbicide (CHARM) program includes a project that will reformulate existing antiretroviral drugs into topical preparations that can be applied to the rectum, said principal investigator Ian McGowan, M.D., Ph.D., a professor of medicine and of obstetrics, gynecology and reproductive sciences at the University of Pittsburgh School of Medicine and an investigator at the Magee-Womens Research Institute.

“Unprotected receptive anal intercourse is the highest-risk sexual activity for HIV transmission,” Dr. McGowan noted. “Vaginal microbicides already are being extensively studied, and a similar approach might be a very effective way of preventing rectal HIV transmission. It will be critical to determine whether vaginal microbicides are safe and effective when used in the rectum, and also to develop rectal-specific products.”

Magee-Womens Research Institute Receives $17.5 million for Rectal Microbicide Research

Dr. Ian McGowan* (pictured), an investigator with the Magee-Womens Research Institute (MWRI), recently received a total of $17.5 million from the National Institutes of Health (NIH) to conduct two studies involving the development of rectal microbicides.

"This is exciting for the field of HIV prevention research, and especially important in terms of moving the research and development of rectal microbicides forward," said McGowan. "We applaud the leadership and vision of our sponsors at the NIH."

Microbicides are topical products that can be applied to the rectal or vaginal mucosa with the intent of preventing, or at least significantly reducing the risk of HIV acquisition in either compartment.

Recognizing the fact that women in the developed and developing world are at risk of HIV infection through anal and vaginal intercourse, the Microbicide Trials Network (MTN), based at MWRI, is currently evaluating the rectal safety of microbicides designed for vaginal use.

Dr. McGowan’s new studies focus the research towards developing microbicide products specifically designed for rectal use.

The first grant is entitled the Combination HIV Antiretroviral Rectal Microbicides or CHARM program. This is an $11 million, five year, multicenter U19 grant that brings together research groups from the University of Pittsburgh, University of North Carolina, Johns Hopkins Medical School, CONRAD, and the University of California at Los Angeles. The U19 grant is part of the NIH funded Integrated Preclinical Clinical Program and is intended to advance candidate microbicides from discovery into early clinical development.

The second grant is a $6.5 million, four year, R01 grant entitled Microbicide Safety and Acceptability in Young Men with Dr. Alex Carballo-Dieguez as the Co-Principal Investigator. The focus of this grant is to evaluate the safety and acceptability of rectal microbicides in young, ethnic minority men who have sex with men (MSM). Funding for this study comes from the National Institute of Child Health and Human Development as well as the National Institute of Mental Health and will generate critical data from a population of young African American and Latino men who are at the highest risk of HIV infection in the United States. Clinical trial sites will be in Pittsburgh, Boston, and Puerto Rico.

"We need to develop safe, effective, acceptable and accessible rectal microbicides for the millions of women and men worldwide who need options beyond condoms," said Jim Pickett, chair of the International Rectal Microbicide Advocates (IRMA) said. "Our global network of advocates, scientists, policy makers and funders is encouraged to see this work moving forward."

Together with ongoing MTN rectal safety studies and another collaborative grant with the University of Oxford, UK, these two new grants establish MWRI as a leading center for rectal microbicide translational research and will hopefully lead to the development of safe and effective products for individuals at risk of HIV infection through unprotected receptive anal sex.
