Magee-Womens Research Institute Receives $17.5 million
for Rectal Microbicide ResearchDr. Ian McGowan* (pictured below), 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.
