Antibody-based Contraceptive Research Center Awarded to Boston University Led Consortium
SAN DIEGO - Oct. 17, 2018 - PRLog -- Investigators from Boston University School of Medicine and Mapp Biopharmaceutical Inc. are heading up a new Contraceptive Research Center (CRC) funded by an $8M grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (1U54HD096957)
The World Health Organization estimates that 40 percent of pregnancies worldwide are unintended, indicating an unmet need for safe, acceptable, and inexpensive contraceptive methods. Although a large number of hormonal methods are commercially available, approximately half of women using contraception have concerns about using hormonal contraceptives. In addition, there are a large number of sexually transmitted infections (STI) indicating an additional unmet need.
Monoclonal antibodies, because of their versatility, specificity, and safety profile, are promising candidates for multipurpose prevention technology (MPTs) that block pregnancy and STIs. "In the future, a human contraceptive antibody could be used alone or in combination with antibodies directed against sexually transmitted pathogens, to enhance the acceptability, efficacy, and marketability of contraceptive MPT products," said Prof. Deborah Anderson of Boston University School of Medicine, one of the CRC leaders. The consortium previously developed and clinically evaluated MB66, a vaginal film that contained monoclonal antibodies against Herpes Simplex Virus and HIV.
The CRC is led by Deborah Anderson, Ph.D. (Boston University School of Medicine, Boston, MA; Administrative Lead), Kevin Whaley, Ph.D. (Mapp, San Diego CA), and Thomas Moench, M.D. (Mapp and Mucommune, Chapel Hill NC), and includes investigators from Boston University, Kentucky BioProcessing (Owensboro, KY), Fenway Community Health Center (Boston, MA), Eastern Virginia Medical School (Norfolk, VA), Mucommune, Oak Crest Institute of Science (Monrovia, CA), the University of North Carolina at Chapel Hill, University of Louisiana at Lafayette, DuPont (Palo Alto, CA), and Mapp.
A human contraceptive antibody (HCA) formulated into a vaginal film will be tested for safety in Investigational New Drug (IND) enabling toxicology studies. After filing an IND application with the FDA, the HCA film will be tested for safety and surrogate efficacy in two Phase 1 clinical trials to be performed at Fenway Community Health Center and at Eastern Virginia Medical School.
"Reliable use of contraceptive methods significantly increases their efficacy, so end-user acceptability is key for effective contraception. Consequently, the consortium is focusing on vaginal films as an 'on demand' method for intermittent users, and intravaginal rings for longer-term protection,"
Plant and fungal manufacturing platforms for antibodies are being used by the consortium to address cost and scale challenges. "Nicotiana (tobacco) derived antibodies were recently evaluated in a phase 1 clinical trial of MB66," said Kevin J. Whaley. Whaley added, "We look forward to evaluating Trichoderma-manufactured antibodies that could meet demands of large, cost-sensitive markets."
Boston University School of Medicine is a leading academic medical center with an enrollment of more than 700 medical students and 950 students pursuing degrees in graduate medical sciences. BUSM faculty contribute to more than 950 active grants and contracts, with total anticipated awards valued at more than $693 million. For more information, please visit http://www.bumc.bu.edu/
