Blood-clotting protein modified for people with hard-to-treat hemophilia
Date:5/19/2008

ntibodies, Smith said.

There is no cure for Hemophilia A, and it primarily affects males. About one of every 7,000 males born in the United States has this condition. A person with hemophilia bleeds longer than a person without hemophilia.

Stephanie Planque, who is lead author and is working towards her Ph.D. degree, helped conceive the chemical inactivation principle behind the study. The modified FVIII analog was produced by pathology faculty Hiroaki Taguchi, Ph.D., and Yasuhiro Nishiyama, Ph.D., using newly developed synthesis methods. Miguel Escobar, M.D., of the department of pediatrics and internal medicine at the UT Medical School at Houston and the Gulf States Hemophilia and Thrombophilia Center, led the clinical aspects of the work, and Kathleen Pratt, Ph.D., at the Puget Sound Blood Center and Division of Hematology, University of Washington, Seattle, contributed a genetically-produced protein that helped the study reach its conclusions.

According to Paul, the next step involves clinical trials. E-FVIII is a first generation reagent. Future genetic and chemical manipulations may help develop improved E-FVIII analogs, Paul wrote in the paper.
