"We hope that many people will participate in the My Life, Our Future program to learn more about their genetic profile and to contribute knowledge that may help future generations," said Barbara Konkle, M.D., Director of Clinical and Translational Research at PSBC. "As a physician, I believe this initiative will provide Hemophilia Treatment Centers with a critical tool to individualize care for people with hemophilia and their families today."National Database and Research Repository Will Be Enhanced Beyond receiving their individual genotyping results, participants can help accelerate scientific research in hemophilia by contributing data and samples to a secure national database and research repository. In the future, scientists can apply through ATHN for access to the data or samples to conduct research. The confidentiality of participants who contribute their data and samples will be protected. Patient identifying information will not be entered into the database and the repository, nor given to researchers. "With an enhanced database, researchers will be able to investigate the connection between the genetic cause of hemophilia and clinical outcomes," said Diane Aschman, President and Chief Executive Officer of ATHN. "Future researchers will be better equipped to improve the care of hemophilia and identify new treatment approaches." A Partner Dedicated to Serving the Hemophilia Community Biogen Idec Hemophilia, a business unit of Biogen Idec with expertise in hemophilia and genetic medicine, will provide financial backing for the initiative, as well as scientific advice and project management support. "Our goal is to empower people with hemophilia to live the lives they choose," said Glenn Pierce, M.D., Ph.D., Chief Medical Officer of Biogen Idec Hemophilia. "This initiative fits perfectly with our mission because it offers knowledge to patients, their families, healthcare providers and researchers that can improve care and advance science." The company is supporting My Life, Our Future as a service to the community, and will not have special access to the data or samples generated by the initiative. About My Life, Our Future: Genotyping for Progress in Hemophilia My Life, Our Futureis a partnership of the National Hemophilia Foundation (NHF), the American Thrombosis and Hemostasis Network (ATHN), Puget Sound Blood Center (PSBC), and Biogen Idec Hemophilia. The program will offer free or very low cost genotyping to people affected by hemophilia in the U.S., and will become available through participating Hemophilia Treatment Centers (HTCs) in 2013. Initially, the service will be offered to people with hemophilia A and B. Over time, it will be expanded to include potential carriers in their families.
