SATELLITE SYMPOSIUM
ARE HIGHER FACTOR LEVELS A RISING CONSIDERATION WHEN SELECTING A HEMOPHILIA TREATMENT? (SPONSORED BY NOVO NORDISK, INC. )
Chicago Ballroom VI

This program will discuss the clinical relevance of reaching high factor activity levels in patients with hemophilia. An increased risk of bleeding episodes exists with time spent at low factor activity levels, and the World Federation of Hemophilia recognizes the importance of high factor activity levels and maintaining hemostasis in patients with hemophilia. The pharmacokinetic and clinical characteristics of products used to treat patients with hemophilia will also be presented. Click Here to take the post survey.



NEW CLINICAL DATA FOR PROPHYLAXIS IN VON WILLEBRAND DISEASE AND HEMOPHILIA A (SPONSORED BY OCTAPHARMA AG)
Chicago Ballroom IX-X

Join Jill Johnsen, Robert Sidonio and Craig Kessler for this symposium putting prophylaxis under the spotlight and presenting new clinical data and ongoing investigations for its use in people with von Willebrand disease (VWD) and hemophilia A. The potential for prophylaxis to offer optimal bleed protection in people with VWD will be discussed, supported by new clinical data from a recently completed prospective trial of prophylaxis with a von Willebrand factor/coagulation factor VIII (VWF/FVIII) concentrate. Next generation sequencing (NGS) is a powerful tool whose use to characterize VWF mutations may improve VWD diagnosis and management. In people with severe hemophilia A, prophylaxis is widely accepted as the standard of care, and should be personalized to the patients needs. However, the lack of head-to-head studies of different FVIII products makes it challenging to make informed treatment decisions. Insights into the relative effects of different products can be obtained through indirect comparisons using validated statistical methodology. The results of such a comparison of personalized prophylaxis studies in hemophilia A will be presented and discussed. The differential binding capacity for rFVIII concentrates could have implications in platelet biology and new scientific data will be presented.

Genentech invites you to Help Crack the Case! in a fun-filled interactive mystery game showat this year's THSNA symposium. You'll hear from real patients and caregivers to find out just who's right for a subcutaneous prophylaxis option, and play along with our expert contestant, Dr. Michael Silvey. Throughout our game show, well explore considerations for identifying potential patients and learn more about the different patient types. You may be surprised at who these typical patients turn out to be! Plus, youll have an opportunity to have your questions answered in our live Q&A session. We look forward to seeing you there!


LONG-TERM MONITORING OF CLINICAL EFFICACY AND SAFETY PARAMETERS FOR INVESTIGATIONAL HEMOPHILIA GENE THERAPY (SPONSORED BY PFIZER)
Chicago Ballroom VI

This symposium will discuss the importance of patient monitoring both in the short- and long-term, exploring the variables that need to be considered in order to assess clinical efficacy and safety parameters of gene therapy. Presenters of this symposium will explore the practicalities of monitoring these parameters, focusing on coagulation assays and liver investigations, and review the questions that need to be addressed in the future in order to further our understanding of the mechanisms underlying this potential therapeutic approach. Gene therapy for the treatment of hemophilia is investigational. There are no gene therapies currently approved in the US for hemophilia.

Recognizing the history and reasoning for exploring gene therapy in lifelong conditions like hemophilia will be a focus of this conversation with the experts. During this dinner symposium, attendees will be part of expert discussions on topics relating to liver health in the context of liver-directed gene therapy, follow-up care and surveillance registries in patients with hemophilia, and practical logistics for establishing and maintaining successful gene therapy transfer clinic operations. The four leading experts will provide updates on these cutting-edge, scientific topics followed by an open panel discussion with attendees. We hope that you will join us.
