  • Assessing Physician and Hemophilia A Patient Reasons and Expectations for Switching Treatment to Kovaltry: A Nested Study Within an Existing Registry

    open to eligible people ages 2 years and up

    This US study aims to assess hemophilia A patient characteristics and reasons for switching from both patient/caregiver and physician perspectives. For this purpose, this research study will include hemophilia A patients who have switched from an existing therapy to Kovaltry. In doing so, real world evidence will be obtained from both patient and physician perspectives offering key insights for effective therapeutic management of patients with hemophilia A and to more fully understand what drives patient switching from a patient perspective and a physician perspective.

  • ATHN 2: Factor Switching Study

    open to all eligible people

    This is a longitudinal, observational study of patients with Hemophilia A or B who are planning to switch to a newly approved coagulation factor replacement product, or who have recently switched factor products. The study will follow each patient for up to 1 year. Patients will be recruited at Hemophilia Treatment Centers (HTC) which are ATHN-affiliates. The primary outcome being studied is the development of inhibitor (i.e., antibodies to factor) at 1 year or 50 exposure days, whichever comes first. The study will be conducted at approximately 30 HTCs, with a planned enrollment of 600 patients.The entire study duration is projected to be approximately 6 years. In addition, optional substudies will be included for some products, as "Product-Specific Modules". These will be questionnaires to collect data for subjects receiving selected Factor products. For example, subjects receiving Kovaltry will be approached to participate in the 'Kovaltry Product-Specific Module'; subjects receiving Adynovate will be approached to participate in the 'Adynovate Product-Specific Module'. Questions will be related to product use, perceptions of product use, and other post-marketing consumer data.

  • HOPE-B: Trial of AMT-061 in Severe or Moderately Severe Hemophilia B Patients

    open to eligible males ages 18 years and up

    This is an open-label, single-dose, multi-center, multinational trial to demonstrate the efficacy of AMT-061 and to further describe its safety profile. The study drug is identified as AAV5-hFIXco-Padua (AMT- 061). AMT-061 is a recombinant adeno-associated viral vector of serotype 5 (AAV5) containing the Padua variant of a codon-optimized human FIX complementary deoxyribonucleic acid (cDNA) under the control of a liver-specific promoter. The pharmaceutical form of AMT-061 is a solution for intravenous infusion administered at a dose of 2 x 1013 gc/kg.

  • Single-Arm Study To Evaluate The Efficacy and Safety of Valoctocogene Roxaparvovec in Hemophilia A Patients

    open to eligible males ages 18 years and up

    This clinical trial is being conducted to learn more about a potential treatment (valoctocogene roxaparvovec) for people with severe hemophilia A. This research study will test and confirm the safety and effectiveness of the 6E13 vg/kg dose of the study drug (valoctocogene roxaparvovec) that contains the correct gene to make Factor VIII so that the body can make its own Factor VIII that functions properly. Only one dose of valoctocogene roxaparvovec is being given in this study, and this dose has been previously studied in another clinical trial in patients with hemophilia A. This is a phase 3 study which is meant to show that the study drug is safe and works to help treat hemophilia A. The study will see if liver cells are able to make Factor VIII that functions properly after receiving this study drug. The study will also examine the effects that the study drug has on how much Factor VIII concentrates patients have to inject into their veins and on their bleeding episodes after the study drug has been administered. Finally, the study will see if and how the body responds to the study drug - for example, whether liver cells become inflamed or whether the body makes antibodies (something the immune system makes to protect itself against things like bacteria and viruses) against the vector or the new Factor VIII gene.

  • Dose Confirmation Trial of AAV5-hFIXco-Padua

    Sorry, in progress, not accepting new patients

    This is an open-label, single-dose, single-arm, multi-center trial, with a screening, a treatment + post-treatment follow-up phase, and a long-term follow-up phase. The IMP AMT-061 is a recombinant adeno-associated viral vector of serotype 5 (AAV5) containing the Padua variant of a codon-optimized human FIX complementary deoxyribonucleic acid (cDNA) under the control of a liver-specific promoter. The IMP is identified as AAV5-hFIXco-Padua (AMT- 061). The pharmaceutical form of AMT-061 is a solution for intravenous infusion. The administered dose of AMT-061 will be 2 x 1013 gc/kg.

  • Effects of Emicizumab vs. Factor VIII Prophylaxis on Joint and Bone Health in Severe Hemophilia A

    Sorry, not currently recruiting here

    The investigators propose to study longitudinal joint and bone density changes in patients with severe Hemophilia A. Per current standard of care, most patients are on prophylactic FVIII replacement therapy intravenously several times weekly with a goal of keeping the trough >1% FVIII. Recent phase 3 data suggest superior bleed protection with emicizumab prophylaxis every 1-2 weeks. It is the purpose of this study to longitudinally assess joint health and bone density over 3 years and to compare the effect of routine factor VIII prophylaxis with emicizumab prophylaxis.

  • Joint Health Study

    Sorry, in progress, not accepting new patients

    This is a prospective, non-randomized, controlled study to examine whether or not having a higher trough during prophylactic treatment with clotting factor offers better joint protection than the standard trough of 1% Factor IX (FIX or Factor 9). This study will test the hypothesis that an extended half-life (EHL) FIX product with an intended trough of >10% could offer better protection than previous treatment concentrates. This study also examines whether or not joint damage could be diagnosed earlier using ultrasound images.

  • Open-Label Single Ascending Dose of Adeno-associated Virus Serotype 8 Factor IX Gene Therapy in Adults With Hemophilia B

    Sorry, in progress, not accepting new patients

    The purpose of this study is to evaluate the safety of single ascending IV doses of a Factor IX (FIX) Gene Therapy in up to 16 Adults with Hemophilia B.

  • Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care

    Sorry, not currently recruiting here

    Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
