Hemophilia clinical trials at UCSF
9 in progress, 4 open to eligible people

  • A Study to Evaluate the Efficacy and Safety of Factor IX Gene Therapy With PF-06838435 in Adult Males With Moderately Severe to Severe Hemophilia B

    open to eligible males ages 18-65

    This study will evaluate the efficacy and safety of PF-06838435 (a gene therapy drug) in adult male participants with moderately severe to severe hemophilia B (participants that have a Factor IX circulating activity of 2% or less). The gene therapy is designed to introduce genetic material into cells to compensate for missing or non-functioning Factor IX. Eligible study participants will have completed a minimum 6 months of routine Factor IX prophylaxis therapy during the lead in study (C0371004). Participants will be dosed once (intravenously) and will be evaluated over the course of 6 years. The main objectives of the study are to compare the annualized bleeding rate [ABR] of the gene therapy to routine prophylaxis from the lead-in study and to evaluate the impact that it may have on participant's Factor IX circulating activity [FIX:C].

  • 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.

  • Lead-in Study to Collect Prospective Efficacy and Safety Data of Current FVIII Prophylaxis Replacement Therapy in Adult Hemophilia A Participants

    open to eligible males ages 18 years and up

    The aim of this prospective, observational study is to establish a dataset on the frequency of bleeding events, as well as other characteristics of bleeding events and FVIII infusions, in patients with clinically severe hemophilia A receiving prophylactic FVIII replacement therapy as standard of care. The data collected from this study may assist in providing baseline information for comparison to the Spark's investigational hemophilia A gene therapy in future Phase 3 studies.

  • Six Month lead-in Study to Evaluate Prospective Efficacy and Safety Data of Current FIX Prophylaxis Replacement Therapy in Adult Hemophilia B Subjects (FIX:C≤2%) or Current FVIII Prophylaxis Replacement Therapy in Adult Hemophilia A Subjects (FIX:C≤1%)

    open to eligible males ages 18-64

    To establish a minimum of 6 months of prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish a minimum of 6 months of prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to SB-525 capsid (AAV6), prior to the Phase 3 gene therapy study. The enrollment for hemophilia B participants is completed. At this time participants are only being enrolled for hemophilia A cohort.

  • ATHN 7: Hemophilia Natural History Study

    Sorry, not currently recruiting here

    This is a real-world study of the safety of the treatments used for people with hemophilia. The study will follow people with hemophilia A or B from across the country for about 4 years as they receive treatment. The hemophilia treatment center (HTC) physician and participant will decide on the FDA-approved treatment to be used which may include non-factor products, bypassing agents, or clotting factor replacement products. The goal of this research is to study the use of hemophilia treatment products and their outcomes.

  • ATHN 8: PUPs Matter Study

    Sorry, not currently recruiting here

    This is a multi-center cohort study of approximately 250 previously untreated patients (PUPs) with congenital moderate to severe hemophilia A or B in a network of up to 50 US Hemophilia Treatment Centers (HTCs). Participants will be followed as they receive their first 50 exposure days (ED) to clotting factor replacement product, both prospectively and retrospectively. The data collected on evolving treatment practices will define the incidence and risk factors for inhibitor development during the high risk period of first 50 ED and improve the outcomes of this vulnerable population.

  • Dose-Ranging Study of Recombinant AAV2/6 Human Factor 8 Gene Therapy SB-525 in Subjects With Severe Hemophilia A

    Sorry, in progress, not accepting new patients

    The purpose of the study is to evaluate the safety, tolerability and time-course profile of FVIII activity levels with adaptive doses of SB-525.

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

    Sorry, in progress, not accepting new patients

    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.
