*  Haemophilia B - Wikipedia
Haemophilia B (or hemophilia B) is a blood clotting disorder caused by a mutation of the factor IX gene, leading to a deficiency of factor IX. It is the second-most common form of haemophilia, rarer than haemophilia A. Haemophilia B was first recognized as a different kind of haemophilia in 1952. It is sometimes called Christmas disease, named after Stephen Christmas, the first patient described with this disease. In addition, the first report of its identification was published in the Christmas edition of the British Medical Journal. The presentation of hemophilia B is consistent with easy bruising, urinary tract bleed and nosebleeds. Additionally, the affected individual may experience bleeding into their joints. The factor IX gene is located on the X chromosome (Xq27.1-q27.2). It is an X-linked recessive trait, which explains why, as in haemophilia A, usually only males are affected. In 1990, George Brownlee and Merlin Crossley showed that two sets of genetic mutations ...

In severe cases of hemophilia, heavy bleeding occurs after minor trauma or even in the absence of injury. Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms may not become apparent until abnormal bleeding occurs following surgery or a serious injury. People with an unusual form of hemophilia B, known as hemophilia B Leyden, experience episodes of excessive bleeding in childhood but have few bleeding problems after puberty.

Investigators report no evidence of toxicity in the four hemophilia B patients enrolled to date in a gene therapy trial using a vector under development at St. Jude Children's Research Hospital and UCL (University College London) to correct the inherited bleeding disorder.. This trial was designed primarily as a safety test, with low and intermediate doses of the vector expected to produce little detectable Factor IX. The Factor IX protein helps the blood form clots. Individual with hemophilia B lack adequate levels of this clotting factor. The first participant in the open-label Phase I/II trial had an unexpectedly high level of Factor IX expression after receiving the lowest dose of the vector being tested in this study. Levels of the Factor IX protein rose from less than 1 percent to 2 percent of normal after the experimental vector was infused into the patient.. The patient's Factor IX production remains elevated more than nine months later. Since the infusion the ...

Hemophilia B is a genetic X-linked bleeding disorder caused by a deficiency in blood-clotting Factor IX (FIX) activity. FIX is synthesized in the liver and circulates in the blood as a proenzyme. Current treatment for hemophilia B is based on replacement of the deficient FIX with IV injections of recombinant FIX protein prophylactically or as needed to treat bleeding episodes. This clinical program will test a gene transfer approach involving the use of a gene delivery vector carrying a FIX gene. This first-in-humans study is intended to evaluate the safety, kinetics, and if possible, the dose of AskBio009 required to achieve stable plasma FIX activity between 10% and 40% of normal activity ...

*  Gene therapy found effective in hemophilia B » Haemophilia Foundation of New Zealand Inc.
In 10 patients with severe haemophilia B, the infusion of a single dose of gene therapy with an AAV8 vector resulted in long-term therapeutic factor IX expression associated with clinical improvement. With a follow-up period of up to 3 years, no late toxic effects from the therapy were reported.. A recently published study updates an earlier one from 2011, in which six volunteers were successfully treated with various doses of the treatment that uses a virus to insert genetic material into the liver. The four additional patients received the highest dose. Dr. Andrew Davidoff of St. Jude Children's Research Hospital in Memphis, Tennessee and his colleagues found that the higher the dose of the engineered virus, the more factor IX the body produced. The researchers used an adeno-associated virus or AAV, which infects the liver without causing apparent illness.. The therapy seemed to have no serious side effects and is designed to eliminate the need to give patients injections of factor IX. The ...

*  Paper: Clinical Outcomes of 14-Day Prophylaxis with rFIXFc: Longitudinal Analysis of the B-LONG and B-YOND Study
Introduction Despite the advent of extended half-life factor IX (FIX) products with the potential for 14 days or longer prophylactic dosing in patients with severe hemophilia B, long-term data on the use of ≥14-day dosing are lacking for prolonged periods of observation. A post hoc analysis of the B-LONG Phase 3 trial showed that ~50% of subjects in the individualized interval prophylaxis treatment arm (Arm 2, n=29) used extended dosing intervals (≥14 days) and had low annualized bleed rates (ABRs) that were similar to ABRs in subjects on other dosing intervals in Arm 2.1. The purpose of this analysis was to evaluate whether sustained ≥14-day dosing with recombinant FIX Fc fusion protein (rFIXFc) can provide safe and effective protection from bleeding in selected patients with severe hemophilia B over time in a near real-world setting. Methods B-LONG (NCT01027364) enrolled 123 adults and adolescents ≥12 years of age into 1 of 4 treatment arms: weekly prophylaxis (50 IU/kg ...

*  Repositorio da Producao Cientifica e Intelectual da Unicamp: RNA-based gene therapy for haemophilia B
Haemophilia B, a deficiency in clotting factor IX (FIX), occurs in about I in 25.000 males. Of these patients, approximately 40% are characterized as having 'severe' haemophilia (FIX below 1% of normal). Although the use of plasma-derived or rFIX has extended the lifespan of these patients, they remain afflicted by a variety of sequelae of the disease. Interestingly, a relatively small increase in the levels of FIX results in a dramatic increase in the quality of life, requiring rFIX substitution only prior to dental and surgical procedures. This latter trait of the disease suggests that gene therapy only needs to achieve modest expression and makes this disease a prime candidate for proof-of-concept of gene therapy. Current protocols for gene therapy entail the risk of malignant transformation. In addition the viral vectors may cause substantial pathology. Hence, the field requires the development of inherently safe gene therapy. Recently, developed protocols have been developed to transduce ...

*  Paper: Spk-9001: Adeno-Associated Virus Mediated Gene Transfer for Hemophilia B Achieves Sustained Factor IX with Minimal...
Background: Data from earlier hemophilia B (HB) AAV-mediated liver gene transfer trials demonstrated a dose-dependent, capsid-specific immune response that may result in clearance of transduced hepatocytes and loss of transgene expression (Manno et al. 2006, Mingozzi et al. 2007). This has not posed major safety concerns, but may limit efficacy. Prior work incorporated the use of steroids to abort this immune response and maintain factor IX (FIX) expression (Nathwani et al 2014). The percent of transgene expression lost increased with number of elapsed days from transaminase elevation to steroid initiation. Once vector responsiveness to steroids is established, the need for steroids is not a limitation in and of itself but highlights the requirement to reliably and expeditiously recognize an immune response and initiate steroids. Here we present our immunomonitoring data following infusion of SPK-9001, an AAV vector designed to achieve therapeutic FIX:C at a low vector dose to minimize ...

*  New Method To Detect Antibodies Linked To Inhibitor Development - CIBD | Center For Inherited Blood Disorders
In an article release by the CDC (Center for Disease Control and Prevention), research reports key findings related to the formation of inhibitors (antibodies) in patients who have hemophilia. The study shows that hemophilia A and hemophilia B patients who develop inhibitors are likely to have a specific type of antibody called immunoglobulin G subclass 4, or IgG4. In the event that traditional inhibitor tests do not provide clear results, testing for these antibodies instead may help clarify whether an inhibitor is present.. Inhibitors are antibodies (protein) that prevents or stops infused factor from working. For those with bleeding disorders like hemophilia A and hemophilia B, inhibitors often develop because the body's immune system identifies the clotting factor as foreign. A blood test called Nijmegen-Bethesda Assay (NBA) is used to diagnose inhibitors.. For some cases, NBA can produce an unclear result as to whether ...
