The Sound of What's Next in Hemophilia

You spoke, we listened. Hear the voices that are speaking out
for change in the hemophilia community.

Get to know BioMarin Hemophilia

We’re here to amplify your voice

At BioMarin Hemophilia we aspire to lift the voice of the hemophilia community the same way you inspire us to keep researching and moving toward the exceptional with our science. Every day we make it our purpose to put you first. From our clinical research and development to supporting your local advocacy group—we’re focused on doing everything we can to hear and help the hemophilia community thrive.

What you can expect from us

Our values and purpose—they're not just words. Sure, they're on posters in our offices, right next to pictures of our kids and our dogs, but that's because we are driven by them. And we know we must live them, day in, day out, to effect real change.

Our purpose

We are inspired by a hemophilia community with huge aspirations and driven to deliver on the ingenuity of gene therapy clinical research and exploration.

Our behaviors

We celebrate the people we serve
We are better together
In the face of obstacles, we see opportunity
We aim higher

BioMarin and hemophilia timeline

  1. Hemophilia—
    The royal disease


    Hemophilia is sometimes referred to as “the royal disease,” because it affected the royal families of England, Germany, Russia, and Spain in the 19th and 20th centuries.

  2. Mendel’s theory
    of inheritance


    Born in the Old Austrian empire, Gregor Mendel was a Czech monk who worked out the basic laws of inheritance before the term gene had been invented. Mendel performed thousands of experiments with garden peas. He explained his results by describing two laws of inheritance that introduced the idea of dominant and recessive traits.

  3. DNA isolated


    Frederick Miescher isolated DNA from cells for the first time and called it nuclein.

  4. Whole-blood transfusion
    in hospital


    In 1940, Edwin Cohn, a professor at Harvard Medical School, developed the process of breaking down plasma into components and products. Albumin, a protein with powerful osmotic properties, plus gamma globulin and fibrinogen were isolated and became available for clinical use.

    In 1941, Isodor Ravdin, a Philadelphia surgeon, effectively treated victims of the Pearl Harbor attack with Cohn's albumin for shock.

  5. DNA double helix


    James D. Watson and Francis H. Crick described the double helix structure of DNA. They received the Nobel Prize for their work in 1962.

  6. At-home replacement therapy
    available, with plasma-derived
    factor concentrates


    The modern management of hemophilia really began in the 1970s with the production of coagulation factors. This innovation greatly improved the quality of life and longevity of people with hemophilia, permitting the widespread adoption of at-home replacement therapy.

  7. Dr. Barrie Carter begins
    work on AAV-mediated gene transfer biotechnology at the National Institutes of Health


  8. Dr. Gordon Vehar begins
    work on factor VIII


  9. Genes for factor VIII
    and factor IX are cloned


    The successful cloning of the factor VIII gene in 1984 was a major breakthrough, allowing production of recombinant human factor VIII. Cloning of factor IX was first reported in 1982.

  10. The Centers for Disease
    Control (CDC) reports first AIDS
    case in hemophilia


    In 1982, products derived from contaminated blood led to the first CDC-reported cases of patients with hemophilia A developing pneumonia and other infections that met the case definition of AIDS.

  11. Dr. Barrie Carter publishes
    a paper describing the use
    of AAV as a vector


    In October 1984, Dr. Barrie Carter published A Human Parvovirus, Adeno-Associated Virus, as a Eucaryotic Vector: Transient Expression and Encapsidation of the Procaryotic Gene for Chloramphenicol Acetyltransferase, an article first describing the use of adeno-associated virus as a vector.

  12. Dr. Gordon Vehar publishes
    a paper reporting successful
    factor VIII cloning


    Expression of Active Human Factor VIII From Recombinant DNA Clones by Dr. Gordon Vehar and his colleagues reported on the successful cloning of factor VIII, a breakthrough advancement.

  13. Dr. Wing Yen Wong
    begins hematology


  14. First gene therapy
    trial in humans


    A 4-year-old girl suffering from adenosine deaminase (ADA), a condition in which people cannot resist common infections, became the first person to receive a non-AAV gene therapy treatment.

  15. Recombinant clotting
    factors approved

    FVIII 1992
    FIX 1997
    FVIIa 1999

    Throughout the 1990s, synthetic factor products were manufactured using recombinant technologies. In 1992, the first recombinant factor VIII product was approved by the FDA. In 1997, the first recombinant factor IX product was granted FDA approval. In 1996, rFVIIa was approved in the European Union and in 1999 in the United States for use as a bypassing agent in patients with hemophilia A or B (factor VIII or factor IX deficiency) and an antibody inhibitor.

  16. BioMarin incorporates


    Founded in March 1997, with a $1.5 million investment from Glyko Biomedical Ltd., BioMarin was open for business.

  17. Lessons learned regarding risks
    related to potential for severe
    immune response in early gene
    therapy trial with non-AAV vector


    Lessons were learned from serious problems that highlighted the potential toxicity of other viral vectors in earlier trials of gene therapy, leading to the research into new and different technologies.

  18. Prophylaxis is recommended as
    standard of care


  19. Human Genome Project


    The Human Genome Project (HGP) was an international research effort to sequence and map all of the genes—together known as the genome—of members of our species, homo sapiens. Completed in April 2003, the HGP gave us the ability, for the first time, to read nature's complete genetic blueprint for building a human being.

  20. First gene therapy trial in
    hemophilia B using
    AAV vector technology


    In a 2005 clinical gene transfer trial, it was found that the human liver can be transduced by recombinant adeno-associated viral (rAAV) vector after in vivo delivery of the vector.

  21. BioMarin therapies for
    rare diseases approved

    Mucopolysaccharidosis I 2003
    Mucopolysaccharidosis VI 2005
    Phenylketonuria 2007

    Over the years, BioMarin has extended its commitment to those communities with rare diseases.

  22. Dr. Gordon Vehar joins BioMarin


  23. Dr. Barrie Carter joins BioMarin


  24. Extended half-life
    factors approved


  25. BioMarin therapies for
    rare diseases approved

    Mucopolysaccharidosis IVA 2014
    Neuronal ceroid lipofuscinosis type 2 2017

  26. BioMarin doses the first patient in an investigational gene therapy trial in hemophilia A to research safety and efficacy
    (BMN 270-201)


    In 2015 BioMarin dosed its first patient in the BMN 270 clinical trial - evaluating the safety, dosing, and efficacy of a gene therapy for adults with hemophilia A.
