FIRST EVER HEMOPHILIA PATIENT TO RECEIVE GENE THERAPY SINCE FDA APPROVAL

FOR IMMEDIATE RELEASE

JUNE 20, 2023

GREEN BAY, WI- Wisconsin resident is the first ever hemophilia B patient to receive gene therapy since FDA approval.

“I feel honored to be the first person to participate in this therapy outside of the clinical trials. I am very excited that I am going to be helping to prove that this is a treatment option for individuals with hemophilia B.”-Mason Buxton

HEMGENIX (etranacogene dezaparvovec), manufactured by uniQure Inc. and distributed by CSL Behring LLC, was FDA approved November of 2022 and is for the treatment of adults with Hemophilia B (Factor IX Deficiency) who currently use Factor IX preventative therapy, or have current or historical life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.

Hemophilia B is a genetic bleeding disorder resulting from missing or insufficient levels of blood clotting Factor IX, a protein needed to produce blood clots to stop bleeding. Symptoms can include prolonged or heavy bleeding after an injury, surgery, or dental procedure; in severe cases, bleeding episodes can occur spontaneously without a clear cause. Prolonged bleeding episodes can lead to serious complications, such as bleeding into joints, muscles or internal organs, including the brain.

Although HEMGENIX is not a cure for Hemophilia B patients, the medical advancement may reduce, if not, eliminate weekly preventative factor replacement and bleeds.

“HEMGENIX is an important addition to the current treatment paradigm and a long-awaited advancement for the hemophilia B community,” said Matthew Ryan, MD, Adult Hematologist and Medical Director at Hemophilia Outreach Center, Green Bay, WI. “This exciting treatment offers patients a chance to live a life without frequent bleeds or the burden of regular infusions. The availability of this new one-time treatment also sparks additional conversations in the community when it comes to treatment options and goals, which is extremely important when managing a life-long condition, as an individual’s needs can change for a variety of reasons.”

“I’m just excited that patients have this new opportunity that will lead to such a better quality of life versus their current prophylaxis treatment! To live a life free from recurrent prophylaxis, not having that anxiety over if they are going to have a bleed or if they have factor with them, not worrying about damage to their joints from breakthrough bleeds….it will be very lifechanging for them.”- Andrea Miller, APNP, Hemophilia Outreach Center.
