- CASGEVY is the first, and only, gene editing therapy approved for the treatment of transfusion-dependent beta thalassemia (TDT) and sickle cell disease (SCD) in Europe -

- Italy has the largest population of people living with TDT in Europe -

Vertex Pharmaceuticals (Nasdaq: VRTX) announced today a reimbursement agreement with the Italian Medicines Agency (AIFA) for eligible transfusion-dependent beta thalassemia (TDT) and severe sickle cell disease (SCD) patients to access the CRISPR/Cas9 gene-edited therapy, CASGEVY^® (exagamglogene autotemcel).

“Today is a turning point for eligible people in Italy living with transfusion-dependent beta thalassemia and sickle cell disease, two life-shortening diseases with limited treatment options,” said Ludovic Fenaux, Senior Vice President, Vertex International. “Italy has the largest TDT population in Europe, which underscores the importance of this agreement. We appreciate the collaboration with AIFA to recognize the value a one-time transformative treatment provides to patients, families and the health care system.”

In Italy, there are approximately 5,000 people 12 years and older living with TDT and around 2,300 with SCD. Italy joins a number of countries that have signed reimbursement agreements for CASGEVY including Austria, Bahrain, Denmark, England, the Kingdom of Saudi Arabia and the United Arab Emirates.

About Transfusion-Dependent Beta Thalassemia (TDT)

TDT is a serious, life-threatening genetic disease. TDT patients report health-related quality of life scores below the general population and significant health care resource utilization. TDT requires frequent blood transfusions and iron chelation therapy throughout a person’s life. Due to anemia, patients living with TDT may experience fatigue and shortness of breath, and infants may develop failure to thrive, jaundice and feeding problems. Complications of TDT can also include an enlarged spleen, liver and/or heart, misshapen bones and delayed puberty. TDT requires lifelong treatment and significant use of health care resources, and ultimately results in reduced life expectancy, decreased quality of life and reduced lifetime earnings and productivity. In Europe, the mean age of death for patients living with TDT is 50-55 years.

About Sickle Cell Disease (SCD)

SCD is a debilitating, progressive, life-shortening genetic disease. SCD patients report health-related quality of life scores well below the general population and significant health care resource utilization. SCD affects the red blood cells, which are essential for carrying oxygen to all organs and tissues of the body. SCD causes severe pain, organ damage and shortened life span due to misshapen or “sickled” red blood cells. The clinical hallmark of SCD is vaso-occlusive crises (VOCs), which are caused by blockages of blood vessels by sickled red blood cells and result in severe and debilitating pain that can happen anywhere in the body at any time. SCD requires lifelong treatment and significant use of health care resources, and ultimately results in reduced life expectancy, decreased quality of life and reduced lifetime earnings and productivity. In Europe, the mean age of death for patients living with SCD is around 40 years.

About CASGEVY^® (exagamglogene autotemcel)

CASGEVY^® is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or TDT, in which a patient’s own hematopoietic stem and progenitor cells are edited at the erythroid specific enhancer region of the BCL11A gene through a precise double-strand break. This edit results in the production of high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. CASGEVY has been shown to reduce or eliminate VOCs for patients with SCD and transfusion requirements for patients with TDT.

CASGEVY is approved for eligible SCD and TDT patients 12 years and older by multiple regulatory bodies around the world. In the European Union, CASGEVY is approved for patients 12 years of age and older with either severe SCD with recurrent VOCs or TDT, for whom hematopoietic stem cell (HSC) transplantation is appropriate and a human leukocyte antigen matched related HSC donor is not available.
