MHRA Grants Marketing Authorization for GBT’s Oxbryta® (voxelotor) for Use in Great Britain for the Treatment of Hemolytic Anemia in Patients with Sickle Cell Disease Age 12 Years and Older
Voxelotor is the first medicine approved in Great Britain to directly inhibit sickle hemoglobin (HbS) polymerization, the underlying molecular cause of sickle cell disease
SOUTH SAN FRANCISCO, Calif., July 26, 2022 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ: GBT) today announced that the Medicines and Healthcare products Regulatory Agency (MHRA) has granted Great Britain marketing authorization for Oxbryta® (voxelotor) for the treatment of hemolytic anemia due to sickle cell disease (SCD) in adult and pediatric patients 12 years of age and older as monotherapy or in combination with hydroxycarbamide (hydroxyurea). Voxelotor, an oral treatment taken once daily, is the first medicine authorized in Great Britain that directly inhibits sickle hemoglobin (HbS) polymerization, the molecular basis of sickling and destruction of red blood cells in SCD.
“We welcome the MHRA’s marketing authorization of voxelotor as a new treatment option for many people in Great Britain living with sickle cell disease, a devastating life-long condition which for far too long has seen little therapeutic innovation,” said Beatriz F. Pujol, Ph.D., vice president, head of medical affairs EU & GCC at GBT. “Following this marketing authorization by the MHRA, we look forward to working with the National Institute of Health and Care Excellence (NICE) and the Scottish Medicines Consortium (SMC) with the goal of helping to facilitate rapid access to voxelotor for people living with sickle cell disease who may benefit from this important treatment.”
SCD affects approximately 15,000 people in the UK.1 People living with SCD experience progressive, serious complications and morbidities, including organ damage, which lead to decreased quality of life and early mortality.2 Furthermore, economic disadvantages and health inequalities experienced by many patients with SCD can have negative societal impacts in areas such as access to healthcare, education and employment.3-9
In 2021, voxelotor was the first SCD treatment to receive a Promising Innovative Medicine (PIM) designation from the MHRA, which subsequently granted the medicine a positive scientific opinion under the Early Access to Medicines Scheme (EAMS). This enabled healthcare professionals to treat selected patients with voxelotor prior to market authorization based on clinical factors to address a clear unmet medical need.
The marketing authorization by the MHRA, which follows the European Commission (EC) authorization earlier this year, is based on results demonstrating clinically meaningful and statistically significant improvements in hemoglobin (Hb) levels, accompanied by a reduction of hemolysis markers, for patients treated with voxelotor. Data from the Phase 3 HOPE (Hemoglobin Oxygen Affinity Modulation to Inhibit HbS Polymerization) Study of 274 patients 12 years of age and older with SCD showed that, after 24 weeks of treatment, 51.1% of patients receiving voxelotor achieved a greater than 1 g/dL increase in Hb compared with 6.5% receiving placebo (p<0.001), with significant improvements in markers of hemolysis in indirect bilirubin and reticulocyte percentage.10 In the HOPE Study, the most common adverse reactions occurring in ≥10% of patients treated with Oxbryta with a difference of >3% compared to placebo were headache (26% vs. 22%), diarrhea (20% vs. 10%), abdominal pain (19% vs. 13%), nausea (17% vs. 10%), fatigue (14% vs. 10%), rash (14% vs. 10%) and pyrexia (12% vs. 7%).10 Results from the HOPE Study were published in June 2019 in The New England Journal of Medicine and the analysis of the complete data from the HOPE Study was published in The Lancet Haematology in April 2021.
The EC decision, which was granted in February 2022, provides marketing authorization in all EU member states, as well as the additional member states of the European Economic Area, including Iceland, Liechtenstein and Norway. The MHRA grants marketing authorization in Great Britain.
About Sickle Cell Disease
It is estimated that more than 100,000 people in the United States,11 52,000 people in Europe,12 up to 100,000 people in Brazil,13 and millions of people throughout the world have sickle cell disease (SCD).11 SCD occurs particularly among those whose ancestors are from sub-Saharan Africa, though it also occurs in people of Hispanic, South Asian, Southern European and Middle Eastern ancestry.11 SCD is a lifelong inherited blood disorder that impacts hemoglobin, a protein carried by red blood cells that delivers oxygen to tissues and organs throughout the body.14 Due to a genetic mutation, individuals with SCD form abnormal hemoglobin known as sickle hemoglobin. When sickle hemoglobin becomes deoxygenated, it polymerizes to form rods, which deforms the red blood cells into sickled – crescent-shaped, rigid – cells.2,14,15 The recurrent sickling process causes destruction of the red blood cells, hemolysis and anemia (low hemoglobin due to red blood cell destruction), which drives vascular inflammation contributing to blockages in capillaries and small blood vessels (vaso-occlusion) that impede the flow of blood and oxygen delivery throughout the body. Episodes of painful vascular occlusions are commonly referred to as vaso-occlusive crises (VOCs). The diminished oxygen delivery to tissues and organs can lead to life-threatening complications, including stroke and irreversible organ damage.2,15-18 Complications of SCD begin in early childhood and can include neurocognitive impairment, acute chest syndrome, and silent and overt stroke, among other serious issues.19 Early intervention and treatment of SCD have shown potential to modify the course of this disease, reduce symptoms and events, prevent long-term organ damage, and extend life expectancy.2
About Oxbryta® (voxelotor)
Voxelotor is an oral, once-daily therapy for patients with sickle cell disease (SCD). Voxelotor works by increasing hemoglobin’s affinity for oxygen. Since oxygenated sickle hemoglobin does not polymerize, voxelotor inhibits sickle hemoglobin polymerization and the resultant sickling and destruction of red blood cells leading to hemolysis and anemia, which are primary pathologies faced by every single person living with SCD. Through addressing hemolysis and anemia and improving oxygen delivery throughout the body, GBT believes that voxelotor has the potential to modify the course of SCD.
In November 2019, the U.S. Food and Drug Administration (FDA) granted accelerated approval for voxelotor tablets, under the brand name Oxbryta®, for the treatment of SCD in adults and children 12 years of age and older, and in December 2021, the FDA expanded the approved use of Oxbryta for the treatment of SCD in patients 4 years of age and older in the United States.9 As a condition of accelerated approval for patients ages 4 and older in the United States, GBT is studying Oxbryta in the HOPE-KIDS 2 Study, a post-approval confirmatory study using transcranial Doppler (TCD) flow velocity to assess the ability of the therapy to decrease stroke risk in children 2 to 14 years of age.
In recognition of the critical need for new SCD treatments, the FDA granted Oxbryta Breakthrough Therapy, Fast Track, Orphan Drug, and Rare Pediatric Disease designations for the treatment of patients with SCD. Additionally, Oxbryta received the prestigious 2021 Prix Galien USA award for “Best Biotechnology Product” from The Galien Foundation.
Oxbryta has been granted Priority Medicines (PRIME) designation from the European Medicines Agency (EMA), Oxbryta was designated by the European Commission (EC) as an orphan medicinal product for the treatment of patients with SCD, and Oxbryta was granted Promising Innovative Medicine (PIM) designation in the United Kingdom from the Medicines and Healthcare products Regulatory Agency (MHRA). In February 2022, the European Commission (EC) granted Marketing Authorization for Oxbryta for the treatment of hemolytic anemia due to SCD in adult and pediatric patients 12 years of age and older as monotherapy or in combination with hydroxycarbamide (hydroxyurea). In addition, Oxbryta has been approved in the United Arab Emirates (UAE) and Oman for the treatment of SCD in adults and children 12 years of age and older.
