Global Blood Therapeutics, Inc. (GBT) announced that the European Medicines Agency (EMA) has completed the validation of GBT’s Marketing Authorization Application (MAA) for Oxbryta (voxelotor) tablets and started its standard review process.
A first-in-class oral, once-daily therapy, Oxbryta directly inhibits haemoglobin polymerization, the root cause of the sickling and destruction of red blood cells in SCD. The sickling process causes hemolytic anaemia (low haemoglobin due to red blood cell destruction) and blockages in capillaries and small blood vessels, which impede the flow of blood and oxygen throughout the body. The diminished oxygen delivery to tissues and organs can lead to life-threatening complications, including stroke and irreversible organ damage.
“Sickle cell disease has a devastating impact on the lives of patients and their families, including serious and life-threatening complications that can lead to organ damage and early death,” said Ted W. Love, M.D., president and chief executive officer of GBT. “Despite this overwhelming need, there are currently no approved therapies in Europe that have the potential to modify the course of the disease. We look forward to working with the EMA to meet our goal of bringing the first treatment for hemolytic anaemia in sickle cell disease to European patients as soon as possible.”
The marketing authorisation application is based on data from the Phase III HOPE study and the Phase II HOPE-KIDS 1 study, both of which enrolled patients at clinical sites in Europe. The HOPE study achieved its primary endpoint.
The analysis of the complete data from the HOPE study further demonstrated that Oxbryta, at a daily dose of 1,500mg, resulted in durable improvements in haemoglobin levels and markers of haemolysis over 72 weeks of treatment.
Oxbryta has already been approved in the US for the treatment of SCD in adults and children 12 years of age and older.
