Advicenne announced that the Medicines & Healthcare products Regulatory Agency (MHRA) has granted marketing authorisation for Sibnayal™ (ADV7103) in the UK, for the treatment of distal renal tubular acidosis (dRTA). With this authorization, and following the recent approval by the European Commission to market Sibnayal™ for the treatment of dRTA in the European Union, Advicenne is now able to bring to market in the EU and the UK the first and only label-approved drug for the treatment of dRTA in adults, adolescents and children aged one year and older. Advicenne now has the opportunity to make a significant difference to patients suffering from dRTA, classified as an orphan condition in Europe. Distal renal tubular acidosis (dRTA) is an orphan disease characterized by a failure in the renal excretion of acids generated through metabolism and for which there is no approved treatment. The excess of acids thus accumulated in the blood leads to an imbalance in pH (acidosis) as well as multiple other complications such as growth retardation and rickets (a disease affecting bone development) in children, and a series of metabolic disorders such as low potassium levels, elevated calcium in the urine resulting in kidney stones, the formation of calcium deposits in the kidneys (calcinosis) as well as possible kidney failure.
