Review of sickle cell disease medicine Adakveo started

EMA has started a review of Adakveo, a medicine for preventing painful crises (called vaso-occlusive pain crises) in patients with sickle cell disease.

The review was prompted by preliminary results from an ongoing study in patients with sickle cell disease which indicate that, after one year of treatment, Adakveo did not reduce the number of painful crises leading to a healthcare visit compared with placebo (a dummy treatment). The study, called the STAND study, looks at the effectiveness and safety of Adakveo compared with placebo in adolescents and adults who had previously had painful crises leading to a healthcare visit. Data from this study were requested by EMA as part of the conditions to the marketing authorisation.

EMA will review these findings in the context of all available data and assess their impact on the benefit-risk balance of Adakveo in its approved indication. The Agency will then recommend whether the medicine’s marketing authorisation should be amended.

A letter will be sent in due course to relevant healthcare professionals to inform them of these preliminary results and the ongoing review. The letter will also be published on the EMA website.
