Review follows case of fulminant liver failure

The European Medicines Agency (EMA) has started a review of the medicine Zinbryta (daclizumab) used to treat adults with relapsing forms of multiple sclerosis (a disease in which inflammation damages the protective sheath around the nerve cells in the brain and spinal cord). The review follows the death from fulminant liver failure of a patient who was treated with Zinbryta in an ongoing observational study, as well as four cases of serious liver injury.

At its May meeting, the Pharmacovigilance Risk Assessment Committee (PRAC) has completed its review of factor VIII medicines to evaluate the risk of developing inhibitors in patients with haemophilia A who have not previously been treated with these medicines.

Factor VIII is needed for blood to clot normally and is lacking in patients with haemophilia A. Factor VIII products replace the missing factor VIII and help control bleeding. However the body may develop inhibitors as a reaction to these medicines, particularly in patients starting treatment for the first time. This can block the effect of these medicines, so bleeding is no longer controlled.

The review was started following publication of a study which concluded that inhibitors develop more frequently in patients receiving recombinant factor VIII medicines than in those receiving plasma-derived factor VIII medicines. The PRAC concluded that there is no clear and consistent evidence of a difference in inhibitor development between the two classes of factor VIII medicines.

EMA’s Pharmacovigilance and Risk Assessment Committee (PRAC) has recommended the suspension of the marketing authorisations for four linear gadolinium contrast agents because of evidence that small amounts of the gadolinium they contain are deposited in the brain.

EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) is warning that an increase in cases of lower limb amputation (mostly affecting the toes) has been observed in patients taking the type 2 diabetes medicine canagliflozin compared with those taking placebo (a dummy treatment) in two clinical trials, CANVAS and CANVAS-R. The studies, which are still ongoing, involved patients at high risk of heart problems.

Review follows data on toe amputations in ongoing study

The European Medicines Agency (EMA) has started a review of the diabetes medicine canagliflozin after an increase in amputations, mostly affecting toes, was observed in an ongoing clinical trial called CANVAS. Cases of lower limb amputation occurred in both the canagliflozin and placebo groups in the trial and the possibility that canagliflozin increases lower limb amputations is currently not confirmed. EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) has requested more information from the company to assess whether canagliflozin causes an increase in lower limb amputations and whether any changes are needed in the way this medicine is used in the EU.
