FDA Approves Otsuka/Lundbeck Schizophrenia Drug

Share

FDA has approved an Otsuka America Pharmaceutical and Lundbeck NDA for Abilify Asimtufii (aripiprazole) a once-every-two-months injection for treating schizophrenia in adults or for maintenance monotherapy treatment of Bipolar I disorder in adults. The companies note that the extended-release intramuscular injectable suspension is not approved for treating patients with dementia-related psychosis.

The aripiprazole concentrations of Abilify Asimtufii were assessed in a pharmacokinetic bridging study. “The once-every-two-months, long-acting injectable formulation in 960 mg and 720 mg prefilled syringes delivers sustained plasma concentrations comparable that demonstrated in studies with Abilify Maintena, a long-acting injectable, resulting in comparable safety and efficacy,” the companies say.

“Results from the pivotal trial 031-201-00181, that enrolled 266 patients, demonstrated that Abilify Asimtufii 960 mg met the primary endpoint criteria establishing similarity of aripiprazole plasma concentrations and thus comparable effectiveness to Abilify Maintena 400 mg over a two-month dosing interval,” they say.
