FDA OKs Rexulti for Alzheimer’s Agitation
FDA has approved an Otsuka Pharmaceutical and Lundbeck supplemental NDA for Rexulti (brexpriprazole) oral tablets for treating agitation associated with dementia due to Alzheimer's disease. Approval was based on data from two 12-week, randomized, double-blind, placebo-controlled studies. “In both studies, patients who received 2 mg or 3 mg of Rexulti showed statistically significant and clinically meaningful improvements in total CMAI [Cohen-Mansfield Agitation Inventory] scores compared to patients in the placebo group at week 12,” an agency release says.
Common side effects, according to the agency, included headache, dizziness, urinary tract infection, nasopharyngitis, and sleep disturbances. “Rexulti will retain the Boxed Warning for medications in this class that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death,” it adds.
The approval follows the advice FDA received last month (see story) at a joint meeting of the Psychopharmacologic Drugs Advisory Committee and the Peripheral and Central Nervous System Drugs Advisory Committee. Panel members voted 9 to 1 that the companies provided sufficient data to allow identification of a population in whom the benefits of treating agitation associated with Alzheimer’s dementia outweigh the drug’s risks. The atypical antipsychotic is already indicated to treat schizophrenia and major depressive disorder.
