Lundbeck and Otsuka Pharmaceutical have announced that the FDA has determined that the supplementary New Drug Application (sNDA) for brexpiprazole for the use in the treatment of agitation associated with Alzheimer’s dementia (AAD) is sufficiently complete to permit a substantive review.

The FDA has assigned the application priority review and a Prescription Drug User Fee Act (PDUFA) target action date of May 10, 2023. The FDA also indicated that they are currently planning to hold a Psychopharmacologic Drugs Advisory Committee meeting to discuss the application.

“This milestone is important in our efforts to bring patients with Alzheimer’s dementia and their caregivers one step closer to having a potential treatment option that may address a major disabling neuropsychiatric symptom of the disease,” said Johan Luthman, Executive Vice President, Lundbeck Research & Development.

Data from 2 positive Phase III studies

The sNDA submission includes data from two positive clinical phase III studies that investigated the treatment of brexpiprazole in patients with AAD. Study 331-12-283 demonstrated brexpiprazole 2 mg/day was statistically superior to placebo for the primary endpoint of mean change in Cohen-Mansfield Agitation Inventory (CMAI) Total Score from baseline to Week 12 (p < 0.05). In Study 331-14-213, treatment with brexpiprazole 2 and 3 mg/day showed statistically significant improvement compared with placebo for the primary efficacy endpoint, the mean change in CMAI Total Score from baseline to Week 12 (p < 0.05). Brexpiprazole also demonstrated a generally favorable safety and tolerability profile in the studies.
