FDA Approves Rexulti for Pediatric Patients
FDA has approved an Otsuka America Pharmaceutical and H. Lundbeck supplemental NDA for Rexulti (brexpiprazole) for treating schizophrenia in pediatric patients 13 to 17 years of age. Rexulti was originally approved in 2015 for treating schizophrenia in adults and for adjunctive treatment of major depressive disorder in adults.
The sNDA was supported an extrapolation analysis that relied on data from prior studies among adult patients, pharmacokinetic results from adult and pediatric trials, and six-month data from an ongoing open-label, long-term trial among adolescent patients with schizophrenia, according to the company.
Brexpiprazole was discovered by Otsuka and is being co-developed by Otsuka and Lundbeck. The companies say that while the drug’s mechanism of action is not fully understood, its efficacy may be “mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, and antagonist activity at serotonin 5-HT2A receptors. Brexpiprazole exhibits high affinity (sub-nanomolar) for these receptors as well as for noradrenaline alpha1B/2C receptors.”
