Patent No. EP4025188 (titled "Dosing Regimens Associated With Extended Release Paliperidone Injectable Formulations") was filed by Janssen Pharmaceutica on May 7, 2021. The application was issued on Jan 10, 2024.
Paliperidone palmitate for treating psychosis, schizophrenia, schizoaffective disorder, and bipolar disorder through a novel dosing strategy that enables continuous treatment with once-monthly injections. The dosing regimen involves administering a re-initiation loading dose of the extended-release formulation after a minimum six-month gap from the initial injection, followed by maintenance doses. This approach addresses the common challenge of medication adherence by providing a continuous therapeutic effect while minimizing the need for frequent clinic visits.
