This is a randomized, open-label, parallel-group, single-dose study. Patients will undergo screening evaluations to determine eligibility within 28 days prior to study drug administration. About 36 patients will be randomized in a 1:1:1 ratio to 1 of 3 treatment groups. Patients will be admitted to the clinical facility the day before dosing (Day 0) and will be receiving an IM injection of study drug and completing the assigned study activity including PK sample collection on Day 1. Patients will be discharged on Day 2 after PK collection. All patients will return to the clinical site at designated study days for PK sample collections and assigned clinical procedures. End of study evaluation will be completed on Day 120.~Pharmacokinetics of the study medication will be assessed as primary outcome. Participants' safety will be monitored throughout the study.
The primary objectives of the study are to characterize the pharmacokinetic (PK) profiles of paliperidone in LY03010 P1 and P2 following a single IM injection in schizophrenia patients and to compare the PK of LY03010 P1 and P2 with that of INVEGA SUSTENNA® following a single IM injection of 156 mg dosage level.
