This study is designed as a 3-part trial to evaluate the safety of a novel depot formulation of iloperidone, compare 2 depot dosage forms, and perform dose ranging of 1 chosen form in support of a monthly depot dosing regimen. In Phase A, the study is designed to evaluate the safety of a crystalline iloperidone depot formulation. In Phase B, the pharmacokinetic and safety profile of 2 depot clinical dosage forms will be compared, and 1 form will be selected for assessment in Phase C. Phase C of this study is designed to define the dose-exposure relationship of the selected form and to provide information that will permit a comparison of the risk-benefit ratio of several doses of the study drug to enable optimal dose selection for later studies.

Primary | Maximum Observed Plasma Concentration (Cmax) of Iloperidone Divided by the Average Plasma Concentration (Cav) of Iloperidone (Cmax/Cav) - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. | Pre-dose to 26 days post-dose | No |
Primary | The Average Plasma Concentration (Cav) of Iloperidone - Phase C | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. Blood samples were collected after each depot injection. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. Cav was calculated as AUC0-672h/672 h. | Pre-dose to 26 days post-dose | No |
Secondary | Time to Reach the Maximum Plasma Concentration (Tmax) of Iloperidone - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. | Pre-dose to 26 days post-dose | No |
Secondary | Maximum Observed Plasma Concentration (Cmax) of Iloperidone - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. | Pre-dose to 26 days post-dose | No |
Secondary | Area Under the Plasma Concentration-time Curve From 0 to the End of the Dosing Period (AUCtau) of Iloperidone - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. The area under the curve was calculated using a linear trapezoidal method. The end of the dosing period was 672 hours (28 days). | Pre-dose to 26 days post-dose | No |
Secondary | Area Under the Plasma Concentration-time Curve From 0 to the Last Measurable Concentration (AUClast) of Iloperidone - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods.

Secondary | Duration That the Concentration of Iloperidone Was Above 4 ng/mL (Teff) - Phase B | Blood samples for pharmacokinetic (PK) evaluation were drawn pre-dose and at 3, 6, and 12 hours on Day 1; at 0 and 12 hours on Day 2; and on Days 3, 4, 6, 8, 10, 14, 18, 22, and 26 following administration of iloperidone. PK parameters were calculated from plasma concentration-time data using non-compartmental methods.
