The primary objective of this study is to demonstrate the bioequivalence, with respect to risperidone and its active moiety, of a single oral dose of risperidone given as a 4 mg orally-disintegrating tablet and as a 4 mg conventional RISPERDAL tablet. In addition, their tolerability and safety will be documented.

Clinical Details

Official title: A Bioequivalence Study Comparing a Single Oral Intake of a 4mg Orally-disintegrating Tablet With a 4mg Conventional Risperdal Tablet in Patients With Schizophrenia

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: PK parameters (Cmax and AUC) for active moiety, 9-OH-risperidone and risperidone

Secondary outcome: Safety assessments including adverse events, physical examination, vital signs, ECGs and labs

Detailed description: This is a single-center, open, randomized, 2-way crossover bioequivalence study in 40 subjects with schizophrenia or schizoaffective disorder. The study will consist of 2 treatment periods, 5 days per period. The subjects will receive a single 4 mg RISPERDAL conventional tablet in period 1 and a single 4 mg orally-disintegrating tablet in period 2; or the orally disintegrating tablet in period 1 and conventional tablet in period 2. A washout period of at least 10 days between Day 1 of Period 1 and Day 1 of Period 2 will separate the 2 treatments. In both treatment periods plasma concentrations of the drug will be measured. Serial blood collections will be made beginning at 0 hour (immediately before study drug administration) and continuing up to 96 hours after study drug administration in each period. Safety will be evaluated throughout the study using physical examinations, electrocardiogram recordings (ECG), clinical laboratory testing (hematology, serum chemistry, urinalysis), vital signs measurements, pregnancy testing, drug screening, and monitoring of adverse events. The study will be approximately 6 weeks long (including the screening period). Subjects will enter the study facility 3 days before the first administration of study medication on Day 1 of the first period. They will remain at the facility until all study-related procedures are completed on Day 5 of the second study period, a period of approximately 18 days. 4 mg risperidone (either conventional tablet or orally-disintegrating tablet), single dose, oral intake


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.
