General information about the trial
|
|||
Main objective of the trial |
The purpose of this study was to evaluate the time to relapse after discontinuation of RLAI (Risperidone Long Acting Injection) in first- episode subjects successfully treated for 2 years with RLAI. The relapse rate after treatment discontinuation, the time to response after re-exposure to treatment with RLAI and the degree of clinical improvement measured by PANSS were also evaluated.
|
||
Protection of trial subjects |
Safety was evaluated based on analysis of adverse events, clinical laboratory tests (hematology, serum chemistry, prolactin), vital sign measurements, electrocardiogram (ECGs), physical examinations, extrapyramidal symptoms (EPS), body weight and body mass index (BMI), and waist/hip circumference.

Recruitment
|
|||||||||||||||||||
Recruitment details |
A total of 33 subjects entered Period 1 and discontinued their existing antipsychotic treatment. None of the subjects completed the 36-month follow-up period. A total of 31 subjects entered Period 2 and restarted Risperidone Long-Acting Injection (RLAI) treatment. Overall, 14 of the 31 subjects in Period 2 completed the 24 month treatment period. | ||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||
Screening details |
In Period 1, existing RLAI treatment was discontinued. Subjects who experienced a relapse during Period 1 were transferred into Period 2, at which time RLAI and oral risperidone treatment was initiated simultaneously. Risperidone LAI was initiated at a dose of 25 milligram (mg) once every 2 weeks and continued for a maximum of 2 years in Period 2. | ||||||||||||||||||

Notes [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period. Justification: Not all the enrolled subjects were treated with study drugs. As baseline only included treated subjects, the worldwide number enrolled in the trial differs with the number of subjects reported in the baseline period |
