The purpose of this study is to evaluate the outcome of medication discontinuation, the safety and effectiveness of re-initiating risperidone long acting injection (RLAI) in case of relapse (the return of a medical problem) of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) during the study observation period of 36 months.
This is an open-label (all people know the identity of the intervention), prospective (study following participants forward in time), single-arm, single-center study to assess the consequences of treatment discontinuation and evaluate clinical response to re-initiation of risperidone in case of relapse. The study will consist of 2 periods: Period 1 and Period 2. Participants who were on RLAI for 24 months and in remission (when a medical problem gets better or goes away at least for a while) state will enter in Period 1. In Period 1: RLAI will be tapered and discontinued over a period of 6 weeks. Participants will be regularly and carefully followed-up until their first disease relapse or a maximum of 36 months. In case of relapse (i.e., participants experience the same or similar symptoms to those experienced at the time of study entry in the previous Study RIS-PSY-301), participants will be transferred from Period 1 to Period 2. In Period 2, participants will re-start medication with RLAI (25 milligram [mg], 37.5 mg, or 50 mg [maximum]) and simultaneously start on oral (taken by mouth) risperidone (1 mg, 2 mg, or 3 mg). Doses will be adjusted at Investigator's discretion. Oral Risperidone will only be given for the first 3 weeks until the RLAI injection becomes effective. RLAI injections will continue for up to a maximum of 24 months. Participants will be followed-up until a (new) relapse or the treatment stopped, during a maximum of 24 months. The total duration of the study will be 36 months and will include 16 visits. Assessments will be performed every 2 months in the first year and every 3 months during the following 24 months period. Time to relapse and rate of relapse will be measured as primary outcome for Period 1 and degree of clinical improvement will be measured by Positive And Negative Syndrome Scale (PANSS) total score for schizophrenia. Time to response after re-exposure to treatment with RLAI will be measured as primary outcome for Period 2. Participants' safety will be monitored throughout the study.

|---|---|---|---|
| Risperidone Long-Acting Injection (RLAI) (Period 1) | Experimental | Participants will receive 25 milligram (mg) to 50 mg of RLAI intramuscularly (into the muscle) which will be tapered and discontinued over a period of up to 6 weeks. Participants will be followed-up until their first disease relapse or maximum of 36 months. |
|
| Oral risperidone and RLAI (Period 2) | Experimental | Participants who will experience a disease relapse, will receive RLAI 25 mg, 37.5 mg, or 50 mg, every 2 weeks as an intramuscular injection in the gluteus (a muscle) for up to 24 months. Supplementation with oral risperidone 1 mg or 2 mg or 3 mg will be administered for 21 days from the first dose of RLAI (until RLAI injections becomes effective) and then taper off over the next 5 days. Thereafter, oral risperidone can be administered at the discretion of the Investigator if additional antipsychotic medication will be required due to acute exacerbation of symptoms between visits. |
