Brief Summary: This is a single ascending dose phase 1 study to evaluate the pharmacokinetics (PK), safety, and tolerability of a single intramuscular (IM) injection of quarterly Risperidone (QUAR) for different formulations and dose strengths in participants with schizophrenia.
Detailed Description: The study will assess the PK, safety and tolerability of QUAR when administered as a single IM injection, in patients with schizophrenia. The study will be conducted with 3 different dose strengths and up to two formulations.

After eligibility confirmation, an oral treatment period follow by a washout period will be performed before QUAR IM administration.

The different cohorts will be administered with one of the following dosages of Risperidone QUAR:

Cohort 1/2: Formulation 1 or 2. Dose level 1 (Gluteal); Cohort 1a/2a: Formulation 1 or 2. Dose level 2 (Gluteal); Cohort 1b/2b: Formulation 1 or 2. Dose level 3 (Gluteal); Cohort 1c/2c: Formulation 1 or 2. Dose level 3 (Deltoid);

The progression to the next cohorts will take place after a clinical safety assessment. Several blood samples for plasma pharmacokinetic (PK) assessments will be obtained pre-dose and post-dose. Safety assessments will be conducted at each pre-specified time points.

After assessment of Cohort 1 (formulation 1, Dose Level 1, -gluteus-) progression to the next cohort with same formulation and escalating dose will take place (Cohort 1a -gluteus-). After assessment of Cohort 1a, progression and randomization (gluteus/deltoid) to the next cohorts with same formulation and escalating dose will take place (Cohort 1b -gluteus- and Cohort 1c -deltoid-). In this scenario, none of the Cohorts 2 will be conducted.

If the assessment for Cohort 1 is not adequate, none of the subsequent Cohorts 1 (a/b/c) will be conducted and progression to the next cohort (Cohort 2) with different formulation and same level of dose as Cohort 1 will take place (Cohort 2: Formulation 2, Dose Level 1 -gluteus-). After assessment of Cohort 2, progression to the next cohort with same formulation and escalating dose will take place (Cohort 2a -gluteus-). After assessment of Cohort 2a, progression and randomization (gluteus/deltoid) to the next cohorts with same formulation and escalating dose will take place (Cohort 2b -gluteus- and Cohort 2c -deltoid-).
