A Study to Evaluate the Safety, Tolerability, Pharmacodynamics, and Pharmacokinetics of Co-Administration of Roluperidone and Olanzapine in Adult Subjects With Moderate to Severe Negative Symptoms of Schizophrenia

Completed · Phase 1

Conditions studied: Negative Symptoms in Schizophrenia

In brief

The goal of this clinical trial is to evaluate the Safety, Tolerability, Pharmacodynamics, and Pharmacokinetics of the Co-Administration of Roluperidone and Olanzapine in Adult Subjects with Moderate to Severe Negative Symptoms of Schizophrenia. The main question this clinical trial aims to answer are the pharmacodynamic and pharmacokinetic effects and safety of the concomitant therapy of Roluperidone with an established and widely used antipsychotic, such as olanzapine in order to provide further guidance to clinical practitioners that may prescribe off-label use of these drugs concomitantly in clinical practice. Eligible Participants will undergo the following study phases in the clinic: * Screening Phase: Between 2 and up to 28 days during which study eligibility will be established and subjects receiving psychotropics will be washed out. Subjects will remain inpatient at the clinical site at least through the end of Treatment Phase 2. * Treatment Phase 1: After the Baseline Visit, Roluperidone 64 mg/day will be administered as a monotherapy for 7 days (Days 1-7). * Treatment Phase 2: Concomitant administration of Olanzapine 10 mg/day and Roluperidone 64 mg/day for 10 days, starting on Day 8 (Days 8-17). Subjects may be discharged from the clinic at least 48 hours after the last administration of the study drugs and after the collection of the last plasma sample; however, the inpatient period may be extended at the discretion of the investigator. End of Study (EOS): Will take place at least 14 days after the last dose of the study.
