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

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.

Primary outcomes

  1. Extrapyramidal Symptoms Assessed by Abnormal Involuntary Movement Scale (AIMS) - Change From Baseline in AIMS Component Movement

    Time frame: Overall - Change from Baseline to End of Study (Day 17)

    AIMS is a rating scale to measure tardive dyskinesia (TD). For the scoring, the AIMS scale has 14 items. The first 10 items (under categories of Facial and Oral Movements, Extremity Movements, Trunk Movements, and Global Judgements) are rated from 0 (none) to 4 (severe); the remaining 4 items (Dental Status) are rated "yes" and "no" and not counted. The analysis is limited to items 1 to 10, with each rated from 0 to 4. The total score is the sum of all 10 items and with values ranging from 0 to 40. Overall change from baseline to End of Study (Day 17) in AIMS was reported for the Safety Set. Higher scores imply worse outcome.

  2. Barnes Akathisia Rating Scale (BARS)

    Time frame: Overall - Change from Baseline to End of Study (Day 17)

    BARS is a multiple-choice questionnaire that clinicians may use to provide an assessment of akathisia. The clinician or rater is instructed to observe the subject while standing and while sitting, at least 2 minutes each (total of at least 4 minutes in total). There are 4 areas where the subject is to be evaluated, 1 of these is objective, 2 are subjective, and the final is a global assessment. The BARS scale has 3 items that are rated from 0 (absence/no distress) to 3 (most severe). The BARS rating scale is scored by summing the scales for Objective Akathisia, Subjective Awareness of Restlessness and Subjective Distress Related to Restlessness yielding a total score ranging from 0 to 9. The Total score, which has a possible range from 0-9, is reported. Higher scores imply worse outcome.

  3. Number of Subjects Who Experienced Suicidal Ideation or Behavior Events Per the Columbia Suicide Severity Rating Scale (C-SSRS)

    Time frame: Overall - End of Study (Day 17)

    C-SSRS is a measure to identify and assess individuals at risk for suicide. Questions are phrased for an interview format but can be completed as a self-report measure if needed. It measures 4 constructs: severity of ideation, intensity of ideation, behavior, and lethality. It includes "stem questions," which if endorsed, prompt additional follow-up questions to obtain more information. For the composite endpoint of suicidal ideation or behavior (1-10), the number and percent of subjects in the Overall Safety Set who experience any one of the ten suicidal ideation or behavior events at End of Study (Day 17).
