November 1, 2016 updated by: Hoffmann-La Roche

A Phase II, Multi-center, Randomized, 4-week, Double-blind, Parallel Group, Placebo and Active-controlled Trial of the Safety and Efficacy of RO4917838 vs. Placebo in Patients With an Acute Exacerbation of Schizophrenia

This randomized, double-blind, placebo- and active-controlled, parallel group study will evaluate the safety and efficacy of RO4917838 (bitopertin) in patients with acute exacerbation of schizophrenia. Patients will be randomized to receive either RO4917838 10 mg or RO4917838 30 mg or olanzapine 15 mg or placebo orally daily for 4 weeks as inpatients, with a 4-week follow-up period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Change in Positive and Negative Syndrome Scale (PANSS) total score
Time Frame: from baseline to Day 28
from baseline to Day 28
Safety: Incidence adverse events
Time Frame: 8 weeks
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Clinical response, defined as at least 30% or 50% improvement from baseline PANSS total score
Time Frame: from baseline to Day 28
from baseline to Day 28
Change in symptomatology as measured by the PANSS factor and subscale scores
Time Frame: from baseline to Day 28
from baseline to Day 28
Global improvement as measured by the Clinical Global Impressions-Severity (CGI-S) scale
Time Frame: from baseline to Day 28
from baseline to Day 28
Global improvement as measured by the Clinical Global Impressions-Change (CGI-C) rating scale
Time Frame: from baseline to Day 28
from baseline to Day 28
Observable behavioural change as determined by the Nurses' Observation Scale For Inpatient Evaluation (NOSIE)

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
