A Study of the Safety, Tolerability and Pharmacokientics of RO5545965 in Patients With Schizophrenia on Risperidone

1. november 2016 opdateret af: Hoffmann-La Roche

A SINGLE-CENTER, RANDOMIZED, INVESTIGATOR/SUBJECT-BLIND, MULTIPLE-DOSE, PLACEBO-CONTROLLED, PARALLEL STUDY TO INVESTIGATE THE SAFETY, TOLERABILITY AND PHARMACOKINETICS OF RO5545965 IN PATIENTS WITH SCHIZOPHRENIA ON RISPERIDONE.

This randomized, double-blinded, placebo-controlled study will investigate the safety, tolerability, and pharmacokinetics of multiple doses of RO5545965 administered orally to psychiatrically stable patients with schizophrenia receiving risperidone.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Placebo komparator: Placebo + risperidone
Andet: Placebo
Oral daily administration from Days 1-12
Medicin: risperidone
13 day run-in phase until 4 mg daily dose level is reached. 4 mg daily oral dose until Day 17 of study, for a total of 30 days. Dose may be increased up to 6 mg at the investigator's discretion. After study treatment, risperidone dosage may be decreased, increased or omitted at the investigator's discretion during a wash-out phase while patients return to their chronic antipsychotic treatment. Patient response during wash-out will be monitored in-house for 48 hours after the last dose of RO5545965 or placebo is administered. This in-house observation may be extended as needed by the investigator.
Eksperimentel: RO5545965 + risperidone
