About

This is a prospective, six-week, randomized, double blind, placebo-controlled, multi-center study in patients with schizophrenia who are experiencing an acute exacerbation of psychosis.

Full description

This study consists of a 5- to 14-day screening period to include antipsychotic medication washout, followed by a six-week double blind treatment period. Patients completing the 6-week treatment period may continue double-blind treatment in an optional extension period of at least 6 weeks' duration. Patients randomized to placebo during the initial 6-week period will be randomized to BL-1020 low or high dose during the extension treatment period. Approximately 40 study centers in four countries will participate.

Enrollment: 360 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
