ITI-007 (Lumateperone Tosylate) for Schizophrenia

ITI-007 (Lumateperone Tosylate) for Schizophrenia

The purpose of this study is to offer open label ITI-007 treatment to patients who poorly respond or poorly tolerate approved medications.

Patients will be started on ITI-007 and current medication will be slowly discontinued within the first 7 days of starting ITI-007, with some flexibility allowed if clinically indicated. No patients will be left unmedicated because of this study.

Patients will be seen weekly for the first 4 weeks, biweekly for the second month and then monthly for six months. Patients will be monitored by clinical and safety rating scales, and will be required to show improvement after 3 months to remain in this study. Patients not improving at this time will be assessed for the risks/benefits of continuing.
