Ability to comprehend the full nature and purpose of the study, including possible risks and adverse events; ability to co-operate with the Investigator and to comply with the requirements of the entire study. 6. Patients/Legally Acceptable Representative has given written consent after being advised of the nature and risks of the study. 7. Patients must have adequate hematologic reserve i.

Patients with medical or surgical condition that might interfere with the absorption, metabolism, or excretion of Clozapine or other study medications. 5. Patients with history of granulocytopenia or myeloproliferative disorder, either drug-induced or idiopathic. 6.
