  5. The main background antipsychotic with which the subject is being treated must continue be one of the antipsychotics listed below:

    • Aripiprazole

    • Asenapine
    • Risperidone
    • Risperidone long-acting injection

  2. A urine drug screen (UDS) result at Baseline that indicates the presence of any tested prohibited substance of potential abuse, except marijuana

    a. Patients with a result indicating the presence of marijuana are permitted if they agree to abstain from marijuana use during the study and the medical monitor approves the subject's participation

  3. Is taking a medication or drug or other substance that is prohibited according to this protocol
  4. Known family or personal history or symptoms of long QT syndrome
  5. Patient has current evidence of a serious and/or unstable psychiatric, neurologic, cardiovascular, respiratory, gastrointestinal, renal, hepatic, hematologic, or other medical disorder, including cancer or malignancies, which would affect the patient's ability to participate in the program.
