  3. Subjects must have moderate-to-severe hypomania or mild mania within the past 2 weeks, defined as having a YMRS >10 and < 21 at the baseline assessment.
  4. Subjects' overall bipolar symptoms must be clinically significant but not greater than severe (defined as a CGI-BP >2 and < 5).
  5. Subjects must be outpatients.
  6. Subjects must be on no psychotropics for 1 week (2 weeks for fluoxetine and 4 weeks for depot antipsychotics) except for prn lorazepam (.5-2mg/day) or zaleplon (5-10mg qhs).

Exclusion Criteria:

  1. Subjects who do not have bipolar disorder by above DSM-IV-TR criteria.
  2. Subjects whose bipolar symptoms are more than severely ill (CGI-BP > 5, YMRS > 21, or IDS > 39).
  3. Subjects who are receiving treatment with an antimanic or mood stabilizing medication (lithium, valproate, or an antipsychotic), and in the investigators' judgment, require ongoing treatment with that medication.
  4. Subjects who require hospitalization.
