Combination Therapy in Dual Diagnosis Bipolar Rapid Cycling: This study recruits males and females age 18 and older who currently meet diagnostic criteria for rapid cycling bipolar disorder (type I or II) and who have met the criteria for substance abuse or dependence of cocaine, marijuana and/or alcohol within the past six months. Patients begin treatment with a combination of lithium and divalproex. Once these medications are tolerated, they are randomly assigned to double-blind treatment with lamotrigine or placebo. Patients remain in this study until they experience a marked bimodal response for four consecutive weeks. This study is sponsored by the Stanley Foundation.

Primary Outcome Measures:
  • Proportion of patients who experience a marked and persistent bimodal response
  • Time to response while on blinded study medication

Estimated Enrollment: 150
Study Start Date: July 2002
Study Completion Date: December 2007

Ages Eligible for Study:   16 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Has given written informed consent.
  • Males or females 16 years of age and older. For patients less than 18 years old, concurrent written informed consent will also be required from the parents or legal guardians.
  • Must meet DSM-IV criteria for major depression at the time of study entry.
  • Must meet DSM-IV criteria for rapid-cycling bipolar disorder in the last 12 months.
  • Must meet DSM-IV criteria for alcohol or drug abuse within the past 3 months or dependence in the last 6 months (unless most recent period of abstinence occurred while in a controlled environment).
  • Must have no medical illness precluding the use of lithium, divalproex sodium and/or lamotrigine.
  • Regardless of treatment response, patients who have been exposed to lithium or divalproex sodium will be included as long as the medication was adequately tolerated and all three medications were not administered concurrently.

Exclusion Criteria:

  • Patients who have had intolerable side effects to lamotrigine, lithium at levels of 0.6 mEq/L or divalproex sodium at levels of 50ug/ml.
  • Patients who have previously been treated with lithium, divalproex sodium and lamotrigine concurrently.
  • Patients who have previously been treated with an adequate trial of lamotrigine, which was considered to be a treatment failure.
  • Patients who do not have a recent history of, or are not currently abusing or dependent on alcohol or drugs.
  • Patients with a prior history of seizure disorder, cerebral vascular disease, structural brain damage from trauma, clinically significant focal neurological abnormalities, closed head injury, EEG abnormalities with frank paroxysmal activity or a previous CT/MRI scan of the brain with gross structural abnormalities.
  • Patients who have clinically significant gastrointestinal, renal, hepatic, endocrine, cardiovascular, pulmonary, immunologic, hematologic, or oncologic diseases. Clinically significant evidence of thyroid failure will be defined as a decreased free thyroxine index with several clinical signs and symptoms of overt failure.
  • Patients who are pregnant, at-risk of becoming pregnant or intend to become pregnant during the study. Patients who are not at risk of becoming pregnant are females who are post menopausal, who have undergone a hysterectomy, bilateral oophorectomy or sterilization, who agree to use an IUD, barrier protection, a contraceptive implantation system (e.g., Norplant), oral contraceptive pills, or who, in the investigator's judgment, will continue to be sexually inactive.
  • Patients who have received haloperidol decanoate or fluphenazine decanoate within the last 10 weeks.
  • Patients who have a CNS neoplasm, uncontrolled metabolic, demyelinating or progressive degenerative disorder, active CNS infection, or any progressive neurological disorder.
  • Patients who are taking exogenous steroids.
  • Patients who have ultra-fast rapid-cycling bipolar disorder, but do not formally meet DSM-IV criteria for bipolar disorder. This is designed to exclude patients with episode frequencies too high to permit objective quantification.
  • Patients who are currently suicidal in the opinion of the investigator or have a score of greater than 4 on the suicide item of the MADRS.
  • Patients who have been treated with any dose or duration of a tricyclic antidepressant within the last three months.
