NMDA Antagonists in Bipolar Depression
Brief Summary
The purpose of this study is to test whether ketamine and D-cycloserine can be safely and effectively used for the treatment of depression. The investigators hypothesize that ketamine will serve as a rapid acting and safe antidepressant in patients with bipolar depression, and furthermore, that D-cycloserine will serve as an effective therapy following ketamine treatment.
Intervention / Treatment
-
Standard of Care (DRUG)Quetiapine, olanzapine-fluoxetine, and lurasidone are approved treatments for bipolar depression. Quetiapine dosing will follow the product label(Anon), and will be titrated over the first 4 days to the target dose of 300 mg. Olanzapine-fluoxetine dosing will also follow standard guidelines. Lurasidone will be started at 20 mg, and titrated up to 60 mg daily as clinically indicated. Study physicians will use clinical judgment to choose between standard-of care treatments, and have the option to titrate standard-of-care within approved ranges, and to prescribe adjunctive benztropine and benzodiazepines if clinically indicated.
-
Ketamine (DRUG)Ketamine administration will be carried out according to the methods as described by previous studies. Subjects will receive ketamine hydrochloride (0.5 mg/kg) intravenously during 40 minutes. This dosage was selected based on previous trials of ketamine for the treatment of refractory depression and bipolar depression. Vital signs (blood pressure, heart rate) will be closely monitored throughout the time of infusion. Subjects will be evaluated for 2 consecutive days during this phase; i.e. treatment days (day 1) and rating days (day 2). Non-responders to ketamine will not proceed into the DCS phase. Response will be a 25% improvement on the Hamilton Depression Rating Scale (HDRS).
-
D-cycloserine (DRUG)Immediately after the ketamine infusion, subjects will begin an eight-week treatment of DCS adjunctive to standard of care. DCS dosing will begin at 250 mg for three days→500mg (2 capsules)/day for 1 week → 750 mg (3 capsules)/day for 1 week → and 1000 mg (4 capsules)/day for the remainder of the study.

Location
Bipolar disorder affects 2% of the population in the United States and the depressive phase contributes disproportionally to morbidity and mortality. At present, few approved treatments for bipolar depression are available, and have primarily depended on manipulations of brain monoaminergic systems. In contrast, recent studies suggest that the N-methyl-D-aspartate glutamate-receptor (NMDAR) antagonist, ketamine, may provide near-immediate relief for treatment resistant depression. Its utility during long-term treatment, however, is limited by its psychotomimetic potency and the need for repeated IV infusions. D-cycloserine (DCS) is an approved oral antibiotic for tuberculosis drug and a well-studied mixed agonist/antagonist at the NMDAR/glycine binding site. DCS showed preliminary evidence of efficacy in a pilot study. DCS would thus be practical from both a safety and route of administration perspective. The present study will explore the feasibility and safety of DCS for maintenance treatments, as measured by magnetic resonance spectroscopy (MRS).
Participant Groups
-
Standard of Care: Subjects will receive treatment with either quetiapine, olanzapine-fluoxetine, or lurasidone. If after about 2 week, subjects are symptomatic, subjects will receive infusion of ketamine hydrochloride (0.5 mg/kg). After the ketamine phase, subject who show improvement will begin an 8-week treatment of oral D-cycloserine.
Eligibility Criteria
| Sex: | All |
|---|---|
| Minimum Age: | 18 |
| Maximum Age: | 60 |
| Age Groups: | Adult |

Inclusion Criteria:
* Male and female patients with Diagnostic and Statistical Manual, Version 4 (DSM-IV) diagnosis of bipolar disorder I or II, current major depressive episode without psychotic features, 18-60
* Insufficient therapeutic response during the current episode
* Medically stable for study participation
* Judged clinically not to be at significant suicide or violence risk
* Subject is off all psychotropic and other types of drugs likely to interact with glutamate for at least 14 days before starting the study. One exception is chloral hydrate or short acting benzodiazepines for distressing anxiety or insomnia (up to 72 hours prior to each MRI scan). In addition, subjects will be off antipsychotics for 1 month and off fluoxetine for 6 weeks prior to the study.
