About this study

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.

Read the detailed description

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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard of CareDrug

    Also called Quetiapine, Olanzapine, fluoxetine

    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.

  • KetamineDrug

    Also called Ketamine Hydrochloride

    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-cycloserineDrug

    Also called DCS

    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.

Study groupRoleWhat they receive
Ketamine and DCS treatmentExperimentalStandard 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hamilton Depression Rating Scale (HAM-D)

    Depression rating scale: Range 0-53, higher scores indicate worse depression. 0-7 = Normal 8-13 = Mild Depression 14-18 = Moderate Depression 19-22 = Severe Depression

    ≥ 23 = Very Severe Depression

    Measured: 8 weeks

Secondary outcomes (4)
  1. Loss of Motivated Behavior HAM-D Factor

    includes the total of four HAM-D items: (Item 7: Work and activities, Item 12. Somatic symptoms (appetite), Item 14. Genital symptoms (libido), and Item 16. Weight loss). Range 0-11, higher scores indicate worse symptoms

    Measured: 8 weeks

  2. HAM-D Suicide Item

    Ham-D suicide item: range 0-4, higher scores indicate worse symptoms

    Measured: 8 weeks

  3. Hamilton Anxiety Scale

    Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where <17 indi- cates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.

    Measured: 8 weeks

  4. Beck's Depression Inventory

    Range 0-63, with higher scores worse. Total score of 0-13 is considered minimal range, 14-19 is mild, 20-28 is moderate, and 29-63 is severe.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ketamine and D-cycloserine in people with Bipolar Disorder, run by New York State Psychiatric Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Jun 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hamilton Depression Rating Scale (HAM-D) (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2016.
