About this study
The Johns Hopkins Department of Psychiatry is conducting a research study to examine the effectiveness of riluzole in treating the depressed phase of bipolar disorder. This outpatient treatment study of medication or placebo will last 9-12 weeks. The study includes medical and psychiatric evaluations as well as time-limited medication treatment at no cost, and you will be compensated for your participation.
Read the detailed description
The study will last 8 to 12 weeks and requires weekly visits. Participants will come to Johns Hopkins for a screening visit during which they will talk with a psychiatrist, answer questions about their mood and symptoms, have their blood drawn and have a brief physical exam. If they meet criteria for the study, any antidepressant medication that they are taking will be tapered and stopped before beginning study medications. Participation in the study includes free study medication, labs, and testing plus reimbursement for transportation. Participants will also be paid and after the study referred back to their treating psychiatrist with treatment recommendations.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RiluzoleDrug
Also called Rilutek
Initially dispensed 50 mg capsules to take twice a day (BID). At two weeks, increase dose to 50 mg/100 mg. At four weeks increase to 100 mg BID (two capsules in the morning (qAM), two capsules in the evening (qHS). If significant side effects occur (at any time), titration can be slowed and doses can be reduced to a minimum daily dose of 50 mg/day, after which titration may resume by no more than 50 mg a week. Subjects who are unable to tolerate the minimal daily dose permitted in the study will be discontinued from further participation. In addition, if clinical remission is observed at a lower dose of study medication (defined as Montgomery Asberg Depression Rating Scale (MADRS) < 12) the dose will not be increased further unless clinical symptoms recur.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score From Baseline to the End of 8 Weeks of Therapy.
The Montgomery Asberg Depression Rating Scale measures symptoms of depression (MADRS) is a semi-structured interview rating scale for depression that assesses 10 symptoms. The scale is composed of 10 questions with a fixed 7 point scale (0-6). Total score ranges from 0-60. A higher score indicates more depressive symptoms. MADRS Response will be defined as a > 50% reduction in MADRS score from baseline.
Measured: 8 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Riluzole in people with Bipolar Disorder, run by Johns Hopkins University 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 5 inclusion and 8 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 11 Apr 2017. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 11 Apr 2017). 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?
Mean Change in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score From Baseline to the End of 8 Weeks of Therapy. (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00376220, which also lists 2 linked publications.
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 11 Apr 2017.
