About this study

Official title: A Randomised, Parallel Group, Double Blind, Placebo Controlled, Add on Clinical Trial to Investigate Whether the Lithium Mimetic, Ebselen, Can Reduce Symptoms of Hypomania and Mania in Bipolar Patients

This study evaluates the effect of a 'lithium like' drug called ebselen (SP-1005) versus placebo as an 'add on' treatment to help stabilise hypo/manic symptoms in bipolar disorder. Half of the participants will receive ebselen and the other half placebo. The trial, will last a total of four weeks.

Read the detailed description

Ebselen, a new drug for mania

Bipolar disorder, formerly known as manic depression, is a condition that affects mood, which can swing from one extreme to another.

Typically, there will be periods of:

  • Depression - very low mood and energy levels
  • Mania or hypomania (less severe) - very high mood and overactive energy levels

A drug called lithium, used to stabilise mood, is an important treatment for bipolar disorder but has a number of problematic side effects, is not well tolerated by patients and requires careful monitoring. To replace lithium with other, safer medicines would have clear advantages. The investigators are interested in an antioxidant medicine(substance that may prevent or delay cell damage) called ebselen which has been shown to work in a similar way as lithium and the investigators are investigating whether it might help improve recovery from manic episodes.

The present study aims to see whether ebselen, used as an 'add-on' treatment can help stabilise mood in patients experiencing high mood (hypo/mania). Sixty patients experiencing hypo/mania will be given in a randomised order (similar to tossing a coin) either ebselen or placebo (dummy) in addition to their usual medication for three weeks after which the add-on treatment will be stopped. A final follow up visit will take place one week after the study medication has been stopped. Participants can be in or outpatients and mood will be monitored with questionnaires and interviews. Activity will also be monitored with the use of an actiwatch (similar to a wrist watch) which will be worn continuously throughout the study. A single blood sample will be optional and occur after the first week of treatment to check plasma levels of ebselen and inflammatory markers. A positive outcome in this trial will be followed by longer term studies of ebselen in bipolar disorder.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ebselen in people with Bipolar Disorder and Bipolar Disorder, Manic, run by University of Oxford at 1 site in United Kingdom.

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 7 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 6 Sep 2019. 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 Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in Young Mania Rating Scale (YMRS) (time frame: Change between groups, every week, up to 4 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 NCT03013400, which also lists 6 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 6 Sep 2019.
