About this study

Official title: An Open-Label Study of Cysteamine Bitartrate in Treatment-Resistant Major Depression

The purpose of this study is to determine whether cysteamine bitartrate, an FDA-approved drug for a non-psychiatric condition, is safe and effective for the treatment of major depression.

Read the detailed description

Major depressive disorder (MDD) is a chronic, disabling illness affecting about 17% of the general population. Despite advances in treatment, about two-thirds of patients fail to respond to an initial trial of pharmacotherapy. Brain-derived neurotrophic factor (BDNF) is a neural growth-promoting polypeptide found in the central nervous system, and has been implicated in the pathophysiology and potential treatment of MDD. A multitude of studies have shown low levels of BDNF in subjects with MDD, which have normalized after treatment with an antidepressant. Traditional antidepressants such as serotonin reuptake inhibitors may increase BDNF via an indirect intracellular pathway. The current study drug, cysteamine bitartrate (Cystagon), is FDA approved for the treatment nephropathic cystinosis and has been shown to increase BNDF in neuronal tissue, and to stimulate cell growth. Cysteamine has already been investigated in humans as a potential treatment for Huntington's Disease. Given the evidence of decreased levels in major depression, and subsequent increase post-treatment with antidepressants, BDNF may play a key role in developing novel treatments for patients who have failed conventional agents. Therefore, drugs that can demonstrably increase central BDNF, such as cysteamine, may have significant potential as novel antidepressant medications.

What participants receive

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

  • cysteamine bitartrateDrug

    All enrolled participants will begin open treatment with cysteamine on the first visit of the experimental period (after screening, medical clearance and medication washout period if necessary). The dosing schedule is a flexible regimen starting at 150 mg PO three times daily. After one week, patients without intolerable side effects will increase the dose to 300 mg three times daily. The titration schedule will continue up to a maximum of 1800 mg a day. In case of adverse events, the investigator may decrease the dose by 150 mg daily.

What is being measured

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

  1. Montgomery-Åsberg Depression Rating Scale (MADRS)

    This scale measures depression severity. It ranges from a score of 0 to 60, with higher score indicating higher level of depression severity.

    Measured: 8 weeks

Secondary outcomes (3)
  1. Clinical Global Impression Scales for Severity (CGI-S) and Improvement (CGI-I)

    This set of scales measures "global" improvement in a patient's level of symptoms, without reference to a particular condition (ie depression). GCI-S is a measure of severity, which ranges from 0 (not ill) to 7 (severely ill). CGI-I is a measure of change, with a score of 4 indicating no change, 1 indicating very much improved and 7 indicating very much worse.

    Measured: 8 weeks

  2. Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16)

    This is a self-report which measures the level of depression severity. I ranges from 0 (no illness) to 27 (severe illness).

    Measured: 8 weeks

  3. Systematic Assessment for Treatment Emergent Effects (SAFTEE)

    The SAFTEE is used to measure somatic and other symptoms which may arise during the course of a clinical trial. This is a non-quantitative instrument that does not yield a numeric score. Instead, it provides study subjects the opportunity to check off symptoms listed on a checklist and indicate if the severity of the symptoms is "mild" "moderate" or "severe." The reported values represent symptoms that were indicated at any point during the 8 week trial at a level of "moderate" or "severe" that also represented a change from a baseline-line pre-intervention SAFTEE assessment.

    Measured: weekly, for 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing cysteamine bitartrate in people with Major Depressive Disorder, run by Icahn School of Medicine at Mount Sinai 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 8 inclusion and 20 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: stopped early, as of the sponsor's last update on 7 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Jun 2011). 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?

Montgomery-Åsberg Depression Rating Scale (MADRS) (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 7 Apr 2017.
