About this study

Official title: An Open-Label and Double-Blind Study to Investigate Evoked Potentials as Markers of Ketamine-induced Cortical Plasticity in Subjects With Major Depressive Disorder

To evaluate if somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) obtained with electroencephalography (EEG) and electromyography (EMG) can be used to detect changes in cortical plasticity in responders to a single IV infusion of ketamine as compared to non-responders.

Read the detailed description

This study will be conducted in patients with Major Depressive Disorder (MDD) and divided into 2 sequential cohorts. Cohort 1 will be conducted in 12 patients at a single center. For each patient, there will be up to 4 sequential phases: a screening phase of up to 6 weeks, an open-label treatment phase of up to 4 weeks, an optional open-label treatment phase of up to 1 week, and a follow-up phase of up to 1 week (if applicable). Cohort 2 will be conducted in 20 patients and will be a multicenter, double-blind (neither physician nor patient knows the treatment that the patient receives), randomized (the study drug is assigned by chance), placebo-controlled (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial) design. For each patient, there will be up to 4 sequential phases: a screening phase of up to 6 weeks, a double-blind treatment phase of up to 4 weeks, an optional open-label treatment phase of up to 1 week, and a follow-up phase of up to 1 week (if applicable). The total study duration for each patient will be maximally about 12 weeks. Participant safety will be monitored throughout the study.

What participants receive

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

  • KetamineDrug

    During Cohorts 1 and 2, a single ketamine 0.5 mg/kg dose will be given as a continuous IV infusion over 40 minutes by use of an electronic syringe infusion pump. The predefined dose and infusion rate/duration should not be adjusted. If a patient is unable to tolerate the study medication, the infusion should be stopped. Within 1 week of completion of the open-label treatment phase, participants can receive a single dose of ketamine 0.5 mg/kg administered as an IV infusion over 40 minutes during an optional open-label treatment phase.

  • PlaceboDrug

    During Cohort 2, a single placebo dose will be given as a continuous IV infusion over 40 minutes by use of an electronic syringe infusion pump. Within 1 week of completion of the double-blind treatment phase, participants can receive a single dose of ketamine 0.5 mg/kg administered as an IV infusion over 40 minutes during an optional open-label treatment phase.

What is being measured

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

  1. Comparison of Ketamine Responders and Ketamine Non-responders in the Change From Baseline in Somatosensory Evoked Potential (SEPs) Amplitudes at 4 Hours Postdose on Day 1

    SEPs are the electrical signals generated by the nervous system in response to somatosensory stimuli - typically through electrical stimulation of the median nerve. SEPs are read on the skull with electroencephalography (EEG). SEPs was recorded using a 64-channel EEG system at baseline (predose) and regularly after study drug administration. The change from baseline was calculated as post-baseline value minus baseline value for each participant. Since the number of participants at baseline differ from the number of participants at post-baseline measure (that is [i.e.] not all baseline values are paired), the mean change is not equal to the difference between the means at the two time points.

    Measured: Baseline and Day 1 (4 hours postdose)

  2. Comparison of Ketamine Responders and Ketamine Non-responders in the Change From Baseline in Motor Evoked Potential (MEPs) Amplitudes at 4 Hours Postdose on Day 1

    MEPs are generated when stimulation of the brain on the motor cortex (with Transcranial Magnetic Stimulation [TMS]) causes the spinal cord and peripheral muscles to produce neuroelectrical signals. MEPs are typically measured in the hand muscles. The Motor Evoked Response to Transcranial Magnetic Stimulation (TMS MEPs) was evaluated at baseline and regularly after study drug administration. Intracortical inhibition and facilitation was also evaluated using TMS. A figure-of-eight coil with external loop diameters of 9 cm was used to elicit motor responses in the contralateral first dorsal interosseus.

    Measured: Baseline and Day 1 (4 hours postdose)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ketamine in people with Major Depressive Disorder, run by Janssen Research & Development, LLC 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 7 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 27 Jan 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 27 Jan 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?

Comparison of Ketamine Responders and Ketamine Non-responders in the Change From Baseline in Somatosensory Evoked Potential (SEPs) Amplitudes at 4 Hours Postdose on Day 1 (time frame: Baseline and Day 1 (4 hours postdose)). The study lists 2 primary outcomes in all. 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 27 Jan 2017.
