About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Dose-Escalation Study of NNZ-2566 in Patients With Traumatic Brain Injury

The purpose of this study is to determine whether NNZ-2566 is safe and effective in the treatment of Traumatic Brain Injury (TBI).

Read the detailed description

Moderate to severe traumatic brain injury frequently results in persistent problems with memory, attention span, mood and more complex brain functioning such as planning and organizing. There are currently no drugs available to reduce the brain damage or the persisting symptoms that result from TBI. The longer term goal of this study is to provide physicians with a safe and effective treatment for TBI.

What is being measured

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

  1. Reduced incidence, compared to placebo, of adverse events (AEs) and serious adverse events (SAEs)

    Measured: AEs to discharged or Day 30 post randomization, whichever occurs first, and SAEs through to 3 months (defined as 12-14 weeks), post randomization.

Secondary outcomes (4)

  1. Evidence of efficacy in modifying global outcomes by evaluating Glasgow Outcome Scale - Extended (GOS-E) and activities of daily living (Mayo-Portland Adaptability Inventory - 4th Edition (MPAI-4))

    Measured: 1 month (defined as 4-6 weeks) and 3 months (defined as 12-14 weeks), post randomization.

  2. Improvement in cognitive and neuropsychological functioning.

    Measured: 1 month (defined as 4-6 weeks) and at 3 months (defined as 12-14 weeks), post randomization.

  3. Modification of the acute physiological processes in TBI by evaluating electroencephalographic (EEG) determinants in patients with moderate to severe TBI (defined as GCS 4-12), and biomarker levels.

    Measured: Baseline through to 72 hours post-start of infusion.

  4. Blood pharmacokinetics (PK) of an intravenous (i.v) dose of NNZ-2566 when administered as a 10-minute infusion immediately followed by a 72-hour infusion.

    Measured: Start of infusion through to 12 hours post infusion.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NNZ-2566 in people with Brain Injuries, run by Neuren Pharmaceuticals Limited at 20 sites 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 9 inclusion and 14 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 5 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites 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?

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?

Reduced incidence, compared to placebo, of adverse events (AEs) and serious adverse events (SAEs) (time frame: AEs to discharged or Day 30 post randomization, whichever occurs first, and SAEs through to 3 months (defined as 12-14 weeks), post randomization.). 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 NCT00805818, 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 5 Feb 2018; AzTrials last refreshed its copy on 8 Nov 2026.
