Study of NNZ-2566 in Patients With Traumatic Brain Injury Under EFIC (INTREPID2566)

February 1, 2018 updated by: Neuren Pharmaceuticals Limited

A Randomized, Double-Blind, Placebo-Controlled, Study of NNZ-2566 in Patients With Traumatic Brain Injury (TBI) Conducted Under an Exception From Informed Consent (EFIC)

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years to 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Non-penetrating TBI.
  • Age 16-75 years.
  • Admission to hospital.
  • Post resuscitation GCS 4-12.
  • Have at least one reactive pupil.
  • Able to receive investigational product within 8 hours of injury.
  • Hemodynamically stable after resuscitation (systolic blood pressure (SBP) >100 mm Hg).
  • Able to read and write English and have sufficient motor dexterity prior to injury to undertake the neuropsychological and activities of daily living (ADL) testing, in the opinion of the investigator, at 1 month (defined as 4-6 weeks) and 3 months (defined as 12-14 weeks) post injury.

Exclusion Criteria:

  • Penetrating brain injury.
  • Spinal cord injury.
  • Presence or known history of prior cerebral injury requiring hospitalization that would, in the opinion of the Investigator, interfere with or bias the assessment of efficacy.
  • Non-traumatic brain injury.
  • Known history of any medical or psychiatric disorder, or any severe concomitant disease that would, in the opinion of the Investigator, interfere with or bias the assessment of efficacy.
  • Significant non-central nervous system (CNS) injuries sustained at the time of the TBI would, in the opinion of the Investigator, interfere with or bias the assessment of efficacy.
  • Weight >150 kg.
  • Participation in another clinical trial within the previous 4 weeks.
  • Clinical state requiring greater than 6 L blood, colloid or crystalloid fluid resuscitation prior to randomization.
  • Pregnant or nursing mothers. Women of child-bearing potential must have a negative urine or blood test prior to randomization.
  • Prior enrollment in this study.

  • QTc Exclusions. The study will use the exclusion criteria as defined in ICH Guideline E14 to exclude patients with a risk of QT/QTc prolongation, as follows:

    • A marked baseline prolongation of corrected QT/QTc interval >450 ms.
    • History of risk factors for torsade de pointes (e.g. heart failure, hypokalemia (serum potassium at screening <3.0 mmol/L)or family history of long QT syndrome).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
