Trial summary

The main objective of the study is to determine whether glatiramer acetate 20 mg once daily reduces the amount of axonal loss in the optic nerve after a first event of acute optic neuritis compared to placebo patients and to generate data supporting the potential neuroprotective effect of glatiramer acetate in a human… Read more about this study

  • No healthy volunteers
  • Adult

Who may be able to join

  • Age: 18 - 45 years
  • Isolated, unilateral, first acute optic neuritis (AON) event consistent with inflammatory demyelinization, not explained by other etiologies. Onset of AON is defined by the presentation of visual disturbances.

Who cannot join

  • A diagnosis of clinically definite multiple sclerosis (MS) (Clinically Definite Multiple Sclerosis)
  • Current use of any approved disease modifying agents for treatment of MS
  • Prior clinical episode of optic neuritis in either eye
  • Bilateral AON
  • Inability to undergo study evaluations in both eyes

Show all 20Show fewer
  • Retrogeniculate visual loss
  • Refractive error of greater than +6 or -6 diopters

  • Systemic diseases that cause inflammatory optic neuropathy, including but not limited to Sarcoidosis, Systemic lupus erythematosus (SLE), Wegener's Granulomatosis, Syphilis, human immunodeficiency virus (HIV)
  • Known ocular conditions that preclude dilation
  • Any condition that may interfere with performance of Optical Coherence Tomography (OCT): corneal, lens or fundoscopic abnormality, a co-morbid ocular condition not related to optic neuritis as detected on the OCT reading
  • Any condition that precludes administration of Glatiramer Acetate, such as a known history of sensitivity to mannitol
  • Diabetes Mellitus Types I or II
  • Gastric bypass surgery
  • Current use of chemotherapy or radiotherapy
  • Treatments that may cause visual loss such as plaquenil, anti-tubercular agents, interferon (IFN)-alpha therapy, monoclonal antibodies Cardiac medications that may affect visual evaluations such as digitalis, amiodarone, quinine
  • Ongoing treatment with steroids (for longer than 10 days) within the last 3 months
  • Significant or unstable medical, systemic, psychiatric or logistical condition that affects the patient's ability to give informed consent or to complete the study procedures
  • Use of an investigational drug within 30 days prior to randomization

About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Multicenter Study of the Effects of Glatiramer Acetate (GA) on the Retinal Nerve Fiber Layer (RNFL) and Visual Function in Patients With a First Episode of Acute Optic Neuritis (AON)

The main objective of the study is to determine whether glatiramer acetate 20 mg once daily reduces the amount of axonal loss in the optic nerve after a first event of acute optic neuritis compared to placebo patients and to generate data supporting the potential neuroprotective effect of glatiramer acetate in a human in vivo model of axonal loss.

What is being measured

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

  1. Retinal Nerve Fiber Layer Thickness at Baseline and Month 6

    Axonal loss in the optic nerve (due to optic neuritis) was assessed by measuring retinal nerve fiber thickness of the affected eye using optical coherence tomography (OCT) at Baseline and Month 6.

    Measured: Baseline and Month 6

Secondary outcomes (1)
  1. To Evaluate Changes on Additional OCT Parameters and Other Visual Function and Clinical Parameters.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Glatiramer Acetate in people with Optic Neuritis, run by Teva Branded Pharmaceutical Products R&D, Inc..

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: finished, as of the sponsor's last update on 6 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 23 Sep 2013). 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?

Retinal Nerve Fiber Layer Thickness at Baseline and Month 6 (time frame: Baseline and Month 6). 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 6 Feb 2018; AzTrials last refreshed its copy on 31 Oct 2026.
