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). (Octagon)
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 GA 20mg SC once daily reduces the amount of axonal loss in the optic nerve (measured by RFNL thickness) after a first event of AON compared to placebo patients and to generate data supporting the potential neuroprotective effect of GA in a human in vivo model of axonal loss..

Inclusion Criteria:

  • Age: 18 - 45 years
  • Isolated, unilateral, first AON event consistent with inflammatory demyelinization, not explained by other etiologies. Onset of AON is defined by the presentation of visual disturbances.
  • Able to provide written informed consent prior to enrollment
  • Willing and able to comply with the protocol requirements for the duration of the study
  • For women of child bearing potential:a negative urine pregnancy test o willing to practice an acceptable method of birth control • Willing to receive a steroidal regimen

Exclusion Criteria:

  • A diagnosis of clinically definite MS (CDMS)
  • 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
  • Known ocular or neurological conditions or abnormalities other than refractive error that impair visual function
  • Retrogeniculate visual loss
  • Refractive error of greater than +6 or -6 diopters
  • Neuromyelitis Optica (Devic's disease)
  • Systemic diseases that cause inflammatory optic neuropathy, including but not limited to Sarcoidosis, SLE, Wegener's Granulomatosis, Syphilis, HIV
  • Known ocular conditions that preclude dilation
  • Any condition that may interfere with performance of 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, 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 subject's ability to give informed consent or to complete the study procedures
  • Use of an investigational drug within 30 days prior to randomization
