Outcome Measures

Primary Outcomes (1)

  • Percentage of patients with shift from normal (baseline) to abnormal in ECG parameters.

    To determine the shift from normal to abnormal ECG parameters.

    From Day 1 (V3-t1 after investigational drug administration) to Day 15 (V4)

Secondary Outcomes (12)

  • Describe the Ganglion Cell and Inner Plexiform Layer (GCIPL) thickness, absolute and relative change from baseline (of the affected eye) to each time point (t5, M1, M3, M6)

    Up to 6 months

  • Describe the Retinal Nerve Fiber Layer (RNFL) thickness, absolute and relative change from baseline (of the affected eye) to each time point (t5, M1, M3, M6).

    Up to 6 months

  • To describe the visual function on the 2.5% ETDRS Low Contrast Letter Acuity (LCVA) chart change from baseline (of the affected eye) to each time point (D15, M1, M3, M6)

    Up to 6 months

  • To describe the visual function on the 2.5% ETDRS High Contrast Letter Acuity (HCVA) chart change from baseline (of the affected eye) to each time point (D15, M1, M3, M6)

    Up to 6 months

  • To describe the visual function on the Humphrey visual fields evaluations change from baseline (of the affected eye) to each time point (M1, M3, M6)

    Up to 6 months

  • +7 more secondary outcomes

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Diagnosed with a unilateral optic neuritis
  • Onset of visual loss symptoms in the last 12 days before randomization

You may not qualify if:

  • Optic neuropathy of non-demyelinating origin
  • Known Neuromyelitis optica with autoantibodies against aquaporin-4 (AQP4-Abs)
  • Patients with widespread and symmetric white matter alterations in the screening MRI suggestive of other demyelinating disorders (e.g. metabolic disorders, mitochondrial disorders)
  • Active, chronic disease (or stable but treated with immune therapy) of the immune system other than Multiple Sclerosis (MS) or Myelin Oligodendrocyte Glycoprotein Antibody associated Disorder (MOGAD)(e.g. Sjögren's disease, systemic lupus erythematosus) or with a known immunodeficiency syndrome (AIDS, hereditary immune deficiency, drug induced immune deficiency)
  • An alternative cause of visual loss (e.g. compressive or infiltrative lesion of the optic nerve, infections, genetic forms of visual loss.
  • Known diabetic retinopathy
  • Known glaucoma
  • Female patients of child-bearing potential who are unwilling to use an effective contraception while enrolled on study and for the duration of the study.
  • Male patients not willing to use contraception (abstinence, condom etc..) while enrolled in the study and receiving the experimental drug, and for at least 2 days after the last experimental drug administration.
  • Breastfeeding or pregnant women
