Primary Purpose: Treatment
Official Title: A Multinational, Multicenter, Randomized, Parallel Group, Double Blind, Placebo Controlled Study Performed in Subjects With Relapsing-Remitting Multiple Sclerosis to Assess the Efficacy, Safety and Tolerability of Glatiramer Acetate 20mg/0.5ml New Formulation Administered Daily by Subcutaneous Injection

Primary Outcome Measures:
  • The Annualized Relapse Rate During the Placebo Controlled Period [ Time Frame: Day 1 up to Month 12 ] [ Designated as safety issue: No ]
    The total number of confirmed relapses during the placebo-controlled phase is divided by the sum of the number of days on study in the placebo-controlled phase and then multiplied by the number of days in the year to calculate the annualized relapse rate.

Secondary Outcome Measures:
  • The Cumulative Number of New or Enlarging T2 Lesions Measured at Months 6 and 12 (End of Placebo Controlled Period) [ Time Frame: Day 1 up to Month 12 ] [ Designated as safety issue: No ]
    Inflammatory disease activity was assessed by magnetic resonance imaging (MRI) measurement of the number of new or newly enlarged T2 lesions.

  • The Cumulative Number of Gadolinium-enhancing Lesions on T1-weighted Images Measured at Months 6 and 12 (End of Placebo Controlled Period) [ Time Frame: Day 1 up to Month 12 ] [ Designated as safety issue: No ]
    Inflammatory disease activity was assessed by magnetic resonance imaging (MRI) measurement of the number of gadolinium-enhanced T1 lesions.

  • Percent Change From Baseline to Month 12 (End of Placebo Controlled Period) in Brain Volume [ Time Frame: Day 1 up to Month 12 ] [ Designated as safety issue: No ]
    Brain atrophy was defined by the percent brain volume change from baseline to Month 12

Enrollment: 178
Study Start Date: March 2012
Study Completion Date: November 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Glatiramer Acetate
Glatiramer acetate (GA) 20 mg/0.5 ml solution in prefilled syringe for subcutaneous injection once daily.

Glatiramer acetate 20mg in 0.5ml for subcutaneous injection in a pre-filled syringe (PFS) is administered daily. Each PFS also contains 20mg mannitol dissolved in water for injection.
Other Name: Copaxone®
Placebo Comparator: Placebo
Placebo solution in prefilled syringe for subcutaneous injection once daily.
Drug: Placebo
Matching placebo injection; 20 mg mannitol dissolved in 0.5 mL water for subcutaneous injection in a PFS is administered daily.

Detailed Description:

Approximately 1400 participants were planned for this study, however only 178 were enrolled prior to early termination.


Ages Eligible for Study:   18 Years to 55 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Subjects must meet all inclusion criteria in order to be eligible for the study:

  • Subjects must have a confirmed and documented multiple sclerosis (MS) diagnosis as defined by the 2010 Revised McDonald criteria [Ann Neurol 2011: 69:292-302], with a relapsing-remitting disease course.
  • Subjects must be ambulatory with a Kurtzke's Expanded Disability Status Scale (EDSS) score of 0-5.5 in both screening and baseline visits.
  • Subjects must be in a relapse-free, stable neurological condition and free of corticosteroid treatment [intravenous (IV), intramuscular (IM) and/or by mouth (PO)] or ACTH (adrenocorticotropic hormone) 30 days prior to screening (Month-1) and between screening and baseline (Month 0) visits.
  • Subjects must have experienced one of the following:
  • At least one documented relapse in the 12 months prior to screening,
  • At least two documented relapses in the 24 months prior to screening,
  • One documented relapse between 12 and 24 months prior to screening with at least one documented T1-Gd enhancing lesion in a magnetic resonance imaging (MRI) performed within 12 months prior to screening.
  • Subjects must be between 18 and 55 years of age, inclusive.
  • Women of child-bearing potential must practice an acceptable method of birth control [acceptable methods of birth control in this study include: surgical sterilization, intrauterine devices, oral contraceptive, contraceptive patch, long-acting injectable contraceptive, partner's vasectomy or a double-barrier method (condom or diaphragm with spermicide)].
  • Subjects must be able to sign and date a written informed consent prior to entering the study.
  • Subjects must be willing and able to comply with the protocol requirements for the duration of the study.

Exclusion Criteria:

Any of the following conditions will exclude the subject from entering the study:

  • Subjects with progressive forms of MS.
  • Use of experimental or investigational drugs, and/or participation in drug clinical studies within the 6 months prior to screening.
  • Use of immunosuppressive agents (including Mitoxantrone and Fingolimod) or cytotoxic agents within 6 months prior to the screening visit.
  • Use of natalizumab (Tysabri®) or any other monoclonal antibodies within 2 years prior to screening.
  • Use of cladribine within 2 years prior to screening.
  • Previous treatment with immunomodulators [including IFNβ 1a and 1b, and IV Immunoglobulin (IVIg)] within 2 months prior to screening.
  • Previous use of glatiramer acetate (GA) or any other glatiramoid.
  • Chronic (more than 30 consecutive days) systemic (IV, PO or IM) corticosteroid treatment within 6 months prior to screening visit.
  • Previous total body irradiation or total lymphoid irradiation.
  • Previous stem-cell treatment, autologous bone marrow transplantation or allogenic bone marrow transplantation.
  • Pregnancy or breastfeeding.
  • Subjects with a clinically significant or unstable medical or surgical condition that would preclude safe and complete study participation, as determined by medical history, physical exams, ECG, abnormal laboratory tests and chest X-ray. Such conditions may include hepatic, renal or metabolic diseases, systemic disease, acute infection, current malignancy or recent history (5 years) of malignancy, major psychiatric disorder, history of drug and/or alcohol abuse and allergies that could be detrimental according to the investigator's judgment.
  • A known history of sensitivity to Gadolinium.
  • Glomerular filtration rate (GFR) ≤ 60 mL/minute at the screening visit
  • Inability to successfully undergo MRI scanning.
  • A known drug hypersensitivity to Mannitol.
  • Subjects who underwent endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI).
