Primary Outcome Measures:
  • Evaluate Changes in Number of Combined Unique Active Lesions on Brain Magnetic Resonance Imaging (MRI) [ Time Frame: Annually ]
    This extension study was discontinued due to financial constraints of the company. Of the 38 patients dosed, 32 did not complete all 5 doses. Of the 6 patients that completed the 5 doses, 5 patients did not have a Wk 52 MRI and therefore, no efficacy results are summarized as there is no comparison data.

Secondary Outcome Measures:
  • Evaluate Changes in Rate and Severity of Multiple Sclerosis (MS) Progression [ Time Frame: Annually ]
  • Evaluate Changes in Annualized Relapse Rate [ Time Frame: Annually ]

Enrollment: 116
Study Start Date: November 2007
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tovaxin, open-label
Tovaxin; 30-45 million autologous myelin reactive T cells
Biological: Tovaxin
2 mL subcutaneous injections administered by a healthcare provider at weeks 0, 4, 8, 12, and 24 every year as required.
Other Names:
  • Autologous TCV
  • T Cell Vaccine

Detailed Description:
The subjects with positive myelin-reactive T cells (MRTC) in their blood during the previous TERMS study will immediately be eligible for Tovaxin production and treatment in this open label extension study. The MRTC negative subjects will be monitored quarterly for safety, MRTC reactivity, paraclinical and clinical effect. Subjects who become MRTC positive during the monitoring phase will then be eligible for Tovaxin production and treatment in this study.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects who completed the TERMS study and received at least 1 study treatment injection
  • Signed and dated statement of informed consent

Exclusion Criteria:

  • Pregnancy or breastfeeding
  • Experienced a serious adverse drug reaction with confirmatory relationship to Tovaxin in the TERMS study.
  • Withdrew from TERMS study and did not continue participating in the remaining 52-week core TERMS study assessments.
  • Non-compliant with TERMS study.
  • Diagnosis of progressive-relapsing, secondary progressive or primary progressive Multiple Sclerosis (MS) while enrolled in the TERMS study.
  • Medical, psychiatric or other conditions that compromise the subject's ability to give informed consent, to understand the patient information, to comply with the study protocol, or to complete the study.
  • Any significant change in the subject's medical condition after enrollment in the TERMS study which would have lead to his/her exclusion from participation in that study.
