Study of Tcelna (Imilecleucel-T) in Secondary Progressive Multiple Sclerosis
- Conditions
- Autoimmune Diseases of the Nervous SystemMultiple SclerosisSecondary Progressive Multiple SclerosisDisease ProgressionBrain Atrophy
- Interventions
- Biological: PlaceboBiological: Tcelna
- Registration Number
- NCT01684761
- Lead Sponsor
- Opexa Therapeutics, Inc.
- Brief Summary
The purpose of this study is to determine whether Tcelna (imilecleucel-T, autologous T-Cell Immunotherapy) is effective in the treatment of secondary progressive multiple sclerosis (SPMS).
- Detailed Description
Subjects whose myelin reactive T-cell can be identified by EPA will are randomized and provide blood to manufacture Tcelna. Approximately 5 weeks after receipt of the subject's whole blood procurement, the subjects will receive either Tcelna or placebo and will complete baseline assessments and will receive study treatments at Weeks 0, 4, 8, 12, and 24 (Visits 3-7), totaling 5 doses in year one.
Approximately one month prior to the Week 52 visit a second blood procurement will be performed and the subject will receive the second series of treatments as received in the first year study schedule. Subjects will be evaluated for changes in disability and cognitive function every 3 months, and radiographic changes annually.

Group Intervention Description Placebo Placebo Tcelna inactive ingredients (without cells) totaling 2 ml per dose. Administered subcutaneously with same two year treatment regimen as experimental treatment arm. Tcelna Tcelna 30-45 x 10E6 total cells in 2 ml. Subjects receive two annual courses of 5 subcutaneous doses each year (at 0, 4, 8, 12 and 24 weeks).
