Study Details

Study Description

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).

Condition or Disease Intervention/Treatment Phase
  • Biological: Tcelna
  • Biological: Placebo
Phase 2

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 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).

Biological: Tcelna
Autologous pool of myelin reactive T-cells (MRTC) expanded ex vivo with immunodominant epitopes selected from the three myelin antigens, MBP, PLP and MOG on a per subject basis. Attenuated by irradiation to prevent further proliferation before releasing product for administration.

Placebo Comparator: Placebo

Tcelna inactive ingredients (without cells) totaling 2 ml per dose. Administered subcutaneously with same two year treatment regimen as experimental treatment arm.

Biological: Placebo
2 ml of Tcelna excipients, prepared daily as individual doses and irradiated before releasing product for administration.

Outcome Measures

Primary Outcome Measures

  1. Brain Atrophy [2 Years]

    The percentage of brain volume change (atrophy) as measured on 24 month MRIs calculated by the central MRI facility.

Secondary Outcome Measures

  1. Disease Progression [2 Years]

    The percentage of subjects with sustained progression with definitions of sustained effect at 3 months and 6 months.

  • Previous treatment with any other MS investigational drug 1 year prior to screening

  • All non-MS investigational drugs must have a minimum washout of 30 days prior to screening or 5 half-lives, whatever is the longest period of time.

  • HIV or hepatitis infection

  • History of cancer

  • Any other significant medical condition that, in the opinion of the investigator, could cause CNS tissue damage or limit its repair.
