A Maintenance Extension of Phase I Pilot Study of Chimeric Anti-CD4 Antibody M-T412 in Patients With Multiple Sclerosis

Brief Title

A Maintenance Extension of Phase I Pilot Study of Chimeric Anti-CD4 Antibody M-T412 in Patients With Multiple Sclerosis

Brief Summary

      OBJECTIVES: I. Evaluate the safety and immunogenicity of single and multiple doses of M-T412,
      a chimeric murine-human anti-CD4 monoclonal antibody, in patients with multiple sclerosis.

      II. Evaluate the pharmacokinetics of M-T412. III. Obtain preliminary data on the clinical
      response to M-T412.

Detailed Description

      PROTOCOL OUTLINE: This is an open label, dose escalating study. Escalating doses of M-T412
      are administered to cohorts of 5 patients each receiving a single dose intravenously over 2

      Patients who complete the single dose assessment of M-T412 may receive up to 3 additional
      single doses of M-T412 IV over 2 hours, with each repeated dose given at least 1 month apart.

      Then, patients receive one dose level of M-T412 IV over 2 hours at 3 month intervals over a
      period of 12 months for a total of 5 doses. Once recovery of CD4 cells is obtained, the next
      scheduled infusion of M-T412 begins. Patients are omitted from study if CD4 cells remain
      attenuated following 2 scheduled infusion sessions.

      Patients are followed at 3, 6, 12, and 24 months after the first infusion.
