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.

Study Start Date: July 1995
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 hours.

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.
