Study Description

Brief Summary:

The purpose of this study is to test a novel strategy to prevent the clinical problem of secondary autoimmunity following alemtuzumab treatment of multiple sclerosis.

The hypothesis is that autoimmunity after alemtuzumab can be prevented by giving a drug that promotes thymic T cell regeneration (Palifermin, Kepivance®).

Condition or disease	Intervention/treatment	Phase
Multiple Sclerosis	Drug: Palifermin Drug: Alemtuzumab	Phase 1 Phase 2

Detailed Description:

This is a single-centre, double-blinded, randomised controlled trial of palifermin (Kepivance) vs. placebo in the prevention of autoimmunity following alemtuzumab treatment of multiple sclerosis.

The dose of palifermin (kepivance)used in this trial will be informed by a dose-escalation study.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Palifermin (and Alemtuzumab) Palifermin (Kepivance®), at the maximum identified tolerated dose will be administered by intravenous bolus on days -5, -4. -3 prior to, and on days 8, 9 and 10 after each cycle of alemtuzumab, then again on 3 consecutive days at month 1 and month 3 after each cycle of alemtuzumab. Patients will be observed for adverse reactions for at least 1 to 2 hours following each bolus dose. Initial treatment alemtuzumab will be administered as a fixed total dose of 60 mg IV over 5 consecutive days (12mg/day). For re-treatment at Month 12, alemtuzumab will be administered as a fixed total dose of 36mg IV over 3 consecutive days (12mg/day).
