The data presented for years 5, 10, 14, and 20 were obtained from different publications based on the same longitudinal study.
The exact relationship between MRI findings and the clinical status of the patient is unknown.

Alemtuzumab summary of safety
Well-characterized safety and tolerability profile across alemtuzumab
clinical development program1-3
– Most common adverse events were mild/moderate infusion reactions,
which were manageable with appropriate pre-medication and/or treatment,
and patient education1-3
– Low rates of serious infection, consistent with relative sparing of both
innate immune cells and specific lymphocyte subpopulations1,2
– Autoimmune adverse events, including thyroid-related events, ITP, and
nephropathies, were detected with safety monitoring program and
generally responded to conventional therapy1-3
Incorporation of proactive risk-minimization procedures into clinical
trials allowed for early detection and management of identified risks1-3
– Clinical trial experience has informed the Risk Mitigation Plan for
alemtuzumab in the EU

Maintenance vs. Induction
Maintenance therapies
• Continuous treatment
• Low to very high efficacy
• Reversible
• Perceived to be lower risk
• Examples • Laquinimod, GA, IFN-beta, teriflunomide, BG12,
fingolimod, natalizumab, daclizumab
• Breakthrough disease • Suboptimal or failure to respond
• NEDA reliable metric for efficacy
• Rebound activity • Highly likely
• Can be life threatening
• Pregnancy • Contra-indicated
• No potential for a cure • Rebound
• SPMS & progressive brain atrophy
Induction therapies
• Short-courses or pulsed therapy
• Very high efficacy
• Irreversible
• Perceived to be higher risk
• Examples • Mitoxantrone, cladribine, alemtuzumab, anti-
CD20 (?), BMT
• Breakthrough disease • Marker for retreatment
• NEDA unreliable to assess efficacy
• Rebound activity • Less likely
• Unlikely to be life-threatening
• Pregnancy • Strategy of choice
• Potentially curative • 15-20 year experiment
• BMT, alemtuzumab, cladribine

Conclusions • MS is a bad disease
• Mortality, disability, unemployment, divorce, cognitive impairment, etc.
• Early highly-effective treatment is the only realistic option of offering a cure
• Now an established treatment option, which has become safer
• NEDA, T2T and DAF are entering the neurology lexicon
• Zero tolerance or ZeTo
• We need an acceptable working definition of an MS cure
• NEDA x 15 years?
• Induction therapies (alemtuzumab, cladribine)
• Improved risk mitigation tools
• Is it fair to make MSers wait 20 years for the outcome of an ongoing experiment?
• Alemtuzumab, BMT, natalizumab, cladribine extension studies
