NEDA would be a subgroup of the true and false responders True responders • No or reduced activity due to treatment effect Non- responders False • Continued disease activity despite responders treatment • No or reduced activity due to natural history How Predictable is NEDA? Does NEDA early on predict disability progression?
Large actively treated cohort (n= 517) followed for 10 years at UCSF
17.9% of patients met NEDA criteria at year 2 NEDA at year 2 was NOT associated with significant EDSS progression after 10 years (trending actually to worsening EDSS!) No identified significant effect of new or enlarging T2 lesions at year 2 on disability progression at 10 years ¡ As measured by EDSS, T25FW, 9HPT, PASAT-3 ¡ Increase in EDSS by year 2 paradoxically associated with lower risk of subsequent worsening

Induction?
Escalation?
DISEASE PROGRESSION Rationale for Starting MS Therapy With a 1st Line Agent (Escalation Approach)
Rationale • Long-term and real-life clinical and safety data lacking for many DMT • Patients may still respond well to 1st line agents • MS is a disease of years and decades • ‘Induction’ remains a concept but may be required for certain patients • Target populations warranting early and aggressive treatment are yet to be well defined The principle • “Start safe and effective, reassess early, and escalate if necessary”

Disease causing immune cells Rationale for Starting MS Therapy With a ≥ 2nd Line Agent (Induction Approach)
Reserved for patients with aggressive disease onset Rationale • Start with an agent with a rapid onset of action • Ideal treatment has the following goals ÷ Damage control to prevent or limit further damage ÷ To protect injured axons and neurons from further injury ÷ To encourage repair of reversible damaged tissue • Once a patient enters the progressive phase of MS, it may be too late to attain any stated goals of treatment
