The brain health perspective on MS
Slide 7-

The brain health perspective on MS shows that time matters Cognitive impairment has practical implications Disease activity can persist even if symptoms are absent Neurological reserve must be preserved Cognitive impairment predicts physical disability progression
Slide 8-

Disease activity persists: damage occurs throughout the CNS In relapsing MS, the damage to the CNS is no longer considered to consist solely of discrete macroscopic lesions affecting myelin1 Damage is diffuse and ongoing throughout the disease course Damage occurs in the white and grey matter Accelerated brain atrophy proceeds throughout the disease course, and is evident even in people with RIS and CIS2 CIS, clinically isolated syndrome; CNS, central nervous system; RIS, radiologically isolated syndrome 1. Filippi M, Rocca MA, 2005; 2. De Stefano N et al., 2010

Available at: www.msbrainhealth.org This example illustrates how brain atrophy may be accelerated in a person with untreated MS, with disease onset at 25 years of age, compared with a healthy individual
Slide 10-

Disease activity persists: but only 1 in 10 lesions results in a relapse Only 1 in 10 lesions results in a relapse,1,2 but all contribute to loss of neurological reserve Monthly MRI in 7 people with RRMS over 1 year showed that much disease activity is subclinical1 50 new contrast-enhancing lesions were detected (6 patients) Only 5 relapses occurred (3 patients) CNS, central nervous system; MRI, magnetic resonance imaging; RRMS, relapsing–remitting multiple sclerosis 1.

Neurological reserve must be preserved: capacity to retain function is finite Neurological reserve: the brain’s finite capacity to retain function by remodelling itself to compensate for loss of nerve cells and fibres1,2 Neurological reserve may explain why: MS-related brain injury can go undetected during the early phase of the disease MS can be undiagnosed and untreated for a long time 1. Rocca MA et al., 2003; 2. Rocca MA, Filippi M, 2007 Brain volume Neurological reserve Cognitive reserve + =
Slide 12-

Neurological reserve must be preserved: protection against disability progression Preserving brain volume1 and cognitive reserve2 protects against disability progression RCT, randomized controlled trial; RRMS, relapsing–remitting multiple sclerosis 1. Sormani MP et al., 2014; 2. Schwartz CE et al., 2013 Brain volume Meta-analysis of 13 RCTs including more than 13 500 people with RRMS1 Treatment effects on disability progression and brain atrophy were correlated (R2 = 0.48) Treatment effects on disability progression and new/enlarging MRI lesions were correlated (R2 = 0.61) Cognitive reserve Longitudinal study of 859 people with MS2 Patients with high active cognitive reserve had a lower symptom burden than those with low active cognitive reserve, independent of passive cognitive reserve (p < 0.01)
Slide 13-

Cognitive impairment has practical implications Cognitive impairment in early MS is associated with: Decreased quality of life1 Decreased daily functioning2 Decreased employability Unemployment levels among people with MS are higher than those in the general population, even at low levels of physical disability3,4 EDSS, Expanded Disability Status Scale 1. Glanz BI et al., 2010; 2. Rao SM et al., 1991; 3. Kobelt G et al., 2006; 4. Kobelt G et al., 2009 Even if a person with MS is fully mobile most of the time, employability is decreased, suggesting that cognitive impairment plays an important role
Slide 14-

Cognitive impairment predicts disability progression (1/2) Cognitive impairment can be present years before the more obvious clinical symptoms of MS appear1 A case–control study found that school performance was poorer in 75 people who later developed clinical symptoms of MS (84% RRMS; 15% SPMS; 1% PPMS) than in 75 individuals who did not develop MS Cognitive function is predictive of short-term2 and long-term3 clinical disability progression in patients with RRMS PPMS, primary progressive multiple sclerosis; RRMS, relapsing–remitting multiple sclerosis; SPMS, secondary progressive multiple sclerosis 1. Sinay V et al., 2015; 2. Raghupathi K et al., 2015; 3. Moccia M et al., 2015
Slide 15-

Cognitive impairment predicts disability progression (2/2) Short-term clinical disability progression1 1582 people with RRMS treated with placebo were monitored for up to 2 years Baseline cognitive function predicted clinical disability progression, as assessed using: EDSS Multiple Sclerosis Functional Composite Visual Function Test Long-term clinical disability progression2 155 people with RRMS receiving treatment were included in a retrospective longitudinal study After 10 years, compared with those with preserved cognition at diagnosis, people with cognitive impairment at diagnosis were: more than three times as likely to have reached an EDSS score of 4.0 more than twice as likely to have progressed to secondary progressive MS EDSS, Expanded Disability Status Scale; RRMS, relapsing–remitting multiple sclerosis 1. Raghupathi K et al., 2015; 2. Moccia M et al., 2015

Three key recommendations for change
Slide 17-

Three key recommendations for change Maximize lifelong brain health 1. Minimize delays in diagnosis and treatment 2. Monitor disease activity and treat to a target 3. Generate and use robust evidence
Slide 18-

1. Minimize delays in diagnosis and treatment Adopt the latest accepted diagnostic criteria, to diagnose MS as early as possible Promptly refer people with suspected MS to a neurologist with a special interest in MS Speed up diagnosis Speed up treatment initiation
Slide 19-

Refer people with suspected MS to specialists DMT, disease-modifying therapy; HCP, healthcare professional
Slide 20-

Speed up diagnosis A delay of up to 2 years can occur between observation of the first symptom and seeing a neurologist1 There is a relationship between the length of delay in referral to a neurologist with a special interest in MS and the level of disability at the time of the first visit2 1. Fernandez O et al., 2010; 2. Kingwell E et al., 2010 The longer the delay, the greater the initial disability level2
Slide 21-

Adopt the latest accepted diagnostic criteria Poser criteria (1984)1 Required two acute clinical relapses Relied on directly observable events McDonald criteria (2001, revised in 2005 and 2010)2–4 Require at least one clinical relapse Incorporate MRI evidence DMT, disease-modifying therapy; MRI, magnetic resonance imaging 1. Poser CM et al., 1983; 2. McDonald WI et al., 2001; 3. Polman CH et al., 2005; 4. Polman CH et al., 2011; 5. Dalton CM et al., 2002; 6. Tintore M et al., 2003 The number of people whose MS is accurately diagnosed within 1 year of their first relapse more than doubles5 or triples6 using McDonald criteria (2001) rather than Poser criteria Despite widespread adoption of the 2010 criteria,4 some prescribing guidelines require two clinical relapses before initiation of a DMT
Slide 22-

Speed up treatment initiation In people with a diagnosis of CIS, treatment with a DMT increases the time to a second relapse (i.e. progression to RRMS under any diagnostic criteria) and improves MRI outcomes1–3 In people with a diagnosis of CIS4–6 or RRMS,7–9 initiating treatment with a DMT early in the disease course is associated with better long-term outcomes than delaying treatment CIS, clinically isolated syndrome; DMT, disease-modifying therapy; MRI, magnetic resonance imaging; RRMS, relapsing–remitting multiple sclerosis 1. Jacobs LD et al., 2000; 2. Comi G et al., 2001; 3. Kappos L et al., 2006; 4. Comi G et al., 2013; 5. Kinkel RP et al., 2012; 6. Edan G et al., 2015; 7. Johnson KP et al., 2005; 8.

Slide 23-

Overview of key recommendation Therapeutic strategy Early referral and diagnosis Early treatment Goal: maximize lifelong brain health Leads to Minimize delays in the diagnosis of MS and in the time to treatment initiation as these can result in irreversible disability progression
Slide 24-

2. Monitor disease activity and treat to a target DMT, disease-modifying therapy Make the full range of DMTs available and select the most appropriate treatment Share decision-making Encourage adoption of a brain-healthy lifestyle Monitor and assess clinical and subclinical indicators of disease activity Consider switching if treatment response is suboptimal
Slide 25-

Share decision-making Set an explicit treatment target Involve the individual with MS proactively in decision-making Enable people with MS to play a fully informed role in making treatment decisions by explaining: principles and benefits of a brain-healthy lifestyle benefits of early treatment with agents that can modify the disease course likely consequences of inadequate or suboptimal treatment Encourage adherence to DMTs by helping people with MS to feel informed about their disease and its treatment1 and to develop good relationships with their care team2,3 Adherence to DMTs is associated with fewer relapses and lower medical costs3 DMT, disease-modifying therapy 1. de Seze J et al., 2012; 2. Remington G et al., 2013; 3. Bunz TJ et al., 2013
Slide 26-

Adopt a brain-healthy lifestyle A brain-healthy lifestyle involves: Increasing activities that enhance cognitive reserve Increasing cardiovascular fitness Decreasing alcohol intake Decreasing smoking Avoiding a deficiency in vitamin D Optimizing control of comorbidities To reduce their negative effect on the MS disease course To limit the potential for disability unrelated to MS
Slide 27-

Make the full range of DMTs available RWE regarding the long-term effectiveness of established DMTs is mixed Most studies report that a particular class of established DMT can slow (but not prevent) disability progression;1,2 others report no effect on disability progression3 Some newer DMTs have been shown to be more effective at reducing disability progression, relapse rate and/or burden of lesions when compared head-to-head with established DMTs in clinical trials4–9 Others have been compared only with placebo10–11 DMT, disease-modifying therapy; MoA, mode of action; RWE, real-world evidence 1. Trojano M et al., 2009; 2. Trojano M et al., 2007; 3. Shirani A et al., 2012; 4. Rudick RA et al., 2006; 5. Coles AJ et al., 2008; 6. Cohen JA et al., 2010; 7. Cohen JA et al., 2012; 8. Coles AJ et al., 2012; 9. Coles AJ et al., 2012; 10. Polman CH et al., 2006; 11. O’Connor P et al., 2011
Slide 28-

Select the most appropriate treatment Make the full range of DMTs available to people with active relapsing forms of MS, regardless of treatment history, to help to: speed up adoption of the most appropriate treatment optimize effectiveness and safety for each individual Make a shared decision about the DMT that best fits the disease course, values, needs, limitations and lifestyle of each patient DMT, disease-modifying therapy
Slide 29-

Monitor clinical and subclinical indicators Meta-analyses provide strong evidence that treatment effect on disability progression is correlated with treatment effect on: relapses (R2 = 0.71)1 new or active (R2 = 0.71)2 and exclusively active (R2 = 0.81)3 MRI lesions brain atrophy (R2 = 0.48)4 MRI, magnetic resonance imaging 1. Sormani MP et al., 2010; 2. Sormani MP, Bruzzi P, 2013; 3. Sormani MP et al., 2009; 4. Sormani MP et al., 2014
Slide 30-

Disability progression Relapses Unreported relapses Patient-reported outcomes Brain atrophy Neurofilament levels Lesions detectable using standard clinical MRI techniques (white matter) Lesions currently undetectable using standard clinical MRI techniques (white and grey matter) Assess all parameters Include all parameters predictive of future relapses and disability progression in assessments of disease activity Update assessments as the evidence base for novel parameters grows Perform MRI brain scans to monitor lesions and brain volume loss (if possible) at predefined intervals and when necessary MRI, magnetic resonance imaging Candidate parameters Recommended parameters
Slide 31-

Consider switching if treatment response is suboptimal Maintain treatment with a DMT for as long as there would be risk of inflammatory disease activity if there was no treatment Adopt clear management principles to identify treatment failure Consider switching to a different DMT if response is suboptimal DMT, disease-modifying therapy Figure adapted from Giovannoni G. 2014.

3. Generate and use robust evidence DMT, disease-modifying therapy Consult the most robust evidence about DMTs Generate real-world evidence Use long-term real-world evidence to support decision-making
Slide 34-

Generate real-world evidence Proactively collect and record data, using standardized data collection techniques and protocols Use these data to inform daily practice Incorporate these data into national and international registries and databases to generate real-world evidence
Slide 35-

Use long-term real-world evidence Regulatory authorities, HTA bodies and payers make initial decisions about DMTs using data from short-term clinical trials Recent real-world evidence on long-term efficacy and safety of DMTs is needed to provide further support for these decisions DMT, disease-modifying therapy; HTA, health technology assessment; RWE, real-world evidence
Slide 36-

Consult the most robust evidence about DMTs Consult the most robust evidence available about the long-term effectiveness and safety of DMTs and therapeutic strategies Encourage the continuing investigation, development and use of therapeutic strategies that reduce the costs of managing MS, to improve access to treatment DMT, disease-modifying therapy; HTA, health technology assessment; RWE, real-world evidence
