Data from a post-marketing, prospective, observational study in 285 RRMS patients who failed treatment with IFNβ or GA therapy. After failure of

IFNβ or GA therapy patients were switched to either natalizumab (n=106) or IFNβ/GA (n=161); EDSS=Expanded Disability Status Scale;

Natalizumab (TOP) Reduces Risk of Relapse

Compared to IFN and GA ( )

• Natalizumab treatment in TOP was associated with a significant reduction in risk of relapse, compared

with a prospective outcome registry of RRMS patients experiencing at least one relapse on treatment

IFN-GA (MS-COMET).

• In unmatched, unadjusted sample (left panel), risk of relapse was 1.68-fold (95% CI, 1.10–2.19-fold)

greater among MSCOMET compared to TOP MS patients despite a higher disease activity/severity

profile in the TOP cohort at baseline.

• In propensity matched sample (right panel), relapse risk in MSCOMET patients was increased 2.73-fold

(95% CI, 2.10–3.55-fold).

Registries and Independent Studies and AFFIRM:

% Disease Activity Free on Natalizumab

Over 90% of AFFIRM patients were treatment naïve, and the remainder had been on a previous therapy for no more than 6

months, but not treated in the 6 months prior to enrolment. In contrast, approx 90% of patients in registries and independent

studies were switched to natalizumab after experiencing disease activity on a prior therapy.

*Relapse-free (freedom from progression not reported); EDSS worsening not determined in this analysis.

Variables Associated with Overall Freedom from Disease Activity (No Clinical or MRI Activity) over 2 Years in a Multivariate Logistic Regression Analysis

AFFIRM

Natalizumab-treated patients with fewer relapses, fewer MRI lesions, and lower EDSS scores at therapy initiation and who did not develop persistent anti-natalizumab antibodies were more likely to achieve freedom from disease activity over the course of the 2-year AFFIRM study.

Real-life

Stepwise logistic regression analysis showing the predictive variables for having a “full” response to natalizumab (i.e. no clinical and MRI activity) during a 24-month follow-up period.

Natalizumab appears to be more prone to induce a clinical and MRI remission of MS if started in patients with less aggressive disease (i.e. few relapses and mild disability)

PML Risk

≤0.07/1000*

Data beyond 4 years of treatment are limited. *Based on natalizumab exposure and 285 confirmed PML cases as of September 5, 2012. Prior IS data in overall natalizumab-treated patients based

on proportion of patients with IS use prior to natalizumab therapy in TYGRIS as of May 2011; and prior IS data in PML patients as of September 5,

2012. The analysis assumes that 55% of natalizumab-treated MS patients were anti-JCV antibody positive and that all PML patients test positive for

anti-JCV antibodies prior to the onset and diagnosis of PML. The estimate of PML incidence in anti-JCV antibody negative patients is based on the

assumption that all patients received at least 1 dose of natalizumab . Assuming that all patients received at least 18 doses of natalizumab , the estimate

of PML incidence in anti-JCV antibody negative patients was generally consistent (0.1/1000; 95% CI 0.00–0.62).

Page 40: Active disease giovannoni berlin 4 5 may 2013

• Patients and physicians should be equal partners in managing

MS

– Important for physicians to convey risks of MS and MS

therapy, but allow patients to make the ultimate decision

– Physicians should not project own perception of treatment

risks on patients

– This partnership may improve the long-term outcome of

patients with MS
