Why switch?

Page 5: Switching to orals therapies

Why would you switch from an injectable?

1. Stable on treatment: no evident disease activity, no concerns

2. Stable on treatment: poor tolerance

3. Stable on treatment: poor adherence

4. Stable on treatment: want to fall pregnant

5. Breakthrough disease: suboptimal efficacy

No

But, why only an oral?

Quality of life and disability

MS is one of the most common causes of neurological disability in young adults2

Natural history studies indicate that it takes a median time of 8, 20 and 30 years to reach the irreversible disability

levels of EDSS 4, 6 and 7, respectively3

Up to 75% increased annualized divorce rate4

Life expectancy is reduced by 5-10 years5

7.5x greater than suicide rate than the general population6

2 out of 3 patients with RRMS were unemployed due to the disease7

Why?

Adherence

Page 30: Switching to orals therapies

• In MS, patients with long gaps in treatment are at greater risk of relapse than more adherent patients1

• Lower adherence to MS therapy is associated with a higher risk of relapse2

Treatment gaps and poor adherence are associated with increased relapse rates

Adherence is one of the keys to optimizing outcomes

Psychological factors – forgetfulness and complacency

– impact adherence

Observational GAP study

Devonshire V et al. Eur J Neurol 2011;18:69-77 Patients could have reported more than one reason for non-adherence. When counting injection-related reasons for non-adherence, each patient was counted only once. GAP, Global Adherence Project

Do really think a tablet is going to improve poor adherence?

Why?

Pregnancy

Page 34: Switching to orals therapies

Considerations for Women of Childbearing Potential

Interferon β • In monkeys, increased rate of abortion. No malformations in

surviving animals

• Initiation of treatment is contraindicated during pregnancy

Glatiramer acetate

• Animal studies are insufficient with respect to effects on pregnancy;

embryonal/foetal development, parturition, and postnatal

development

• Contraindicated during pregnancy / registers indicate it is safe

Natalizumab

• Studies in guinea pigs and monkeys showed no evidence of

teratogenic effects or effects on growth of offspring

• Should not be used during pregnancy unless the clinical condition of

the woman requires treatment with natalizumab

Fingolimod

• Animal studies have shown reproductive toxicity, including foetal loss

and teratogenicity

• While on treatment, women should not become pregnant; if

pregnancy occurs, discontinuation of fingolimod is recommended

CO-CZ-0056b

Data from summary of product of characteristics (SmPC) for each therapy.

Page 35: Switching to orals therapies

Considerations for Women of Child-bearing Potential

Teriflunomide

• Embryotoxic and teratogenic in rats and rabbits at doses in the

human therapeutic range

• Contraindicated in pregnancy

• Patient advised to contact physician if pregnancy is suspected;

institution of accelerated elimination may decrease risk to foetus

Alemtuzumab

• Dosing mice for 5 days during gestation resulted in significant

increases in dead or resorbed conceptuses and reduction in viable

foetuses

• Placental transfer and potential pharmacologic activity observed

• Contraception advised during treatment and for 4 months following

• Should be administered during pregnancy only if the potential benefit

justifies the potential risk to the foetus

• Thyroid disease poses special risks in women who are pregnant

(potential miscarriage, foetal effects such as mental retardation and

dwarfism, transient neonatal Graves’ disease)

Dimethyl fumarate • No malformations have been observed at any dose in rats or rabbits

• Should be used during pregnancy only if clearly needed and if the

potential benefit justifies the potential risk to the foetus

Conclusions

• MS is a bad disease • Mortality, disability, unemployment, divorce, suicide cognitive

impairment, etc.

• New treatment paradigm • Early effective treatment

• Therapeutic ladder; early treatment with rapid escalation

• Maintenance vs. induction therapy • Adherence and pregnancy major discriminators

• Improved risk mitigation tools

• Treat-2-target of NEDA

• Prevent end-organ damage (brain atrophy & CSF NF levels)

• Sustained improvement (treat early)

• Protect reserve capacity (healthy ageing)

• Long-term remission

• Is there any reason why you would limit yourself to an oral therapy?

Page 39: Switching to orals therapies

Why would you switch from an injectable?

1. Stable on treatment: no evident disease activity, no concerns

2. Stable on treatment: poor tolerance

3. Stable on treatment: poor adherence

4. Stable on treatment: want to fall pregnant

5. Breakthrough disease: suboptimal efficacy
