‘OrphanOrphan’’ Drugs in CanadaDrugs in Canada

International Orphan Drug Policies

Incentives to drug companies include:– Market exclusivity – Reduction of licensing fees– Assistance with marketing applications– Direct access to centralized procedure for

marketing authorization– Provision of specific research grants (US)

In Canada, no specific ‘Orphan Drug’ policy exists

Special value s/b applied for health gains in rare diseases

Is society willing to pay more for gains in rare than common severe diseases?

No other options

Ensure access when no other treatment exists

Should biologic modification be preferred over health gain?

Small population

Change the rules of ‘burden of proof’

Don’t stop short of best possible evidence!

Different forms of evidence

Registries to determine post-market effectiveness

Registries to determine natural history prior to drug intervention

Budget impact

Equity Rare diseases have same right to treatment as common
