By the Numbers: Rare Diseases and Conditions
July 16, 2021
A rare disease is, by definition, uncommon. Taken collectively, however, rare diseases touch millions of Canadians—which means that timely and equitable access to the right treatments can have an enormous impact on Canadian lives.
Rare disease realities
7,000: the approximate number of rare diseases identified in the world to date.1
80%: the proportion of rare diseases that have a genetic origin.1
One in 12: The estimated proportion of Canadians who live with a rare disease.1
50%: Proportion of rare diseases that begin in early childhood and involve progressive, life-threatening deterioration.1 In fact, rare diseases account for 30-40% of neonatal deaths.2
5%: Approximate percentage of rare diseases with a currently available treatment.2
7: Number of curative therapies for rare diseases and conditions, 3 of which 3 are currently available in Canada.4
The rare drug market
40%: percentage of pipeline drugs in pre-registration phase that target rare diseases.5
300: Approximate number of cell and gene therapies in development, collectively targeting more than 100 diseases.6
32%: Growth of the Canadian market for expensive drugs for rare diseases (EDRD) from 2012 to 2019—more than 6 times the growth rate for all prescription drugs in Canada.7
9.4%: Share of total drug-spend in Canada devoted to expensive drugs for rare diseases (EDRD), including oncology and non-oncology medications.7
$2.1M: Approximate cost of Zolgensma, a medication for spinal muscular atrophy, approved in Canada in 2020 and dubbed the “most expensive treatment in the world.”8,4
$200,000: minimum annual cost of 76% of all EDRD approved in Canada, as of 2019.9
Access status and setbacks
50%: Approximate proportion of EU-approved drugs for orphan diseases (neglected rare diseases) that end up approved in Canada.10
18-24 months: Delay between Health Canada approval and public reimbursement of orphan-disease drugs.10
99%: Price discount that would be required if applying new Patented Medicine Prices Review Board (PMPRB) regulations to two new cystic fibrosis drugs.11,12
26: Number of European Union member countries (out of 28) who have their own framework for reviewing rare disease drugs.13
$500M: Funds earmarked in the Canadian government’s 2019 federal budget to a program for rare diseases.14
0: Frameworks for rare diseases in Canada. This may change with the government’s recently released consultation document on “Building a National Strategy for High-Cost Drugs for Rare Diseases.”9
