Canada’s Evolving Market for Biosimilars and What It Means for Payers
Introduction
Potential savings from biosimilars are a subject of keen interest internationally, with a particular relevance for Canadians. Given the high use and cost of biologics in Canada, the increased use of biosimilars offers a significant opportunity for cost savings for Canadian payers.
Unlike small molecule medicines, which experience a relatively quick market adjustment after generic entry, most originator biologics in Canada continue to dominate the market after the introduction of a biosimilar. This, in turn, limits the savings for Canadian payers and their potential ability to fund new therapies that enter the market with increasingly high prices.
Recent policy changes to promote biosimilar switching are expected to result in significant cost reductions for relevant classes of biologics in Canada, helping to offset the pressure from new higher-cost medicines in coming years.
This analysis compares the emerging Canadian market for biosimilars with our international counterparts and assesses the impact of the recent biosimilar switching initiatives, highlighting the potential for cost savings in Canada. IQVIA’s MIDAS® Database as of 2020 was used to compare the availability, uptake, and sales of biosimilars in Canada to the Organization for Economic Co-operation and Development (OECD) countries. The market dynamics of biosimilars in Canada in 2020 and 2021 and the potential for cost savings were drawn from IQVIA’s Canadian Drugstore and Hospital Purchases Audit (CDH).

Canada spends more on biologics per capita than almost all other industrialized countries. In 2020, biologics accounted for 33.9% of pharmaceutical sales in Canada, the third-highest share in the OECD and exceeding the median of 27.4%. Canadians spent an average of $262 per person on biologic medicines in the same year, well above the international median of $156. This placed Canada fourth among the OECD countries in terms of per capita sales.

* Countries with limited sales data were excluded from this analysis.

Biosimilar availability and uptake in Canada and other OECD countries
Despite an increase in biosimilar approvals in Canada over recent years, Europe continues to lead with the highest in terms of the number of biosimilar approvals. As of the end of 2020, biosimilars for 14 distinct biologic medicines were approved by Health Canada, compared to 17 by the European Medicines Agency (EMA) and 12 by the US Food and Drug Administration (FDA).
For distinct biologic molecules with biosimilars approved and sold across the OECD, biosimilar uptake in Canada is moderate compared to international markets, particularly for high-selling products. Infliximab, the top-selling biologic and one of the earliest with a biosimilar available in Canada, had a 20% biosimilar share in Canada in 2020, well below the OECD median of 73%. Adalimumab, the second highest-selling biologic medicine, had no recorded biosimilar sales in Canada in 2020 and a median biosimilar uptake of 28% in the OECD.

* In 2018 Adalimumab biosimilar was approved in Canada, with sales starting in February 2021. Therefore, no uptake is captured in the figure.

Biosimilar uptake challenges and current policies
In Canada there are several key factors may influence biosimilar uptake:
- Interchangeability: As in most countries, biosimilars are not interchangeable with the originator biologic.
- Patient Switching: Switching is not universally mandatory. The decision to switch a patient from the originator biologic drug to a biosimilar rests primarily with the treating physician in consultation with the patient and takes into account any policies of the relevant jurisdiction.
- Maintaining Market Share: Strategies/initiatives undertaken by the manufacturer of the originator biologic may limit the uptake of biosimilars.
Since May 2019, several Canadian payers have undertaken a number of initiatives to encouraging switching from biologics to biosimilars with an aim of increasing biosimilar uptake, as outlined in the table below.
Payer | Initiative | |
---|---|---|
Public payers |
British Columbia |
In 2019, British Columbia became the first Canadian province to initiate a switch to biosimilar medicines for patients covered under the PharmaCare program. Under the Phase 1 & 2 policy initiatives, patients using Enbrel, Remicade, and Lantus for specific indications are required to switch to the biosimilar. The switching policy expanded to Phase 3 & 4 in 2020 and 2021 to include Rituxan and Humira. |
Alberta |
Effective Jan. 2021, Alberta announced that all patients taking Enbrel, Remicade, Lantus, Neupogen, Neulasta, Rituxan, and Copaxone for indications ranging from rheumatoid arthritis to diabetes and multiple sclerosis are required to switch to the biosimilar. This policy has since been expanded to include Humira, Lovenox, and Hamlog. |
|
New Brunswick |
Effective Apr. 2021, New Brunswick only reimburses biosimilar versions of approved indications of Humira, Enbrel, Remicade, Lantus, Humalog, Rituxan, Copaxone, and Lovenox. |
|
Quebec |
Effective Apr. 2021, the Quebec government announced a non-medical switching policy to require patients covered by the Quebec public drug plan who are treated with biologics drugs to switch to biosimilar versions where available and on an ongoing basis. |
|
MB, ON, NS, PEI, NL,YT, NIHB |
Planning to implement biosimilar switching strategies. |
|
Private payers |
Green Shield Canada (GSC), Sun Life and Pacific Blue Cross (PBC) have introduced policy initiatives to promote the use of biosimilar drugs. |
These biosimilar switching policies have prompted wider uptake of biosimilar use in their respective jurisdictions. Infliximab, which holds one of the first biosimilar sales
in Canada, was among the medicines targeted by British Columbia PharmaCare’s Biosimilars Initiative. As a result of this initiative, biosimilars now account for 94% of the infliximab market in British Columbia, compared to just 30% of infliximab units sold nationally.

Cost savings opportunities from biosimilars
As the historic savings from generic price reductions and substitutions begin to wane, savings from biosimilars could play in increasing role in offsetting rising drug costs. Given that these switching initiatives are implemented at the jurisdiction level and by payer, Canada offers a unique model to observe the impacts of variations in approach and timing of biosimilar uptake across jurisdictions.
National market penetration in line with the results seen in British Columbia may bear significant cost implications for Canadian payers, as evidenced by the increased use of three biosimilars targeted by British Columbia PharmaCare’s Biosimilars Initiative: infliximab, etanercept, and insulin glargine 100IU. These biosimilars saved Canadians an estimated $168 million and $232 million in 2020 and 2021, respectively. If national uptake for these biosimilars had followed the trends in British Columbia, additional savings of nearly $1.1 billion would have been attained from 2020 to 2021.
As of the end of 2021, Canadians had only realized a fraction (30%) of the potential savings from the use of these biosimilars, with up to 70% in annual cost savings if biosimilar switching initiatives were implemented across all payers on a national scale.

Figure description
A horizontal bar graph shows the difference between realized and unrealized potential savings from increased biosimilar uptake and/or lower prices in Canada in 2020 and 2021. Results are given as a percentage of the total potential savings and as a dollar amount.
In 2020, realized savings amounted to $168 million (or 23% of total potential savings), leaving $546 million (77%) in unrealized potential savings.
In 2021, realized savings amounted to $232 million (or 30% of total potential savings), leaving $537 million (70%) in unrealized potential savings.
A table below the graph breaks these results down by biologic medicine.
