Biologics and Biosimilars

Biologic drugs represent a major step forward in treating inflammatory forms of arthritis such as rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. These advanced medications are produced through complex processes involving living organisms, and are designed to interfere with the body's inflammatory response in various ways.

As original biologics come off patent, new medications called biosimilars (sometimes called subsequent entry biologics or SEBs) are now available in Canada, offering additional treatment options for Canadians with inflammatory arthritis.

For detailed information about particular medications, see our Arthritis Medication Guide.

The Arthritis Society’s position paper (pdf) addresses the place of biosimilars in the range of approved treatment options in Canada, to help inform patients, physicians, drug plan providers and regulators. For more on this and our other advocacy efforts, visit our Advocacy page.


Biologics (including biosimilars) are powerful but complex medications. These resources are designed to help you better understand these drugs, how they are different from other traditional drugs, how they work, and what you need to be aware of as you consider your treatment options.
