Biosimilars: An Important Solution for Health Care Sustainability and Patient Care
Over the past 50 years biologic medicines have revolutionized the treatment and prevention of many disabling and life-threatening diseases, including diabetes, arthritis, inflammatory digestive disorders and cancers.
But biologic medicines are also expensive. It can cost $10,000 to $25,000 or more to treat one patient on a biologic drug for a year. Public and employer-sponsored drug benefit plans want to expand their coverage of patients to include more innovative new medicines, but they also need to manage costs as the number of patients taking biologic drugs continues to grow.
Biosimilars are an important solution in ensuring the sustainability of drug programs to ensure patients have access to the essential therapies they need for years to come.
Fortunately, an important solution to this challenge has arrived in Canada. Patents on many biologic medicines have expired, and other manufacturers are now able to produce these medicines. These are called biosimilars. More than 65 biosimilars have been authorized for sale by Health Canada, and many more submissions for new biosimilars are under review.
Biosimilars have been a standard fixture in patient care in Europe for more than a decade, and continue to grow in Canada with more than 3 million retail prescriptions filled with biosimilars annually, according to IQVIA data. In addition, many biosimilars are used in hospitals for oncology and other conditions, which are not reflected in retail prescription data.
Switching to Biosimilars is Safe and Effective
Patients with chronic diseases typically use a biologic medicine for many years. As such, biosimilars cannot fully contribute to health care sustainability unless patients on existing original biologic medicines transition to biosimilar medicines. Health Canada’s Biosimilars Fact Sheet confirms patients and health care providers can have confidence that biosimilars are effective and safe for each of their authorized indications, and that no differences are expected in efficacy and safety following a change in routine use between a biosimilar and its reference biologic drug in an authorized indication.
Real-word evidence confirms that patients, healthcare providers and payers can have confidence in the well-established practice of transitioning patients from an original biologic drug to a biosimilar. A peer-reviewed study found that there have been more than 178 clinical trials worldwide involving approximately 21,000 switched patients which confirm that switching from an originator biologic drug to a biosimilar biologic drug is not associated with any major efficacy, safety, or immunogenicity issues.
All ten provinces and two territories have implemented biosimilar transition policies for their public drug benefit programs, as have some federal public drug plans. The Government of British Columbia recently reported that more than 40,000 patients had made the transition to biosimilars under its public drug plan, saving the province more than $732 million over the past five years.
Most private insurance providers now offer biosimilar transition plans, but they are often underutilized. Nationally, the use of biosimilars by private drug plans is about 30% lower than in public drug plans.
As cost pressures continue to increase for all businesses, expanding the use of biosimilars should not be overlooked as an important solution to help employers sustain their drug program and transform the benefits they provide for their employees. Biosimilars Canada has launched the #SaveBigWithBiosimilars campaign and downloadable Employer Handbook on Biosimilars to provide companies with information to unlock the full value of biosimilars to transform their employee health benefits.

The Bottom Line
Patients and clinicians can have confidence in biosimilar medicines. Biosimilars are reviewed and authorized for sale by Health Canada, they are as safe and effective as the corresponding original biologic drug, and they can provide tremendous value to Canada’s health care system.
Switching patients from original biologic drugs to new biosimilar medicines is a responsible choice for those who manage drug budgets, and will help to ensure patient access to essential treatments for years to come.
