Regulatory response to COVID-19
The COVID-19 pandemic has created an unprecedented demand on Canada’s health care system and has led to an urgent need for access to health products.
As part of the government’s broad response to the pandemic, Health Canada introduced innovative and agile regulatory measures. These measures expedite the regulatory review of COVID-19 health products without compromising safety, efficacy and quality standards.
These measures are helping to make health products needed for COVID-19, such as investigational drugs and vaccines, available to Canadians and health care workers.
We are also working with our international partners on a coordinated and well-aligned approach to this global pandemic. This ensures that our policies and regulatory approaches are aligned and that health products are safe, effective and quickly available to Canadians. Collaboration also helps advance the development of diagnostics, treatments and vaccines that will save lives and protect the health and safety of people everywhere.
Regulating drugs and vaccines sold in Canada
Drugs, including vaccines, are regulated under the Food and Drugs Act and Regulations. They must meet the regulatory requirements for safety, efficacy and quality before they can be sold in Canada. Health Canada's regulatory process involves:
- authorizing the use of a product in a clinical trial
- reviewing data and evidence to provide a product market authorization and
- monitoring and assessing the safety of a product once it is on the Canadian market
On July 27, 2020, Health Canada granted authorization with conditions for the use of Veklury (remdesivir) to treat COVID-19 in patients with pneumonia requiring supplemental oxygen. Remdesivir is the first drug to be authorized in Canada for the treatment of COVID-19.
There are currently no vaccines authorized for COVID-19. Certain authorized products may ease COVID-19 symptoms, such as fever and cough.
Clinical trials for drugs and vaccines
Clinical trials are the most appropriate way for Canadians to access experimental drugs or vaccines that could help treat or prevent COVID-19. During a trial, companies or sponsors collect information on the risks and benefits of a drug or vaccine. Participants must give their informed consent in order to participate.
Sponsors must apply to conduct a clinical trial in Canada. On May 23, 2020, the Minister of Health signed the interim order for clinical trials for medical devices and drugs related to COVID-19. The interim order responds to the urgent need for COVID-19 diagnosis, treatment, mitigation or prevention options. It introduces a new pathway to facilitate the conduct of clinical trials in Canada to investigate and offer patient access to potential COVID-19 drugs and medical devices, while upholding strong patient safety requirements.
In addition to the interim order, Health Canada is working hard to expedite the authorization of trials for COVID-19. We are reviewing applications faster than we usually would to speed up access. We are also encouraging companies, academic research centres and investigators who have products in development and pre-clinical data to contact us before they apply so we can advise them on the regulatory process.
See Health Canada's complete list of authorized clinical trials for drugs and vaccines for COVID-19. For a broader list all authorized clinical trials, including those not related to COVID-19, please visit Health Canada's clinical trials database.
Potential drugs and vaccines
There are many potential drugs being investigated in Canada and around the world for use against COVID-19. We are closely tracking all potential drugs and vaccines in development.
Potential COVID-19 drugs currently being investigated in Canadian clinical trials include:
- antiviral drugs
- anti-malarial drugs
- monoclonal antibodies and other drugs that address inflammation
- convalescent plasma collected from patients who have recovered from COVID-19
- medical gases
Health Canada reviews scientific evidence of a drug or vaccine, including results from clinical trials, to assess the product's safety, efficacy and quality before it can be sold in Canada. To facilitate earlier access to COVID-19 drugs or vaccines, Health Canada is prioritizing the review of these products while ensuring there is adequate evidence of safety, efficacy and quality to merit access to Canadians. The Department can also grant market authorization with certain restrictions (Notice of Compliance with Conditions - NOC/c).
Health Canada is also collaborating with international counterparts and leveraging all available knowledge to the extent possible to support and expedite the authorization of drugs for COVID-19 in Canada. Domestically, we actively engage with industry associations and specific drug sponsors to learn as much as possible about potential therapies and facilitate their availability in Canada.
Special Access Program
The most appropriate way to access unproven treatments is through clinical trials. However, the Special Access Program (SAP) is also available to healthcare professionals who are treating seriously-ill patients where conventional therapies have failed, are unsuitable, or unavailable. The SAP authorizes a manufacturer to sell a drug that cannot otherwise be sold or distributed in Canada.
To access products under the SAP, health care professionals must ask Health Canada for permission and companies must agree to provide the product. We will review the evidence on the drug's safety and efficacy for use in a medical emergency. We will consider each request separately.
