Health Canada's Clinical Trials Database - Website

Health Canada, through its Clinical Trials Database, is providing the public with a listing of specific information relating to phase I, II, and III clinical trials in patients. The database is managed by Health Canada and provides a source of information about Canadian clinical trials involving human pharmaceutical and biological drugs.

Access the Clinical Trials Database

Patients can access the database to determine if a clinical trial has met the regulatory requirements. The database may also assist Canadians in finding clinical trials that might be relevant to their medical relevant to their medical condition

The Clinical Trials Database is not a registry, and therefore, it does not contain comprehensive information about each clinical trial. To maximize the use of the database and available information, users are advised to link to external resources, including publicly available registries, to obtain further information such as trial objectives and patient eligibility

Note, however, that not all clinical trials are necessarily registered and thus found in registries.

Health Canada continues to encourage sponsors to register their clinical trials in publicly accessible registries such as ClinicalTrials.gov and ISRCTN.

A Canadian-based registry for cancer trials is also available at Canadian Cancer Trials. Additionally, the search portal provided by the World Health Organization (WHO) can be used to access a central database that contains information about trials registered in several international registries.

Health Canada is the federal regulator responsible for authorizing the importation and sale of drugs for clinical trials. This responsibility is fulfilled through the review of clinical trial applications (CTAs) for phase I, II, and III clinical trials filed by clinical trial sponsors. One objective of Health Canada's review is to ascertain that subjects participating in the trial will not be exposed to unknown risks.
