Canadian drug regulatory framework.
The role of regulatory drug submission evaluators in Canada is to critically assess both the data submitted and the sponsor's interpretation of the data in order to reach an evidence-, and context-based recommendation as to the potential benefits and potential harms (i.e., risks) associated with taking the drug under the proposed conditions of use. The purpose of this document is to outline the regulatory framework in which this assessment occurs, including: defining what "authorization to market a drug in Canada" means, in terms of the role of the sponsor, the responsibility of Health Canada in applying the Food and Drugs Act prior to and after marketing authorization, and the distinction between regulatory authorization versus physician authorization; highlighting organizational, process and legal factors within Health Canada related to authorization of clinical trials and authorization to market a drug; considerations during the review process, such as regulatory and scientific issues related to the drug, patient populations and trial designs; application of international guidelines, and decisions from other jurisdictions; regulatory realities regarding drug authorization, including the requirement for wording in the Product Monograph to accurately reflect the information currently available on the safe and effective use of a drug, and that hypothesis-confirming studies are essential to regulatory endorsement; current issues related to the review of therapies for dementia, such as assessing preventative treatments, and therapies that have symptomatic versus disease-modifying effects, statistical issues regarding missing data, and trial design issues.
