The Health Products and Food Branch (HPFB) of Health Canada manages the health-related risks and benefits of health products and food by minimizing risk factors while maximizing the safety provided by the regulatory system and providing information to Canadians so they can make healthy, informed decisions about their health.
HPFB has ten operational Directorates with direct regulatory responsibilities:
Extraordinary Use New Drugs (EUNDs) is a regulatory programme under which, in times of emergency, drugs can be granted regulatory approval under the Food and Drug Act and its regulations. [1] [2] [3] [4] An EUND approved through this pathway can only be sold to federal, provincial, territorial and municipal governments. [5] The text of the EUNDs regulations is available. [6]
On 25 March 2011 [5] and after the pH1N1 pandemic, [3] amendments were made to the Food and Drug Regulations (FDR) to include a specific regulatory pathway for EUNDs. Typically, clinical trials in human subjects are conducted and the results are provided as part of the clinical information package of a New Drug Submission (NDS) to Health Canada, the federal authority that reviews the safety and efficacy of human drugs. [2]
Health Canada recognizes that there are circumstances in which sponsors cannot reasonably provide substantial evidence demonstrating the safety and efficacy of a therapeutic product for NDS as there are logistical or ethical challenges in conducting the appropriate human clinical trials. The EUND pathway was developed to allow a mechanism for authorization of these drugs based on non-clinical and limited clinical information. A manufacturer of a new drug may file an extraordinary use new drug submission for the new drug if, under paragraph C.08.002.01(1): [2]
(a) the new drug is intended for
- (i) emergency use in situations where persons have been exposed to a chemical, biological, radiological or nuclear substance and action is required to treat, mitigate or prevent a life-threatening or other serious disease, disorder or abnormal physical state, or its symptoms, that results, or is likely to result, from that exposure, or
- (ii) preventative use in persons who are at risk of exposure to a chemical, biological, radiological or nuclear substance that is potentially lethal or permanently disabling; and
(b) the requirements set out in paragraphs C.08.002(2)(g) and (h) cannot be met because
- (i) exposing human volunteers to the substance referred to in paragraph (a) would be potentially lethal or permanently disabling, and
- (ii) the circumstances in which exposure to the substance occurs are sporadic and infrequent.
The HPFB signed an electronic data interchange agreement with the US Food and Drug Administration in November 2003, and again in April 2004 with the Therapeutic Goods Administration of Australia. Dr Joel Lexchin found the secrecy arrangements in the memorandum of understanding to be troublesome and said that "that just makes it more difficult for the medical community to know how drugs were approved, how the data were assessed, and even what data were assessed." [7]
In 2016, the HPFB signed an agreement with the European Directorate for the Quality of Medicines "for the exchange of information generated by the EDQM through its certification procedure and by HBFB during the course of applicable product assessments." [8]
The United States Food and Drug Administration is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products.
Pharmacology is the science of drugs and medications, including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
Health Canada is the department of the Government of Canada responsible for national health policy. The department itself is also responsible for numerous federal health-related agencies, including the Canadian Food Inspection Agency (CFIA) and the Public Health Agency of Canada (PHAC), among others. These organizations help to ensure compliance with federal law in a variety of healthcare, agricultural, and pharmaceutical activities. This responsibility also involves extensive collaboration with various other federal- and provincial-level organizations in order to ensure the safety of food, health, and pharmaceutical products—including the regulation of health research and pharmaceutical manufacturing/testing facilities.
The minister of health is the minister of the Crown in the Canadian Cabinet who is responsible for overseeing health-focused government agencies including Health Canada and the Public Health Agency of Canada, as well as enforcing the Canada Health Act, the law governing Canada's universal health care system.
The pregnancy category of a medication is an assessment of the risk of fetal injury due to the pharmaceutical, if it is used as directed by the mother during pregnancy. It does not include any risks conferred by pharmaceutical agents or their metabolites in breast milk.
Current good manufacturing practices (cGMP) are those conforming to the guidelines recommended by relevant agencies. Those agencies control the authorization and licensing of the manufacture and sale of food and beverages, cosmetics, pharmaceutical products, dietary supplements, and medical devices. These guidelines provide minimum requirements that a manufacturer must meet to assure that their products are consistently high in quality, from batch to batch, for their intended use.
The regulation of therapeutic goods, defined as drugs and therapeutic devices, varies by jurisdiction. In some countries, such as the United States, they are regulated at the national level by a single agency. In other jurisdictions they are regulated at the state level, or at both state and national levels by various bodies, as in Australia.
The United States Federal Food, Drug, and Cosmetic Act is a set of laws passed by the United States Congress in 1938 giving authority to the U.S. Food and Drug Administration (FDA) to oversee the safety of food, drugs, medical devices, and cosmetics. The FDA's principal representative with members of congress during its drafting was Charles W. Crawford. A principal author of this law was Royal S. Copeland, a three-term U.S. senator from New York. In 1968, the Electronic Product Radiation Control provisions were added to the FD&C. Also in that year the FDA formed the Drug Efficacy Study Implementation (DESI) to incorporate into FD&C regulations the recommendations from a National Academy of Sciences investigation of effectiveness of previously marketed drugs. The act has been amended many times, most recently to add requirements about bioterrorism preparations.
The Food and Drug Administration's (FDA) New Drug Application (NDA) is the vehicle in the United States through which drug sponsors formally propose that the FDA approve a new pharmaceutical for sale and marketing. Some 30% or less of initial drug candidates proceed through the entire multi-year process of drug development, concluding with an approved NDA, if successful.
The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) is an initiative that brings together regulatory authorities and pharmaceutical industry to discuss scientific and technical aspects of pharmaceutical product development and registration. The mission of the ICH is to promote public health by achieving greater harmonisation through the development of technical guidelines and requirements for pharmaceutical product registration.
The Food and Drugs Act is an act of the Parliament of Canada regarding the production, import, export, transport across provinces and sale of food, drugs, contraceptive devices and cosmetics. It was first passed in 1920 and most recently revised in 1985. It attempts to ensure that these products are safe, that their ingredients are disclosed and that drugs are effective and are not sold as food or cosmetics. It also states that cures for disease listed in Schedule A, cannot be advertised to the general public.
A biopharmaceutical, also known as a biological medical product, or biologic, is any pharmaceutical drug product manufactured in, extracted from, or semisynthesized from biological sources. Different from totally synthesized pharmaceuticals, they include vaccines, whole blood, blood components, allergenics, somatic cells, gene therapies, tissues, recombinant therapeutic protein, and living medicines used in cell therapy. Biologics can be composed of sugars, proteins, nucleic acids, or complex combinations of these substances, or may be living cells or tissues. They are isolated from living sources—human, animal, plant, fungal, or microbial. They can be used in both human and animal medicine.
The Principles of Good Laboratory Practice (GLP) establish rules and criteria for a quality system that oversees the organizational processes and conditions in which non-clinical health and environmental safety studies are planned, conducted, monitored, recorded, reported, and archived. These principles apply to the non-clinical safety testing of substances found in various products to ensure the quality and integrity of the safety data submitted to regulatory authorities globally.
The European Directorate for the Quality of Medicines & HealthCare (EDQM) is a Directorate and partial agreement of the Council of Europe that traces its origins and statutes to the Convention on the Elaboration of a European Pharmacopoeia.
The Pest Management Regulatory Agency (PMRA) is the Canadian government agency responsible for the regulation of pest control products in Canada under the federal authority of the Pest Control Products Act and Regulations. The agency is a branch that reports to Parliament through Health Canada. The PMRA is responsible for providing access to pest management tools while minimizing the risks to human health and the environment by “using modern evidence-based scientific approaches to pesticide regulation, in an open and transparent manner”. Their main activity areas include: new product evaluation, post market review and compliance and enforcement.
An experimental drug is a medicinal product that has not yet received approval from governmental regulatory authorities for routine use in human or veterinary medicine. A medicinal product may be approved for use in one disease or condition but still be considered experimental for other diseases or conditions.
Safety pharmacology is a branch of pharmacology specialising in detecting and investigating potential undesirable pharmacodynamic effects of new chemical entities (NCEs) on physiological functions in relation to exposure in the therapeutic range and above.
The following outline is provided as an overview of and topical guide to clinical research:
The Food and Drug Administration Safety and Innovation Act of 2012 (FDASIA) is a piece of American regulatory legislation signed into law on July 9, 2012. It gives the United States Food and Drug Administration (FDA) the authority to collect user fees from the medical industry to fund reviews of innovator drugs, medical devices, generic drugs and biosimilar biologics. It also creates the breakthrough therapy designation program and extends the priority review voucher program to make eligible rare pediatric diseases. The measure was passed by 96 senators voting for and one voting against.
Consumer Health Laws are laws that ensure that health products are safe and effective and that health professionals are competent; that government agencies enforce the laws and keep the public informed; professional, voluntary, and business organizations that serve as consumer advocates, monitor government agencies that issue safety regulations, and provide trustworthy information about health products and services; education of the consumer to permit freedom of choice based on an understanding of scientific data rather than misleading information; action by individuals to register complaints when they have been deceived, misled, overcharged, or victimized by frauds.
