Health Products and Food Branch

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.

HPFB has seven operational Directorates with direct regulatory responsibilities:

Extraordinary Use New Drugs

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.
