Investigational drug

A drug that has been tested in the laboratory and has been approved by Health Canada for testing in people. Clinical trials test how well investigational drugs work and whether they are safe to use. An investigational drug may be approved by the Health Canada for use in one disease or condition but still be considered investigational in other diseases or conditions (off-label). Health Canada recently introduced a process for evaluating off-label use of authorized drugs in clinical trials.
