Does Health Canada require separate Clinical Trial Applications for each protocol?
Does Health Canada require separate Clinical Trial Applications for each protocol is a question often asked. Presently, drug developers may submit more than one protocol into one single clinical trial application (CTA), when the Application is submitted to the Therapeutic Drug Directorate (TPD). Each protocol would then be considered a different dossier with a different control number per protocol; an approval per protocol would apply. When the CTA is submitted to the Biologic and Genetic Therapies Directorate (BGTD), one protocol only can be submitted per CTA. The upcoming electronic submission requirements for the CTA will likely impose the submission of one protocol per CTA for both Directorates.
Even with these differences, globally the process is quite similar in the US and Canada, however, the terminology used is different and this can cause some confusion.
In the U.S., we see one IND per product under clinical development, which is open to adding new protocol amendments etc… Clinical holds can apply to these INDs and the duration of the holds may vary. In Canada, there is a clinical trial application process, whereby one or more protocols can be submitted at once. New protocols are submitted as new CTAs. There are amendments and notifications that can be brought to clinical trial applications that are approved.
An amendment is considered a major change to an approved protocol or quality dossier, and therefore requires the same 30-day default review period. Minor changes are submitted as notifications within 15 days of the implementation of the change and no review period applies. Now, as mentioned, a new protocol must be submitted via a new clinical trial application. However, cross-referencing to an approved clinical trial application already on file for sections that are not changed, is possible. For example, cross-referencing to an approved investigator’s brochure or to an approved quality dossier. Therefore, it reduces the submission requirement and content. The process is simple and very similar to an IND amendment in the U.S., even if it’s classified as a clinical trial application in Canada.
