Draft guidance on human and veterinary drug submissions based on promising evidence and terms and conditions: Before filing a submission

On this page

Before filing a new drug submission or supplement to a new drug submission for human and veterinary drugs based on promising evidence of efficacy

We ask that manufacturers request a pre-submission meeting in advance of filing a new drug submission (NDS) or supplement to a new drug submission (SNDS) for human and veterinary drugs seeking market authorization of their drug, on the basis of promising evidence of clinical efficacy.

Pre-submission meeting

Manufacturers should submit a pre-submission/application meeting package in one of the acceptable file formats.

For more information on the pre-submission meeting process, refer to:

Veterinary drugs – Pre-submission

For veterinary drugs, manufacturers should submit a pre-submission meeting package at least one month in advance of the meeting. In addition to the information to be included in the pre-submission meeting package as per the Management of regulatory submissions guidance, the following information should be provided as an appendix to the pre-submission package:

We will notify the manufacturer if a NDS or SNDS contains the necessary information to be considered as a submission based on promising evidence of efficacy within 14 calendar days after the pre-submission meeting minutes are finalized.

Unless otherwise agreed to in the pre-submission meeting, submissions should be filed within 6 months of receiving this confirmation, or a new pre-submission meeting may be required. A copy of this confirmation should be included in the submission.

Advance consideration of human drug submissions filed with promising evidence of efficacy

Manufacturers may seek a shorter screening and review target for their drug submission by requesting advance consideration of promising evidence (ACPE) status. ACPE status will be granted for submissions based on promising evidence if specific criteria are met. Refer to the following in this guidance:

Manufacturers should state within their pre-submission meeting request that they are seeking ACPE status. The request for ACPE template is to be completed and filed at the same time as the filing of the pre-submission meeting package. We will use the completed request as part of the initial assessment to determine if the drug submission will be granted a reduced screening and review targets.

We will grant or deny a request for ACPE status based on the assessment of the information provided in the ACPE template, the pre-submission meeting package and the pre-submission meeting minutes. We will inform manufacturers of our decision within 14 calendar days of receipt of the final pre-submission meeting minutes by the review bureau. This will be communicated to manufacturers through the issuance of an acceptance or denial letter for ACPE.

If ACPE is granted, the drug submission will be referred to as a drug submission based on promising evidence and will be subject to reduced screening and review targets.

The sponsor should clearly state in their cover letter when filing the drug submission that it has been granted ACPE. A copy of the acceptance letter should be included. The submission should be filed within 60 calendar days of the date of the acceptance letter (Figure 1).

We encourage manufacturers who file drug submissions to work with us and the relevant health technology assessment organizations on an aligned review:

For additional information related to the aligned review process, refer to:

Denial of a request for advance consideration of a human drug submission filed based on promising evidence of efficacy

We may deny a request for ACPE of a drug submission based on promising evidence of efficacy for reasons such as:

If the request for ACPE status is denied and a submission is filed, the submission screening and review targets will not be reduced.

Revised request following denial of a request for advance consideration of promising evidence for a human drug submission

If we deny a request for ACPE, the manufacturer has 30 calendar days from the date of the decision letter to file a revised request for ACPE. The document must clearly denote the new information submitted (for example, new results for ongoing clinical studies). Failure to provide new information will result in denial of the request. Health Canada will review the revised request for ACPE within 30 calendar days and will communicate its decision through the issuance of an acceptance or denial letter.

If we deny the revised ACPE request, no further requests based upon the same proposed indication for the drug will be considered for an ACPE.

Assessment of information in pre-submission meeting package

We will consider the current standard of care, which may or may not be the same as that used in the relevant clinical study in the planned NDS or SNDS when assessing the pre-submission meeting package as well as the information presented at the pre-submission meeting, and the ACPE request in the case for human drugs. The onus is on the manufacturer to provide a robust rationale for the selection of the comparator and to analyze the comparative benefit-risk profiles in the context of the current standard of care.

Additional information to be provided

Following a pre-submission meeting, and if ACPE status is granted for human drugs, the manufacturer is asked to include the following in their NDS or SNDS submission package, if available:
