Drug submissions: Procedures to reach regulatory approval
Read time: 4 mins
Read the highlights
- It’s necessary follow a drug submission and regulatory approval process with all relevant agencies before you can market a new drug or biologic.
- Canada, the US and the EU each require different types of drug submissions and have their own review procedures. Despite these difference, the review stages generally follow a similar path from the pre-submission meeting to the regulatory decision.
Before a new drug or biologic can go to market, a drug submission must be compiled and filed with all relevant regulatory agencies to seek a review and, ultimately, regulatory approval.
Canada, the US and the EU each require different types of drug submissions (Table 11-4 ).
Table 1: Drug submission types: Canada, the US and the EU
|Canada||New Drug Submission (NDS)―for both drugs and biologics|
|US||New Drug Application (NDA)―for drugs
Niologic License Application (BLA)―for biologics
|EU||Marketing Authorization Application (MAA)―via the centralized procedure for eligible products (Table 24). For other products, routes such as the decentralized procedure, the mutual recognization procedure or national authorization apply.|

Review and approval procedures for drug submissions
Each jurisdiction has its own procedures to review drug submissions filed to their regulatory agency. These procedures can vary substantially with respect to how the drug submission will be handled, the composition of the review team, review timelines and so on.1-4
Despite the differences, the procedures to reach regulatory approval generally follow these stages:
Although optional, a pre-submission meeting5 is often useful so that any scientific or submission issues can be discussed and resolved prior to the actual submission. This meeting also provides the agency insight into your drug or biologic submission and allows them to organize their internal resources accordingly.
Tip: Ensure the issues discussed are addressed in the submission dossier, with additional data or a sound scientific justification provided.
Review what communication is required prior to submitting your marketing application. In Canada, sponsors (that is, applicants) are requested to send advance requests for Priority Review status and for Requests for Advance Consideration under the NOC/c.6 In the EU, an applicant should notify the European Medicines Agency (EMA) of its intention to submit via the centralized procedure at least seven months before the drug submission.7 Any orphan drug designation should also be requested and approved before your drug submission will be reviewed as an orphan product.
Once a drug submission is filed, it goes through an administrative review to ensure its acceptability (for example, completeness). A submission number (such as NDS Control Number or NDA number) is assigned and this number must be used in all subsequent communication with the regulatory agency.
If the drug submission is found to be acceptable at this stage, it will be accepted for review. If minor deficiencies are identified (for example, missing forms), the agency will normally allow the sponsor time to respond. If the response is satisfactory, then the submission will proceed to review. If the sponsor fails to provide the requested information within the set timeframe, or if that the response is unsatisfactory, the agency can reject (refuse to file) the submission.
Tip: Adhere to the response timeline indicated. Should you need more time, contact the agency and request an extension, providing a justification. The agency will determine if an extension can be granted.
Agency review and sponsor response
Once a drug submission is accepted, it is evaluated by reviewers with the necessary expertise. In the US, for example, a review team may include clinicians, pharmacokineticists, pharmacologists, toxicologists, statisticians, microbiologists and chemists, as well as a regulatory project manager (RPM). The objective of the review is to confirm and validate the sponsor’s conclusion that the drug is safe and effective for its proposed use.
Once the technical review is complete, an evaluation report will be generated. If the submission is deemed acceptable, then the technical review of the submission is complete. If deficiencies are identified, then the agency will issue a list of questions for the sponsor to address within a set timeline.
This review also evaluates the text in the proposed labelling, which needs to be justified by the data submitted in the submission. If the reviewers question the proposed labelling, they will discuss revised wording with the sponsor.
Tip: Assemble a response team that can address agency questions and requests for additional information. A quick response by the sponsor facilitates the review process.
Activities prior to the agency’s decision
These may include any necessarypre-approval inspections (for example, of drug manufacturing sites or clinical trial sites). In the US, for example, the Food and Drug Administration (FDA) may decide to convene an advisory committee (AC) meeting and seek input. Based on the discussions at the AC meeting and its recommendations, the FDA may ask for additional data or analyses to review.
The decision made at the end of the review process normally results in regulatory approval, an approval with conditions, or a rejection.
*NOC/c = Notice of Compliance with conditions
Summary: You must follow a drug submission and regulatory approval process with all relevant agencies before you can market a new drug or biologic; Canada, the US and the EU have different drug submission requirements.
