The De Novo grant letter from the FDA is typically sent via email to the applicant's designated contact. The email is a formal communication notifying the applicant that their device has been granted De Novo classification and is approved for marketing.
As for the time of day the letter is sent, the FDA typically sends such communications during normal business hours (Monday through Friday, 9:00 AM to 5:00 PM Eastern Time), but the exact time can vary. The letter is usually sent once the review process is complete and the decision is made, which could happen at any point during the day within business hours. However, FDA communications are generally not sent outside of business hours or on weekends unless there is a specific urgent reason, such as in public health emergencies.
If an applicant does not receive the letter within the expected timeframe, it is advisable to contact the FDA for clarification. the FDA can send a De Novo grant letter during the last week of the year, but it's important to note that there may be delays due to several factors:
1. FDA Operations During the Holiday Season: The FDA generally operates on a regular schedule, but like many government agencies, it may observe holiday closures. The last week of the year, especially around Christmas and New Year’s, could see reduced staffing or holiday breaks, which could impact the timing of communications.
2. Timing of Approval: If a device has completed the review process and all conditions for approval are met, the De Novo grant letter could be issued during this period, assuming the staff is available to finalize the review. However, it's possible that some decisions might be delayed due to the holiday schedule.
3. Business Days: Since the FDA typically sends emails and official letters during business hours, they might aim to finalize decisions before the holidays, but if the review process extends into the last week of the year, the letter could be issued then, depending on the status of the review.
If you're an applicant awaiting a De Novo decision, it may be helpful to contact the FDA to confirm the status of your submission if you're concerned about timing during this period.
