A clinical trial of a medical device can begin how many days after notification is sent to the Competent Authority?

The correct answer is based on the regulatory framework governing clinical trials for medical devices. In this context, a clinical trial can begin 60 days after the notification is sent to the Competent Authority if no objections are raised during that time period.

The 60-day timeframe is essential for ensuring that the Competent Authority has adequate time to review the trial protocol and assess any potential risks associated with the medical device being tested. If the Competent Authority does not respond within these 60 days, the trial can proceed as planned.

In contrast, starting the trial as soon as Ethical Committee approval is received does not take into account the requirement for notifying the Competent Authority, which is a crucial step in the regulatory process. Choosing a shorter timeframe like 30 or 45 days would not align with the established regulatory guidelines and would not provide a sufficient window for the authority to conduct a thorough review.
