The Director General of the Agence nationale de sécurité du médicament et des produits de santé may notify the sponsor of any objections to the implementation of the research in a reasoned letter. He will inform the relevant personal data protection committee. It sets a deadline for the sponsor to submit its amended project. The sponsor may amend the content of his research project and send it to the Director General of the Agency within the time limit set. This deadline does not suspend the deadline for the Director General to decide on the application for authorisation pursuant to Article R. 1125-10. This amendment procedure may only be applied once to each research project. Any sponsor who does not submit an amended project within the time limit set is deemed to have withdrawn the application.
