The competent authority may, at any time, ask the sponsor for additional information about the research.
If there is a risk to public health or if the sponsor fails to respond, or if the competent authority considers that the conditions under which the research is being carried out no longer correspond to the conditions indicated in the application for authorisation referred to in Article L. 1123-8 or do not comply with the provisions of this Title, it may at any time request that changes be made to the procedures for carrying out the research or to any document relating to the research, and may suspend or prohibit the research.
Except in cases of imminent risk, a modification of the protocol at the request of the competent authority or a decision to suspend or prohibit the research may only be made after the sponsor has been given the opportunity to present its observations.
The sponsor must inform the competent Committee for the Protection of Individuals and the competent authority referred to in Article L. 1123-12 of the start and end of the research involving the human person and give the reasons for stopping the research when this is anticipated.
