For any application for authorisation for research involving the human person carried out in the context of medically assisted procreation, the Director General of the Agence nationale de sécurité du médicament et des produits de santé sends a copy of the complete dossier to the Director General of the Agence de la biomédecine for an opinion. The Director General of the Agence de la biomédecine will give his opinion to the Director General of the Agence nationale de sécurité du médicament et des produits de santé within forty days of the date of transmission of the dossier. Failure by the Director General of the Agence de la biomédecine to respond within this period will be deemed to constitute a favourable opinion. The Director General of the Agence nationale de sécurité du médicament et des produits de santé will send a copy of his decision to the Director General of the Agence de la biomédecine. He will also send the Director General of the Agence de la biomédecine a copy of the decision to substantially modify the research where this concerns the Agence de la biomédecine.
