  • tombstone submission information, i.e. control number (“submission number”), submission type, submission class, Lead Bureau/Office, date of filing (also known as “CR date”), dossier ID
  • drug product information, i.e. product name, manufacturer, country, active ingredient
  • status history information, i.e. submission status, status date and target date
  • review history information, i.e. review details including review type, division, status of the review (i.e. pending, active, completed) and status dates
  • document history, i.e. documents issued and received, including dates

For information regarding DSTS-IA, or for account set up, please contact the Office of Submission and Intellectual Property by sending an e-mail to:

Please note that this change will not impact those submissions or supplements that require a certification as per the Patented Medicines (Notice of Compliance) Regulations, these regulatory activities will continue to receive a letter of Acknowledgement and Certification of Information Received once they are deemed administratively complete.
