Submit Your Master Files

Guard Your Proprietary Product Data with a Master File Submission

A Master File is a secure, confidential submission of proprietary product data to a regulatory agency, such as the U.S. Food and Drug Administration (FDA), Health Canada, or National Medical Products Association (NMPA) in China.

Registrar Corp prepares and submits Drug, Medical Device, and Veterinary Master Files to 18 regulatory agencies worldwide.

What is a Master File?

As part of certain drug and medical device applications to regulatory agencies, a company may need to reference data from another product used in the manufacture of their own, such as packaging, ingredients, or accessories.  The owner of this data may choose to submit a Master File to disclose proprietary or confidential information concerning their product to a regulatory agency without providing it to parties that need to reference it.

Many agencies require submission of Master Files in electronic common technical document (eCTD) format.

Drug Master Files (DMFs) & Other Common Types of Master Files

Drug Master Files (DMFs) and Active Substance Master Files (ASMFs)

Submissions of proprietary information on human drugs and substances, including information on:

  • Drug substances and products
  • Packaging materials
  • Excipients and preparation materials
  • Facilities and their procedures
  • and More

Medical Device Master Files (MAFs)

Submissions of proprietary information on medical devices, including information on:

  • Facilities and their procedures
  • Device formulations
  • Packaging materials
  • Clinical and non-clinical study data

Submit your Master Files in eCTD

What is eCTD?

Electronic common technical document (eCTD) format is a standard submission format for Master Files. Agencies such as FDA and Health Canada require eCTD format for certain types of Master File submissions, including DMFs and ASMFs.

Should I Convert My Existing Master File to eCTD?

eCTD requirements vary per agency.  Existing Master Files that are not in eCTD format, including those in paper form, typically do not require resubmission to FDA; however, additional submissions such as annual reports, supplements, and amendments must be submitted to FDA in eCTD.  Likewise, Health Canada requires all Master Files to be submitted in an electronic format that may be eCTD.

Regardless of requirements, companies typically convert their existing paper Master Files to eCTD to expedite the review process of an NDA or ANDA that references the Master File.

How Do I File an eCTD Submission?

eCTD submissions are typically required to be sent through an Electronic Submissions Gateway (ESG).  Access to an agency’s ESG often involves a lengthy application and computer configuration process. This process may require several weeks of preparation, agency correspondence, and testing.

Alternatively many companies choose to hire a Regulatory Specialist, such as Registrar Corp, to convert their Master File submissions to eCTD format and submit the Master File on their behalf.

    Is your Food Safety Plan FDA-Compliant?

    U.S. FDA requires most types of registered food facilities to implement Hazard Analysis and Risk-Based Preventive Controls (HARPC) Plans. A HARPC plan must follow unique standards mandated by U.S. FDA. Other food safety systems may not completely satisfy FDA requirements.

  • Food Label Deadline

    Deadline Approaching for FDA's New Label Rules

    Many food companies have less than 12 months to update their labeling to comply with new FDA labeling rules. The new rules include updates to the nutrition facts chart, serving sizes, mandatory declarations, and more.

  • Food Label Deadline

    Labeling mistakes result in more than 22% of all detentions in the United States.

    Many companies do not realize their labels are non-compliant until their products are detained, which may result in delays, re-labeling expenses, or destruction of inventory. Help avoid costly issues in port. Have Registrar Corp's experts assess the FDA compliance of your labels.
