Essential Drug Delivery Outputs for Drug Delivery Devices and Combination Products (DRAFT)

This guidance addresses key aspects of drug delivery performance information for devices and combination products with device constituent parts intended for delivery of human drugs and biological products. It focuses on essential drug delivery outputs (EDDOs) - the device design outputs necessary to ensure proper drug delivery function, including product preparation, initiation, progression, and completion of dose delivery.

This is a draft guidance. Not for implementation.

  1. Identify EDDOs early in development using the filtering process outlined in the guidance
  2. Develop verification and validation plans for EDDOs considering:
    • Preconditioning requirements
    • Stability/shelf-life testing needs
    • Appropriate sampling plans
    • Clinical validation where applicable
  3. Establish risk-based control strategy for EDDOs including:
    • Upstream controls (process parameters, incoming materials)
    • Downstream controls (release testing)
    • Documentation requirements
  4. Submit appropriate EDDO information in regulatory applications:
    • Device description and engineering documentation
    • Verification and validation data
    • Control strategy details
    • Risk analysis
  5. Evaluate impact of post-approval changes on EDDOs and update control strategy as needed
  6. Engage with FDA early regarding proposed EDDOs and control strategy through formal meetings
  7. Maintain documentation of EDDO identification, verification, validation and control throughout product lifecycle

Key Considerations

Clinical testing

  • Clinical studies may be used to validate EDDOs
  • Clinical protocols should include endpoints relevant to device performance
  • Safety endpoints should capture device failures and malfunctions

Non-clinical testing

  • Design verification testing after appropriate preconditioning
  • Shelf-life and stability testing for EDDOs that may change over time
  • Risk-based sampling plans considering indication, population, drug, use context
  • Testing should evaluate impact of storage, shipping, and use conditions

Labelling

  • Instructions for use should be considered when identifying EDDOs
  • Labeling changes that could impact EDDOs require evaluation

Safety

  • EDDOs necessary for patient safety should be verified and validated before clinical studies
  • Risk analysis should include EDDO-related risks

Other considerations

  • ANSI/AAMI HE 75:2009 (R2018): Human factors engineering – Design of medical devices
  • ISO 13485:2016: Medical devices – Quality management systems – Requirements for regulatory purposes
  • USP <601>: Aerosols, sprays, and powders
  • USP <1601>: Nebulizer products
