Agenda l.jpg
Agenda

  • Define Comparability Protocol (CP)

  • When can a CP be used?

  • CP Submissions

  • Content of CP submissions

  • Content of subsequent submissions

  • Summary


Comparability protocol cp l.jpg
Comparability Protocol (CP)

  • What is a CP?

    Described in 601.12(e)

    An applicant may submit one or more protocols describing the specific tests and validation studies and acceptable limits to be achieved to demonstrate the lack of adverse effect for specified types of manufacturing changes on the identity, strength, quality, purity, or potency of the product as they may relate to the safety or effectiveness of the product. Any such protocols, or change to a protocol, shall be submitted as a supplement requiring approval from FDA prior to distribution of the product which, if approved, may justify a reduced reporting category for the particular change because the use of the protocol for that type of change reduces the potential risk of an adverse effect.


Comparability protocol cp4 l.jpg
Comparability Protocol (CP)

  • What is a CP? (cont)

    • Submission option

    • Highly specific, well-defined plan for implementing a change in manufacturing

    • Demonstrate that change does not affect safety, identity, purity or potency


Comparability protocol cp5 l.jpg
Comparability Protocol (CP)

  • What is a CP? (cont)

    • Specific for the change and for the applicant

    • FDA will approve CP if change does not adversely affect product

    • Approval of CP may allow a reduced reporting category for future implementation of the specific change in the CP

      • Expedite interstate distribution of products

    • Not appropriate for all changes


Comparability protocol cp6 l.jpg
Comparability Protocol (CP)

  • When can a CP used?

    • Product manufactured using the change will meet approved product standards

    • Manufacturing process has been validated and all equipment has been qualified

    • Appropriate validated assays are available to detect effect of the change on the product

    • Implementation of single change in multiple locations operating under the same license using SOPs, forms, labels, etc. approved in CP


Comparability protocol cp7 l.jpg
Comparability Protocol (CP)

  • When should a CP not be used?

    • Broad plan covering any conceivable change

    • Change has potential to adversely effect product

    • Pre-specified acceptance criteria are not available to determine effect on product

    • Change results in newly defined product that is not licensed

    • Use of new manufacturing facility needing pre-license inspection

    • Change in process, equipment or facility that may need pre-approval inspection


Comparability protocol cp8 l.jpg
Comparability Protocol (CP)

  • CP Submissions

    • Submit as a PAS under 601.12(b)

    • May be combined with product manufacturing supplement

    • Once approved, CP must be implemented exactly as described in CP

    • If implementation deviates from CP, all future submissions for same change must be reported as PAS


Comparability protocol cp9 l.jpg
Comparability Protocol (CP)

  • CP Submissions

    • Future supplements reporting implementation of same change described in CP may be reported in reduced category specified in approval letter (eg, PAS to CBE30)

    • Supplements reporting implementation of CP should include information committed to in approved CP

    • Submit a new CP or a change to an existing approved CP as a PAS


Routine submission example l.jpg
Routine SubmissionExample

  • Applicant wants to implement Platelet Pheresis collection at 4 centers using instrument X

  • Implements at center #1

    • Develops SOPs; performs testing, validation, training, etc.

  • Submits supplement for center #1 as PAS

  • FDA approves implementation at center #1

    • Center #1 distributes product interstate after approval

  • Submits implementation at centers #2 - #4 as PAS

    • Distribute product interstate after approval


Comparability protocol cp example l.jpg
Comparability Protocol (CP)Example

  • Applicant wants to implement Platelet Pheresis collection at 4 centers using instrument X

  • Implements at center #1

    • Develops CP and SOPs; performs testing, validation, training, etc.

  • Submits CP and supplement for center #1 as PAS


Comparability protocol cp example12 l.jpg
Comparability Protocol (CP)Example

  • FDA approves CP and implementation at center #1

    • Approval letter states future implementation of CP may be reported as CBE30 and expected content

    • Center #1 distributes product interstate after approval

  • Submits implementation for centers #2 - #4 using approved CP as CBE30

    • Implementation must follow CP implementation plan

    • Distribute product interstate 30 days after FDA receives supplement


Comparability protocol cp13 l.jpg
Comparability Protocol (CP)

  • Contents of CP Submission

    • FDA form 356h

    • Cover letter

    • SOPs

    • Records and Forms

    • Product Quality Control Logs

    • Labeling

    • May reference previously approved SOPs, forms and labeling (include reference number)


Comparability protocol cp14 l.jpg
Comparability Protocol (CP)

  • Contents of CP Submission (cont)

    • Description of the change

    • Implementation plan, including description of training

    • Specific tests and validation protocols

    • Product acceptance criteria

    • Supportive data obtained from testing and validation

      • summary of validation and

      • 2 months QC


Comparability protocol cp15 l.jpg
Comparability Protocol (CP)

  • Contents of CP Submission (cont)

    • QC testing procedures, including sampling plan

    • Description of actions if acceptable results not achieved

    • QA program oversight

    • Request a CBE-30 downgrade for subsequent facilities


Comparability protocol cp16 l.jpg
Comparability Protocol (CP)

Subsequent Submissions Content

  • Cover Letter

  • Summary of Validation

  • 2 Months QC


Summary l.jpg
Summary

  • Comparability Protocol is a submission option

  • Specific change for manufacturing product

  • Requires full evaluation of potential impact of change on product

  • May allow future implementation of CP in a reduced reporting category – expedite interstate distribution


Summary18 l.jpg
Summary

  • CP must be implemented exactly as approved

  • Report any changes in approved CP

  • CP not appropriate for all types of submissions
