Regulatory Class - Oct 24 Flashcards
Making changes to an NDA
Change to any condition of an approved application must be described fully and submitted in an NDA supplement or annual report
Submitted in the least burdensome notification
Must describe the changes in enough detail so the FDA can determine that the change was reported in the correct category
NDA Supplements with Clinical Data require a user fee.
Assessing the effects of the change
Need to do additional testing to assess whether identity, strength, quality, purity, or potency of drug product will be affected - with regard to safety and effectiveness
Chemical, physical, microbiological, biological bioavailability and/or stability profiles
Compare test results from pre- and post-change to determine if results are equivalent (not identical but within predetermined acceptable range)
NDA Supplement: Major Change
Substantial potential to have an adverse effect on identity, strength, quality, purity or potency of a drug product - relate to safety and effectiveness
Requires a prior approval supplement
Examples of Major Changes
Change in qualitative or quantitative formulation of drug product
Change requiring completion of studies to demonstrate equivalence
Change that may affect sterility
Change in manufacturing that may affect physical, chemical or biological properties of the drug substance
Contents of NDA Supplements
Detailed description of proposed change Drug product involved Manufacturing site affected Methods used and studies performed to assess the effects of the change Data from studies
Prior Approval Supplement - Expedited Review
Will happen in the interest of public health (ex. drug shortage)
Or if a delay in making change would present undue hardship to applicant (ex. changes due to catastrophic events)
NDA Supplement: Moderate Changes
Changes being Effected (CBE) supplement or
CBE 30 days supplement
Changes Being Effected in 30 Days
Must submit supplement more than 30 days prior to distribution of product with the change
Explain the basis for the change and identify date change will be made
(ex. change in container closure system that affect drug quality)
FDA can require approval before distribution or as sponsor to require more info
If FDA disapproves, the manufacturer must stop distribution
NDA Supplement - Changes Being Effected
Distribution can begin when FDA receives the supplement
If FDA disapproves, the manufacturer must stop distribution
NDA Supplement - Changes Being Effected - Examples
Changes in size or shape of container, change to add or strengthen contraindication or statement of drug abuse, changes in instructions to increase safe use
Minor Change
Minimal potential to have an adverse effect - relate to safety and effectiveness
Description of changes may be included in next Annual Report
Examples of Minor Changes
Deletion or reduction in an ingredient that effects color
Replacement of equipment with same design and operating principles
Change in size or shape of container - same number of dosage units
Extension of expiration dating based on data obtained from protocol approved in the NDA
Editorial or minor change in labeling
Change Info in Annual Report
Statement that the effects of the change have been assessed
Full description of the manufacturing and controls changes
Date each change was implemented
Data from studies/tests performed to assess effects of change
Labeling Changes
Need to make sure advertising and promo materials comply with new label
Comparability Protocol
Describes tests, studies, and acceptance criteria to demonstrate the absence of an adverse effect from a specified change or type of change
May reduce the supplement reporting category for those changes
If the proposed comparability protocol was not approved with the original application, it must be submitted as a Prior Approval Supplement
NDA Annual Report
Submitted within 60 days of the anniversary date of FDA’s approval - Use form FDA 2252
Summary of significant new info that might affect safety, effectiveness, or labeling
Quantity of drug product distributed in and outside the US
Labeling - changes since last report
CMC Changes
Nonclinical and Clinical Info (published and unpublished reports)
Status of postmarketing study commitments
PMA Supplement
Required for review and approval by FDA before making any change affecting the safety or effectiveness
Changes that don’t affect safety or effectiveness must be reported in Annual Report
Only info supporting the change is required to be included in the PMA supplement
Needs a section identifying each change and explaining the reason for the change
All require User Fees
Examples of Changes requiring PMA supplements
New indications for use Labeling or packaging changes Manufacturing facility or process changes Changes in sterilization procedures Changes to performance specification Changes to components Changes to principles of operation Extension of expiration date
Types of PMA Supplements
Panel-Track 180-Day Real-Time Special PMA 30-Day Notice
Panel Track Supplement
Most burdensome supplement
Significant change in design or performance or new indication for use and substantial clinical data are necessary
Changes in the device that may raise different types of safety and effectiveness questions
Changes in which there may be no accepted test methods for evaluating the issues of safety or effectiveness
These changes usually require significant changes in the labeling
Ex. different patient populations, different duration, remaining contraindications
180-day Supplement
Significant changes that affect safety and effectiveness
Changes in components, materials, design, specification, software, labeling
Change to different manufacturing facility
Usually require only new preclinical testing (and possibly limited confirmatory clinical data)
Ex. change to principles of operation; control mechanism; device design or performance; labeling; acceptance criteria
Real-Time Supplement
Minor changes that affect safety and effectiveness
Ex: change in design, software, labeling; changes that were expected with that device type and validated
The sponsor and FDA agree to interaction to jointly review the supplement and the FDA provides feedback immediately.
Can only do this if it’s a change in a single scientific discipline and a multidisciplinary review team is not necessary
Must have FDA approval to use this type of supplement
Special PMA Supplement
Changes being effected
Labeling or manufacturing change to reflect newly acquired information that enhances safety
Can implement change immediately if the supplement includes full explanation of the basis of the changes; the receipt is acknowledge by the FDA; specify the date on which the changes are being effected
Must be based on info not available during original submission; must have new scientific data; cannot use if change affects effectiveness.
Ex. add or strengthen contraindication or warning; enhance instruction for safe use; delete false and misleading indications; add additional assurance of purity, quality, identity, strength or reliability.
30-day notice
change to manufacturing procedure or method of manufacture; device incorporating change may be distributed 30 days after FDA receives the notice unless FDA notifies you that a 135-day supplement is required
Would not qualify for physical, chemical or performance changes
PMA Annual Report
Submitted annually from date of approval of original PMA
FDA reviews within 90 days of receipt; could say the report is complete or that they want more info or that changes were not appropriate for Annual Report
list all changes made since the last annual report, but those made in a supplement you provide less detail for
Parts of a PMA Annual Report
Cover letter (PMA number, device name, company identifiers, reporting period, approval date)
Manufacturing, design, labeling changes (identify changes, rational, validation, and date of implementation) Describe changes not reported in other supplements
Summary and bibliography of reports in scientific literature
Number of devices shipped or sold
