483 Warning Letters & How to Resolve Them

What is a 483 Warning Letter?

483 Warning Letters are delivered by the FDA to a company’s senior management team. These letters indicate critical regulatory violations identified after the conclusion of an inspection. A 483 Warning Letter is an escalation from a 483 observation.

FDA Investigators issue 483 Warning Letters if conditions or practices indicate that a device, drug, etc. is or could be corrupted and is a probable hazard to health and/or safety. A 483 Warning Letter can also be issued if 483 observations are not resolved.

Common reasons Warning Letters are issued include non-compliant written procedures, procedures not being followed appropriately, and inconsistencies and/or failures in investigations.

Warning Letters are public, they can be viewed by anyone including competitors and clients. Responding to a Warning Letter consumes resources and can severely delay time to market. It is imperative to respond quickly and take the appropriate steps to resolve the violations found.

How to Resolve a 483 Warning Letter

Create a Response Timeline & Identify the Root-Cause

The standard requirement to respond to a 483 Warning Letter is 15 days. However, if the FDA determines the violations are severe, the timeline can be escalated. Establish the steps to respond within the deadline.

Once the steps and timeline are established, it is paramount to perform a comprehensive review of all departments, procedures, and systems. Preform a root causes analysis to determine your corrective action plan. It is worth noting, there may be other unsatisfactory conditions that were not cited in the Warning Letter or 483 observations. Companies are required to take corrective actions on cited conditions and any related non-cited conditions that might exist as well.

Perform CAPAs & Establish Timelines

After your root cause is complete, draft your corrective and preventative action plans (CAPAs). Assign a CAPA owner(s) and perform CAPAs for each violation found. Follow a clear description of the issues (copy from the FDA).

It is important to act with urgency. However, ensure your timelines are realistic. It is vastly more important to adhere to the CAPA process and take the time needed to resolve issues, than it is to close issues prior to your initial submittal to the FDA. The FDA expects you to follow your CAPA process and take the time needed to resolve and prevent further issues.

Write and Submit an Initial Response

Your response should be comprehensive and demonstrate urgency and commitment to rectify all violations. Take responsibility, acknowledge all observations, and describe corrections.

Include copies of your CAPAs and include timelines including when and how often you will be sending updates to the FDA.

Evaluate Temporary Hiring Needs

It takes massive bandwidth to respond, rectify violations, and prepare for re-inspection. Hiring consultants is a great strategy to complete this process.

Consultants provide an outside perspective to remediate processes and resolve violations. They act as niche industry experts allowing companies to hire based on their specific needs.

For example, consider hiring a consultant(s) who specialize in 483 remediations. Consultants add credibility and can leverage their reputation with the FDA in your favor.

Utilizing an agency to hire expert consultants will help quickly increase your bandwidth and arm your company with industry experts, to successfully respond, correct violations, and pass re-inspection.

Follow Up with the FDA & Send a Final Response

Stay committed to your timelines stated in the initial response letter. Each update letter should include all the information from the initial response letter, along with updates on items that are completed.

Once all items are addressed, send a final response to the FDA that all violations have been addressed and resolved. From there, the FDA will respond by accepting your statement or will follow-up with additional questions.

Be prepared for Re-Inspection

Once the FDA has accepted your statement and completed corrections, it is likely there will be a follow-up inspection from the FDA.

It is important to note, these visits are typically unannounced. A thorough approach to rectify all issues from the 483 Warning Letter will ensure you will pass the inspection and avoid an escalation to a Consent Decree or otherwise.
