Requesting Post-Warning Letter Meetings

During an inspection, the US FDA may detect that the manufacturer has violated a significant number of regulations. These could be low-quality manufacturing processes, issues regarding product claims, and even incorrect directions for use. In this case, the FDA notifies the manufacturer of the same by way of a Warning Letter which, in addition to the violations, highlights the need for companies to correct these issues. In light of Warning Letters, the FDA unveiled a crucial document that provides guidance on navigating post-warning letter meetings. The release of this draft guidance marks a milestone in the implementation of the Generic Drug User Fee Amendments (GDUFA) III.

Overview of Post-Warning Letter Meetings

This draft guidance offers a comprehensive framework for drug (API/DMF) manufacturing facilities seeking to engage with the FDA in post-warning letter meetings. These meetings are designed to provide preliminary feedback on the corrective and preventive action (CAPA) plans implemented to address current good manufacturing practice (cGMP) deficiencies identified in warning letters. The guidance emphasizes that these meetings are not intended for application-related discussions, underscoring their primary purpose in aiding facilities to resolve inspection deficiencies.

Within the GDUFA III commitment letter, provisions were made for both post-warning letter meeting requests and re-inspection requests. However, the draft guidance specifically addresses the former, shedding light on factors facilities should consider when requesting these meetings. It also outlines the stringent performance goals set by the FDA, aiming to issue decisions for 50 per cent of eligible post-warning letter meeting requests within a mere 30 days of receipt, starting in the fiscal year 2024.

The Purpose of GDUFA and Its Reauthorizations

At its core, the GDUFA aims to streamline the approval process for generic drugs while upholding stringent quality standards. Stakeholders involved in the reauthorization of GDUFA emphasize the pivotal role of timely access to high-quality generic drugs as a cornerstone of their collective mission.

Post-Warning Letter Meetings: Timing and Circumstances

A key function of stakeholders in the drug manufacturing process is to understand the timing and circumstances under which Post-Warning Letter Meetings occur. Typically, these meetings take place six months or later after a facility responds to an FDA warning letter. However, stakeholders may request earlier meetings if they are deemed beneficial to the remediation process.

Eligibility Criteria for Meeting Requests

To initiate a Post-Warning Letter Meeting, facilities must meet specific eligibility criteria. These criteria include the facility’s compliance status, the payment of GDUFA facility fees, and the focus of the regulatory action on violations related to human drug manufacturing. Here, stakeholders play a critical role in ensuring that their facilities meet these prerequisites.

Meeting Request Submission

Stakeholders, primarily represented by the facility, parent company, or authorized legal representative, must submit a comprehensive meeting package. This package includes the Corrective and Preventive Action (CAPA) plan and supporting information that demonstrates the commitment to systemic remediation of deficiencies.

Timing of Meeting Request

Stakeholders must exercise caution in timing their meeting requests. Requests made within 15 working days of submitting a warning letter response should be separate from the initial response submission.

Preparing the Meeting Package

The meeting package’s effectiveness lies in its ability to describe key areas of interest and demonstrate reasonable progress towards remediation. It should include specific information pertinent to the discussion topics.

Assessing Meeting Requests

The FDA reviews meeting requests and may request additional information for clarification. The agency then decides whether to grant, deny, or defer the meeting, emphasizing its discretionary role.

Meeting Request Outcomes

Stakeholders must be prepared for various outcomes:

– If granted, the FDA schedules the meeting and notifies the facility.

– If denied, it may be due to an incomplete CAPA plan, insufficient progress, or ineligibility.

– In some cases, the FDA may defer the meeting in favour of a re-inspection, a crucial function of stakeholders.

Procedures for Conduct of Meetings

During meetings, stakeholders must adhere to specific procedures. These meetings, chaired by the FDA, generally last one hour and follow a recommended format, including introductions, remarks, presentations, discussions, and closing remarks.


The guidelines for implementing Post-Warning Letter Meetings underscore the collaborative effort of stakeholders including pharmaceutical companies and regulatory bodies. These meetings serve as a vital mechanism for addressing and monitoring the progress of facilities in remediating deficiencies cited in warning letters, ultimately ensuring the continued safety and efficacy of generic drugs in the market. Understanding and fulfilling the key functions of stakeholders is central to achieving this overarching goal.
