What Does an End of Phase 1 (EOP1) FDA Meeting Involve?

 An End of Phase 1 (EOP1) meeting with the U.S. Food and Drug Administration (FDA) is a crucial milestone in the drug development process. This meeting provides an opportunity for sponsors to discuss the results of Phase 1 clinical trials and obtain FDA feedback before proceeding to Phase 2. In this article, I discuss some of the key components of an EOP1 meeting:

  1. Meeting Request and Background Information:

    • Sponsors initiate the process by requesting an EOP1 meeting with the FDA. This request should include a comprehensive background on the investigational drug, its mechanism of action, and the Phase 1 trial design.

    • An EOP1 meeting is considered a Type B meeting, which has a 14 day response time for the FDA to respond to the request on whether it is granted or not. The FDA guidance is that the meeting should take place within 60 days of the request.

According to FDA guidance, the meeting request must include the following information:

  • The proposed meeting format (i.e., face to face, teleconference/videoconference, or WRO).
  • The date the meeting background package will be sent by the requester.
  • A brief statement of the purpose of the meeting. This statement should include a brief background of the issues underlying the agenda. It also can include a brief summary of completed or planned studies and clinical trials or data that the requester intends to discuss at the meeting, the general nature of the critical questions to be asked, and where the meeting fits in overall development plans. Although the statement should not provide the details of trial designs or completed studies and clinical trials, it should provide enough information to facilitate understanding of the issues, such as a small table that summarizes major results.
  • A list of the specific objectives or outcomes the requester expects from the meeting.
  • A proposed agenda, including estimated times needed for discussion of each agenda item.
  • A list of requested FDA attendees and/or discipline representative(s). Note that requests for attendance by FDA staff who are not otherwise essential to the application’s review may affect the ability to hold the meeting within the specified time frame of the meeting type being requested. Therefore, when attendance by nonessential FDA staff is requested, the meeting request should provide a justification for such attendees and state whether or not a later meeting date is acceptable to the requester to accommodate the nonessential FDA attendees.

    The meeting request should include the following information:

    • The application number (if previously assigned).
    • The product name.
    • The chemical name, established name, and/or structure.
    • The proposed regulatory pathway (e.g., 505(b)(1), 505(b)(2)).
    • The proposed indication(s) or context of product development.
    • Pediatric study plans, if applicable.
    • Human factors engineering plan, if applicable.
    • The meeting type being requested (i.e., Type A, Type B, Type B (EOP), or Type C).
    • Combination product information (e.g., constituent parts, including details of the device constituent part, intended packaging, planned human factors studies), if applicable.
    • Suggested dates and times (e.g., morning or afternoon) for the meeting that are consistent with the appropriate scheduling time frame for the meeting type being requested (see Table 2 in section VI.B., Meeting Granted). Dates and times when the requester is not available should also be included.
    • A list of proposed questions, grouped by FDA discipline. For each question there should be a brief explanation of the context and purpose of the question

    1. Meeting Package Preparation:

      • Prior to the meeting, sponsors compile a meeting package that includes detailed information on the Phase 1 trial, such as protocols, patient demographics, safety data, and preliminary efficacy data. The package is often referred to as a "Briefing Book" or "Briefing Package".

      • According to FDA guidance, the meeting package is submitted to the FDA no later than 30 days before the scheduled date of the meeting and should be organized according to the proposed agenda. The meeting package should be a sequentially paginated document with a table of contents, appropriate indices, appendices, and cross references. It should be tabbed or bookmarked to enhance reviewers’ navigation across different sections within the package, both in preparation for and during the meeting

      • Meeting packages generally should include the following information, preferably in the order listed below:

    • The application number (if previously assigned).
    • The product name.
    • The chemical name, established name, and/or structure
    • The proposed regulatory pathway (e.g., 505(b)(1), 505(b)(2)).
    • The proposed indication(s) or context of product development.
    • The dosage form, route of administration, and dosing regimen (frequency and duration).
    • Pediatric study plans, if applicable.
    • Human factors engineering plan, if applicable.
    • Combination product information (e.g., constituent parts, including details of the device constituent part, intended packaging, planned human factors studies), if applicable.
    • A list of all individuals, with their titles and affiliations, who will attend the requested meeting from the requester’s organization, including consultants and interpreters.
    • A background section that includes the following:
      • A brief history of the development program and relevant communications with the FDA before the meeting
      • Substantive changes in product development plans (e.g., new indication, population, basis for a combination), when applicable
      • The current status of product development
    • A brief statement summarizing the purpose of the meeting and identifying the type of milestone meeting, if applicable.
    • A proposed agenda, including estimated times needed for discussion of each agenda item.
    • A list of the final questions for discussion grouped by FDA discipline and with a brief summary for each question to explain the need or context for the question. Questions regarding combination products should be grouped together.
    • Data to support discussion organized by FDA discipline and question. Protocols, full study reports, or detailed data generally are not appropriate for meeting packages; the summarized material should describe the results of relevant studies and clinical trials with some degree of quantification, and any conclusion about clinical trials that resulted. The trial endpoints should be stated, as should whether endpoints were altered or analyses changed during the course of the trial.

    1. Agenda Setting:

      • The sponsor and the FDA collaborate to set the meeting agenda. This includes outlining specific topics for discussion, such as safety and efficacy findings, plans for Phase 2, and any questions or concerns.

    2. Meeting Presentation:

      • During the EOP1 meeting, sponsors provide a structured presentation summarizing Phase 1 trial data. This includes a detailed analysis of safety profiles, dose-response relationships, pharmacokinetics, and pharmacodynamics.

    3. Safety Assessment:

      • A significant portion of the meeting is dedicated to safety. Sponsors must address any adverse events observed during the Phase 1 trial and propose strategies for managing them in future studies.

    4. Efficacy Discussion:

      • Sponsors present any preliminary efficacy data, if available. The FDA evaluates the clinical relevance and potential impact on future trial design.

    5. Regulatory Strategy:

      • Sponsors should outline their proposed Phase 2 trial design and endpoints. The FDA provides input on the acceptability of these plans and may suggest modifications to enhance the trial's success.

    6. Questions and Clarifications:

      • Both parties engage in a dialogue to address questions, concerns, and recommendations. The FDA may offer guidance on specific issues, such as patient populations, trial duration, or endpoints.

    7. Next Steps:

      • The EOP1 meeting concludes with a discussion of the next steps. Sponsors should leave with a clear understanding of the FDA's feedback and any requested actions or additional data.

    8. Meeting Minutes:

      • Detailed meeting minutes are crucial. Sponsors are responsible for preparing these minutes, which should accurately capture all discussions and agreements reached during the meeting.

    9. Follow-up Actions:

      • Sponsors should promptly address any action items identified during the meeting and incorporate FDA feedback into their development plan for Phase 2.

    In summary, an End of Phase 1 meeting with the FDA is a pivotal point in drug development. It requires careful preparation, a thorough presentation of Phase 1 data, and a collaborative discussion with the FDA to ensure alignment on the path forward for Phase 2. Accurate documentation and timely follow-up are essential for a successful transition to the next stage of clinical development.

    What is an IRT System for a Clinical Trial?

    An Interactive Response Technology (IRT) system is a software system that is used to randomize patients to treatment arms and manage the supply chain of investigational drugs in a clinical trial. IRT systems are essential for ensuring the integrity and efficiency of clinical trials. 

    IRT systems work by automating the process of patient randomization and drug supply management. This helps to eliminate human error and bias. IRT systems also provide real-time data on patient enrollment and drug inventory, which can be used to make informed decisions about the trial.

    IRT systems are used in all phases of clinical trials, from Phase 1 to Phase 4. However, they are especially important for complex trials with multiple treatment arms and/or decentralized trial sites.

    Some examples of how IRT systems are used in drug clinical trials:

    • Randomizing patients to treatment arms: IRT systems can be used to randomize patients to treatment arms in a fair and unbiased manner. This is important for ensuring that the trial results are reliable and generalizable.
    • Managing the supply chain of investigational drugs: IRT systems can be used to track the inventory of investigational drugs at each trial site. This helps to ensure that the right drug is available to the right patient at the right time.
    • Monitoring patient safety: IRT systems can be used to monitor patient safety during the trial. For example, IRT systems can be used to track the occurrence of adverse events and to identify patients who are at risk of serious side effects.
    • Collecting data: IRT systems can be used to collect data from patients throughout the trial. This data can be used to analyze the safety and efficacy of the investigational drug.

    Some of the benefits of using an IRT system in a drug clinical trial include:

    • Improved data quality and accuracy: IRT systems automate the process of patient randomization and drug supply management, which helps to eliminate human error and bias. This results in improved data quality and accuracy.
    • Reduced risk of bias: IRT systems ensure that patients are randomized to treatment arms in a fair and unbiased manner. This helps to reduce the risk of bias in the trial results.
    • Increased efficiency: IRT systems automate the process of patient randomization and drug supply management, which can save clinicians and trial staff a significant amount of time.
    • Improved transparency: IRT systems provide real-time data on patient enrollment and drug inventory. This data can be used to make informed decisions about the trial and to keep stakeholders informed of the trial's progress.


    Overall, IRT systems are a valuable tool for conducting drug clinical trials. They can help to improve the quality, accuracy, and efficiency of trials, while also reducing the risk of bias.

    User Acceptance Testing (UAT) for IRT and EDC Systems in Pharmaceutical Data Management

    In pharmaceutical data management, the efficient and accurate execution of clinical trials is paramount. To ensure the seamless functionality of Interactive Response Technology (IRT) and Electronic Data Capture (EDC) systems, User Acceptance Testing (UAT) plays a pivotal role (yes, that's a lot of acronyms in one sentence...welcome to biotech/pharma). In this article, I discuss what UAT entails for IRT and EDC systems, emphasizing its importance in the biotech and pharmaceutical industry.

    Understanding User Acceptance Testing (UAT): User Acceptance Testing (UAT) is a systematic and crucial phase in the development and implementation of IRT and EDC systems within clinical trial data management. It is the final step before these systems go live in a clinical trial, where end-users validate their functionality, usability, and compliance with predefined requirements. Here's an overview of UAT in this context:

    1. Objective and Scope:

      • UAT aims to ensure that IRT and EDC systems meet the specific needs and expectations of the end-users, including clinical investigators, data managers, and other stakeholders.
      • The scope of UAT encompasses verifying that the system is error-free, user-friendly, and capable of supporting the clinical trial's data collection and management processes.

    2. Preparation:

      • Prior to UAT, a detailed test plan is developed, outlining test cases, scenarios, and acceptance criteria.
      • Test data, reflecting real-world scenarios, is often prepared to simulate the actual trial environment.

    3. Execution:

      • End-users, who are usually sponsor employees well-versed in clinical trial processes, perform UAT.
      • They execute predefined test cases, interact with the system, and assess its functionality against acceptance criteria.

    4. Validation:

      • During UAT, users validate various aspects, including:
        • Data entry and retrieval processes in EDC systems.
        • Randomization and drug supply management in IRT systems.
        • System performance under different scenarios.
        • Compliance with regulatory requirements.

    5. Issue Reporting:

      • Users document any issues, anomalies, or discrepancies encountered during UAT.
      • These issues are reported to the development team for resolution.

    6. Regression Testing:

      • After issue resolution, regression testing may be performed to ensure that fixes have not introduced new problems.

    7. Sign-off:

      • Once all identified issues are resolved, users provide formal sign-off, indicating their acceptance of the system's readiness for production use.

    Importance of UAT in Pharmaceutical Data Management: User Acceptance Testing is paramount for several reasons:

    1. Quality Assurance: UAT serves as the final quality check, helping to identify and rectify any functional or usability issues before the system goes live.


    2. Regulatory Compliance: Ensuring that the system complies with regulatory requirements is essential for clinical trials' success and data integrity.


    3. User Satisfaction: UAT ensures that end-users are comfortable with the system, leading to smoother trial operations and more accurate data collection.


    4. Risk Mitigation: By identifying and addressing issues in a controlled testing environment, UAT reduces the risk of problems arising during the actual trial.

    In the complex area of clinical trial data management, User Acceptance Testing (UAT) for IRT and EDC systems is the final checkpoint before "go live" on a clinical trial. It is the bridge between system development and successful trial execution. UAT tests the system's functionality, compliance, and user-friendliness, so that pharmaceutical companies can conduct clinical trials with confidence, precision, and adherence to regulatory standards.
