    Good morning, good afternoon, and good evening Compliance Rockstars, Clinical Researchers, Ethics Educators, and Investigators from around the globe!

    It’s hard to believe that January is coming to a close. It feels like just yesterday folks were sending their New Year wishes. It felt as though I was reviewing countless study submissions. I prefer to be on my toes than idle!

    ICYMI, TikTok went dark on January 18, 2025 only to return on January 20, 2025. You can read about my insights here:

    Now, back to today’s post. On January 6, 2025 the final version of the ICH GCP E6(R3) guidelines. Whether you’re a novice to clinical research (like me) or an expert, this is a HUGE deal. The last revision for ICH GCP E6(R2) was back in November 2016. Without writing this post, I could guess that there are significant differences. But I don’t like to guess…I like to know and understand why.

    For background, I primary review IRB studies related to social, behavioral, and education research (SBER). I am extremely interested in learning more about clinical research ethics and clinical trials in general.

    Therefore, I would like to thank Adnan Shaikh for his willingness to review and co-author this post!

    In this post, we plan to describe in detail the differences between the E6(R2) version and the E6(R3) version. As a general disclaimer, these are our own interpretations of these guidelines. If you have any questions about these guidelines, you should always consult with your institution.


    Tasha Mohseni’s POV on General Guideline Differences

    Aside from document length, the table below summarizes the general differences between the guidelines:

    What Did ChatGPT Have to Say About The Guideline Differences?

    As you all know from my Show and Tell: How to Write a Clear SBER Protocol post, I have my own personal ChatGPT account.

    I can’t even quantify how long it took me to summarize the general differences for the two documents. Though this was interesting to review, I found it difficult to sift through the information. This might be because I haven’t had exposure in this area. I likely should have completed the GCP CITI training course to provide a foundation. Alas, here we are!

    Out of curiosity and efficiency, I decided to upload both guidelines to ChatGPT and asked for itemized differences. Below is a complete response from ChatGPT:

    “To provide a detailed, itemized comparison of the ICH E6(R2) and ICH E6(R3) documents, I will identify key differences across major sections and topics in both documents. This will include updates, additions, and revisions. Here’s an itemized list based on their content:

    These itemized differences highlight the evolution of clinical trial guidelines from E6(R2) to E6(R3), reflecting advancements in technology, trial design, and ethical considerations. Let me know if you want a deeper analysis of any specific section!”

    At face value, this seems to be an impressive comparative analysis.

    You might be wondering why I said the word “seems”.

    I say this because I am acknowledging that I am not a subject-matter expert. I can’t even say that I have direct experience with this other than reading the guidelines themselves. I can’t necessarily validate if ChatGPT assessed the information correctly. I could have done more iterative prompting to receive an even more detailed response…but for what? This is why it is so important to have the expertise to verify the information is correct. Whether you become knowledgeable or collaborate with someone who has the expertise. Let’s see what Adnan Shaikh has to say about ChatGPT’s analysis!

    Adnan Shaikh’s POV on the ChatGPT Analysis (in his own words)

    Hey everyone! I hope you’re enjoying reading Tasha’s content. Here’s my take on the ICH GCP E6(R2) versus ICH GCP E6(R3).

    The adoption ICH GCP E6(R3) introduces a transformative update to the principles and practices of clinical research:

    • The ICH GCP E6(R2) guidelines were more focused
      • They adhered to the protocol and followed the traditional approach in clinical trial studies, that has an impact of โ€œone size fits all”
    • While ICH GCP E6(R3) is more modern and advanced approach for clinical trial, it encourages โ€œfit for purposeโ€
      • Which means that proportionality and risk-based approaches focus on the quality of clinical trials
        • This is critical and fundamental to the safety of participants and the reliability of participants results

    I humbly recognize that I am not as expert and that I am still learning

    However, to summarize the overall concept of ICH GCP E6(R3), it focuses on the following:

    • Emphasize proportionality risk-based approach,
    • Incorporates innovative technologies, and
    • Promotes adaptability to modern clinical trial design.

    In the recent times, AI is claimed to be one of the best tools in helping with clinical research.

    Now, I would like to share my POV on ChatGPT.

    It is helpful in many ways, for example:

    • Preparing document with little to no grammatical errors,
    • Providing information on particular drug molecules, and
    • Providing information on ICH GCP guidelines

    When I prompted ChatGPT about the difference between ICH GCP E6(R2) vs ICH GCP E6(R3), I received the following graphical explanation:

    Image of ChatGPT’s graphic representation of the differences between ICH GCP E6(R2) and ICH GCP E6(R3)

    As you can see, this further illustrates my point that ICH GCP E6(R3) highly focuses on modern adaptation. By implementing this concept, it can provide more flexibility in clinical research studies. In the era of AI and emerging technologies, itโ€™s important to adapt the modern techniques in clinical trials. It is also criticial to note that this must be done without compromising confidentiality. We must adhere to ethical standards for the responsible use of these emerging technologies.

    I am expressing my sincere gratitude to Tasha for involving me in this post. I ‘m looking forward to working with her on future projects!

  • FDA Artificial Intelligence (AI) Guidance Highlights

    FDA Artificial Intelligence (AI) Guidance Highlights

    Good morning, good afternoon, and good evening IRBers, clinical research educators, and investigators from around the world!

    I hope everyone had a great first of full week back to work! Now, I can officially say, back to the grind. I should be used to how busy the start of the semester is with outreach training efforts. I was also busy reviewing submissions. We typically see an increase in submissions around this time since it is the start of Spring semester.

    Besides being busy with work, I was also working on the Show-and-Tell Series of blog posts. You can read about the series here:

    Advertisements

    Well, I wasn’t the only one busy this week. The FDA went on a guidance posting frenzy! Below is a list of guidance documents relevant to IRB and clinical research that were issued between Monday, January 6, 2025 – Friday, January 10, 2025:

    Though all these guidance documents should be reviewed, I plan to only deep dive into the following guidance documents:

    You may be wondering why I’m solely focusing on these two guidance documents.

    I’ll tell you why I’m into AI!

    • AI can optimize productivity. I canโ€™t tell you how many times this has saved me. For people like me who have trouble reading long documents, AI is great for summarizing key concepts. Of course, I will read all documents in their entirety. However, itโ€™s nice to have a general idea of what I plan to read. This way, if there are any concepts or terms Iโ€™m unfamiliar with, I can simply look them up. Then, when Iโ€™m reading the document in full, I wonโ€™t have to waste time looking up terms and concepts.
    • AI can help you be creative. I canโ€™t wait to share a post related to this! Before I think about automating a task, I ask ChatGPT if itโ€™s possible. Then, with my skills Iโ€™ve acquired over the years, I can attempt to act on my efficiency idea. I also love the DALL-E aspect. This is great for visual folks. I especially love to have DALL-E create flowcharts or diagrams. This helps me understand complex topics (such as the ethical codes in human subjects research).
    • AI can be used in any facet. Whether youโ€™re a writer, an artist, in IT, or even compliance, AI can be helpful anywhere! I will say that itโ€™s important to make your audience aware when AI was used. I always love to give credit where credit is due. I feel that AI can even make the least creative personโ€ฆa creator.

    Though I sound pro-AI, I do see there are downsides.

    • Privacy and confidentiality are major concerns. This likely goes without saying, but I will say it anyway. Compliance personnel such as myself likely know you shouldnโ€™t place any personal information into ChatGPT. Well, others may not know this. What about ways to withdraw your data? Can you do that in ChatGPT? I know there is a way to export data that was entered into the tool via your ChatGPT settings. But can ChatGPT unlearn data that has been withdrawn? Iโ€™m not sure, but I hope to learn more about this.
    • Machine learning bias is real. For those who may not be familiar with machine learning, this is a subset of AI. There isnโ€™t actual programming (e.g., with Python). It learns from datasets and makes inferences based on patterns. This is why it is called โ€œmachine learningโ€ because the tool learns over time. I feel this is GREAT for a highly specific function (such as a customer service chatbot). But what about when AI is being used for biomarker analysis or drug development? How can we ensure that we are applying the Belmont principle of Justice (subjects must be fairly selected)? How do we ensure we are fairly selecting datasets that are representative of the population of interest?
    • Compliance professionals are in an arms race in how to regulate the rapid use of AI in research. Again, this likely goes without saying it. You can probably start calling me โ€œCaptain Obviousโ€ now. Even as I learn about AI, it is hard to keep track of everything thatโ€™s going on. I follow federal agencies for guidance documents or if strategic plans are released discussing the ethical uses of AI. To me, the problem seems to be that everyone is developing their own guidance documents and best practices. It seems to me that something like this should have a best practice standard that agencies can adopt. I plan to learn about the EU AI Act in further detail as this seems like a great start. I recently completely GDPR trainings and felt this regulation really covered everything. We desperately need something like this in the United States.

    In this post, I plan to highlight key takeaways from these lengthy AI guidance documents (90 pages total).

    Then, I plan to analyze the documents even further as the request for comment is due Monday, April 7, 2025.

    Let’s make our voice count TOGETHER!


    Considerations for the Use of Artificial Intelligence to Support Regulatory Decision-Making for Drug and Biological Products

    Per the FDA, this guidance provides recommendations to sponsors and other interested parties on the use of AI to produce informations or data intended to support regulatory decision-making regarding the safety, effectiveness, or quality of drugs. Though I am not an expert in drug development, I will say that I have intermediate understanding of AI. Letโ€™s see what the FDA has to say.

    The guidance provides a risk-based credibility assessment framework that may be used for establishing and evaluating the credibility of an AI model for a particular context of use (COU).

    The COU defines the specific role and scope of the AI model to address a specific question. As a former auditor, I also appreciate that the FDA has defined the word โ€œshouldโ€. The definition of โ€œshouldโ€ means that the FDA recommends actions within this guidance, but they arenโ€™t required. I remember carefully reviewing policies for words like โ€œshouldโ€, โ€œshallโ€, or โ€œmustโ€. Itโ€™s important for institutions to define this as well. This way, when folks are reviewing their institutionโ€™s policy or guidance, they know what is required versus what is recommended.

    A Risk-Based Credibility Assessment Framework

    This is a 7-step process:

    • Step 1: Define the question of interest that will be addressed by the AI model.
    • Step 2: Define the COU for the AI model.
    • Step 3: Assess the AI model risk.
    • Step 4: Develop a plan to establish credibility of AI model output within the COU.
    • Step 5: Execute the plan.
    • Step 6: Document the results of the credibility assessment plan and discuss deviations from the plan.
    • Step 7: Determine the adequacy of the AI model for the COU.

    Okay, so we know the steps. What do we do for each of these steps?

    Step 1 should describe the specific question, decision, or concern being addressed by the AI model. For step 2, the description of the COU should describe in detail what will be modeled and how model outputs will be used. It should also be notated on whether other information will be used in conjunction with the AI modelโ€™s output to answer the question of interest determined in step 1. Examples of other information include animal studies and/or clinical human research studies. In step 3, model risk is assessed by two factors: model influence and decision consequence. Model influence, like it sounds, compares data derived from the AI model to other evidence used to inform the question of interest in step 1. Decision consequence is the significance of an adverse outcome resulting from an incorrect decision concerning the question of interest in step 1. To appropriately assess these components of model risk, subject-matter expertise is strongly advised.

    Step 4 describes what information should be in your credibility assessment plan. Below is a summarized list of information that should be considered:

    • Describe the datasets used for training and tuning the AI model and which model development activities were performed using these datasets
    • Describe how the development data have been or will be collected, processed, annotated, stored, controlled, and used for training and tuning the AI model
    • Describe how the development data is fit for the COU
    • Describe whether the development data are centralized
    • Describe how the AI model was trained
    • Specify if a pre-trained model was used
    • Describe the use of ensemble methods
    • Explain any calibration of the AI model
    • Describe the quality assurance and control procedures of computer softwares and how version changes were tracked (as well as code verification)
    • Describe the applicability of the test data to the COU to minimize data drift
    • Describe the agreement between the model prediction and the observed data
    • Provide rationale for the chosen model evaluation method
    • Describe any model limitations and biases

    For step 5, discussing the credibility assessment plan with the FDA prior to execution may be helpful. The last section of the document describes early engagement options s with the FDA. Step 6 should involved documenting the results and deviations from steps 1-4. Once this is complete, you can proceed to step 7. Step 7 is where you determine if the AI model is appropriate for the COU. Finally, the document concludes with life cycle maintenance of the credibility of the AI model output in certain COUs. This can be referred to as the management of changes to an AI model (whether incidentally or deliberately).

    Artificial Intelligence-Enabled Device Software Functions: Lifecycle Management and Marketing Submission Recommendation

    Per the FDA:

    This draft guidance, when finalized, will represent the current thinking of the FDA on this topic.

    Though this document will represent FDAโ€™s thoughts, I appreciate FDAโ€™s flexibility in approaches towards these recommendations. So long as the applicable statutes and regulations are met and it has been discussed with the FDA, you can use an alternative approach. The guidance provides recommendations on the contents of marketing submissions for devices that include AI-enabled device software functions including documentation and information that will support FDAโ€™s review. Similar to the previous guidance, the FDA defines the word โ€œshouldโ€ as โ€œsuggestedโ€ or โ€œrecommendedโ€. Nowโ€ฆletโ€™s get into this document!

    The FDA promotes a total product life cycle (TPLC) approach to the oversight of medical devices. You can read more about TPLC here: Total Product Life Cycle for Medical Devices. They also discussed the recent efforts made such as the 10 tenets of Good Machine Learning Practice (GMLP). The document further defines terminology used by the FDA versus the general AI community. For example, using the term โ€œvalidationโ€ to represent โ€œtrainingโ€ or โ€œtuningโ€ should be avoided in medical device marketing submissions. Instead, the word โ€œdevelopmentโ€ should be used. The FDA Digital Health and Artificial Intelligence Glossary โ€“ Educational Resource provides a compilation of commonly used AI Terms and how the FDA defines them.

    The next few sections within this guidance are what the FDA recommends including in marketing submissions. Each section provides a reason as to why it must be included, what must be included, and where to include it. Below is a general outline of what is recommended for submission:

    General Outline for Marketing Submissions
