Key objectives of the initiative include:
Developing a step-by-step framework (PE Digital Roadmap) for implementing meaningful patient engagement in digital health
Clarifying the role of patients in designing and developing digital health solutions
Addressing challenges in digital health stakeholder alignment through the Stakeholder Expectations Matrix
Promoting transparency in patient involvement processes for digital health solutions

Findings
Cytokine Release Syndrome (CRS) is a common and potentially life-threatening adverse event of immunotherapies, particularly in Oncology, complicating patient care and increasing healthcare costs. Standard-of-care inpatient monitoring for CRS is manual, intermittent, costly, and restrictive, providing an incomplete view of the syndrome’s development and progression. The use of Digital Health Technologies (DHTs) for continuous, remote monitoring of vital signs (like heart rate, respiratory rate, skin temperature, SpO2, and activity) can capture early indicators of CRS up to two hours earlier than standard episodic monitoring. This ability to collect multivariate continuous data is valuable for informing robust model development for CRS risk prediction.

Recommendations
Investigators should deploy DHTs available today to monitor vital signs and symptoms currently observed in the hospital setting, but in an outpatient or home environment. The goal is to develop Early Warning Products that assess the probability of developing CRS, providing clinical decision support. Product developers should follow a strategic roadmap that outlines milestones for building products that are clinically relevant and commercially viable. Researchers should use a common set of digital clinical measures to gather high-quality datasets and ensure comparability across studies to build more robust predictive models. Predictive algorithms should be built on a robust reference measure for analytical validation and be clinically validated with sufficient data.

Regulatory Considerations
The resources are designed to help developers build products that are clinically appropriate, regulatory-acceptable, and commercially viable. Future regulatory submissions for CRS de-risking products will benefit from aligning with this industry-wide dialogue that is being built in collaboration with the FDA. Developing a robust CRS safety biomarker could enhance the safety profile of clinical trials, increase trial access, and streamline regulatory decision-making, possibly through a qualification pathway. Products that aim for a higher level of autonomy, such as a Diagnostic that redefines current CRS grading classes, may require very high clinical evidence and likely stringent regulatory review.

Findings
The goal of sDHT design is to create tools that are functional, intuitive, accessible, and enjoyable to use, moving beyond merely minimizing use-errors. Human-centered design (HCD) is the preferred term over user-centered design, emphasizing the impact on many user groups beyond just the end-users. "Users" encompass end-users (patients/participants), carepartners, clinicians, investigators, and administrators.

Recommendations
Developers of sDHTs should adhere to the following HCD principles:
Empathetic: Take time to deeply understand users' needs, behaviors, and emotions, capturing this in the use specification.
Holistic: Consider the entire end-to-end user journey, including hardware, software, accessories, packaging, instructions for use, and training.
Iterative: Employ an iterative approach to designing, prototyping, testing, and refining, using formative evaluations to identify use-errors and gather usability data, capturing this in the use-related risk analysis.
User-centric: Improve usability by capturing user feedback in real-world settings, gradually recruiting larger, more diverse samples that represent the intended use population.
Inclusive: Collaborate with individuals representing all user groups by hiring them as consultants or creating user advisory panels to influence design decisions (co-design).
Multidisciplinary: Ensure the development team includes colleagues from various disciplines to bring diverse perspectives and innovative solutions.

Regulatory Considerations
The document ties the HCD process to risk management and eventual validation by recommending that findings from formative evaluations (used to identify use-errors) be captured in a use-related risk analysis. The approach aligns with the principles of the overarching V3+ framework.

Findings
The clinical research ecosystem has longstanding diversity gaps, making targeted DEI strategies essential for equitable healthcare innovation.
Digital tools, including virtual visits, digital outreach campaigns, and AI-driven analytics, can increase access to trials for underrepresented populations.
Real-world data (RWD) and real-world evidence (RWE) help identify diverse participant pools and optimize recruitment strategies.
eConsent and educational resources improve patient engagement and retention by making clinical trials more transparent and accessible.
Trust-building measures, such as community partnerships and patient advocacy collaborations, are critical for long-term success in diversifying clinical trials.

Recommendations
Clinical trial sponsors should integrate digital tools at each stage of trial design to enhance participant diversity and reduce barriers to participation.
AI/ML and real-world data should be leveraged to identify, recruit, and retain diverse patient populations in a data-driven manner.
Digital engagement strategies, including social media outreach and mobile-friendly platforms, should be employed to improve awareness and accessibility.
Transparent communication, including clear eConsent processes and on-demand educational materials, should be prioritized to foster participant trust.
A comprehensive tracking system should be implemented to measure progress on diversity goals, ensuring accountability in clinical trial execution.

Regulatory Considerations
The FDA Diversity Plan requirement should be incorporated into clinical trial planning, with measurable targets for diverse participant inclusion.
Digital tools used for recruitment and engagement must comply with HIPAA, GDPR, and other privacy regulations to protect participant data.
The use of real-world evidence (RWE) in regulatory submissions should be expanded to demonstrate the efficacy of digital recruitment and retention strategies.
Standardized DEI reporting frameworks should be established to ensure regulatory bodies can assess the impact of diversity initiatives in clinical research.
Clinical trials utilizing digital tools should align with decentralized clinical trial (DCT) regulatory guidance to maximize accessibility and equity.

Key objectives of the initiative include:
Enhancing patient engagement and experience in clinical trials
Providing practical guidance for implementing patient-facing technologies
Addressing regulatory considerations and challenges
Facilitating collaboration among sponsors, sites, patients, and technology vendors

Findings
The development of this standardized questionnaire highlights a critical gap in clinical research: the lack of a consistent method for collecting participant feedback. It implicitly finds that understanding the patient experience is essential for addressing issues like high dropout rates and patient burden. The tool's detailed sections suggest that factors from communication and scheduling to technology usability and visit burden are key determinants of a participant's trial experience.

Recommendations
The resource strongly recommends that sponsors and research sites proactively gather structured feedback directly from study participants. It advises using this tool to identify specific pain points in trial design and execution. The underlying recommendation is to adopt a more patient-centric and human-centered approach by integrating participant feedback into the continuous improvement of clinical trial protocols and operations, ultimately boosting recruitment and retention.

Regulatory Considerations
While not a formal regulatory guidance document, the tool supports the principles of patient-focused drug development (PFDD) encouraged by regulatory bodies like the FDA. Collecting data on the patient experience can help demonstrate that a trial's design and conduct minimizes undue burden and is ethically sound. This feedback can be a valuable component of submissions, illustrating a commitment to patient centricity and potentially improving the assessment of a trial's overall quality and integrity

Findings
Sponsors must weigh the study benefits of PTs against potential burdens such as usability challenges, frequent reminders, or the need for connectivity and device maintenance.
Factors such as geography, socioeconomics, cultural practices, and technical literacy must be addressed to ensure PT accessibility across diverse patient populations.
Sponsors need to protect patient privacy by adhering to data protection standards and ensuring informed consent materials clearly communicate how data will be used and stored.
Effective maintenance, training, and 24/7 support systems for patients and sites are critical to ensure smooth operation and minimize disruptions.
Providing value to participants, such as progress feedback or gamification elements, can improve the patient experience and adherence.

Recommendations
Design Patient-Centric Materials: Simplify patient-facing materials, tailoring them to low health and technical literacy levels, and ensure patient input is incorporated during the design phase.
Identify and address geographic, socioeconomic, and cultural barriers to technology adoption to ensure inclusivity.
Offer multi-format training for patients and caregivers, provide troubleshooting guides, and ensure 24/7 multilingual technical support.
Safeguard patient data and inform patients of all potential risks associated with PTs. Develop backup plans for device failures or power outages.
Assess how PTs affect daily living, including comfort, usability, and the time required for setup and routine use, to minimize intrusion.

Regulatory Considerations
Ensure adherence to GDPR, HIPAA, and other relevant data protection laws. Clearly communicate privacy and data use details in consent forms.
Validate PTs for safety and suitability in the target population and ensure compliance with regulatory standards for medical devices.
Ensure that consent forms clearly describe PT functionality, benefits, and limitations in accessible language.
Global Adaptability: Account for regional laws, infrastructure limitations, and language requirements to ensure PT compatibility and regulatory compliance across geographies.

Findings
Digital measures must align with patient-defined meaningful aspects of health to ensure relevance and impact.
Continuous patient engagement is essential to identify meaningful concepts, validate measures, and refine endpoints.
The proposed framework—MAH, COI, Outcome, Endpoint—helps structure the development process, ensuring alignment with patient priorities.
Existing tools like the 6-minute walk test lack specificity and meaningfulness for many patients, highlighting the need for patient-centered digital alternatives.
Regulatory guidance emphasizes the importance of meaningful, patient-focused endpoints in clinical trials to support treatment evaluation and labeling claims.

Recommendations
Continuously involve patients in defining MAHs, COIs, outcomes, and endpoints to ensure relevance and usability.
Use the MAH-to-Endpoint framework to systematically develop measures that align with patient needs and clinical goals.
Select outcomes that demonstrate a clear relationship with MAHs and COIs, supported by patient and clinical validation.
Work collaboratively with patient advocacy groups, regulators, and researchers to harmonize development efforts and prioritize meaningful measures.
Ensure technology choices are driven by patient needs and clinical relevance, not the capabilities of available tools.

Regulatory Considerations
Ensure digital measures comply with regulatory expectations for meaningfulness, clinical relevance, and evidence generation.
Provide robust evidence linking MAHs, COIs, outcomes, and endpoints to support regulatory submissions.
Validate Endpoints Rigorously: Demonstrate that digital endpoints reliably reflect patient outcomes and provide value in clinical trial contexts.
Include Statistical Plans: Define how endpoints will be analyzed, ensuring alignment with trial protocols and regulatory frameworks.
Use patient-reported anchors to validate the clinical meaningfulness of changes in digital measures.
