    Rare Disease Clinical Trials in Pediatric Populations: Lessons Learned

    by Traci Fulton on November 23, 2021 — 10 minute read

    Pediatric rare disease trials affect caregivers too

    Sponsors are likely to encounter compounding complexities when running pediatric rare disease trials.

    Individually, rare disease and pediatric clinical studies present noteworthy challenges, but together, they can tie logistical knots that impact families and cause costly delays. With more than 150 successful rare disease clinical trials supported, including several pediatric indications, this article outlines our top lessons learned and offers advice 15 years in the making.

    Rare diseases affect nearly 300 million people globally and most of them are children.1,2 

    In pediatric hospitals, beds are regularly filled with children battling a rare disease—approximately one third of whom will not live to see their 5th birthday.3 With an average time to diagnosis of six to eight years,4 high mortality rates, and no clear progression nor established standard of care, the margin for uncertainty in research is zero. 

    Participation in a clinical study can be a difficult ask, and these children are often severely ill. Managing the side effects of investigational products, transporting children to sites for visits, and running labs or assessments can create an overwhelming environment for everyone involved. For sponsors, these challenges are compounded by the increasing intensity of competition in study recruitment and gaining consent amidst heavily restricted travel. 

    innovation in pediatric rare disease trialsThe influx of companies exploring the rare space, together with the growing demand for improved patient-centricity is rapidly changing traditional study logistics, opening the door for innovative and outside-the-box strategies to drive enrollment and reduce the burden of participation.
    Competition and cost make patient-centricity an essential strategy in rare disease pediatric research.

    One obvious yet inescapable hurdle of rare disease pediatric research is the small pool of patients from which to recruit. With more and more choices available, families sit firmly in the driver’s seat. Variables like geography, study design, and trial goals are important factors that contribute to people’s willingness to enroll. While some of these variables may not be within a sponsor’s control, there are ways to make studies easier and more appealing to potential participants.

    • Educational videos: These immensely powerful tools help to ease feelings of uncertainty giving caregivers the information necessary to feel comfortable with the prospective therapy’s mechanism of action, the study’s requirements, and what potential outcomes are expected. 
    • Study branding:  Marketing is the most important way in which sponsors can raise awareness of an upcoming study. When well-executed, information-seeking parents and caregivers will proactively inquire about enrollment criteria and share promising findings within trusted online circles.  
    • Study portals: Among the many factors affecting a patient’s experience is the transfer of information. Portals streamline data sharing, helping to mitigate the disruption of household routines due to study participation.  
    • Concierge services: When in-person appointments are required, travel can be a sore subject. The special needs of very ill children make access to travel agents and seamless reimbursement a real difference-maker in this population’s decision-making. 

     

    Participating sites may also be affected by a pediatric rare disease study.

    Adding a complex trial on top of the already-taxed resources of most study sites can be a battle. In addition to the personnel requirements, beds, machines, or even respirators are required to meet the needs of these very (often terminally) ill children. Experience shows us that employing strategies to minimize the burden can help encourage sites to participate. Examples include: 

    • Providing inclusion and exclusion cards in addition to standard recruitment and engagement materials, as well as a laminated schedule of events for easy use in clinical settings  
    • Pocket protocols, visit checklists, and a study reference manual, together with Frequently Asked Questions, provide at-a-glance information and greater time efficiencies 
    • CRO-led trainings and streamlined communication pathways—like identifying centralized points of contact or outlining meeting cadence before study initiation—help to streamline study-related work 

    As rare disease pediatric patients are frequently immune-suppressed, remote care, telemedicine, and in-home nursing visits have shown to further reduce the efforts of on-site staff. During COVID-19, the adoption of decentralized clinical trials surged, and the outcomes have been largely favorable, demonstrating positive potential for specific populations. 

    The nature of these study populations may require patients to cross state or even country lines. Understanding and mapping the regulatory environment of each site as it relates to patient consent is critical both to study success and efficient patient enrollment.
    Consent and assent in pediatric rare disease clinical trials.

    The greater incidence of travel limitations is changing the way consent can be obtained. Currently, the only alternative to in-person consent is via independent physician consent in countries or verbal consent by relatives where these strategies are approved.  Due to the widespread impact of COVID-19, new guidance is being issued daily by the FDA, EMA, and other regulatory agencies to speed-up consent-related delays. Choosing a CRO experienced in managing consent in this changing environment is key to fast-tracking enrollment and study start.  

    Managing emotions plays a tremendous role in a rare disease pediatric study’s success.

    Kids will be kids and parents…parents. Remember, enrolling a child into a clinical trial can offer hope—if not for a cure today, for one that helps future patients—but until then, it is a burden. Children experience a rollercoaster of emotions ranging from fear and isolation in unfamiliar surroundings to the inconvenience in accommodating study schedules and site visits. Caregivers too can be anxious or even suspicious.  

    Through our experience working with child participants in rare disease studies, we’ve identified several study adaptions that can make study participation easier for everyone. 

    • Families should only be contacted by people they trust: Familiar physicians or an advocacy group are ideal for reaching out and the communication should always be tailored to the audience. 
    • Do not expect caregivers to “get it” right away: Avoiding medical jargon, asking questions to confirm their understanding, and providing ample time for discussions about the study and the child’s health helps build trust. 
    • Streamline study visits when possible: Short visit windows help parents who are taking time off work, managing transportation issues, and securing the extra help that may go in to moving a child. 
    • The perspectives gained by putting oneself in the caregiver’s shoes provide invaluable insights. Focusing on the holistic elements surrounding enrollment helps to build trust, show empathy, and reduce the emotional toll of study participation. This, in turn, creates a differentiated environment that is more attractive to families and increases the chances of enrollment and a timely study start.
