Understanding the Neurofibromatosis Type 1 (NF1) experience and the priorities of individuals with NF1 and their caregivers for cognitive and social-emotional research.

BACKGROUND: Patient engagement is increasingly recognized as a valuable, essential aspect of Neurofibromatosis research given the unique experiences and morbidities associated with the diagnosis. Engaging patients and families can enhance the relevance, methodology, and feasibility of clinical trials. METHODS: A REDCap survey ascertaining information on NF-related morbidities, priorities, and interests in cognitive and social-emotional research, and willingness to participate in research was dispensed to 4,565 individuals consented to the Children's Tumor Foundation (CTF) Registry with NF1. This included children and adults with NF1 and parents/caregivers of children with NF1. RESULTS: 525 individuals fully completed the survey: 295 parents/caregivers (Mage child = 10.12, range = 3-24), 194 adults with NF1 (Mage = 45.73, range = 19-81), and 36 children with NF1 (Mage = 12.61, range = 10-17). Less than 10% of respondents have participated in cognitive research, while 42.4-49.5% indicated having sought opportunities for cognitive research. Most (79.4-82.4%) respondents reported that cognitive research is very/extremely important, with learning/academics and emotional functioning were priorities. Willingness to participate in research aligned with areas of importance. CONCLUSION: Analysis highlights that most survey respondents believe cognitive and social-emotional research is very important, but a relatively small number have participated. This finding may highlight poor dissemination of information of research opportunities to the broader NF community and limitations to access based on geography or other factors. Respondents indicate that learning/academic problems and emotional challenges to be research priorities. Continuing to engage patients and families with NF is expected to enhance the value and engagement in cognitive research.

Recommendations for Social Skills End Points for Clinical Trials in Neurofibromatosis Type 1.

OBJECTIVE: To review parent-report social skills measures to identify and recommend consensus outcomes for use in clinical trials of social deficit in children and adolescents (ages 6-18 years) with neurofibromatosis type 1 (NF1). METHODS: Searches were conducted via PubMed and ClinicalTrials.gov to identity social skills outcome measures with English language versions used in clinical trials in the past 5 years with populations with known social skills deficits, including attention-deficit/hyperactivity disorder and autism spectrum disorder (ASD). Measures were rated by the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) Neurocognitive Committee on patient characteristics, use in published studies, domains assessed, availability of standard scores, psychometric properties, and feasibility to determine their appropriateness for use in NF1 clinical trials. RESULTS: Two measures were ultimately recommended by the committee: the Social Responsiveness Scale-2 (SRS-2) and the Social Skills Improvement System-Rating Scale (SSIS-RS). CONCLUSIONS: Each of the 2 measures assesses different aspects of social functioning. The SSIS-RS is appropriate for studies focused on broader social functioning; the SRS-2 is best for studies targeting problematic social behaviors associated with ASD. Researchers will need to consider the goals of their study when choosing a measure, and specific recommendations for their use are provided.

Enhancing Neurofibromatosis Clinical Trial Outcome Measures Through Patient Engagement: Lessons From REiNS.

OBJECTIVE: As part of an evaluation of the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration patient representative program, we surveyed REiNS members to (1) identify facilitators and barriers to involving patient representatives and (2) understand whether and how involving patient representatives affected recommendations for clinical trial outcomes. METHODS: We administered an anonymous online survey to all REiNS members. Facilitators and barriers to patient representative involvement were solicited using a modified free listing technique; responses were inductively grouped into higher-order categories and ranked based on saliency score (Smith s). Open-ended questions assessed patient representative expectations for engagement, perceived benefits/costs of patient engagement, and patient representative contributions; responses were analyzed using conventional content analysis. RESULTS: A total of 63/172 (37%) members responded, including 18/30 (60%) patient representatives. Providing sufficient opportunities to meaningfully engage in research tasks and cultivating a respectful, inclusive atmosphere were key facilitators to patient representatives' satisfaction and ability to make an impact. Respondents perceived that patient representatives directly (through their input on research tasks) and indirectly (through effects on other stakeholders' knowledge and communication style) improved the organization's research, leading to selection of more meaningful, relevant, and feasible clinical trial outcome measures. Ongoing challenges to patient engagement include difficulty scheduling meetings and concerns about the level of scientific knowledge patient representatives needed to effectively engage. CONCLUSIONS: Involving patient representatives in REiNS improved perceived quality of neurofibromatosis clinical trial outcome measures. Negotiating sufficient opportunities to engage, fostering an inclusive atmosphere, and navigating time pressures are key to effective patient engagement.
