ABCs of NMOSD 701. University of Rochester NMO-Health Index Study

Krissy Dilger of SRNA spoke with Matt Rathbun and Charlotte Engebrecht from the University of Rochester Center for Health and Technology about the Neuromyelitis Optica Spectrum Disorder-Health Index (NMOSD-HI) study, which aims to develop and validate an NMOSD-specific patient-reported outcome survey for use in clinical trials and routine care [02:25]. They explained that existing measures are often adapted from multiple sclerosis and may not reflect NMOSD patients’ unique experiences [04:38]. They shared phase one insights from interviews with 15 individuals showing multi-system impacts [09:51]. They described eligibility for the current anonymous survey (adults 18+ with NMOSD, aquaporin-4 positive or negative, in the US, Canada, EU, UK, or Australia) and noted prior participants can join later phases [13:22]. You can learn more about the study here: https://redcap.link/nmo-hi Questions can be sent to Matt and Charlotte: Matthew_Rathbun@urmc.rochester.edu Charlotte_Engebrecht@urmc.rochester.edu Matt Rathbun, BA, graduated from Nazareth University in May of 2025 and is currently pursuing his Master of Public Health degree at Nazareth University. At the University of Rochester Center for Health + Technology (CHeT), he works as a Human Subject Research Specialist, where he coordinates translational research studies focused on the lived experiences of individuals living with rare diseases. This work supports the development and validation of disease-specific PRO measures that capture aspects of disease burden most meaningful to patients. Matt’s interests center on strengthening the relevance, inclusivity, and equity of clinical research. He aims to ensure that clinical research more accurately reflects the real-world impact of disease on patients’ lives. He also works to advance more equitable and patient-centered approaches to treatment evaluation in rare disease communities. Charlotte Engebrecht, BS, is a graduate of Hobart and William Smith Colleges and a current Master of Science in Clinical Investigations student at the University of Rochester. She serves as a Clinical Trials Project Specialist at the University of Rochester Center for Health + Technology (CHeT), where her work centers on the development and validation of patient-reported outcome (PRO) measures for rare diseases. Charlotte conducts research that is grounded in a commitment to elevating the patient voice as a central pillar of clinical research. Patient-reported outcomes offer critical insight into how diseases and treatments truly impact daily life. She is particularly passionate about ensuring that these perspectives are not only included, but prioritized, in the design and evaluation of clinical trials. Her work focuses on rare diseases, with a specific interest in neuromyelitis optica spectrum disorder (NMOSD), where traditional clinical endpoints often fail to capture the full burden of illness. By integrating patient-centered measurement tools into therapeutic development, Charlotte aims to advance more meaningful and responsive approaches to evaluating new treatments. 00:00 Welcome 02:25 Study Overview 04:38 Why Patient Voices Matter 06:16 How the Study Works 08:29 Who Can Participate 09:51 Phase One Findings 13:22 Join the Survey 15:43 Wrap Up
