Intranasal AAV9-PHP.eB Gene Therapy in Cerebral Palsy (CP) & Hypoxic Ischemic Encephalopathy (HIE)

Sponsor: Healing Hope International

Summary

This international study, organized by Healing Hope International, is an observational registry designed to collect real-world data on participants living with chronic hypoxic ischemic encephalopathy (HIE) who receive an emerging intranasal gene therapy based on the AAV9-PHP.eB viral vector. The investigational therapy delivers a panel of 15 restorative genes that support brain repair, reduce inflammation, promote myelination, and improve neural communication. It is administered intranasally in one or three sessions by participating international clinical teams. Because the therapy is already being offered abroad, this registry does not assign treatment but instead follows participants who have received it as part of their existing medical care. The GEN HOPE Study aims to understand how this gene therapy affects movement, cognition, spasticity, and seizure frequency over time. Families and clinicians will share outcomes such as changes in gross motor function (GMFM-66/88), cognitive assessments (Bayley or WISC tests), and quality-of-life measures. Information on safety, laboratory results, MRI findings, and caregiver-reported experiences will also be collected. By combining data from multiple countries, the registry seeks to evaluate whether this novel gene based approach can meaningfully improve daily function and comfort for participants with chronic HIE. Results will guide future clinical trial development and help define safe and effective standards of care for regenerative neurologic therapies.
