MUSE TBI · AAV HIE · IVIG · Neurorehab
Sponsor: Healing Hope International
Prospective Observational (no intervention administered)
Ages 6–75 with chronic Traumatic Brain Injury (TBI)
MUSE (Multilineage-differentiating Stress-Enduring) stem cell infusions received outside the U.S.
12 months
MUSE cells are a specialized subset of mesenchymal stem cells with neuroregenerative properties. Participants independently elect to receive MUSE cell infusions through international clinical programs. The study captures real-world evidence on neurological function, quality of life, activities of daily living, and adverse events.

International Observational Study
Children with chronic Hypoxic Ischemic Encephalopathy (HIE) / Cerebral Palsy
Intranasal 15-Gene AAV9-PHP.eB therapy administered through international programs
Intranasal administration
GEN-HOPE evaluates a novel intranasal delivery approach using AAV9-PHP.eB, an adeno-associated viral vector carrying 15 therapeutic genes, in children with chronic HIE-related neurological injury. The study tracks neurological outcomes, developmental milestones, and safety data over time.

Observational Study
Long COVID patients undergoing intranasal IVIG treatment
Intranasal Intravenous Immunoglobulin (IVIG) — administered intranasally through international programs
Neurological and immune outcomes
Intravenous immunoglobulin (IVIG) is an immunomodulatory therapy with established use in neurological and autoimmune conditions. This observational study evaluates the safety and outcomes of intranasal IVIG delivery in Long COVID patients, capturing real-world data on symptom improvement, neurological function, and adverse events.

Observational Study
Patients with neurological conditions undergoing neurorehabilitation
Structured neurorehabilitation programs through international clinical programs
Functional recovery, quality of life, and neurological outcomes
This observational study evaluates the safety and outcomes of neurorehabilitation interventions in patients with neurological conditions. Data is collected on functional recovery, activities of daily living, quality of life, and adverse events over a structured follow-up period.
