Smart AFO and 5-Azacitidine to Enhance Mobility in Children With Cerebral Palsy

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Cerebral Palsy

In brief

This is an intervention study to investigate the impact of a smart ankle-foot orthosis (AFO) on mobility outcomes in children with Cerebral Palsy. Participants will complete a three phase protocol including 6-weeks of at home training with the smart AFO. Participants will also have the option to participate in a randomized control trial to investigate the impact of 5-Azacitidine combined with the smart AFO to further effect mobility outcomes.

You may qualify if…

• Diagnosis of cerebral palsy classified as Gross Motor Function Classification System (GMFCS) levels I to III
• Between 8 and 17 years and 8 months of age at the time of enrollment/consent. Participants that will turn 18 during the course of the study will not be included as pausing the at-home protocol until re-consenting is possible could interfere with intervention results.
• Stable medical condition as determined by the investigator.
• Adequate caregiver support to be able to participate in training and assessment sessions for the duration of the study, at the discretion of the PI.
• Height/weight/BMI between the 5th - 95th percentile of children with cerebral palsy
• Able to walk for at least 6 minutes (assisted or unassisted)
• Able to understand and follow simple directions
• Able to safely fit into a device configuration and tolerate assistance without knee hyperextension while walking
• At least 20 degrees of passive ankle plantar flexion range of motion
• Physician approval for participation

You may not qualify if…

• Knee extension or ankle dorsiflexion contractures greater than 15 degrees
• Immunodeficiency or hematologic condition
• Allergy to AZA or mannitol
• Plans to receive a vaccine within 30 days of the planned AZA or placebo injection to take place at week 5
• Pregnancy
• Orthopedic surgery on the lower limbs completed in the prior 12 months
• New implanted device (e.g., baclofen pump) and/or active intrathecal medication titration that may affect muscle spasticity
• Botulinum toxin treatment within 3 months preceding enrollment unless given approval by the study physician
• Severe osteoporosis unless given approval by the study physician
