Safety and Efficacy of TSHA-102 in Pediatric Females With Rett Syndrome (REVEAL Pediatric Study)

Conditions

Rett Syndrome Neurodevelopmental Disorder MECP2

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The REVEAL Pediatric Study is a multi-center, Phase 1/2 open-label, dose-escalation and dose-expansion study of TSHA-102, an investigational gene therapy, in pediatric females with Rett Syndrome. The safety, tolerability, and preliminary efficacy of two dose levels will be evaluated. The study duration is up to 6 years.

Official Title

A Multicenter, Open Label, Randomized, Dose-Escalation and Dose-Expansion Study of the Safety, Tolerability, and Efficacy of a Single Intrathecal Administration of TSHA-102, an AAV9-Delivered Gene Therapy, for the Treatment of Pediatric Females With Rett Syndrome

Standard Ages:CHILD

Inclusion Criteria	Exclusion Criteria
* Participant has a confirmed diagnosis of classical/typical Rett Syndrome with a documented mutation of the MECP2 gene that results in loss of function. * Participant is between ≥5 to ≤8 years of age at the time of consent. * Participant must be up to date with all relevant local vaccination requirements, with last vaccination dose received at least 42 days prior to the start of the immunosuppression regimen. * Participant's parent/caregiver must be willing to allow participant to receive blood or blood products for the treatment of an AE if medically needed.	* Participant has another neurodevelopmental disorder independent of the MECP2 gene loss of function mutation, or any other genetic syndrome with a progressive course. * Participant has a history of brain injury that causes neurological problems. * Participant had grossly abnormal psychomotor development in the first 6 months of life. * Participant has a diagnosis of atypical Rett syndrome. * Participant has an MECP2 mutation that does not cause Rett syndrome. * Participant requires non-invasive and invasive ventilatory support. * Participant has contraindications for IT administration of TSHA-102 or lumbar puncture procedure, other medical conditions, or contraindications to any medications required for IT administration. * Participant has acute or chronic hepatitis B or C infections.
