RECRUITING

A Novel, Regulated Gene Therapy (NGN-401) Study for Females With Rett Syndrome

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

This study will evaluate the efficacy and safety profiles of the investigational gene therapy, NGN-401, in females with typical Rett syndrome.

Official Title

A Baseline-Controlled, Open-Label, Multicenter, Single-Arm, Pivotal Study to Evaluate the Efficacy, Safety, and Tolerability of NGN-401 in Subjects With Rett Syndrome (Embolden)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:3 Years
Sexes Eligible for Study:FEMALE
Accepts Healthy Volunteers:No
Standard Ages:CHILD, ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Females who are between the ages of ≥4 and ≤10 years for Arms 1 and 2 (Arms closed). Females who are ≥11 years of age or older for Arm 3 (Arm closed). Females who are ≥3 for Arm 4, the pivotal cohort.
  2. * Diagnosis of typical Rett syndrome with a documented disease-causing mutation in the methyl-CpG-binding protein 2 (MECP2) gene
  3. * Current anti-epileptic drug regimen has been stable for at least 12 weeks
  4. * Participant must be in the post-regression stage
  5. * Participant and caregiver should reside within a 2-hour drive of the study center for at least 3 months following treatment
  6. * Participant must have never taken trofinetide or have taken trofinetide and discontinued due to tolerability, lack of efficacy, or other reasons. Following NGN-401 dosing, trofinetide may be initiated after a specified time period and with the support of the treating clinician.
  1. * Normal or near normal hand function
  2. * Has a current clinically significant condition other than Rett syndrome
  3. * Presence of a concomitant medical condition that precludes intracerebroventricular administration, or use of anesthetics or immune suppression needed for study related procedures
