Friedreich Ataxia
Conditions
Brief summary
The goal of this clinical trial is to evaluate the safety and tolerability of nomlabofusp (CTI-1601) in adolescents and children with Friedreich's ataxia (FRDA).
Detailed description
This is a randomized, double-blind, placebo-controlled study evaluating a weight-based dose of nomlabofusp versus placebo in adolescents and children with FRDA. The study will consist of at least two cohorts with at least 12 to 15 participants in each cohort. Participants will be dosed once daily (QD) for 7 days.
Interventions
Nomlabofusp is a recombinant fusion protein provided in a sterile, preservative-free buffered solution for subcutaneous injection intended to deliver human frataxin, the protein deficient in Friedreich's ataxia.
The placebo is a sterile, preservative-free, clear liquid for subcutaneous injection.

Eligibility
Inclusion criteria
1. Subject has genetically confirmed diagnosis of FRDA manifested by homozygous GAA repeat expansions, with repeat sizing (if available) included on the diagnosis report. 2. Male or female subjects ≥ 2 to \< 18 years of age at screening. 3. Subjects must weigh ≥ 10.0 kg. 4. Subject must be able to traverse a distance of 25 feet with or without some assistive device (e.g., cane, walker, crutches, self-propelled wheelchair) and meet the following requirements: 1. Be able to sit upright with thighs together and arms crossed without requiring support on more than 2 sides; 2. Be able to transfer from bed to chair independently or with assistance if, in the opinion of the investigator, the degree of physical disability does not result in undue risk to the subject while participating in the study; and 3. Perform basic age-appropriate daily care, such as feeding themselves and personal hygiene, with minimal assistance.
Exclusion criteria
1. Subjects who are confirmed as compound heterozygous (GAA repeat expansion on only 1 allele) for FRDA. 2. Subject has any condition, disease, or situation, including a cardiac condition or disease, that in the opinion of the investigator could confound the results of the study or put the subject at undue risk, making participation inadvisable. 3. Subjects currently receiving or having received omaveloxolone within 30 days prior to Screening.
