Brief summary
To evaluate the efficacy and safety of subcutaneous nomlabofusp in adult and pediatric subjects with Friedreich's ataxia
Detailed description
This is a global, randomized, multi-center, placebo-controlled study to investigate the efficacy and safety of nomlabofusp in subjects with Friedreich's ataxia The main objectives of the study are to evaluate: * The efficacy of subcutaneous (SC) administration of nomlabofusp compared to placebo at Week 72; 1) on the Upright Stability Score (USS) Subscale E of the Modified Friedreich's Ataxia Ratings Scale (mFARS), or 2) mFARS total score (Region specific objective) * The efficacy of SC administration of nomlabofusp compared to placebo at Week 72 on the Clinical Global Impression of Severity (CGI-S) score * The safety and tolerability of SC administration of nomlabofusp
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
Key Inclusion Criteria: Subjects who meet all of the following criteria are potentially eligible for study participation: 1. Subject must provide genetically confirmed FRDA diagnosis report and is homozygous for GAA repeat expansions documented on the genetic diagnostic report, with repeat sizing (if available). 2. Subject must complete 1 trial at Screening and 1 trial at Day -1 of the T25-FW test, using their customary assistive device (e.g., cane, 2 canes/crutches \[Canadian crutches\], wheeled walker/rollator or canine assistance) if needed. Each trial must be completed within 3 minutes. 3. Subject must have the following at Screening and Day -1 per the following upright stability items from Module E of the mFARS: 1. Item #E1, Sitting Posture - no more than a maximum score of 2 2. Item #E2A, Stance Feet Apart - no more than a maximum score of 2 (average of 3 attempts) 4. Subject must have an mFARS score ≥ 20 and \< 60 at Screening and Day -1. 5. Subject must have a Functional Staging for Ataxia score of 4 or less at Screening. 6. Subject demonstrates sufficient dexterity and visual acuity to prepare and self-administer SC injections of study drug daily (QD) or has an identified caregiver who will be trained and committed to prepare and administer the injections. 7. Subject has a Screening HbA1c ≤ 7.0%. 8. If the subject is taking permitted concomitant medication(s), subject must have been on a stable dose and frequency of medication(s) over the past 28 days prior to initiation of Screening. Subjects taking niacin and resveratrol must have been on a stable dose and frequency for 90 days prior to initiation of Screening and subjects taking omaveloxolone must have been on a stable dose and frequency for 1 years prior to initiation of Screening.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in Upright Stability Score (USS) subscale E of modified Friedreich's Ataxia Rating Scale (mFARS) at Week 72 (Region-specific) | Baseline, Weeks 12, 24, 36, 48, 72 | Number - The USS has a score range from 0 to 36. Lower scores mean less impairment and higher scores mean greater neurological impairment. |
| Change from baseline in the total modified Friedreich's Ataxia Rating Scale (mFARS) at Week 72 (Region-specific) | Baseline, Weeks 12, 24, 36, 48, 72 | Number - The mFARS has a total score range from 0 to 93. Lower scores mean less impairment and higher scores mean greater neurological impairment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in the Clinical Global Impression-Severity (CGI-S) score at Week 72 | Baseline, Weeks 12, 24, 36, 48, 72 | Number - The CGI-S is a 7-point scale. Lower scores mean less impairment and higher scores mean greater neurological impairment. |
