- 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).
- 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.
- Subject must have the following at Screening and Day -1 per the following upright stability items from Module E of the mFARS:
- Item #E1, Sitting Posture - no more than a maximum score of 2
- Item #E2A, Stance Feet Apart - no more than a maximum score of 2 (average of 3 attempts)
Show all 11Show fewer
- Subject must have an mFARS score ≥ 20 and < 60 at Screening and Day -1.
- Subject must have a Functional Staging for Ataxia score of 4 or less at Screening.
- 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.

- 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.
Who cannot join
- Subjects are excluded from the study if any of the following exclusion criteria are met:
- Subject who is confirmed as compound heterozygous (GAA repeat expansion on only 1 allele) for FRDA.
- Subject previously participated in a clinical trial involving nomlabofusp. Participation is defined as the subject having signed the informed consent for the study and received at least 1 dose of study drug (nomlabofusp or placebo).
- The subject has any condition, disease, or situation that could confound the results of the study or put the subject at undue risk, making participation inadvisable in the opinion of the PI.
- Women of childbearing potential who are pregnant (have a positive pregnancy test at Screening or Day -1), lactating, or planning to attempt to become pregnant during this study or within 90 days after the last dose of study drug (this includes male subjects with partners of childbearing potential who are attempting to become pregnant).

- Subject's use of biotin supplementation exceeds 30 μg/day, either as part of a multivitamin or as a standalone supplement, within 7 days prior to the first dose of study drug. Biotin supplementation ≤ 30 μg/day is permitted if taken at a stable dose and frequency for at least 28 days prior to the initiation of Screening and there is a commitment from the subject to maintain the biotin dose throughout the study (due to interference with assays).
- Subject receives medication that requires SC injection in the abdomen or thigh.
- Subject has a Screening ECHO left ventricular ejection fraction < 45%.
- Subject has a QTcF on an ECG as specified below:
- For subjects ≥ 12 and < 18 years of age, a male or female subject with a QTcF > 460 ms.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NomlabofuspDrug
Also called CTI-1601
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.
PlaceboDrug
Also called CTI-1601 Placebo, Nomlabofusp Placebo
The placebo is a sterile, preservative-free, clear liquid for subcutaneous injection.
| Study group | Role | What they receive |
|---|---|---|
| Nomlabofusp | Experimental | Daily subcutaneous injection of nomlabofusp for 72 weeks Receives: Drug: Nomlabofusp |
| Placebo | Placebo comparator | Daily subcutaneous injection of placebo for 72 weeks Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in Upright Stability Score (USS) subscale E of modified Friedreich's Ataxia Rating Scale (mFARS) at Week 72 (Region-specific)
Number - The USS has a score range from 0 to 36. Lower scores mean less impairment and higher scores mean greater neurological impairment.
Measured: Baseline, Weeks 12, 24, 36, 48, 72
Change from baseline in the total modified Friedreich's Ataxia Rating Scale (mFARS) at Week 72 (Region-specific)
Number - The mFARS has a total score range from 0 to 93. Lower scores mean less impairment and higher scores mean greater neurological impairment.
Measured: Baseline, Weeks 12, 24, 36, 48, 72
Secondary outcomes (1)
Change from baseline in the Clinical Global Impression-Severity (CGI-S) score at Week 72
Number - The CGI-S is a 7-point scale. Lower scores mean less impairment and higher scores mean greater neurological impairment.
Measured: Baseline, Weeks 12, 24, 36, 48, 72

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Nomlabofusp in people with Friedreich Ataxia and Friedreich's Ataxia, run by Larimar Therapeutics, Inc. at 4 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 9 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Larimar Therapeutics, Inc. (844-511-9056, medicalinfo@larimartx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in Upright Stability Score (USS) subscale E of modified Friedreich's Ataxia Rating Scale (mFARS) at Week 72 (Region-specific) (time frame: Baseline, Weeks 12, 24, 36, 48, 72). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07778836, which also lists 26 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Oct 2026.
