Gene therapy hope for rare nerve disease enters first human tests
NCT ID NCT07180355
First seen Jun 24, 2026 · Last updated Aug 18, 2026 · Updated 5 times
Summary
This early-phase trial is testing a gene therapy called SGT-212 for Friedreich's ataxia, a rare genetic disease that damages the nervous system. Ten adults with the condition will receive the therapy through an injection into the brain and a vein. The main goal is to see if it is safe and tolerable over about 5 years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SGT-212 (a gene therapy using a harmless virus to deliver a working copy of the frataxin gene)
- What this could lead to
- If it works, this could point toward a treatment that slows or stops Friedreich's ataxia progression.
- What could go wrong
- This is a very early, first-in-human trial with only 10 people. It is designed mainly to check safety, not effectiveness. Gene therapies can have unexpected side effects, and it may not work at all.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Has history of FA symptom onset ≤25 years of age * Has a clinical and genetic diagnosis of FA * Has a staging score of ≥1 but \<6 on the Friedreich's Ataxia Rating Scale (FARS) Functional Disability Staging Score * Is willing to agree to the following rules for use of omaveloxolone (Skyclarys): 1. For a candidate who is currently taking omaveloxolone, has been on a stable dose for 12 weeks, expects to continue taking omaveloxolone at that dose throughout the study, and is willing to stop taking omaveloxolone at the direction of the Investigator or Sponsor's Medical Monitor if evidence of transaminitis or synthetic liver dysfunction is detected during the study 2. For a candidate who is not actively taking omaveloxolone, at least 12 weeks have passed since the last dose and the candidate agrees not to resume omaveloxolone during the 18-month period after SGT-212 infusion NOTE: The use of any other approved or investigational medicinal product for the treatment of FA should be discussed with the study team. Exclusion Criteria: * Antibodies against adeno-associated virus serotype 9 (AAV9) * Has a modified FARS (mFARS) score \<20 * Has a body weight ≤25 kilogram (kg) or has body mass index (BMI) ≥33 kg/m\^2 * Has a contraindication to endomyocardial biopsy (EMB) or cardiac catheterization * Is unable to undergo cardiac and brain MRI with contrast, including hypersensitivity to gadolinium contrast agent, presence of a non-MRI-compatible cardiac pacemaker, presence of a non-MRI-compatible implantable cardiac defibrillator, or physical condition (e.g., contractures) * Has uncontrolled diabetes as defined by a hemoglobin (Hb) A1c \>9% * Has participated in recent interventional clinical studies or received any investigational therapy administered within 3 months or 5 half-lives (whichever is longer) prior to Screening * Has received gene therapy at any time * Has contraindications to receiving corticosteroids * Has any contraindication to the surgical procedures involved with IDN infusion of SGT-212 * Has any known cardiac disease not related to FA including known obstructive coronary artery disease (CAD) * Other Inclusion/Exclusion criteria to be applied as per protocol.
