Gene therapy hope for babies with fatal muscle disease
NCT ID NCT07554924
First seen Jun 24, 2026 · Last updated Aug 27, 2026 · Updated 3 times
Summary
This early-phase trial tests a gene therapy called SKG0201 in 11 infants with spinal muscular atrophy (SMA) type I, a severe muscle-weakening disease. The therapy uses a harmless virus to deliver a working copy of the missing SMN1 gene. The study aims to see if it is safe and can improve survival and motor skills.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SKG0201 (gene therapy using a harmless virus to deliver a working SMN1 gene)
- What this could lead to
- If successful, this could provide a one-time treatment that improves motor function and survival in infants with SMA type I.
- What could go wrong
- This is an early, small trial (11 infants) testing safety and dosing. Gene therapy carries risks like immune reactions or liver issues, and it may not work for all.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Type I SMA, defined by bi-allelic mutations in the SMN1 gene. 2. Clinical history and signs are consistent with type I SMA, such as hypotonia, delayed motor function development, and poor head control. 3. On the day of administration, the age of the subjects do not exceed 180 days after birth. Exclusion Criteria: 1. Pulse oximetry \< 96% saturation at screening while the patient is awake or asleep without any supplemental oxygen or respiratory support. 2. Weight-for-age below the 3rd percentile for the same sex and age based on WHO Child Growth Standards. 3. Active viral infection. 4. In the presence of other severe infections or diseases that require systemic anti-infection treatment. 5. Known allergy to prednisolone, other glucocorticoids, or SKG0201's excipients. 6. Clinically significant abnormal laboratory values prior to administration. 7. Previously used Zolgensma or other SMA gene therapy drugs, or currently participating in other SMA clinical studies on therapeutic drugs. 8. Having previously undergone major surgery or expected to undergo major surgery during the study assessment period.
