Experimental gene therapy targets rare muscle disease in first human test
NCT ID NCT05876780
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tests a single-dose gene therapy called SRP-9003 in 6 people with limb girdle muscular dystrophy type 2E/R4, a rare genetic muscle-weakening disease. The main goals are to check safety and see if the therapy can produce the missing beta-sarcoglycan protein in muscle. Both ambulatory and non-ambulatory participants are included.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SRP-9003 (a gene therapy given as a single IV infusion)
- What this could lead to
- If successful, this could point toward a treatment that restores the missing protein in muscle cells, potentially slowing or stopping muscle weakness in LGMD2E/R4.
- What could go wrong
- This is a very early, small phase 1 trial with only 6 people. It primarily checks safety and protein levels, not whether it improves strength or daily life. Gene therapies can cause immune reactions or other side effects.

Inclusion Criteria: * Cohort 1 only: Ambulatory per protocol specified criteria. - Cohort 2 only: Non-ambulatory per protocol specified criteria and 4 to 50 years of age. * Possesses 1 homozygous or 2 heterozygous pathogenic and/or likely pathogenic β-sarcoglycan gene Deoxyribonucleic acid (DNA) (SGCB) gene mutations based on documented clinical findings. * Ability to cooperate with muscle testing. Exclusion Criteria: * Presence of any other clinically significant illness or medical condition, including cardiac, pulmonary, hepatic, renal, hematologic, immunologic, neuromuscular (other than LGMD2E/R4), or behavioral disease, or infection or malignancy or concomitant illness or requirement for chronic drug treatment that in the opinion of the Investigator creates unnecessary risks for gene transfer or a medical condition or extenuating circumstance that, in the opinion of the Investigator, might compromise the participant's ability to comply with the protocol required testing or procedures or compromise the participant's wellbeing, safety, or clinical interpretability. * Exposure to gene therapy, investigational medication, or other protocol-specified treatment within the protocol specified time limits. * Any contraindication to use of corticosteroid. Note: Other inclusion or exclusion criteria could apply.
