What this trial studies

This clinical trial investigates the efficacy and safety of recombinant human fibroblast growth factor 1 (ES135) for patients diagnosed with mild-to-moderate carpal tunnel syndrome (CTS). Participants will be randomly assigned to receive either the ES135 injection or a placebo, with the injection performed under ultrasound guidance. The primary outcome will be measured using the Boston Carpal Tunnel Syndrome Questionnaire, while secondary outcomes will include pain assessment, electrophysiological studies, and imaging of the median nerve over a six-month period. The study aims to evaluate the potential regenerative effects of ES135 on nerve function and symptom relief in CTS patients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-80 with a confirmed diagnosis of mild-to-moderate carpal tunnel syndrome lasting more than three months.

Not a fit: Patients with severe carpal tunnel syndrome or those who have had recent treatments for CTS may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a novel, non-surgical option for alleviating symptoms and improving function in patients with carpal tunnel syndrome.

How similar studies have performed: Previous studies have shown positive outcomes with similar regenerative approaches in nerve injuries, suggesting potential for success in this trial.
