"This patent is a testament to our team's dedication and expertise in developing cutting-edge solutions to address unmet medical needs. We look forward to leveraging this technology to advance our pipeline and bring new therapies to patients worldwide."

The granting of this patent in China marks a significant step forward for Versameb as it continues to expand its global footprint and protect its innovative technologies. The company remains committed to advancing its research and development efforts to bring transformative RNA-based therapies to market.

About VMB-100

VMB-100 is an intramuscular mRNA treatment encoding human IGF-1, aimed at treating stress urinary incontinence (SUI). It shows promise for sustained muscle regeneration after short-term use. Preclinical studies revealed that VMB-100 boosts IGF-1 expression in human muscle cells and accelerates urinary sphincter muscle regeneration in animal SUI models. The FDA recently cleared the IND application for VMB-100, and Versameb is currently planning a Phase 2a dose-ascending study for moderate SUI in women, scheduled for 2025.

About Stress Urinary Incontinence

Stress urinary incontinence is a common condition among women, characterized by the involuntary leakage of urine during physical activities due to a weakened urinary sphincter muscle. SUI is the most common form of urinary incontinence, affecting 86% of incontinent women. Overall, it is estimated that more than 30% of adult women worldwide suffer from SUI.

Despite its widespread prevalence, there are currently no approved pharmacological therapies for SUI available in the United States. Current standard of care protocol includes short-term solutions like pelvic floor therapy or a highly invasive surgical procedure in which a sling is permanently implanted into the urethra or bladder neck.
