What this trial studies

This observational study aims to assess the long-term safety of NUCEIVA, a treatment for moderate-to-severe glabellar lines, in a real-world clinical setting. Approximately 750 patients will be enrolled across 20 sites in the UK and EU, receiving an initial treatment of 20 Units of NUCEIVA. Patients may receive up to 6 treatments over an 18-month period, although further treatments are not mandated by the study protocol. The study will collect safety data to better understand the effects of NUCEIVA in everyday practice.

Who should consider this trial

Good fit: Ideal candidates are adults under 65 with moderate to severe glabellar lines who experience significant psychological impact from their appearance.

Not a fit: Patients with certain medical conditions, such as myasthenia gravis or those currently participating in other interventional studies, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety profile of NUCEIVA, enhancing patient confidence in its use.

How similar studies have performed: Previous studies on similar botulinum toxin treatments have shown positive safety profiles, suggesting that this approach is supported by existing evidence.
