Spinal Cord Injury, Urinary Bladder, Overactive

Brief summary

The aim of this study is to continue following participants who have received EG110A during five years to know how it is tolerated in humans, any side-effects it may cause and what might be an effective dose over five years. All participants who have received at least one dose/injection of EG110A in a previous clinical study of EG110A will be asked to roll-over to this long-term follow-up study upon either early discontinuation from, or completion of, that study.

Detailed description

The objective of this long-term follow-up study is to continue following participants who have received EG110A for safety, and to observe long-term efficacy via a disease-specific quality of life questionnaire, time to participant request for alternative treatment, and locally-evaluated urodynamics. This study aims to identify any potential long-term risks and will capture any delayed adverse events (AEs) in participants following the last study visit of the preceding study. Additionally, it will allow the Sponsor to further understand the long-term effectiveness of EG110A in this patient population.
