INOPASE - Performance and Safety Study of a Personalised SNM System

Официальное название

Feasibility and Safety Study to Evaluate the Sensing and Stimulation Performance of a Personalised Sacral Neuromodulation (SNM) System for Refractory Overactive Bladder

Обзор

The goal of this clinical trial is to learn whether a new sacral neuromodulation (SNM) system (INO-SNM-01) can safely and effectively sense bladder nerve activity and provide stimulation to help manage symptoms of refractory overactive bladder in adult women aged 18-70 who have not responded to standard treatments. The main questions it aims to answer are: * Is there a clear relationship between bladder nerve activity and patient-reported urgency sensations? * Can targeted stimulation based on bladder nerve activity reduce overactive bladder symptoms? * Is the INO-SNM-01 System safe to use? Researchers will not use a comparison group in this study. Instead, all participants will receive the investigational device to see if it works as intended. Participants will undergo surgery to have a temporary trial lead implanted near the sacral nerve and spend up to 2 days in hospital for monitoring and testing to assess the device sensing and stimulation capabilities. Up to 10 participants will take part in this first-in-human feasibility study at a single site in Australia.

• Evaluation of whether timely stimulation by the INO-SNM-01 device correlates with 'Loss of desire to urinate' as measured by the Feeling Indicator [Срок оценки: From device implantation to the end of treatment 2 days]
• Evaluation of whether timely stimulation by the INO-SNM-01 device shows a reduction in bladder afferent nerve activity response when providing stimulation compared to no stimulation [Срок оценки: From device implantation to the end of treatment 2 days]
• Evaluation of whether timely stimulation by the INO-SNM-01 shows a reduction in bladder pressure (cm H2O) measured by a urodynamics monitor [Срок оценки: From device implantation to the end of treatment 2 days]
• Evaluation of whether timely stimulation by the INO-SNM-01 device shows an increase in urinary volume (mL) during each urination cycle as measure by a urodynamics monitor. [Срок оценки: From device implantation to the end of treatment 2 days]
• Evaluation of whether timely stimulation using the INO-SNM-01 device shows an increase in time between urination cycles (minutes) as reported by the Feeling Indicator [Срок оценки: From device implantation to the end of treatment 2 days]
