Summary

A Post-Market Prospective Clinical Investigation to collect PMCF data on the safety and performance of the Cefar URO device when using the preset program P4 (parameter setting: frequency 20Hz, pulse width 200μs) for the symptomatic treatment of urge incontinence in adults with overactive bladder in accordance with the approved labelling. The Cefar URO device features four pre-set programs (P1, P2, P3 and P4) and three custom programs. Although supporting data on the preset programs P1, P2, P3 are available for the clinically equivalent UROstim2 device, program P4 is unique to Cefar URO. Program P4 utilizes the parameters 20Hz and 200μs which are commonly reported in the literature for the stated indications but for which no data is available for the clinically equivalent UROstim2 device. The present study is therefore aimed to cover this data gap.

Detailed description

The objectives of this prospective study are to assess the performance and safety of Cefar URO when used at home by enrolled patients using the P4 program pre-set parameters i.e. frequency 20Hz, pulse width 200μs, for 12 weeks. Adult patients who require symptomatic treatment of urge incontinence and associated symptoms with overactive bladder (including refractory overactive bladder of idiopathic or neurogenic origin), will undergo Transcutaneous Posterior Tibial Nerve Stimulation with the Cefar URO device at home. The diagnosis of OAB is made by the Investigator on the basis of clinical symptoms in routine practice. The assessment of symptoms and quality of life of patients will be completed before treatment (Baseline) and after 6 and 12 weeks of treatment with the Cefar URO device. An additional assessment of the maintenance of symptoms and quality of life will be performed 4 weeks after end of the per protocol treatment. The tests used to assess symptoms and quality of life are and compliance with treatment are: 1. the Overactive bladder Questionnaire (OAB-q) SF 4 Weeks Recall (6-item Symptom Bother Scale and a 13-item HRQL Scale) 2. the 3-day bladder diary 3. A 6-point Likert scale to assess faecal incontinence (only in case patients experience faecal incontinence at baseline) 4. Compliance diary The following parameters setting (preset program P4) will be used for treatment of all enrolled subjects with the Cefar URO device: * frequency of 20Hz * pulse width of 200 μs * duration: 30 minutes per treatment. * treatment frequency: subjects will be recommended to have 7 treatment sessions per week for a total of 12 weeks (84 treatments total), and anyway no less that one treatment per week. The electrodes will be placed in the medial ankle as according to the device IFU. Patients will be asked to record each treatment session performed on the patient's diary, in order to assess compliance with the scheduled treatment plan. The subjects will be treated for a period of 12 weeks with the Cefar URO device as per the treatment protocol described above. After completion of the per protocol treatment period, the subjects will be followed up for an additional period of 4 weeks. During these four weeks, patients will be asked to continue performing the treatment according to their needs and according to the Investigator's instructions (Maintenance treatment protocol). No prescription about the number of treatments is imposed by the protocol during this period. The subjects will be evaluated at study site for 6 on site visits and 10 weekly phone contacts, as detailed in the study flowchart at the end of this section. Weekly follow-up phone contacts with the patients will be performed during the 12 weeks of the per protocol treatment with the exception of the weeks when an onsite visit is scheduled. One additional phone call will be performed during the exploratory long term 4 weeks follow up period (Maintenance period). These regular contacts serve to remind the patient to follow the treatment plan and to complete the self-reported questionnaires accurately. Additionally, at each phone contact patients will be asked to report if any issues/adverse events have been occurred since the last visit or phone contact. The regular phone contact with patients should help in keeping the adherence to the protocol and have a higher compliance to the treatment.
