Summary

Tibial nerve stimulation (TNS) has been shown to be an effective alternative for the management of the overactive bladder (OAB). Transcutaneous Tibial Nerve Stimulation (TTNS) uses a series of regular electrical pulses to stimulate the tibial nerve. Numerous studies have positively shown the efficacy of this treatment. These studies have included multicentric, double-blind, randomized sham-controlled study of patients with idiopathic OAB. , . In 2013 the British National Institute for Health and Care Excellence (NICE) guidance has added TTNS as a second-line option for the management of female urinary incontinence , . In reality, the vast majority of patients treated using tibial nerve receive treatment percutaneously (PTNS) by inserting a needle into their lower leg. PTNS requires 12 visits to a physician's office and a painful treatment experience. From a physician's perspective PTNS is resource intensive in terms of time, financial and staff commitments. As a result, PTNS is often not a feasible option from the point of view of health care delivery. Moreover, the treatment may not be an option for patients whose schedule or ability to travel is limited. These issues are exacerbated for those with disabilities requiring special transport arrangements and who have trouble committing to 12 expensive and long trips to receive treatment. Additionally, 8% of patients who undergo PTNS complain of adverse effects which include pain, bruising, tingling or bleeding at the insertion site of the 34-gauge needle. As a direct result of these limitations long-term follow up studies of patients undergoing PTNS treatment show poor compliance to PTNS over time . Non-invasive, homecare TTNS devices such as the ZIDA Wearable Neuromodulation System are on the cusp of achieving regulatory clearance. TTNS, stimulates transcutaneously at a home-based setting and at least one study has explored the efficacy of this treatment method . Early results have demonstrated improvements in OAB symptom scores and urodynamic parameters . So far, these studies have employed standard commercial TENS devices (transcutaneous electrical nerve stimulation). These studies have used a variety of treatment frequencies to stimulate the tibial nerve at frequencies between 10 to 40 Hz, patient have been advised which pre-determined stimulation settings can be used for home care treatment. Commercial TENS devices limit mobility of patients during the time that the nerve is being stimulated.

Detailed description

The ZIDA device uses a series of regular electrical pulses to stimulate the tibial nerve for the management of overactive bladder by a patient in the home setting. The most common potential risk and complication associated with the ZIDA device are discomfort and pain (including throbbing pain) at, or near the stimulation site, including the patient's lower leg and foot; Redness/inflammation at, or near, the stimulation site; Numbness of toes. This study is designed to exclude those subjects who may be at risk for known and unknown complications. No other complications have been reported and there are no new or other expected complications or risks expected in this clinical study, making the safety profile of the ZIDA no greater than that of other tibial nerve stimulator products that are commercially used for treatment of overactive bladder. As mentioned above, the ZIDA device has a low potential for risks and complications. Therefore, the study Sponsor and Principle Investigator have determined that through their participation in this clinical study, the study subjects will be exposed to no new risks compared to the risks of devices currently available for similar intended uses. Specifically, the proposed study of ZIDA meets the definition of an NSR (nonsignificant risk) study for the following reasons: * ZIDA is NOT intended as an implant * ZIDA is NOT purported or represented to be for use supporting or sustaining human life * ZIDA does NOT present a potential for serious risk to the health, safety or welfare of a subject * ZIDA has a very low safety risk profile. * The study will be conducted by investigational centre and investigators with experience and expertise and sufficient staff to provide quality care to subjects requiring treatment of an overactive bladder. * The study was designed to mitigate any potential unknown risk through the eligibility criteria, subject selection and training on the ZIDA device. As addressed above, the ZIDA device does NOT otherwise present a potential for serious risk to the health, safety or welfare of a subject and meets the definition of a NSR study.
