Brief summary
This prospective multi-center, open-label, single-arm study intends to gather and evaluate safety data for the nocturnal use of the HemoCare™ Hemodialysis System.
Detailed description
The HemoCare™ Hemodialysis System has been evaluated in previous clinical trials and is designed to perform hemodialysis (HD) in a clinic setting, in a self-care setting, or in a home environment for conventional HD, short daily HD or extended-duration HD therapy during the daytime or at night dependent on the users' lifestyle or work schedule. This multi-center, open-label, single-arm cross-over study is designed specifically to gather and evaluate safety data for the use of the HemoCare™ Hemodialysis System (including labeling and training tools) during home nocturnal (during sleeping hours based on the patient schedule) use. Nocturnal HD therapy was chosen as a treatment in this study because of the clinical and humanistic benefits associated with it. In addition, its risk profile, especially when performed in a home setting, may be greater than either existing conventional or short daily HD therapies. In this regard, establishing an acceptable safety profile for home nocturnal HD therapy should be sufficient evidence to support conventional and short daily HD home therapies with HemoCare™ Hemodialysis System.
Interventions
The HemoCare™ Hemodialysis System is intended for hemodialysis treatment, including short daily and nocturnal hemodialysis, of renal failure patients. The HemoCare™ Hemodialysis System is intended for use in chronic dialysis facilities, self-care dialysis facilities, or the home setting. All treatments must be prescribed by a physician and administered by a trained operator. Treatments must be performed under the supervision or assistance of a medical professional or a care partner who has been trained and deemed competent in the use of the device by the prescribing physician.
