The alfapump® system is not currently approved in the United States or Canada. In the United States and Canada, the alfapump® system is currently under clinical investigation (POSEIDON Study) and is being studied in adult patients with refractory or recurrent ascites due to cirrhosis. For more information regarding the POSEIDON clinical study see www.poseidonstudy.com.
The DSR® therapy is still in development and it should be noted that any statements regarding safety and efficacy arise from ongoing pre-clinical and clinical investigations which have yet to be completed.
The DSR® therapy is not currently approved for clinical research in the United States or Canada. There is no link between the DSR® therapy and ongoing investigations with the alfapump® system in Europe.
This is a a multi-centre, prospective, single-arm, first-in-human study to evaluate the safety and feasibility of alfapump DSR®. Up to 10 patients diagnosed with stable chronic heart failure on high dose oral diuretics will be implanted with the alfapump DSR® system ( alfapump® and implanted surgical port) across two centres in Belgium and Georgia.
The primary safety endpoints include absence of device, procedure and/or therapy related serious adverse events through day 14 and the rate of device, procedure and/or therapy related serious adverse event through day 42. Secondary feasibility endpoints include the ability of alfapump DSR® to maintain a neutral sodium balance in the absence of diuretic therapy and the sustained effect of DSR® to maintain euvolemia through week 6. Additional exploratory endpoints will evaluate the potential impact of DSR® to restore response to diuretics following DSR® therapy.
