Descrizione del progetto
Dialisi renale a domicilio
L’insufficienza renale viene trattata con la dialisi renale, un procedimento che filtra e purifica il sangue da prodotti di scarto e liquidi in eccesso. In modo convenzionale, tale procedimento si svolge in una struttura sanitaria per mezzo di una macchina per la dialisi. L’obiettivo principale del progetto CORDIAL, finanziato dall’UE, è quello di convalidare clinicamente un nuovo sistema di dialisi peritoneale portatile e utilizzabile a domicilio o nel posto di lavoro. Grazie al sistema, il dialisato circola e si rigenera costantemente nella cavità perineale ottenendo una migliore purificazione del sangue rispetto ai dispositivi convenzionali. Inoltre, non richiede concentrazioni elevate di glucosio che danneggiano la membrana peritoneale. CORDIAL verificherà questo nuovo sistema di dialisi peritoneale sui pazienti direttamente a domicilio e lo metterà a confronto con i dispositivi attualmente in commercio.
Obiettivo
Goal is the clinical validation of a new peritoneal dialysis (PD) system called CORDIAL. Instead of a stagnant filling as in traditional PD, CORDIAL continuously circulates and regenerates dialysate in the peritoneal cavity. Hereby, a significant improvement in blood purification (2-3x) can be achieved in comparison to traditional PD. For the regeneration, a sorbent unit is used to remove toxins from the peritoneal dialysate by adsorption. The sorbent system also facilitates slow release of glucose needed for osmotic removal of excess fluid (i.e. ultrafiltration). Very high glucose concentrations, as used in traditional PD and harmful to the peritoneal membrane, are no longer required, which helps to preserve the membrane function. CORDIAL is an easy to use, portable/wearable machine that allows renal patients to dialyze conveniently at home or at work, independently from a fixed water supply, up to 24 h/day. With the improved clearance and low glucose load, CORDIAL eliminates current drawbacks of PD (low efficacy, high glucose concentrations leading to damage to the peritoneal membrane), benefiting the overall health condition and quality of life (fitness, lower pill burden).
In order to demonstrate clinical efficacy and safety of the system an early feasibility first-in-human (FIH) trial and a crossover feasibility trial will be performed in PD patients. The FIH study will involve a group of 12 stable PD patients who will be treated for 6 days with the new PD system spread over two weeks (3 consecutive days per week), which will be compared with baseline measurements in the week prior and after CORDIAL treatment. Upon successful functionality and safety analysis of the FIH trial, the clinical validation is continued in a crossover study to test the hypotheses that the system (1) improves blood purification, (2) results in adequate ultrafiltration at low glucose concentrations and (3) does not show important safety/ biocompatibility problems. Hereto 30 stable PD patients will be randomized to receive at home either CORDIAL treatment in the first 2 months and traditional PD in the month 3 and 4 or vice versa.
