To assess the safety of the intrahepatic reinfusion of increasing numbers of autologous highly purified CD133+ stem cells (SCs) to patients with end-stage liver disease. Safety will be evaluated as the incidence of adverse event (graded according to WHO) and clinically significant abnormal laboratory value following reinfusion of SCs.
To assess the feasibility of the immunomagnetic selection of autologous CD133+ cells collected with leukapheresis from the peripheral blood (PB) of patients with end-stage liver disease, previously mobilized with G-CSF. To assess the effects of the intrahepatic reinfusion of highly purified CD133+ cells on residual hepatic function of the patients.
Twelve patients will be enrolled. At first, G-CSF at 7.5µg/Kg/b.i.d. will be administered subcutaneously (sc) from day 1 until the completion of peripheral blood stem cells (PBSC) collection. Harvest of bone marrow (BM)-derived PBSC will begin on day + 4 only if the concentration of CD133+ cells is > 8/uL and will be continued until the collection of the target cell dose: 0.5 x 106 CD133+ cells/Kg for the first 2 cohorts of patients; 1 x 106 CD133+ cells/Kg for cohort 3 and 2 x 106 CD133+ cells/Kg for cohort 4 (see below for definitions). PB mononuclear cells obtained from mobilized standard-volume leukapheresis will be incubated with Macs colloidal superparamagnetic CD133 microbeads and CliniMacs device will be used for the positive selection of CD133+ cells under good manufacturing practice (GMP) conditions. Cryopreservation and storage in liquid nitrogen will be performed according to standard procedures. At least 4 weeks after SC mobilization and collection, up to 40 mL of single cell suspension of highly purified autologous CD133+ cells, obtained after rapid thawing, will be infused through the hepatic artery by transfemoral or transbrachial arteriography. Infusion time will be lower than 15ml/min to avoid thrombi formation. The entire procedure will be performed under anesthesiological control. According to modified Fibonacci's increment rule, highly purified G-CSF-mobilized CD133+ cells will be administered to patients starting from 5x104/Kg patient's body weight and increased every 3 patients. The maximum infused cell dose will be 1x106/kg. G-CSF at 5µg/Kg/day will be administered sc for 3 days after the reinfusion of SCs (day 0 to day +2).
