The Liposorber Trial for Pediatric Patients with FSGS This study will determine if patients with FSGS can reach partial or full remission as a result of treatment with the LA-15 system. Liposorber LA-15 System is a blood processing system used outside of the body. This device removes certain lipoproteins (LDL/BDL) from the patient’s blood. The Liposorber LA-15 System is used in patients diagnosed with focal segmental glomerulosclerosis (FSGS.) either before transplant, or after a kidney transplant in which there is a recurrence of FSGS. The study is ongoing at pediatric sites. Treatment with this system is conducted at a medical clinic, and each treatment takes approximately 2-3 hours. The system is indicated for up to 12 uses in 9 weeks of treatment (twice weekly for three weeks, then once weekly for six weeks).
