Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Although the definitive mechanism by which the system may relieve nephrotic syndrome is unknown, it has been recognized as one of alternative therapies for refractory nephrotic syndrome including focal segmental glomerulosclerosis (FSGS) in Japan and referred in the Guidelines for the Treatment of Nephrotic Syndrome endorsed by The Japanese Society of Nephrology.
This study is conducted as a post approval study imposed by Humanitarian Device Exemption (HDE) order to confirm the safety and efficacy of the Liposorber® LA-15 System in the treatment of drug-resistant pediatric primary FSGS.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Liposorber® LA-15 System
All study patients who meet the study eligibility criteria will undergo the extracorporeal treatment using Liposorber® LA-15 System. The participants are to be treated with the system twice weekly for the 3weeks and then once weekly for the following 6 weeks.
LIPOSORBER® LA-15 System
LIPOSORBER® LA-15 System is an extracorporeal blood purification system. Approximately 3 to 4 L of plasma is treated in a single treatment session and it takes 2 to 3 hours. Recommended frequency of the treatment is twice weekly for 3 weeks followed by once weekly for 6 weeks, thus it takes 9 weeks for a total of 12 treatment sessions.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Refractory nephrotic syndrome in which standard treatment options are unsuccessful (i.e., patient is unresponsive to standard corticosteroid and/or calcineurin inhibitor therapy for at least 8 weeks resulting in failure to achieve complete or partial remission);
* Refractory nephrotic syndrome in which standard treatment options are not well tolerated (i.e., patients intolerant to standard therapies due to severe side effects that negatively affect quality of life without providing an acceptable level of clinical benefit);
* Refractory or recurrent nephrotic syndrome in which standard therapy is contraindicated.
or
\- Pediatric post renal transplant patients with nephrotic syndrome associated with primary FSGS.
Exclusion Criteria
* Parent or patient is unwilling or unable to sign and date the informed consent (Note: Only patients 18-21 years of age may sign the informed consent on their own behalf)
* Pregnant, lactating, or planning to become pregnant prior to completing the study (Note: The safety of the use of Liposorber® in pregnant women has not been studied. There may be unknown risks to an embryo/fetus. Sexually active women of child bearing potential should avoid pregnancy during the use of the Liposorber device and throughout the study duration.)
* Unable or unwilling to comply with the follow-up schedule
* Simultaneously participating in another investigational drug or device study
* Body weight \< 15 kg (33.1 lbs)
* Currently being administered ACE inhibitors that cannot be withheld for at least 24 hours prior to each apheresis treatment (Note: The time period to withhold ACE inhibitors should be prolonged, if determined by the treating physician, considering each individual's renal function and the biological half-life of the ACE-inhibitor currently in use.)
* Currently being administered antihypertensive drugs other than ACE inhibitors (e.g., Angiotensin II receptor blockers (ARBs) that cannot be withheld on the day of apheresis until after the procedure
* Medical condition or disorder that would limit life expectancy to less than the primary clinical study endpoint or that may cause noncompliance with the study plan or confound the data analysis
* Hypersensitivity to dextran sulfate, heparin, or ethylene oxide
* Adequate anticoagulation cannot be achieved due to severe hemophilia, severe hemorrhage diathesis, severe gastrointestinal ulcers, or are recipients of vitamin K antagonist medications
* Extracorporeal circulation therapy with Liposorber® LA-15 System cannot be tolerated due to severe cardiac insufficiency, acute myocardial infarction, severe cardiac arrhythmia, acute apoplexy, severe uncontrollable hypertension, or severe uncontrollable hypotension
* Cardiac impairments such as uncontrolled arrhyth¬mia, unstable angina, decompensated congestive heart failure, or valvular disease
* Functional thyroid disease or liver abnormalities
* Unresolved systemic or local infection that could affect the clinical study outcomes
