An interventional study of LIPOSORBER® LA-15 System in Focal Segmental Glomerulosclerosis, sponsored by Kaneka Medical America LLC. Recruiting at 12 sites in United States. Open to participants aged Up to 21 Years. Per ClinicalTrials.gov, last updated 2026-08-28.

Liposorber® LA-15 System is a blood purification therapy that selectively removes malignant lipoproteins including low density lipoprotein from circulating blood flow and rapidly reduces the plasma cholesterol level. The system was originally developed for the treatment of patients with serious dyslipidemia such as familial hypercholesterolemia and then applied to improve the dyslipidemia, a common complication of nephrotic syndrome and found to bring about improvement not only with the dyslipidemic condition but the nephrotic condition (e.g, proteinuria and hypoproteinemia).
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.
105 studies on the registry are indexed under Glomerulosclerosis, Focal Segmental; 33 are open to participants now.
This study's planned enrollment of 35 is above the median of 30 across 73 interventional studies indexed under Glomerulosclerosis, Focal Segmental.

General Exclusion Criteria
Medical Exclusion Criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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.
Device: 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.
