The LIPOSORBER® LA-15 System offers an advanced apheresis treatment for patients suffering from nephrotic syndrome associated with primary Focal Segmental Glomerulosclerosis (FSGS). It is a vital option for those who have not responded well to, or cannot tolerate, standard drug therapies. 

Indications For Use: Who is LIPOSORBER® For?

The LIPOSORBER® LA-15 System is indicated for use in the treatment of adult and pediatric patients with nephrotic syndrome associated with primary FSGS when:

  • Standard treatment options, including corticosteroids and/or calcineurin inhibitor treatments, are unsuccessful or not well tolerated, AND the patient’s Glomerular Filtration Rate (GFR) is  ≥ 60 ml/min/1.73 m2
  • OR the patient is post-renal transplantation.

How LIPOSORBER® Works: The Treatment Process

LIPOSORBER® employs a simple, automated process to target and remove harmful lipoproteins that may contribute to kidney disease.

  1. Blood is withdrawn from the patient and channeled through a plasma separator.
  2. The separated plasma passes through the LIPOSORBER Adsorption Column, which selectively removes Apo-B-containing lipoproteins such as LDL, Lp(a), and VLDL.
  3. The filtered plasma is recombined with the patient’s blood cells, warmed, and then returned to the patient.
  4. The computer-regulated machine automatically switches to a secondary column after processing 600ml of blood, allowing the primary column to regenerate and prepare for the next cycle of adsorption.

(Please note: the exact process may vary by patient and treating facility.)

Selectivity & Efficacy: Targeting the Root of Proteinuria

Targeted Selectivity Feature

The specialized adsorbent columns are made of dextran sulfate cellulose beads. This material provides highly specific binding to Apo-B containing lipoproteins (LDL-C, Lp(a), and VLDL).

These lipoproteins are selectively removed via an electrostatic interaction between the negatively charged dextran sulfate and the positively charged Apo-B moiety. Unlike therapeutic plasma exchange (TPE), LIPOSORBER® minimally affects other essential blood components, making it a highly targeted treatment.

The Mechanism of Benefit

By effectively decreasing harmful total cholesterol and LDL-C levels, LIPOSORBER® promotes several therapeutic benefits against FSGS and proteinuria:

  • Direct Podocyte Effects: Decreases lipotoxicity (fat-related damage) to the glomeruli (the kidney’s filtering units).
  • Immunologic Effects: Improves the cellular response to common medications like corticosteroids and cyclosporine.
  • Anti-inflammatory Effects: Removes pro-inflammatory factors, such as cytokines (e.g., IFN-gamma and IL-12), which can exacerbate kidney disease.

Potential Effectiveness: Reducing Proteinuria and Improving Renal Function

Studies suggest that treatment with LIPOSORBER® may offer significant improvements for patients with drug-resistant FSGS:

Improved Drug Response: Lipoprotein-apheresis (LA) therapy enhances corticosteroid and cyclosporine action in patients with drug resistance, likely by restoring cellular uptake and inhibiting drug efflux.

Reduced Urine Protein Levels: LIPOSORBER® therapy has induced complete or partial remission of proteinuria in up to 50% of patients with drug-resistant FSGS.

Improved Renal Function: Enabled nearly 50% of steroid-resistant primary FSGS patients to attain complete or partial remission over a two-year study duration.

Reduced Lipids in Blood: By reducing LDL-C, Lp(a), and TG, LIPOSORBER® therapy has the potential to preserve the graft and prevent the restarting of dialysis in transplant recipients.

Demonstrated Clinical Record and Approvals

LIPOSORBER® has a strong global clinical record:

  • It is well-tolerated by the majority of patients who receive the treatment.
  • Japan: Treatment for FSGS has been covered by both Public Health Insurance and Employees’ Health Insurance (EHI) since 1992.
  • U.S. FDA Humanitarian Use Device: Humanitarian Device Exemption (HDE) granted for use in the U.S. for nephrotic syndrome associated with primary FSGS (Note: IRB approval is required under HDE before treatment for Health Care Professionals).

Side Effects

ADVERSE EVENTS: The most common adverse events are hypotension (0.8%), nausea/vomiting (0.5%), and flushing/blotching (0.4%). Other adverse reactions include angina/chest pain, shortness of breath, fainting, lightheadedness and anemia.

CONTRAINDICATION: Angiotensin converting enzyme [ACEI(s)] inhibitors are contraindicated with LIPOSORBER® due to possible bradykinin reaction. ACEI(s) should be replaced with angiotensin II receptor blockers (ARBs) or any other antihypertensive agent as determined by the prescribing physician.
