Medical uses:

FILSPARI is a dual antagonist for endothelin and angiotensin II receptors, prescribed to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk of rapid disease progression. This typically includes patients with a urine protein-to-creatinine ratio (UPCR) of ≥1.5 g/g. It’s important to note that this indication is granted under accelerated approval based on the reduction of proteinuria, and it has not yet been confirmed whether FILSPARI slows the decline in kidney function in IgAN patients. Continued approval may depend on the results of a confirmatory clinical trial.

Dosage and Administration:

• Before Starting: Discontinue any renin-angiotensin-aldosterone system (RAAS) inhibitors, endothelin receptor antagonists (ERAs), or aliskiren.
• Initial Dose: Start with 200 mg orally once daily.
• After 14 Days: Increase to the recommended dose of 400 mg once daily, as tolerated.
• Resuming Treatment: If treatment is interrupted, consider starting again with 200 mg once daily and increasing to 400 mg once daily after 14 days.
• Administration: Instruct patients to swallow the tablets whole with water before their morning or evening meal.

Warnings & Precautions:

Hepatotoxicity: If patients show symptoms of hepatotoxicity, they should stop taking FILSPARI. Treatment should be paused if aminotransferase levels are abnormal and only resumed once levels normalize and symptoms disappear.

Embryo-Fetal Toxicity: FILSPARI can cause harm to a fetus, so it is contraindicated during pregnancy. Patients of childbearing potential must undergo pregnancy tests and use effective contraception.

FILSPARI REMS: Due to the risks of hepatotoxicity and embryo-fetal toxicity, FILSPARI is available only through a restricted program. Prescribers must be certified, patients must enroll in the program, and ongoing monitoring is required.

Hypotension: Some patients may experience low blood pressure. Adjustments to other antihypertensive medications and volume status may be necessary, with possible dose reduction or interruption of FILSPARI.

Acute Kidney Injury: Kidney function should be monitored, especially in patients dependent on the renin-angiotensin system.

Hyperkalemia: Regular monitoring of serum potassium levels is important, particularly for high-risk patients.

Fluid Retention: Significant fluid retention should be evaluated, and adjustments to diuretics or FILSPARI dosage may be needed.
