Viltepso (viltolarsen) Disease Interactions

There is 1 disease interaction with Viltepso (viltolarsen):


Antisense oligonucleotides (Includes Viltepso) renal impairment

Moderate Potential Hazard, Moderate plausibility. Applies to: Renal Dysfunction

Renal toxicity has been observed in animals receiving antisense oligonucleotides including golodirsen, casimersen, and viltolarsen. Renal toxicity has not been observed in clinical studies with these agents, but clinical experience is limited, and renal toxicity, including potentially fatal glomerulonephritis, has been observed after administration of some antisense oligonucleotides. Serum cystatin C, urine dipstick, and urine protein-to-creatinine ratio should be measured prior to therapy with urine dipstick repeated monthly and serum cystatin C and UPCR repeated every 3 months during therapy. The glomerular filtration rate may be measured using an exogenous filtration marker prior to therapy. For patients with Duchenne muscular dystrophy (DMD), creatinine may not be a reliable measure of kidney function due to a reduced skeletal muscle mass. If persistent increases in serum cystatin C or proteinuria are detected, the patient should be referred to a nephrologist for further evaluation. Patients with known renal function impairment should be closely monitored during treatment.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
