What is the Selected Safety Information for PREVYMIS® (letermovir)?
- PREVYMIS is contraindicated in patients receiving pimozide or ergot alkaloids.
- Increased pimozide concentrations may lead to QT prolongation and torsades de pointes.
- Increased ergot alkaloids concentrations may lead to ergotism.
- PREVYMIS is contraindicated with pitavastatin and simvastatin when co-administered with cyclosporine. Significantly increased pitavastatin or simvastatin concentrations may lead to myopathy or rhabdomyolysis.
- The concomitant use of PREVYMIS and certain drugs may result in potentially significant drug interactions, some of which may lead to adverse reactions (PREVYMIS or concomitant drugs) or reduced therapeutic effect of PREVYMIS or the concomitant drug.
- The rate of adverse events occurring in at least 10% of HSCT recipients treated with PREVYMIS and at a frequency at least 2% greater than placebo were nausea (27% vs 23%), diarrhea (26% vs 24%), vomiting (19% vs 14%), peripheral edema (14% vs 9%), cough (14% vs 10%), headache (14% vs 9%), fatigue (13% vs 11%), and abdominal pain (12% vs 9%).
- Hypersensitivity reaction, with associated moderate dyspnea, occurred in one HSCT recipient following the first infusion of IV PREVYMIS after switching from oral PREVYMIS, leading to treatment discontinuation.
- The most common adverse event occurring in at least 10% of kidney transplant recipients treated with PREVYMIS and at a frequency greater than valganciclovir was diarrhea (32% vs 29%).
- If PREVYMIS is co-administered with cyclosporine, the dosage of PREVYMIS should be decreased to 240 mg once daily.
- Co-administration of PREVYMIS may alter the plasma concentrations of other drugs and other drugs may alter the plasma concentrations of PREVYMIS. Consult the full Prescribing Information prior to and during treatment for potential drug interactions.
- Closely monitor serum creatinine levels in patients with CLcr less than 50 mL/min using PREVYMIS injection.
- PREVYMIS is not recommended for patients with severe (Child-Pugh Class C) hepatic impairment.
- The safety and efficacy of PREVYMIS in patients below 18 years of age have not been established.
- For patients with creatinine clearance (CLcr) greater than 10 mL/min (by Cockcroft-Gault equation), no dosage adjustment of PREVYMIS is required based on renal impairment. The safety of PREVYMIS in patients with end-stage renal disease (CLcr less than 10 mL/min), including patients on dialysis, is unknown.
