IMPORTANT SAFETY INFORMATION
INDICATION
REZUROCK® (belumosudil) is indicated for the treatment of adult and pediatric patients 12 years and older with chronic graft-versus-host disease (chronic GVHD) after failure of at least two prior lines of systemic therapy.
IMPORTANT SAFETY INFORMATION
Warnings and Precautions
- Embryo-Fetal Toxicity: Based on findings in animals and its mechanism of action, REZUROCK can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment with REZUROCK and for one week after the last dose
Adverse Reactions
- The most common (≥ 20%) adverse reactions, including laboratory abnormalities, were infections, asthenia, nausea, diarrhea, dyspnea, cough, edema, hemorrhage, abdominal pain, musculoskeletal pain, headache, phosphate decreased, gamma glutamyl transferase increased, lymphocytes decreased, and hypertension
- Permanent discontinuation of REZUROCK due to adverse reactions occurred in 18% of patients. The adverse reactions which resulted in permanent discontinuation of REZUROCK in > 3% of patients included nausea (4%). Adverse reactions leading to dose interruption occurred in 29% of patients. The adverse reactions leading to dose interruption in ≥ 2% were infections (11%), diarrhea (4%), and asthenia, dyspnea, hemorrhage, hypotension, liver function test abnormal, nausea, pyrexia, edema, and renal failure with (2% each)
- Monitor total bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) at least monthly
Drug Interactions
- Strong CYP3A Inducers: Coadministration of REZUROCK with strong CYP3A inducers decreases belumosudil exposure, which may reduce the efficacy of REZUROCK. Increase the dosage of REZUROCK to 200 mg twice daily when coadministered with strong CYP3A inducers
- Proton Pump Inhibitors: Coadministration of REZUROCK with proton pump inhibitors decreases belumosudil exposure, which may reduce the efficacy of REZUROCK. Increase the dosage of REZUROCK to 200 mg twice daily when coadministered with proton pump inhibitors
- Certain UGT1A1 substrates: Avoid coadministration of REZUROCK with UGT1A1 substrates, for which minimal concentration changes may lead to serious toxicities. If coadministration cannot be avoided, decrease the UGT1A1 substrates dosage(s) in accordance with the respective Prescribing Information. REZUROCK is an inhibitor of UGT1A1. Coadministration of REZUROCK with a UGT1A1 substrate decreased plasma concentrations of the glucuronide metabolite, which may increase the risk of adverse reactions related to sensitive substrates of UGT1A1
- Certain P-gp, OATP1B1, and BCRP substrates: Avoid coadministration of REZUROCK with P-gp, OATP1B1, and BCRP substrates, for which minimal concentration changes may lead to serious toxicities. If coadministration cannot be avoided, decrease the P-gp, OATP1B1, and BCRP substrates dosage(s) in accordance with the respective Prescribing Information. REZUROCK is an inhibitor of P-gp, OATP1B1, and BCRP. Coadministration of REZUROCK with P-gp, OATP1B1, and BCRP substrates increased their plasma concentrations, which may increase the risk of adverse reactions related to these substrates
Use in Specific Populations
- Pregnancy: There are no available human data on REZUROCK use in pregnant women to evaluate for a drug-associated risk. Advise pregnant women and females of reproductive potential of the potential risk to the fetus
- Lactation: There are no data available on the presence of belumosudil or its metabolites in human milk or the effects on the breastfed child, or milk production. Because of the potential for serious adverse reactions from belumosudil in the breastfed child, advise lactating women not to breastfeed during treatment with REZUROCK and for one week after the last dose
- Pediatric Use: The safety and effectiveness of REZUROCK in pediatric patients less than 12 years old have not been established
- Geriatric Use: Of the 186 patients with chronic GVHD in clinical studies of REZUROCK, 26% were 65 years and older. No clinically meaningful differences in safety or effectiveness of REZUROCK were observed in comparison to younger patients
- Renal Impairment: Treatment with REZUROCK has not been studied in patients with pre-existing severe renal impairment. For patients with pre-existing severe renal impairment, consider the risks and potential benefits before initiating treatment with REZUROCK
- Hepatic Impairment: Avoid use in patients with moderate hepatic impairment (Child-Pugh B) or severe hepatic impairment (Child-Pugh C) without liver GVHD. No dose adjustment is recommended for patients with mild hepatic impairment (Child-Pugh A)
