Histone Deacetylase Inhibitor

Dosing in kidney impairment

Recommended Dosage in Patients with Renal Impairment Beleodaq dosage in patients with moderate renal impairment (creatinine clearance [CLcr] 30 to <60 mL/min) is 500 mg/m 2 administered over 30 minutes by intravenous infusion once daily on Days 1 through 5 of a 21-day cycle. Avoid use of Beleodaq in patients with severe renal impairment (CLcr < 30 mL/min).

No dosage adjustment is recommended for patients with mild renal impairment (CLcr 60 to < 90 mL/min).

Dosing in liver impairment

Recommended Dosage in Patients with Hepatic Impairment Beleodaq dosage in patients with moderate hepatic impairment (total bilirubin > 1.5 to 3 x ULN, any aspartate aminotransferase (AST)) is 500 mg/m 2 administered over 30 minutes by intravenous infusion once daily on Days 1 through 5 of a 21-day cycle. Avoid use of Beleodaq in patients with severe hepatic impairment (total bilirubin > 3 x ULN, any AST).

No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ 1.5 x ULN, any AST). Hepatic impairment is defined per the National Cancer Institute Organ Dysfunction Working Group.

Basis

Enter a dose to see draw volume, final concentration, and rates.

Preparation and Administration Beleodaq is a hazardous drug. Follow applicable special handling and disposal procedures. 1 Preparation: Aseptically reconstitute each vial of Beleodaq by adding 9 mL of Sterile Water for Injection into the Beleodaq vial with a suitable syringe to achieve a concentration of 50 mg of belinostat per mL.

Swirl the contents of the vial until there are no visible particles in the resulting solution. If not used immediately, the reconstituted product may be stored for up to 12 hours at room temperature (15°C to 25°C; 59°F to 77°F). Aseptically withdraw the volume needed for the required dosage (based on the 50 mg/mL concentration and the patient’s BSA [m 2 ]) and transfer to an infusion bag containing 250 mL of 0.9 % Sodium Chloride Injection.

If not used immediately, the infusion bag with drug solution may be stored at room temperature (15°C to 25°C; 59°F to 77°F) for up to 36 hours including infusion time. Visually inspect the solution for particulate matter. Do not use if cloudiness or particulates are observed. Administration: Connect the infusion bag containing drug solution to an infusion set with a 0.22 micron in-line filter for administration.

Infuse intravenously over 30 minutes. If infusion site pain or other symptoms potentially attributable to the infusion occur, the infusion time may be extended to 45 minutes.

Label text (3 paragraphs)

7 DRUG INTERACTIONS UGT1A1 Inhibitors: Avoid use or modify dosage if use is unavoidable. ( 2.6 , 7.1 )

7.1 UGT1A1 Inhibitors Avoid concomitant administration of Beleodaq with UGT1A1inhibitors. If concomitant use of a UGT1A1 inhibitor is unavoidable, modify the Beleodaq dose [see Dosage and Administration ( 2.6 )] . Belinostat is primarily metabolized by UGT1A1. Concomitant use with a UGT1A1 inhibitor increases belinostat exposure [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of Beleodaq adverse reactions.

Pregnancy and lactation

Pregnancy

8.1 Pregnancy Risk Summary Based on its mechanism of action, Beleodaq can cause teratogenicity and/or embryo-fetal lethality because it is genotoxic and targets actively dividing cells [see Clinical Pharmacology ( 12.1 ) and Nonclinical Toxicology ( 13.1 )] . There are no available data on Beleodaq use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. No animal reproduction studies were conducted with Beleodaq. Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

For breastfeeding, also see LactMed (National Library of Medicine), which summarizes milk levels and infant effects.

These are not what a patient pays at the pharmacy counter. They are what pharmacies, health plans, and government buyers pay, before manufacturer rebates. A patient's cost depends on their insurance (copay, coinsurance, or deductible) or the pharmacy's cash price.
