Cautions
Thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia may occur; monitor blood cell counts and modify dosage for hematologic toxicities (see Dosage Modifications)
Serious and fatal infections (eg, pneumonia and sepsis) reported; do not administer if patient has an active infection
May cause hepatic toxicity and liver function test abnormalities; monitor liver function tests before treatment and before each treatment cycle; omit or modify dosage for hepatic toxicities (see Dosage Modifications)
Tumor lysis syndrome reported; monitor patients with advanced stage disease and/or high tumor burden and take appropriate precautions
Nausea, vomiting, and diarrhea commonly occur and may require the use of antiemetic and antidiarrheal medications
Can cause fetal harm when administered to a pregnant woman; advise women of potential harm to the fetus and to avoid pregnancy
Pregnancy & Lactation
Pregnancy
Based on mechanism of action, drug can cause teratogenicity and/or embryo-fetal lethality because it is genotoxic and targets actively dividing cells
There are no available data on drug 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 conducted; advise pregnant women of potential risk to fetus
Pregnancy testing is recommended for females of reproductive potential prior to initiating therapy
Based on findings from animal studies, drug may impair male fertility; reversibility of effect on fertility is unknown
Contraception
- Females: Drug can cause embryo-fetal harm when administered to a pregnant woman; advise females of reproductive potential to use effective contraception during treatment with drug and for 6 months after last dose
- Males: Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment and for 3 months after last dose
Lactation
There are no data on presence of drug in human milk, effects on breastfed child, or on milk production; because of potential for serious adverse reactions in breastfed child, advise patients that breastfeeding is not recommended during treatment with and for 2 weeks after last dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Histone deacetylase (HDAC) inhibitor; HDACs catalyze the removal of acetyl groups from the lysine residues of histones and some nonhistone proteins
In vitro, belinostat caused the accumulation of acetylated histones and other proteins, inducing cell cycle arrest and/or apoptosis of some transformed cells; shows preferential cytotoxicity towards tumor cells compared with normal cells
Distribution
Protein bound: 92.9-95.8%
Limited tissue distribution
Metabolism
Primarily by UGT1A1 (80-90%); also CYP2A6, CYP2C9, CYP3A4
Elimination
Half-life: 1.1 hr
Plasma clearance: 124 mL/min
Excretion: 40% urine (as metabolites); <2% urine (unchanged)
Pharmacogenomics
UGT1A1 activity is reduced in individuals with genetic polymorphisms that lead to reduced enzyme activity (eg, UGT1A1*28 polymorphism) ~20% of the black population, 10% of the white population, and 2% of the Asian population are homozygous for the UGT1A1*28 allele
Because belinostat is primarily (80-90%) metabolized by UGT1A1, the clearance of belinostat could be decreased in patients with reduced UGT1A1 activity (eg, patients with UGT1A1*28 allele)
Reduce initial dose in patients known to be homozygous for the UGT1A1*28 allele (see Dosage Modifications)

BELINOSTAT - INJECTION
(be-LIN-oh-stat)
COMMON BRAND NAME(S): Beleodaq
USES: Belinostat is used to treat a certain type of cancer (peripheral T-cell lymphoma - PTCL). Belinostat works by slowing or stopping the growth of cancer cells.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start using belinostat and each time you get a refill. If you have any questions, ask your doctor or pharmacist.This medication is given by a health care professional in a clinic or hospital. It is injected into a vein as directed by your doctor, usually once a day on days 1 through 5 of a 21-day treatment cycle. The injection is given slowly, usually over 30 minutes. Tell your doctor or nurse right away if you notice redness, pain, or swelling during your injection. If you have side effects during the injection, your infusion may be given over a longer time, changed, or temporarily stopped.The dosage is based on your medical condition, body size, lab tests, and response to treatment.To get the most benefit from this medication, do not miss any doses. To help you remember, mark the days when you are scheduled to receive treatment on your calendar.
SIDE EFFECTS: See also How to Use section.Tell your doctor if you have nausea, vomiting, or diarrhea. Your doctor may prescribe medications to prevent or relieve these symptoms. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. Tiredness, headache, constipation, decreased appetite, or dizziness may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Tell your doctor right away if you have any serious side effects, including: easy bleeding/bruising, swelling hands/ankles/feet, symptoms of anemia (such as severe tiredness, pale skin, shortness of breath).This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills, cough).Belinostat may rarely cause serious (possibly fatal) liver disease. Get medical help right away if you have any symptoms of liver damage, including: nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine.Belinostat sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as: low back/side pain (flank pain), signs of kidney problems (such as painful urination, pink/bloody urine, change in the amount of urine), muscle spasms/weakness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.
