Warnings for Beleodaq
Included as part of the PRECAUTIONS section.
Precautions for Beleodaq
Hematologic Toxicity
Beleodaq can cause thrombocytopenia, leukopenia (neutropenia and lymphopenia), and/or anemia; monitor blood counts weekly during treatment, and modify dosage as necessary [see DOSAGE AND ADMINISTRATION and ADVERSE REACTIONS].
Infections
Serious and sometimes fatal infections, including pneumonia and sepsis, have occurred with Beleodaq. Do not administer Beleodaq to patients with an active infection. Patients with a history of extensive or intensive chemotherapy may be at higher risk of life threatening infections [see ADVERSE REACTIONS].
Hepatotoxicity
Beleodaq can cause fatal hepatotoxicity and liver function test abnormalities [see ADVERSE REACTIONS]. Monitor liver function tests before treatment and before the start of each cycle. Interrupt or adjust dosage until recovery, or permanently discontinue Beleodaq based on the severity of the hepatic toxicity [see DOSAGE AND ADMINISTRATION and CLINICAL PHARMACOLOGY].
Tumor Lysis Syndrome
Tumor lysis syndrome has occurred in Beleodaq-treated patients in the clinical trial of patients with relapsed or refractory PTCL [see Clinical Studies]. Monitor patients with advanced stage disease and/or high tumor burden and take appropriate precautions [see ADVERSE REACTIONS].
Gastrointestinal Toxicity
Nausea, vomiting and diarrhea occur with Beleodaq [see ADVERSE REACTIONS] and may require the use of antiemetic and antidiarrheal medications.
Embryo-Fetal Toxicity
Based on its mechanism of action and findings of genotoxicity, Beleodaq can cause fetal harm when administered to a pregnant woman [see CLINICAL PHARMACOLOGY and Nonclinical Toxicology]. Advise pregnant women of the risk to a fetus. Advise females of reproductive potential to use an effective method of contraception during treatment with Beleodaq and for 6 months after the last dose [see Use In Specific Populations]. Advise males with female partners of reproductive potential to use effective contraception during treatment with Beleodaq and for 3 months after the last dose.
Patient Counseling Information
Physicians should discuss the FDA approved PATIENT INFORMATION Leaflet with patients prior to treatment with Beleodaq. Instruct patients to read the Patient Information Leaflet carefully.
Advise the patient or the caregiver to read the FDA-approved patient labeling (Patient Information).
Advise patients or their caregivers:
- To report symptoms of nausea, vomiting and diarrhea so that appropriate antiemetic and antidiarrheal medications can be administered [see WARNINGS AND PRECAUTIONS].
- To report any symptoms of thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia [see WARNINGS AND PRECAUTIONS].
- To immediately report symptoms of infection (e.g., pyrexia) [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS].
- Of the potential risk to the fetus and for women to avoid pregnancy and use effective contraception while receiving Beleodaq and for 6 months after the last dose [see WARNINGS AND PRECAUTIONS]. Advise males with female partners of reproductive potential to use effective contraception during treatment with Beleodaq and for 3 months after the last dose.
- To avoid breastfeeding while receiving Beleodaq and for 2 weeks after the last dose [see Use In Specific Populations].
- To understand the importance of monitoring liver function test abnormalities and to immediately report potential symptoms of liver injury [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenicity studies have not been performed with belinostat.
Belinostat was genotoxic in a bacterial reverse mutation test (AMES assay), an in vitro mouse lymphoma cell mutagenesis assay, and an in vivo rat micronucleus assay.
Beleodaq may impair male fertility. Fertility studies using belinostat were not conducted. However, belinostat effects on male reproductive organs observed during the 24-week repeat-dose dog toxicology study included reduced organ weights of the testes/epididymides that correlated with a delay in testicular maturation.
Use In Specific Populations
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 and Nonclinical Toxicology]. 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.
Lactation
Risk Summary
There are no data on the presence of belinostat in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise patients that breastfeeding is not recommended during treatment with Beleodaq, and for 2 weeks after the last dose.
Females And Males Of Reproductive Potential
Beleodaq can cause embryo-fetal harm when administered to a pregnant woman [see Use In Specific Populations].
Pregnancy Testing
Pregnancy testing is recommended for females of reproductive potential prior to initiating Beleodaq.
Contraception
Females
Advise females of reproductive potential to use effective contraception during treatment with Beleodaq and for 6 months after the last dose.
Males
Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with Beleodaq and for 3 months after the last dose [see Nonclinical Toxicology].
Infertility
Males
Based on findings from animal studies, Beleodaq may impair male fertility. The reversibility of the effect on fertility is unknown [see Nonclinical Toxicology].
Pediatric Use
The safety and effectiveness of Beleodaq in pediatric patients have not been established.
Geriatric Use
In the single-arm trial, 48% of patients (N = 62) were ≥ 65 years of age and 10% of patients (N=13) were ≥ 75 years of age [see Clinical Studies]. The median age of the trial population was 63 years. Patients ≥ 65 years of age had a higher response rate to Beleodaq treatment than patients < 65 years of age (36% versus 16%) while no meaningful differences in response rate were observed between patients ≥ 75 years of age and those < 75 years of age. No clinically meaningful differences in serious adverse reactions were observed in patients based on age (< 65 years compared with ≥ 65 years or < 75 years of age compared with ≥ 75 years of age).
Use In Patients With Hepatic Impairment
No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ 1.5 x ULN, any AST). Reduce the Beleodaq dosage in patients with moderate hepatic impairment (total bilirubin > 1.5 to 3 x ULN, any AST) [see DOSAGE AND ADMINISTRATION]. Avoid use of Beleodaq in patients with severe hepatic impairment (total bilirubin > 3 x ULN, any AST) [see CLINICAL PHARMACOLOGY].
Belinostat is metabolized in the liver, moderate hepatic impairment (total bilirubin > 1.5 to 3 x ULN, any AST) and severe hepatic impairment (total bilirubin > 3 x ULN, any AST) increases belinostat exposure [see CLINICAL PHARMACOLOGY], which may increase the risk of Beleodaq adverse reactions.
Use In Patients With Renal Impairment
No dosage adjustment is recommended for patients with mild renal impairment (CLcr 60 to < 90 mL/min). Reduce the Beleodaq dosage in in patients with moderate renal impairment (CLcr 30 to <60 mL/min) [see DOSAGE AND ADMINISTRATION]. Avoid use of Beleodaq in patients with severe renal impairment (CLcr < 30 mL/min).
Moderate renal impairment (CLcr 30 to <60 mL/min) increases belinostat exposure [see CLINICAL PHARMACOLOGY], which may increase the risk of Beleodaq adverse reactions. The effect of severe renal impairment (CLcr < 30 mL/min) on belinostat pharmacokinetics is unknown [see CLINICAL PHARMACOLOGY].
