⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

8 USE IN SPECIFIC POPULATIONS Lactation: Advised not to breastfeed. ( 8.2 )
8.1Pregnancy 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.
8.2Lactation 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
8.3Females and Males of Reproductive Potential Beleodaq can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . 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 ( 13.1 )]. 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 ( 13.1 )].
8.4Pediatric Use The safety and effectiveness of Beleodaq in pediatric patients have not been established.
8.5Geriatric 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 (14)]. 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).
8.6Use in Patients with Hepatic Impairment No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ 1.5 x ULN, any AST).

🆘 Overdosage ▾
10 OVERDOSAGE No specific information is available on the treatment of overdosage of Beleodaq. There is no antidote for Beleodaq and it is not known if Beleodaq is dialyzable. If an overdose occurs, general supportive measures should be instituted as deemed necessary by the treating physician. The elimination half-life of belinostat is 1.1 hours [see Clinical Pharmacology ( 12.3) ] .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Beleodaq is a histone deacetylase (HDAC) inhibitor. HDACs catalyze the removal of acetyl groups from the lysine residues of histones and some non-histone proteins. In vitro , belinostat caused the accumulation of acetylated histones and other proteins, inducing cell cycle arrest and/or apoptosis of some transformed cells.
Belinostat shows preferential cytotoxicity towards tumor cells compared to normal cells. Belinostat inhibited the enzymatic activity of histone deacetylases at nanomolar concentrations (<250 nM).
12.2Pharmacodynamics Belinostat exposure-response relationships and the time course of pharmacodynamic response are not fully characterized. Cardiac Electrophysiology Multiple clinical trials have been conducted with Beleodaq, in many of which ECG data were collected and analyzed by a central laboratory. Analysis of clinical ECG and belinostat plasma concentration data demonstrated no meaningful effect of Beleodaq on cardiac repolarization.
None of the trials showed any clinically relevant changes caused by Beleodaq on heart rate, PR duration or QRS duration as measures of autonomic state, atrio-ventricular conduction or depolarization; there were no cases of Torsades de Pointes.
12.3Pharmacokinetics The pharmacokinetic characteristics of belinostat were analyzed from pooled data from phase 1/2 clinical studies that used doses of belinostat ranging from 150 to 1200 mg/m 2 (0.15 to 1.2 times the approved recommended dosage). Distribution The mean belinostat volume of distribution approaches total body water, indicating that belinostat has limited body tissue distribution. In vitro plasma studies have shown that between 92.9% and 95.8% of belinostat is bound to protein in an equilibrium dialysis assay, and was independent of belinostat plasma concentrations from 500 to 25,000 ng/mL.
Elimination Belinostat elimination half-life is 1.1 hours with a total mean plasma clearance of 1240 mL/min. The total clearance approximates average hepatic blood flow (1500 mL/min), suggesting high hepatic extraction (clearance being flow dependent). Metabolism Belinostat is primarily metabolized by hepatic UGT1A1.
Belinostat also undergoes hepatic metabolism by CYP2A6, CYP2C9, and CYP3A4 enzymes. Excretion Following a single dose of radiolabeled belinostat (100 μCi, 1500 mg) administered as a 30-minute intravenous infusion in patients with recurrent or progressive malignancy, fecal excretion accounted for a mean (± SD) of 9.7% (± 6.5%) of the administered radioactive belinostat dose over 168 hours. The mean (± SD) of the administered radioactive belinostat dose that was excreted in urine over 168 hours was 84.8% (± 9.8%), of which unchanged belinostat accounted for only 1.7%.
Specific Populations Hepatic Impairment Belinostat steady state clearance decreased and AUC increased as a function of the degree of liver dysfunction, but were unchanged for C max , half‐life and apparent volume of distribution. Mean belinostat clearance was reduced by 18% in mild (total bilirubin ≤ ULN and AST >ULN, or total bilirubin ˃1 to 1.5 x ULN), 24% in moderate (total bilirubin ˃ 1.5 to 3 times ULN and any value for AST) and 33% in severe hepatic impairment (total bilirubin ˃ 3 to 10 times ULN and any value for AST).
Increases in belinostat exposure were correlated with worsening liver function, but there was no obvious relationship between exposure and DLTs during the first cycle of therapy. Renal Impairment Belinostat C max increased by 1.7-fold, AUC 0-∞ by 1.3-fold and CL tot was unchanged in patients with mild renal impairment (CLcr 60 to <90 ml/min). Belinostat C max and AUC 0-∞ increased by 1.7-fold and CL tot decreased by 26% in patients with moderate renal impairment (CLcr 30 < 60 ml/min).
The effect of severe renal impairment (CLcr < 30 mL/min) on belinostat pharmacokinetics is unknown. Drug Interaction Studies Clinical Studies and Model-Informed Approaches UGT1A1 inhibitors : Belinostat t 1/2 inc…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Beleodaq is a histone deacetylase (HDAC) inhibitor. HDACs catalyze the removal of acetyl groups from the lysine residues of histones and some non-histone proteins. In vitro , belinostat caused the accumulation of acetylated histones and other proteins, inducing cell cycle arrest and/or apoptosis of some transformed cells.
Belinostat shows preferential cytotoxicity towards tumor cells compared to normal cells. Belinostat inhibited the enzymatic activity of histone deacetylases at nanomolar concentrations (<250 nM).
