Belinostat, sold under the brand name Beleodaq, is a medication used to treat peripheral T-cell lymphoma (PTCL).[1] It is used when other treatments have failed.[2] Regarding if it improves life expectancy is unclear as of 2020.[2] It is given by injection into a vein.[1]

Common side effects include nausea, tiredness, fever, and low red blood cells.[2] Other side effects may include low platelets, low white blood cells, infection, liver problems, and tumor lysis syndrome.[2] Use in pregnancy may harm the baby.[2] It is a histone deacetylase inhibitor.[1]

Belinostat was approved for medical use in the United States in 2014.[2] It was given an orphan designation in Europe in 2012.[4] In the United States a vial of 500 mg costs about 2,100 USD as of 2022.[5]

Medical uses


It is given at a dose of 1,000 mg/m2 once a day on days 1-5 out of a 21-day cycle.[2]

Mechanism of action

Belinostat is primarily metabolized by UGT1A1; the initial dose should be reduced if the recipient is known to be homozygous for the UGT1A1*28 allele.[6]: 179 and 181 


Belinostat has been granted orphan drug and fast track designation by the FDA,[7] and was approved in the US for the use against peripheral T-cell lymphoma on 3 July 2014.[8]

It is not approved in Europe as of August 2014.[9]


In 2007 preliminary results were released from the Phase II clinical trial of intravenous belinostat in combination with carboplatin and paclitaxel for relapsed ovarian cancer.[10] Final results in late 2009 of a phase II trial for T-cell lymphoma were encouraging.[11]
