Is Belinostat safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Belinostat. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
No information is available on the use of belinostat during breastfeeding. Because belinostat is >92% bound to plasma proteins, amounts in milk are likely to be low. The manufacturer states that breastfeeding is not recommended during treatment with belinostat, and for 2 weeks after the last dose.

“No published information” means the studies do not exist yet — not that Belinostat is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
