Treosulfan
Medication given to people before they have a bone marrow transplant
Treosulfan, sold under the brand name Trecondi, is a medication given to people before they have a bone marrow transplant from a donor known as allogeneic hematopoietic stem cell transplantation. It is used as a 'conditioning' treatment to clear the bone marrow and make room for the transplanted bone marrow cells, which can then produce healthy blood cells.[8][9] It is used together with another medicine called fludarabine in adults and children from one month of age with blood cancers as well as in adults with other severe disorders requiring a bone marrow transplant.[8]
It belongs to the family of drugs called alkylating agents.[8] In the body, treosulfan is converted into other compounds called epoxides which kill cells, especially cells that develop rapidly such as bone marrow cells, by attaching to their DNA while they are dividing.[8]
The most common side effects in adults and children are infections, nausea (feeling sick), stomatitis (inflammation of the lining of the mouth), vomiting, diarrhoea and abdominal pain (belly ache).[8] Tiredness, febrile neutropenia (low white blood cell counts with fever) and high blood levels of bilirubin (a breakdown product of red blood cells) are also seen in more than 1 in 10 adults, and rash also affects more than 1 in 10 children.[8]
