Testing revealed that Bob has chronic lymphocytic leukemia, a form of blood cancer that is rare among horses but common among humans.

Bob’s veterinarians teamed up with Dr. John Byrd at the OSU Comprehensive Cancer Center to find a solution for his disease.

Byrd’s team led efforts to develop both first- and second-generation oral drugs to treat CLL and Bob is being treated with what they consider a breakthrough drug called Ibrutinib. This would be the first time the medicine has been used to treat a pony. 

“With these pills, particularly in older patients with this disease, they take the pill once a day and the disease goes away,” Byrd said.

Bob started therapy earlier this month and his care team says they can already see improvements in his blood work.
