Mayo Clinic Cancer Center researchers and collaborators from the M.D. Anderson Cancer Center have found “marked and durable” patient benefits from an experimental drug that inhibits a mutation responsible for myelofibrosis, a serious bone marrow disease that can lead to leukemia. The findings appear in the current New England Journal of Medicine. Researchers conducted a phase 1-2 clinical study with 153 patients over 14 months, testing effects of a kinase inhibitor called INCB018424 produced by Incyte pharmaceuticals, which also funded the study.
Results showed patients with debilitating symptoms — weight loss, fatigue and skin discomfort — experienced rapid improvement. Patients also showed lower levels of inflammation-producing cells. Over half of the patients receiving 15 mg. doses twice daily also showed reduction of enlarged spleens and sustained that benefit for 12 or more months.
