In a Phase III clinical trial, treatment of intermediate-2 or high-risk myelofibrosis with Jakafi® (ruxolitinib) improved survival and reduced spleen size. These results were published in Blood.
Myelofibrosis is a type of blood cancer known as a myeloproliferative neoplasm. It involves the abnormal development and function of bone marrow cells that produce blood cells and leads to the formation of scar tissue in the bone marrow. This can cause anemia, enlargement of the spleen and liver, fatigue, and other problems. In some patients with myelofibrosis, the condition progresses to acute myeloid leukemia.
Jakafi—approved in 2011—is currently the only drug that has been approved specifically for myelofibrosis. It is a targeted therapy known as a JAK inhibitor. Jakafi can help to relieve the signs and symptoms of myelofibrosis, such as enlargement of the spleen, night sweats, itching, and bone or muscle pain.
The current report provides long-term follow-up of a Phase III clinical trial (the COMFORT-II trial). The study enrolled 219 patients with intermediate-2 or high-risk myelofibrosis. Patients were treated with either Jakafi or best standard therapy, and have now been followed for a median of three years.
These results provide additional evidence that Jakafi improves outcomes among patients with myelofibrosis.
