Ruxolitinib, also known as Jakafi, was first approved by the FDA in 2011 for the treatment of myelofibrosis. It is marketed by Incyte Corporation and Novartis Pharmaceuticals Corporation. Ruxolitinib works by inhibiting the activity of JAK enzymes, which play a crucial role in the development of myelofibrosis.
