JAK inhibitor can provide long-term disease control in PV

At 80 weeks, the most common adverse events in the ruxolitinib arm were headache (22%), diarrhea (20%), pruritus (20%), and fatigue (17%). Grade 3 or 4 anemia and thrombocytopenia occurred in 2% and 6% of patients, respectively. Five percent of patients discontinued treatment due to adverse events.

“There is currently a significant unmet need for patients with polycythemia vera who are unable to tolerate or control their disease on other treatments,” Dr Kiladjian said. “For these patients, [ruxolitinib] represents a valuable new option, as confirmed by results from the long-term, phase 3 study.”
