Sorafenib is an inhibitor of multi-kinases including tyrosine and serine/threonine kinases. We investigated the efficacy and safety of sorafenib for the treatment of patients with refractory pulmonary arterial hypertension (PAH). Sorafenib was started in 9 patients (7 with idiopathic PAH, 2 with pulmonary veno-occlusive disease) who had severe PAH and right heart failure, in spite of treatment with vasodilators specific for PAH. Sorafenib was started as an add-on therapy at a dose of 50 or 100 mg/day, and increased to 100–400 mg/day. New York Heart Association functional class improved in 8 patients and did not change in 1. Mean pulmonary arterial pressure improved in 6 patients (14–28% decrease) and did not apparently change in 2 (follow-up catheterization was not performed in 1 patient). The main adverse effects of sorafenib were skin reactions on the hands and feet, which appeared in 5 patients. They were tolerable in 4 patients, but discontinuation of sorafenib was needed in only 1 patient. In conclusion, sorafenib had favorable effects to improve symptoms and objective variables in patients with refractory PAH, with tolerable adverse events. Sorafenib is an alternative strategy for patients with refractory PAH.
