  • Anagrelide was first disclosed in US 3932407 as a compound useful at blood platelet anti-aggregative and/or antihypertensive and/or bronchodilator agents in mammals, including humans. In 1997, anagrelide was approved in the United States as a therapeutic agent for thrombocytosis associated with myeloproliferative neoplasm; in 2004, it was approved in Europe for the treatment of high-risk essential thrombocythemia patients.
  • Essential thrombocythaemia which is the most often occurring myeloproliferative disorder is a clonal malignant disorder arising from stem cell. It is a myeloproliferative neoplasm (MPN), which is, characterized by a sustained platelet increase in the peripheral blood and anomalous megakaryocyte growth in bone marrow biopsy.
  • Treatment goals comprise prevention of thrombohemorrhagic events (THEs), progression to myelofibrosis (MF) or acute leukemia (AL), and the onset of secondary malignancies.
