NCT ID: NCT05421104 Completed - Clinical trials for Polycythemia Vera (PV)

Ruxolitinib for Polycythemia Vera in Patients Resistant to or Intolerant of Hydroxyurea.

Start date: November 27, 2020
Phase:
Study type: Observational

This was an analytical and descriptive, non-interventional, retrospective cohort study of PV patients aged ≥ 18 years in the US using a secondary data source, Optum EHR database.

NCT ID: NCT04243122 Completed - Clinical trials for Primary Myelofibrosis

Assessing Feasibility of Thromboprophylaxis With Apixaban in JAK2-positive Myeloproliferative Neoplasm Patients

AIRPORT-MPN
Start date: February 17, 2021
Phase: Phase 2
Study type: Interventional

Myeloproliferative neoplasms (MPNs) are blood disorders that occur when the body makes too many white or red blood cells, or platelets. This overproduction of blood cells in the bone marrow can create problems for blood flow and lead to various symptoms. One of the major problems is the formation of blood clots. These may form in the veins of a patient's legs or arms where they cause leg or arm pain, swelling or difficulty walking. These clots may travel to the lung and then cause chest pain, shortness of breath and sometimes death. Blood clots can also lead to poor or no blood flow to one's heart, brain, or other organs, causing damages that cannot be easily or ever repaired, such as stroke or heart attack. Patients diagnosed with certain types of MPN are associated with a higher risk of developing blood clots and related complications. For this reason, MPN patients are usually treated with low-dose aspirin, a common drug used for blood clot prevention, on long-term basis to prevent the formation of blood clots and other complications. However, recent studies also show that the risk of blood clots remains elevated in MPN patients treated with aspirin, and there may not be improvement or reduction in fatal or other events that are associated with blood clots. In addition, since this medical condition is rare, so there's a lack of studies done with high quality results to help physicians decide the best treatment plan for these patients. The study drug, apixaban, is a new type of orally-taken blood thinner that has been shown to be effective and safe for prevention and treatment of blood clots in various patient populations. The investigators will evaluate whether apixaban is safer and/or better at preventing blood clots and other complications in MPN patients compared to aspirin.

NCT ID: NCT04182100 Completed - Clinical trials for Polycythemia Vera (PV)

This is a Phase 2 single arm study to investigate efficacy and safety of P1101 for adult Japanese patients with PV.

NCT ID: NCT01816256 Completed - Myelofibrosis (MF) Clinical Trials

Screening for Asymptomatic Portal Vein Thrombosis and Portal Hypertension in Patients With Philadelphia Negative Myeloproliferative Neoplasms

Start date: May 2013
Phase: N/A
Study type: Interventional

This study involves screening for portal vein thrombosis and portal hypertension in patients with Philadelphia negative myeloproliferative neoplasms (MPNs). These include polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis. Portal vein thrombosis and portal hypertension are serious complications that are often seen in myeloproliferative patients. These complications are usually diagnosed when patients become symptomatic, and are often already at an advanced stage. They can further progress to cause non-reversible damage to the liver, also called cirrhosis of the liver. As a result of this, patients often accumulate fluid in the abdomen which is ascites; and can develop swelling of veins in the lining of the esophagus known as varices. If untreated, varices have the risk of rupturing resulting in life-threatening bleeding. When diagnosed at an advanced stage, the treatment is usually supportive therapy and there are no treatments available at present which can reverse these conditions. This study is looking at screening for these two conditions using Doppler ultrasound and upper gastrointestinal endoscopy.
