Trial summary

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Read more about this study

About this study

Official title: Anticoagulation Treatment of Patients With Gastroesophageal Varices and JAK2 V617 Mutation

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. The aim of this study is to evaluate the efficacy of anticoagulation in patients with JAK2 mutation and gastroesophageal varices.

The record says: status not confirmed, as of the sponsor's last update on 27 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xiaoquan HUANG, Ph.D (18801733835, huang.xiaoquan@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes of portal vein thrombosis (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04527666, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
