About this trial
This study will test an experimental drug called ZE74-0282 in people with certain blood disorders caused by a specific mutation called JAK2 V617F. The main goals are to find the right dose level, to see how safe and tolerable different doses are, how the drug moves through the body, and whether it shows early signs of anti-tumor activity. Participants will receive ZE74-0282 in one of several dose groups. The study is open-label, meaning both the doctor and the participant know which treatment is given. It will take place at multiple centers across different countries. Blood tests and regular check-ups will be done to monitor side effects and measure the effect on the disease.
Eligibility criteria
Qualifiers

Patient has histological confirmation JAK2 V617F mutated hematologic diagnosis with later confirmation using ipsogen® JAK2 RGQ PCR Kit) with prior therapy or who have declined them.
Alopecia (Grade ≤2)
Disqualifiers
Clinical signs/symptoms of leukostasis or thrombophilia require urgent therapy (phereses).
Known active infection with Human Immunodeficiency Virus (HIV), hepatitis B or hepatitis C. Patients with a history of positive serology for hepatitis B or C require a negative Polymerase chain reaction (PCR) test for virus to go onto therapy.
Disseminated intravascular coagulopathy with active, unmanageable bleeding or signs of thrombosis.
Patients who have received an investigational agent (for any indication) <14 days prior the first dose of ZE74-0282; an investigational agent is one for which there is no approved indication by the United States (US) FDA or by the applicable regulatory authority in the country where the study is being conducted. Additionally, the first dose of ZE74-0282 should not occur before the shorter of 28 days or a period of 5 half-lives of the investigational drug; if the half-life of the agent is unknown, patients must wait 4 weeks prior to first dose of study treatment.
