- Platelet count > 1500 x 109/L
- Poor tolerance of phlebotomy or frequent phlebotomy requirement
- Symptomatic or progressive splenomegaly
- Severe disease-related symptoms (according to the investigators definition)
- Progressive leukocytosis with leukocyte count > 20 x 109/L For patients with high risk ET, AT LEAST ONE of the following must be fulfilled (according to DGHO guidelines):
- Age > 60 years
- Platelet count> 1500 x 109/L
- Previous thrombosis or thromboembolism
- Previous severe hemorrhage related to ET (defined as decrease of Hgb of at least 2 g/dl)
Patients must fulfill the following criteria regarding prior therapy:
PV patients:
Never treated with cytoreductive drugs except short-term therapy (up to 6 weeks maximum) with ONE of the following drugs: hydroxyurea, anagrelide, or interferon (phlebotomy and/or aspirin are allowed)
ET patients:
Naïve and pretreated patients may be entered in this trial.
- Patient must have adequate liver function as indicated by a total bilirubin, AST, and ALT ≤ 2 the institutional ULN value, unless directly attributable to the patient's MPN
- Patient must have a creatinine clearance >40ml/min calculated according to the modified formula of Cockcroft and Gault, eGFR, or directly measured after 24h-urine collection
- Able to swallow and retain oral medication
Exclusion Criteria:
- Patients who meet criteria for post PV-MF or post ET-MF (IWG-MRT)
- Patients who have received previous ruxolitinib treatment
- Patients who have a history of anaphylaxis following exposure to the BAT drug of choice
- Patients who have an inadequate bone marrow reserve as demonstrated by ANC ≤ 1 x 109/l OR platelet count <50 x 109/l
- Patients who have known hepatitis B or C or HIV infection
- Patients who suffer from other severe, concurrent diseases, including tuberculosis, serious cardiac functional dysfunction (class III or IV as defined by the New York Heart Association Classification), uncontrolled diabetes, uncontrolled hypertension, severe pulmonary disease (i.e. COPD with hypoxemia), or major organ malfunction that could interfere with the patient's ability to participate in the study
- Patients who have history of active substance or alcohol abuse within the last year
- Female patients who are pregnant or nursing
- Patients who have participated in another interventional trial and/or used investigational agents or concurrent anticancer treatment for concomitant disease within the last 4 weeks of registration
- Any circumstance at the time of study entry that would preclude completion of the study or the required follow-up prohibits inclusion into this study
- Subjects who have had an active malignancy during the previous 3 years except for treated cervical intraepithelial neoplasia, basal cell carcinoma of the skin, or squamous cell carcinoma of the skin, each with no evidence for recurrence in the past 3 years
- Patients who have uncontrolled bacterial, viral, or fungal infection
- Patients who have any medical condition requiring prolonged use of oral corticosteroids with a dose of more than 20 mg per day (> 1 month)
- Patients who have severe cerebral dysfunction and/or legal incapacity
- Patients who have had active splanchnic vein thrombosis within the last 3 months (includes Budd-Chiari, portal vein, splenic and mesenteric thrombosis)
- Patients who have thyroid dysfunction which is not adequately controlled
Fertile men or women of childbearing potential cannot be included unless they are:
- surgically sterile or > 2 years after the onset of menopause and/or
- willing to use a highly effective contraceptive method (Pearl Index <1) such as oral contraceptives, intrauterine device, sexual abstinence, or barrier method of contraception (i.e. condoms) in conjunction with spermicidal jelly during study treatment
Patients who are taking any of the following prohibited medication:
- clarithromycin, telithromycin, troleandomycin (antibiotics)
- ritonavir, indinavir, saquinavir, nelfinavir, amprenavir, lopinavir (HIV protease inhibitors)

Arm 2
Experimental
Active Comparator
Ruxolitinib
Best available therapy (BAT)
Ruxolitinib will be administered orally at a dose of 10 mg twice daily (both PV and ET) for two consecutive years.
BAT may include all currently used treatment options. BAT is at the choice of the investigator (monotherapy with i.e. hydroxyurea, anagrelide, interferon, busulfan, immunomodulators etc). BAT will be administrated for two consecutive years.
