1. Written informed consent obtained from the patient and ability for the patient to comply with the requirements of the study., 2. Male or female patients = 18 years old, 3. Patients diagnosed with ET according to the World Health Organization (WHO) 2016 criteria (with a bone marrow biopsy test result not more than 5 years old) who need cytoreductive treatment but are intolerant or refractory to, and/or ineligible for all cytoreductive treatments approved for the treatment of ET (i.e., HU, ANA, BUS, and PB). Patients resistant/intolerant to HU must have documented resistance/intolerance as defined by modified ELN criteria, whereby at least one of the following criteria is met: a) Platelet count >600 x 10^9/L at =2 g/day (or =2.5 g/day if patient body weight >80 kg) or maximally tolerated dose if <2 g/day or at maximum dose per local practice after at least 3 months of HU b) Platelet count >400 x 10^9/L and WBC count <2.5 x 10^9/L at any dose and any duration of HU c) Platelet count >400 x 10^9/L and haemoglobin (Hb) <10 g/dL at any dose and any duration of HU d) Presence of HU-related toxicities at any dose and any duration of therapy (e.g., leg ulcers, mucocutaneous manifestations, pneumonitis, or HU-related fever) Patients resistant/intolerant to ANA, BUS, or PB must meet at least one of the following criteria: a) Patient designated as non-responder according to the primary efficacy endpoint of this protocol (modified ELN criteria) after at least 3 months of treatment with the recommended dosing defined in SmPC or local practice b) Presence of treatment-related toxicities at any dose and any duration of therapy Patients ineligible for HU: with contraindication as defined by locally available HU SmPC or designated as such by investigator due to benefit-risk concerns (e.g., patients with toxic ranges of myelosuppression, teratogenic/leukaemogenic/carcinogenic concerns, male patients of reproductive age not willing or unable to use an effective method of contraception). Patients ineligible for ANA: with contraindication as defined by locally available ANA SmPC or designated as such by investigator due to benefit-risk concerns (e.g., cardiovascular risk factors, including heart failure, QT prolongation, the risk for progression to myelofibrosis). Patient ineligible for BUS and PB (in countries where BUS or PB is available and approved for treatment of ET): with contraindication as defined by locally available BUS/PB SmPC or designated as such by investigator due to benefit-risk concerns (e.g., teratogenic/leukaemogenic/carcinogenic concerns, male patients of reproductive age not willing or unable to use an effective method of contraception)., 4. If a patient received prior cytoreductive treatment for ET, the washout period between the last dose of treatment and the first dose of the study drug must be at least 14 days, or longer. (If the washout period not completed at time of first patients screening, washout may be done after obtaining ICF during the 28-day screening phase)., 5. Interferon treatment-naïve, 6. Adequate hepatic function defined as bilirubin =1.5 x upper limit normal (ULN), international normalised ratio =1.5 x ULN, albumin >3.5 g/dL, alanine aminotransferase =2.0 x ULN, aspartate aminotransferase =2.0 x ULN at screening., 7. Hospital Anxiety and Depression Scale (HADS) score 0-7 on both subscales., 8. Patient with HADS score of 8-10 inclusive on either, or both, of the subscales may be eligible following psychiatric as
1. Any patient requiring a legally authorised representative, 4. Existence of, or history of severe psychiatric disorders, particularly severe depression, suicidal ideation or suicide attempt, 5. Severe cardiovascular disease (i.e., uncontrolled hypertension, congestive heart failure (= NYHA class 2), serious cardiac arrhythmia, significant coronary artery stenosis, unstable angina) or recent stroke or myocardial infarction or pulmonary hypertension, 7. History or presence of autoimmune disease (excluding well-controlled Hashimoto’s disease), 8. Immunosuppressed transplant recipients, 9. Concomitant treatment with telbivudine, 10. Decompensated cirrhosis of the liver (Child-Pugh B or C), 6. Patients with diabetes mellitus that cannot be effectively controlled by medicinal products, 11. End stage renal disease (GFR <15 mL/min), 12. Symptomatic splenomegaly (per the investigator’s judgement), 13. Patients with any other significant medical conditions that, in the opinion of the Investigator, would compromise the results of the study or may impair compliance with the requirements of the protocol, including but not limited to: a) History of any malignancy within 5 years (except Stage 0 chronic lymphocytic leukaemia, basal cell, squamous cell, and superficial melanoma) b) Infections with systemic manifestations (e.g., bacterial, fungal, or human immunodeficiency virus [HIV], except hepatitis B [HBV] and/or hepatitis C [HCV], at screening) c) Evidence of severe retinopathy (e.g., cytomegalovirus retinitis, macular degeneration) or clinically relevant ophthalmological disorder (due to diabetes mellitus or hypertension) d) History of alcohol or drug abuse within the last year, 14. Use of any investigational drug <4 weeks prior to the first dose of study drug, or ongoing effects/symptoms due to prior administration of any investigational agent, 15. HADS score of 11 or higher on either, or both, of the subscales, and /or development or worsening of the clinically significant depression or suicidal thoughts, 16. Pregnant patients or breastfeeding patients or females of childbearing potential not willing to comply with contraceptive requirements as described in Section 16.1.4., 2. Any hypersensitivity to IFN-a or to any of the drug excipients, 3. Pre-existing thyroid disease, if not in remission or not controlled with conventional treatment
