- •Subject is willing and able to adhere to the study visit schedule and other protocol requirements
- •A female of childbearing potential (FCBP) must: a. Have 2 negative pregnancy tests as verified by the Investigator during screening prior to starting study treatment. She must agree to ongoing pregnancy testing during the course of the study, and after end of study treatment. This applies even if the subject practices true abstinence from heterosexual contact. b. Either commit to true abstinence from heterosexual contact (which must be reviewed on a monthly basis and source documented) or agree to use and be able to comply with highly effective contraception without interruption, –14 days prior to starting investigational product, during the study treatment (including dose interruptions), and for 30 days after discontinuation of study treatment.
- •A male subject must: Practice true abstinence (which must be reviewed on a monthly basis) or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for at least 30 days following investigational product discontinuation, or longer if required for each compound and/or by local regulations, even if he has undergone a successful vasectomy.
- •Subject has an Eastern Cooperative Oncology Group (ECOG) Performance Score (PS) of 0, 1 or 2
- •Subject has diagnosis of primary myelofibrosis (PMF) according to the 2016 World Health Organization (WHO) criteria, or diagnosis of post-ET or post-PV myelofibrosis according to the IWG-MRT 2007 criteria, confirmed by the most recent local pathology report
- •Subject has a DIPSS Risk score of Intermediate-2 or High
- •Subject has a measurable splenomegaly during the screening period as demonstrated by spleen volume of ≥ 450 cm3 by MRI or CT-scan and by palpable spleen measuring ≥ 5 cm below the left costal margin
- •Subject has a measurable total symptoms score (≥ 1) as measured by the Myelofibrosis Symptom Assessment Form (MFSAF)
- •Subject has been previously exposed to ruxolitinib, and must meet at least one of the following criteria (a and/or b) Treatment with ruxolitinib for ≥ 3 months with inadequate efficacy response (refractory) defined as < 10% spleen volume reduction by MRI or < 30% decrease from baseline in spleen size by palpation or regrowth (relapse) to these parameters following an initial response. b. Treatment with ruxolitinib for ≥ 28 days complicated by any of the following (intolerant): Development of a red blood cell transfusion requirement (at least 2 units/month for 2 months) or Grade ≥ 3 AEs of thrombocytopenia, anemia, hematoma, and/or hemorrhage while on treatment with ruxolitinib
- •Subject must have treatment-related toxicities from prior therapy resolved to Grade 1 or pretreatment baseline before start of last therapy prior to randomization
- •Subject must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted
排除标准
- •Any of the following laboratory abnormalities: a. Platelets < 50 x 10^9/L b. Absolute neutrophil count (ANC) < 1.0 x 10^9/L c. White blood count (WBC) > 100 x 10^9/L d. Myeloblasts ≥ 5 % in peripheral blood e. Estimated glomerular filtration rate < 30 mL/min/1.73 m2 (as per the Modification of Diet in Renal Disease [MDRD] formula) f. Serum amylase or lipase > 1.5 x upper limit of normal (ULN) g. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 3 x upper limit of normal (ULN) h. Total bilirubin > 1.5 x ULN, subject's total bilirubin between 1.5 – 3.0 x ULN are eligible if the direct bilirubin fraction is < 25% of the total bilirubin
- •Subject has received ruxolitinib within 14 days prior to randomization
- •Subject with previous exposure to Janus kinase (JAK) inhibitor(s) other than ruxolitinib treatment
- •Subject on treatment with aspirin with doses > 150 mg daily

- •Subject with diagnosis of chronic liver disease (eg, chronic alcoholic liver disease, autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, hemochromatosis, non-alcoholic steatohepatitis)
- •Subject with prior malignancy other than the disease under study unless the subject has not required treatment for the malignancy for at least 3 years prior to randomization. However, subject with the following history/concurrent conditions provided successfully treated may enroll: non-invasive skin cancer, in situ cervical cancer, carcinoma in situ of the breast, incidental histologic finding of prostate cancer (T1a or T1b using the tumor, nodes, metastasis [TNM] clinical staging system), or is free of disease and on hormonal treatment only
