Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
Inclusion Criteria:Subjects must satisfy the following criteria to be randomized in the study: 1. Subject is ≥18 years of age at the time of signing the ICF. 2. Subject has a diagnosis of PMF according to the 2016 World Health Organization (WHO) criteria or diagnosis of post-ET or post-PV MF according to the IWG-MRT 2007 criteria , confirmed by the most recent local pathology report. 3. Subject is requiring RBC transfusions as defined as: a. Average RBC-transfusion frequency: 4 to 12 RBC units/12 weeks immediately up to randomization. There must be no interval > 6 weeks (42 days) without ≥ 1 RBC transfusion. b. RBC transfusions are scored in determining eligibility when given for treatment of:
- - Symptomatic (ie, fatigue or shortness of breath) anemia with a pretransfusion Hgb ≤ 9.5 g/dL or.
- - Asymptomatic anemia with a pretransfusion Hgb ≤ 7 g/dL c.
Exclusion Criteria:The presence of any of the following will exclude a subject from randomization: 1. Subject with anemia from cause other than MPN-associated MForJAK2 inhibitor therapy (eg, iron deficiency, vitamin B12 and/or folate deficiencies, autoimmune or hemolytic anemia, infection, or any type of known clinically significant bleeding or sequestration). 2. Subject use of hydroxyurea, immunomodulatory compounds such as pomalidomide, thalidomide, ESAs, androgenic steroids or other drugs with potential effects on hematopoiesis ≤ 8 weeks immediately up to the date of randomization. 1. Systemic corticosteroids are permitted for nonhematological conditions providing the subject is receiving a constant dose equivalent to ≤ 10 mg prednisone for the 4 weeks immediately up to randomization. 2. Iron chelation therapy (ICT) is permitted providing the subject is receiving a stable dose for the 8 weeks immediately up to randomization. 3. Subject with any of the following laboratory abnormalities at screening: 1. Neutrophils: < 1 x 10^9/L. 2. White blood count (WBC): > 100 x 10^9/L. 3. Platelets: the lowest allowable level as approved for the concomitant JAK2 inhibitor but not < 25 x 10^9/L or > 1000 x 10^9/L. 4. Peripheral blood myeloblasts:> 5% 5. Estimated glomerular filtration rate:< 30 mL/min/1.73 m2 (via the 4-variable modification of diet in renal disease [MDRD] formula) or nephrotic subjects (eg, urine albumin-to-creatinine ratio > 3500 mg/g) 6. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT):> 3.0 x upper limit of normal (ULN) 7. Direct bilirubin: ≥ 2 x ULN.
- - Higher levels are acceptable if these can be attributed to active red blood cell precursor destruction within the bone marrow (eg, ineffective erythropoiesis) 4.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
