2. QTcF >500 msec on the screening or C1D1 electrocardiogram (ECG)
3. Uncontrolled clinically significant arrhythmia (participants with rate-controlled atrial fibrillation are not excluded)
4. Acute myocardial infarction or unstable angina pectoris <6 months prior to C1D1
* History of stroke, deep venous thrombosis, or arterial embolism within 6 months prior to C1D1.
* Any malignancy other than PMF, post-ET MF, or post-PV MF that has not been in remission and/or has required systemic therapy including radiation, chemotherapy, hormonal therapy, or surgery, within 1 year prior to C1D1.
