Key exclusion criteria
- Presence of the following cardiac conditions:

1. New York Heart Association Class 3 or 4 heart failure

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,
