About this trial
The objective of this clinical trial is to evaluate the efficacy (how well the drug works), safety, pharmacokinetics (PK), and pharmacodynamics (PD) of the study drug, RVU120, in treating adult patients with intermediate or high-risk, primary or secondary myelofibrosis. RVU120 will be given as a single agent or in combination with ruxolitinib.
