The purpose of this study is to determine if investigational Ropeginterferon alfa-2b-njft (P1101) is safe and effective at treating participants with pre-fibrotic/early primary myelofibrosis.
Investigational means that Ropeginterferon alfa-2b-njft (P1101) is not approved by the U.S. Food and Drug Administration.
This is a randomized, double-blind, placebo-controlled study. “Randomized” means that the group you will be placed in is decided by chance, similar to drawing numbers out of a hat or flipping a coin. “Double-blind” means that neither you nor the study doctor will know which study group you have been placed in (i.e., if you are receiving P1101 or placebo).
In this study, Ropeginterferon alfa-2b-njft (P1101) will be administered subcutaneously (SC) every 2 weeks.
Participation is expected to last about 2.5 years
