What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this Phase 2 study is to evaluate the efficacy and safety of momelotinib (MMB) in combination with luspatercept (LUSPA) in participants with transfusion dependence (TD) primary myelofibrosis (PMF) or Post-polycythemia vera (PV)/ essential thrombocythemia (ET) myelofibrosis (MF) who are either janus kinase (JAK) inhibitor (JAKi) naïve or experienced.

Will I have to stop taking my current medications?

The trial requires that you stop any active anti-myelofibrosis therapy at least 1 week before starting the study. Steroids for myelofibrosis must be stopped 14 days before the study, and certain other medications like potent CYP3A4 inducers should be stopped 14 days prior. Please consult with the study team for guidance on other medications.

Are You a Good Fit for This Trial?

This trial is for adults over 18 with high to intermediate risk primary myelofibrosis or post-PV/ET myelofibrosis, as per specific criteria. Participants can be new to JAK inhibitor treatment or have had previous treatments but must require regular blood transfusions due to low hemoglobin levels.

Inclusion Criteria

I have been diagnosed with PMF or myelofibrosis following PV/ET, according to WHO or IWG-MRT standards.

I have taken JAK inhibitors for myelofibrosis, or stopped due to side effects or needing blood transfusions.

My condition is classified as high or intermediate risk by DIPSS standards.
