Primary Myelofibrosis study: Momelotinib vs Luspatercept

Official title Study of Momelotinib in Combination With Luspatercept in Participants With Transfusion Dependent Myelofibrosis

ClinicalTrials.gov ID: NCT06517875

What this study is testing

What is Momelotinib?

Momelotinib is an investigational oral medicine being studied as a potential treatment for primary myelofibrosis and related myelofibrosis conditions. Momelotinib is designed to inhibit Janus kinase (JAK) signaling pathways that are overactive in myelofibrosis.

Also referred to as Ojjaara; CYT387.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study is testing whether the combination of momelotinib and luspatercept works and is safe for people with transfusion‑dependent myelofibrosis.
Who it's for
You may be able to join if you have primary myelofibrosis or post‑PV/ET myelofibrosis and need regular blood transfusions, whether or not you have taken a JAK inhibitor before.
What's involved
You will take momelotinib, a daily pill, and luspatercept, a monthly injection. You will visit the clinic for safety checks and blood tests.
Time commitment
The study lasts several months and requires regular clinic visits.
