Recruiting PHASE2 Myelofibrosis

New treatment option for Myelofibrosis

Official title A Study of Elritercept Alone or Together With Ruxolitinib in Adults With Myelofibrosis

ClinicalTrials.gov ID: NCT05037760

What this study is testing

What is Elritercept?

Elritercept is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for myelofibrosis.

Also referred to as KER-050, TAK-226.

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: The main aim of this study is to learn how safe elritercept is and how well it is tolerated when taken alone and in combination with the JAK inhibitor, ruxolitinib. Other aims are to learn about the effects of elritercept on the signs and symptoms of MF when taken with or without ruxolitinib and to learn how elritercept affects the body, how the body processes elritercept, and the effects of elritercept on anemia when taken with or without ruxolitinib The study will also check on how safe elritercept is and how well it is tolerated.
