Omjjara contains the active ingredient called momelotinib. Momelotinib is a type of medication known as aprotein kinase inhibitor.

Omjjara is used to treat adult patients with an enlarged spleen or other symptoms related to myelofibrosis, a rare form of blood cancer, and moderate to severe anemia.

In myelofibrosis, the bone marrow is replaced by scar tissue and is classified as:

• primary myelofibrosis, which develops in people who have not previously had problems with their bone marrow, or;
• secondary myelofibrosis, which develops in people who have other blood cancers, which causes their body to produce too many red blood cells (secondary myelofibrosis to polycythemia vera) or platelets, which helps blood to clot (secondary myelofibrosis to essential thrombocytosis).

How Omjjara works

One of the characteristics of myelofibrosis is the enlargement of the spleen. Myelofibrosis is a bone marrow alteration, in which the bone marrow is replaced by scar tissue. The altered bone marrow cannot produce a sufficient amount of normal blood cells, and as a result, the spleen increases significantly in size. Omjjara blocks the action of certain proteins, called Janus Kinases (JAK1, JAK2) and the activin A receptor, type 1 (ACVR1) that prevent the overproduction of cytokines and reduce inflammation. In this way, Omjjara reduces the size of the enlarged spleen, improves anemia, and symptoms such as fever, night sweats, bone pain, and weight loss caused by myelofibrosis.

Do not take Omjjara

• if you are allergic to momelotinib or any of the other components of this medication (listed in section 6). If you are unsure if this applies to you,do not take Omjjarauntil you have consulted with your doctor
• if you are pregnant or breastfeeding.
