Myelofibrosis (MF) is a rare myeloproliferative neoplasm characterized by progressive bone marrow fibrosis and splenomegaly. Ruxolitinib is the standard-of-care first-line treatment option for MF. This review summarizes real-world effectiveness and safety of ruxolitinib in more than 4500 patients with MF from real-world settings, including expanded-access and phase 4 trials, as well as registry, postmarketing, and retrospective studies in the 10 years since regulatory approval.

Background And Objectives: The oral, potent, and highly selective activin receptor-like kinase 2 (ALK2) inhibitor zilurgisertib (INCB000928) is in development as a treatment for fibrodysplasia ossificans progressiva (FOP), and for anemia due to myelofibrosis, myelodysplastic syndromes, and multiple myeloma. Saliva is an attractive alternative to blood for drug monitoring and pharmacokinetic analysis, as it is non-invasive to retrieve. This is beneficial for patients, such as those with FOP, for whom blood draws can be challenging due to soft tissue damage susceptibility that can cause progressive heterotopic ossification, and for whom tourniquet time and blood draws must be minimized.

Purpose: Anemia is a cardinal feature of myelofibrosis often managed with red blood cell (RBC) transfusions, which may contribute to negative prognostic, quality-of-life, and healthcare-related economic impacts. The Janus kinase (JAK) 1/JAK2/activin A receptor type 1 inhibitor momelotinib was approved for the treatment of patients with myelofibrosis and anemia based on clinical trial evidence of anemia, spleen, and symptom benefits illustrated using binomial response/nonresponse endpoints. In the present post hoc, descriptive analyses, the impact of momelotinib on RBC transfusion burden over time was further characterized across JAK inhibitor-naive and -experienced patients.

Myelofibrosis (MF) is a rare hematologic malignancy that is characterized by dysregulation of the JAK-STAT pathway resulting in fibrosis of the bone marrow, splenomegaly, and abnormalities in peripheral blood counts including anemia, leukocytosis, and thrombocytopenia. This disease has 2 phenotypic extremes - myeloproliferative and cytopenic. Cytopenic myelofibrosis presents with pronounced cytopenia and a different landscape of genetic mutations which results in worse clinical outcomes and a poor prognosis.

Background: Secondary myelofibrosis (SMF) is characterized by the excessive deposition of fibrous tissue on top of the primary disease, often causing clinical manifestations to be overshadowed by the primary disease. Unfortunately, current staging systems do not incorporate myelofibrosis, leading to potential treatment delays for SMF.
Objectives: To evaluate the prognosis of patients with multiple myeloma (MM) complicated with myelofibrosis.
