Chronic Myelomonocytic Leukemia (CMML)

Chronic myelomonocytic leukemia (CMML) has features of both myelomonocytic disorders and myeloproliferative disorders (MDS/MPN) which complicates its diagnosis and treatment. Thanks to our extensive knowledge in CMML therapy development, Protheragen is uniquely equipped to offer customized solutions and strategic support in your transition from CMML therapy research towards commercialization.

Introduction to Chronic Myelomonocytic Leukemia (CMML)

Chronic myelomonocytic leukemia (CMML) is a rare complex blood malignancy classified as myelodysplastic syndromes/myeloproliferative neoplasms (MDS/MPN). It is marked by the excessive generation of defective monocytes (a class of white blood cells) within the bone marrow. As a result, monocytes overflow into the blood and extramedullary tissues. This makes normal blood cell production difficult, and the patient may experience fatigue, infections, anemia, and an enlarged spleen.

Disease Subtypes Features Incidence
CMML-1 Blasts account for less than 5% in the blood and less than 10% in the bone marrow. 60–70%
CMML-2 Blasts account for 5–19% in the blood or 10–19% in the bone marrow. 30–40%

Pathogenesis of Chronic Myelomonocytic Leukemia (CMML)

The origin of chronic myelomonocytic leukemia (CMML) has its roots in an amalgamation of genetic mutations, signal dysregulation on the pathway, in addition to epigenetic abnormalities. Mutations within the critical TET2, ASXL1, SRSF2, and RAS genes are known to produce cells which don't fully differentiate and promote the monocytic cellular clonality expansion. Other significant alterations like excessive methylation of DNA sequences modify gene expression while overactivation of signaling pathways such as JAK-STAT and RAS-MAPK are capable of uncontrolled hyperproliferative cellular activity.

Therapy Development for Chronic Myelomonocytic Leukemia (CMML)

At present, therapeutic options for chronic myelomonocytic leukemia (CMML) are scarce, leaving a significant number of unmet medical needs. The diverse genetic mutations and presentations associated with CMML, alongside the resistance of many affected individuals to current therapies, present numerous challenges to effectively treating this condition. Consequently, there is a pressing demand for the development of novel therapies to better address the management of CMML.
