Dr. McDevitt is the Course Director for Medical Students and Resident Rotations
Mixed Myelodysplastic/Myeloproliferative Neoplasms (Chronic myelomonocytic leukemia (CMML), atypical chronic myelogenous leukemia (aCML), MDS/MPN unclassifiable); primary and secondary myelofibrosis, myeloid disorders associated with monosomy 7 or 7q deletions. Patients are seen both in the medicine hematology clinic as well as in a specialty mixed MDS/MPN clinic jointly sponsored by the Sidney Kimmel Comprehensive Cancer Center. Dr. McDevitt also evaluates patients with anemia, thrombocytopenia, and neutropenia.
Dr. McDevitt's research focuses on unraveling the acquired genetic and epigenetic changes that lead to poor prognosis myeloid disorders. The long term goals include:
- Identify underlying pathways of deregulation to ultimately allow effective therapeutic targeting.
- Develop more sensitive and accurate biomarkers that improve diagnostic classification and prognostication and can be used in translational clinical trials.
- Apply these findings in early phase clinical trials for patients with accelerating myeloproliferative disorders and mixed myelodysplastic syndrome/myeloproliferative disorders. Of particular current interest are DNA repair pathways and Parp inhibitors.
Key collaborators include Judith Karp, Keith Pratz, James Herman, Alison Moliterno, Doug Smith, Hetty Carraway, Steve Gore, Cliff Takemoto, Scott Kaufmann (Mayo Clinic), and Jaroslaw Maciejewski (Cleveland Clinic).
