Research

This past year I worked in the lab of Dr. Stephen Oh in the Department of Hematology studying myeloproliferative neoplasms (MPN). Previous characterization of MPN (particularly myelofibrosis) and secondary AML patients in our lab revealed hyperactive activation of the NF-kB pathway, thus we investigated the efficacy of pevonedistat, a NEDD8-activating enzyme inhibitor which suppresses NF-kB signaling, as a viable therapeutic agent in these settings. We showed that pevonedistat reduced cancer proliferation in cell lines and colony growth in MPN and secondary AML patient primary samples. In mass cytometry studies, pevonedistat also inhibited hyperproduction of inflammatory cytokines and abrogated NF-kB activity in CD34+ cells from primary samples. Furthermore, pevonedistat treatment reduced disease burden and improved survival across multiple MPN mouse models. Our studies demonstrate pevonedistat could be an effective therapeutic for MPN patients, leading to initiation of a Phase I clinical trial.
