Genetic mutations by themselves are rarely enough to flip the switch. Inflammation also plays a role. But, until now, the question of "how" remained unanswered.
Apexian Chief Science Officer Mark Kelley, PhD, and his colleagues presented their findings at the American Society of Hematology (ASH) (Free ASH Whitepaper)’s December 1, 2018 meeting in San Diego, California. When a putative tumor-suppressor gene called TET2 does not function well, acute inflammation or infection can enhance the production of myeloid stem and progenitor cells in the bone marrow that are precursors to circulating mature myeloid cells. The TET2 loss of function amplifies; inflammatory proteins increase, and myeloid cells rapidly mature, increasing in sheer numbers as well as developing resistance to programmed cell death.
Myeloid cells, which contribute to immunity, are normally very short-lived. However, when those cells live too long or become too numerous, dangerous levels of inflammation can result. Using a mouse model, Kelley and his colleagues demonstrated that Apexian’s flagship compound APX3330 can prevent precancerous cells from proliferating and block cells from making inflammatory proteins.
Such anti-inflammatory therapy could be of clinical value in people carrying TET2 mutations.
"Apexian continues to develop a robust portfolio of APE1/Ref-1 compounds that have broad utility in oncology, hematology and other diseases," says Steve Carchedi, President and CEO. "We are excited by the recent scientific findings and continue to expand our research and development beyond solid tumors."
APX3330 also has clinical utility with solid tumors. A Phase 1 trial for patients with advanced solid tumors is concluding
