Thalidomide derivatives are a mainstay of treatment in multiple myeloma, a cancer of white blood cells called plasma cells. However, around one in ten individuals treated with thalidomide derivatives for multiple myeloma will develop a blood clot, which can be life-threatening. It is critical to determine how to continue to use thalidomide derivatives to kill myeloma cells, while working to understand why these drugs increase the likelihood of clotting. Thalidomide derivatives work by degrading proteins important to myeloma cell growth; Dr. Zon [The Mark Foundation for Cancer Research Physician-Scientist] hypothesizes that these drugs could similarly lead to the degradation of proteins that prevent blood clotting. She is comprehensively evaluating what factors promote blood clots patients with multiple myeloma, with the goal of developing more targeted medications to prevent blood clots and improve treatment outcomes in blood cancer patients.
