The International Waldenstrom’s Macroglobulinemia Foundation (IWMF), the only international organization dedicated solely to Waldenstrom’s macroglobulinemia (WM), is a patient-founded and patient-driven nonprofit with a simple but compelling mission: Support and educate everyone affected by WM to improve patient outcomes while advancing the search for a cure.  

We support the worldwide WM community by providing education, information, and support services through our headquarter office in the US, as well as 22 international affiliates. And we advance the search for a cure by investing in cutting-edge research projects throughout the world. Since 1999, the IWMF has invested more than 30 million USD in WM research leading to better treatment options with fewer side effects and longer-lasting remissions, resulting in WM patients living longer with higher-quality lives.
