"According to the evaluation of the Independent Review Committee (IRC) and the principal investigators,the treatment of R/R WM patients with orelabrutinib at a dose of 150mg once a day reached the primary end point,showing encouraging efficacy,which is expected to improve with the extension of treatment time," said Professor Daobin Zhou,Director of Hematology Department of Peking Union Medical College Hospital. "Meanwhile,orelabrutinib is well tolerated with safety profile in the treatment of WM patients. The incidence of adverse events,especially off-target related serious adverse events,is significantly lower in the clinical trial."

About Waldenström's Macroglobulinemia

Waldenström's macroglobulinemia is a relatively slow-growing lymphoma characterized by the invasion of bone marrow by lymphoplasmacytic cells secreting monoclonal immunoglobulin M (IgM). The disease usually affects older adults and is primarily found in the bone marrow,although it may also impact lymph nodes and the spleen.
