FDA Approval for Zanubrutinib in Waldenstrom macroglobulinemia (WM)
According to BeiGene, the drug’s manufacturer, the U.S. FDA has approved zanubrutinib (Brukinsa) capsules to treat adult patients with Waldenstrom macroglobulinemia (WM), a rare non-Hodgkin lymphoma. The FDA’s approval of BRUKINSA in WM is primarily based on efficacy results from the multicenter, open-label Phase 3 ASPEN trial (NCT03053440) comparing BRUKINSA to ibrutinib in patients with WM. A total of 201 patients with an MYD88 mutation (MYD88MUT) were enrolled in the randomized Cohort 1.

Waldenstrom macroglobulinemia (WM) is an indolent (slow-growing) subtype of non-Hodgkin lymphoma that affects small lymphocytes (white blood cells). WM probably begins with one or more acquired changes (mutations) to the DNA of a single B lymphocyte. Cancer causes the overproduction of a monoclonal protein called “immunoglobulin M” (IgM), which can result in a thickening of the blood known as “hyperviscosity”. This monoclonal IgM protein may lead to many symptoms, including fatigue, unexplained weight loss, enlarged lymph nodes or spleen, weakness, and unexplained bleeding. At the time of diagnosis, WM most commonly involves the blood and bone marrow; however, WM can start almost anywhere and spread to nearly every part of the body, affecting the lymph nodes, liver, spleen, and stomach intestines or lungs. WM rarely involves the skin or thyroid gland.
- WM is rare, with an incidence rate of about 6 cases per million people per year in the United States. About 1,000 to 1,500 people are diagnosed with WM each year in the United States.
However, the current Waldenstrom macroglobulinemia (WM) treatment market share, market uptake, attribute analysis concerning the most potential emerging therapies (IMO-8400, APG2575, Perifosine, Zanubrutinib, Enzastaurin, etc.) has been provided under the market outlook section of the study covering 8 MM countries; The United States, EU5 (Germany, Spain, France, Italy, UK) Japan and China.
In terms of pharmacologic therapies, several pharmaceutical products are being approved and under different phases of development for Waldenstrom macroglobulinemia (WM) treatment. The key companies in the advanced development stage are Eli Lilly and Company, Acerta Pharma BV, BeiGene, Celgene Corporation, etc., targeting WM.
