X4 is also planning to commence clinical trials of mavorixafor in Severe Congenital Neutropenia (SCN) and 
Waldenstrom's macroglobulinemia (WM) in 2019.
This includes the use of ibrutinib in combination with obinutuzumab in adult patients with previously untreated chronic lymphocytic leukaemia and the use of ibrutinib plus rituximab for the treatment of adult patients with 
Waldenstrom's macroglobulinemia.
X4 Pharmaceuticals and The Leukemia & Lymphoma Society, or LLS, announced a collaboration to accelerate the development of X4's lead product candidate, mavorixafor for the treatment of 
Waldenstrom's macroglobulinemia, or WM, a rare form of non-Hodgkin lymphoma.

Disease prevention company The Janssen Pharmaceutical Companies of Johnson & Johnson Tuesday received the US Food and Drug Administration (FDA) approval for IMBRUVICA (ibrutinib) in combination with rituximab for the treatment of 
Waldenstrom's macroglobulinemia (WM), a rare blood cancer.
Ibrutinib was approved by the Federal Drug Agency for treatment of B cell malignancies including CLL, mantle cell lymphoma, multiple myeloma, diffuse large B cell lymphoma, and 
Waldenstrom's macroglobulinemia between 2013 and 2015.
Waldenstrom's macroglobulinemia (WM) is a lymphoplasmacytic lymphoma (LPL) that is characterized by high levels of monoclonal immunoglobulin M (IgM) protein in the blood.
 Differential diagnostic procedure should be carried out to exclude lymphoproliferative disease such as multiple myeloma and 
Waldenstrom's macroglobulinemia. (6) Both described patients underwent detailed check-up to exclude the hematologic disease.
The patient had an extensive and complex medical history that included non-Hodgkin's lymphoma, now in remission; an illness diagnosed by some as POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, circulating M protein, and skin changes) and by other physicians as 
Waldenstrom's macroglobulinemia; hepatic cirrhosis with a TIPS procedure (transjugular intrahepatic portosystemic shunt), a TIPS revision, and at least one episode of hepatic encephalopathy; systemic arterial hypertension; diabetes mellitus; and mild chronic renal insufficiency.
The company currently markets Imbruvica, a BTK-inhibitor approved to treat chronic lymphocytic leukemia, mantle cell lymphoma and 
Waldenstrom's macroglobulinemia, and VenclextaTM, a BCL-2 inhibitor approved to treat CLL in patients with 17p deletion.
During the quarter, the FDA approved IMBRUVICA for the treatment of 
Waldenstrom's Macroglobulinemia and for PREZCOBIX in combination with other antiretroviral medicinal products for the treatment of HIV-1.
