Escalating Dose Study in Subjects With Relapsed or Refractory B Cell Non-Hodgkin Lymphoma, Chronic Lymphocytic Leukemia, and Waldenstrom's Macroglobulinemia

Bruton's tyrosine kinase (Btk) is non-receptor tyrosine kinase with restricted cellular
expression largely limited to B-lymphocytes, monocytes, and mast cells or basophils. Btk is
a critical component of the B cell receptor (BCR) signaling network and is crucial for B
cell development. Investigation has revealed that some B cell lymphomas and CLL depend on
BCR signaling, suggesting that interruption of such signaling could be a promising
therapeutic opportunity in B-NHL, CLL and WM.

Inclusion Criteria:
