  • The image above displays results from an active site competitive binding assay implicating kinase inhibition. A total of 395 non-mutant kinases were screened in the testing of CALQUENCE and ibrutinib (conducted in 2014). Compounds were tested at a single concentration of 1 μM3
  • Testing of zanubrutinib (conducted in 2017) included 8 additional non-mutant kinases (total of 403 screened); the 8 additional kinases were not inhibited by >65% by zanubrutinib3
  • In the TREEspotTM interaction maps developed by KINOMEscan®, some circles are overlapping and therefore counting may be difficult. The degree of inhibition vs untreated control is represented by circle size2,3
  • The clinical relevance of these preclinical data has not been determined. Mechanism of action statements are not meant to imply efficacy and safety
  • There are no head-to-head trials between CALQUENCE and zanubrutinib comparing safety or efficacy
