Safety in WM consistent with established BRUKINSA profile across B-cell malignancies1,2
The median follow-up time for Cohort 1 was 19.4 months.3
BRUKINSA had lower rates of:
Hypertension3
- Ibrutinib patients experienced nearly 2-fold higher incidence rate of hypertension on an exposure-adjusted basis (BRUKINSA vs ibrutinib: 0.7% vs 1.2%, respectively)
Major hemorrhage3
- Ibrutinib patients experienced nearly 2-fold higher incidence rate of major hemorrhage on an exposure-adjusted basis (BRUKINSA vs ibrutinib: 0.3% vs 0.6%, respectively)

BRUKINSA HAD LOWER RATES OF:

- Ibrutinib patients experienced nearly 10-fold higher incidence of atrial fibrillation/flutter on an exposure-adjusted basis (BRUKINSA vs ibrutinib: 0.1% vs 1.0%, respectively)
- No incidences of Grade ≥3 atrial fibrillation or flutter in patients who received BRUKINSA
