HSE recommends BRUKINSA as an option for treating adult patients with WM who have received at least one prior therapy, or as first-line treatment for patients unsuitable for chemo-immunotherapy.1
ASPEN is the first and only head-to-head BTK inhibitor study in WM, with ~4 years median follow-up2–4

There were no CRs in either treatment arm2
While the primary endpoint of superiority did not reach
statistical significance (p=0.09), numerically higher VGPR rates
were achieved in the BRUKINSA treatment arm at a median
follow-up of 19.4 months2

Best overall response rates in patients with WM receiving BRUKINSA at extended follow-up5
Cohort 1: patients with MYD88 mutation, n=102;
Cohort 2: patients with MYD88 wild type, n=28; median follow-up 69.8 months

Less patient-reported diarrhoea, nausea and vomiting
