Extending the ELEVATE-TN to four additional years (beyond the two-year follow-up in the pivotal trial) showed ongoing efficacy with no new safety signals. Additionally, the four year ELEVATE-RR trial comparing acalabrutinib with ibrutinib as monotherapy in high-risk populations showed overall non-inferiority of acalabrutinib and a lower rate of several adverse events, including atrial fibrillation.
