LY-004 Efficacy

38-month MEDIAN follow-up

Secondary endpoints at 38-month median follow-up*1

Median PFS was 22 months (95% CI: 17-33)1

  • Estimated 36-month PFS was 37% (95% CI: 28-46)1

OS data are immature; median OS not yet reached1

  • Estimated 36-month OS rate was 61% (95% CI: 51-69)1
  • At a median follow-up of 38 months, 55/124 (44%) patients remain in follow-up for survival with 24/124 (19%) patients still receiving acalabrutinib treatment.1
  • At a median follow-up of 38 months, 81% (100/124) discontinued acalabrutinib due to reasons including disease progression (n=74), adverse events (n=14), initiation of subsequent anticancer therapy (n=6), death (n=1), lost to follow-up (n=1)1
  • There were 57 deaths (46%) at any time during the study, most commonly due to PD (n=38; 31%) or AEs (n=6; 5%)1
    • 6 deaths due to AEs included those due to bilateral pulmonary embolism, critical aortic stenosis, myelodysplastic syndrome, pneumonia, suicide, and non-small cell lung cancer1

*The 38-month median follow-up data have not been reviewed by the FDA and are not included in the Prescribing Information for CALQUENCE.

Time-to-event endpoints, such as PFS and OS, in a single-arm study, cannot show treatment benefit.

AEs=adverse events; CI=confidence interval; OS=overall survival; PD=progressive disease; PFS=progression-free survival.
