Results from an updated, unplanned survival analysis of the Phase III, randomized (2:1), open-label, multicenter, multinational EMBRACE trial of HALAVEN versus TPC (control arm) in patients with mBC (N=762), conducted when 77% of events (deaths) had been observed.1,4
mBC=metastatic breast cancer; OS=overall survival; CI=confidence interval; TPC=Treatment of Physician's Choice; EMBRACE=Eisai Metastatic Breast Cancer Study Assessing Physician's Choice E7389 (Eribulin).
aConducted in the intent-to-treat (ITT) population.
Results of the updated analysis were consistent with the primary analysis, which was conducted when ~50% of events (deaths) had been observed. HALAVEN demonstrated a median OS of 13.1 months (95% CI: 11.8, 14.3) vs 10.6 months with the TPC arm (95% CI: 9.3, 12.5), hazard ratio (HR)=0.81 (95% CI: 0.66, 0.99) (P=0.041)1,4
Reduction in risk of death—patients in the HALAVEN arm had a 19% reduction in risk of death vs real-world treatment options (defined as TPC)1,4-6
