Journal Article

AIM: This is a pooled subgroup analysis of Asian patients enrolled in two Phase III confirmatory studies comparing proposed biosimilar LA-EP2006 with reference pegfilgrastim in women receiving chemotherapy for breast cancer. PATIENTS & METHODS: Women were randomized to LA-EP2006 (n = 90) or reference (n = 84) pegfilgrastim (Neulasta®, Amgen, Inc., CA, USA) for ≤6 cycles of TAC chemotherapy. Primary end point was duration of severe neutropenia during Cycle 1 (number of consecutive days with absolute neutrophil count <0.5 × 109/l) with equivalence confirmed if 95% CIs were within a ±1-day margin. RESULTS: Mean duration of severe neutropenia (days) in Cycle 1 was 1.36 ± 0.98 (LA-EP2006) versus 1.35 ± 1.06 (reference) (difference 0.01 days; 95% CI: -0.30-0.32, indicating equivalence). CONCLUSION: LA-EP2006 showed similar clinical efficacy and safety compared with reference pegfilgrastim.
