Trial Outcomes & Findings for Neulasta-controlled Trial of F-627 in Women With Breast Cancer Receiving Myelotoxic Chemotherapy (NCT NCT03252431)

NCT ID: NCT03252431

Last Updated: 2023-07-03

Results Overview

Eligible subjects were randomized in a 1:1 ratio. Subjects were dosed with either the F 627 20 mg/dose PFS or Neulasta® 6 mg/dose as the study drug in each chemotherapy cycle. Subjects remained in their assigned treatment arm throughout the study. Subjects were dosed subcutaneously (SC) 24 to 28 hours after receiving TC chemotherapy (75 mg/m2 docetaxel + 600 mg/m2 cyclophosphamide) on Day 2 of each chemotherapy cycle that the subject underwent (up to 4 cycles). Grade 4 (severe) neutropenia was defined as ANC \<0.5 × 109/L within the first 12 days of chemotherapy.
