Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the effect of Eflapegrastim on duration of neutropenia in patients with early-stage breast cancer when administered at varying intervals following Docetaxel and Cyclophosphamide administration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1, randomized, open label, actively-controlled study to evaluate the same day dosing of Eflapegrastim on duration of neutropenia when administered at varying intervals following Docetaxel and Cyclophosphamide (TC) chemotherapy in patients with early-stage breast cancer.

The study will be conducted in two phases: Early Phase and Expansion Phase.

1. In the Early Phase, approximately 45 patients were enrolled and randomized in a 1:1:1 ratio to 3 dosing time schedule arms. Each cycle was of 21 days. Total 4 cycles were evaluated for this phase. On Day 1 of Cycle 1, patients received Docetaxel and Cyclophosphamide (TC) chemotherapy followed by administration of Eflapegrastim at 1 of 3-time schedules post-TC (30 minutes \[mins\], 3 hours or 5 hours). During Cycles 2-4, patients received Eflapegrastim 24 hours after TC administration (on Day 2).
2. In the Expansion Phase, additional 45 patients will be enrolled in Cycles 1-4, who will receive fixed dose of Eflapegrastim 30 mins after TC administration (on Day 1).

Safety evaluations will be conducted once the first 3 patients (for Early Phase) and the first 6 patients (for Expansion Phase) have completed Cycle 1 to determine if it is safe for patients to continue in that particular treatment arm.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

Considering two-phase study, where Expansion Phase followed Early Phase. The dosing within the Early Phase was in parallel assignment wherein participants were assigned to three arms in a 1:1:1 ratio. Patients completing Early Phase will enter the Expansion Phase to receive dosing in a single arm.
