About this study

This study is a multicenter, single-arm, open-label Phase II exploratory clinical trial designed to evaluate whether prophylactic use of leucogen can reduce the incidence of Grade 3 or higher neutropenia in early-stage HR+/HER2- breast cancer patients receiving ribociclib combined with endocrine therapy. The study plans to enroll 97 patients using a Simon two-stage design, with the primary endpoint being the incidence of severe neutropenia within 4 treatment cycles (4 months) after initiation. Secondary endpoints include the incidence of all-grade neutropenia, febrile neutropenia, ribociclib treatment intensity, and safety. The study will systematically assess the preventive efficacy and safety of leucogen to provide a basis for subsequent Phase III randomized controlled trials.
