Lerociclib Plus Fulvestrant Shows Promise in HR+/HER2- Advanced Breast Cancer
• The LEONARDA-1 phase 3 trial demonstrated that lerociclib plus fulvestrant significantly improved progression-free survival (PFS) compared to placebo plus fulvestrant in patients with HR+/HER2- advanced breast cancer.
• The combination of lerociclib and fulvestrant showed a manageable safety profile, with hematological toxicities being the most common adverse events, effectively managed with dose adjustments.
• Lerociclib plus fulvestrant exhibited efficacy across various patient subgroups, including those with primary endocrine therapy resistance and liver metastasis, addressing a critical unmet need.
• The study supports lerociclib plus fulvestrant as a potential treatment option for patients with HR+/HER2- advanced breast cancer who have progressed on prior endocrine therapy.
