An Open-Label, Bayesian Adaptive Phase II Clinical Study in HR+/HER2- Advanced Breast Cancer After Progression on Standard Therapy
This is a prospective, open-label, Bayesian adaptive Phase 2 clinical trial evaluating the efficacy and safety of a novel triple-combination therapy (CDK4/6 inhibitors + Fulvestrant + L-Ornithine L-Aspartate) in patients with HR-positive/HER2-negative advanced breast cancer (ABC) who have progressed on prior standard therapy including CDK4/6 inhibitors and endocrine therapy.
