Since the FDA’s approval of palbociclib plus letrozole in 2015, cyclin-dependent kinase 4/6 inhibitors (CDK4/6i), in combination with endocrine therapy (ET), have become the standard of care for treating hormone receptor-positive, human epidermal growth factor receptor 2-negative, locally advanced/metastatic breast cancer (HR+/HER2- LABC/mBC) in the first-line (1L) treatment setting. However, there is no clear standard of care for patients after 1L CDK4/6i treatment. Understanding the real-world effectiveness of subsequent therapies may help to identify an unmet need in this patient population.
The Value & Evidence team at EVERSANA (Sarah Kane, Belal Howidi, Ngoc Nguyen, Joanna Bielecki and Imtiaz A. Samjoo) synthesized the effectiveness of treatments received in the real-world setting after 1L CDK4/6i therapy in patients with HR+/HER2- LABC/mBC. This comprehensive systematic literature review aimed to shed light on the real-world effectiveness of treatments administered after 1L CDK4/6i.
The authors determined that treatment selection following 1L CDK4/6i therapy remains challenging, primarily due to the suboptimal effectiveness and/or significant toxicities associated with currently available options.
