CDK4 and 6 inhibitors and endocrine therapy have significantly improved outcomes in ER+/HER2- advanced breast cancer, and recently, the first CDK4 and 6 inhibitor was approved in combination with endocrine therapy in the adjuvant setting for patients with HR+/HER2-, node-positive, early breast cancer at high risk of recurrence and a Ki-67 score of ≥20%. However, pretreated ER+/HER2- breast cancer remains a challenging area with limited treatment options. A number of novel ER-targeting therapies are being investigated in this setting and are showing great promise, including oral selective estrogen receptor degraders (SERDs), selective estrogen receptor modifiers (SERMs), SERD/SERM hybrids, selective estrogen receptor covalent antagonists (SERCAs), and proteolysis-targeting chimeras (PROTACs). This activity, based on a PeerView Live Seminars & Practicum educational web broadcast held in conjunction with the 2022 ASCO Annual Meeting, provides the multidisciplinary breast cancer care team with the latest research and evidence on current and emerging targeted and endocrine therapy options and the implications of these therapeutic advances for practice to ensure that more patients benefit and have improved outcomes. The patient perspective is highlighted as well, and advice for overcoming persistent disparities in breast cancer clinical care are shared. Upon completion of this activity, participants should be better able to: Describe the rationale, mechanisms of action, and latest efficacy and safety data of approved and emerging treatment options for patients with ER+/HER2- breast cancer, including CDK4 and 6 inhibitors, SERDs, and SERCAs, and their evolving role in clinical practice; Develop personalized treatment plans for patients with ER+/HER2- breast cancer that take into account recent approvals and safety and efficacy findings from emerging therapies in the context of clinical practice or clinical trials, particularly in areas of high unmet need; and Integrate a team-based, collaborative, and coordinated approach to care, educate patients about new and emerging treatment options for which they may be eligible, and engage patients in shared decision-making to ensure that their unique needs and preferences are taken into account when making treatment decisions.
