In today’s episode, our discussion features Aditya Bardia, MD, MPH, FASCO. Dr Bardia is a professor in the Department of Medicine in the Division of Hematology/Oncology, the director of Translational Research Integration, and a member of Signal Transduction and Therapeutics at the UCLA Health Jonsson Comprehensive Cancer Center in Los Angeles, California.

In our exclusive interview, Dr Bardia discussed key findings from the phase 3 lidERA Breast Cancer study (NCT04961996) showing the invasive disease–free survival superiority of giredestrant (GDC-9545) over standard endocrine therapy in patients with estrogen receptor–positive, HER2-negative early breast cancer. Our discussion also covered the ongoing phase 3 INAVO123 trial (NCT06790693), which is investigating inavolisib (Itovebi) plus CDK4/6 inhibitors and letrozole in patients with endocrine-sensitive, PIK3CA-mutated breast cancer. Dr Bardia also emphasized the importance of testing for ESR1 and PIK3CA mutations in order to better personalize treatment.
