CDK4/6 inhibitors “have really been a game changer” in metastatic breast cancer, according to Komal Jhaveri, MD, clinical director for early drug development and section head for endocrine therapy research at Memorial Sloan Kettering in New York City. However, optimal treatment strategies have been complicated by a lack of head-to-head trials. Dr. Jhaveri speaks with Robert A. Figlin, MD, the Steven Spielberg Family Chair in Hematology-Oncology at Cedars-Sinai Cancer Center in Los Angeles, about how “practice patterns have slightly shifted” despite challenges in assessing efficacy across regimens and approaches. Dr. Jhaveri also discusses her work on the INAVO120 study, which found a benefit in adding a PI3K inhibitor to the combination of CDK4/6 inhibitors and hormone therapy. The trial reported a “monstrously important clinical hazard ratio,” according to Dr. Figlin, and may help clarify best practices moving forward.
