Mark Christopher Markowski, MD, PhD, Johns Hopkins Medicine, Baltimore, MD, discusses the final analysis of the Phase Ib/II study of sabizabulin, a novel oral cytoskeleton disruptor, in men with metastatic castration-resistant prostate cancer (mCRPC) who progressed on an androgen receptor targeting agent. This clinical trial demonstrated that chronic oral daily dosing of sabizabulin has a favorable safety profile with significant preliminary cytotoxic and cytostatic antitumor activity. This interview took place at the American Society of Clinical Oncology (ASCO) 2022 Annual Meeting in Chicago, IL.
