Company Profile

Sutro Biopharma, Inc., is a clinical-stage company developing next-generation cancer therapeutics, principally antibody-drug conjugates (ADCs), designed for greater potency, tolerability and improved safety. Sutro’s cell-free technology, XpressCF®, enables the design and manufacture of homogeneous product candidates with precise and empirically-demonstrated positioning of linker-payloads and consistent drug antibody ratio (DAR). Sutro’s platform has produced six clinical stage candidates to date, including two wholly-owned ADCs—luveltamab tazevibulin, or luvelta, a folate receptor alpha (FolRα)-targeting ADC in clinical studies for ovarian and endometrial cancers, as well as STRO-001, a CD74-targeting ADC in clinical studies for B-cell malignancies. In addition, the Company has a robust pipeline of preclinical and discovery stage candidates including STRO-003, a ROR1-targeting ADC, and STRO-004, a tissue factor-targeting ADC. Sutro has also entered into high-value collaborations with industry partners, including Astellas and Merck (MSD outside of the United States and Canada); and Sutro’s platform technology enabled the formation of Vaxcyte. Sutro is headquartered in South San Francisco. For more information, follow Sutro on Twitter, @Sutrobio, or visit
