Director, Upstream Process Development

Jan 11, 2021

Sutro Biopharma, located in South San Francisco, has a unique capability that enables new molecular entities to be designed using a hybrid of synthetic and recombinant technologies to create best-in-class therapeutics in the oncology and auto-immune disease space. Our portfolio includes antibody-drug conjugates, bispecific antibodies, cytokine derivatives and other novel immuno-stimulatory approaches. These therapeutics will significantly extend the clinical impact of current oncology/autoimmune therapeutic approaches and are beyond what can be envisioned with traditional cell-based expression technologies. Sutro’s biochemical synthesis technology, which underpins these therapeutics, allows the rapid and systematic exploration of many protein drug variants to research, discover, and develop drug candidates. Our make-test cycle for hundreds of protein variants, including those incorporating non-natural amino acids, takes approximately two weeks. Once identified, production of these protein drug candidates can be rapidly and predictably manufactured at commercial scales. In addition to developing its own drug pipeline, Sutro Biopharma is collaborating with select pharmaceutical and biotech companies in the research, discovery, development, and manufacture of novel protein therapeutics.
