Job Description
Company Overview TwoStep Therapeutics is a biotechnology company developing a pipeline built around a unique tumor-targeting polyspecific integrin-binding peptide (PIP) that can selectively bind several targets that are highly expressed on solid tumors. This multi-targeting feature enables the agent's broad applicability to a wide range of tumor types and patient populations, overcoming the limitations of single-antigen targeting approaches. The company has leveraged this technology to create a pipeline of targeted cancer therapies for cytotoxic drug delivery and radioligand therapy. TwoStep Therapeutics was co-founded by CEO, Caitlyn Miller, in collaboration with leading academic entrepreneurs at Stanford University, including Nobel Laureate Carolyn Bertozzi, Jennifer Cochran, and Ronald Levy.
