Company Overview

Xilio Therapeutics is a clinical‐stage biotechnology company focused on the discovery and development of tumor‐targeted cytokine therapeutics for the treatment of cancer. The company leverages a proprietary platform to design pro‐drug versions of potent immune‐modulating cytokines, enabling local activation of immune responses within the tumor microenvironment while limiting systemic exposure and toxicity.

The company’s lead programs utilize engineered interleukin‐12 (IL‐12) and interleukin‐2 (IL‐2) molecules fused to tumor‐binding antibodies or peptide ligands. These candidates are designed to selectively accumulate in tumor tissues and activate local innate and adaptive immunity. Xilio has advanced multiple assets into early‐phase clinical studies, evaluating safety, pharmacokinetics and preliminary signals of anti‐tumor activity across various solid tumor types. The pipeline also includes additional preclinical programs that apply the same targeting and activation principles to other cytokine payloads.

Founded in 2018 and headquartered in Cambridge, Massachusetts, Xilio Therapeutics has assembled a management team with deep experience in oncology drug development and biologics engineering. The company conducts its clinical trials primarily in the United States and Europe and collaborates with academic and industry partners to accelerate the translation of its pipeline candidates into potential cancer therapies. Xilio remains committed to advancing its modular cytokine platform to address unmet needs in immuno‐oncology.
