Pionyr Immunotherapeutics is a biotechnology research company headquartered in South San Francisco, California, with 51-200 employees. Founded in 2015, it operates as a clinical-stage organization that discovers and develops antibody therapeutics intended to modulate the tumor microenvironment and enhance the immune system's ability to fight cancer. Its Myeloid Tuning technology seeks to tilt the tumor microenvironment toward immune-activating cells while reducing immune-suppressing cells, with potential use in combination with checkpoint inhibitors, and it is pursuing a pipeline targeting transmembrane and intracellular antigens. The company has engaged in partnerships and strategic developments, including a 2020 alliance with Gilead Sciences and leadership changes in recent years, and in August 2023 it was acquired by Ikena Oncology in an all-stock transaction.
