About Us

Where science meets the will to fight

Our products come from years of research and development performed by world-renowned immunologists—our founders, Yang Liu, PhD, and Pan Zheng, MD, PhD.

Anchored by a team of business strategists and operations leaders with a proven history of getting products through clinical development, we are poised to offer patients battling evasive cancers a more promising path forward.
