Messenger RNA, an intermediate messenger that carries the instructions for making proteins, plays a fundamental role in biology, enabling rapid translation of the desired protein in cells. mRNA medicines utilize natural physiological processes to express required proteins for preventing or curing diseases. The mechanism of mRNA drugs makes it possible to treat a range of diseases, including those that are currently untreated.

Based on Stemirna’s mRNA synthesis platform and LPP delivery platform, we have developed a pipeline that spans different therapeutic areas, including immuno-oncology, infectious diseases and iPSC.
