The Shanghai-based company was formed in March 2017 through the merger of Third Venture Biotech and Tasgen Bio, combining their immuno-oncology and immuno-inflammation drug development capabilities. In June 2018, I-Mab closed a $220 million Series C funding round led by Hony Capital and including investors Hillhouse Capital, Hopu Investments, CDH Investment, Ally Bridge Group, C-Bridge Capital, and Singapore state-owned EDBI. The company had a pipeline of more than 10 drugs in development at the time and planned to use Series C proceeds to advance clinical development of its assets in China and internationally.
