In 2022, Jing Medicine received IND approval for HJM-353, an EED inhibitor, in both China and the United States, however, no clinical study has been initiated as of yet.

In 2021, Jing Medicine filed a patent (WO2022268229) claiming the PROTACs targeting EGFR, ALK, and ROS1.  These CRBN-based PROTACs, designed with Brigatinib analogs that target ALK and EGFR kinases, may offer a potential new approach for treating lung cancer by inducing targeted protein degradation.

E95 and E123 demonstrated potent degradation activity, with DC50 values around single-digit nM and achieving over 90% degradation (Dmax) for EGFR-DTC (Del19/T790M/C797S), EGFR-LTC (EGFR L858R/T790M/C797S), and EGFR-DC (EGFR Del19/C797S).

In 2018, Jing Medicine secured a worldwide licensing agreement with ShanghaiTech University for 6 PROTAC degrader drug candidates, with a total package exceeding $100 million.
