According to public data, Aurora kinase is a serine/threonine protease that regulates cell mitosis
Studies have shown that the combination of Aurora A inhibitor and KARS G12C inhibitor can overcome the latter's resistance, and has a synthetic lethal effect with RB1 gene deletion or inactivation, and can be used for the treatment of small cell lung cancer and triple-negative breast cancer.
According to public information, in addition to JS112, Junjing Bio has a number of drugs that have been approved for clinical trials in China
The other is the XPO1 inhibitor WJ01024 tablets (project code JS110), which is a small molecule inhibitor of the nuclear export protein XPO1, which can inhibit the nuclear export of various tumor suppressor proteins including p53 and enhance the function of tumor suppressor proteins
According to the cooperation agreement reached between Junshi Bio and Weijing Bio in 2020, Junshi Bio will obtain 50% of the rights and interests of the four drugs under development of Weijing Bio, as well as the exclusive production rights and entrusted production worldwide after approval.
This time, the Aurora A inhibitor JS112 has been approved for clinical use, which means that the cooperation between Junshi Bio and Microenvironment has ushered in new progress
