Jemincare Announces the Exclusive License of the Kras Inhibitor to HUYABIO

SHANGHAI,Nov. 30,2021 -- Jemincare,a leading pharmaceutical company from China,announced today its wholly owned subsidiary company,Shanghai Jemincare Pharmaceutical Co.,Ltd.,had licensed exclusive worldwide ex-China rights to the Kras inhibitor,JMKX1899,to HUYABIO International,the leader in accelerating global development of China's pharmaceutical innovations. Jemincare will retain the relevant rights in greater China area.

Kras is one of the most mutated oncogenes in human cancers. The prevalent G12C mutation drives tumor growth and metastasis and has become an important validated target for therapy especially in lung and colorectal cancer. Targeting the GTP pocket of Kras in the switch-II region,which has made Kras druggable,enables the development of more potent and potentially effective inhibitors.

JMKX1899 is a KRAS inhibitor independently developed by Jemincare. Data from preclinical studies shows it has strong blood-brain-barrier crossing capability and has no risk of hERG inhibition and drug-drug-interaction. Jemincare has filed the IND to NMPA in Oct. 2021. The parties will work closely to file IND in US FDA in 2021 to move towards clinical development.

Mr. Hong Liang,President of Jemincare Pharmaceutical Group,said,"Weare delighted to work with HUYABIO to explore global development of this unique KRAS inhibitor. This is our first new chemical entity program out-licensed to a global partner. HUYABIO has generated a lot of experience to bring innovative drugs from China to global market. We look forward to generating the clinical efficacy and safety data from global clinical trial since the candidate has huge potential to fill strong unmet needs."

Dr. Mireille Gillings,CEO & Executive Chair of HUYABIO,"We are excited to have added the clinical stage Kras inhibitor to our oncology pipeline especially to test in combination with our SHP inhibitor against a variety of solid tumors. We're delighted to have an excellent partner Jemincare to co-develop combinations that can benefit patients worldwide."
