Allist will handle the commercialisation of the assets in China and cover subsequent expenditures for their clinical development.

A new drug application for glecirasib monotherapy for second-line non-small cell lung cancer (NSCLC) with KRAS G12C mutation received priority review in May 2024 and breakthrough therapy designation in December 2022 in China.

In April 2024, data from a Phase II study of glecirasib showed a confirmed objective response rate of 47.9% in second-line NSCLC patients.

The disease control rate was 86.3%, with median progression-free survival of 8.2 months and median overall survival of 13.6 months.

The first subject was recently dosed in a Phase III clinical trial of the glecirasib and JAB-3312 combination versus standard care.

In addition to NSCLC, glecirasib is undergoing pivotal studies for second-line or above pancreatic cancer and in combination with cetuximab for colorectal cancer.

Jacobio Pharma chairman and CEO Dr Wang Yinxiang stated: “Allist has strong commercialisation capabilities in the field of lung cancer, and the first indication for glecirasib submitted the new drug application is lung cancer. We believe that with the deep fit of the advantages of both parties, this collaboration will demonstrate great clinical and commercial value.

“In addition to the co-operation with glecirasib, Allist also licensed-in the SHP2 inhibitor JAB-3312, the first SHP2 inhibitor entering a registrational trial globally. It is expected to become a first-line therapy in combo with glecirasib, which reflects Allist’s foresight into the future of pipelines.”
