Beijing, Shanghai, Boston, September 23, 2024 – Jacobio Pharma (1167.HK), a clinical-stage oncology company focusing on undruggable targets, today announced that it received IND (investigative new drug) approval from the U.S. FDA of Pan-KRAS inhibitor JAB-23E73, and Jacobio plans to initiate phase I/IIa clinical trial in advanced solid tumor patients. The China IND has been submitted, and China clinical trial will be initiated after China IND approval. 

KRAS is widely present in a variety of tumor mutations. 23%-25% of cancer patients have KRAS mutations. About 2.7 million tumor patients with KRAS-related mutations are added each year worldwide and are expected to benefit from Pan-KRAS inhibitor.

JAB-23E73 can inhibit both the active (“ON”）and inactive (“OFF”) states of KRAS and with no obvious inhibition to HRAS or NRAS. As an oral KRAS inhibitor, JAB-23E73's preclinical data showed good pharmacokinetic profile.
