Jacobio’s Preclinical Results of KRAS G12C Inhibitor in Combination with SHP2 Inhibitor Will be Presented at the ESMO Asia Congress 2022

Dec 2, 2022

Beijing, Shanghai, Boston, Dec.2, 2022—Jacobio Pharma (1167.HK) will present the results of KRAS G12C inhibitor JAB-21822 as a single agent or in combination with SHP2 inhibitor JAB-3312 in preclinical cancer models in a poster session during the 2022 European Society of Medical Oncology ASIA (ESMO ASIA) Congress from December 2, 2022 to December 4, 2022.

The results of preclinical study showed that JAB-21822 in combination with JAB-3312 could
synergistically inhibit tumor growth in multiple KRAS G12C inhibitor-resistant models, suggesting that the combination of JAB-21822 and JAB-3312 may overcome adaptive resistance to KRAS G12C inhibitor in cancer patients. Jacobio is currently conducting a clinical trial of JAB-21822 in combination with JAB-3312 (ClinicalTrials.gov Identifier: NCT05288205).
