"JAB-21822 is one of Jacobio’s programs targeting on KRAS pathway, we plan to explore the JAB-21822 in colorectal cancer, pancreatic cancer, and other indications. Meanwhile, Jacobio is exploring combination therapies of JAB-21822, such as in combination with SHP2 inhibitor. We are also developing novel drugs in KRAS pathway, including KRASmulti inhibitor (JAB-23400) and KRAS G12D inhibitor (JAB-22000)," said Dr. WANG Yinxiang, Chairman and CEO of Jacobio.
About the Abstract
A phase I/II study of first-in-human trial of JAB-21822 (KRAS G12C inhibitor) in advanced solid tumors.
Format: Poster Presentation
Abstract Number: 3089
Time: Sunday, June 5, 2022 8:00 AM-11:00 AM (CDT)
Track: Developmental Therapeutics – Molecularly Targeted Agents and Tumor Biology
As of January 28th, 2022, 53 patients with a median age of 62 years (39-79) were enrolled in 5 different dose levels: 200mg QD, 400mg QD, 800mg QD, 400mg BID and 400mg TID. A total of 33 patients (22 non-small cell lung cancer, 9 colorectal cancer and 2 pancreatic cancer) had at least 1 post-baseline tumor assessment.
Patients with non-small cell lung cancer (400mg QD and 800mg QD), the overall response rate (ORR) and disease control rate (DCR) were 70% (7/10) and 100% (10/10), respectively.
No dosing-limiting toxicities were observed.
JAB-21822 was well tolerated with impressive preliminary efficacy in patients with heavily treated solid tumors harboring KRAS G12C mutation. The clinical trial is still ongoing and the above data is as of January 28, 2022.
More data will be posted on the poster at the 2022 ASCO (Free ASCO Whitepaper) Annual Meeting, please visit www.asco.org for more information.
