Suzhou China, April 12, 2023 —— Accro Bioscience (Suzhou) Limited announced today that the first subject has been dosed in a phase 1 clinical trial of AC-101 in Australia. AC-101 is a novel oral small-molecule inhibitor of RIPK2 which has been developed for the treatment of IBD. The aim of this trial is to evaluate the safety, tolerability, pharmacokinetics, and food effects of AC-101 in healthy adult subjects. Additionally, biomarker and PK/PD correlation will be explored, providing a scientific basis for the design and dosing regimen of phase II and III clinical trials.
Receptor interacting protein kinase 2 (RIP2 or RIPK2) is a member of the receptor interacting serine/threonine protein kinase family. Dysregulation of NOD/RIPK2 dependent signaling pathways is associated with human diseases, such as inflammatory bowel disease (IBD) and sarcoidosis.
AC-101 was developed from the company's drug discovery platform targeting "regulatory cell death and inflammation". It is the second innovative oral small molecule inhibitor to be launched into clinical trial after AC-003, a potent RIPK1 inhibitor. Preclinical studies show that AC-101 effectively inhibits the release of the NOD-RIPK2 dependent inflammatory factors and significantly protects tissue damage in IBD models. AC-101 is the leading RIPK2 asset worldwide. The current IBD treatments have many adverse factors: the serious side effects associated with long-term use of glucocorticoids, drug/drug interactions, long-term toxicity for immunosuppressants, and the loss of efficacy in some patients with biological agents. An oral drug with novel mechanism of action may provide solution to the unmet medical needs for patients suffering from IBD.
Dr. xiaohu Zhang, Co-founder and CEO of Accropeutics Bioscience, said: “AC-101 displays high activity and selectivity with wide safety window. It has the potential to become an effective treatment for IBD patients. We will work diligently to move the program forward, and hope AC-101 will one day help IBD patients worldwide.”
