IBD98-M is a combination therapy drug developed with the Hyaluronan Drug Delivery (HDD) technology platform of Holy Stone Healthcare. IBD98-M is an anti-inflammatory drug for the treatment of ulcerative colitis, which is manufactured by a patented process of combining 5-aminosalicylic acid (5-ASA) and hyaluronic acid. The special pharmaceutical design allows the 5-ASA to release at the proximal end of the colon. Meanwhile, hyaluronic acid inhibits inflammation through CD44 related signal pathway, and the viscoelasticity of hyaluronic acid forms a soft barrier to protect the inflamed sites from the irritations of gut microbes and other external factors. IBM98-M also increases the local concentration and bioavailability of 5-ASA in the inflamed site of the colon and enhance the anti-inflammation effects.

In this agreement, Holy Stone Healthcare and Gongwin Biopharm will collaborate on conducting IBD98-M Phase II Clinical Trial in China. Both parties will invest funds and manpower in this case. The remarkable experience of Gongwin Biopharm in conducting clinical trials in China, as well as its vast networks will benefit the planning and conducting of future clinical trials. In addition, both parties will cultivate the licensing opportunities in the China market to create a new era and share the profits.
