Aravive Biologics and WuXi Biologics to Form Strategic Manufacturing Collaboration Following Successful IND Filing for AVB-S6-500

HOUSTON & WUXI, China

Aravive Biologics, Inc. and WuXi Biologics (WuXi Bio, 02269.HK) today announced plans to expand their biologics manufacturing collaboration, based on the rapid success achieved in the process development, scale-up and cGMP manufacture of Aravive’s lead drug candidate, AVB-S6-500 (previously referred to as Aravive-S6). The decision follows the successful filing of a U.S. Investigational New Drug application (IND) for AVB-S6-500, a novel GAS6-AXL pathway inhibitor which Aravive is developing for the treatment of cancer and non-malignant fibrotic conditions.

“Since selecting WuXi Biologics to produce our lead therapeutic candidate for preclinical studies, our efforts with the firm on the production and scale-up of AVB-S6-500 have been extremely successful, quickly advancing from plasmid to U.S. IND in less than 16 months,” said Ray Tabibiazar, M.D., Aravive’s Chairman. “We look forward to building on our relationship with WuXi Biologics as we move forward with our plans to advance AVB-S6-500 into clinical testing and expand the Aravive pipeline over the coming years.”

“We are very pleased to be part of the continuing development of AVB-S6-500 and are excited about the potential that this first-in-class molecule has shown to date as an innovative new therapy for people with cancer and fibrotic disease,” said Dr. Chris Chen, Chief Executive Officer of WuXi Biologics. “We also look forward to collaborating with Aravive over the coming years on further molecules in their pipeline. Aravive’s desire to continue and build upon its relationship with WuXi Biologics is a strong validation of the premier quality and global excellence of our services. We strive to make life-saving biologics more affordably produced and available to patients around the world.”

In August 2017, WuXi Biologics’ cGMP facility at Wuxi city was the first China-based manufacturing facility to complete a U.S. Food and Drug Administration (FDA) Pre-License Inspection for any biologics drug under FDA review, which paved the way for biologics commercial manufacturing.

About AVB-S6-500

AVB-S6-500 is a novel biologic drug candidate that neutralizes GAS6 with high affinity and is designed to inhibit the GAS6-AXL signaling pathway. Research has shown GAS6-AXL signaling to be a key molecular pathway that is believed to promote tumor growth and metastasis, as well as tumor immune evasion and resistance to other anticancer agents. In preclinical studies, GAS6-AXL inhibition has shown both single agent activity and synergies with a variety of anticancer therapies including radiation therapy, immuno-oncology agents, and drugs that affect DNA replication and repair. Aravive expects to initiate a Phase 1 clinical trial of AVB-S6-500 in the first quarter of 2018.
