Zhejiang Medicine at work with Ambrx on PhI breast cancer candidate

Hangzhou-based Zhejiang Medicine, or ZMC, has started Phase I work in Australia and New Zealand on an antibody candidate targeting HER2-positive breast cancer with San Diego-based Ambrx, building on a 2013 partnership.

The development costs for the Oceania leg will be covered by ZMC, which has also filed with the China FDA to hold trials in China where it holds rights to the candidate, ARX788, according to a press release.

China's top CRO WuXi PharmaTech will handle the development plan for the China leg while ZMC plans to make the drug in China and also for any Ambrx in the case of development outside of China.

"This is the first exciting step to demonstrate the clinical application of our proprietary EuCODE technology for the improvements of cancer patient lives," Ambrx CEO Alex Qiao said in the release.
