Under the terms of the agreement, Sutro will receive an upfront payment of $40 million and be eligible to receive potentially up to $345 million in development and commercial milestone payments. Tasly will pursue the clinical development, regulatory approval, and commercialization of STRO-002 in Greater China for ovarian and endometrial cancers, with the potential to expand to further oncological indications including non-small cell lung cancer (NSCLC) and triple-negative breast cancer (TNBC). Sutro retains development and commercial rights of STRO-002 outside of Greater China. Sutro will be responsible for the clinical trial and initial commercial supply of STRO-002 for trials in the licensed territory pursuant to a supply agreement according to customary terms. Upon commercialization, Sutro will receive tiered, double-digit royalties based on annual net sales of STRO-002 in Greater China.

Kaijing Yan, Chairman of the Board, said, "We are delighted to gain access to this promising drug, which has the potential to be the best-in-class FolRα ADC for patients with debilitating cancers, including ovarian cancer and potentially FolRα-expressing cancers. There is a huge unmet need for oncology patients within Greater China and we look towards future development and commercialization of STRO-002 to serve these needs."

Bill Newell, Chief Executive Officer of Sutro added, "This agreement further validates our emerging clinical data surrounding the development of STRO-002. Tasly is an excellent partner for our Greater China collaboration, with a history of successful execution for developing and commercializing therapeutics. We are delighted to broaden the geographical footprint of STRO–002 and allow greater access for cancer patients to a new possible treatment option."
