ArriVent Announces Multi-Target ADC Collaboration With Alphamab


ArriVent BioPharma, Inc. recently announced it has entered into a collaboration agreement with Jiangsu Alphamab Biopharmaceuticals Co., Ltd. to discover, develop and commercialize novel antibody drug conjugates (ADCs) for the treatment of cancers.

“This exciting collaboration strengthens and complements our pipeline with the potential to add multiple innovative new ADC programs and exemplifies our strategic model of identifying and developing potential first-and best-in-class product candidates from across the globe,” said Bing Yao, Chairman and Chief Executive Officer of ArriVent. “We look forward to complementing the research and discovery capabilities of Alphamab with our global drug development and commercialization expertise to address the unmet needs of cancer patients.”

“ArriVent shares our passion for developing differentiated, clinically valuable, and globally competitive new drugs,” said Ting Xu, PhD, Founder, Chairman, and CEO of Alphamab Oncology. “This collaboration, based on Alphamab’s proprietary and clinically validated glycan-conjugation platform, combined with ArriVent’s deep knowledge in oncology and extensive development experience, provides us with the opportunity to work together to deliver important new oncology therapeutics to patients.”

Under the agreement, both companies will leverage Alphamab’s proprietary linker-payload platform and glycan-conjugation technology to identify novel ADCs for oncology indications. The agreement gives ArriVent exclusive rights to develop and commercialize ADCs globally, except greater China, which includes outside of mainland China, Hong Kong, Macau and Taiwan where Alphamab retains the right to develop and commercialize the ADCs.

The terms of the agreement include combined upfront and potential milestone payments to Alphamab of up to $615.5 million in aggregate for the potential programs, based on the achievement of certain regulatory, development, and sales milestones. In addition, Alphamab is entitled to receive tiered sales royalties from ArriVent for each ADC product.
