Swiss-Japanese ADC player Araris expands Chugai pact with $780m licensing agreement
Zurich-based oncology biotech Araris Biotech AG has entered into a research collaboration with an option to license with Japan’s Chugai Pharmaceutical, a subsidiary of Roche. The aim of the partnership is to develop next-generation antibody–drug conjugates (ADCs). While Araris itself is now Japanese-owned – a wholly owned subsidiary of Taiho Pharmaceutical, part of the Otsuka Group – its research activities remain firmly rooted in Zurich. That presence was highlighted last year when the Strüngmann brothers, German billionaire twins, awarded a prize to the company’s founders.
