Sage Bionetworks, the Seattle-based nonprofit seeking to spark an open source movement for biology, said today it has begun work for a couple of partners—Japan-based Takeda Pharmaceutical and the CHDI Foundation. Both projects involve building computational models for neurological diseases. Takeda said it November that it agreed to pay $3.6 million over four years to support the research. Sage didn’t disclose the terms of CHDI’s support in today’s statement, although Sage said it is working with Massachusetts General Hospital to analyze tissues from Huntington’s disease patients. Sage also recently received support from pharmaceutical giant AstraZeneca to perform cancer research.
