Additional Relevant Details Under the terms of the collaboration agreement, NanoString will be responsible for developing and validating the diagnostic test and, if the parties thereafter determine to proceed, NanoString would also be responsible for seeking regulatory approval for and commercializing the diagnostic test. NanoString is eligible to receive up to $22 million for technology access, near-term milestones and development funding, in addition to other potential undisclosed downstream payments. Under the Collaboration Agreement, NanoString will modify its PAM50-based Prosigna Breast Cancer Assay for potential use as a companion diagnostic test for enzalutamide for triple negative breast cancer. The modified test will be based upon data from a Phase 2 trial conducted by Medivation and Astellas that evaluated enzalutamide in patients with triple negative breast cancer.
