Mr. Platshon will serve as Executive Vice President and Chief Business Officer and continue to lead Zymeworks’ asset aggregation strategy while managing expected future cash flows from Ziihera® (zanidatamab-hrii) and other licensed healthcare assets, including pasritamig, which is being advanced into Phase 3 registration studies by Johnson & Johnson Innovative Medicine. In his full-time role as Chief Business Officer, he is responsible for executing Zymeworks’ strategy to build and actively manage a diversified portfolio of revenue-generating assets to help drive long-term shareholder value.
Dr. Schayowitz and Mr. Platshon both join the executive leadership team from EcoR1 Capital, a significant shareholder in Zymeworks.
