“Todd is a senior healthcare executive with two decades of commercial experience in both primary care and specialty markets, which makes him ideally suited to lead our commercial team,” said Gustav Christensen, President and Chief Executive Officer of Dyax. “His strong track record of strategic leadership, operational execution, and launching and developing brands will be highly valuable as we aim to grow our KALBITOR business and as we develop plans for how to optimize the value of DX-2930 which is currently in clinical development.”

Mr. Bazemore stated, “It's a privilege to join the Dyax team during this important time as we continue to successfully commercialize KALBITOR and develop our future plans for DX-2930. I'm excited about the opportunity we have to truly help both the patients suffering from HAE and the physicians that treat them.”

About Dyax
