Professor Trevor M. Jones CBE, president of Sigma Tau USA Inc., said, "We are delighted to appoint Dave to this new position. His appointment comes at a pivotal time in the development of the company, as it now expands via commercialization of its proprietary internal R&D pipeline, and the pursuit of externally driven growth opportunities. The appointment of the chief executive role reflects the commitment Sigma Tau USA Inc. has to the field of rare diseases, and to the significant impact we expect these medicines will ultimately have on their respective physician and patient communities, alike."
