Peter Edman, Head of R&D, will leave Sobi as of December 31, 2011. "The years in Sobi have been exciting and rewarding", says Peter Edman. "During this time we have restructured and focused the research operations on recombinant protein projects within rare diseases, and taken the decision to advance three development projects into phase III. I have the greatest respect for the knowledge and competence within Sobi and it was not an easy decision to leave." "I want to thank Peter for his contributions to Sobi and we wish him well in his future endeavors" says Geoffrey McDonough, President and CEO of Sobi. "We remain committed to delivering our phase III and early stage development pipeline. We will also utilize our unique competences in protein biochemistry and biologics manufacturing to acquire new late stage assets in the rare disease area. We will now start the process to bring in a senior individual with the appropriate skills to build on this foundation for the future."
