CEO comments:"I am pleased to report that Biovitrum has now been transformed from a research company into an international pharmaceutical company, which is reflected by a strong operating result for the first quarter. Important contributors are the sales of Kineret and Kepivance which were slightly better than our forecast for the period. The change in the direction of our research is fully completed and is now focused on biotechnological, specialist pharmaceuticals. The agreement with Affibody is a good example of this focus. We have succeeded in implementing these necessary and comprehensive changes while maintaining our strong financial position," says CEO Martin Nicklasson. "We are also positive to having Investor AB, who has a great deal of experience in the health care sector, as a new main share holder."
