Interim Report January - March 2011

Good volume growth and a 10% increase in revenues despite negative currency
effects and full impact of earlier price reductions

Kennet Rooth, CEO: "We had a good volume growth for ReFacto® during the quarter
as well as for most of our other important products, particularly Kineret® in
the US and in several European markets, and Orfadin® in North America. Both
revenues and profits were negatively affected by currency effects, and the
mandatory price reductions in 2010 have now had full impact. This year we have
not seen the same delays in reimbursements as in 2010 and there have been no new
price reduction requirements.

We are continuing to work on strengthening our company long-term. At the end of
March we announced a number of cost reduction measures. At the same time we are
increasing our focus on business development. The ongoing clinical development
projects are continuing according to plan. Recruitment of patients for phase III
studies for both of the hemophilia programs is under way. We expect the first
patients for the phase III study of Kiobrina® to be recruited in the second
quarter.

  * Net revenues increased by 10% to SEK 537.4 M (488.1). After adjustment for
    currency effects, the increase was 17%.
  * Gross margin was negatively affected by a lower production margin for
    ReFacto®, costs for transfer of Kineret® production, currency effects and by
    the 2010 price reductions having full impact.
  * Administrative and R&D expenses declined by 23% from the previous year.
  * Operating income (EBITA) before non-recurring items improved by 8% to SEK
    59.7 M (55.1). Non-recurring items amounted to SEK 70 M (47) and refer to
    previously announced cost-reduction measures.
  * The Board has resolved, subject to approval by the AGM, on a rights issue of
    approximately SEK 600 M with preferential rights for the company's
    shareholders.
