Symphogen and Swedish Orphan Biovitrum receive U.S. orphan drug designation for Rozrolimupab in ITP

October 6, 2010

COPENHAGEN, Denmark and Stockholm, Sweden – Symphogen and Swedish Orphan Biovitrum (STO:SOBI)  today announced that the United States Food and Drug Administration (FDA) has granted orphan drug designation to rozrolimupab (Sym001) for the treatment of primary Immune Thrombocytopenia (ITP).

An FDA Orphan Drug designation provides tax benefits and an exemption from user fees, eligibility for grant funding, the opportunity of protocol assistance, the possibility to receive a fast track and expedited review process, as well as a seven-year period of market exclusivity after product approval.

ITP is an autoimmune bleeding disorder characterized by abnormally low platelet levels, making it difficult for the blood to clot normally.

“Orphan drug designation provides us with valuable regulatory support for the development of Sym001 in ITP that will be beneficial in our ambition to develop this innovative treatment for chronic ITP patients and provide an alternative treatment to them,”

says Peter Edman, Chief Scientific Officer, Swedish Orphan Biovitrum.

“Sym001 is the first ever recombinant polyclonal antibody product to have entered human clinical trials,”

stated Kirsten Drejer, PhD., Chief Executive Officer of Symphogen.

“Sym001 is cur-rently being studied in a Phase II dose finding trial. We intend to develop it as an alternative to plasma derived anti D and immunoglobulins”.

About Sym001

Rozrolimupab (Sym001) is a recombinant polyclonal composition of 25 different Rhesus D specific antibodies for the treatment of primary Immune Thrombocytopenia (formerly designated Idiopathic Thrombocytopenic Purpura) (ITP) and for Anti-RhD prophylaxis (ADP) in prevention of Hemolytic Disease of the Newborn. In February 2008, Symphogen and Biovitrum reported results from a Phase I dose-escalation, placebo-controlled trial, demonstrating that Sym001 was safe and well tolerated.  In November 2008 Symphogen and Biovitrum reported the results of a clinical study which demonstrated proof of concept in healthy volunteers. The results showed that Sym001 cleared the RhD-positive red blood cells and that the clearance was dose dependent. The ongoing phase II clinical trial evaluates the safety and efficacy, and explores the dose range of Sym001 in immune thrombocytopenia patients.
