Patent number: 8440200Abstract: Methods for desensitization of a mammal suffering from IgE mediated allergy comprise the steps of: administering to said mammal a therapeutically effective amount of an immunogenic and hypoallergenic composition which comprises (i) a Phl p 6 molecule having an N-terminal truncation which makes the molecule at least lack IgE binding capacity, and/or (ii) a Phl p 6 molecule having a C-terminal truncation which makes the molecule at least lack IgE binding capacity, wherein the molecules of (i) and (ii), if employed in combination, together span the complete sequence of Phl p 6, and a pharmaceutically acceptable carrier.Type: GrantFiled: November 1, 2007Date of Patent: May 14, 2013Assignee: Phadia ABInventors: Rudolf Valenta, Susanne Vrtala, Sabine Stumvoll, Hans Grönlund, Monika Grote, Luca Vangelista, Annalisa Pastore, Wolfgang R.

Patent number: 7482010Abstract: The invention relates to a hypoallergenic immunogenic molecule derived from the Phl p 6 allergen, wherein the Phl p 6 molecule has an N-terminal and/or C-terminal deletion which makes the molecule at least substantially lack IgE binding capacity. The invention also relates to a hypoallergenic immunogenic combination of molecules derived from the Phl p 6 allergen, comprising (i) a Phl p 6 molecule having an N-terminal deletion which makes the molecule at least substantially lack IgE binding capacity, and (ii) a Phl p 6 molecule having a C-terminal deletion which makes the molecule at least substantially lack IgE binding capacity, which two molecules together encompass the complete sequence of Phl p 6. The invention further relates to the use of the hypoallergenic immunogenic molecule or molecule mixture in hyposensitization and diagnosis.Type: GrantFiled: November 27, 2002Date of Patent: January 27, 2009Assignee: Phadia ABInventors: Rudolf Valenta, Susanne Vrtala, Sabine Stummfoll, Hans Grönlund, Monika Grote, Luca Vangelista, Annalisa Pastore, Wolfgang R.

Patent number: 7108858Abstract: The present invention is drawn to an immunogen derived from a protein allergen, which is a) a non-anaphylactic immunogenic recombinant fragment of the protein allergen which contains an IgG epitope partly but not wholly overlapping an IgE epitope of the protein allergen; b) a polymeric form of the fragment, in which the fragment constitutes the monomeric units; or c) a non-anaphylactic recombinant polymeric form of the protein allergen having 2–10 monomeric units, in which the protein allergen constitutes the monomeric units. The present invention is further drawn to the use of the immunogen for in vitro diagnoses of type I allergy and hyposensitization.Type: GrantFiled: July 3, 2001Date of Patent: September 19, 2006Assignee: Pharmacia Diagnostics ABInventors: Rudolf Valenta, Susanne Vrtala, Luca Vangelista, Hans-Georg Eichler, Wolfgang R.
