  • Patent number: 11291711
    Abstract: Subjects of the invention are a method of plasminogen supplementation in a plasminogen-deficient subject, and method for the treatment of plasminogen-deficiency in a plasminogen-deficient subject. These methods comprise administering to the plasminogen-deficient subject a dose of plasminogen, and more particularly Glu-plasminogen, for increasing the subject plasminogen activity level by at least about 1%, and more particularly by at least 10%, of the normal plasminogen activity and for maintaining the plasminogen activity level over a supplementation period or a treatment period. The plasminogen-deficient subject of the present invention may suffer from Type-I, Type-II plasminogen-deficiency or an acquired deficiency.

  • Publication number: 20090175821
    Abstract: A method for protecting a peptide from peptidase activity in vivo, the peptide being composed of between 2 and 50 amino acids and having a C-terminus and an N-terminus and a C-terminus amino acid and an N-terminus amino acid is described. In the first step of the method, the peptide is modified by attaching a reactive group to the C-terminus amino acid, to the N-terminus amino acid, or to an amino acid located between the N-terminus and the C-terminus, such that the modified peptide is capable of forming a covalent bond in vivo with a reactive functionality on a blood component. In the next step, a covalent bond is formed between the reactive group and a reactive functionality on a blood component to form a peptide-blood component conjugate, thereby protecting said peptide from peptidase activity. The final step of the method involves the analyzing of the stability of the peptide-blood component conjugate to assess the protection of the peptide from peptidase activity.

  • Patent number: 7256253
    Abstract: A secretin or secretin derivative protected against peptidase activity. The secretin or derivative comprises a peptidic sequence and a reactive group selected from the group consisting of succinimidyl and maleimido groups capable of reacting with an amino group, hydroxyl group or thiol group on a blood component to form a stable covalent bond. The reactive group is attached at a position along the peptidic sequence that provides, when conjugated to a blood component, a higher stability against peptidase degradation than the unconjugated secretin or derivative, and therefore an increased maintenance of the therapeutic activity compared to the unconjugated secretin or derivative. Such a compound is thus effective to provide a source of secretin having a high stability against peptidases. A method for synthesizing such a compound is also described.
