  • Patent number: 11597777
    Abstract: The invention relates to an isolated monoclonal antibody that specifically binds to the D4 domain of VWF, competes for binding to VWF D4 domain with ADAMTS13 and partially inhibits ADAMTS 13-mediated degradation of VWF. More particularly, the invention relates to an isolated monoclonal antibody comprising a heavy chain wherein the variable domain comprises at least one CDR having a sequence selected from the group consisting of SEQ ID NO: 3 for H-CDR1, SEQ ID NO: 4 for H-CDR2 and SEQ ID NO: 5 for H-CDR3 and a light chain wherein the variable domain comprises at least one CDR having a sequence selected from the group consisting of SEQ ID NO: 7 for L-CDR1, SEQ ID NO: 8 for L-CDR2 and SEQ ID NO: 9 for L-CDR3. Antibodies of the invention are presented to be useful in for the prevention or the treatment of bleeding episodes, such as bleeding episodes occurring in patients with aortic stenosis or patients with ventricular assist devices (VAD).

  • Publication number: 20210277145
    Abstract: The present invention relates to a peptide comprising the amino acid sequence QGLIGDIALPRWGALWGDSV (SEQ ID NO: 1). Inventors have tested in wild-type mice a single domain antibody directed against VWF and tagged with an albumin-binding peptide. After giving a single dose intravenously (50 microgram/mouse), VWF levels were increased 8-15 fold for at least 7 days, knowing that the half-life of VWF is about 2-3 hours in a mouse. Moreover, intravenous administration of VWF together with a sdAb fused to an albumin-binding peptide resulted in detectable levels of VWF at 48 and 72 hours after injection, whereas no VWF could be detected when injected in the absence of such sdAb fused to an albumin-binding peptide. Thus, these results show a very long-lasting effect of this new approach.

  • Patent number: 10443349
    Abstract: A well tool apparatus comprises a control arrangement configured to control response of the downhole tool by varying downhole drilling fluid conditions. The control arrangement includes a valve piston longitudinally slidable in a generally tubular controller housing that is in operation substantially co-axial with the wellbore, to open or close a valve port to a fluid flow connection between the drill strings interior and the tool. A latch mechanism is configured to latch the valve piston in an activated mode and/or a deactivated mode. Unlatching of the valve piston can be effected by displacement thereof in a particular axial direction to a mode change position. A stay member is automatically displaceable in the particular actual direction under hydraulic actuation responsive to above-threshold drilling fluid conditions, to obstruct movement of the valve piston under hydraulic actuation to the mode change position.

  • Publication number: 20190100602
    Abstract: The present invention relates to isolated single-domain antibodies (sdAb) directed against Antithrombin (AT) to prolong the half-life of the proteins. Inventors have generated isolated single domain antibodies (sdAbs) directed against antithrombin. They observed that in amidolytic assays, sdAbs are incapable of blocking the inhibitory antithrombin activity towards thrombin and factor Xa in the presence of heparin. The different combinations of sdAb were able to block the inhibitory antithrombin activity towards thrombin and factor Xa in mice. Thus, the inventors propose to use different combinations of sdAb to block the inhibitory function of antithrombin in order to promote thrombin generation and thus treat haemophilia and other conditions that are associated with bleeding.
