Publication number: 20210171631Abstract: The present invention relates to the identification of fibrinogen like protein 1 (FGL1) as a prognostic biomarker for responsiveness to an immune checkpoint inhibitor in a cancer patient. More specifically it relates to methods of treating cancer in a human patient comprising administering an immune checkpoint inhibitory antibody specifically inhibiting the interaction of fibrinogen-like protein 1 (FGL1) with lymphocyte-activation gene 3 protein (LAG3), wherein the cancer is an FGL1 expressing cancer. Further, the invention relates to methods for assessing susceptibility or predicting the responsiveness to the treatment with an immune checkpoint inhibitory antibody specifically inhibiting the interaction of FGL1 with LAG3 in a cancer patient, comprising detecting FGL1 expression in a sample from said patient and to a kit for selecting a cancer patient that would benefit from an immune checkpoint inhibitory antibody specifically inhibiting the interaction of FGL1 with LAG3.Type: ApplicationFiled: June 10, 2019Publication date: June 10, 2021Inventors: Lieping CHEN, Jun WANG, David A.

Patent number: 10330221Abstract: A piping system includes a first and a second inner tube assembled end to end and a hot fluid detector. For each inner tube, a first peripheral tube into which the inner tube is introduced and fixed. For each first peripheral tube, a second peripheral tube into which the first peripheral tube is introduced and fixed. A sleeve has a first section which surrounds the ends of the second two peripheral tubes facing one another and a second section which extends between the two ends up to the walls of the first two peripheral tubes. A pipe crosses the sleeve and opening out, on the one hand, into the space between the inner tubes and the first peripheral tubes and, on the other hand, in the vicinity of the hot fluid detector. A piping system of this kind is therefore thermally insulated and allows detection in the event of a leak.Type: GrantFiled: August 31, 2017Date of Patent: June 25, 2019Assignee: AIRBUS OPERATIONS (S.A.S.)Inventors: Olivier Verseux, David Blain

Patent number: 10215222Abstract: A universal joint comprising a first band, a second band, and a third band. The three bands are cylindrical bands coaxial with one another with respect to a common axis. The first band and the second band are separated by a first slot, and the second band and the third band are separated by a second slot. Two connection points, which are diametrically opposed, assure the connection of the first band and of the second band. Two other connection points, which are diametrically opposed, assure the connection of the second band and of the third band. The two connection points between the first band and the second band are offset by substantially 90° in rotation about the common axis with respect to the two connection points between the second band and the third band.Type: GrantFiled: March 9, 2016Date of Patent: February 26, 2019Assignee: AIRBUS OPERATIONS SASInventor: David Blain
