  • Publication number: 20220023420
    Abstract: A fusion protein comprising: a first component comprising an antibody, or a fragment or variant thereof; and a second component comprising a cytokine trap or an adenosine deaminase or a fragment or variant thereof. In certain embodiments, the antibody is an anti-PD-1 antibody. In certain embodiments, the antibody binds to a tumor antigen, for example a MUC16 or MUC1 antigen. In certain embodiments, the cytokine trap is a TGF-? trap. A polynucleotide encoding such a fusion protein and a vector comprising such a polynucleotide. A composition comprising the fusion protein. A method of using the composition, including in the treatment of cancer.

  • Publication number: 20180251548
    Abstract: The present disclosure relates the combined effect of anti-CD155 [CD155, Nectin-like protein 5 (Nec1-5), Tage4, HVED, poliovirus receptor (PVR)] antibodies or anti TIGIT antibodies [TIGIT (T cell immunoreceptor with Ig and ITIM domains), WUCAM (Washington University cell adhesion molecule), Vstm3 (V-set and transmembrane domaincontaining protein 3), Vsig9 (V-set and immunoglobulin domain-containing protein 9)] with a TGF Beta 1 antagonist. The effect is measured by increased IFN-gamma production human breast adenocarcinoma cells. Use of combined antibodies /CD155 or TIGIT) with a TGF-Beta 1 antagon-ist to treat a patient with cancer is claimed.

  • Publication number: 20140308294
    Abstract: The invention relates to polypeptides that block or inhibit the interleukin-1 receptor 1 (IL-1R1), the interaction of IL-1beta with IL-1R1 or the interaction between IL-1R1 and interleukin-1 receptor accessory protein (IL-1RaCP). The invention relates specifically to therapeutic polypeptides that target specifically IL-1R1 present on tumor cells, cancer stem cells, and cancer stem cells which are resistant to chemotherapy or radiotherapy. The invention specifically relates to cancer stem cells (CSC) that express IL-1R1 to which said inhibitors bind. Finally the invention relates to a combination therapy comprising killing tumorigenic differentiating cancer cells by means of standard chemo- or radiotherapy and prior or subsequent to that applying IL-1R1 inhibitors which target specifically CSC and strip the tumor of its capacity to generate cancer cell progeny.
