Modular, controlled single chain variable fragment antibody switch
11485789 · 2022-11-01 · ·

A modular, small molecule regulated single chain variable fragment (scFv) fusion protein is disclosed. The scFv fusion protein comprises a ligand binding protein fused to a protein that binds to an exogenous control molecule, wherein the scFv fusion protein is directly regulated by the control molecule. Binding of the control molecule to the ligand binding protein induces a change in the affinity of the scFv for a target antigen. Methods of using the fusion protein to treat diseases such as cancer are also described.

20220340650 · 2022-10-27 ·

Disclosed are methods for treating headache, migraine and related symptoms by administering a long acting calcitonin gene related peptide (CGRP) antagonist and a short acting CGRP antagonist. Specifically, the disclosure provides a method for treating, preventing, alleviating, or reducing the frequency of occurrence of headache in a patient in need thereof, comprising administering to the patient: (a) a first calcitonin gene related peptide antagonist (CGRP antagonist) and (b) a second CGRP-antagonist, wherein the first CGRP antagonist is an antibody, and the second CGRP antagonist has a plasma half-life in humans of at most about 60 hours.

Highly sensitive particle enhanced assay for the quantification of NT-proBNP

NT-proBNP can be determined in a biological sample using at least one antibody which recognizes an epitope of NT-proBNP in both a glycosylated and non-glycosylated form of NT-proBNP. Said antibody is preferably an isolated polyclonal antibody or a mixture of monoclonal antibodies coated onto a particle, preferably coated onto said particle in a coating ratio of 6-60%, forming a layer or multiple layers of antibodies on said particle. The assay, realized in the form of a nephelometric or turbidimetric assay, can be applied to a wide range of automated clinical analyzers.

ANTI-PACAP ANTIBODIES AND USES THEREOF

The present invention is directed to antibodies and antigen binding fragments thereof having binding specificity for PACAP. The antibodies and antigen binding fragments thereof comprise the sequences of the V.sub.H, V.sub.L, and CDR polypeptides described herein, and the polynucleotides encoding them. Antibodies and antigen binding fragments described herein bind to and/or compete for binding to the same linear or conformational epitope(s) on human PACAP as an anti-PACAP antibody. The invention contemplates conjugates of anti-PACAP antibodies and binding fragments thereof conjugated to one or more functional or detectable moieties. Methods of making said anti-PACAP antibodies and antigen binding fragments thereof are also contemplated. Other embodiments of the invention contemplate using anti-PACAP antibodies, and binding fragments thereof, for the diagnosis, assessment, and treatment of diseases and disorders associated with PACAP and conditions where antagonism of PACAP-related activities, such as vasodilation, photophobia, mast cell degranulation, and/or neuronal activation, would be therapeutically beneficial.

ANTI-MÜLLERIAN INHIBITING SUBSTANCE ANTIBODIES AND USES THEREOF

In ovarian carcinoma, Müllerian Inhibiting Substance (MIS) type II receptor (MISRII) and the MIS/MISRII signaling pathway are potential therapeutic targets. Conversely, the role of the three MIS type I receptors (MISRI; ALK2, ALK3 and ALK6) in this cancer needs to be clarified. Using four ovarian cancer cell lines and ovarian cancer cells isolated from patients' tumor ascites, the inventors found that ALK2 and ALK3 are the two main MISRIs involved in MIS signaling at low and high MIS concentrations, respectively. Moreover, high MIS concentrations were associated with apoptosis and decreased clonogenic survival, whereas low MIS concentrations improved cancer cell viability. Finally, the inventors showed that anti-MIS antibody B10 inhibited MIS pro-survival effect. These last results open the way to an innovative therapeutic approach to suppress MIS proliferative effect, instead of administering high doses of MIS to induce cancer cell apoptosis.
