The present disclosure relates to an isolated antibody or antigen-binding fragment thereof that binds to human Semaphorin 3A (Sema3A). An antibody conjugate and a pharmaceutical composition each comprising the isolated antibody or antigen-binding fragment thereof that binds to human Sema3A are also provided.

Anti-semaphorin 3A antibodies

The present disclosure relates to an isolated antibody or antigen-binding fragment thereof that binds to human Sema3A. The isolated antibody or antigen-binding fragment according to the present disclosure i) binds to human Sema3A of the sequence of SEQ ID NO: 600 with a dissociation constant (KD)≤50 nM, ≤20 nM, ≤10 nM, ≤1 nM, or ≤0.1 nM; ii) cross-reacts with mouse, cynomolgus, rat, pig and/or dog Sema3A, particularly wherein said isolated antibody or antigen-binding fragment thereof binds to mouse, cynomolgus, rat, pig and/or dog Sema3A with a dissociation constant (KD)≤50 nM, ≤20 nM, ≤10 nM, ≤1 nM, or ≤0.1 nM; iii) binds to human Sema3A of the sequence of SEQ ID NO: 600 with a binding activity as measured by surface plasmon resonance (SPR) of ≥60%, ≥70%, ≥80%, or ≥90%; iv) inhibits the activity of human Sema3A of the sequence of SEQ ID NO: 600 in an in vitro mesangial cell migration assay with an EC50 of ≤10 nM, ≤5 nM, ≤2.5 nM, or ≤1 nM; v) inhibits the activity of human Sema3A of the sequence of SEQ ID NO: 600 in an in vitro growth cone collapse assay with an EC50 of ≤50 nM, ≤25 nM, ≤10 nM, or ≤5 nM; vi) inhibits the activity of human Sema3A of the sequence of SEQ ID NO: 600 in an in vitro HUVEC repulsion assay with an EC50 of ≤1 nM, or ≤0.3 nM, ≤0.1 nM, ≤0.07 nM, ≤0.06 nM and/or vii) exhibits an increased potency against cellular Sema3A, of the sequence of SEQ ID NO: 600, induced HUVEC repulsion.

Anti-sema3a antibodies and uses thereof

The present invention is related to short-term renal injury models and methods for creating these models. The models and methods can be used for identifying, testing or characterizing candidate molecules with respect to their suitability to treat renal injury. The methods comprise a step of inducing, in a test subject, renal injury by administering subcutaneously a bolus of a renal injury inducer, in a dosage sufficiently high to induce renal injury. Different types of readout for renal injury are provided such as albumin creatinine ratio (ACR) determined in a urine sample taken from the subject, or the development of transcutaneous fluorescence after injection of a fluorescent molecule. Based on the readout the degree of renal injury and/or alteration of GFR can be determined.

Method for creating a renal injury model to screen molecules for the treatment of renal injury

The present invention relates to novel 5-(carboxamide)-1-phenyl-1,2,4-triazole derivatives, to processes for the preparation of such compounds, to pharmaceutical compositions containing such compounds, and to the use of such compounds or compositions for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of renal and cardiovascular diseases.

Amide-substituted phenyltriazole derivatives and uses thereof

The present invention relates to novel 5-(carboxamide)-1-pyridinyl-1,2,4-triazole derivatives, to processes for the preparation of such compounds, to pharmaceutical compositions containing such compounds, and to the use of such compounds or compositions for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of renal and cardiovascular diseases.
