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 relates to tools and methods for the generation of antibodies which specifically bind chemokine receptors, such as CC or CXC chemokine receptors. Provided are isolated sulfated polypeptides and conjugates thereof, which can be used for example as antigens or for off target panning to facilitate the generation of anti-human, anti-, and/or anti-mouse chemokine receptor antibodies, e.g. for the generation of antibodies with fully human CDRs and/or other favorable properties for therapeutic use. The present invention furthermore relates to antibodies and conjugates thereof which can be obtained by applying the aforementioned tools and methods. Provided are antibodies specifically binding to human,and/or murine CCR8 with favorable properties for therapeutic use, such as cross-reactive antibodies, fully human antibodies, low internalizing (including non-internalizing) antibodies, and antibodies efficiently inducing ADCC and/or ADCP in Treg cells.
