Anti-CCL2 and anti-LOXL2 combination therapy for treatment of scleroderma
The present invention provides, among other things, bi-specific molecules including, but not limited to, antibodies, fynomers, aptamers, fusion proteins, and protein binding domains that bind both CCL2 and LOXL2 and uses thereof, in particular, for treatment of scleroderma and related fibrotic and/or inflammatory diseases, disorders and conditions. In some embodiments, the present invention further provides methods and compositions for treatment of scleroderma and related fibrotic and/or inflammatory diseases, disorders and conditions based on the combination of mono-specific anti-CCL2 and anti-LOXL2 molecules.
1. A method of treating human skin ulcers due to scleroderma comprising administering to a human subject having skin ulcers due to scleroderma a therapeutically effective amount of
an anti-CCL2 antibody, or fragment thereof, that binds to human CCL2 protein; and
an anti-LOXL2 antibody, or fragment thereof, that binds to human LOXL2 protein,
wherein the administration leads to reduced skin ulcers in the human subject relative to an untreated human subject individual who has skin ulcers due to scleroderma.
2. The method of claim 1 , wherein the anti-CCL2 antibody, or fragment thereof, has a binding affinity of 1 pM or greater.
3. The method of claim 1 , wherein the anti-LOXL2 antibody, or fragment thereof is selected from the group consisting of intact IgG, F(ab′)2, F(ab)2, Fab′, Fab, ScFvs, diabodies, triabodies and tetrabodies.
4. The method of claim 1 , wherein one or both of the anti-CCL2 antibody, or fragment thereof, and the anti-LOXL2 antibody, or fragment thereof, are humanized.
