The monoclonal IgG-type antibodies were suggested comprising variable domains represented by a combination of VHH-derivative with a variable domain of the light chain V. Said antibodies can comprise amino acid substitutions at positions 44 and 45 (Kabat numbering) or combinations thereof. Antibodies of the invention possess increased affinity and improved aggregation stability. 124-. (canceled)25. A method for treatment of an IL-17A-mediated disease or disorder , comprising administering to a patient in need thereof a therapeutically effective amount of an antibody or a fragment thereof that specifically binds to human IL-17A comprising a heavy chain variable domain V , and a light chain variable domain Vcomprising the amino acid sequence of SEQ ID NO: 8 , wherein the Vcomprises:a) HCDR1, HCDR2 and HCDR3 comprising the amino acid sequences of SEQ ID NO: 4, SEQ ID NO: 5 and SEQ ID NO: 6, respectively; or [{'sup': 'th', 'the amino acid at the 6position of SEQ ID.
