Abstract RU 2401277 C2

FIELD: chemistry.

SUBSTANCE: invention relates to anti-M-CSF-specific antibodies based on RX1 or originating from RX1, and which more than 785% compete with monoclonal antibodies RX1, MC1 and/or MC3 for bonding with M-CSF (macrophagal colony-stimulating factor). The non-mouse antibody is two-stranded, contains a certain amino acid sequence (given in the formula of invention and list of sequences) and retains high affinity towards M-CSF. The invention discloses an isolated nucleic acid which codes the said antibody, an expression vector, a host cell and a method of producing the anti-M-CSF-antibody using a host cell or hybridome, particularly ATCC PTA-6263 or ATCC PTA-6264 hybridome. The invention describes a pharmaceutical composition containing said antibodies, sets containing pharmaceutical compositions and methods of preventing and treating osteoporosis in a person suffering from an osteolytic disease.

EFFECT: disclosed antibodies can inhibit osteoclast differentiation, which facilitates their use as highly effective preparations for treating osteolysis, cancer with metastases and osteoporosis associated with cancer metastases.
