Abstract: The present invention is directed to a method of treating a cytokine-mediated immune reaction in a patient in need of such treatment by administration of an effective amount of anti-cytokine F(ab?)2 antibody fragments. The antibody fragments are preferably free from albumin and of whole antibodies, as well as substantially free of pyrogens. The anti-cytokine F(ab?)2 antibody fragments may be administered with an effective amount of a pharmaceutically acceptable carrier.

Abstract: The present invention is directed to a pharmaceutical composition comprising F(ab′)2 antibody fragments that are preferably free from albumin and of whole antibodies and also substantially free of pyrogens, and an effective amount of a pharmaceutically acceptable carrier. It is also directed to a method for the production of a pharmaceutical composition comprising F(ab′)2 antibody fragments using serum or blood plasma of a mammal that has been previously immunized, as a source of antibodies. The serum or blood plasma is digested with pepsin, followed by separation and purification until the pharmaceutical composition of F(ab′)2 fragments is free of albumin and complete antibodies, and substantially free of pyrogens.

Abstract: The present invention is directed to a pharmaceutical composition comprising F(ab)2 antibody fragments that are preferably free from albumin and of whole antibodies and also substantially free of pyrogens, and an effective amount of a pharmaceutically acceptable carrier. It is also directed to a method for the production of pharmaceutical composition comprising (F(ab)2 antibody fragments using serum or blood plasma of a mammal that has been previously immunized, as a source of antibodies. The serum or blood plasma is digested with an enzyme pepsin, followed by separation and purification until the pharmaceutical composition of F(ab)2 fragments is free of albumin and complete antibodies, and substantially free of pyrogens.
