The present invention provides a novel pharmaceutical composition containing an anti-Fas antibody which is useful as an agent for prophylaxis and/or treatment of an autoimmune disease or rheumatoid arthritis. More particularly, the present invention provides a pharmaceutical composition containing an anti-human Fas antibody having apoptosis inducing activity and a compound having a folate antagonist activity or a dihydrofolate reductase inhibiting activity, as active ingredients. According to the present invention, the amount of the anti-Fas antibody to be used can be reduced in an agent for prophylaxis and/or treatment of an autoimmune disease or rheumatoid arthritis, and thereby, the possibility that the patient becomes tolerant to anti-Fas antibody as a result of the production of antibodies against the anti-Fas antibody in the patient's body or the like can be decreased, and thus there can be provided a pharmaceutical composition of the present invention useful as an excellent agent for prophylaxis and/or treatment which can be used for a long time. |
