To investigate the mechanisms of action underlying the therapeutic effect of CD4 monoclonal antibody therapy in rheumatoid arthritis (RA), clinical responses were compared with several laboratory parameters. Twenty-nine RA patients received either 10 mg, 50 mg or 100 mg of cM-T412, a chimeric CD4 MoAb, for 7 days. The CD4 binding sites on circulating lymphocytes were saturated directly with cM-T412 and serum levels of unbound cM-T412 accumulated towards day 7 of treatment only in the patients treated with 50 and 100 mg. The treatment induced an instant and prolonged depression of the number of circulating CD4+ cells, similar for all dosages. Clinical improvement was observed predominantly in the patients treated with 50 or 100 mg cM-T412 daily and did not correlate with changes in counts of circulating leucocyte subsets nor with changes in serum cytokine levels. An antiglobulin response against cM-T412 developed in a majority of the patients. Side effects on the first day of treatment were correlated with an increase of serum IL-6 levels. This study indicates that a favourable clinical effect of cM-T412 administration was associated with the presence of unbound cM-T412 in the circulation of RA patients. Therefore penetration of unbound cM-T412 into the site of inflammation might determine the therapeutic effect in RA.
