Abstract
A composition for treating a subject is provided. The composition includes antigen specific dimeric secretory IgA and pentameric IgM therapeutic. A process for manufacturing a medicament for the treatment of C. difficile associated disease in a human is also provided that the modification of antigen specific dimeric secretory IgA and pentameric IgM with secretory component to form a antigen specific dimeric secretory IgA and pentameric secretory IgM therapeutic. The antigen specific dimeric secretory IgA and the pentameric secretory IgM therapeutic is then mixed with formulating agents to create a capsule, tablet, liquid or suppository dosing form. The therapeutic is amenable to enrobement directly through microencapsulation or the dosing form is coated with an enteric coating. A method of C. difficile treatment with the therapeutic is also provided that is amenable to supplementation with concurrent or prior antibiotic administration.
