Bioactive materials, e.g. therapeutic agents for treating a condition that afflicts a patient, are delivered to the afflicted organ in a site-specific manner by coupling the bioactive agent to an antibody or fragment or derivative thereof that recognizes a substance unique to that organ. For example, therapeutic agents for treating conditions of the prostate gland such as adenocarcinoma of the prostate, benign prostatic hypertrophy and prostatitis can be delivered to the prostate by coupling the thereapeutic agent to an antibody against a substance secreted by the prostate, e.g. prostatic specific antigen or prostatic acid phosphatase.
