The forfeiture of the proceeds of drug-related offences does not seem to have received much attention as yet from British Commonwealth countries. Whereas in some of these countries specific legislation exists in relation to forfeiture, in many other countries the act of forfeiture falls within the purview of general criminal law. Forfeiture presupposes enquiry and search, two procedures which involve integral aspects of present-day human rights law, and which seem to be impeded at almost every stage of the process concluding in forfeiture. Time and the procedure for execution of judgments seem to be two significant factors in the successful enforcement of forfeiture judgments. Unfortunately, given the present practice of maintaining inviolability of bank secrecy, effective enforcement of forfeiture judgments is not possible. Perhaps an international convention may offer some assistance in the successful implementation of a forfeiture judgment, especially where the ill-gotten gains have been transferred to a foreign jurisdiction.
Certain anti-idiotypic antibodies that bind to the antigen-combining sites of antibodies can effectively mimic the three-dimensional structures and functions of the external antigens and can be used as surrogate antigens for active specific immunotherapy. Extensive studies in animal models have demonstrated the efficacy of these vaccines for triggering the immune system to induce specific and protective immunity against bacterial, viral and parasitic infections as well as tumors. Several monoclonal anti-idiotype antibodies that mimic distinct human tumor-associated antigens have been developed and characterized. Encouraging results have been obtained in recent clinical trials using these anti-idiotype antibodies as vaccines. In this article, we will review the current literature and discuss the potential of this novel therapeutic approach for various human cancers.
Immunization with anti-idiotype (Id) antibodies represents a novel new approach to active immunotherapy. Extensive studies in animal tumor models have demonstrated the efficacy of anti-Id vaccines in preventing tumor growth and curing mice with established tumor. We have developed and characterized several murine monoclonal anti-Id antibodies (Ab2) which mimic distinct human tumor-associated antigens (TAA) and can be used as surrogate antigens for triggering active anti-tumor immunity in cancer patients. Encouraging results have been obtained in recent clinical trials. In this article, we will review the existing literature and summarize our own findings showing the potential of this approach for various human cancers. We will also discuss where anti-Id vaccines may perform better than traditional antigen vaccines.
Anti-idiotype (Id) vaccine therapy has been tested and shown to be effective, in several animal models, for triggering the immune system to induce specific and protective immunity against bacterial, viral and parasitic infections. The administration of anti-Id antibodies as surrogate tumor-associated antigens (TAA) also represents another potential application of the concept of the Id network. Limited experience in human trials using anti-Id to stimulate immunity against tumors has shown promising results. In this "counter-point" article, we discuss our own findings showing the potential of anti-Id antibody vaccines to be novel therapeutic approaches to various human cancers and also discuss where anti-Id vaccines may perform better than traditional multiple-epitope antigen vaccines.
