Monospecific antibodies have been utilised increasingly for anti-cancer drug targeting owing to their ability to minimise off-target toxicity by binding specifically to a tumour epitope, hence selectively delivering drugs to the tumour cells. Nevertheless, the monospecific antibodies only engage a single cell surface epitope to deliver their drug payload. Hence, their performance is often unsatisfactory in cancers where multiple epitopes need to be engaged for optimal cellular internalisation. In this context, bispecific antibodies (bsAbs) that simultaneously target two distinct antigens or two distinct epitopes of the same antigen offer a promising alternative in antibodybased drug delivery. This review describes the recent advances in developing bsAb-based drug delivery strategies, encompassing the direct conjugation of drug to bsAbs to form bispecific antibody-drug conjugates (bsADCs) and the surface functionalisation of nanoconstructs with bsAbs to form bsAb-coupled nanoconstructs. The article first details the roles of bsAbs in enhancing the internalisation and intracellular trafficking of bsADCs with subsequent release of chemotherapeutic drugs for an augmented therapeutic efficacy, particularly among heterogeneous tumour cell populations. Then, the article discusses the roles of bsAbs in facilitating the delivery of drug-encapsulating nanoconstructs, including organic/inorganic nanoparticles and large bacteria-derived minicells, that provide a larger drug loading capacity and better stability in blood circulation than bsADCs. The limitations of each type of bsAb-based drug delivery strategy and the future prospects of more versatile strategies (e.g., trispecific antibodies, autonomous drug delivery systems, theranostics) are also elaborated.
