With fourteen approved drugs and several drug candidates being evaluated under different stages of development, antibody drug conjugates (ADCs) are now recognized as a potent class of targeted therapeutics. The success of this relatively novel class of therapeutics is attributed to the ability of lead molecules to specifically identify and eliminate disease associated cells / pathogens, consequently, addressing most of the concerns related to off target toxicities. In this context, the role of the linker molecule and the conjugation technology used is pivotal. In fact, conjugation chemistry has been shown to be directly related to the drug to antibody ratio (DAR) achieved, and thereby, governs the pharmacokinetic and pharmacodynamic properties of an ADC. Over time, a variety of other conjugated therapeutics have also been developed and are under evaluation. Conventional conjugation technologies used for the development of ADCs exploited the superficial lysine residues that were inherent to the native antibody structure, or the inter-chain cysteine residues, for drug-linker attachment. Over time, the evolution of recombinant DNA technology and advances in conjugation techniques, have enabled researchers to significantly improve the bioconjugation process. In fact, next generation conjugation technologies use artificially integrated lysine / cysteine residues in order to improve the DAR of the resulting conjugate. Additionally, there are multiple technologies that claim to offer site-specific conjugation. There are a number of other noteworthy developments in the conjugation technologies domain, which include a variety of competent platforms based on various ligation, disulfide bridging and protein remodelling approaches. Currently, several ADC drug developers are relying on the ADC linker and conjugation technology providers for the development of novel ADC targets intended to treat various oncological indications. Driven by the growing demand for antibody drug conjugates, the ADC linker and conjugation technologies market is anticipated to witness substantial growth in the foreseen future.

Assessing the Growth Opportunities in the ADC Linker and Conjugation Technologies Market
The evolutionary advances in conjugation and linker technologies have enabled the development of viable treatment options. Such improvements have significantly altered the therapeutic potential and likely applications of ADCs. In other words, succeeding generations of conjugated drugs, based on improved technologies are more selective in targeting diseased cells and have broader therapeutic windows. Despite the current opinion on the superiority of this class of therapeutics, the existing understanding of the biochemical, immunological, pharmacological, and molecular aspects of ADCs needs to be furthered to design and develop better versions of these products. The choice of a suitable target antigen and cytotoxic payload is important, however, the conjugation approach used, and linker chemistry involved, are equally crucial elements for manufacturing viable leads. As a result, there are a number of efforts directed towards the development of better and site-specific conjugation methods that enable manufacturers to synthesize homogeneous batches of ADCs.
