Restraints

High Development and Manufacturing Costs

The complex processes involved with the development of ADCs such as conjugating an antibody, finding a suitable linker, and a cytotoxic payload, requires specific raw materials and specialized manufacturing facilities with highly skilled professionals. This complexity of ADC manufacturing processes requires heavy investments which can potentially delay the development and commercialization timelines, further limiting market entry for smaller biotech companies. Additionally, the high attrition rates in clinical trials due to the lengthy and complex nature of developing an ADC, can lead to significant financial losses for the companies and delay the time-to-market for potential new therapies.

Opportunities

Progress in ADC Technology and Expanding Applications

The ongoing advancements in ADC technologies with focus on improving conjugation strategies and the synthesis of more effective cytotoxic agents, leading to development of more potent and safer ADCs. Improvements in linker technology used for connecting the antibody and the cytotoxic payload are enhancing the stability of ADCs in bloodstream, further enabling targeted drug release at the tumor site with improved efficiency and decreased toxicity. Development of techniques such as site-specific conjugation allowing precise attachment of the payload to the antibody are leading more reliable ADCs with controlled drug-to-antibody ratios (DAR). ‘

Additionally, the proven efficacy of ADCs for providing targeted and effective treatments for several cancers as well as expanding applications of ADCs beyond oncology in other therapeutic areas such as autoimmune disorders and infectious diseases are creating new opportunities for market growth.
