BioDesign: Accelerating the Momentum of Bioconjugate Therapeutics

"BioDesign explores innovative strategies to enhance the efficacy and application of bioconjugate therapeutics, aiming to expedite their development and deployment. This multidisciplinary approach combines biology, chemistry, and engineering to propel advancements in drug delivery, targeting, and efficacy, potentially revolutionizing medical treatment modalities."

Over the last several decades, mounting interest has positioned bioconjugate therapeutics as one of the most promising biopharmaceutical modalities. Work in chemical biology, including novel conjugation technologies and linker architectures, has set the stage for success in bioconjugate development. While bioconjugates encompass a variety of therapeutic subclasses, antibody-drug conjugates (ADCs) have emerged as the primary player in the field. Eleven ADCs are currently approved by the U.S. Food & Drug Administration (FDA) and more than 200 clinical trials are underway, according to ClinicalTrials.gov.

Despite the considerable progress made in antibody targets and payloads, continued innovation will be necessary to navigate the complexities of this modality and help the field reach its full potential. For example, advances in linker technologies have improved the performance of previously identified antibody-payload combinations, making linker design a strong area of focus for advancing ADCs further. However, early-stage biopharma companies typically lack access to the specialized resources and knowledge needed to design and execute a bioconjugation strategy that meets their desired parameters, let alone the necessary infrastructure to manufacture linkers at scale. Outsourcing these capabilities allows developers to focus their resources on target development and ADC optimization. Experienced, well-equipped partners will be instrumental in bringing the next wave of bioconjugate drugs to the clinic.

Facilitating Progress with Specialized Bioconjugation Expertise

Bioconjugate drugs are more than the sum of their components, a targeting molecule and a payload joined by a linker. The linker itself is, in fact, a key variable in tuning and optimizing ADC performance. Linker design plays a vital role in the stability of an ADC, ensuring the therapeutic payload remains tethered and effectively reaches its target, which prevents toxicity and off-target effects. Linkers also have important implications for ADC solubility, minimizing the impact of hydrophobic payloads and preventing off-target accumulation. Finally, linkers must be reliably and scalably manufactured to specific purity requirements to ensure the structural and functional homogeneity of ADCs. Optimal linker design balances these parameters to maximize desirable features without disrupting others.

While a new appreciation for the importance of linker design has encouraged the development of more sophisticated and complex structures, executing a successful bioconjugation strategy for ADC development requires deep knowledge of chemical biology, synthetic chemistry, and specialized manufacturing capabilities. Drug developers require manufacturing partners who can offer precision linker design and customization capabilities, as well as the expertise and capacity needed to ensure consistent, high-purity linker production.
