Abstract
Antibody-drug conjugates (ADCs) are designed by chemically linking highly potent cytotoxic small molecule drugs to monoclonal antibodies of unique specificity for targeted destruction of cancer cells. This innovative class of molecules incurs unique developmental challenges due to its structural complexity of having both small molecule and protein components. The stability of the small molecule payload on the ADC is a critical attribute as it directly relates to product efficacy and patient safety. This study describes the use of an end-to-end automated workflow for effective and robust characterization of the small molecule drug while it is conjugated to the antibody. In this approach, online deconjugation was accomplished by an autosampler user defined program and 1D size exclusion chromatography was utilized to provide separation between small molecule and protein species. The small molecule portion was then trapped and sent to the 2D for separation and quantification by reversed-phase liquid chromatography with identification of impurities and degradants by mass spectrometry. The feasibility of this system was demonstrated on an ADC with a disulfide-based linker. This fully automated approach avoids tedious sample preparation that may lead to sample loss and large assay variability. Under optimized conditions, the method was shown to have excellent specificity, sensitivity (LOD of 0.036 µg/mL and LOQ of 0.144 µg/mL), linearity (0.04-72.1 µg/mL), precision (system precision %RSD of 1.7 and method precision %RSD of 3.4), accuracy (97.4 % recovery), stability-indicating nature, and was successfully exploited to analyze the small molecule drug on a panel of stressed ADC samples. Overall, the workflow established here offers a powerful analytical tool for profiling the in-situ properties of small molecule drugs conjugated to antibodies and the obtained information could be of great significance for guiding process/formulation development and understanding pharmacokinetic/pharmacodynamic behavior of ADCs.

Abstract
Residual free-drug-related species that are present in antibody-drug conjugates (ADC) are a potential safety risk to patients and are therefore categorized as a critical quality attribute that must be strictly monitored and controlled. Among the many analytical methods developed for free-drug analysis, reversed-phase liquid chromatography (RP-LC) is the most common approach. Conventional RP-LC methods for free-drug analysis, however, involve labor-intensive sample preparation. Here we present a new RP-LC method to directly analyze free-drug-related species in an ADC sample without the need for sample preparation. In our work, free-drug-related species were very well separated from ADC peaks in the chromatography gradient. Typical performance issues observed in conventional RP-LC, such as column fouling, detection interference, and carryover, were not observed or were negligible with this new method. Three options were evaluated for free-drug quantitation: Strohl (2017) [1] use of an external free drug calibration curve for determination of absolute concentration; Perez et al. (2014) [2] calculation of relative percentage based on peak area ratio between free drug and ADC at a characteristic wavelength unique for drug payload; and (Beck et al., 2017) [3] calculation of relative percentage based on peak area ratio between free drug and corrected ADC peak area (at any wavelength). The method with calibration curve provides the highest sensitivity, the best accuracy and precision for determination of free drug present in the ADC. However, the second and third options were simpler because they eliminated the need for an external calibration curve, making them worth exploring. Due to its simplicity and compatibility with mass spectrometry, the new method is also a good choice for direct analysis of stability samples.

Abstract
Modern size exclusion chromatography (SEC) can be defined by the use of relatively small columns (e.g., 150 × 4.6 mm) packed with sub-3 μm particles, allowing a 3- to 5-fold increase in method throughput compared to that of conventional SEC. The quick success of the first sub-2 μm SEC column introduced in 2010 led to the development of numerous ultra-high performance (UHP)-SEC columns for the analysis of therapeutic monoclonal antibody (mAb)-based products. Aggregates also known as high-molecular-weight species (HMWS) are indeed one of the most important critical quality attributes (CQAs) of mAbs, as HMWS may decrease the product efficacy or cause immunogenicity effects. Therefore, the confident characterization of mAbs requires strong knowledge of not only modern SEC performance (i.e., selectivity and efficiency) but also the inherent limitations caused by non-specific interactions more likely to occur with complex antibody drug conjugates (ADCs) and some commercial mAb products. This review discusses the importance of liquid chromatographic (LC) instrumentation in order to exploit the full potential of modern SEC columns and current trends to hyphenate SEC to mass spectrometry (MS). Recent applications for antibody-based products (i.e., mAbs, ADCs, Fc-Fusion proteins and bispecific antibodies) are presented. Finally, tips and tricks are provided to further optimize SEC separations and maintaining their performance over time with better understanding of unexpected SEC results.

Abstract
Antibody-drug conjugates (ADCs) are a growing class of biotherapeutics in which a potent small molecule is linked to an antibody. ADCs are highly complex and structurally heterogeneous, typically containing numerous product-related species. One of the most impactful steps in ADC development is the identification of critical quality attributes to determine product characteristics that may affect safety and efficacy. However, due to the additional complexity of ADCs relative to the parent antibodies, establishing a solid understanding of the major quality attributes and determining their criticality are a major undertaking in ADC development. Here, we review the development challenges, especially for reliable detection of quality attributes, citing literature and new data from our laboratories, highlight recent improvements in major analytical techniques for ADC characterization and control, and discuss newer techniques, such as two-dimensional liquid chromatography, that have potential to be included in analytical control strategies.

Abstract
Antibody Drug Conjugates (ADCs) are innovative biopharmaceuticals gaining increasing attention over the last two decades. The concept of ADCs lead to new therapy approaches in numerous oncological indications as well in infectious diseases. Currently, around 60 CECs are in clinical trials indicating the expanding importance of this class of protein therapeutics. ADCs show unprecedented intrinsic heterogeneity and address new quality attributes which have to be assessed. Liquid chromatography is one of the most frequently used analytical method for the characterization of ADCs. This review summarizes recent results in the chromatographic characterization of ADCs and supposed to provide a general overview on the possibilities and limitations of current approaches for the evaluation of drug load distribution, determination of average drug to antibody ratio (DARav), and for the analysis of process/storage related impurities. Hydrophobic interaction chromatography (HIC), reversed phase liquid chromatography (RPLC), size exclusion chromatography (SEC) and multidimensional separations are discussed focusing on the analysis of marketed ADCs. Fundamentals and aspects of method development are illustrated with applications for each technique. Future perspectives in hydrophilic interaction chromatography (HILIC), HIC, SEC and ion exchange chromatography (IEX) are also discussed.
