Abstract
Autoimmune diseases vary in the magnitude and diversity of autoantibody profiles, and these differences may be a consequence of different types of breaks in tolerance. Here, we compared the disparate autoimmune diseases autoimmune polyendocrinopathy-candidiasis-ecto-dermal dystrophy (APECED), systemic lupus erythematosus (SLE), and Sjogren's syndrome (SjS) to gain insight into the etiology of breaks in tolerance triggering autoimmunity. APECED was chosen as a prototypical monogenic disease with organ-specific pathology while SjS and SLE represent polygenic autoimmunity with focal or systemic disease. Using protein microarrays for autoantibody profiling, we found that APECED patients develop a focused but highly reactive set of shared mostly anti-cytokine antibodies, while SLE patients develop broad and less expanded autoantibody repertoires against mostly intracellular autoantigens. SjS patients had few autoantibody specificities with the highest shared reactivities observed against Ro-52 and La. RNA-seq B-cell receptor analysis revealed that APECED samples have fewer, but highly expanded, clonotypes compared with SLE samples containing a diverse, but less clonally expanded, B-cell receptor repertoire. Based on these data, we propose a model whereby the presence of autoreactive T-cells in APECED allows T-dependent B-cell responses against autoantigens, while SLE is driven by breaks in peripheral B-cell tolerance and extrafollicular B-cell activation. These results highlight differences in the autoimmunity observed in several monogenic and polygenic disorders and may be generalizable to other autoimmune diseases.

Abstract
In recent years, acceleration of development timelines has become a major focus within the biopharmaceutical industry to bring innovative therapies faster to patients. However, in order to address a high unmet medical need even faster further acceleration potential has to be identified to transform "speed-to-clinic" concepts into "warp-speed" development programs. Recombinant Chinese hamster ovary (CHO) cell lines are the predominant expression system for monoclonal antibodies (mAbs) and are routinely generated by random transgene integration (RTI) of the genetic information into the host cell genome. This process, however, exhibits considerable challenges such as the requirement for a time-consuming clone screening process to identify a suitable clonally derived manufacturing cell line. Hence, RTI represents an error prone and tedious method leading to long development timelines until availability of Good Manufacturing Practice (GMP)-grade drug substance (DS). Transposase-mediated semi-targeted transgene integration (STI) has been recently identified as a promising alternative to RTI as it allows for a more rapid generation of high-performing and stable production cell lines. In this report, we demonstrate how a STI technology was leveraged to develop a very robust DS manufacturing process based on a stable pool cell line at unprecedented pace. Application of the novel strategy resulted in the manufacturing of GMP-grade DS at 2,000 L scale in less than three months paving the way for a start of Phase I clinical trials only six months after transfection. Finally, using a clonally derived production cell line, which was established from the parental stable pool, we were able to successfully implement a process with an increased mAb titer of up to 5 g per liter at the envisioned commercial scale (12,000 L) within eight months.

Abstract
Bispecific antibodies (bsAbs) and antibody-drug conjugates (ADCs) have already demonstrated benefits for the treatment of cancer in several clinical studies, showing improved drug selectivity and efficacy. In particular, simultaneous targeting of prominent cancer antigens, such as EGF receptor (EGFR) and c-MET, by bsAbs has raised increasing interest for potentially circumventing receptor cross-talk and c-MET-mediated acquired resistance during anti-EGFR monotherapy. In this study, we combined the selectivity of EGFR × c-MET bsAbs with the potency of cytotoxic agents via bispecific antibody-toxin conjugation. Affinity-attenuated bispecific EGFR × c-MET antibody-drug conjugates demonstrated high in vitro selectivity toward tumor cells overexpressing both antigens and potent anti-tumor efficacy. Due to basal EGFR expression in the skin, ADCs targeting EGFR in general warrant early safety assessments. Reduction in EGFR affinity led to decreased toxicity in keratinocytes. Thus, the combination of bsAb affinity engineering with the concept of toxin conjugation may be a viable route to improve the safety profile of ADCs targeting ubiquitously expressed antigens.
