Benchmarking emerging chromatographic platforms for mRNA-LNP characterization and scalable process enablement

Abstract

Lipid nanoparticles (LNPs) are now the leading delivery platform for nucleic acid therapeutics, supporting applications from prophylactic mRNA vaccines to in vivo gene editing, in vivo CAR-T, protein replacement, and personalized cancer immunotherapy. As formulations incorporate novel ionizable lipids, targeting ligands, and multi-component payloads, analytical complexity increases, and no single method can capture all critical quality attributes (CQAs). This study benchmarks the PATfix LNP Switcher Platform against established (RiboGreen, DLS) and emerging (FFF-UV-MALS-DLS-RI) techniques. The 2D LNP Switcher uses independent flow paths, dual UV-Vis/MALS detection, and automated switching between non-disruptive and denaturing modes, enabling preparation-free analysis of intact particles followed by online disruption to quantify encapsulated nucleic acid, free mRNA, and lipid–mRNA adducts. This platform supports integrated, multi-parameter LNP characterization that aligns process development, manufacturing, and evolving regulatory expectations, and complements the scalable, preparative purification of mRNA-LNPs on CIMmultus OH monoliths.

A Preliminary Roadmap for Empirical Research on Agile Software Development

Some claim that especially in the field of agile software development the research lags years behind of the practice. In this paper, we characterize the status and main challenges for research on agile software development, and propose a preliminary roadmap, focusing on providing more empirical research, primarily on experienced agile teams and organizations, connecting better to existing streams of research in more established fields, giving more attention to management-oriented approaches, and finally give more emphasis to the core ideas in agile software development in order to increase our understanding. We hope that this preliminary roadmap serves as a starting point for creating a common research agenda and enables the generation of fruitful discussions and research results from the field.

Scrum in a Multiproject Environment: An Ethnographically-Inspired Case Study on the Adoption Challenges

Agile methods continue to gain popularity. In particular, the Scrum method appears to be on the verge of becoming a de-facto standard in the industry, leading the so called Agile movement. While there are success stories and recommendations, there is little scientifically valid evidence of the challenges in the adoption of Agile methods in general, and Scrum in particular. Little, if anything, is empirically known about the application and adoption of Scrum in a multi-team and multi-project situation. The authors carried out an ethnographically informed longitudinal case study in industrial settings and closely followed how the Scrum method was adopted in a 20-person department, working in a simultaneous multi-project R&D environment. Altogether 10 challenges pertinent to the case of multi-team multi-project Scrum adoption were identified in the study. The authors contend that these results carry great relevance for other industrial teams. Future research avenues arising from the study are indicated.
