Multidrug-resistant Gram-negative bacteria pose an increasing threat to human health, and development of novel antibiotics would be one answer to this challenge. Most efforts to date have focused on development of broad- spectrum antibiotics and unfortunately with limited success in terms of approved new drugs. As an alternative approach we have developed an RNA therapeutics platform based on peptide nucleic acid (PNA) antisense technology that allows rational discovery and development of designer precision, narrow spectrum antibiotics optimized to target different multidrug resistant bacterial species using the same platform and principle. Using this platform, PNA antisense antibiotics (PAAs) showing (sub)micromolar antibacterial activity against Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa (including multidrug resistant clinical isolates) have been discovered. Lead compounds are bactericidal via an antisense mechanism of action, exhibit low frequency of resistance, have exquisite biostability in human (and mouse ) serum, very low toxicity in human cell culture (HepG2), good in vivo tolerability in mice via sc, iv and ip administration. Finally, in vivo efficacy against MDR E. coli and A, baumannii in urinary tract infection, sepsis and soft tissue infection mouse models has been demonstrated. Based on these in vitro as well as in vivo results the prospects of developing novel precision antisense antibiotics against infections by multidrug resistant Gram-negative bacteria will be discussed.

My laboratory is involved in the discovery and development of cyclic peptides for therapeutic applications. In recent years, we have begun to address the long-standing goal of developing target-specific peptides that are membrane-permeable and orally available. To this end, we are focusing on the generation of cyclic peptides that have a relatively small size (< 800 Da) and a limited polar surface area, so that they have a high chance of passively crossing membranes. To generate sub-kilodalton cyclic peptides that bind to disease targets of interest, we have established an approach based on nanomole-scale cyclic peptide synthesis and high-throughput screening of crude products (1, 2). In short, we generate thousands of peptides by solid-phase peptide synthesis and combinatorially diversify them by reacting them with a myriad of chemical building blocks. In this approach, all reagents are transferred in nanolitre volumes by acoustic dispensing and reactions are performed at the nanomole scale, allowing tens of thousands of cyclic peptides to be synthesised and screened in a short time. Recently, we have shown that cyclic peptides developed using this approach can achieve good oral availability (3). In my talk, I will explain the approach to the synthesis and screening of cyclic peptide libraries, show examples of libraries and their screening, present nanomolar ligands we have developed against different proteins, including a protein-protein interaction target, and show data on the membrane permeability and oral availability of the peptides.

Membrane receptor proteins are essential in cellular signaling. In recent years, there has been a surge of interest in discovering peptide binders to membrane receptors due to their potential use for diagnostic, therapeutic, and theranostic purposes. Phage display technology is frequently employed to identify peptide binders to recombinant proteins. Improper folding of recombinant proteins, a well-known challenge, would hinder the identification of peptide binders. In our lab, we developed a cell-based model to overexpress membrane proteins for phage display biopanning to ensure reliable identification of cyclic peptide binders. In this presentation, we show different examples of novel CLIPSTM peptides with excellent binding affinities and selectivities to the protein of interest that were identified using our novel cell-based model. We illustrate the techniques that enable cell-based biopannings using a benchmark membrane protein. Additionally, we will share preliminary data on a “real” difficult-to-target protein for which a recombinant alternative is currently unavailable. The work presented convincingly illustrates that cell-based biopanning is a reliable model for discovering peptide binders to membrane-bound proteins that are difficult to target using the recombinant form of that same protein.

In this presentation learn how LCMS together with new software solutions is used to easily identify impurities, improve the characterization of oligonucleotides and by the application of a new fragmentation technique is increasing the sequence coverage of oligonucleotides. As targets move to larger oligonucleotides and the thousands of bases of mRNA capillary electrophoresis (CE) is helping to profile impurities. In this presentation we will discuss how chemical kits together with CE are enabling scientists to detect size impurities from gRNA and the prime editing guide RNA used for CRIPSR to the mRNA found in lipid nanoparticles. Finally discover how CE is applied to measuring genome titre and together with viral protein detection can be used to calculate the empty / full ration of viral particles used in cell and gene therapy products.

Improving understanding of processes offers dual benefits for oligonucleotide development. Firstly, it establishes a potential platform for creating similar molecules with different sequences, thereby accelerating process development time /efforts. Secondly, it ensures robust processes that yield high-quality APIs. While Quality by Design (QbD) is often equated with Design of Experiments (DoE), it actually encompasses overall process design, with DoE being just one aspect. We'll explore how embracing QbD principles can optimize process understanding and utilization of data, including examples of how mathematical modeling systematically gathers data, enhances process understanding , and contributes to process characterization in solid-supported synthesis.
While alternative methods are being explored, solid-supported synthesis remains the most established and practical approach for producing oligonucleotides, especially in smaller quantities. Before 2016, the main focus was on introducing oligonucleotides as therapeutics. However, with over 15 approvals in an 8-year period, and considering the potential for a platform approach, developing a strategy for process characterization would greatly benefit the overall oligonucleotide portfolio and streamline the filing process with a deeper understanding. This study emphasizes the importance of the Quality by Design (QbD) concept from development through to product lifecycle. Using case studies to model specific unit operations like TFF, we demonstrate how this approach can provide regulatory benefits.
Recent RNA approvals highlight the need for robust analytical methods to monitor critical quality attributes (CQAs), ensuring control of manufacturing processes and product quality. Oligonucleotide mapping via liquid chromatography / mass spectrometry is effective for CQA assessment, however, sample preparation approaches and data handling present a time-consuming challenge. A novel digestion procedure, data acquisition and data processing workflow was developed to produce fragment assignments for sgRNA and mRNA, including measurement of key CQAs

RNA editing technologies have the potential to become a new class of innovative medicines with applicability to a broad range of therapeutic areas. Two technologies (Axiomer and Trident) currently in development use editing oligonucleotides to mediate single nucleotide changes at the RNA level in a highly specific and targeted way using endogenous molecular machinery. Axiomer uses Adenosine Deaminase acting on RNA, or ADAR, and Trident uses pseudouridine synthase, which are naturally present in human cells. This presentation will report insights into structure-activity relationship (SAR) and delivery optimization for these technologies. Additionally, pioneering activities to unfold new opportunities in the field, including the development of reliable in vitro and in vivo models (including non-human primates), and efforts to maximize translatability for the development of new medicines addressing unmet medical needs will be presented.
