In Vivo Metabolite Profiles of an N-Acetylgalactosamine-Conjugated Antisense Oligonucleotide AZD8233 Using Liquid Chromatography High-Resolution Mass Spectrometry: A Cross-Species Comparison in Animals and Humans. Drug Metab Dispos 2023; 51:1350-1361. [PMID: 37429729 DOI: 10.1124/dmd.123.001370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 07/12/2023] Open
Abstract
AZD8233, a liver-targeting antisense oligonucleotide (ASO), inhibits subtilisin/kexin type 9 protein synthesis. It is a phosphorothioated 3-10-3 gapmer with a central DNA sequence flanked by constrained 2'-O-ethyl 2',4'-bridged nucleic acid (cEt-BNA) wings and conjugated to a triantennary N-acetylgalactosamine (GalNAc) ligand at the 5'-end. Herein we report the biotransformation of AZD8233, as given by liver, kidney, plasma and urine samples, after repeated subcutaneous administration to humans, mice, rats, rabbits, and monkeys. Metabolite profiles were characterized using liquid chromatography high-resolution mass spectrometry. Metabolite formation was consistent across species, mainly comprising hydrolysis of GalNAc sugars, phosphodiester-linker hydrolysis releasing the full-length ASO, and endonuclease-mediated hydrolysis within the central DNA gap followed by exonuclease-mediated 5'- or 3'-degradation. All metabolites contained the 5'- or 3'-cEt-BNA terminus. Most shortmer metabolites had the free terminal alcohol at 5'- and 3'-positions of ribose, although six were found retaining the terminal 5'-phosphorothioate group. GalNAc conjugated shortmer metabolites were also observed in urine. Synthesized metabolite standards were applied for (semi)quantitative metabolite assessment. Intact AZD8233 was the major component in plasma, whereas the unconjugated full-length ASO was predominant in tissues. In plasma, most metabolites were shortmers retaining the 3'-cEt-BNA terminus, whereas metabolites containing the 5'- or 3'-cEt-BNA terminus were detected in both tissues and urine. All metabolites in human plasma were also detected in all nonclinical species, and all human urine metabolites were detected in monkey urine. In general, metabolite profiles in animal species were qualitatively similar and quantitatively exceeded the exposures of the circulating metabolites in humans at the doses studied. SIGNIFICANCE STATEMENT: This study presents metabolite identification and profiling of AZD8233, an N-acetylgalactosamine-conjugated antisense oligonucleotide (ASO), across species. A biotransformation strategy for ASOs was established by utilizing biologic samples collected from toxicology and/or clinical studies and liquid chromatography high-resolution mass spectrometry analysis without conducting bespoke radiolabeled absorption, distribution, metabolism, and excretion studies. The generated biotransformation package was considered adequate by health authorities to progress AZD8233 into a phase 3 program, proving its applicability to future metabolism studies of ASOs in drug development.

Assessment of immunostimulatory responses to the antimiR-22 oligonucleotide compound RES-010 in human peripheral blood mononuclear cells. Front Pharmacol 2023; 14:1125654.

Abstract
microRNA-22 (miR-22) is a key regulator of lipid and energy homeostasis and represents a promising therapeutic target for NAFLD and obesity. We have previously identified a locked nucleic acid (LNA)-modified antisense oligonucleotide compound complementary to miR-22, designated as RES-010 that mediated robust inhibition of miR-22 function in cultured cells and in vivo. In this study we investigated the immune potential of RES-010 in human peripheral blood mononuclear cells (PBMCs). We treated fresh human peripheral blood mononuclear cells isolated from six healthy volunteers with different concentrations of the RES-010 compound and assessed its proinflammatory effects by quantifying IL-1β, IL-6, IFN-γ, TNF-α, IFN-α2a, IFN-β, IL-10, and IL-17A in the supernatants collected 24 h of treatment with RES-010. The T-cell activation markers, CD69, HLA-DR, and CD25 were evaluated by flow cytometry after 24 and 144 h of treatment, respectively, whereas cell viability was assessed after 24 h of treatment with RES-010. Our results show that RES-010 compound does not induce any significant immunostimulatory responses in human PBMCs in vitro compared to controls, implying that the proinflammatory potential of RES-010 is low.

Int J Mol Sci 2022; 23:13359. [PMID: 36362145 PMCID: PMC9657934 DOI: 10.3390/ijms232113359] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/20/2022] [Accepted: 10/25/2022] [Indexed: 08/01/2023] Open
Abstract
Myotonic dystrophy type 1 (DM1) is a dominant genetic disease in which the expansion of long CTG trinucleotides in the 3' UTR of the myotonic dystrophy protein kinase (DMPK) gene results in toxic RNA gain-of-function and gene mis-splicing affecting mainly the muscles, the heart, and the brain. The CUG-expanded transcripts are a suitable target for the development of antisense oligonucleotide (ASO) therapies. Various chemical modifications of the sugar-phosphate backbone have been reported to significantly enhance the affinity of ASOs for RNA and their resistance to nucleases, making it possible to reverse DM1-like symptoms following systemic administration in different transgenic mouse models. However, specific tissue delivery remains to be improved to achieve significant clinical outcomes in humans. Several strategies, including ASO conjugation to cell-penetrating peptides, fatty acids, or monoclonal antibodies, have recently been shown to improve potency in muscle and cardiac tissues in mice. Moreover, intrathecal administration of ASOs may be an advantageous complementary administration route to bypass the blood-brain barrier and correct defects of the central nervous system in DM1. This review describes the evolution of the chemical design of antisense oligonucleotides targeting CUG-expanded mRNAs and how recent advances in the field may be game-changing by forwarding laboratory findings into clinical research and treatments for DM1 and other microsatellite diseases.

Abstract
Safety issues caused by pharmaceuticals have frequently occurred worldwide, posing a tremendous threat to human health. As an essential part of drug development, the toxicological analysis and safety evaluation is of great significance. In addition, the risk of pharmaceuticals accumulation in the environment and the monitoring of the toxicity from natural medicines have also received ongoing concerns. Due to a lack of spatial distribution information provided by common analytical methods, analyses that provide spatial dimensions could serve as complementary safety evaluation methods for better prediction and evaluation of drug toxicity. With advances in technical solutions and software algorithms, mass spectrometry imaging (MSI) has received increasing attention as a popular analytical tool that enables the simultaneous implementation of qualitative, quantitative, and localization without complex sample pretreatment and labeling steps. In recent years, MSI has become more attractive, powerful, and sensitive and has been applied in several scientific fields that can meet the safety assessment requirements. This review aims to cover a detailed summary of the various MSI technologies utilized in the biomedical and pharmaceutical area, including technical principles, advantages, current status, and future trends. Representative applications and developments in the safety-related issues of different pharmaceuticals and natural medicines are also described to provide a reference for pharmaceutical research, improve rational clinical medicine use, and ensure public safety.

Abstract
Drug-induced kidney injury has historically been associated with renal tubule injury related to small molecule pharmaceuticals such as nonsteroidal anti-inflammatory drugs, antineoplastic agents, or antibiotics, but as a greater number of alternative classes of medicines such as biotherapeutics, molecular-targeted antineoplastic drugs, chimeric antigen receptor T-cell therapies, antibody-drug conjugates, oligonucleotide therapies, or other immunomodulatory drugs come to market, the presentation of drug-induced nephrotoxicity is changing. This review article describes the potential rare clinical events in drug-induced kidney injury that might be noted with these new therapies and their potential impact on patients. Potential pathogenic mechanisms related to immunogenicity, immune complex formation, and stimulation of downstream proinflammatory pathways with some of these alternative medicine classes have resulted in the potential for glomerulonephritis, acute interstitial nephritis, renal vasculitis, and other immune-mediated renal disorders in humans. This contrasts with nonclinical toxicity studies, where biologic therapies more often result in vasculitis and glomerulonephritis associated with antidrug antibodies and immunomodulatory pharmacology, and which are not always predictive of clinical effects. While nonclinical antidrug antibody-related renal disease is generally not clinically relevant, other immune-mediated nephrotoxicities associated with immunomodulatory drugs may be predictive of clinical adverse events. Fortunately, these conditions are still rare and account for a small percentage of serious adverse events in kidneys of patients.

Abstract
The success of the messenger RNA-based COVID-19 vaccines of Moderna and Pfizer/BioNTech marks the beginning of a new chapter in modern medicine. However, the rapid rise of mRNA therapeutics has resulted in a regulatory framework that is somewhat lagging. The current guidelines either do not apply, do not mention RNA therapeutics, or do not have widely accepted definitions. This review describes the guidelines for preclinical biodistribution studies of mRNA/siRNA therapeutics and highlights the relevant differences for mRNA vaccines. We also discuss the role of in vivo RNA imaging techniques and other assays to fulfill and/or complement the regulatory requirements. Specifically, quantitative whole-body autoradiography, microautoradiography, mass spectrometry-based assays, hybridization techniques (FISH, bDNA), PCR-based methods, in vivo fluorescence imaging, and in vivo bioluminescence imaging, are discussed. We conclude that this new and rapidly evolving class of medicines demands a multi-layered approach to fully understand its biodistribution and in vivo characteristics.

Safety Testing of an Antisense Oligonucleotide Intended for Pediatric Indications in the Juvenile Göttingen Minipig, including an Evaluation of the Ontogeny of Key Nucleases. Pharmaceutics 2021; 13:1442. [PMID: 34575518 PMCID: PMC8470776 DOI: 10.3390/pharmaceutics13091442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/06/2021] [Accepted: 09/07/2021] [Indexed: 11/16/2022] Open
Abstract
The adult Göttingen Minipig is an acknowledged model for safety assessment of antisense oligonucleotide (ASO) drugs developed for adult indications. To assess whether the juvenile Göttingen Minipig is also a suitable nonclinical model for pediatric safety assessment of ASOs, we performed an 8-week repeat-dose toxicity study in different age groups of minipigs ranging from 1 to 50 days of age. The animals received a weekly dose of a phosphorothioated locked-nucleic-acid-based ASO that was assessed previously for toxicity in adult minipigs. The endpoints included toxicokinetic parameters, in-life monitoring, clinical pathology, and histopathology. Additionally, the ontogeny of key nucleases involved in ASO metabolism and pharmacologic activity was investigated using quantitative polymerase chain reaction and nuclease activity assays. Similar clinical chemistry and toxicity findings were observed; however, differences in plasma and tissue exposures as well as pharmacologic activity were seen in the juvenile minipigs when compared with the adult data. The ontogeny study revealed a differential nuclease expression and activity, which could affect the metabolic pathway and pharmacologic effect of ASOs in different tissues and age groups. These data indicate that the juvenile Göttingen Minipig is a promising nonclinical model for safety assessment of ASOs intended to treat disease in the human pediatric population.
