Safety and Tolerability of GalNAc-Conjugated Antisense Drugs Compared to the Same-Sequence 2'--Methoxyethyl-Modified Antisense Drugs: Results from an Integrated Assessment of Phase 1 Clinical Trial Data.

The triantennary -acetylgalactosamine (GalNAc) cluster has demonstrated the utility of receptor-mediated uptake of ligand-conjugated antisense drugs targeting RNA expressed by hepatocytes. GalNAc-conjugated 2'--methoxyethyl (2'MOE) modified antisense oligonucleotides (ASOs) have demonstrated a higher potency than the unconjugated form to support lower doses for an equivalent pharmacological effect. We utilized the Ionis integrated safety database to compare four GalNAc-conjugated and four same-sequence unconjugated 2'MOE ASOs.

Investigating mobility and pastoralism in Kerma-period communities upstream of the fourth cataract, Sudan.

Objectives: The Kingdom of Kush in today's northern Sudan and southern Egypt (ancient Nubia) is often depicted as a secondary state relative to ancient Egypt. More recent investigations have set aside Egyptocentric and western, colonialist perspectives of state development focused on control of land and agricultural surplus, examining Kushites through the lens of African-based models of mobile pastoralism in which power and authority were achieved through control of herds and alliance-building. Here, analyses of radiogenic strontium isotopes in human dental enamel are used to investigate diachronic shifts in mobility patterns linked to pastoralism and state development during the Kerma period (ca.

Twenty-first century bioarchaeology: Taking stock and moving forward.

This article presents outcomes from a Workshop entitled "Bioarchaeology: Taking Stock and Moving Forward," which was held at Arizona State University (ASU) on March 6-8, 2020. Funded by the National Science Foundation (NSF), the School of Human Evolution and Social Change (ASU), and the Center for Bioarchaeological Research (CBR, ASU), the Workshop's overall goal was to explore reasons why research proposals submitted by bioarchaeologists, both graduate students and established scholars, fared disproportionately poorly within recent NSF Anthropology Program competitions and to offer advice for increasing success. Therefore, this Workshop comprised 43 international scholars and four advanced graduate students with a history of successful grant acquisition, primarily from the United States.

Climate change, human health, and resilience in the Holocene.

Climate change is an indisputable threat to human health, especially for societies already confronted with rising social inequality, political and economic uncertainty, and a cascade of concurrent environmental challenges. Archaeological data about past climate and environment provide an important source of evidence about the potential challenges humans face and the long-term outcomes of alternative short-term adaptive strategies. Evidence from well-dated archaeological human skeletons and mummified remains speaks directly to patterns of human health over time through changing circumstances.

Correlations between preclinical BJAB assay ranking of antisense drugs and clinical trial adverse events.

This analysis sought to assess the clinical predictivity of an in vitro assay which utilized the human B-lymphoma BJAB cell line, for identification of antisense oligonucleotides (ASOs) with the potential to elicit innate immune activation in humans. Adverse events (AEs) from clinical trial data were analyzed based on prior clinical knowledge and network analysis of the clinical data to identify correlations with the BJAB assay. Clinically evaluated ASOs were ranked by the BJAB assay's mean log-fold increase in TNF expression levels.

Integrated Assessment of Phase 2 Data on GalNAc-Conjugated 2'--Methoxyethyl-Modified Antisense Oligonucleotides.

Receptor-mediated delivery of an antisense oligonucleotide (ASO) using the ligand-conjugated antisense technology is establishing a new benchmark for antisense therapeutics. The triantennary -acetylgalactosamine (GalNAc) cluster is the first conjugated ligand to yield a marked increase in ASO potency for RNA targets expressed by hepatocytes, compared to the unconjugated form. In this study, we present an integrated safety assessment of data available from randomized, placebo-controlled, phase 2 studies for six GalNAc-conjugated 2'--methoxyethyl (2'MOE)-modified ASOs.

Coelenterazine sulfotransferase from Renilla muelleri.

The luciferin sulfokinase (coelenterazine sulfotransferase) of Renilla was previously reported to activate the storage form, luciferyl sulfate (coelenterazine sulfate) to luciferin (coelenterazine), the substrate for the luciferase bioluminescence reaction. The gene coding for the coelenterazine sulfotransferase has not been identified. Here we used a combined proteomic/transcriptomic approach to identify and clone the sulfotransferase cDNA.

Early-Stage Identification and Avoidance of Antisense Oligonucleotides Causing Species-Specific Inflammatory Responses in Human Volunteer Peripheral Blood Mononuclear Cells.

A human peripheral blood mononuclear cell (PBMC)-based assay was developed to identify antisense oligonucleotide (ASO) with the potential to activate a cellular innate immune response outside of an acceptable level. The development of this assay was initiated when ISIS 353512 targeting the messenger ribonucleic acid for human C-reactive protein (CRP) was tested in a phase I clinical trial, in which healthy human volunteers unexpectedly experienced increases in interleukin-6 (IL-6) and CRP. This level of immune stimulation was not anticipated following rodent and nonhuman primate safety studies in which no evidence of exaggerated proinflammatory effects were observed.

Prevalence and Management of Sexually Transmitted Infections in Correctional Settings: A Systematic Review.

Admissions to jails and prisons in the United States number 10 million yearly; persons entering locked correctional facilities have high prevalence of sexually transmitted infections (STIs). These individuals come disproportionately from communities of color, with lower access to care and prevention, compared with the United States as a whole. Following PRISMA guidelines, the authors present results of a systematic review of literature published since 2012 on STIs in US jails, prisons, Immigration and Customs Enforcement detention centers, and juvenile facilities.

Inhibition of Prekallikrein for Hereditary Angioedema.

Background: Hereditary angioedema is characterized by recurrent and unpredictable swellings that are disabling and potentially fatal. Selective inhibition of plasma prekallikrein production by antisense oligonucleotide treatment (donidalorsen) may reduce the frequency of attacks and the burden of disease.

Methods: In this phase 2 trial, we randomly assigned, in a 2:1 ratio, patients with hereditary angioedema with C1 inhibitor deficiency to receive four subcutaneous doses of either donidalorsen (80 mg) or placebo, with one dose administered every 4 weeks.

Improvements in the Tolerability Profile of 2'--Methoxyethyl Chimeric Antisense Oligonucleotides in Parallel with Advances in Design, Screening, and Other Methods.

The development process of antisense oligonucleotides (ASOs) as therapeutic agents in humans has advanced through the implementation of chemical compound modifications as well as increasingly sophisticated toxicological preclinical screening techniques. The Ionis Integrated Safety Database was utilized to determine if advances in ASO screening and clinical lead identification methods have improved the tolerability profiles of 2'--methoxyethyl (2'MOE)-modified ASOs as a class, relative to the first 2'MOE ASO approved for use in humans, mipomersen. Tolerability was assessed by the incidence and percentage of subcutaneous doses leading to adverse events at the injection site or flu-like reactions (FLRs), as well as by the incidence of dose discontinuations due to these events.

Mothering and Incarceration: A Conceptual Model Supporting Maternal Identity.

Current literature expounds on community and personal factors contributing to the rapidly growing number of women involved in the criminal justice system. Contributing factors are complex and interwoven, leaving women with life patterns of trauma exposure, mental illness, and substance use disorders. Consequences of these life patterns and incarceration have a significant impact on maternal role attainment.

Antisense technology: an overview and prospectus.

Antisense technology is now beginning to deliver on its promise to treat diseases by targeting RNA. Nine single-stranded antisense oligonucleotide (ASO) drugs representing four chemical classes, two mechanisms of action and four routes of administration have been approved for commercial use, including the first RNA-targeted drug to be a major commercial success, nusinersen. Although all the approved drugs are for use in patients with rare diseases, many of the ASOs in late- and middle-stage clinical development are intended to treat patients with very common diseases.

Antisense technology: A review.

Antisense technology is beginning to deliver on the broad promise of the technology. Ten RNA-targeted drugs including eight single-strand antisense drugs (ASOs) and two double-strand ASOs (siRNAs) have now been approved for commercial use, and the ASOs in phase 2/3 trials are innovative, delivered by multiple routes of administration and focused on both rare and common diseases. In fact, two ASOs are used in cardiovascular outcome studies and several others in very large trials.

Ligand conjugated antisense oligonucleotide for the treatment of transthyretin amyloidosis: preclinical and phase 1 data.

Aims: Amyloidogenic transthyretin (ATTR) amyloidosis is a fatal disease characterized by progressive cardiomyopathy and/or polyneuropathy. AKCEA-TTR-L (ION-682884) is a ligand-conjugated antisense drug designed for receptor-mediated uptake by hepatocytes, the primary source of circulating transthyretin (TTR). Enhanced delivery of the antisense pharmacophore is expected to increase drug potency and support lower, less frequent dosing in treatment.

Antisense Inhibition of Prekallikrein to Control Hereditary Angioedema.

Hereditary angioedema is characterized by recurrent and unpredictable episodes of subcutaneous and mucosal swelling that can be life threatening. IONIS-PKK-L is a ligand-conjugated antisense oligonucleotide designed for receptor-mediated delivery to hepatocytes. In a compassionate-use pilot study, two patients with severe bradykinin-mediated angioedema were initially administered weekly subcutaneous injections of the unconjugated parent drug, IONIS-PKK, for 12 to 16 weeks, after which they received IONIS-PKK-L at a dose of 80 mg every 3 to 4 weeks for 7 to 8 months.

Antisense drug discovery and development technology considered in a pharmacological context.

When coined, the term "antisense" included oligonucleotides of any structure, with any chemical modification and designed to work through any post-RNA hybridization mechanism. However, in practice the term "antisense" has been used to describe single stranded oligonucleotides (ss ASOs) designed to hybridize to RNAswhile the term "siRNA" has come to mean double stranded oligonucleotides designed to activate Ago2. However, the two approaches share many common features.

mNIS+7 and lower limb function in inotersen treatment of hereditary transthyretin-mediated amyloidosis.

Introduction: Inotersen, an antisense oligonucleotide inhibitor of transthyretin (TTR) protein production, demonstrated significant benefit versus placebo in the modified Neuropathy Impairment Score (NIS) +7 neurophysiologic tests (mNIS+7) in patients with hereditary TTR-mediated amyloidosis (hATTR) with polyneuropathy. This analysis assessed the mNIS+7 components by anatomic location and the lower limb function (LLF) test.

Methods: Adults with hATTR in the NEURO-TTR trial (NCT01737398) were randomly assigned to receive weekly doses of subcutaneous inotersen 300 mg or placebo for 65 weeks.

Neuropathy symptom and change: Inotersen treatment of hereditary transthyretin amyloidosis.

Introduction: Hereditary transthyretin-mediated amyloidosis (hATTR) manifests as multisystem dysfunction, including progressive polyneuropathy. Inotersen, an antisense oligonucleotide, improved the course of neuropathic impairment in patients with hATTR in the pivotal NEURO-TTR study (NCT01737398). To determine inotersen's impact on symptoms and patients' neuropathy experience, we performed a post hoc analysis of the Neuropathy Symptoms and Change (NSC) score.

Novel antisense inhibition of diacylglycerol O-acyltransferase 2 for treatment of non-alcoholic fatty liver disease: a multicentre, double-blind, randomised, placebo-controlled phase 2 trial.

Background: Diacylglycerol-O-acyltransferase 2 (DGAT2) is one of two enzyme isoforms that catalyse the final step in the synthesis of triglycerides. IONIS-DGAT2 is an antisense oligonucleotide inhibitor of DGAT2 that is under clinical investigation for the treatment of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). The aim of this trial was to examine the safety, tolerability, and efficacy of IONIS-DGAT2 versus placebo in reducing liver fat in patients with type 2 diabetes and NAFLD.

Advancing the understanding of treponemal disease in the past and present.

Syphilis was perceived to be a new disease in Europe in the late 15th century, igniting a debate about its origin that continues today in anthropological, historical, and medical circles. We move beyond this age-old debate using an interdisciplinary approach that tackles broader questions to advance the understanding of treponemal infection (syphilis, yaws, bejel, and pinta). How did the causative organism(s) and humans co-evolve? How did the related diseases caused by Treponema pallidum emerge in different parts of the world and affect people across both time and space? How are T.

Perinatal Outcomes of Incarcerated Pregnant Women: An Integrative Review.

Incarcerated pregnant women experience psychosocial conditions that put them at risk of adverse perinatal outcomes. To examine perinatal outcomes including maternal mental health well-being, birth weight, and preterm birth, an integrated search of the literature was conducted. Findings indicate that time in prison, especially during the first trimester, results in improved birth weight and longer gestation.

IONIS-PKK a Novel Antisense Inhibitor of Prekallikrein and Bradykinin Production.

Kallikrein is the key contact system mediator responsible for the conversion of high-molecular-weight kininogen into the inflammatory vasodilator peptide bradykinin, a process regulated by C1-esterase inhibitor (C1-INH). In hereditary angioedema (HAE), genetic mutations result in deficient or dysfunctional C1-INH and dysregulation of the contact system leading to recurrent, sometimes fatal, angioedema attacks. IONIS-PKK is a second-generation 2'-O-(2-methoxyethyl)-modified chimeric antisense oligonucleotide, designed to bind and selectively reduce prekallikrein (PKK) mRNA in the liver.

Antisense Inhibition of Glucagon Receptor by IONIS-GCGR Improves Type 2 Diabetes Without Increase in Hepatic Glycogen Content in Patients With Type 2 Diabetes on Stable Metformin Therapy.

Objective: To evaluate the safety and efficacy of IONIS-GCGR, a 2'--methoxyethyl antisense oligonucleotide targeting the glucagon receptor (GCGR), and the underlying mechanism of liver transaminase increases in patients with type 2 diabetes on stable metformin therapy.

Research Design And Methods: In three phase 2, randomized, double-blind studies, patients with type 2 diabetes on metformin received weekly subcutaneous injections of IONIS-GCGR (50-200 mg) or placebo for 13 or 26 weeks.

Results: Significant reductions in HbA were observed after IONIS-GCGR treatment versus placebo at week 14 (-2.
