The Discovery and Preclinical Profile of ALG-000184, a Prodrug of the Potent Hepatitis B Virus Capsid Assembly Modulator ALG-001075.

Chronic hepatitis B (CHB) represents a significant unmet medical need with few options beyond lifelong treatment with nucleoside analogues, which rarely leads to a functional cure. Novel agents that reduce levels of HBV DNA, RNA and other viral antigens could lead to better treatment outcomes. The capsid assembly modulator (CAM) class of compounds represents an important modality for chronic suppression and to improve functional cure rates, either alone or in combination.

Discovery and Preclinical Profile of ALG-055009, a Potent and Selective Thyroid Hormone Receptor Beta (THR-β) Agonist for the Treatment of MASH.

Agonists of thyroid hormone receptor β (THR-β) decreased LDL cholesterol (LDL-C) and triglyceride (TG) levels in human clinical trials for patients with dyslipidemia. The authors present the highly potent and selective compound ALG-055009 () as a potential best in class THR-β agonist. The high metabolic stability and good permeability translated well in vivo to afford a long in vivo half-life pharmacokinetic profile with limited liability for DDI, and it overcomes certain drawbacks seen in recent clinical candidates.

Historical Structural Racism in the Built Environment and Physical Health among Residents of Allegheny County, Pennsylvania.

Historical structural racism in the built environment contributes to health inequities, yet to date, research has almost exclusively focused on racist policy of redlining. We expand upon this conceptualization of historical structural racism by examining the potential associations of probable blockbusting, urban renewal, and proximity to displacement from freeway construction, along with redlining, to multiple contemporary health measures. Analyses linked historical structural racism, measured continuously at the census-tract level using archival data sources, to present-day residents' physical health measures drawn from publicly accessible records for Allegheny County, Pennsylvania.

An in vivo duck hepatitis B virus model recapitulates key aspects of nucleic acid polymer treatment outcomes in chronic hepatitis B patients.

Nucleic acid polymers (NAPs) are an attractive treatment modality for chronic hepatitis B (CHB), with REP2139 and REP2165 having shown efficacy in CHB patients. A subset of patients achieve functional cure, whereas the others exhibit a moderate response or are non-responders. NAP efficacy has been difficult to recapitulate in animal models, with the duck hepatitis B virus (DHBV) model showing some promise but remaining underexplored for NAP efficacy testing.

Historical Structural Racism in the Built Environment and Contemporary Children's Opportunities.

Background And Objectives: There are well-documented links between structural racism and inequities in children's opportunities. Yet, when it comes to understanding the role of the built environment, a disproportionate focus on redlining obscures other historical policies and practices such as blockbusting, freeway displacement, and urban renewal that may impact contemporary child development. We hypothesized that historical structural racism in Allegheny County, Pennsylvania's, built environment would be associated with fewer contemporary educational, socioeconomic, and health opportunities.

Economic hardship and adolescent behavioral outcomes: Within- and between-family associations.

Understanding how youth perceive household economic hardship and how it relates to their behavior is vital given associations between hardship and behavioral development. Yet, most studies ignore youth's own perceptions of economic hardship, instead relying solely on caregiver reports. Moreover, the literature has tended to treat economic hardship as a stable force over time, rather than a volatile one that varies month-to-month.

A quality improvement initiative to reduce antibiotic use in transient tachypnea of the newborn.

Objective: Evidence suggests that antibiotics are unnecessary in infants with transient tachypnea of the newborn (TTN) that are low-risk for early-onset sepsis. The aim was to reduce ampicillin and gentamicin days of therapy (DOT) in infants with suspected TTN by 10% within 12 months.

Study Design: We used the Model for Improvement to test interventions from August 2019 to September 2021 to decrease antibiotic utilization in low-risk infants with TTN.

Tumor Regression upon Intratumoral and Subcutaneous Dosing of the STING Agonist ALG-031048 in Mouse Efficacy Models.

Stimulator of interferon genes (STING) agonists have shown potent anti-tumor efficacy in various mouse tumor models and have the potential to overcome resistance to immune checkpoint inhibitors (ICI) by linking the innate and acquired immune systems. First-generation STING agonists are administered intratumorally; however, a systemic delivery route would greatly expand the clinical use of STING agonists. Biochemical and cell-based experiments, as well as syngeneic mouse efficacy models, were used to demonstrate the anti-tumoral activity of ALG-031048, a novel STING agonist.

Nutrition-based implications and therapeutics in the development and recovery of bronchopulmonary dysplasia.

Premature births account for over 10% of live births worldwide. Bronchopulmonary dysplasia (BPD) represents a severe sequela in neonates born very prematurely and remains the most common chronic neonatal lung disease, often leading to serious adverse consequences in adulthood. Nutrition plays a crucial role in lung development and repair.

Novel non-HAP class A HBV capsid assembly modulators have distinct and profiles.

Chronic hepatitis B is the most important cause of liver cancer worldwide and affects more than 290 million people. Current treatments are mostly suppressive and rarely lead to a cure. Therefore, there is a need for novel and curative drugs that target the host or the causative agent, hepatitis B virus itself.

Class A capsid assembly modulator RG7907 clears HBV-infected hepatocytes through core-dependent hepatocyte death and proliferation.

Background And Aims: Effective therapies leading to a functional cure for chronic hepatitis B are still lacking. Class A capsid assembly modulators (CAM-As) are an attractive modality to address this unmet medical need. CAM-As induce aggregation of the HBV core protein (HBc) and lead to sustained HBsAg reductions in a chronic hepatitis B mouse model.

Assessment of lung ventilation of premature infants with bronchopulmonary dysplasia at 1.5 Tesla using phase-resolved functional lung magnetic resonance imaging.

Background: The most common chronic complication of preterm birth is bronchopulmonary dysplasia (BPD), widely referred to as chronic lung disease of prematurity. All current definitions rely on characterizing the disease based on respiratory support level and do not provide full understanding of the underlying cardiopulmonary pathophysiology.

Objective: To evaluate a rapid functional lung imaging technique in premature infants and to quantitate pulmonary ventilation using 1.

The Substitutions L50F, E166A, and L167F in SARS-CoV-2 3CLpro Are Selected by a Protease Inhibitor and Confer Resistance To Nirmatrelvir.

The SARS-CoV-2 main protease (3CLpro) has an indispensable role in the viral life cycle and is a therapeutic target for the treatment of COVID-19. The potential of 3CLpro-inhibitors to select for drug-resistant variants needs to be established. Therefore, SARS-CoV-2 was passaged in the presence of increasing concentrations of ALG-097161, a probe compound designed in the context of a 3CLpro drug discovery program.

An Ethics and Social-Justice Approach to Collecting and Using Demographic Data for Psychological Researchers.

The collection and use of demographic data in psychological sciences has the potential to aid in transforming inequities brought about by unjust social conditions toward equity. However, many current methods surrounding demographic data do not achieve this goal. Some methods function to reduce, but not eliminate, inequities, whereas others may perpetuate harmful stereotypes, invalidate minoritized identities, and exclude key groups from research participation or access to disseminated findings.

One vaccine to counter many diseases? Modeling the economics of oral polio vaccine against child mortality and COVID-19.

Introduction: Recent reviews summarize evidence that some vaccines have heterologous or non-specific effects (NSE), potentially offering protection against multiple pathogens. Numerous economic evaluations examine vaccines' pathogen-specific effects, but less than a handful focus on NSE. This paper addresses that gap by reporting economic evaluations of the NSE of oral polio vaccine (OPV) against under-five mortality and COVID-19.

Improving Breast Cancer Family Caregivers' Palliative Care Literacy: A Pilot Randomized Trial.

Self- and family management (SFM) refers to patients' and family caregivers' activities to co-manage illness. Two barriers to SFM are low palliative care literacy and lack of goals of care communication, which potentially result in SFM activities that are unsupportive of patients' goals. Managing Cancer Care: A Caregiver's Guide (MCC-CG) aims to improve palliative care literacy and communication within a SFM training program.

Integrating Palliative Care Into Self-management of Breast Cancer: A Pilot Randomized Controlled Trial.

Background: Breast cancer patients may not be well-informed about palliative care, hindering its integration into cancer self-management.

Objective: The aim of this study was to test Managing Cancer Care: A Personal Guide (MCC-PT), an intervention to improve palliative care literacy and cancer self-management.

Methods: This was a single-blind pilot randomized controlled trial to evaluate the feasibility/acceptability and intervention effects of MCC-PT on palliative care literacy, self-management behaviors/emotions, and moderation by demographic/clinical characteristics.

Mechanism of action of hepatitis B virus S antigen transport-inhibiting oligonucleotide polymer, STOPS, molecules.

A functional cure of chronic hepatitis B requires eliminating the hepatitis B virus (HBV)-encoded surface antigen (HBsAg), which can suppress immune responses. STOPS are phosphorothioated single-stranded oligonucleotides containing novel chemistries that significantly reduce HBsAgs produced by HBV-infected liver cells. The STOPS molecule ALG-10000 functions inside cells to reduce the levels of multiple HBV-encoded molecules.

An observational case series of targeted virtual geriatric medicine and palliative care consults for hospitalized older adults with COVID-19.

Background: COVID-19 presents unique challenges to the care of hospitalized older adults, including fractured lines of communication and uncertainty surrounding long term trajectories in cognition and function. Geriatric medicine and palliative care clinicians bring specialized training in facilitating communication in the face of uncertainty. Insurance expansion of virtual visits enabled inpatient virtual consultation, which can preserve personal protective equipment and minimize exposure to clinicians.

Old vaccines for new infections: Exploiting innate immunity to control COVID-19 and prevent future pandemics.

The COVID-19 pandemic triggered an unparalleled pursuit of vaccines to induce specific adaptive immunity, based on virus-neutralizing antibodies and T cell responses. Although several vaccines have been developed just a year after SARS-CoV-2 emerged in late 2019, global deployment will take months or even years. Meanwhile, the virus continues to take a severe toll on human life and exact substantial economic costs.

ALG-097111, a potent and selective SARS-CoV-2 3-chymotrypsin-like cysteine protease inhibitor exhibits in vivo efficacy in a Syrian Hamster model.

There is an urgent need for antivirals targeting the SARS-CoV-2 virus to fight the current COVID-19 pandemic. The SARS-CoV-2 main protease (3CLpro) represents a promising target for antiviral therapy. The lack of selectivity for some of the reported 3CLpro inhibitors, specifically versus cathepsin L, raises potential safety and efficacy concerns.
