Therapeutic Anti-Tumor Efficacy of DC-Based Vaccines Targeting TME-Associated Antigens Is Improved When Combined with a Chemokine-Modulating Regimen and/or Anti-PD-L1.

We previously reported that dendritic cell (DC)-based vaccines targeting antigens expressed by tumor-associated vascular endothelial cells (VECs) and pericytes effectively control tumor growth in translational mouse tumor models. In the current report, we examined whether the therapeutic benefits of such tumor blood vessel antigen (TBVA)-targeted vaccines could be improved by the cotargeting of tumor antigens in the s.c.

Inter-Antibody Variability in the Clinical Pharmacokinetics of Monoclonal Antibodies Characterized Using Population Physiologically Based Pharmacokinetic Modeling.

The objective of this work was to develop a population physiologically based pharmacokinetic (popPBPK) model to characterize the variability in the clinical PK of monoclonal antibodies (mAbs) following intravenous (IV) and subcutaneous (SC) administration. An extensive literature search was conducted and clinical PK data for FDA-approved as well as non-approved mAbs were collected. Training and validation datasets of 44 and 9 mAbs exhibiting linear pharmacokinetics were used for model development.

Evaluation of safety outcomes between nivolumab regimens with differing dosing patterns.

Background: Real-world safety outcomes between the two flat-dose nivolumab regimens demonstrated to be similar in a study of adjuvant nivolumab recipients for melanoma. However, this study was limited by a single oncology patient population, a small sample size, and insufficient study power. The primary objective of this study was to evaluate the incidence of immunotherapy-related adverse effects (irAEs) between nivolumab regimens with differing dosing patterns in various solid tumor patient populations.

Sotorasib (960 mg or 240 mg) once daily in patients with previously treated KRAS G12C-mutated advanced NSCLC.

Background: Sotorasib 960 mg once daily is approved to treat KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC). Sotorasib exhibits non-dose proportional pharmacokinetics and clinical responses at lower doses; therefore, we evaluated the efficacy and safety of sotorasib 960 mg and 240 mg.

Methods: In this phase 2, randomized, open-label study, adults with KRAS G12C-mutated advanced NSCLC received sotorasib 960 mg or 240 mg once daily.

Complex intracranial aneurysms: a DELPHI study to define associated characteristics.

Purpose: Intracranial aneurysms present significant health risks, as their rupture leads to subarachnoid haemorrhage, which in turn has high morbidity and mortality rates. There are several elements affecting the complexity of an intracranial aneurysm. However, criteria for defining a complex intracranial aneurysm (CIA) in open surgery and endovascular treatment could differ, and actually there is no consensus on the definition of a "complex" aneurysm.

Immobilized NRG1 Accelerates Neural Crest like Cell Differentiation Toward Functional Schwann Cells Through Sustained Erk1/2 Activation and YAP/TAZ Nuclear Translocation.

Neural Crest cells (NC) are a multipotent cell population that give rise to a multitude of cell types including Schwann cells (SC) in the peripheral nervous system (PNS). Immature SC interact with neuronal axons via the neuregulin 1 (NRG1) ligand present on the neuronal surface and ultimately form the myelin sheath. Multiple attempts to derive functional SC from pluripotent stem cells have met challenges with respect to expression of mature markers and axonal sorting.

pyDarwin machine learning algorithms application and comparison in nonlinear mixed-effect model selection and optimization.

Forward addition/backward elimination (FABE) has been the standard for population pharmacokinetic model selection (PPK) since NONMEM® was introduced. We investigated five machine learning (ML) algorithms (Genetic algorithm [GA], Gaussian process [GP], random forest [RF], gradient boosted random tree [GBRT], and particle swarm optimization [PSO]) as alternatives to FABE. These algorithms were applied to PPK model selection with a focus on comparing the efficiency and robustness of each of them.

The Impact of High-density Lipoprotein Cholesterol (HDL-C) Levels and Risk of Movement Disorders in Patients Taking Antipsychotics.

Introduction: Well-known adverse events of antipsychotics are movement disorders, or extrapyramidal symptoms, such as drug-induced parkinsonism and tardive dyskinesia.

Objective: With new evidence suggesting a link between low high-density lipoprotein cholesterol (HDL-C) and risk of Parkinson's disease, this study sought to investigate if that link also translated to patients taking antipsychotics with low HDL-C and an increased risk for developing a movement disorder.

Design: Adult patients (n=89) at an inpatient state psychiatric facility taking at least one antipsychotic with at least one HDL-C level were assessed for signs of a movement disorder through their history and physical, progress notes, and Abnormal Involuntary Movement Scale (AIMS) score.
