Dose Optimization of rhIL-7-hyFc for Patients With Lymphopenia Using a Neonatal Fc Receptor-Mediated Recycling-Based and Target-Mediated Drug Disposition Pharmacokinetic Model.

Recombinant human interleukin-7 hybrid Fc (rhIL-7-hyFc) is a homodimer of rhIL-7 fused to a hyFc. Exogenous IL-7 promotes T cell proliferation and increases lymphocyte count, making it a potential treatment option for lymphopenia and cancer. To improve therapeutic efficacy, rhIL-7-hyFc was developed as a long-acting IL-7.

Comparative Safety of Short-Acting Opioid Dose Escalation and Long-Acting Opioid Initiation in Nursing Home Residents.

Background: For patients with continued pain while receiving an initial course of a short-acting opioid (SAO), clinicians may intensify the opioid regimen by escalating the SAO dose or initiating a long-acting opioid (LAO). The objective of this study was to assess the comparative safety of opioid intensification regimens in nursing home residents with nonmalignant pain.

Methods: We conducted a retrospective cohort analysis of US long-stay nursing home residents identified from the national Minimum Data Set (MDS) 3.

Effect of choline alfoscerate in older adult patients with dementia: an observational study from the claims data of national health insurance.

Background: Choline alfoscerate, a cholinergic precursor with limited evidence of efficacy in dementia management, has been used for various cognitive impairments in Korea. Partly due to its insurance coverage, this agent appears to incur significant expense for the insurance system. Thus, we aimed to describe choline alfoscerate prescription patterns and analyze their long-term effects in an older adult cohort with dementia.

Prothionamide Dose Optimization Using Population Pharmacokinetics for Multidrug-Resistant Tuberculosis Patients.

Prothionamide, a second-line drug for multidrug-resistant tuberculosis (MDR-TB), has been in use for a few decades. However, its pharmacokinetic (PK) profile remains unclear. This study aimed to develop a population PK model for prothionamide and then apply the model to determine the optimal dosing regimen for MDR-TB patients.

Model-Based Equivalent Dose Optimization to Develop New Donepezil Patch Formulation.

Donepezil patch was developed to replace the original oral formulation. To accurately describe the pharmacokinetics of donepezil and investigate compatible doses between two formulations, a population pharmacokinetic model for oral and transdermal patches was built based on a clinical study. Plasma donepezil levels were analyzed via liquid chromatography/tandem mass spectrometry.
