An IQ Consortium Perspective on the FDA Guidance for Assessment of Pharmacokinetics in Participants With Impaired Renal Function

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 838-845, April 2026.
The FDA published guidance on assessing pharmacokinetics (PK) in participants with impaired renal function in 2024. The IQ CPLG Organ Impairment Working Group summarized the industry’s perspective on this guidance by highlighting a few key updates in the 2024 guidance, including: (1) the recommendation of using estimated glomerular filtration rate ...

Quantitative Systems Toxicology Modeling with DILIsym to Support Phase 3 Dose Selection for Fezolinetant

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 1016-1024, April 2026.
Fezolinetant is a first‐in‐class, selective, non‐hormonal, neurokinin 3 receptor antagonist that is approved for the treatment of moderate to severe vasomotor symptoms due to menopause. In a phase 2b clinical study (n = 352), nine study participants experienced elevations in serum transaminases exceeding three times the upper limit of normal.

Analysis of Regulatory Inhalation Unit Risk Estimates for Cobalt: Comparison to Epidemiological Data

open access: yesRisk Analysis, Volume 46, Issue 4, April 2026.
ABSTRACT Several cancer potency estimates have been proposed by regulatory agencies to characterize the dose response of cobalt and/or cobalt compounds. The objective of this research is to investigate whether these proposed cancer potency estimates for certain cobalt substances align with the available epidemiology literature.

Physiologically based pharmacokinetic model combined with a clinical lactation study to determine doravirine concentrations in human breastmilk

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 3, Page 952-959, March 2026.
Aims To determine breastmilk concentrations of doravirine via PBPK modelling in combination with a clinical lactation study. As women living with HIV are not able to cease antiretroviral therapy during lactation, it is necessary to establish drug transfer into breastmilk to determine exposure of the infant to antiretroviral drugs and potential risk of ...

Absolute Bioavailability and Absorption, Distribution, Metabolism, and Excretion of [14C]Xevinapant, a Potent, Oral, Small‐Molecule IAP Inhibitor

open access: yesClinical Pharmacology in Drug Development, Volume 15, Issue 3, March 2026.
Abstract This Phase 1, open‐label, 2‐part, single‐dose study aimed to investigate the pharmacokinetics, metabolism, and excretion of xevinapant, a small molecule inhibitor of apoptosis proteins (IAPs), in healthy male subjects. Part 1 focused on determining the mass balance recovery, pharmacokinetics, and metabolic profile of [14C]xevinapant following ...

Non-equilibrium entangled steady state of two independent two-level systems

open access: yes, 2011
We determine and study the steady state of two independent two-level systems weakly coupled to a stationary non-equilibrium environment. Whereas this bipartite state is necessarily uncorrelated if the splitting energies of the two-level systems are ...

Population Pharmacokinetic Modeling Practice of Time‐Varying Clearance: Insights from a First‐in‐Human Study Case

open access: yesThe Journal of Clinical Pharmacology, Volume 66, Issue 3, March 2026.
Abstract Accurate characterization of time‐varying clearance (CL) is critical during early drug development, as it informs clinical study design and dosing strategies for future trials. However, detecting and modeling time‐varying clearance is challenging due to limited data availability in early clinical development.
