A Pilot Randomized Study of NAT2 and YEATS4 Pharmacogenetic Return of Results in Adults with Hypertension and African Ancestry: The GUARDD‐US PGx Study

Clinical Pharmacology &Therapeutics, EarlyView.
Almost half of individuals with hypertension fail to achieve recommended blood pressure (BP) goals. Pharmacogenetic gene‐drug interactions may alter the efficacy of antihypertensive agents. We conducted a multicenter randomized controlled sub‐study of participants (N = 1874) with hypertension and self‐reported African ancestry to determine whether ...

The EMA Qualification Opinion for CYP Inhibition‐Mediated Drug–Drug Interaction Predictions: Implications for PBPK Credibility Assessment in the Era of ICH M15

Clinical Pharmacology &Therapeutics, EarlyView.
Clinical pharmacology and pharmacometrics teams are now being encouraged to implement the ICH M15 framework in drug development to support model‐informed decisions in regulatory submissions. Although model performance is an important component of model evaluation, regulatory confidence also depends on the intended context of use (CoU) and the ...

Patients with Chronic Inflammatory Diseases Can Experience Higher Exposure of Small Molecule Drugs than Healthy Volunteers: An Analysis of Recently Approved Drugs

Clinical Pharmacology &Therapeutics, EarlyView.
Chronic inflammation has long been known to downregulate the activity of certain cytochrome P450 (CYP) enzymes—the main enzymes responsible for the phase I metabolism of many small molecule drugs—potentially leading to higher exposures in patients with chronic inflammatory diseases compared to healthy volunteers. Neglecting this potential difference in

Intra‐Individual Variability of Blood and Urinary Steroid Markers and the Response to Codeine Intake in Healthy Men and Women

Drug Testing and Analysis, EarlyView.
Short‐term codeine administration (1–3 days) caused individual alterations in Athlete Biological Passport steroid markers, including elevated urinary T/E ratios and decreased serum testosterone concentrations below individual thresholds, despite no significant changes at the group level.
