Implementation and Evaluation Strategies for Pharmacogenetic Testing in Hospital Settings: A Scoping Review.
Pharmacogenetic testing in clinical settings has improved the safety and efficacy of drug treatment. There is a growing number of studies evaluating pharmacogenetic implementation and identifying barriers and facilitators. However, no review has focused on bridging the gap between identifying barriers and facilitators of testing and the clinical strategies adopted in response. This review was conducted to understand the implementation and evaluation strategies of pharmacogenetic testing programs. A PRISMA-compliant scoping review was conducted. The included studies discussed pharmacogenetic testing programs implemented in a hospital setting. Quantitative, qualitative, and mixed design methods were included. A total of 232 of the 7043 articles that described clinical pharmacogenetic programs were included. The most common specialties that described pharmacogenetic implementation were psychiatry (26%) and oncology (16%), although many studies described institutional programs implemented across multiple specialties (19%). Different specialties reported different clinical outcomes, but all reported similar program performance indicators, such as test uptake and the number of times the test recommendations were followed. There were benefits and drawbacks to delivering test results through research personnel, pharmacists, and electronic alerts, but active engagement of physicians was necessary for the incorporation of pharmacogenetic results into clinical decision making. Further research is required on the maintenance and sustainability of pharmacogenetic testing initiatives. These findings provide an overview of the implementation and evaluation strategies of different specialties that can be used to improve pharmacogenetic testing.

Daptomycin Dosage Optimization in Renal Impairment Using Model-Informed Precision Dosing.
Daptomycin's efficacy and toxicity are closely related to its exposure, which can vary widely among individuals. The patient, a 59-year-old male with an estimated glomerular filtration rate (eGFR) of 12 mL/min/1.73 m² and a weight of 64 kg, was treated with 850 mg of daptomycin every other day for infective endocarditis caused by methicillin-resistant Staphylococcus aureus (MRSA). For patients with an estimated glomerular filtration rate of less than 30 mL/min/1.73 m², the dosing recommendations are not explicitly defined in the endocarditis guidelines. Subsequently, the pharmacology department was contacted to adjust the dosage. A population pharmacokinetic model developed by Dvorchik et al. was used for Bayesian estimation of the patient's pharmacokinetic parameters. The 24-hour area under the curve (AUC24) of daptomycin was calculated at steady state using peak and trough plasma samples. The minimum inhibitory concentration (MIC) of the MRSA strain was 0.25 mg/L. An AUC24/MIC ratio below 666 is associated with higher mortality risk, while an AUC24 above 939 h·mg/L correlates with increased risk of muscular toxicity. Initial AUC24 estimation was 1091 h·mg/L. Following a dosage reduction to 700 mg every other day, the AUC24 increased to 1600 h·mg/L. Further reduction to 500 mg every other day brought the AUC24 down to 750 h mg/L, with two subsequent measurements showing consistent AUC24 values of 500 h·mg/L, which is within the target range. Daptomycin ended 6 weeks after the initial negative blood culture, with no adverse effects or recurrence of MRSA infection. This case underscores the need for therapeutic drug monitoring and a multidisciplinary approach to adjust daptomycin doses in patients with renal impairment.

Dose Estimation Utility in a Population Pharmacokinetic Analysis of Inhaled Δ9-Tetrahydrocannabinol Cannabis Market Products in Occasional and Daily Users.
Unusually high variability in blood Δ9-tetrahydrocannabinol (THC) concentrations have been observed in subjects inhaling similar cannabis products over similar time periods when consumption is ad libitum. This makes simple gravimetric dose estimation a poor predictor of THC exposure. Population pharmacokinetic analyses of blood THC concentration versus time data are routinely used to estimate pharmacokinetic parameters. The aim of this study was to estimate the inhaled dose of THC in occasional and daily users of high potency market cannabis. Blood THC concentrations were measured for 135 minutes from 29 participants who either smoked high concentration flower or inhaled concentrates ad libitum during a 15-minute session. Frequent blood samples were obtained over the following 135 minutes. The estimated central and rapidly equilibrating volumes of distribution of a 3-compartment model were 19.9 ± 1.2 and 51.6 ± 4.7 L whereas the intercompartmental clearances were 1.65 ± 0.14 and 1.75 ± 0.10 L/min, respectively. Covariate-adjusted analysis revealed that the estimated inhaled THC dose was considerably less among occasional users compared with daily users. Three-compartment pharmacokinetics of THC did not differ among the 3 user groups, and the early phase (first 135 minutes postinception of inhalation) kinetics were similar to those previously described after smoking low potency cannabis products. Therefore, inhaled THC dose can be estimated from pharmacokinetic data and covariate-driven adjustments can be used to estimate THC doses, based on the participant cannabis usage pattern (occasional versus daily), improving the accuracy of THC exposure estimates compared with those derived from weighed THC content alone.

The Case of Dolutegravir Plus Darunavir Antiretroviral Regimens: Is It Always Useful to Double the Drug Doses? A Short Communication.
Antiretroviral drug combinations affect dolutegravir trough concentrations. Here, the authors focused on dolutegravir plus booster darunavir antiretroviral regimens to investigate the effect of the booster and/or timing of drug administration on dolutegravir and darunavir plasma trough concentrations. This retrospective observational study included consecutive people with HIV (PWH) receiving dolutegravir plus booster darunavir antiretroviral regimens for at least 3 months, with at least one assessment of dolutegravir and darunavir plasma trough concentrations. A total of 200 drug therapeutic drug monitoring results from 116 PWH were included. Dolutegravir and darunavir trough concentrations ranged, respectively, from 70 to 3648 mcg/L and from 102 to 11,876 mcg/L. The antiretroviral drug combination associated with the highest dolutegravir trough concentration was dolutegravir plus darunavir/cobicistat, both once daily (1410 ± 788 mcg/L), whereas dolutegravir once daily plus darunavir/ritonavir twice daily had the lowest trough concentrations (686 ± 481 mcg/L). Doubling the dose of dolutegravir did not significantly increase drug trough concentrations compared with that of once-daily regimens. Instead, the highest darunavir trough concentrations were with ritonavir (2850 ± 1456 mcg/L, P < 0.05 versus cobicistat-based regimens). Doubling the drug dose resulted in a significant increase in the darunavir trough concentration (4445 ± 2926 mcg/L, P < 0.05). Dolutegravir trough concentrations were significantly reduced in PWH receiving darunavir/ritonavir twice daily. This evidence should be carefully considered in clinical conditions requiring higher dolutegravir exposure, such as in the presence of drug-drug interactions with drugs known to reduce dolutegravir bioavailability or in highly experienced PWH.

Association of Plasma Cabozantinib Concentration With Treatment Response and Adverse Events in Japanese Patients With Advanced Renal Cell Carcinoma.
Cabozantinib is highly effective against advanced renal cell carcinoma (RCC). However, approximately 60% of the patients require a dose reduction due to severe adverse events. Although associations between trough concentrations of cabozantinib and its efficacy and safety have been reported in other countries, reports on Japanese patients are unavailable. Therefore, we investigated the association of cabozantinib trough concentration with therapeutic efficacy and adverse events in Japanese patients with RCC and evaluated the usefulness of therapeutic drug monitoring. In this prospective observational study, we measured the trough concentrations of cabozantinib in 10 Japanese patients with RCC enrolled between May 2022 and September 2023. The associations of trough concentration with treatment response, as determined by RECIST 1.1, and the occurrence of grade 2 or higher adverse events were assessed. Trough concentration was higher in patients with controlled cancer than in those with progressive cancer (1024 ± 352 versus 457 ± 216 ng/mL, P = 0.035). In addition, patients with grade 2 or higher adverse events showed a significantly higher trough concentration than those without (1560 ± 513 versus 807 ± 319 ng/mL, P = 0.032). In particular, grade 2 or higher dysgeusia, anorexia, fatigue, and dyspepsia significantly correlated with trough concentrations. This is the first clinical study to demonstrate a correlation between cabozantinib trough concentration, therapeutic efficacy, and adverse events in Japanese patients with RCC. The therapeutic drug monitoring of cabozantinib could be useful for improving therapeutic efficacy and avoiding serious adverse events.
