Population pharmacokinetics of peramivir in healthy volunteers and influenza patients.

ABSTRACT:

Unlabelled

Peramivir is an intravenous anti-influenza agent that inhibits viral growth by selectively inhibiting neuraminidase in human influenza A and B viruses. To characterize its pharmacokinetics, a population pharmacokinetic analysis of peramivir was performed using 3,199 plasma concentration data samples from 332 subjects in six clinical studies in Japan and the United States, including studies with renal impairment subjects, elderly subjects, and influenza patients. A three-compartment model well described the plasma concentration data for peramivir, and creatinine clearance was found to be the most important factor influencing clearance. Age and body weight were also found to be covariates for clearance and the volume of distribution, respectively. No difference in pharmacokinetics was found between genders or between Japanese and U.S.

Subjects

Small differences in pharmacokinetics were observed between uninfected subjects and influenza patients (clearance was 18% higher and the volume of distribution was 6% lower in influenza patients). Monte Carlo simulations indicated that single adjusted doses of 1/3- and 1/6-fold for patients with moderate and severe renal impairment, respectively, would give areas under the curve comparable to those for patients with normal renal function. The population pharmacokinetic model developed for peramivir should be useful for understanding its pharmacokinetic characteristics and for dose adjustment on the basis of renal function.

Project description:Finafloxacin is a novel fluoroquinolone with increased antibacterial activity at acidic pH and reduced susceptibility to several resistance mechanisms. A phase II study revealed a good efficacy/safety profile in patients with complicated urinary tract infections (cUTIs), while the pharmacokinetics was characterized by highly variable concentration-versus-time profiles, suggesting the need for an elaborated pharmacokinetic model. Data from three clinical trials were evaluated: 127 healthy volunteers were dosed orally (n = 77) or intravenously (n = 50), and 139 patients with cUTI received finafloxacin intravenously. Plasma (2,824 samples from volunteers and 414 samples from patients) and urine (496 samples from volunteers and 135 samples patients) concentrations were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). NONMEM was used to build a population pharmacokinetic model, and pharmacokinetic/pharmacodynamic relationships were investigated via simulations and logistic regression. A two-compartment model with first-order elimination described the data best (central volume of distribution [Vc] and peripheral volume of distribution [Vp] of 47 liters [20%] and 43 liters [67%], respectively, and elimination clearance and intercompartmental clearance of 21 liters/h [54%] and 2.8 liters/h [57%], respectively [median bootstrap estimates {coefficients of variation}]). Vc increased with body surface area, and clearance was reduced in patients (-29%). Oral absorption was described best by parallel first- and zero-order processes (bioavailability of 75%). No pharmacodynamic surrogate parameter of clinical/microbiological outcome could be identified, which depended exclusively on the MIC of the causative pathogens. Despite the interindividual variability, the present data set does not support covariate-based dose adjustments. Based on the favorable safety and efficacy data, the clinical relevance of the observed variability appears to be limited. (This study has been registered at ClinicalTrials.gov under identifier NCT01928433.).

Project description:Finafloxacin is a novel fluoroquinolone exhibiting enhanced activity under acidic conditions and a broad-spectrum antibacterial profile. The present study assessed the pharmacokinetic properties and the safety and tolerability of finafloxacin following intravenous infusions. In this mixed-parallel-group, crossover study, healthy male and female volunteers received single ascending doses (18 volunteers, 200 to 1,000 mg) or multiple ascending doses (40 volunteers, 600 to 1,000 mg) of finafloxacin or placebo. Plasma and urine samples were collected by a dense sampling scheme to determine the pharmacokinetics of finafloxacin using a noncompartmental approach. Standard safety and tolerability data were documented. Finafloxacin had a volume of distribution of 90 to 127 liters (range) at steady state and 446 to 550 liters at pseudoequilibrium, indicating the elimination of a large fraction before pseudoequilibrium was reached. Areas under the concentration-time curves and maximum plasma concentrations (geometric means) increased slightly more than proportionally (6.73 to 45.9 ?g · h/ml and 2.56 to 20.2 ?g/ml, respectively), the terminal elimination half-life increased (10.6 to 17.1 h), and the urinary recovery decreased (44.2% to 31.7%) with increasing finafloxacin doses (single doses of 200 to 1,000 mg). The pharmacokinetic profiles suggested multiphasic elimination by both glomerular filtration and saturable tubular secretion. The values of the parameters were similar for single and multiple administrations. The coefficient of variation for the between-subject variability of exposure ranged from 10% (?600 mg) to 38% (>600 mg). Adverse events were mild and nonspecific, with no dependence of adverse events on dose or treatment (including placebo) being detected. Despite a relatively high interindividual variability at higher doses, the level of exposure following intravenous administration of finafloxacin appears to be predictable. Individual elimination processes should be evaluated in more detail. Finafloxacin exhibited a favorable safety and tolerability profile. (This study has been registered at ClinicalTrials.gov under registration no. NCT01910883.).

Project description:BackgroundVivax malaria is a neglected disease. There is an irrefutable need for better treatments with higher acceptability and efficacy. The treatment efficacy is influenced by many factors, including bioavailability. Hence, a straightforward strategy to improve vivax malaria treatment efficacy is the deployment of good quality formulations of primaquine and chloroquine. As these treatments were developed more than 70 years ago, many of the available data on blood levels of both drugs are based on obsolete analytical methodologies or pharmaceutical formulations, which are not available anymore. Herein, the results of three bioequivalence studies are presented, providing individual pharmacokinetic data on chloroquine and primaquine of more than a hundred healthy volunteers and using up-to-date analytical methods.MethodsThree trials were designed as a single centre, randomized, single dose, open label, fasting, crossover bioequivalence studies comparing a new coated chloroquine tablet to the uncoated tablet, and 5 and 15 mg primaquine formulations to either an international reference product or the currently distributed tablets. Plasma concentrations of chloroquine and primaquine were measured using a validated HPLC-MS/MS method in accordance with current international regulatory requirements for bio-analytical methods.ResultsIn total, a hundred eleven healthy volunteers of both genders were included in the three studies (n = 32; 30 and 56 respectively). No serious adverse events occurred. Drugs levels were measured in 5,520 blood samples. The estimated ratio of the geometric means of Cmax, AUC0-t and AUC0-inf of test and reference drugs and their 90% CI for chloroquine 150 mg, primaquine 15 mg and primaquine 5 mg were: 95.33% (89.18; 101.90), 86. 85% (82.61; 91.31), and 84.45% (76.95; 92.67); 93.28% (81.76; 106.41), 94.52% (86.13; 103.73) and 93.93% (85.83; 102.79); 97.44% (90.60; 104.78), 93.70% (87.04; 100.87) and 91.36% (85.27; 97.89), respectively. As Cmax and AUC0-t 90% CI were within the acceptance interval of 80-125% in all cases, the formulations tested were bioequivalent.ConclusionsIn conclusion, the three studies provided detailed chloroquine and primaquine pharmacokinetic data in accordance with current regulatory standards. Together with other open data initiatives, this individual data may increase the accuracy of pharmacokinetic models guiding best dose, new combinations, regimens and formulations to optimize the current chloroquine and primaquine treatments for vivax malaria. The data presented here may support the deployment of high-quality drugs and evidence-based public health policies.
