Pharmacokinetics comparison of two pegylated interferon alfa formulations in healthy volunteers.

ABSTRACT: BACKGROUND:Several countries have used pegylation technology to improve the pharmacokinetic properties of essential drugs. Recently, a novel interferon alfa-2b protein conjugated to four-branched 12 kDa polyethylene glycol molecules was developed jointly between Cuba and Brazil. The aim of this study was to compare the pharmacokinetic properties of BIP48 (pegylated interferon alfa-2b from Bio-Manguinhos/Fiocruz, Brazil) to those of PEGASYS® (commercially available pegylated interferon alfa-2a from Roche Pharmaceutical). METHODS:This phase I, single-centre, randomized, double-blind crossover trial enrolled 31 healthy male volunteers aged 19 to 35 who were allocated to two stages, either side of a 5-week wash-out period, with each arm lasting 14 consecutive days after subcutaneous administration of 180 ?g of one formulation or the other (study or comparator). The main outcome variable was serum pegylated interferon concentrations in 15 samples collected during the course of the study and tested using an enzyme immunoassay. RESULTS:There were no differences between formulations in terms of magnitude or absorption parameters. Analysis of time parameters revealed that BIP48 remained in the body significantly longer than PEGASYS® (Tmax: 73 vs. 54 h [p =?0.0010]; MRT: 133 vs. 115 h [p =?0.0324]; ke: 0.011 vs. 0.013 h(-1) [p =?0.0153]; t1/2: 192 vs. 108 h [p =?0.0218]). CONCLUSION:BIP48 showed the expected pharmacokinetic profile for a pegylated product with a branched molecular structure. Compared to PEGASYS®, the magnitude absorption was similar, but time parameters were consistent with slower elimination. Further studies should be conducted to evaluate the clinical implications of these findings. A phase II-III repeated-dose clinical trial is ongoing to study these findings in patients with chronic hepatitis C virus infection. TRIAL REGISTRATION:This study is registered on the ClinicalTrials.gov platform (accession number NCT01889849 ). This trial was retrospectively registered in June 2013.

Project description:This study aimed to assess and compare the pharmacokinetic (PK) and pharmacodynamic (PD) properties following a single subcutaneous injection of epoetin alfa (Eporon®) with those of the comparator (Eprex®) in healthy male subjects.A randomized, double-blind, two-sequence, crossover study was conducted. Subjects were randomly assigned to receive a single dose, that is, 4,000 IU, of the test or comparator epoetin alfa. After 4 weeks, all subjects received the alternative formulation. The primary PK parameters, maximum observed concentration (Cmax) and area under the curve extrapolated to infinity (AUCinf), were calculated with the serum erythropoietin (EPO) concentrations from blood samples collected for 144 h after dosing. The reticulocyte, hematocrit, hemoglobin and red blood cell counts were measured up to 312 h as PD markers. The primary PD parameters, maximum observed effect (Emax) and area under the effect curve (AUEC), were obtained from the baseline-corrected reticulocyte count. The serum EPO concentration and the reticulocyte count were used to assess the concentration-response relationship. The tolerability and immunogenicity profiles were assessed together.Forty-two subjects completed the study. The mean EPO concentration-time profiles were comparable between the two formulations. The geometric mean ratios (90% CI) of the Cmax and AUCinf were 0.908 (0.843-0.978) and 1.049 (0.999-1.101), respectively, both of which were within the regulatory range of 0.80-1.25. Additionally, the PD and tolerability profiles were similar between the two formulations. The time-matched serum EPO concentration and PD markers presented a counterclockwise hysteresis, suggesting a time delay between the measured concentration and the response. Both formulations were well tolerated, and production of anti-drug antibodies was not observed.The two epoetin alfa formulations had similar PK, PD and tolerability profiles. Furthermore, both formulations had a similar time-matched serum EPO concentration and erythropoietic response profile. Thus, the two formulations are expected to be used interchangeably in clinical settings.

Project description:Background and objectiveA novel tiotropium bromide monodose capsule dry powder inhaler (DPI) formulation and device have been developed. The formulation was based on a spray-dried matrix that enhances the aerosolizaton properties, allowing a less active tiotropium metered dose (13 µg/capsule) while maintaining the same delivered dose (10 µg/actuation). This study describes the pharmacokinetic bioequivalence to the reference product.MethodsThis randomized, two-stage, crossover, semi-replicate (three-way) study was performed in healthy volunteers. In each study period, subjects received a single dose of two capsules (20 μg delivered dose) of the study medication, separated by a 14-day washout period: tiotropium 10 μg delivered dose (Laboratorios Liconsa, Spain) and Spiriva HandiHaler(®) (Boehringer Ingelheim Pharma GmbH & Co KG, Germany). Blood samples were obtained up to 48 h post-dose to evaluate the comparative bioavailability. Tiotropium was measured in plasma by means of dual stage liquid-liquid extraction followed by the two-dimensional ultra-high performance liquid chromatography sensitive sub-pg/mL bioanalytical method. The main pharmacokinetic parameters were maximum plasma concentration (C max), area under the concentration-time curve (AUC) from time zero hours to the last observed concentration at time t (AUC t ), and AUC from time zero hours to 30 min (AUC0.5). Bioequivalence was accepted if the 90.20 % confidence interval (CI) for the ratio test/reference of the primary pharmacokinetic parameters lay within the acceptance range of 80-125 %. Safety assessment was a secondary endpoint.ResultsA total of 30 subjects were randomized and bioequivalence was demonstrated for all primary pharmacokinetic parameters: C max (CI 87.26-106.60 %), AUC t (CI 101.33-111.64 %), and AUC0.5 (CI 97.95-113.49 %). Both study treatments were well tolerated (four non-serious adverse events [AEs] were reported in four subjects: one AE before any product administration, two AEs after test product administration; and one AE after reference product administration).ConclusionsBoth products containing tiotropium 10 µg delivered-dose DPI were bioequivalent and showed good tolerability and a similar safety profile.

Project description:IntroductionAmbroxol is used in the treatment of acute and chronic respiratory conditions characterized by abnormal mucus secretion and impaired mucus transport and is available in a variety of formulations. This study aimed to compare the steady-state (SS) pharmacokinetic characteristics of extended-release (ER) 75-mg retard capsules with two immediate-release (IR) formulations (60-mg effervescent tablets and 30-mg tablets) over a 24-h period.MethodsAn open-label, randomized, three-period, six-sequence crossover study was conducted in healthy volunteers aged 18-45 years who had a normal body mass index. The test (ER 75-mg retard capsule once daily) and reference treatments (half of IR 60-mg effervescent tablet twice daily or 30-mg IR tablet twice daily) were administered on days 1-5 of each treatment period. Meals were standardized and concomitant therapy was prohibited. Blood samples for pharmacokinetic assessment were collected on day 5 (SS) of each treatment period. The co-primary endpoints were exposure (AUCSS 0-24) and maximum plasma level (Cmax SS).ResultsTwenty-four participants received ambroxol (male n = 13, 54.2%; mean ± standard deviation [SD] age 25.0 ± 6.4 years) and 23 completed the study. ER retard capsules provided similar AUCSS 0-24 compared to IR tablets (geometric means ratio [GMR] 110.7%; 90% confidence interval [CI] 99.8%, 122.7%) and effervescent tablets (GMR 106.9%; 90% CI 100.3%, 114.0%). ER retard capsules provided similar Cmax SS compared to IR tablets (GMR 84.7%, 90% CI 77.0%, 93.3%), and lower Cmax SS compared to effervescent tablets (GMR 80.9%, 90% CI 73.9%, 88.6%). Time to Cmax SS (tmax SS) was longer with ER retard capsules (6.0 h) than with IR tablets (2.0 h) or effervescent tablets (1.0 h).ConclusionsER ambroxol 75-mg retard capsules given once daily showed a similar pharmacokinetic profile to IR ambroxol formulations and therefore can be used instead of these in the treatment of respiratory conditions.

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.
