An evaluation of the safety and efficacy of bimatoprost for eyelash growth in pediatric subjects.

ABSTRACT: PURPOSE:Evaluate the safety and effectiveness of bimatoprost 0.03% for treatment of eyelash hypotrichosis in a pediatric population. PATIENTS AND METHODS:This multicenter, randomized, double-masked, parallel-group study was conducted at seven sites in the US and Brazil. Subjects with eyelash hypotrichosis caused by chemotherapy or alopecia areata (aged 5-17 years) or healthy adolescents aged 15-17 years were enrolled (N=71). Subjects applied bimatoprost 0.03% or vehicle to upper eyelid margins once nightly for 4 months and were followed for 1 month post-treatment. Eyelash prominence was assessed using the validated 4-grade Global Eyelash Assessment scale with photonumeric guide. Changes in eyelash length, thickness, and darkness were measured by digital image analysis. Safety was assessed by adverse events and ophthalmic observations. RESULTS:Eyelash prominence improved in a significantly greater proportion of subjects treated with bimatoprost compared with vehicle at month 4 (70.8% versus 26.1%; P<0.001). This benefit was sustained at month 5 post-treatment assessment. Digital image analysis measures were significantly improved with bimatoprost. Significant treatment benefits with bimatoprost versus vehicle were evident among the healthy adolescents but not in the postchemotherapy or alopecia areata subgroups. The safety profile of bimatoprost was consistent with previous studies in adults. CONCLUSION:Bimatoprost was safe and well tolerated in pediatric subjects with eyelash hypotrichosis. In this study with limited sample size, subgroup analyses showed that treatment was effective in healthy adolescents with no concurrent contributing medical condition, but not in those with eyelash hypotrichosis due to chemotherapy or alopecia areata.

Project description:BackgroundBimatoprost 0.03% has enhanced eyelash prominence in clinical trials enrolling mostly Caucasian subjects. The studies described in this report evaluated the efficacy and safety of bimatoprost in Japanese subjects with idiopathic and chemotherapy-induced eyelash hypotrichosis.MethodsIn two multicenter, double-masked, randomized, parallel-group studies (study 1: n=173 [idiopathic]; study 2: n=36 [chemotherapy-induced]), subjects received bimatoprost 0.03% or vehicle applied once daily to the upper eyelid margins. The primary efficacy measure was eyelash prominence measured by Global Eyelash Assessment (GEA) scores. Additional measures were eyelash length, thickness, and darkness, assessed by digital image analysis, and patient satisfaction (Eyelash Satisfaction Questionnaire-9). Safety assessments included adverse-event monitoring and ophthalmic examinations.ResultsSignificantly more bimatoprost-treated subjects had at least a one-grade improvement in GEA score from baseline to month 4 compared with vehicle in study 1 (77.3 vs 17.6%; P<0.001) and study 2 (88.9 vs 27.8%; P<0.001). Bimatoprost-treated subjects had significantly greater increases in eyelash length, thickness, and darkness at the primary time point (month 4 in both studies; all P<0.001, study 1; P≤0.04, study 2). The bimatoprost group showed greater subject satisfaction in both studies. The incidence of adverse events was similar in the two groups. Ophthalmic examination showed slightly greater mean reductions in intraocular pressure (IOP) with bimatoprost than with vehicle, and the reductions were within the normal range for daily IOP fluctuations.ConclusionBimatoprost 0.03% was shown to be effective and safe in these studies of Japanese subjects with eyelash hypotrichosis.Level of evidence iThis journal requires that authors assign a level of evidence to each article.

Project description:OBJECTIVES:The primary objective of this study was to investigate the pharmacokinetic profile of gadoterate meglumine in pediatric patients younger than 2 years; the secondary objectives were to document its efficacy and safety. MATERIAL AND METHODS:This was a Phase IV open-label, prospective study conducted in 9 centers (4 countries). Forty-five patients younger than 2 years with normal estimated glomerular filtration rate and scheduled to undergo routine gadolinium-enhanced magnetic resonance imaging (MRI) of any organ were included and received a single intravenous injection of gadoterate meglumine (0.1 mmol/kg). To perform the population pharmacokinetics analysis, 3 blood samples per subject were drawn during 3 time windows at time points allocated by randomization. RESULTS:Gadoterate meglumine concentrations were best fitted using a 2-compartmental model with linear elimination from central compartment. The median total clearance adjusted to body weight was estimated at 0.06 L/h per kg and increased with estimated glomerular filtration rate according to a power model. The median volume of distribution at steady state (Vss) adjusted to body weight was estimated at 0.047 L/kg. Estimated median terminal half-life (t1/2?) was 1.35 h, and the median systemic exposure (area under the curve) was 1591 ?mol h/L. Efficacy was assessed by comparing precontrast +postcontrast images to precontrast images in a subset of 28 subjects who underwent an MRI examination of brain, spine, and associated tissues. A total of 28 lesions were identified and analyzed in 15 subjects with precontrast images versus 30 lesions in 16 subjects with precontrast + postcontrast images. Lesion visualization was improved with a mean (SD) increase in scores at subject level of 0.7 (1.0) for lesion border delineation, 0.9 (1.6) for internal morphology, and 3.1 (3.2) for contrast enhancement. Twenty-six adverse events occurred postinjection in 13 subjects (28.9%), including 3 serious reported in 1 subject (2.2%). One subject (2.2%) experienced 1 rash of moderate intensity considered as related to gadoterate meglumine. CONCLUSIONS:The pharmacokinetic profile of gadoterate meglumine after a single intravenous injection of 0.1 mmol/kg was appropriately described in newborns and infants younger than 2 years, for whom no dose adjustment is required. The improved efficacy of gadoterate meglumine for contrast-enhanced MRI examination of brain, spine, and associated tissues, as well as its good safety profile, was also demonstrated in this population.

Project description:BackgroundMivacurium is the shortest acting nondepolarizing muscle relaxant currently available; however, the effect of different dosages and injection times of intravenous mivacurium administration in children of different ages has rarely been reported. This study was aimed to evaluate the muscle relaxant effects and safety of different mivacurium dosages administered over different injection times in pediatric patients.MethodsSix hundred forty cases of pediatric patients, aged 2 m-14 years, ASA I or II, were divided into four groups (Groups A, B, C, D) according to the age class (2-12 m, 13-35 m, 3-6 years and 7-14 years) respectively, also each group were divided into four subgroups by induction dose (0.15, 0.2 mg/kg in 2-12 m age class; 0.2, 0.25 mg/kg in other three age classes), and mivacurium injection time (20 s, 40 s), totally 16 subgroups. Neuromuscular transmission was monitored with supramaximal train-of-four stimulation of the ulnar nerve. Radial artery blood (1 ml) was sampled to quantify plasma histamine concentrations before and 1, 4, and 7 min after mivacurium injection (P0, P1, P2 and P3).ResultsFive hundred sixty-two cases completed the study. There were no demographic differences within the four groups. The onset time of 0.2 mg/kg groups in 2-12 m aged patients were shorter than those of 0.15 mg/kg groups (189 ± 64 s vs. 220 ± 73 s, 181 ± 60 s vs. 213 ± 71 s, P <0.05), and the recovery times were no statistical differences. The T1 25% recovery time of 0.2 mg/kg in 3-6 years aged patients was shorter than that of 0.25 mg/kg group (693 ± 188 s vs. 800 ± 206 s, P <0.05). The onset and recovery times of mivacurium were not different in 13-35 m and 7-14 years aged patients. The plasma concentrations of histamine at P0, P1, P2 and P3 were not different within four groups.ConclusionsThe induction dose and injection time of mivacurium had mostly insignificant effects on onset and recovery times. The main exception to this was that in 2-12 m aged patients, increasing the dose of mivacurium from 0.15 to 0.2 mg/kg accelerated the onset time by about 30 s. Mivacurium produced no significant release of histamine in any age group at the doses studied.Trial registrationClinicalTrials.gov Identifier- NCT02117401 , July 14, 2014.
