Filter by:The purpose of this study is to test the feasibility of using thermal images to diagnose bacterial pneumonia instead of a chest x-ray in the future. More specifically, the objectives of this study are: 1) to determine if thermal imaging, using a commercial thermal camera can detect areas of heat emitted from the chest in similar locations to where a chest X-ray shows focal consolidation consistent with bacterial pneumonia; 2) to evaluate whether changes in heat emitted from the chest changes over time if it is possible to obtain serial images of the chest.
This field study is designed such that it may be implemented for any individual who has been administered raxibacumab for treatment of anthrax or for post-exposure prophylaxis including sporadic cases, small anthrax incidents and/or a mass event. This study is designed to describe the clinical effectiveness (including course of illness and survival), safety profile, and raxibacumab pharmacokinetics (PK) from patients who are treated with raxibacumab as part of their clinical care following exposure to B. anthracis. Study data and samples for PK and other investigational research will be collected prospectively to the extent possible at pre-specified time points. However, because of the logistical complexities that would likely accompany a mass anthrax event, most data in this study is anticipated to be collected retrospectively. During such a mass anthrax event scavenged blood samples will be utilized where possible to maximize sample analyses for PK and other investigational parameters. Therefore, both retrospective and prospective data collection are allowed in this protocol in order to maximize the amount of information obtained in subjects who have been administered raxibacumab. This field study will be the first opportunity to collect data on B. anthracis-exposed patients treated with raxibacumab, to better understand the clinical benefit and safety of the drug and to further inform patient care and treatment choices for management of anthrax
This study will be conducted in three parts (Part 1, Part 2 and Part 3). Part 1 of this study will evaluate the relative bioavailability of a single dose of GSK2140944 tablet formulation compared to the reference capsule formulation under fasted conditions. The effect of food on the pharmacokinetics (PK) of a single dose of the tablet formulation will also be assessed. Part 2 will evaluate the effect of repeat doses of itraconazole on the pharmacokinetics of GSK2140944 following a single dose. A decision will be made whether to use the current capsule formulation or the new tablet formulation in Part 2 based upon the safety and PK data obtained from Part 1. Part 3 is conditionally based upon progression of the tablet formulation from Part 1 and will evaluate the effect of food on the safety, tolerability, and pharmacokinetics of the tablet formulation following multiple doses in elderly healthy subjects.
GSK2140944 belongs to a novel structural class of antibiotics - Bacterial Type II Topoisomerase Inhibitors (BTI). This is a Phase II, randomized, two-part, multicenter study designed to select the optimal dose by further characterizing the safety, tolerability and PK of GSK 2140944 and by evaluating efficacy in subjects requiring in-patient medical care to treat their suspected or confirmed Gram-positive acute bacterial skin and skin structure infections (ABSSSI). The selected dose will be used in future studies.
This study is being conducted to confirm that GSK1322322 has no negative impact on hormone levels and contraceptive efficacy when co-administered with a frequently prescribed oral contraceptive thereby to facilitate the use of GSK1322322 in women of child-bearing potential receiving oral contraceptive (OC) pre-infection. This study is designed to investigate steady-state plasma ethinyl estradiol (EE) and norethindrone (NE) pharmacokinetic (PK) following administration of Ortho-Novum (EE/NE) 1 tablet every 24 hours (q24h) fed with and without GSK1322322 1500 milligram (mg) q12h fed. Each subject will participate in the study for approximately 12 weeks: a 30 day screening period, 4-week run-in period, three 7 day treatment periods, and a 3-5 day follow-up period. The study is planned to enroll approximately 24 subjects (18 active/6 placebo).
Antimicrobial penetration can be assessed through evaluation of antimicrobial concentrations in various lung compartments, including bronchial mucosal tissue, epithelial lining fluid (ELF), and alveolar macrophages (AM). Antimicrobial concentrations determined in ELF and alveolar macrophages represent an ideal estimate of concentrations at the site of infection and can be accessed via bronchoalveolar lavage (BAL). However sampling of antimicrobial concentrations via BAL is not routine in clinical practice due to its complex methodology and poor patient tolerability. This study will evaluate intrapulmonary and plasma pharmacokinetics of GSK2140944 after single IV dose in adult healthy volunteers. This is a Phase I, open-label study to evaluate plasma and pulmonary pharmacokinetics following intravenous administration of GSK2140944 in healthy adult participants. Part A will evaluate the single dose PK profiles. Part B is optional and will only be conducted if necessary. Each part will consist of a maximum of 6 cohorts. In Part A, only 4 of the 6 cohorts will be dosed initially; cohorts 5 and 6 are optional and will only be dosed if additional time-points are necessary to adequately model the pulmonary pharmacokinetic profile.
The primary objectives of this study are to assess the safety, tolerability and pharmacokinetics of GSK1322322 following intravenous (IV) and oral administration. GSK1322322 shows broad spectrum antibacterial activity against pathogens involved in respiratory tract infections as well as methicillin-resistant S. Aureus (MRSA). This study consists of three parts (Part A, Part B and Part C). The results from Part A of this study will enable use of large-scale, commercial tablets produced for administration to patients in pivotal clinical trials of GSK1322322. The results from Parts B and C will support enrolment of Japanese subjects in future clinical studies. Additionally, the results will support the dose selection for further clinical development of GSK1322322 in hospitalized patients with severe bacterial infections in Japan and other Asian populations. In Part A, subjects will undergo screening, 4 treatment periods receiving single dose of each of: 1500 mg Initial, fit-for-purpose tablet (product code AP), 1500 mg Over granulated tablet (product code AR), and the 1500 mg and 2000 mg of intended commercial tablets (product code AU). In Part B of the study subjects will undergo screening, and be randomized to receive 3 doses of GSK1322322 oral cohort (100 mg, 1500 mg and 2000 mg) or IV cohort (600 mg, 900 mg and 1200 mg) each in 3 treatment periods. Part C will be a single-blind, placebo-controlled, repeat dose study of GSK1322322 in healthy Japanese male subjects. GSK1322322 will be administered (fasted) via IV for 4 days BID, followed by administration of GSK1322322 orally (fed) for 6 days BID. A follow-up evaluation will be conducted 7-10 days following last dose of for each subjects in each Part of the study. Approximately 12 subjects will be enrolled in each part of the study such that approximately 8, 6, and 9 subjects complete dosing and critical assessments in part A,B, and C respectively.
This is a randomized, partially-blinded, placebo and moxifloxacin-controlled, single dose, 4-period, balanced crossover study. The primary objective of this study is to separately assess the effects of a therapeutic and supratherapeutic dose of GSK1322322 on the cardiac conduction (corrected QT interval [QTc]) compared with placebo in eligible healthy male and female subjects. Avelox (moxifloxacin hydrochloride) will be used as an open-label positive control in order to validate the sensitivity of the study in detecting QTc change. Approximately 56 healthy subjects will participate in the study for approximately 9 weeks i.e. 30 day Screening period, 4-week Treatment period, and a 7-10 day Follow-up period. There will be 4 treatment periods separated by at least 1 week. Subjects will be admitted to the clinical unit on Day -1 of each dosing period. Each subject will receive each of the four treatment sequences (GSK1322322 1200 milligram [mg] intravenous [IV] over 60 minutes x 1 dose, GSK1322322 3000 mg IV over 60 minutes x 1 dose, GSK1322322 Placebo IV over 60 minutes x 1 dose, moxifloxacin 400 mg administered orally x 1 dose) on Day 1 of each Treatment period in a randomized fashion. Twelve-lead electrocardiogram (ECG), continuous Holter monitoring, laboratory tests, vital sign measurements, and serial pharmacokinetic samples will be collected for up to 24 hours following each treatment. If no clinically significant abnormalities are noted, subjects will be discharged from the clinical research unit after the completion of all assessments on Day 2 in each period and return approximately one week later for the next dosing period. Each individual subject will follow the same dosing schedule at every period. A Follow-up visit will be conducted 7-10 days after administration of the last dose of study medication in treatment period 4.
This is a phase 1, non-randomized, open label, single-dose, two-period, cross-over study. This study will utilize 14C radiolabeled GSK1322322 to investigate the recovery, excretion, and pharmacokinetics of GSK1322322 in 6 healthy adult male subjects through the sampling of blood, urine, and feces. Each subject will participate in the study for approximately 7 to 8 weeks i.e., 30 day screening period, two dosing periods (approximately 8 days each) and a follow up visit. The subjects will be admitted to the clinical unit on Day 1 of the first treatment period and remain in the unit for up to approximately 16 days through the end of the second treatment period. On Day 1 of Period 1, each subject will receive 14C radiolabeled GSK1322322 as a single therapeutic intravenous (IV) dose (1000 milligrams [mg]). When the total radioactivity is <1% of the administered dose in all subjects, Period 2 dosing will begin (approximately 8 days after the IV dose). On Day 1 of Period 2, each subject will receive single therapeutic oral solution dose (1200 mg). Blood, urine, bile and fecal samples will be collected during both the periods. The subject may be discharged from the unit as early as Day 8 of Period 2. Subjects will visit the study unit for the follow-up visit 7 to 10 days following discharge from the unit.
This study is an open-label, randomized, single dose, four period, balanced crossover study to assess in eligible healthy male or female subjects.
