Active clinical trials for "Bacterial Infections"

To assess the relative bioavailability of two different batches of Frademicina® drug product, containing 500 mg lincomycin hydrocloride, manufactured by Pfizer Laboratories Ltd. The formulations' comparative bioavailability after oral administration will be assessed based on the statistical comparisons of the relevant pharmacokinetic parameters, obtained from the drug concentrations in the blood. The lincomycin hydrocloride concentration will be measured by a proper and validated analytical method.

The FDA has asked Pfizer to assess the risk of linezolid on QT interval (obtained from ECG readings) which could predispose patients to ventricular arrhythmias. This study is conducted to satisfy this requirement.

A phase one study to characterize the pharmacokinetics of dalbavancin in pediatric patients aged 3 months to 11 years (inclusive) following the intravenous administration of a single dose of dalbavancin.

Debio 1450-103 is a trial to study the pharmacokinetics (PK) of an experimental drug called Debio 1450 in healthy adult volunteers. Originally, Part A was registered separately (in NCT02214355). The registrations have been revised so all parts of this single trial (Parts A-C) are now included in this single registration (NCT02214433). The primary purpose of each part is provided below: 10 volunteers participate in PART A to assess the PK of a single oral dose of Debio 1450 (tablet formulation) under varying gastric conditions 40 volunteers participate in PART B to assess the safety, tolerability and PK of multiple ascending doses of Debio 1450, administered sequentially IV and orally, once or twice daily. An additional 10 volunteers participate in PART C which is designed to assess the absolute bioavailability of various formulations of Debio 1450 under varying gastric conditions The dose administered during Part A is based on the safety, tolerability and PK data from study Debio 1450-102 [NCT02162199], a single ascending dose (SAD) study, in which single oral doses up to 800 mg/day are being investigated. Doses are adjusted during Parts B and C based on the available safety and PK data from preceding cohorts.

The sponsor is trying to develop a medicine for infections that are not cured by regular antibiotics. They have an experimental drug called Debio 1450 that may work. They need about 48 healthy adults to volunteer for this study. This study looks at what the body does to the drug. It measures how the amount of drug in blood and urine changes over time. From the screening visit through the follow-up visit may be up to 40 days. Volunteers go to the clinic in Baltimore for a screening visit. The study doctor chooses qualified volunteers to participate or serve as alternates. Alternates might not actually complete the study procedures. The study doctor divides participants into groups of eight. Six receive Debio 1450 and 2 receive Placebo. The drug each participant receives is decided by chance - like flipping a coin. Eligible volunteers check into the clinic for testing and those chosen to participate remain for a 5-day/ 4-night stay. The clinic serves standard meals, except when fasting is required. Participants must stay at the clinic for the length of the study. This study is a "dose escalation" study. That means that if no safety concerns come up a new group starts. Each new group of eight participants receives more capsules. The study product is contained in capsules. Each capsule contains either placebo or 40 mg Debio 1450. After fasting overnight, the first two participants in the group receive their capsules. One gets Debio 1450 and one gets Placebo. If these participants tolerate side effects for 24 hours, the remaining six participants receive their assigned capsules. The plan is to increase the dose for the next group. The study doctor reviews the measurements collected from each group after three days. He may decide to repeat, increase, or lower the dose or even stop the study. The most any participant receives is 800 mg in 20 capsules.

This first time in human (FTIH) study will be the first administration of GSK1322322 as an intravenous formulation and will investigate safety, tolerability, and pharmacokinetics in healthy subjects. One cohort of subjects will undergo bronchoalveolar lavage (BAL) for determination of GSK1322322 concentrations in lung with simultaneous comparison to plasma concentrations to evaluate drug penetration in the lung. The study will evaluate the absolute bioavailability of an oral tablet formulation as compared to the IV formulation.In addition, Amendment 01 will enable the investigation of an improved IV formulation (GSK1322322J mesylate salt) in an additional repeat dosing cohort and the supra-therapeutic cohort.

This study will examine the phototoxicity, a reaction to light that is like exaggerated sunburn, which occurs in people who take medications such as voriconazole, a medication used to fight fungus. Sunscreens might protect the skin from the reaction. Although phototoxicity from voriconazole is not completely understood, it may be related to how that medication is metabolized in the liver by enzymes called cytochrome P450 enzymes-and mainly by one known as 2C19. A way to evaluate phototoxicity is through microarrays, which measure how much each gene is expressed in cells from tissues such as skin. Patients ages 8 and older who are scheduled to begin taking or who currently take voriconazole may be eligible for this study. Also, patients ages 18 to 45 in good health who have skin tone known as Type 2, which usually burns and tans only slightly following sun exposure, may be eligible. All patients will visit the Dermatology Clinic. They will complete two questionnaires, on medical history and medications, as well as the skin response to sunlight, and donate about 3 teaspoons of blood. Patients who are scheduled to take voriconazole will visit the clinic four times, that is, two visits 2 consecutive days before beginning the medication and two visits on 2 consecutive days after taking it for at least 7 days. Each visit will take 1 to 2 hours. Patients about to take voriconazole will have a blood test and undergo a physical exam of the skin test site, on the buttocks. Researchers will take photographs of the specific site and do tests to measure skin reaction to ultraviolet (UV) light. UV light will be shined on 15 small areas of the skin, each 1 x 1 centimeters. After 24 hours, any redness that occurs on the skin will be checked. Afterward, patients will begin taking voriconazole according to directions by the researchers. At 10 or more days later, patients will visit the clinic. Sunscreen will be applied and 1 hour later after administration of voriconazole, a blood sample will be drawn to check the level of medication. Then UV light will be shined on 23 areas of skin 1 x 1 centimeters. More photographs will be taken of test sites to record changes in skin redness. On the next day, the skin response will be evaluated. Participants in the control group will be asked to avoid UV radiation by wearing hats and clothing, and using sunscreen. They will be given the doxycycline, an antibiotic, and undergo procedures with UV light shined on small areas of the skin, on the buttocks. Control participants will have 7 study days, with visits lasting from 1 to 3 hours and probably not exceeding 8 hours. They will have two shave biopsies on Study Day 2 and on Study Day 7 to determine how the skin has responded to UV light exposures. ...

The purpose of this study is to evaluate the pharmacokinetics of a single dose of daptomycin in patients aged 2-17 years old who have a suspected or proven gram-positive infection for which they are receiving standard antibiotic therapy. The tolerability of a single dose of daptomycin in these patients will also be assessed.

The investigators will performed a large-scale multi center trial to compare the efficacy of a high-dose dual therapy (HDDT) with that of standard therapies in treatment-naive (n = 300) patients with Hp infection. Consecutive symptomatic patients will be recruited in Israel and Spain when tested positive to Hp with serology and 13C urea breath test (13C-UBT) due to symptoms. Patients with gastric cancer, MALT lymphoma, and younger than 18 or older than 80 years old will be excluded. All patients will be naive to eradication therapy and will be randomized into one of three groups: Group 1: Nexium 40 mg and amoxicillin 1.5 gr twice daily for 14 days Group 2: Nexium 40 mg and doxycycline 200 mg twice a day Group 3: Triple therapy of Nexium 20 mg, clarythromycin 500 mg, and amoxicillin 1gr twice a day for 10 days (regular accepted treatment). All treatments will be stopped for a month and then 13CUBT will be repeated. The primary aim of the study is to assess eradication success, intentioned to treat and per protocol in the three treatment regimens. The secondary aim of the study is to assess the safety of high dose amoxicillin and doxycycline.

This is a randomized, controlled multicenter clinical trial. The purpose of this study is to compare the continuous infusion of vancomycin with intermittent infusion regarding the effectiveness to reach the target serum level and the relationship between infusion type and nephrotoxicity in critically ill patients.
