32 Clinical Trials for Various Conditions
A phase 2, multi-center, double-blind, randomized, placebo-controlled study to evaluate the safety, phage kinetics, and efficacy of inhaled AP-PA02 administered in subjects with non-cystic fibrosis bronchiectasis and chronic pulmonary Pseudomonas aeruginosa infection.
The purpose of this trial is to compare the effects of treatment with tobramycin solution for inhalation (TIS) with and without azithromycin in people with cystic fibrosis (CF) age 6 months to 18 years who have early isolation of Pseudomonas aeruginosa (Pa) from a respiratory culture. Specimens of blood and sputum or throat swabs will be taken during the study along with pulmonary function testing. Participants will receive initial treatment with TIS followed additional treatment with TIS if quarterly respiratory cultures are positive for Pa in addition to either azithromycin or placebo for 18 months.
The primary objective of this study is to evaluate the safety and efficacy of a CAT regimen with aztreonam for inhalation solution (AZLI) and tobramycin inhalation solution (TIS) in adult and pediatric subjects with cystic fibrosis (CF) and pulmonary Pseudomonas aeruginosa (PA) infection. Participants will be enrolled in a 28 day TIS run-in phase, and will be eligible for randomization in the comparative phase if they have not received non-study oral antibiotics for a respiratory event, or IV or inhaled antibiotics for any indication between Visits 2 and 3, have not developed a condition requiring hospitalization or other change in clinical status which, in the opinion of the investigator would preclude their ability to continue in the study, and have demonstrated at least 50% TIS compliance. Participants enrolled in the comparative phase will be randomized to receive 3 cycles of treatment, each cycle consisting alternating regimens: AZLI or placebo for 28 days followed by TIS for 28 days.
The goal of this Phase 2b clinical trial is to see if nebulized phage (BX004) can treat chronic Pseudomonas aeruginosa (PsA) lung infection in CF subjects. The primary goal is to see if 8 weeks of twice daily BX004 can reduce the amount of PsA in the sputum compared to placebo (on top of background CF therapy).
This is a Phase 1b/2a study with the primary objective to determine if BX004-A is safe and tolerable. Exploratory objectives include whether BX004-A reduces sputum Pseudomonas aeruginosa (PsA) bacterial load in CF subjects with chronic PsA pulmonary infection.
There is established evidence that adult patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Ceftolozane/Tazobactam is a newly approved broad spectrum intravenous antibiotic, which has potent in vitro activity against multidrug resistant Pseudomonas aeruginosa, the most common pathogen implicated in CF pulmonary exacerbations. This study will determine the pharmacokinetics and tolerability of ceftolozane/tazobactam in 20 adult CF patients admitted for a pulmonary exacerbation at one of 4 participating hospitals in the US. Patients will remain on standard of care IV antibiotics and receive 4-6 doses of ceftolozane/tazobactam 3 grams every 8 hours. Blood will be sampled after the final dose to determine concentrations and pharmacokinetics of ceftolozane and tazobactam. Safety and tolerability will be assessed throughout the 3 day study.
This study will determine the concentrations of the antibiotic meropenem when administered as a 3 hour prolonged infusion in children with cystic fibrosis who are hospitalized with an acute pulmonary exacerbation. Safety and practicality of administering meropenem as a 3 hour infusion will be measured.
Although cystic fibrosis (CF) is the most common, life-threatening autosomal recessive genetic disorder of the white population, there are often delays in diagnosis and hence start of treatment. Advances of the past two decades have made CF screening feasible using routinely collected neonatal blood specimens and measuring an enzyme level followed by CF mutation DNA analysis. Our overall goal of the study is to see if early diagnosis of CF through neonatal screening will be medically beneficial without major risks. ''Medically beneficial'' refers to better nutrition and/or pulmonary status, whereas '' risks'' include laboratory errors, miscommunication or misunderstanding, and adverse psychosocial consequences. Specific aims include assessment of the benefits, risks, costs, quality of life, and cognitive function associated with CF neonatal screening and a better understanding of the epidemiology of CF. A comprehensive, randomized clinical trial emphasizing early diagnosis as the key variable has been underway since 1985. Nutritional status has been assessed using height and weight measurements and biochemical methods. The results have demonstrated significant benefits in the screened (early diagnosis) group. We are now focusing on the effect of early diagnosis of CF on pulmonary outcome. Pulmonary status is measured using chest radiographs, chest scans using high resolution computerized tomography, and pulmonary function tests. Other factors that we are looking at include risk factors for the acquisition of respiratory pathogens such as Pseudomonas aeruginosa, quality of life and cognitive function of children with CF who underwent early versus delayed diagnosis, as well as the cost effectiveness of screening and the costs of diagnosis and treatment of CF throughout childhood. If the questions underlying this study are answered favorably, it is likely that neonatal screening using a combination of enzyme level (immunoreactive trypsinogen) and DNA test will become the routine method for identifying new cases of CF not only in the State of Wisconsin, but throughout the country.
Phase 1b/2a, double-blind, randomized, placebo-controlled, single and multiple ascending dose study to evaluate the safety, tolerability and phage recovery profile of AP-PA02 multi-bacteriophage therapeutic candidate administered by inhalation in subjects with cystic fibrosis and chronic pulmonary Pseudomonas aeruginosa (PA) infection.
The purpose of this study is to evaluate the safety and efficacy of 2 dose combinations of fosfomycin/tobramycin for inhalation (FTI), following a 28-day course of Aztreonam for Inhalation (AZLI) in patients with cystic fibrosis and Pseudomonas aeruginosa lung infection.
The primary objective of this program is to provide expanded access to aztreonam lysine for inhalation (AZLI) 75 mg prior to its commercial availability to patients with cystic fibrosis (CF) and chronic P. aeruginosa airway infection who have limited treatment options and are at risk for disease progression.
The primary objective of this study is to evaluate the safety and efficacy of a 14-day course versus a 28-day course of aztreonam for inhalation solution (AZLI) in pediatric participants with new onset Pseudomonas aeruginosa respiratory tract infection or colonization.
This is a study to determine the safety and tolerability of 28 days of daily dosing of two doses (280 mg and 560 mg) of Arikayce™ versus placebo in patients who have bronchiectasis and chronic infection due to Pseudomonas infection.

Researchers want to find out if a drug called Cipro® XR (ciprofloxacin extended-release) can help people with a complicated urinary tract infection caused by a kind of bacteria called Pseudomonas aeruginosa. The study doctor will give Cipro XR to some people to see if it is safe and works to treat complicated urinary tract infections caused by Pseudomonas aeruginosa. The study doctor will also gather information about using Cipro XR to treat complicated urinary tract infections caused by other bacteria. About 500 people with complicated urinary tract infections who are 18 years old and older will join this study. Cipro XR is approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated urinary tract infections and acute uncomplicated pyelonephritis (inflammation of the kidney). The dose of Cipro XR used in this study (1000 mg a day for 7 to 14 days), has been shown to be safe and effective. This study is being done to gather more information on using this dose of Cipro XR for complicated urinary tract infections caused by Pseudomonas aeruginosa, as well as by other bacteria.
Some bacteria that cause disease can produce toxic substances that may worsen the disease. Pseudomonas aeruginosa is a bacteria that can produce a variety of toxins and is of special interest for patients with cystic fibrosis and repeated long term lung infections. The goal of this study is to determine whether specific toxins produced by Pseudomonas aeruginosa may be important in the disease process of chronic lung infections of patients with cystic fibrosis. This study will attempt to measure bacterial production of toxins in blood and sputum and immune system response to toxins in the blood....
The Gram-negative bloodstream infection Oral Antibiotic Therapy trial (The GOAT Trial) is a multi-center, randomized clinical trial that hypothesizes that early transition to oral antibiotic therapy for the treatment of Gram-Negative BloodStream Infection (GN-BSI) is as effective but safer than remaining on intravenous (IV) antibiotic therapy for the duration of treatment.

This is an open-label, multi-center study in pediatric patients age 3 months to less than 18 years with cystic fibrosis (CF) and newly detected Pseudomonas aeruginosa (PA) pulmonary colonization/infection. All eligible participants will be treated with a 28-day course of Aztreonam for Inhalation Solution (AZLI) 75 mg 3 times daily. After completion of study drug, subjects will be followed up through Day 196 for safety and recurrence of PA. The primary objective is to evaluate the proportion of participants with PA-negative cultures at all time points during a 6-month monitoring period (through Day 196) after cessation of AZLI treatment. Microbiological cultures will be obtained at Baseline, Day 28 (end of AZLI treatment), Day 56 (1 month after completing AZLI treatment), Day 112 (3 months after completing AZLI treatment), and Day 196 (6 months after completing AZLI treatment).
This is multicenter placebo-controlled study evaluating the safety and efficacy of AI at two dosage levels compared to placebo in CF patients with P. aeruginosa lung infection.
Carbapenems are a class of antibiotic agents which kill a broad spectrum of bacteria. Infections due to gram-negative bacteria which have acquired resistance to carbapenems are increasing, especially with Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa . The optimal treatment of such infections is not known. Antibiotics like polymyxin, tigecycline and rifampin are used alone or in combination with other antibiotics. The outcome of using these new and old drugs is not well studied. This observational study aims to study the clinical and microbiological outcomes of these infections and treatment at our institution.
The purpose of this study was to assess the comparative safety and effectiveness of aztreonam for inhalation solution versus tobramycin inhalation solution in adult and pediatric patients with cystic fibrosis (CF) and pulmonary Pseudomonas aeruginosa (PA) infection.
This is a randomized, open label, comparative Phase II trial being conducted to determine whether fecal microbiota transplant using Penn Microbiome Therapy (PMT) products helps standard therapy eradicate antibiotic-resistant bacteria.
This study is specifically designed to provide observational data which can be used to help in the design of future randomized clinical trials on both therapeutics and diagnostics for MDRO infections. To this end, clinical and epidemiological data will be collected on patients who have MDRO isolated from clinical cultures during hospitalization, as well as descriptions of the outcomes of patients treated with various antimicrobial regimens. Molecular and microbiological characterization will also be performed on MDRO isolates. These data will include a detailed clinical and epidemiological description of patients including identifying potential barriers to enrollment in future trials. In addition, data will be collected on species, strain type, and mechanism of drug resistance of the causative organism. Knowing the molecular characteristics will further inform future trial design as not all diagnostics detect and not all therapeutics are active against the same mechanisms of resistance.
This is a prospective, case-control clinical trial using inhaled Aztreonam (AZLI) in pediatric patients with a tracheostomy tube colonized with Pseudomonas aeruginosa. The aim of the study is to see if AZLI being taken in a one month on / one month off cycle over the course of a year can decrease the need for systemic antibiotics and/or hospitalizations.
The objective is to determine the safety, tolerability and pharmacokinetics (PK) of 2 single doses of ZTI-01 (1g and 8g infused over 1-hr) and a single dose of the Reference Label Drug, Monurol® (oral sachet, 3g). Subjects will be randomized to a treatment sequence prior to dosing on Day 1 of Period 1 prior to study screening.
This study assessed the long term safety data for the use of tobramycin inhalation powder in patients suffering from cystic fibrosis who have a chronic pulmonary infection with Pseudomonas aeruginosa.
This study will examine 1) the role of hereditary factors in cystic fibrosis; i.e., the relationship of the disease to specific gene variations, and 2) the role of bacterial products involved in lung infections substances produced by bacteria may worsen the disease. Patients with cystic fibrosis who are being followed by the Medical College of Wisconsin or the University of Wisconsin-Madison are eligible for this study. Participants will have blood tests, pulmonary function tests, a sputum culture, and buccal swabbing (cotton swabbing of the inside of the cheek to collect cells for DNA study). In addition, their medical records will be reviewed for a history of lung infections and the results of various tests, including pulmonary function studies, chest X-rays and bacterial cultures. Blood samples collected previously at the Medical College of Wisconsin or the University of Wisconsin-Madison will also be analyzed for antibodies to bacteria. Although this is a one-time study, participants may be asked to return for repeated tests. ...
