CLINICAL TRIALS PROFILE FOR VANCOMYCIN

505(b)(2) Clinical Trials for vancomycin

This table shows clinical trials for potential 505(b)(2) applications. See the next table for all clinical trials

Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Dosage	NCT01162733 ↗	Loading Vancomycin Doses in the Emergency Department	Completed	Christiana Care Health Services	N/A	2010-07-01	In 2008, our ED administered an average of 245 doses of vancomycin per month. Currently there is no consistency in the ED practice in regards to vancomycin dosing. In 2009, the IDSA put forth new recommendations for vancomycin dosing in order to achieve therapeutic levels more rapidly. It has been hypothesized that if therapeutic levels are reached more rapidly then patients will in turn have better clinical outcomes and that the development of resistant organisms will be decreased. Methicillin resistant Staphylococcus aureus (MRSA) has emerged as one of the most deadly pathogens that are currently plaguing our patient population. Vancomycin is one of only a few antibiotics that are effective for treating MRSA. It is imperative that the ED physicians consistently and correctly dose vancomycin in order to give the patients the best chance to fight infection while helping to prevent further resistance in this already highly resistant organism. It is believed this study will reveal that the new dosing recommendations by the IDSA will lead to the achievement of therapeutic levels more rapidly. This information will in turn help to convince ED physicians that a change in current clinical practice is warranted and ultimately lead to better clinically outcomes for the patients.
New Dosage	NCT01734694 ↗	Safety and Efficacy of Strategy to Prevent Drug-Induced Nephrotoxicity in High-Risk Patients	Terminated	Henry Ford Health System	Phase 4	2011-10-01	For more than fifty years, vancomycin has been cited as a nephrotoxic agent. Reports of vancomycin induced kidney injury (a.k.a vancomycin induced nephrotoxicity or VIN), have waxed and waned throughout the years for various reasons. Recently, VIN has reemerged as a clinical concern. This may be due to various reasons, including new dosing recommendations as well as an increased prevalence of risk factors associated with vancomycin induced nephrotoxicity. This study aims to evaluate a strategy which attempts to reduce kidney damage from vancomycin use.
OTC	NCT04674839 ↗	The Impact of MS-20 on Gut Microbiota Composition in Adult Individuals	Completed	Microbio Co Ltd	N/A	2019-10-18	MicrSoy-20 (MS-20), a fermented soymilk product, has been approved as an Over the counter (OTC) drug in 2011. The therapeutic effect of MS-20 is to ameliorate symptoms such as fatigue and loss of appetite caused by cancer chemotherapy. Animal study revealed orally administration of MS-20 daily for 4 weeks altered the gut microbiota composition in mice. In addition, MS-20 could activate dendritic cell and improve immunotherapy response rate. Thus, it was hypothesis that MS-20 improves host immune activity thus ameliorate fatigue and increase weight is through alteration the gut microbiota composition. In this study, the ability of MS-20 in modulating gut microbiota and the subset of microbiome to be altered by MS-20 was investigated.

It is not yet known which regimen of antibiotics is most effective in preventing infection in these patients. PURPOSE: Randomized phase III trial to study the effectiveness of piperacillin-tazobactam with or without vancomycin in reducing fever in patients who have leukemia, lymphoma, or Hodgkin's disease.
NCT00034294 ↗	A Study of GT160-246 Versus Vancomycin in Patients With Clostridium Difficile-Associated Diarrhea	Completed	Genzyme, a Sanofi Company	Phase 2	2002-02-01	Approximately 300 patients will be entered into this study taking place throughout the United States, Canada and the United Kingdom. This study aims to determine if an investigational drug is safe and effective for treating the symptoms of C. difficile-associated diarrhea and lowering the risk of repeat episodes of diarrhea. The investigational drug will be evaluated in comparison to current standard antibiotic treatment, so all patients will receive active medication. All study-related care is provided including doctor visits, physical exams, laboratory tests and study medication. Total length of participation is approximately 10 weeks.
