15 Clinical Trials for Various Conditions
Multi-center, randomized, placebo controlled, partially blinded trial comparing the safety and efficacy of fecal microbiota transplantation versus placebo both delivered by rectal enema in subjects 18 years of age or older with recurrent Clostridium difficile Associated Disease (CDAD). 162 male or female subjects will be enrolled in the study. Enrolled subjects will be randomized at each site to receive either FMT by enema or placebo by enema in a 2:1 ratio. Study duration is 3 years, subject participation duration is approximately 1 year. The primary study objectives are: 1) to evaluate the safety of FMT(s) delivered by enema vs. placebo delivered by enema and 2) to determine efficacy of FMT delivered by enema vs. placebo delivered by enema.
The study will evaluate if administration of probiotic Culturelle (Lactobacillus Rhamnosus GG) along with antibiotics can help decrease the occurrence of diarrhea caused by antibiotics as well as Clostridium difficile Diarrhea.
The purpose of the study is to establish the clinical disease outcomes and features of CDAD associated with variant tcdC genotypes. Two hypotheses are to be tested in this study: 1. Severe CDAD and tcdC truncation: Severe CDAD (defined by death and/or colectomy or secondary endpoints) is associated with severe truncations (\> 6 amino acid residues) in TcdC, a negative regulator of toxin A/B production. 2. Disease in low risk populations (patients never exposed to health care facilities and/or patients who never received antibiotics) of any severity is attributable to strains of C. difficile with severe tcdC truncation.
The primary objective of the study is to demonstrate non-inferiority of nitazoxanide compared to vancomycin in resolving symptoms of Clostridium difficile-associated disease (CDAD).
Patients with Clostridium difficile associated disease who fulfill the eligibility criteria will be approached to participate. All study patients must receive standard of care treatment for Clostridium difficile associated disease. Enrolled patients will be randomized to receive a single intravenous solution of a human monoclonal antibody (huMab) to C. difficile toxin A (GS-CDA1) combined with a human monoclonal antibody to C. difficile toxin B (MDX-1388) or 0.9% sodium chloride as placebo in a 1:1 treatment allocation. Patients will be evaluated for safety and clinical outcomes through day 84 +/- 10 days. Occurrence of adverse events, use of concomitant medications, and stool output will be assessed at scheduled phone contacts and study visits. Some patients enrolled will have a subsequent visit on day 168 ± 14 days.
This study will investigate a Clostridium difficile vaccine in adults 50 years of age and older. In half the adults, all 3 doses given are the Clostridium difficile vaccine, and in half the adults, 2 of the 3 doses are the Clostridium difficile vaccine with the other dose containing no active ingredients. The study will look at the subjects' immune response to the vaccine and assess the safety and tolerability of a 2-dose regimen of Clostridium difficile vaccine compared to a 3-dose regimen of Clostridium difficile vaccine.
This study will investigate a Clostridium difficile vaccine in healthy adults 65 to 85 years of age, who will each receive 3 doses of vaccine. The study will assess the lot consistency, safety, and tolerability of the vaccine, and also look at the subjects' immune response to the vaccine.
This study will investigate a Clostridium difficile vaccine in healthy adults aged 65-85 years. Each subject will initially receive 3 doses of vaccine on 1 of 2 vaccination schedules. The study will assess the safety and tolerability of the vaccine as well as the subjects' immune response to the vaccine. One year after the third dose subjects that did not receive placebo will be randomized to receive a fourth dose. Subjects will be followed for up to 4 years after their third vaccination.
This study will investigate a Clostridium difficile vaccine in healthy adults aged 50 to 85 years, who will each receive 3 doses of vaccine. The study will assess the safety and tolerability of the vaccine, and also look at the subjects' immune response to the vaccine.
This is a first-in-human study (phase 1) of a 3-dose vaccination regimen with one of three dose levels of C difficile vaccine with or without adjuvant in healthy adults aged 50 to 85 years. The main goal of the study is to determine how safe and well-tolerated the vaccine is. In addition, the study aims to assess the immune response to the C difficile vaccine.
This study will assess the safety and efficacy of multiple daily dosing of oral LFF571 in patients who have moderate Clostridium difficile infections.
Approximately 65 patients will be entered into this study taking place in North America. The aim of this study is to evaluate the safety, efficacy and absorption of an investigational drug in patients with C. difficile-associated diarrhea (CDAD). All study related care is provided including doctor visits, physical exams, laboratory tests and study medication. Total length of participation is 6 weeks.
An antibody is a substance your body makes to fight off infection. This study will explore the safety and antibody response of a vaccine to prevent severe diarrhea caused by a germ called Clostridoides difficile (C. diff). Three new formulations of the C. diff vaccine will be used in this study, in addition to a C. diff vaccine formulation that has been studied in previous clinical trials. The purpose of this study is to understand if giving the new C. diff vaccine formulations helps people make as many antibodies as giving the previously studied C. diff vaccine formulation. The study is divided into 2 phases. Phase 1 will evaluate 3 new formulations of the C. diff vaccine and 2 dosing schedules spread out over 2 months or 6 months. The Phase 1 portion of the study is seeking participants: * who are healthy adults of 65 to 84 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. All participants in Phase 1 will receive study injections with active vaccine or placebo at each vaccination visit, depending on the vaccine group to which they are assigned. A placebo does not contain any active ingredients. Participants in Phase 1 will attend at least 9 study visits and will take part in the study for approximately 18 months. Based on the results of Phase 1, 1 or 2 of the new C. diff vaccine formulations will be chosen for further study in Phase 2. Phase 2 will evaluate the safety and effects of the new C. diff vaccine formulation(s) chosen in Phase 1. The Phase 2 portion of the study is seeking participants: * who are healthy adults ≥65 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. Phase 2 participants will receive active C. diff vaccine or placebo at each vaccination visit. Participants in Phase 2 will attend at least 6 and up to 12 study visits and will take part in the study for up to 4 years.
This is a prospective, multicenter, open-label Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence of CDI after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Subjects may receive a second RBX2660 enema if they are deemed treatment failures following the initial enema per the protocol-specified treatment failure definition.
To determine whether symptomatic treatment of the diarrhea in CDAD reduces morbidity and mortality of this serious nosocomial infection in patients who have antibiotic-associated diarrhea. Both C. diff positive and negative patients will be included.
