Use Of Oral Fidaxomicin Vs. Oral Vancomycin For Clostridium Difficile Infection In Patients With Spinal Cord Injury

October 12, 2016 updated by: Rabih Darouiche, Baylor College of Medicine

Role of Fidaxomicin in a Patient Population With Problematic Clostridium Difficile Infection

The primary purpose of this study is to compare the clinical outcomes of cure and recurrence of Clostridium difficile infection in spinal cord injured patients who are treated with oral Fidaxomicin vs. oral Vancomycin. The secondary aim of this study is to compare the overall costs of treatment of Clostridium difficile infection in the two study groups.

Detailed Description

In recent clinical trials, comparing oral Vancomycin versus oral Fidaxomicin to treat Clostridium difficile, oral Fidaxomicin was shown to be the same in effectiveness as oral Vancomycin, but showed a decrease in recurrence of Clostridium difficile by ten percentage points. Based on experience with patients in our 40-bed spinal cord injury unit at the Michael E. DeBakey VA Medical Center (MEDVAMC), Clostridium difficile infection is more problematic in patients with spinal cord injury than in the general hospitalized patient population. Compared to the general population of hospitalized patients, patients with spinal cord injury are more likely to have: (1) a higher transmission of Clostridium difficile from one patient to another often via the health care worker due to their having a neurogenic bowel (2) a longer and more complicated course of Clostridium difficile infection-associated diarrhea since neurogenic bladder may delay excretion of toxins and predispose to bowel accidents; and (3) a higher overall cost of treatment in terms of extended hospitalization (most patients with spinal cord injury who suffer from Clostridium difficile infection do not get discharged from the hospital until the symptoms of course of Clostridium difficile infection are resolved. Fidaxomicin is the first in a new class of narrow spectrum macrocyclic antibiotic drugs. It is a non-systemic, meaning it is minimally absorbed into the bloodstream, and it is bactericidal, meaning it attacks and kills the bacteria it comes in contact with. It has demonstrated selective eradication of pathogenic Clostridium difficile with minimal disruption to the numerous species of bacteria that make up the normal, healthy intestinal flora. The maintenance of normal physiological conditions in the colon can reduce the probability of recurrence of a Clostridium difficile infection. Since clearance of Clostridium difficile infections is problematic in the spinal cord injured patients, this antimicrobial agent may show a trend for clinical superiority and a reduction in recurrence of infection within the spinal cord injury population resulting in a shorter hospital stays and reduced costs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
