简要总结
This will be a prospective, open-label, two-center study to assess the safety of omadacycline use in the treatment of hospitalized subjects with moderate to severe DFI with or without Acute osteomyelitis (AOM) who are at a high risk for development of CDI, AKI, and/or resistant pathogens compared to retrospective controls. Prospective enrollment will be continued until the sample size is achieved up to one year from start date (October 2020).
Secondary to slower than anticipated enrollment due to the COVID-19 pandemic and initial exclusion of AOM, following protocol amendment, patient enrollment will be continued until the sample size is achieved up to 18 months from amendment approval (anticipate April 2022 - October 2023). A historical matched case cohort (standard of care) at the two hospitals based on ICD10 codes associated with DFI [E11.(621, 622), E10.(621, 622); L97.(509, 521, 522, 523, 524, 529)], including subjects with AOM [M86.(08-09, 10, 16-19, 8X0, 8X7-8X9, 9) will be utilized for comparison.
详细描述
This is a year-long study with planned enrollment of 57 patients (in addition to 114 historical control patients) evaluating the use of omadacycline for treatment of diabetic foot infections (DFI). Omadacycline (Nuzyra®) is a FDA approved antibiotic for skin and skin structure infection and community-acquired pneumonia. This study is considered to be investigational because data is being collected on the use of Omadacycline for the treatment of DFI with or without AOM.

入选标准
- •Female and male subjects will be eligible for inclusion if hospitalized, 18 years or older, diagnosed with type 1 or 2 diabetes, and have DFI with the additional clinical criteria as specified below:
- •Acute infection or worsening without systemic antimicrobials within the previous 14 days
- •At least one full or partial thickness-infected ulcer at or below the ankle AND
- •Purulent drainage OR
- •Two of the following:
- •Local edema
- •Fluctuance
- •Induration
- •Increased local warmth
- •No systemic antimicrobials with current hospital admission for more than 48 hours prior to enrollment
- •Inclusion will be based on
- •Empiric coverage based on organisms suspected to be caused by susceptible bacteria, if no culture identifies a specific organism; or
- •Confirmed susceptibility to omadacycline against any organism identified. Any subject in which a pathogen resistant to omadacycline is identified will be excluded from the study and antibiotics will be changed based on physician discretion.
- •First episodes of AOM at qualifying site of infection will be eligible for inclusion with any of the following criteria confirming the diagnosis:
- •Imaging (X-ray or MRI) confirmation of acute osteomyelitis
- •Pathology (bone biopsy/culture)
- •Not currently enrolled in any other clinical trial
- •Provides informed consent
- •Likely to be compliant with all study-related procedures and visits
排除标准
- •Age less than 18 years
- •Pregnant women
- •Chronic osteomyelitis
- •Osteomyelitis of the same site previously treated with antibiotics
- •Documented presence of osteomyelitis more than 2 weeks prior to index admission
- •Necrotic or dead bone identified by pathology
- •Unclear chronicity of infection (if unable to determine acute osteomyelitis)
- •Has any gangrenous ulcers or necrotizing fasciitis
- •Has a pathogen known to be resistant to omadacycline
- •Administration of additional systemic antibiotics in combination with omadacycline, not including topical routes or oral vancomycin/fidaxomicin given their local activity within the GI tract
- •Contraindication or hypersensitivity to omadacycline/tetracyclines
- •Unwilling or unable to participate in study-related procedures or visits
研究组 & 干预措施
Prospective Cohort
Subjects will be screened daily via review of the EMR reports of inpatient admissions. Those receiving antibiotics with a notated source of skin/soft tissue infection or OM will be further reviewed to determine if the source of infection is a DFI with or without suspected or confirmed Acute osteomyelitis.
干预措施: Omadacycline (Drug)
