Omadacycline Tissue Penetration in Diabetic Patients With Wound Infections and Healthy Volunteers Via In Vivo Microdialysis

Completed · Phase 1

Conditions studied: Diabetes, Wound Infection, Healthy Volunteers

In brief

This study will determine the tissue penetration of the novel tetracycline antibiotic, omadacycline (Nuzyra, Paratek Pharmaceuticals, Inc.), into the extracellular, interstitial fluid of soft tissue in diabetic patients with lower limb wound infections. Penetration will be compared with a group of healthy volunteer control participants.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Experimental: Type 1 or Type 2 diabetes and a mild to moderate (Grade 2 or 3) wound infection of the lower limb
• Active Comparator: Healthy Adult Volunteer

You may not qualify if…

• Participants in the study or control group will be excluded if any of the following criteria are met:
• Less than 18 years of age
• History of hypersensitivity to omadacycline or any tetracycline based molecule
• History of hypersensitivity to lidocaine or lidocaine derivatives
• Pregnant or breastfeeding
• Concomitant receipt of any tetracycline based antibiotic therapy
• Any other documented reason felt by the investigator to potentially affect the outcomes of the study
• Additional Exclusion Criteria for Diabetic Patient Study Group:
• Participants likely to require multiple surgical interventions during the study period, which therefore could affect placement of the microdialysis catheter
• Additional Criteria for Healthy Volunteer Control Group:
• Body Mass Index (BMI) ≥ 35 kg/m2
• Serum creatinine greater than 1.5 mg/dl or creatinine clearance (CrCl) < 50ml/min, as calculated by Cockroft-Gault using ideal body weight for all participants
• Presence of anemia, thrombocytopenia, or leukopenia as defined by hematocrit, platelet, or white blood cell count < 75% of the lower limit of normal
• Aspartate transaminase, alanine aminotransferase, or alkaline phosphatase greater than five times upper limit of normal
• Total bilirubin greater than three times the upper limit of normal
• Any known active co-morbidity listed on medical history or that becomes apparent during physical examination
• Positive urine drug screen (cocaine, THC, opiates, benzodiazepines, and amphetamines)
• History of regular alcohol consumption exceeding 7 drinks/week for females or 14 drinks/week for men (1 drink = 5 ounces of wine or 12 ounces of beer or 1.5 ounces of hard liquor) within 6 months of screening.
• Use of tobacco- or nicotine-containing products in excess of the equivalence of 5 cigarettes per day.
• Consumption of caffeine between Study Days 1 and 4
• Use of prescription or nonprescription drugs, vitamins, or dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication, with the exception of acetaminophen at doses of ≤ 1 g/day. The use of hormonal methods of contraception (including oral and transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone-releasing IUDs, postcoital contraceptive methods) are permitted.
