Safety and Efficacy of an Antibiotic Sponge in Diabetic Patients With a Mild Infection of a Foot Ulcer

Completed · Phase 2

Conditions studied: Diabetic Foot Ulcer

In brief

The purpose of this study is to determine whether the gentamicin-collagen sponge when combined with standard of daily wound care is safe and effective in treating mildly infected skin ulcers compared to treatment with an oral antibiotic (levofloxacin) and standard daily wound care.

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Is a man or woman aged 18 to 80 years.
• Has diabetes mellitus, according to the American Diabetes Association criteria.
• Has a single infected skin ulcer below the knee, defined as "mild" by the Infectious Disease Society of America (IDSA) Guidelines, for whom, in the Investigator's judgment, topical or oral antimicrobial therapy is appropriate (Mild infection severity: The presence of ≥ 2 manifestations of inflammation (purulence or erythema, pain, tenderness, warmth or induration) but any cellulitis/erythema extends ≤ 2 cm around the ulcer, and the infection is limited to the skin or superficial subcutaneous tissue, with no other local complications or acute, systemic illness).
• Has had an x-ray of the infected area within the 2 days immediately preceding or at Visit 1 (Baseline/Randomization) that is negative for osteomyelitis.
• Meets the certain minimal laboratory criteria
• Has an ankle-brachial index (ABI) ≥ 0.7 and ≤ 1.3. (Note: Patients with ABI < 0.7 or > 1.3 may be included if they have either a transcutaneous oxygen pressure or a toe pressure ≥ 40 mm Hg on the limb with the target ulcer.)
• If female, is nonpregnant (negative pregnancy tests at the Baseline/Randomization Visit) and nonlactating.
• If female, is either not of childbearing potential (defined as postmenopausal for ≥ 1 year or surgically sterile [bilateral tubal ligation, bilateral oophorectomy or hysterectomy]) or practicing 1 of the following medically-acceptable methods of birth control and agrees to continue with the regimen throughout the duration of the study:
• Oral, implantable or injectable contraceptives for 3 consecutive months before the Baseline/Randomization Visit
• Total abstinence from sexual intercourse (≥ 1 complete menstrual cycle before the Baseline/Randomization Visit)
• Intrauterine device (IUD)
• Double barrier method (condoms, sponge, diaphragm or vaginal ring with spermicidal jellies or cream)
• Willing to return to the study facility for the Final Study Visit.
• Must be able to fluently speak and understand English and be able to provide meaningful written informed consent for the study

You may not qualify if…

• Has a known history of hypersensitivity to gentamicin (or other systemic aminoglycosides) or levofloxacin or drugs in the same class, or any of the test article or reference product components.
• Has a known hypersensitivity to bovine collagen.
• Has any uncontrolled illnesses that, in the opinion of the Investigator, would interfere with interpreting the results of the study.
• Has an infecting pathogen known to be intermediate or resistant in vitro to levofloxacin. Patients enrolled into the study presumptively will be discontinued if their cultured organism is intermediate or resistant to levofloxacin.
• Has a target ulcer with a wound size > 5 × 5 cm.
• Has gangrenous tissue of the affected limb that cannot be removed with a single debridement.
• Has a wound associated with prosthetic material or device.
• Received any topical or systemic antimicrobial therapy within the 2 weeks prior to study entry (Visit 1 [Day 1]).
• Has documented osteomyelitis.
• If severely immunocompromised, may be excluded at the discretion of the Investigator.
• Has a history of alcohol or substance abuse in the past 12 months.
• Is undergoing dialysis (renal or peritoneal) or has history of kidney transplant.
• Has a history of myasthenia gravis or other neurological condition where gentamicin use is contraindicated as determined by the Investigator.
• Has a history of epilepsy
• Has a history of tendon disorders related to fluoroquinolone administration
