简要总结
The purpose of this study is to evaluate the effects of Delafloxacin versus Vancomycin plus Aztreonam in the treatment of patients with acute bacterial skin and soft tissue infections.
详细描述
The purpose of this study is to determine if delafloxacin, an investigational drug, is safe and effective in the treatment of skin and nearby tissue infections compared with a combination of other antibiotics, vancomycin and aztreonam.

入选标准
- •Adult (≥ 18 years of age) men or women with a diagnosis of ABSSSI (cellulitis/erysipelas, wound infection, major cutaneous abscess, or burn infection) with surrounding redness of a minimum surface area of 75 cm^2 and at least two signs of systemic infection
- •In the opinion of the investigator, the subject must require and be a suitable candidate for IV antibiotic therapy, and the subject must be able and willing to comply with protocol requirements
排除标准
- •A medical history of significant hypersensitivity or allergic reaction to quinolones, beta-lactams, vancomycin, or vancomycin derivatives according to the judgment of the investigator.
- •Women who are pregnant or lactating.
- •Any chronic or underlying skin condition at the site of infection that may complicate the assessment of response, including infection involving a prosthetic joint, human or animal bite, osteomyelitis, decubitus ulcer, diabetic foot ulcer, septic arthritis, mediastinitis, necrotizing fasciitis, anaerobic cellulitis, or synergistic necrotizing cellulitis, myositis, tendinitis, endocarditis, sustained shock, gangrene or gas gangrene; burns covering ≥10% of body surface area; severely compromised immune system, severely impaired arterial blood supply to an extremity with an ABSSSI, deep vein thrombosis or superficial thrombophlebitis, and requiring either an amputation or multiple debridement procedures.
- •Receipt of systemic antibiotic therapy in the 14 days before enrollment unless 1 of the following was documented:
- •Received ≥ 48 hours of antibiotic therapy for ABSSSI AND clinical progression is documented (i.e., not by patient history alone).
- •Recently (within 14 days) completed a treatment course with an antibacterial drug for an infection other than ABSSSI and the drug does not have activity against bacterial pathogens that cause ABSSSI.
- •Received only 1 dose of either a single, potentially effective, short-acting antimicrobial drug or drug regimen for ABSSSI.
- •Any underlying disease that, in the opinion of the investigator, could interfere with the subject's ability to participate in the study including severe cardiac disease, known history of liver disease, end-stage renal disease, malignancy, psychiatric disorder, ongoing treatment for seizures or untreated history of seizures, or life expectancy of < 3 months.
研究组 & 干预措施

结局指标
主要结局
Objective Response of ≥20% Reduction in Lesion Erythema Area Compared to Baseline at 48 to 72 Hours After Initiation of Treatment as Determined by Digital Measurements of the Leading Edge.
时间窗: 48 to 72 hrs after starting treatment
A patient was considered a responder if s/he had a ≥20% reduction in size of the area of erythema associated with the baseline ABSSSI, as determined by digital planimetry of the leading edge and had none of the reasons for clinical failure; a patient was considered a non-responder (failure) if s/he had \<20% reduction in size of the area of erythema associated with the baseline ABSSSI as determined by digital planimetry of the leading edge, or had major intervention such as another antibiotic or surgical intervention or died within 74 hours after initiation of study drug.
次要结局
- Investigator-assessed Response of Signs and Symptoms of Infection at the Late Follow-up Visit(Study Day 21 to 28)
- Investigator-assessed Response of Signs and Symptoms of Infection at the Follow up Visit (European Medicines Agency [EMA] Primary Endpoint)(Study Day 14 ± 1)
