Ceftobiprole in the Treatment of Patients With Acute Bacterial Skin and Skin Structure Infections
A Randomized, Double-blind, Multicenter Study to Establish the Safety and Efficacy of Ceftobiprole Medocaril Compared With Vancomycin Plus Aztreonam in the Treatment of Acute Bacterial Skin and Skin Structure Infections

Intervention / Treatment
Detailed Description
This was a randomized, double-blind, active-controlled, parallel-group, multicenter study in adult hospitalized patients with ABSSSIs. Randomization was stratified by study site and type of ABSSSI (with major cutaneous abscess comprising ≤ 30% of the Intent-to-Treat [ITT] population).
Primary endpoint for FDA: Early clinical response based on the percent reduction in lesion size at 48-72 hours compared to baseline in patients who did not receive rescue therapy and were alive, in the ITT population.
Primary endpoint for EMA: Investigator-assessed clinical success at the test-of-cure (TOC) visit 15-22 days after randomization, in the co-primary ITT and Clinically Evaluable (CE) populations.

The primary ABSSSI is due to, or associated with, any of the following:
- Diabetic foot infection, gangrene, or perianal abscess.
- Concomitant infection at another site (e.g., septic arthritis, endocarditis, osteomyelitis), not including a secondary ABSSSI lesion.
- Infected burns.
- Decubitus or chronic skin ulcer, or ischemic ulcer due to peripheral vascular disease (arterial or venous).
- Any evolving necrotizing process (e.g., necrotizing fasciitis).

- Patients expected to require more than two surgical interventions in the operating room for the ABSSSI.
- Severe sepsis or septic shock.
- Significant or life-threatening condition (e.g., endocarditis, meningitis) that would confound, or interfere with, the assessment of the ABSSSI.
- Another severe, acute or chronic medical condition, psychiatric condition, or laboratory abnormality that may increase the risks associated with study participation or administration of the investigational product, or may interfere with the interpretation of study results, and which, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
- Receiving treatment for active tuberculosis.
- Absolute neutrophil count < 0.5 × 10^9/L.
- Recent history of opportunistic infections (i.e., within 30 days) if the underlying cause of these infections is still active (e.g., leukemia, transplant, acquired immunodeficiency syndrome [AIDS]).
- Patients receiving systemic steroids (> 40 mg per day prednisolone, or equivalent), or receiving immunosuppressant drugs.
- Requirement for peritoneal dialysis, plasmapheresis, hemodialysis, venovenous dialysis, or other forms of renal filtration, or expected to require such treatment before the TOC visit.

Intervention / Treatment |
---|---|
Experimental: ceftobiprole medocaril
Patients treated with ceftobiprole medocaril 500 mg q8h (with dose adjustment for renal impairment).
|
ceftobiprole 500 mg was to be administered every 8 hours as a 2-hour IV infusion (with dose adjustment for renal impairment).
The treatment duration was for a minimum of 5 days and a maximum of 10 days.
Treatment could be extended up to 14 days if in the investigator's opinion this was required, and the extension was approved by the sponsor's medical monitor.
Other Names:
|
Active Comparator: vancomycin+aztreonam
Patients treated with vancomycin 1000 mg (or 15 mg/kg) q12h plus aztreonam 1000 mg q12h (both with dose adjustment for renal impairment).
|
Vancomycin 1000 mg (or 15 mg/kg) was to be administered every 12 hours (with dose adjustment for renal impairment) as 2-hour IV infusion. Vancomycin dose adjustment for morbidly obese and hypermetabolic patients was to be done according to local standard of care. When locally available, vancomycin trough testing (VTT) might have been used by the unblinded pharmacist or delegate to adjust the vancomycin dose. The treatment duration was for a minimum of 5 days and a maximum of 10 days. Treatment could be extended up to 14 days if in the investigator's opinion this was required, and the extension was approved by the sponsor's medical monitor. Aztreonam 1000 mg was to be administered as a 0.5-hour IV infusion every 12 hours. If CLCR was < 30 mL/min (i.e., severe renal impairment), the aztreonam dosage regimen was to be adjusted. The requirement to continue aztreonam therapy beyond Day 3 was to be reassessed at the 72-hour study visit. |
