E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether ceftaroline fosamil is noninferior to vancomycin plus aztreonam in the clinical cure rate at the test of cure visit in both the modified intent-to-treat and clinically evaluable anlaysis sets of adult patients with complicated skin and soft tissue infections (cSSTI) |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the clinical response at the End of Therapy Visit.
To evaluate the microbiological response at the End of Therapy and Test of Cure Visits
To evaluate the clinical and microbiological response by baseline pathogen at the Test of Cure Visit
To evaluate clinical relapse and re-infection or recurrence at the Late Follow-Up
(LFU) visit
To evaluate superinfection, colonisation and new infection up to TOC and microbiological recurrence and re-infection at LFU
To evaluate early response to treatment as defined by cessation of lesion spread at 48 to 72 hours of treatment
To compare the safety and tolerability of ceftaroline fosamil and vancomycin plus aztreonam in patients with cSSTI
To characterize the pharmacokinetics (PK) and exposure-response relationship of 600 mg of ceftaroline fosamil administered as a 120-minute intravenous (IV) infusion every 8 hours in patients with cSSTI

E.3 | Principal inclusion criteria |
1. Patient must provide a signed written informed consent prior to any study-specific procedures
2. Patient must be a male or female, aged 18 years and older
3. Patient must have one of the following cSSTIs:
- Cellulitis: a diffuse skin infection characterised by spreading areas of erythema, oedema, and/or induration of a minimum surface area of 75 cm2 (eg, minimum length of 10 cm and width of 7.5 cm)
- Traumatic or surgical wound infection: an infection characterised by purulent drainage/or collection from an injury-related wound or a surgical wound with surrounding erythema, oedema, and/or induration of a minimum surface area of 75 cm2 (eg, the shortest distance of redness, oedema, and/or induration extending at least 5 cm from the peripheral margin of the wound). Appropriate surgical intervention must be completed prior to the first dose of study drug or up to, at most, 48 hours after the first dose of study drug.
- Major cutaneous abscess: an infection characterised by a collection of pus within the dermis or deeper that is accompanied by erythema, oedema, and/or induration of a minimum surface area of 75 cm2 (eg, the shortest distance of redness, oedema, and/or induration extending at least 5 cm from the peripheral margin of the abscess).

Burns must involve less than 15% of the body surface area and acquired within 7 days of hospitalisation. Appropriate surgical intervention must be completed prior to the first dose of study drug or up to, at most, 48 hours after the first dose of study drug.

− Cirrhosis with Child-Pugh Stage A or B (note: patients with Child-Pugh
Stage C are excluded)
− cSSTI below the knee associated with peripheral vascular disease diagnosed on the basis of any of the following: claudication at a distance of at least 20 meters; resting ankle-brachial index 0.3 to 0.8; prior femoral artery bypass grafting; or prior aortic aneurysm repair (note: patients with ulcers due to peripheral vascular disease are also excluded)
− Albumin <2.5 mg/dL or prealbumin <11 mg/dL in the absence of liver disease
− Use of immunosuppressive agents, including a glucocorticoid (Note: patient who is receiving or has received >40 mg per day of prednisone or equivalent for more than 1 week within the 2 weeks prior to study enrolment is excluded)
− Malignancy, other than nonmelanoma skin cancers, with a life expectancy of >3 months
5. Patient must have an infection of sufficient severity to warrant hospitalisation
6. Patient must have an infection of sufficient severity such that it is expected to require at least 5 days of IV antibiotic therapy
7. Female patients of childbearing potential may be entered if pregnancy testing is negative and the patient agrees to abstain from procreational sexual intercourse or must use double-barrier contraceptive measures for the duration of the study |
