The purpose of this study is to learn if an experimental antibiotic calledTR-701 FA can safely and effectively treat a acute bacterial skin or skinstructure infection. The experimental antibiotic will be tested against thealready approved antibiotic Linezolid. The sponsor of the study wants toprove, that the new medication isn't inferior regarding efficacy andsafety as compared to the already approved medication Linezolid.

Inclusion Criteria

1. Males or females = 18 years old
2. ABSSSI meeting at least 1 of the clinical syndrome definitions listed below and requiring systemic oral antibiotic therapy. Local symptoms must have started within 7 days before the Screening Visit.
A. Cellulitis/erysipelas defined as a diffuse skin infection, characterized by all of the
following within 24 hours:
? Rapidly spreading areas of erythema of a minimum total lesion surface area of 75 cm2
? No collection of pus apparent upon visual examination (diagnosis still consistent with cellulitis/erysipelas if pus is collected from the lesion)
? At least 1 of the following signs of infection:
? Induration
? Localized warmth
? Pain or tenderness on palpation
? Swelling
? At least 1 of the following regional or systemic signs of infection:
? Lymph node tenderness and increase in volume or palpable proximal to the
primary ABSSSI
? Fever, defined as body temperature = 38°C (100.4°F) oral, = 38.5°C (101.3°F)
tympanic, or = 39°C (102.2°F) rectal (observed by a health care provider)
? White blood cell (WBC) count = 10,000 cells/mm3 or < 4000 cells/mm3
? > 10% immature neutrophils
B. Major cutaneous abscess defined as an infection characterized by a collection of pus apparent upon visual examination spreading within the dermis or deeper that is accompanied by all of the following within 24 hours:
? Erythema extending at least 5 cm in the shortest distance from the peripheral margin of the abscess and with a minimum total lesion surface area of 75 cm2
? At least 1 of the following signs of infection:
? Fluctuance
? Incision and drainage required
? Purulent or seropurulent drainage
? Localized warmth
? Pain or tenderness on palpation
? At least 1 of the following regional or systemic signs of infection:
? Lymph node tenderness and increase in volume or palpable proximal to the
primary ABSSSI
? Fever, defined as body temperature = 38°C (100.4°F) oral, = 38.5°C (101.3°F)
tympanic, or = 39°C (102.2°F) rectal (observed by a health care provider)
? WBC count = 10,000 cells/mm3 or < 4000 cells/mm3
? > 10% immature neutrophils
C. Wound Infection defined as an infection of any apparent break in the skin characterized by the following:
? Superficial incision surgical site infection (SSI) meeting all of the following criteria:
? Follows clean surgery (elective, not emergency, nontraumatic, primarily closed,
no acute inflammation; no break in technique; respiratory, gastrointestinal,
biliary, and genitourinary tracts not entered)
? Involves only the skin or subcutaneous tissue around the incision, does not
involve fascia
? Occurs within 30 days after procedure
? Original surgical incision = 3 cm
? Purulent drainage (spontaneous or therapeutic) with surrounding erythema extending at least 5 cm in the shortest distance from the peripheral margin of the wound and with a minimum total lesion surface area of 75 cm2
? At least 1 of the following regional or systemic signs of infection:
- Lymph node tenderness and increase in volume or palpable proximal to the
primary ABSSSI
- Fever, defined as body temperature = 38°C (100.4°F) oral, = 38.5°C
(101.3°F) tympanic, or = 39°C (102.2°F) rectal (observed by a health care
provider)
- WBC count = 10,000 cells/mm3 or < 4000 cells/mm3
- > 10% immature neutrophils
? Post-traumatic wound (including penetrating trauma [needle, nail, kn

Exclusion Criteria

1.Uncomplicated skin and skin structure infections such as furuncles, minor abscesses (area of suppuration not surrounded by cellulitis/erysipelas), impetiginous lesions, superficial or limited cellulitis/erysipelas, and minor wound infections (eg, stitch abscesses)
2. Infections associated with, or in close proximity to, a prosthetic device
3. Severe sepsis or septic shock
4. Known bacteremia at time of screening
5. ABSSSI due to or associated with any of the following:
? Suspected or documented gram-negative pathogens in patients with
cellulitis/erysipelas or major cutaneous abscess that require an antibiotic with specific
gram-negative coverage. Patients with wound infections where gram-negative
adjunctive therapy is warranted may be enrolled if they meet the other eligibility
criteria
? Diabetic foot infection, gangrene, or perianal abscess
? Concomitant infection at another site not including a secondary ABSSSI lesion (eg,
septic arthritis, endocarditis, osteomyelitis)
? Infected burns
? Decubitus or chronic skin ulcer, or ischemic ulcer due to peripheral vascular disease
(arterial or venous)
? Any evolving necrotizing process (ie, necrotizing fasciitis)
? Infected human or animal bites. However, arthropod (eg, insects, spiders, ‘bugs’) bites are allowed; these are not considered animal bites in this study
? Infections at vascular catheter sites or involving thrombophlebitis
? Incision SSI with any of the following characteristics:
? Follows clean-contaminated surgery (urgent or emergency case that is otherwise clean, elective opening of respiratory, gastrointestinal, biliary, or genitourinary tract with minimal spillage [eg, appendectomy] not encountering infected urine or bile; minor technique break)
