What researchers measure

Primary outcomes

  1. Clinical Response Rate at Test of Cure in the Clinically Evaluable Analysis Set

    Clinical response was defined as resolution or improvement of signs and symptoms of the complicated skin and skin structure infection so that no further antibiotic therapy was required.

    Time frame: 7 to 14 days after the last dose of study drug

  2. Clinical Response Rate at Test of Cure in the Clinical Modified Intent to Treat Analysis Set

    Clinical response was defined as resolution or improvement of signs and symptoms of the complicated skin and skin structure infection so that no further antibiotic therapy was required.

    Time frame: 7-14 days after last dose of study drug

Secondary outcomes

  1. Response Rate at End of Therapy

    Clinical response was defined as resolution or improvement of signs and symptoms of the complicated skin and skin structure infection so that no further antibiotic therapy was required.

    Time frame: last day of study treatment

  2. Microbiological Response Rate at Test of Cure in the Microbiologically Evaluable Analysis Set

    Satisfactory microbiological outcomes are eradication and presumed eradication

    Time frame: 7-14 days after last dose of study drug

  3. Clinical Outcome at the Late Follow-up Visit in the Clinical Modified Intent to Treat Analysis Set

    Persistent clinical cure was defined as continuing favorable response.

    Time frame: 21 to 28 days after the last study drug

  4. To Evaluate the Safety Profile of Tedizolid Phosphate

    Time frame: Multiple

  5. Population PK

    Time frame: Multiple

  6. Microbiological Recurrence at Late Follow-up in Clinical Modified Intent to Treat Analysis Set

    Time frame: 21-28 days after last study drug
