Trial Outcomes & Findings for Study to Compare Efficacy and Safety of Daptomycin in Elderly Patients With Complicated Skin and Soft Tissue Infections (NCT NCT01184872)

NCT ID: NCT01184872

Last Updated: 2012-07-13

Results Overview

Success: Clinically significant signs and symptoms associated with the skin infection present at the pre-treatment infection site resolved (cure), or improved without need of further antibacterial therapy. Failure: Persistence or progression of signs and symptoms or development of new clinical signs and symptoms at the infection site, or concomitant antibacterial therapy with activity against isolated organisms, or treatment duration longer than pre-specified, or switch back to intravenous therapy due to relapse, or requirement of a major surgical procedure as adjunct or follow-up therapy.

PRIMARY outcome

Timeframe: Baseline and 7 to 14 days after end of therapy

Population: The clinically evaluable population was used for the efficacy analysis. It included all patients who met the criteria for complicated skin and soft tissue, had no substantive protocol deviation, had a sponsor clinical response assessment of "success" or "failure" at the assessment visit, and had a specified baseline primary site of infection.

Success: Clinically significant signs and symptoms associated with the skin infection present at the pre-treatment infection site resolved (cure), or improved without need of further antibacterial therapy. Failure: Persistence or progression of signs and symptoms or development of new clinical signs and symptoms at the infection site, or concomitant antibacterial therapy with activity against isolated organisms, or treatment duration longer than pre-specified, or switch back to intravenous therapy due to relapse, or requirement of a major surgical procedure as adjunct or follow-up therapy.

SECONDARY outcome

Timeframe: Baseline and 7 to 14 days after end of therapy

Population: Population analyzed consisted of patients from the clinically evaluable population who had independent microbiological assessments.

Microbiological Success: All infecting Gram-positive pathogens isolated at baseline were eradicated or presumed to be eradicated at the Test-of-Cure (TOC) evaluation and a super infecting pathogen was not isolated either prior to or at the TOC evaluation. Microbiological Failure: Persistence or relapse / re-infection of one or more infecting Gram-positive pathogens or isolation of a super infecting pathogen prior to or at the TOC evaluation.

SECONDARY outcome

Timeframe: Up to 28 days

Population: The Full Analysis Set (FAS) comprised all patients to whom study treatment had been assigned at randomization.

Duration of treatment is the interval from first to last intravenous (i.v.) administration. It was preferable that a patient complete the whole antibiotic treatment with the randomized i.v. study drug only. Duration of treatment in patients with bacteremia could be extended up to 28 days.

Duration of treatment is the interval from first to last intravenous (i.v.) or to last oral administration if patients switched to an oral antibiotic therapy.
