Trial Outcomes & Findings for Phase 4 Efficacy and Safety Study of Cubicin® With and Without Combination Therapy in S. Aureus Infective Endocarditis (SAIE) (NCT NCT00638157)

NCT ID: NCT00638157

Last Updated: 2021-02-02

Results Overview

The End of Treatment (EOT)/Early Termination (ET) visit occurred on the day that therapy was stopped or up to 2 days after the last dose of daptomycin. The Test of Cure (TOC)/Safety visit occurred 21 to 28 days after the last dose of daptomycin therapy. The overall median duration of treatment was 13.0 days in both the daptomycin group and the combination therapy group. The definition of elevated serum creatinine at baseline is \>3.0 mg/dL, and not elevated is ≤3.0 mg/dL. Clinically significant increases in serum creatinine is defined as an increase ≥0.5 mg/dL for patients with a baseline value ≤3.0 mg/dL or ≥1.0 mg/dL for patients with a baseline value \>3.0 mg/dL.

PRIMARY outcome

Timeframe: Baseline, EOT Visit, TOC

Population: Safety Population includes all patients who received any dose of study medication.

The End of Treatment (EOT)/Early Termination (ET) visit occurred on the day that therapy was stopped or up to 2 days after the last dose of daptomycin. The Test of Cure (TOC)/Safety visit occurred 21 to 28 days after the last dose of daptomycin therapy. The overall median duration of treatment was 13.0 days in both the daptomycin group and the combination therapy group. The definition of elevated serum creatinine at baseline is \>3.0 mg/dL, and not elevated is ≤3.0 mg/dL. Clinically significant increases in serum creatinine is defined as an increase ≥0.5 mg/dL for patients with a baseline value ≤3.0 mg/dL or ≥1.0 mg/dL for patients with a baseline value \>3.0 mg/dL.

SECONDARY outcome

Timeframe: TOC Visit

Population: Modified Intent-to-Treat (mITT) population includes all ITT patients who received at least one dose of study medication.

TOC/Safety visit occurred 21 to 28 days after the last dose of daptomycin therapy. Clinical response was assessed by the investigator as cure, improvement, failure, and unable to evaluate. Microbiological response, which was determined by the sponsor based on review of baseline and post-baseline culture results, included success, failure, and nonevaluable. TC=Treatment Cure; TF=Treatment Failure; TI=Treatment Improved.
