Condition(s) targeted: Osteomyelitis

Phase: Phase 2

Status: Completed

This is a research study designed to look at the efficacy and safety of daptomycin given at a dose of 6 mg/kg or 8 mg/kg in subjects being treated for prosthetic hip or knee infections caused by Staphylococci. These types of bacteria are among the most common types of bacteria causing infections of prosthetic joints.

Clinical Details

Official title: A Phase 2 Randomized Study Investigating the Safety, Efficacy and Pharmacokinetics of Daptomycin 6 mg/kg and 8 mg/kg Versus Comparator in the Treatment of Subjects Undergoing Surgical Standard of Care for Osteomyelitis Associated With an Infected Prosthetic Hip or Knee Joint Caused by Staphylococci

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Any Creatine Phosphokinase (CPK) Elevation > 500 Units Per Liter (U/L)

Secondary outcome:

Safety - Notable Laboratory Abnormalities

Overall Clinical Outcome

Microbiological Response

Pharmacokinetic Parameter: Maximum Plasma Concentration (Cmax)

Pharmacokinetic Parameter: Area Under the Concentration-time Curve During a Dosing Interval at Steady State (AUCss)


Minimum age: 18 Years. Maximum age: 80 Years. Gender(s): Both.


Inclusion Criteria:

- Subject must be between the ages of 18 and 80, inclusive

joint which has never previously been totally revised because of an infection and for which they are anticipated to undergo a two-stage replacement surgery

- Subject must have a positive microbiological identifier of staphylococci.

- If Subject is female of childbearing potential, must be willing to practice reliable

- Subject has an abnormal creatine phosphokinase (CPK) (elevated CPK level ≥ 2x ULN) at

baseline as measured by central laboratory

- Subject is currently under treatment with chemotherapeutic agents excluding chronic

maintenance therapy (e. g. tamoxifen to prevent relapse of primary breast cancer)

- Subject is pregnant, nursing, or lactating.

- Subject is receiving or is expected to receive chronic immunosuppressive therapy

during the study.
