About this study

Official title: Daptomycin Use For Prophylaxis In Prosthetic Joint Surgery, A Randomized Prospective Study Comparing The Efficacy Of Daptomycin Versus Vancomycin For Peri-Operative Antibiotic Prophylaxis In MRSA Colonized Adult Patients Undergoing Primary Elective Hip, Knee or Shoulder Arthroplasty

This study will evaluate the safety and effectiveness of daptomycin, an antibiotic compared to another one which is vancomycin when given around the time of joint replacement surgery. Vancomycin is recommended for perioperative prophylaxis in methicillin resistant Staphylococcus aureus (MRSA) colonized patients undergoing primary total joint arthroplasty. Daptomycin has not been recommended for this indication but it is FDA approved for treatment of MRSA blood stream and skin and soft tissue infections. Data collected during this study may support the use of daptomycin for this indication and may also be used for other research purposes that have not yet been specified.

Read the detailed description

This is a phase 4 randomized open label prospective pilot study comparing the use of daptomycin versus vancomycin for peri-operative antibiotic prophylaxis in patients undergoing elective primary knee, hip or shoulder arthroplasty and are at risk for infection with methicillin resistant Staphylococcus aureus. The study population will include males and non-pregnant, non-lactating females 18 years of age or older, with history of methicillin-resistant Staphylococcus aureus infection or colonization, and undergoing primary elective hip, knee or shoulder arthroplasty. The target enrollment is 100 patients, who will be randomized to daptomycin or vancomycin in two 50 patient study groups. After signing the informed consent, patients will undergo pre-enrollment nasal screening for methicillin resistant Staphylococcus aureus to identify eligible patients. Patients with positive MRSA nasal screen will proceed with enrollment and get randomized into one of the two study groups. In one group, patients will receive one dose of daptomycin 6 mg/kg to be infused over 30 minutes. In this group, the infusion should be started and completed within 60 minutes of surgical incision. In the second group, patients will receive one dose of vancomycin 15 mg/kg to be infused over 1-2 hours of surgical incision according to the dose to avoid red man syndrome. In this group, the infusion should be started and completed within 120 minutes of surgical incision. After surgery, a second similar dose of vancomycin will be given 12 hours after the first dose to patients with creatinine clearance (CLcr.) of ≥50 ml/min. All patients in both groups will be asked to shower with chlorhexidine skin cleanser (HIBICLENS®) once daily from the neck down for 7days before surgery and apply Mupirocin ointment 2% to their nostrils twice daily for 5 days before surgery.

The patients will be evaluated on the day of surgery, at 2-3 days postoperatively, on discharge, at one month and three months follow up visits. During these study evaluations, patients will be assessed clinically for signs and symptoms of wound, and prosthetic joint infection (including pain, tenderness, swelling, erythema, poor wound healing and wound drainage) prior to hospital discharge, and at one, and three months follow up visits. Blood work including complete blood counts, erythrocytic sedimentation rate, c-reactive protein, and cultures will be ordered if clinical findings suggest infection. Bacterial isolates causing infections will be tested locally for antibiotic susceptibilities including daptomycin and vancomycin and saved for further testing if needed. Adverse effects and tolerability will be documented with the use of both drugs in the two patient groups. Data will be collected and analyzed with appropriate testing. The primary endpoint will be the success in prevention of postoperative SSI and prosthetic joint infection at one month postoperative follow up visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DaptomycinDrug

    Also called Cubicin

    One dose of Daptomycin 6 mg/Kg iv, will be infused over 30 minutes. The infusion will start no longer than one hour prior to surgical incision of primary knee or hip prosthetic joint arthroplasty.

  • VancomycinDrug

    Two doses of vancomycin 15 mg/Kg iv, with a maximum of 2 grams with each dose be infused over 60-120 minutes according to the dose. The first dose infusion will start no longer than one hour (if ≤ one gram), or no longer than two hours (if > one gram) prior to surgical incision of primary knee or hip prosthetic joint arthroplasty. A second similar dose will be given 12 hours after the first dose unless the patient has a creatinine clearance of < 50 ml/min. Patients with creatinine clearance of < 50 ml/min will only receive one dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Daptomycin efficacy in prevention of postoperative surgical site infection (SSI)

    Efficacy of daptomycin in preventing postoperative SSI will be determined for each enrolled subject on one month postoperative visit. Overall efficacy of daptomycin among the patient group who receive it will be compared to overall efficacy of vancomycin among the second patient group who receive vancomycin upon anticipated complete enrollment study at 24 months.

    Measured: 24 months

Secondary outcomes (1)
  1. Efficacy of daptomycin in preventing postoperative early prosthetic joint infection

    Efficacy of daptomycin in preventing postoperative early prosthetic joint infection will be determined for each enrolled subject on three months postoperative visit. Overall efficacy of daptomycin among the patient group who receive it will be compared to overall efficacy of vancomycin among the second patient group who receive vancomycin upon anticipated completion of the study at 30 months

    Measured: 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Daptomycin and Vancomycin in people with Staphylococcal Infections and Methicillin-resistant Staphylococcus Aureus, run by Mountain Home Research & Education Corporation at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 3 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: The study is closed to accrual. Enrollment of new patients stopped at the request of CUBIST Pharmaceuticals due to slow rate of enrollment.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Daptomycin efficacy in prevention of postoperative surgical site infection (SSI) (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01196169, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2014; AzTrials last refreshed its copy on 30 Oct 2026.
