Trial summary

Patients with hip, knee and shoulder PJI, will be treated with a two-stage exchange Revision. Patients will be randomized into 2 groups: the experimental Group will get a reimplantation after a short interval (2-3 weeks) while the control Group after a long standard interval.

About this study

Official title: Efficacy and Safety of Fast-track Treatment for Prosthetic Joint Infection (PJI)

Patients with hip, knee and shoulder PJI, will be treated with a two-stage exchange Revision.

Patients will be randomized into 2 groups: the experimental Group will get a reimplantation after a short interval (2-3 weeks) while the control Group after a long standard interval.

Primary objective of the study is "Infection outcome". The infection-free status is defined as absence of clinical (e.g. no fistula), laboratory (e.g. normal C-reactive protein) and radiological signs of infection (e.g. no septic loosening).

Secondary objective is "Functional outcome".The functional assessment will be performed using joint-specific scores (HARRIS HIP SCORE, CONSTANT SHOULDER SCORE, KNEE SOCIETY SCORE, OXFORD HIP SCORE, OXFORD KNEE SCORE, QUICK DASH SCORE) involving the range of motion (ROM), patient mobility / independency in daily life, subjective evaluation of pain using a visual analog pain scale (1-10 points) and life-quality evaluation (EQ5D5L score).

Read the detailed description

A two-stage prosthesis exchange after a long interval of ≥6 weeks is considered the "gold standard" for management of prosthetic joint infection (PJI). We will compare the efficacy and safety of a novel surgical approach with short interval of 2-3 weeks ("fast-track") compared to the standard long interval of 6-10 weeks. Included will be patients with hip, knee or shoulder PJI, in whom all prosthetic components are removed; excluded will be patients treated with prosthesis retention or one-stage exchange and PJI caused by difficult-to-treat organisms. Patients will be randomized into short versus long interval surgical procedure, using a standard antibiotic regimen of 12 weeks in both study arms. The recruitment period of this multicenter treatment/outcome trial is 24 months, follow-up period 12 months and the calculated sample size 418 patients (i.e. 209 patient for each study arm). Primary endpoint is the infection outcome, secondary endpoint is the functional outcome, defined by established scores for joint-specific scores, pain and quality of life scores. The expected outcomes in the short interval ("fast-track") arm are (i) improved infection outcome (i.e. longer infection-free period and less treatment-related adverse events); (ii) improved functional outcome, and (iii) reduced healthcare expenses. In addition, pharmacokinetic studies will be performed and a biobank of microbes and biological samples will be established. This study has high clinical relevance for an increasing public health challenge related to device-associated infections.

What participants receive

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

  • Shortening of the interval of two-stage prosthesis exchangeProcedure or surgery

    The Intervention consist in shortening of the interval between Explantation and re-implantation in patients undergoing a two-stage prosthesis Exchange. Comparison between arms is performed between short and long interval before re-implantation.

What is being measured

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

  1. Infection outcome

    Duration of infection-free interval and frequency of adverse events related to surgical treatment. The infection-free status is defined as absence of clinical (e.g. no fistula), laboratory (e.g. normal C-reactive protein) and radiological signs of infection (e.g. no septic loosening).

    Measured: 12 months after surgery

Secondary outcomes (1)
  1. Functional outcome

    The functional assessment will be performed using joint-specific scores (HARRIS HIP SCORE, CONSTANT SHOULDER SCORE, KNEE SOCIETY SCORE, OXFORD HIP SCORE, OXFORD KNEE SCORE, QUICK DASH SCORE) involving the range of motion (ROM), patient mobility / independency in daily life, subjective evaluation of pain using a visual analog pain scale (1-10 points) and life-quality evaluation (EQ5D5L score).

    Measured: 12 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Shortening of the interval of two-stage prosthesis exchange in people with Hip Prosthetic Joint Infection and Knee Prosthetic Joint Infection, run by Charite University, Berlin, Germany.

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 3 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 26 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Results are not available in the source record.

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

Contact Antje Spranger (+4930450652416, antje.spranger@charite.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Infection outcome (time frame: 12 months after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 26 Feb 2015.
