About this study

Official title: A Randomized, Controlled Clinical Study to Evaluate the Safety and Effectiveness of CORTOSS® Synthetic Cortical Bone Void Filler in Vertebral Augmentation

Doctors are studying an investigational treatment to be used during the vertebroplasty procedure when treating vertebral compression fractures (spine fractures) that may help to reduce pain and restore mobility. If one has experienced back pain for at least 4 weeks but not longer than 1 year, he/she may be eligible to participate.

The purpose of this protocol is to describe the methods for the clinical evaluation of Cortoss for vertebroplasty in patients with painful osteoporotic compression fractures.

Eligible patients with painful osteoporotic compression fractures of the spine are divided into two groups. Each enrolled patient will have the vertebroplasty procedure; however one group of patients will have the vertebroplasty procedure using polymethylmethacrylate [PMMA] (a Food and Drug Administration [FDA]-approved bone cement) and the other group of patients will have the vertebroplasty procedure using a relatively new (investigational) biomaterial called Cortoss.

Read the detailed description

This is a prospective, multi-center randomized, controlled study designed to evaluate the safety and effectiveness of Cortoss® Synthetic Cortical Bone Void Filler in vertebral augmentation using the percutaneous vertebroplasty technique. Study eligible patients with painful osteoporotic compression fractures will be randomized (2:1) to vertebroplasty with Cortoss (treatment group) or PMMA (control group), respectively. Patients will not be told which treatment they will receive (single blind study design). Safety and effectiveness will be determined by comparing the success rate of the treatment group to the success rate of the control group. Secondary endpoints will include Quality of Life, Patient satisfaction, evaluation of the patient's pain and function post-operatively compared to baseline, and maintenance of vertebral body height and alignment.

For the purposes of this study, vertebral augmentation, or vertebroplasty, is defined as a minimally invasive procedure utilizing manual instruments and radiological guidance to deliver an in-situ polymerizable material to stabilize a collapsed or fractured vertebral body. The goal is to alleviate pain caused by the fracture and enhance or prevent further deterioration of function.

This multi-center study will evaluate Cortoss for the augmentation of one or two vertebra(e), fractured as a result of osteoporosis, located between (and including) the levels of the sixth thoracic and the fifth lumbar vertebrae. A total of 243 patients will be enrolled at up to 19 sites. All subjects must have radiographic evidence of a vertebral body fracture due to osteoporosis. After complying with all eligibility criteria, subjects will sign an informed consent document and will be randomized into vertebroplasty treatment with Cortoss or PMMA (1:1 ratio). Patients will be followed for at least 24 months and recruitment is expected to take between 9 and 12 months. Visits and assessments are planned according to the time and events schedule.

What participants receive

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

  • Percutaneous Vertebral Augmentation of compression fracturesDevice

    Also called CORTOSS, a Bis-GMA composite material, a vertebral augmentation strengthening agent., PMMA, commercially available poly methyl methacrylate material, on-label for vertebral augmentation.

    Study eligible patients with painful osteoporotic compression fractures will be randomized to percutaneous vertebroplasty with CORTOSS (treatment group) or PMMA (active control group).

What is being measured

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

    Measured: 24 Months

  2. Maintenance or improvement in function (efficacy prong of primary endpoint) at 24 months compared to pre-treatment baseline using the Oswestry Disability Index (ODI)

    Measured: 24 Months

  3. Maintenance vertebral height and alignment (efficacy prong of primary endpoint) at 24 Months compared to 1-month post-vertebropalsty baseline radiographs

    Measured: 24 Months

  4. No device-related subsequent surgical intervention at study treated level

    Measured: 24 Months

Secondary outcomes (3)
  1. Maintenance or improvement in quality of life (secondary endpoint) at 24 months compared to baseline using the SF-12

    Measured: 24 Months

  2. Ambulatory status

    Measured: 24 Months

  3. Patient satisfaction

    Measured: 24 Months

Questions about this trial

What is this clinical trial studying?

A study testing Percutaneous Vertebral Augmentation of compression fractures in people with Spinal Fractures, run by Orthovita d/b/a Stryker at 18 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 11 inclusion and 16 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 15 Oct 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 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.

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?

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?

Early and sustained decrease in pain (efficacy prong of primary endpoint) at 24 months compared to pre-treatment baseline using the Visual Analog Scale (VAS) (time frame: 24 Months). The study lists 4 primary outcomes in all. 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 15 Oct 2008.
