About this study

Official title: AttraX® Putty vs. Autograft in eXtreme Lateral Interbody Fusion (XLIF®): A Prospective Randomized Single-Center Evaluation of Radiographic and Clinical Outcomes

The objective of this study is to evaluate the clinical success of AttraX Putty as a bone graft substitute for autograft in XLIF procedures.

Read the detailed description

This is a single-center, prospective, randomized study. Subjects will be recruited from patients already under the Investigator's care who are indicated for XLIF with iliac crest bone graft (ICBG) autograft or AttraX Putty. To minimize bias, all consecutive patients at a given investigational site who meet eligibility requirements will be asked to consent to participate in the study whereby the biologic (ICBG autograft or AttraX Putty) will be randomly assigned. All subjects will be followed for 24 months following surgery to quantify the clinical and radiographic improvements of each biologic compared to baseline and in comparison with each other.

Being tested
AttraX Putty, Iliac Crest Bone Graft (ICBG)
Keywords
Degenerative disc disease, Lumbar spine

Questions about this trial

What is this clinical trial studying?

A study testing AttraX Putty and Iliac Crest Bone Graft (ICBG) in people with Degenerative Conditions of the Lumbar Spine, run by NuVasive at 1 site in Brazil.

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 8 inclusion and 17 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: finished, as of the sponsor's last update on 22 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The number and percentage of subjects with radiographically apparent fusion 24 months. (time frame: 24-months). 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 22 Dec 2025; AzTrials last refreshed its copy on 3 Nov 2026.
