Note: WOCBP including peri-menopausal women who have had a menstrual period within 1 year prior to surgery have to have a negative pregnancy test before entering in the study.
  • Any other psychosocial, mental and physical condition which, in the opinion of the investigator, could interfere with the trial conduct, the patient's compliance or influence interpretation of the results.

About this study

Official title: A Proof-of-concept Study With NVDX3, an Osteogenic Implant of Human Allogenic Origin, in the Treatment of Low Grade Degenerative Lumbar Spondylolisthesis by Interbody Spine Fusion in Adults.

Prospective, single arm, single-center clinical study to test NVDX3 in patients suffering from low grade one level degenerative lumbar (L1 - S1) spondylolisthesis. NVDX3 will be implanted during a single surgical intervention.

Read the detailed description

This is a prospective, single arm, single-center PoC study in adult patients, suffering from a degenerative lumbar (L1-S1) spondylolisthesis, treated by spondylodesis in which NVDX3, an osteogenic implant from human allogeneic origin is used. The screening and implant surgery visits will be used as the reference timepoint respectively for the clinical and the radiological efficacy outcome evaluations.

As per standard of care, patients with DLS are followed up to 12 months post-intervention. In the context of this trial, patient safety and IMP efficacy will be followed up to 24 months post-implant surgery.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing NVDX3 in people with Degenerative Lumbar Spondylolisthesis, run by Novadip Biosciences at 1 site in Luxembourg.

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 9 inclusion and 18 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: under way, not looking for participants, as of the sponsor's last update on 24 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 Luxembourg. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Primary Safety Endpoint (time frame: Up to 24 months post implant 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 24 Dec 2025.
