About this study
Official title: Clinical Study Protocol for the Investigation of the Kineflex Spinal System - a Pivotal Study in Continued Access Stage
The Kineflex Spinal System is no worse than the Charite Spinal System in patients with single level degenerative disc disease at L4/5 or L5/S1.
Read the detailed description
The Kineflex disc is a 3-piece modular design consisting of 2 cobalt chrome molybdenum (CCM) end-plates and a fully articulating CCM core. The system is available in 3 foot print sizes.

Questions about this trial
What is this clinical trial studying?
A study testing Lumbar Artificial Disc and Charite Artificial Disc in people with Degenerative Disc Disease, run by SpinalMotion at 21 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 8 inclusion and 32 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 13 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 21 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?
The study was stopped early (reason given: Economic and business reasons). 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?
Improvement in Oswestry Low Back Pain Disability Score at 24 months compared with baseline; no revision removal, supplemental fixation or device related reoperations and no major adverse event as defined by the study protocol (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 13 Sep 2013; AzTrials last refreshed its copy on 7 Nov 2026.
