A Clinical Study to Evaluate Safety and Performance of PEEK-OPTIMA™ HA Enhanced Interbody Cages in the Lumbar Spine

Study Purpose

The purpose of this trial is to collect clinical outcomes including radiographic and CT outcomes in patients who undergo interbody spinal fusion using the EVOS Lumbar Interbody System.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This prospective, non-comparative, multi-center, post-market trial will evaluate the safety and efficacy of the PEEK-OPTIMA™ HA Enhance Interbody Cages System

  • - EVOS- HA in patients suffering from degenerative disc disease and spondylolisthesis in the lumbar spine.
The trial will capture clinical outcomes, radiographic and CT outcomes over a 24 month period post operatively. Two centers will be involved in the recruitment of 30 patients. All patients will be drawn from clinics which focus on this type of treatment.
