Study summary

This study has been designed to compare the safety and effectiveness of the CornerLoc™ SI Joint Stabilization System to intra-articular sacroiliac joint steroid injection in patients with refractory sacroiliac joint dysfunction.

Read the detailed description

Randomized, multicenter, open-label, randomized design to compare CornerLoc Allograft-based Sacroiliac Joint Stabilization System to Intra-articular Sacroiliac Joint Steroid Injection. Within the initial phase, referred to as the Randomized Phase, the primary determination of efficacy and safety will be 6-months following the study procedure. The analysis will be based on the randomization assignment. In the second phase of the study, referred to as the Cross-over Phase, patients who fail to respond to the randomized treatment assignment will be permitted to receive the non-randomized treatment. The basis of the sample size and hypothesis testing for this clinical investigation will be based on the Randomization Phase.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Study arms

  • Active comparator
    CornerLoc SI Joint Stabilization Group

    Patient will receive the CornerLoc minimally invasive SI Joint Stabilization procedure. This procedure will be performed in an outpatient surgery center under local sedation or general anesthesia, and normally takes around 45 minutes. During the procedure, the physician will make two small incisions in the patient's lower back to access the SI joint, and place four small cadaveric bone grafts into the SI joint to help stabilize the SI joint.

    Device: CornerLoc SI Joint Stabilization Procedure

  • Active comparator
    SI Joint Steroid Injections Group

    Patient will receive an injection of steroid medication directly into their SI joint. The area around the SI joint will be numbed with an injection of local anesthetic and then ultrasound guidance will be used to guide the needle of steroid medication directly into the SI joint. This procedure will be performed in the physician's office or an outpatient surgery center, and normally takes around 30 minutes.

    Drug: Intra-articular Sacroiliac Joint Steroid Injection

What researchers measure

Primary outcomes

  1. Efficacy of sacroiliac joint stabilization using the CornerLoc procedure in the treatment of sacroiliac joint pain by evaluating the efficacy responder rate versus an intra-articular steroid injection.

    The efficacy responder rate is defined as the percentage of subjects who experience at least a 50% improvement in overall pain, as measured by the Numeric Rating Scale (NRS) for Pain, from Baseline to the 6-Month Visit. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).

    Time frame: 6 months

Secondary outcomes

  1. Quality of life improvement from baseline to each follow-up visit.

    PROMIS-29; Patient Reported Outcomes Measurement Information System (PROMIS) instruments contain a fixed number of items from seven PROMIS domains: depression; anxiety; physical function; pain interference; fatigue; sleep disturbance; and ability to participate in social roles and activities. The seven domains cover the most relevant areas of self-reported health for the greatest majority of people with chronic illness. The PROMIS-29, a generic health-related quality of life survey, assesses each of the 7 PROMIS domains with 4 questions. The questions are ranked on a 5-point Likert Scale. There is also one 11-point rating scale for pain intensity.

    Time frame: 6 months

  2. Clinical improvement based on pain from baseline to each follow-up visit.

    Numeric Rating Scale for Pain: The Numeric Rating Scale for Pain is a measure in which individuals rate their pain on an eleven point numerical scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain). The patient will be asked to point to the number on the Numeric Rating Scale that best represents intensity of pain.

    Time frame: 6 months

  3. Clinical improvement of low back pain from baseline to each follow-up visit.

    Oswestry Disability Index (ODI): The Oswestry Disability Index (also known as the Oswestry Low Back Pain Disability Questionnaire) is a tool for evaluators used to measure a patient's permanent functional disability. Each question is scored on a scale of 0-5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). A higher score on the ODI indicates a more severe disability caused by lower back pain.

    Time frame: 6 months

  4. Clinical improvement in balance and risk for falls from baseline to each follow-up visit.

    Timed Up and Go" (TUG) Test: This test measures the time for a subject to get up from a chair walk 3 meters, turn around and return to the chair and sit. Time is measured in minutes and seconds. An average of two tests is used. The shorter average time indicates clinical improvement.

    Time frame: 6 months

  5. Clinical improvement from baseline to each follow-up visit.

    Zurich Claudication Questionnaire (ZCQps); The Zurich Claudication Questionnaire quantifies severity of symptoms, physical function characteristics, and patient's satisfaction after treatment. The scale relates to symptoms over the past month. There are 12 questions for all patients, and a further 6 questions to measure treatment outcome. Decreasing scores indicates clinical improvement

    Time frame: 6 months

  6. Clinical improvement based on use of medications from baseline to each follow-up visit.

    Medication Use: All medications that are used prior to and during their participation in this study will be documented and monitored.

    Time frame: 6 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 15, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
