Study summary

The purpose of this clinical trial is to compare the efficacy and safety of this investigational device with autologous iliac bone graft (ICBG) in patients who are deemed to require bone fusion through spinal fixation at two levels (ALIF or OLIF) due to disc degeneration or spinal deformity in the lumbosacral spine (L2-S1) for intervertebral support and correction with the aim of stabilizing the spine.

Terms in these criteria, in plain language(10)

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Primary endpoints of efficacy

    Bone fusion status 12 months visit after index procedure The success rate of bone fusion at the 12-month visit after the index procedure will be evaluated. Imaging evaluations will be performed at baseline, after the index procedure (to discharge), at 3, 6, and 12 months (CT scan will be performed at baseline, 6, and 12 months only), and imaging evaluation for the primary efficacy endpoint will be performed by the core laboratory at the 12-month visit. Primary endpoints

    Time frame: 12 months

  2. Primary endpoints of safety

    Incidence of Adverse Device Effects in both groups up to 12 months post index procedure. To evaluate the rate of subjects experiencing any adverse device effects in both groups that occurring up to 12-month visit after the index procedure.

    Time frame: 12months

Secondary outcomes

  1. Change in disc height at the 12-month visit compared to the measurements taken within 14 days after the index procedure.

    The height of the intervertebral disc measured by x-ray in the standing position. The calculation method uses (anterior disc height + central disc height + posterior disc height) divided by the anteroposterior diameter of the vertebral body. Preoperative measurements are conducted to understand the subject's pathological condition. 2) Change of General health condition at follow-

    Time frame: From 14 days after the index procedure to 12months

  2. Change of General health condition at follow-ups from baseline at 12months.

    Medical Outcomes Study 36-ltem Short Form Health Survey (SF-36) was used to assess the general health status of the subjects. The results of SF-36 can be summarized into two components: physical element summary (PCS) and mental element summary (MCS).

    Time frame: From baseline to 12months

  3. Change of OSWESTRY DISABILITY INDEX (ODI) at follow-ups from baseline at month 12.

    Using the ODI, calculate and evaluate each score for the 10 sections (pain intensity, self-care, raising the object, etc.)

    Time frame: From baseline to 12Months

  4. Change of Lower back pain at follow-ups from baseline at 12months

    The numerical rating scale (Numerical Rating Scale (NRS)) used to evaluate lower back pain using a score of 0-10.

    Time frame: From baseline to 12months

  5. Change of Pain in lower extremities (leg pain) at follow-ups from baseline at 12months

    The numerical rating scale (Numerical Rating Scale (NRS)) used to evaluate leg pain using a score of 0-10

    Time frame: From baseline to12months

  6. Required time until bone fusion

    Assess the time required for bone fusion through imaging evaluation (CT scan, X-ray examination)

    Time frame: From baseline to12 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 Sep 9, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
