Study summary

Lumbar discectomy and injection of purified cellular bone marrow concentrate or lumbar discectomy only

Read the detailed description

In order to find a regenerative treatment for back pain from DDD, cell based therapies have become of increasing interest. Recent clinical studies have shown promising improvement in pain and disc hydration, thus indicating a regenerative effect.

The use of mesenchymal stem cells for regeneration of degenerated connective tissue of mesenchymal origin has proven efficient in multiple recent studies. However, the acquisition of mesenchymal stem cells (MSC) is always an extensive procedure requiring either enzymatic or genetic manipulation of acquired tissues. Thus, the use of these MSCs is highly controversial and raises concerns in terms of patient safety.

One of the most commonly used sources for MSCs is bone marrow tissue. Even when not manipulated, these tissues already contain a significant amount of mesenchymal stem cells and growth factors. Therefore, they are used for regenerative treatments of multiple degenerative musculoskeletal diseases.

This is an exploratory pilot study which aims to compare patient outcomes between two treatments approaches for DDD that are currently being used in clinic. While micro- discectomy is the standard of care for DDD, micro-discectomies with autologous bone marrow cell injections have been used in clinic in the past year. The goal of this study is to determine if the bone marrow injection group is superior compared to the control group (state of the art micro-discectomies) in enhancing degenerative disc recovery and improving or preventing back pain.

Study population

Patients with symptomatic lumbar disc herniation and discogenic back pain who meet the inclusion criteria may be eligible for this procedure.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male or female patients ≥18 years of age
  2. Radiologically (MRI) confirmed diagnosis degenerative disc disease of the lumbar spine and/or lumbar disc herniation
  3. Unresponsive to conservative/non-operative treatment for >3 months
  4. Psychosocial, mental and physical ability to understand and to adhere to this protocol, especially adhering to the visit schedule follow-ups, and observe treatment plan
  5. Signed and dated document prior to any study-related procedures indicating that the patient has been informed of all pertinent aspects of the trial study-related procedures

Exclusion criteria

Exclusion Criteria:

  1. Pregnant or breastfeeding patients
  2. Active
  3. Active chronic or acute infection
  4. disorder that impacts the lumbar spine (Ankylosing spondylitis, lupus eg.)
  5. Acute Episode or major mental illness
  6. Major cognitive impairment causing to inability to understand
Terms in these criteria, in plain language(3)

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.

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.

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.

Interventions

  • ProcedureAutologous bone marrow aspirate injected intradiscal after microdiscectomy

    Harvested from SI-joint, 2-5ml BMA is injected in the discectomy defect.

  • ProcedureDiscectomy only

    Transflaval discectomy with or without the use of a microtube (according to surgeons' preference).

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 Dec 21, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
