Study summary

Among existing surgical techniques, spinal fusion is considered as the gold standard to treat a broad spectrum of degenerative spine disorders, including spondylolisthesis and scoliosis, with regard to pain reduction and functional improvement. However, pseudarthrosis and failure to relieve low back pain are unfortunately still frequent, irrespective of the type of procedures and grafts used by the surgeon.

The present Phase 2a study aims at demonstrating the safety and efficacy of ALLOB®, a proprietary population of allogeneic osteoblastic cells, in lumbar spinal fusion.

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

  • Ability to provide a written, dated, and signed prior to any study related procedure, and to understand and comply with study requirements
  • Symptomatic degenerative disc disease of the lumbar spine requiring a single level lumbar fusion (L1-S1)
  • Unresponsive to non-operative treatment for at least 6 months

Exclusion criteria

Exclusion Criteria:

  • Lumbar disc disease requiring treatment at more than one level
  • Previous failed fusion at the involved lumbar level
  • Local active or latent infection at the involved lumbar level
  • Positive serology for , ,
  • Current or past medical disease that could interfere with the evaluation of the safety and efficacy, as judged by the investigator
Terms in these criteria, in plain language(4)

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
