Summary

This trial is testing a new treatment using fluid from around a baby in the womb to help people with chronic back pain who haven't found relief from other treatments. The fluid reduces inflammation and helps repair nerves, which can ease pain and improve daily function.

Who is the study for?
This trial is for adults over 18 with chronic leg pain due to lumbar spinal stenosis, who haven't improved after at least 3 months of non-invasive treatments like physical therapy or medication. They must be able to read English and complete questionnaires, have not had a steroid injection in the past 90 days, and can't join if they're pregnant, have allergies to the injections used, bleeding disorders, recent heart attacks, history of certain neurological diseases or spinal surgeries.
What is being tested?
The study compares two treatments for chronic back-related leg pain: an epidural injection of amniotic fluid allograft (hAF), which has regenerative properties and may reduce inflammation without severe side effects; versus dexamethasone sodium phosphate (a corticosteroid). The goal is to see which treatment better reduces pain and disability without leading to surgery.
What are the potential side effects?
Dexamethasone might cause issues like increased blood sugar levels or risk of infection. Amniotic Fluid Allograft is expected to have fewer side effects but could potentially include mild reactions at the injection site.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Transforaminal epidural Amniotic Fluid injectionExperimental Treatment1 Intervention
Using fluoroscopic guidance, a lumbosacral epidural injection will be performed. 2-5cc of 1% lidocaine will be injected into the skin and subcutaneous tissue to anesthetize the skin and subcutaneous structures over the site of planned entry to the neural foramen. A 22 or 25 g Whitacre needle (3.5-7") will be used to access the epidural space using the sub-pedicular or infraneural transforaminal approach, depending on individual anatomy at the discretion of the treating physician. Needle tip position will be confirmed using anterior-posterior and lateral fluoroscopic views as well as with injection of a standard 1-3 mL aliquot of omnipaque 180 (Iohexol) (GE Healthcare) contrast material during live fluoroscopy to confirm epidural flow of contrast and to rule out an intravascular injection. Then 3 mL of Amniotic Fluid will be injected through the spinal needle for unilateral symptoms, for a total injection volume of 3 mL in both groups.
Group II: Transforaminal epidural dexamethasone injectionActive Control1 Intervention
Using fluoroscopic guidance, a lumbosacral epidural injection will be performed. 2-5cc of 1% lidocaine will be injected into the skin and subcutaneous tissue to anesthetize the skin and subcutaneous structures over the site of planned entry to the neural foramen. A 22 or 25 g Whitacre needle (3.5-7") will be used to access the epidural space using the sub-pedicular or infraneural transforaminal approach, depending on individual anatomy at the discretion of the treating physician. Needle tip position confirmed using anterior-posterior and lateral fluoroscopic views as well as with injection of a standard 1-3 mL aliquot of omnipaque 180 (Iohexol) (GE Healthcare) contrast material during live fluoroscopy to confirm epidural flow of contrast and to rule out an intravascular injection. 1 mL of dexamethasone sodium phosphate (10 mg/mL) combined with 2 mL of sterile water will be injected through the spinal needle for unilateral symptoms, for a total injection volume of 3 mL in both groups.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Lumbar Spinal Stenosis often focus on reducing inflammation, protecting nerve tissues, and promoting regeneration. Corticosteroid injections, for example, work by reducing inflammation around the spinal nerves, thereby decreasing pain and swelling. The investigational treatment hAF (human Amniotic Fluid) offers neuro-protective and regenerative properties, with high levels of anti-inflammatory cytokines that help reduce inflammation and support nerve regeneration. These mechanisms are crucial for patients as they aim to alleviate pain, improve function, and potentially avoid surgical interventions.
