BMAC + Allograft vs BMP-2 for Spinal Fusion
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares different methods to help bones fuse in spinal fusion surgery patients. Researchers are examining bone marrow concentrate mixed with donor bone (allograft), a protein called BMP-2, and the usual method using the patient's own bone (autograft). They aim to determine which option promotes better bone healing and improves quality of life. Individuals who have not undergone spinal fusion surgery before and have tried at least six weeks of other treatments without success may qualify for this trial. As an unphased trial, this study provides a unique opportunity to explore innovative treatments that could enhance recovery and quality of life.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you use drugs that might interfere with bone or soft tissue healing, like chronic systemic steroids.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that Bone Marrow Aspirate Concentrate (BMAC) is safe for use in spine surgery. Studies have found that BMAC is usually well-tolerated, with few complications at the extraction site.
For Recombinant Human Bone Morphogenetic Protein-2 (BMP-2), research indicates it promotes bone growth. However, some patients have experienced side effects, such as swelling at the application site.
Specific safety information for using BMAC with allograft is not available, but BMAC alone is considered safe in spine surgeries. The FDA has approved BMP-2 for certain uses, suggesting it is generally safe. It is important to consult a healthcare provider about any concerns before joining a trial.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the BMAC + Allograft treatment for spinal fusion because it combines bone marrow aspirate concentrate (BMAC) with allograft bone chips, potentially enhancing bone healing and fusion. This method is unique because BMAC is rich in stem cells and growth factors, aiming to promote better bone regeneration compared to traditional options like autografts or BMP-2. Additionally, the use of the Harvest SmartPrep® system to concentrate BMAC may improve the efficiency and effectiveness of the treatment, offering an innovative approach to spinal fusion surgery.
What evidence suggests that this trial's treatments could be effective for spinal fusion?
Research has shown that both BMAC with allograft and BMP-2 are promising options for spinal fusion surgery. In this trial, participants will receive either BMAC with allograft or BMP-2. Studies have found that BMAC with allograft can be as effective as using the patient's own bone. This method is safe and may reduce treatment costs for patients with complex health conditions. Meanwhile, BMP-2, which aids bone growth, has also proven effective for spinal fusion. It has successfully fused bones and improved patient outcomes. Both treatments offer potential benefits for those needing spinal fusion surgery.23678

Are You a Good Fit for This Trial?
This trial is for adults over 18 needing elective spinal fusion surgery, who have tried non-surgical treatments for at least 6 weeks. Candidates should not be pregnant, have a BMI over 40, or suffer from certain bone diseases or allergies to titanium. Prior lumbar surgeries may disqualify them.Inclusion Criteria

Trial Overview
The study compares three methods of spinal fusion: using the patient's own bone graft (autograft), combining bone marrow concentrate (BMAC) with allograft (donor tissue), and using recombinant human BMP-2. It aims to determine which method is safest and most effective in improving quality of life.

Experimental Treatment
Active Control
A total of 60, 120, or 180 mL of BMA to be aspirated. BMA is then placed into the Harvest SmartPrep® Bone Marrow Concentrate (BMAC) system and concentrated to a final volume of 10, 20, or 30 mL. The BMAC will then be combined with packed allograft cancellous bone chips using the Harvest Graft Delivery Pack. The allograft bone will be obtained routinely from the bone bank in the operating suite. If using Harvest Graft Delivery Kit, the BMAC dosing estimate is as follows (BMAC to graft ratio will be 1:1): * 1-level fusion: 10 cc of BMAC from 60 cc of BMA (roughly 10 cc of graft) * 2-level fusion: 20 cc of BMAC from 120 cc of BMA * 3-level fusion: 20 cc of BMAC from 120 cc of BMA * 4-level fusion: 180 cc kit * 5-level fusion: 240 cc kit If not using Harvest Graft Delivery Kit: * Volume of BMAC will be slightly increased (some BMAC will not get directly into hydrating the graft as the BMAC would get lost in the hydration process and left in mixing bowls).
12 mL BMP will be applied at the surgical site of the interbody fusion using a collagen sponge following manufacturer's directions. The BMP kit use per level is as follows: * 1 Level Fusion: Extra small kit (1.4 cc) * 2 Level Fusion: Small Kit (2.8cc) * 3 Level Fusion: (4.2 cc) * 4 Level Fusion: Medium Kit (5.6cc) * 5 Level Fusion: (7.0 cc)
As per standard of care, the control group will receive 15cc - 45 cc of allograft with autograft and bone marrow aspirate at each level. The iliac crest is the common donor site for autograft. Using the standard technique for anterior lateral fusion, the bone graft will be laid onto the desired site of fusion.
Autograft is already approved in United States, European Union for the following indications:
- Lumbar fusion
- Spinal fusion
- Bone defects
- Fractures
- Delayed union
- Nonunion
- Orthopedic trauma
- Bone reconstruction
- Spinal fusion
- Lumbar fusion
