Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - OsteoAdapt SP
Other interventions - Local Autograft

Experimental: Low Dose OsteoAdapt SP (0.8 mg/cc AMP2/OsteoAdapt SP) - Participants will receive a Transforaminal Lumbar Interbody Fusion with OsteoAdapt SP "Low Dose (0.8mg/cc AMP2/OsteoAdapt SP)" inside the interbody fusion cage with the availability of having local autograft placed anterior/lateral to the cage within the disc space.

Experimental: High Dose OsteoAdapt SP (2.0 mg/cc AMP2/OsteoAdapt SP) - Participants will receive a Transforaminal Lumbar Interbody Fusion with OsteoAdapt SP "Low Dose (2.0 mg/cc AMP2/OsteoAdapt SP)" inside the interbody fusion cage with the availability of having local autograft placed anterior/lateral to the cage within the disc space.

Active Comparator: Control (Standard of Care - Autograft/Mineralized Allograft) - Patients will follow standard of care Transforaminal Lumbar Interbody Fusion in which local autograft will be placed inside the interbody fusion cage with the availability of mineralized, frozen, banked, allograft to be placed anterior/lateral to the cage.


Treatment: Devices: OsteoAdapt SP
OsteoAdapt SP is a combination of AMP2 protein bound to an osteoconductive carrier matrix, ReBOSSIS-J. OsteoAdapt SP is a combination of AMP2 protein bound to an osteoconductive carrier matrix, ReBOSSIS-J.
AMP2 is a recombinant variant of a naturally occurring human protein, rhBMP2, that has been modified to allow very tight binding to ß-TCP and similar ceramics. AMP2 is osteoinductive, meaning that the protein stimulates new bone formation at the site of implantation through the same intracellular signaling process as rhBMP2.
ReBOSSIS-J is a synthetic, resorbable bone void filler. ReBOSSIS-J is flexible and can easily fill defects of different sizes using appropriate amounts of the device.
The combination product, OsteoAdapt SP, is hydrated at the time of surgery with saline and placed into the interbody fusion cage.

Other interventions: Local Autograft
For control arm, local autograft will be utilized inside the interbody cage.
