Full Study Name

A Prospective, Randomized, Controlled, Single-Blind, Dose-Finding, Multicenter, Parallel Group Study of the Safety and Efficacy of KUR-113 Bone Graft (TGplPTH1-34 in Fibrin) Versus Local Autograft for the Treatment of Patients Undergoing Single-Level Transforaminal Lumbar Interbody Fusion (The STRUCTURE Study) (IRB no. 0000847)


This study focuses on individuals who have been diagnosed with degenerative disc disease and require surgery to prevent the damaged disc from moving (which would decrease associated pain). During this type of surgery, the damaged disc is removed, and the vertebras are fused together by inserting a device with a bone graft to help stabilize the spine during the healing process (a procedure called spinal fusion).
The purpose of this study is to examine the safety and effectiveness of an investigational drug called KUR-113 Bone Graft (compared to a local autograft) as a possible treatment for patients with degenerative disc disease who will undergo surgery for spinal fusion. Researchers aim to determine how well the drug works, which dose is most effective, and how safe it is compared to standard surgical treatment using a local graft.
