Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Autologous Incubated Macrophages (ProCord) is being developed as a therapy for acute, complete spinal cord injury (SCI). The therapy is intended to reverse the loss of motor and sensory function.

Following non-CNS tissue injury, macrophages quickly arrive on the scene, where they clean up cell debris, secrete different molecules thus promoting a controlled inflammatory reaction that forms the first phase of the wound healing process. While this process occurs in most tissues, including peripheral nerves, it does not occur in the CNS, where macrophages and other immune cells are relatively rare, and their activities curtailed by a biochemical mechanism known as "immune privilege."

In animal studies, it appears that incubated macrophages circumvent the immune privilege, thus supporting the regrowth of axons through the injury site and enabling the recovery of neurological function. The concept derives from the pioneering research of Prof. Michal Schwartz at the Weizmann Institute of Science.
