Randomized Controlled Trial Multicenter StudyA phase I/II study for intrathecal administration of recombinant human hepatocyte growth factor in patients with acute spinal cord injury: a double-blind, randomized clinical trial of safety and efficacy.
Spinal cord injury (SCI) is an abrupt traumatic injury that leads to permanent functional loss, and no practical treatment is available. We have developed pharmaceutical recombinant human hepatocyte growth factor (KP-100), and its efficacy for SCI has been verified using animal models. The purpose of this study was to evaluate the safety and efficacy of intrathecal KP-100 administration for SCI patients in the acute phase. ⋯ In the subset of subjects with Frankel grade A, the proportions of subjects who gained at least 1 point on their lower-extremity motor scores were 33.3% (5/15) and 6.3% (1/16) in the KP-100 and placebo groups, respectively (p = 0.083). Therefore, KP-100 has the potential to be useful and beneficial for SCI patients during the acute phase. However, this was a phase I/II trial and did not definitely address the question of efficacy; a larger phase III trial would be required to assess the efficacy.
