Effects and Safety of Epidural PDRN vs. Placebo

This is a single-center, randomized, double-blind clinical study to assess the clinical application and outcomes with epidural PDRN versus Normal saline injection in patients with spinal stenosis.

Prospective Multicenter Non-randomized Single Arm Clinical Trial to Evaluate the Safety and Efficacy of e-PTFE Grafts Inner Surface-treated With Paclitaxel as an Access for Hemodialysis in Patients With End-stage Renal Disease.

This prospective, multicenter, non-randomized, single-arm Clinical trial aims to evaluate the safety and effectiveness of the use of paclitaxel-coated arteriovenous graft (AVG) on the inner wall of ePTFE graft, which is designed to reduce neointimal hyperplasia that causes stenosis and thrombosis after implantation of AVG.
