A Study of [89Zr]-Oxine-NCR100 Injection for the Cellular Distribution

Phase 1Not Yet RecruitingNCT07139431

Nuwacell Biotechnologies Co., Ltd.6 enrolled

Overview

This clinical study is to evaluate the biodistribution of \[89Zr\]-Oxine-NCR100 injection in subjects with knee osteoarthritis after local injection and the kinetic behavior characteristics of zirconium-labeled cells at the injection site and various organs or tissues. It is a single-dose, open-label study in adult KOA subjects.

Knee osteoarthritis(KOA) is a kind of degenerative joint disease characterized by chronic inflammation loss of articular cartilage and subchondral bone remodeling. This clinical trial aims to evaluate the biodistribution of 89Zr-labeled human pluripotent stem cell derived mesenchymal stromal cells (\[89Zr\]-Oxine-NCR100) injection in subjects with knee osteoarthritis after local injection and the kinetic behavior characteristics of the zirconium-labeled cells at the injection site and in various organs or tissues.
