Brief Summary

A Phase 1, Open-Label, Prospective, Dose-finding Clinical Trial for Evaluation of Safety and Tolerability of Intramuscular Injections of CLZ-2002 for the Treatment of Subjects with Charcot-Marie-Tooth type 1(CMT 1)

Detailed Description

This study is the First In Human (FIH) clinical trial for evaluating the safety and tolerability of IM injections of CLZ-2002 in patients with Charcot-Marie-Tooth disease (CMT) Type 1.

CLZ-2002 is the allogeneic mesenchymal stem cell-derived Neuronal Regeneration Promoting Cells. These cells are Schwann cell-like cells differentiated from tonsillar mesenchymal stem cells. CLZ-2002 helps the remyelination of the damaged peripheral nerves by restoring the myelin sheaths. It also induces the nerve regeneration and myelination pathways in the sciatic nerve and restores abnormal muscle tissues in Charcot-Marie-Tooth disease type 1 (CMT1).
