Brief Summary

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

Nasolabial folds augmentation is possible through dermal filler and botulinum toxin, however, safety issues are existed as well as efficacy. Therefore, there is a need for a safer procedure for nasolabial folds correction. This study (Project No. TPX-121) assesses the safety of allogeneic fibroblasts (TPX-115) on nasolabial folds. The safety endpoint is dose-limiting toxicity (DLT). In addition, exploratory endpoints are the improvement of nasolabial folds in Wrinkle Severity Rating Scale (WSRS) at week 4 and 12, change in WSRS and Wrinkle Severity Scale (WSS) at week 4 and 12, and overall appearance improvement rate in Global Aesthetic Improvement Scale (GAIS) at week 4 and 12.
