Safety Study of TPX-121 on Nasolabial Folds

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.
