A Study to Assess Adverse Events and Effectiveness of HAC 20L Injections in Adult Participants for the Treatment of Nasolabial Folds

Overview

Nasolabial folds (NLF) are the two skin folds that run from each side of the nose to the corners of the mouth. Prominent NLFs distort the contour of the midface, giving a fatigued and aged appearance. Soft tissue fillers can be used to reduce the depth of NLFs and restore a more youthful appearance. The purpose of this study is to evaluate how safe and effective HAC 20L is in the correction of moderate to severe NLF in adult participants. HAC 20L is an investigational drug being developed for the treatment of NLF. There are 2 cohorts in this study. In each cohort participants are assigned to either the treatment group or no-treatment control group. There is a 1 in 3 chance that participants will be assigned to the no-treatment control group. Around 75 adult participants with moderate to severe NLF will be enrolled in the study at approximately 20 sites worldwide. Participants in the treatment group will receive an injection of HAC 20L to the NLF on Day 1 in Cohort 1 and Cohort 2 with the option of re-treatment after completion of Month 12 visit. The control group will receive no treatment but will be offered an optional HAC 20L treatment after 6 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be examined by completing effectiveness questionnaires by the subjects, evaluating investigator (EI) and central reviewers as well as monitoring safety assessments such as vital signs, blood tests, injection site responses and adverse events.
