A Phase III, Multicentre, Double-blind, Randomised, Placebo-controlled, Parallel Group Study to Evaluate the Efficacy and Safety of a Single Dose of IPN10200 in the Improvement of Moderate to Severe Glabellar Lines in Adult Participants

Summary

The purpose of this study is to assess the effectiveness and safety of IPN10200 compared to placebo in the improvement of the appearance of moderate to severe glabellar lines in adult participants. Glabellar lines are wrinkle-like lines that appear between the eyebrows and can become more noticeable with age or repeated facial expressions. They may affect a person's appearance and confidence. In this study, all participants will receive a single injection of either IPN10200 or placebo (the study drug). There will be 3 periods in this study: * A screening period (up to 20 days) to assess whether the participant can take part, requiring at least 1 visit to the study centre. * A treatment period (Day 1) where all the eligible participants will receive a single injection of IPN10200 or placebo. * A follow-up period (52 weeks) where participants' health will be monitored, consisting of regular visits to the study centre and 1 telephone call visit. Participants will undergo health measurements and observation, including blood sampling, physical examinations, clinical evaluations and electrocardiograms (ECG: recording of the electrical activity of heart). They will also be asked to fill in questionnaires and keep a diary. Each participant will be in this study for up to 55 weeks. Participants may withdraw consent to participate at any time.
