The purpose of this study is to find out about the effectiveness and safety of a single dose of corabotase (also known as IPN10200) compared to placebo works in participants with moderate to severe glabellar lines. 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 corabotase (the study drug) or placebo. 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 corabotase 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, and clinical evaluations. 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.
