The primary purpose of this study is to evaluate the safety of AGN-151586 over up to three treatments of the study drug to improve the appearance of glabellar lines. AGN-151586 is an investigational product being developed for the treatment of GL. Around 940 to 1100 adult participants with moderate to severe GL will be enrolled in the study in approximately 45 sites in the United States. This is an open-label study in which all participants will receive 5 intramuscular AGN-151586 injections to the glabellar complex on Day 1\. Participants meeting retreatment criteria may receive up to 2 additional doses of treatment during the study. Participants will attend regular visits during the study at a study site. The effect of the treatment will be checked by medical assessments, blood tests, telephone calls, questionnaires and checking for side effects.

Number of Participants With Adverse Events Timeframe: Day 1 (Baseline) to Day 126 An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of study drug. 2. Participants With Post-Baseline Potentially Clinically Important (PCI) Values for Systolic Blood Pressure Timeframe: Day 1 (Baseline) to Day 126 The number of subjects with at least 1 PCI post-baseline value during the study are reported. A post-baseline value was considered PCI if it met both the observed-value and the change-from-baseline criteria. 3. Participants With Post-Baseline PCI Values for Diastolic Blood Pressure Timeframe: Day 1 (Baseline) to Day 126 The number of subjects with at least 1 PCI post-baseline value during the study are reported. A post-baseline value was considered PCI if it met both the observed-value and the change-from-baseline criteria. 4. Participants With Post-Baseline PCI Values for Heart Rate Timeframe: Day 1 (Baseline) to Day 126 The number of subjects with at least 1 PCI post-baseline value during the study are reported. A post-baseline value was considered PCI if it met both the observed-value and the change-from-baseline criteria. 5. Participants With Post-baseline PCI Values in Temperature Timeframe: Day 1 (Baseline) to Day 126 Only the observed-value criterion (\\>= 38.3 C) was needed for temperature to be potentially clinically important (but must be more extreme than baseline, if baseline was present). 6. Participants With Post-baseline PCI Values in Electrocardiogram Parameters Timeframe: Day 1 (Baseline) to Day 126 12-lead resting ECGs will be recorded. Parameters include heart rate, PR interval, QT interval, QRS duration, and QT interval corrected using Fridericia's formula (QTcF). A post-baseline value is considered potentially clinically important if it meets either the observed-value or the change-from-baseline criteria (but must be more extreme than baseline if baseline is present). 7. Presence of Binding and Neutralizing Antidrug Antibodies to AGN-151586 Timeframe: Day 1 (Baseline) to Day 126 Blood samples for immunogenicity testing were collected from participants treated with AGN-151586 at predetermined timepoints. Collected samples were processed to yield serum for detection of binding and neutralizing antibodies to AGN-151586.
