A Study to Assess Adverse Events and Change in Disease Activity of Intramuscular AGN-151586 Injection in Toxin-Naïve Adult Participants With Glabellar Lines

• Status: Not yet recruiting
• Trial end date: 2023-01-12
• Target enrollment: 0
• Participant gender: All

Summary

Facial lines that develop from repeated facial expression, such as glabellar lines (GL), are typically treated by selectively weakening specific muscles with small quantities of botulinum toxin. AGN-151586 is an investigational product being developed for the treatment of GL. The purpose of this study is to evaluate the safety and efficacy of AGN-151586 for the treatment of GL in toxin-naïve participants with moderate to severe GL.

This is a 12 week study in which eligible subjects will be enrolled into the study containing 2 treatment periods, double-blind period and open-label period. Participants are randomly assigned to receive AGN-151586 or placebo. There is 1 in a 4 chance that participants will receive placebo. Around 300 adult participants with moderate to severe GL will be enrolled in the study in approximately 15 sites.

Participants will receive either AGN-151586 or Placebo administered as 5 intramuscular injections to the glabellar complex on Day 1. Participants meeting retreatment criteria may receive an open-label treatment of AGN-151586 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.

Criteria

Inclusion Criteria:

• Participants must be able to accurately assess their facial lines without the use of eyeglasses (contact lens use is acceptable).

• Participant must have moderate or severe Glabellar Lines at maximum frown as assessed by both the investigator and participant using the Facial Wrinkle Scale (FWS) at Screening and Baseline Day 1 visit.

Exclusion Criteria:

• Uncontrolled systemic disease.

• Participants must not have a history of any use of botulinum neurotoxin of any serotype for any indication (including any investigational botulinum neurotoxin product).

• Presence or history of any medical condition that may place the participant at increased risk following exposure to AGN-151586 or interfere with the study evaluation, including:

• Diagnosed myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other significant disease that might interfere with neuromuscular function

• History of facial nerve palsy

• Infection or dermatological condition at the treatment injection sites

• Marked facial asymmetry, dermatochalasis, deep dermal scarring, excessively thick sebaceous skin, excessively photodamaged skin, or the inability to substantially lessen facial lines even by physically spreading them apart

• Any eyebrow or eyelid ptosis at screening or Baseline Day 1 visit as determined by the investigator

• History of known immunization to any botulinum neurotoxin serotype.

• Tattoos, jewelry, or clothing which obscure the glabellar area and cannot be removed.

• Anticipated need for surgery or overnight hospitalization during the study.

• History of surgical procedures on forehead and/or periorbital areas or affecting these areas including any lifting procedure (e.g., rhinoplasty, facial lift, suture lift, thread lift, brow lift, eyelid and/or eyebrow surgery).

• History of periorbital, mid-facial, or upper-facial treatment with semi permanent or permanent soft tissue fillers (e.g., poly-L-lactic acid, polyalkylimide, polymethylmethacrylate, polytetrafluoroethylene, and silicone), synthetic implantation and/or autologous fat transplantation.

• Known active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or subjects with a positive polymerase chain reaction (PCR) test in the past 14 days prior to Baseline Day 1 who are asymptomatic.

• Female subject who is pregnant or breastfeeding, and is considering becoming pregnant or donating eggs during the study or for approximately 30 days after the last dose of study drug or until the end of study, whichever is longer.

• Participant who has been treated with any investigational drug within 30 days of the drug prior to the first dose of study drug or is currently enrolled in another clinical study or was previously enrolled in this study.

• Anticipated need for treatment with botulinum neurotoxin of any serotype for any reason during the study (other than study drug).
