A Study of OnabotulinumtoxinA X Injection in Adult Participants With Glabellar Lines

• Status: Recruiting
• Trial end date: 2022-06-13
• Target enrollment: 0
• Participant gender: Female

Summary

Hyperfunctional 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. BOTOX (onabotulinumtoxinA) was first approved for aesthetic treatment of glabellar lines in 2001 and is one of the most common nonsurgical procedures in aesthetic medicine. This is a proof-of-concept study to evaluate how safe this new OnabotA X formulation is in treating adult participants with GL .

OnabotA X is an onabotulinumtoxinA investigational product being developed for the treatment of moderate to severe glabellar lines (GL). This is a 180-day, open-label study to assess the safety of OnabotA X in adult subjects with moderate to severe GL. Around 90 participants will be enrolled in the study in approximately 5 sites in the United States.

Participants will receive one dose of OnabotA X administered as 5 injections on Day 1.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Criteria

Inclusion Criteria:

• Participant has sufficient visual acuity without the use of eyeglasses (contact lens use is acceptable) to accurately assess their facial lines.

• Participant has severe GL at maximum frown as assessed by both the investigator and participant using the Facial Wrinkle Scale - Glabellar Lines (FWS-GL) at Baseline.

Exclusion Criteria:

• History of known immunization to any botulinum toxin serotype.

• History of known hypersensitivity to any botulinum toxin serotype, or any other constituents of the study drug or its excipients, and/or other products in the same class.

• Presence or history of any medical condition that may place the participant at increased risk following exposure to OnabotA X 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 site of study drug injection

• 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 baseline or Day 1 as determined by the investigator
