A Study to Assess the Safety and Efficacy of Co-Reconstituted TrenibotulinumtoxinE and OnabotulinumtoxinA in Adult Participants With Moderate to Severe Upper Facial Lines
What this study is about
The objective of this Phase 2 study is to assess the safety and effectiveness of single treatment of trenibotulinumtoxinE and onabotulibumtoxinA combination in adult participants with moderate to severe upper facial lines. The study has two parts; Part 1 evaluates treatment for glabellar lines.

Primary outcome measures
Number of Participants with Adverse Events (AEs)
Time frame: Up to Day 150
An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.
Percentage of Participants Achieving None or Mild on the Investigator-Assessed Allergan Glabellar Lines Severity Scale (AGLSS)
Time frame: Day 7
Achievement of None or Mild on the investigator-assessed AGLSS. The AGLSS is a validated 4-point scale (0=None through 3=Severe) used to assess glabellar line severity. A response of None or Mild indicates improvement in glabellar line severity.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- For glabellar lines (GL) indication: participant must have moderate or severe GL at maximum furrow as assessed by both the investigator and participant using the AGLSS at Screening and Baseline (Day 1) visits.
- Participant must be in good health as per investigator's judgment based on medical history, physical examination, vital sign measurements, 12-lead electrocardiogram (ECG) parameters, clinical laboratory evaluations, and neurological assessment.
- In the investigator's opinion, participant must not have a condition or be in a situation that may put the participant at significant risk, may confound the study results, or may interfere significantly with the participant's participation in the study.
Exclusion criteria
- For GL Indication: Severe GL at rest as assessed by the investigator using the AGLSS at Screening or Baseline (Day 1).
- History of immunization to any botulinum neurotoxin serotype or hypersensitivity to any botulinum neurotoxin serotype or any other constituents of the study drug or its excipients
- Active infection or dermatological condition at the treatment injection sites.
- Medical condition that may put the subject at increased medical risk with exposure to botulinum toxin, including diagnosed myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other condition that might interfere with neuromuscular function

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
