Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Presence of four (medial and lateral, left and right) prominent platysmal bands
  • Moderate to severe platysmal bands as assessed by the investigator and subject on the MAPS-D at maximum contraction

Exclusion Criteria:

  • Any serious disease or disorder (medical or psychiatric) that could interfere with the safe completion of treatment or compromise subject safety
  • Botulinum toxin treatment in the face (below the lower orbital rim), neck, or chest within the last 12 months prior to study treatment
  • History of lower face surgery, neck or chest surgery, aesthetic procedures (e.g., ablative skin resurfacing, laser, chemical peel, micro-focused ultrasound, deoxycholic acid injections, micro-needling, non-surgical fat reduction procedure), and orthodontic procedures (e.g., braces) in the 12 months prior to study treatment
  • Previous use of any permanent (non-biodegradable) or semi-permanent (e.g., calcium hydroxylapatite, poly-L-lactic acid, polymethyl methacrylate, etc.) facial tissue augmentation therapy, lifting sutures, permanent implants or autologous fat to the lower face (i.e., below the level of the bottom of the nose), neck, or chest within 24 months prior to study treatment
  • Previous use of any hyaluronic acid based or collagen based biodegradable facial tissue augmentation therapy to the lower face (i.e., below the level of the bottom of the nose), neck, or chest within 12 months prior to study treatment
  • Any medical condition that may put the subject at increased risk with exposure to botulinum toxin of any serotype, including myasthenia gravis, Lambert-Eaton-Syndrome, amyotrophic lateral sclerosis, or any other disorder that might interfere with neuromuscular function
  • Female of childbearing potential not using a highly effective method of birth control, planning to get pregnant, or pregnant or lactating

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline on the MAPS-D Score at Maximum Contraction as Assessed by the Investigator at Visit 4 (V4)
Time Frame: Baseline (Screening Visit), Week 2 (V4)
The platysma area will be assessed live by the investigator at maximum contraction and graded according to the validated five-point Merz Aesthetic Platysma Scale-Dynamic (MAPS-D). Scores range from Grade 1 (none to minimal) to Grade 5 (very severe).
Baseline (Screening Visit), Week 2 (V4)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Related Treatment Emergent Adverse Events (Related TEAEs)
Time Frame: Baseline up to Week 17/End of Study
TEAEs are defined as adverse events (AEs) with onset or worsening on or after date and time of first dose of study treatment. An AE is considered to be related if a causal relationship between NT 201 and the AE is at least reasonably possible.
Baseline up to Week 17/End of Study
Change From Baseline on the MAPS-D Score at Maximum Contraction as Assessed by the Subject at V4
Time Frame: Baseline (Screening Visit), Week 2 (V4)
The platysma area will be assessed by the subjects at maximum contraction and graded according to the validated five-point MAPS-D. Scores range from Grade 1 (none to minimal) to Grade 5 (very severe).
Baseline (Screening Visit), Week 2 (V4)
