About this study

Official title: A Double-Blinded, Randomized, Controlled Study to Compare the Efficacy, Time to Onset, and Duration of Effect of Botulinum Type A Toxins in the Treatment of Glabellar Frown Lines

The purpose of the study is to provide preliminary comparative data on BoNT/A-DP versus Botox Cosmetic. Subsequently the sample size is primarily based on clinical judgement and practical considerations.

Read the detailed description

This will be a multi-center, randomized, double-blind, comparator-controlled study. The study will take place in the EU, US and Canada.

To allow all subjects to profit from treatment and to obtain adequate data for BoNT/A DP treatment, the study will be comprised of a double-blinded treatment comparing BoNT/A-DP with Botox Cosmetic (ratio 1:1). Primary and secondary endpoints will compare efficacy, safety and subject satisfaction after a single treatment of the investigational BoNT/A DP to an existing commercially available product (Botox Cosmetic).

Two hundred subjects will be enrolled, which should allow for a precise estimate of response rate and for post-hoc sensitivity analyses.

The duration of study participation for each subject will be up to 18 weeks, to include screening (maximum of 2 weeks; re-screening will not be permitted), and a single treatment (comprised of one injection at five injection points) of BoNT/A-DP (Group A) or Botox Cosmetic (Group B) followed by six efficacy and safety follow-up visits. A total of 200 subjects will be randomized 1:1 to Group A or Group B at Baseline. Both investigators and subjects will be blinded to treatment. Investigators and subjects will evaluate the severity of glabellar lines independently.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Facial Wrinkle Scale (FWS) Score of 0 or 1 and an Improvement of ≥ 1 Points in FWS Score (at Maximum Frown) at Week 4 Visit Relative to Baseline, Based on Both the Investigators´ and the Subjects´ In-clinic Assessments.

    The primary endpoint is the percentage of subjects among BoNT/A-DP and Botox Cosmetic groups with a Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement of ≥ 1 points in FWS score (at maximum frown) at week 4 visit (of the first treatment cycle) relative to baseline (responders), based on both the investigators' and the subjects' in-clinic assessments. Thus, the primary endpoint is a composite endpoint comprising investigator and subject assessments of treatment effectiveness. FWS scores are a four-point rating scale as follows: 0 = no facial wrinkles; 1 = mild facial wrinkles; 2 = moderate facial wrinkles; and 3 = severe facial wrinkles. Subjects with missing in-clinic assessments with the FWS at Baseline or Week 4 were assigned as non-responders.

    Measured: week 4

Secondary outcomes (9)
  1. Responder Status (With a Facial Wrinkle Scale (FWS) Score of 0 or 1 and at Least 1 Point Reduction at Maximum Frown) Based on Independent Investigator Assessment and Subject Assessment at Weeks 1, 2, 8, 12 and 16

    The percentage of responders based on the independent investigator assessment and subject assessment at Weeks 1, 2, 8, 12 and 16 after a single treatment with BoNT/A-DP and compared to a single treatment of Botox Cosmetic. Responder is defined as having a Facial Wrinkle Scale (FWS) score of 0 or 1 and at least 1 point reduction in FWS score at maximum frown over Baseline, on the 4-point FWS. FWS scores are ranked as 0 (no facial wrinkles), 1 (mild facial wrinkles), 2 (moderate facial wrinkles) and 3 (severe facial wrinkles). Subjects with missing in-clinic assessments with the FWS at Baseline or the respective visit were assigned as non-responders.

    Measured: Weeks 1, 2, 8, 12 and 16

  2. Responder Status (With a Facial Wrinkle Scale (FWS) Score of 0 or 1 and at Least 2 Point Reduction at Maximum Frown) Based on Independent Investigator Assessment and Subject Assessment at Weeks 1, 2, 4, 8, 12 and 16

    The percentage of responders based on the independent investigator assessment and subject assessment at Weeks 1, 2, 4, 8, 12 and 16 after a single treatment with BoNT/A-DP and compared to a single treatment of Botox Cosmetic. Responder is defined as having a Facial Wrinkle Scale (FWS) score of 0 or 1 and at least 2 point reduction in FWS score at maximum frown over Baseline, on the 4-point FWS. FWS scores are ranked as 0 (no facial wrinkles), 1 (mild facial wrinkles), 2 (moderate facial wrinkles) and 3 (severe facial wrinkles). Subjects with missing in-clinic assessments with the FWS at Baseline or the respective visit were assigned as non-responders.

    Measured: Weeks 1, 2, 4, 8, 12 and 16

  3. Responder Status (With a Facial Wrinkle Scale (FWS) Score of 0 or 1 and at Least 1 Point Reduction at Rest) Based on Independent Investigator Assessment and Subject Assessment at Weeks 1, 2, 4, 8, 12 and 16

    The percentage of responders based on the independent investigator assessment and subject assessment at Weeks 1, 2, 4, 8, 12 and 16 after a single treatment with BoNT/A-DP and compared to a single treatment of Botox Cosmetic. Responder is defined as having a Facial Wrinkle Scale (FWS) score of 0 or 1 and at least 1 point reduction in FWS score at rest over Baseline, on the 4-point FWS. FWS scores are ranked as 0 (no facial wrinkles), 1 (mild facial wrinkles), 2 (moderate facial wrinkles) and 3 (severe facial wrinkles). Subjects with missing in-clinic assessments with the FWS at Baseline or the respective visit were assigned as non-responders.

    Measured: Weeks 1, 2, 4, 8, 12 and 16

  4. Time to Onset of Effect Based on Independent Investigator Assessment and Subject Assessment

    Time to onset of effect in days, as measured at Weeks 1, 2, and 4, based on independent investigator and subject assessments after a single treatment with BoNT/A-DP and compared to Botox Cosmetic. Onset of effect is defined as at least 1 point improvement in Glabellar Line Scale - Investigator (GLS-I) and Glabellar Line Scale - Subject (GLS-S) score relative to Baseline at maximum frown in glabellar lines. GLS-I and GLS-S both use the same 4-point scale, ranked as 0 (No lines/minimal lines), 1 (Mild lines), 2 (Moderate lines) and 3 (Severe lines).

    Measured: From treatment at Day 0 to Week 4

  5. Duration of Effect Based on Independent Investigator Assessment and Subject Assessment

    For subjects who are responders at week 4, duration of effect in days is assessed based on independent investigator and subject assessments after a single treatment with BoNT/A-DP and compared to Botox Cosmetic. Responder is defined as having a Facial Wrinkle Scale (FWS) score of 0 or 1 and at least 1 point reduction in FWS score at maximum frown over Baseline, on the 4-point FWS. FWS scores are ranked as 0 (no facial wrinkles), 1 (mild facial wrinkles), 2 (moderate facial wrinkles) and 3 (severe facial wrinkles). Effect is deemed to be lost when scores return to Baseline or worse values. Duration of effect is defined as (the date that loss of response occurred) - (date of single study treatment ) + 1.

    Measured: 16 Weeks

  6. FACE-Q Satisfaction With Outcome Scale Based on Subject Assessment at Weeks 4, 12 and 16 Satisfaction With Outcome Scale.

    Summary of FACE-Q satisfaction with outcome scale based on subject assessment at weeks 4, 12 and 16 after a single treatment and compared to Botox Cosmetic. The FACE-Q Satisfaction with Outcome scale is a patient-reported outcome measure designed to assess a patient's satisfaction with the results of a facial aesthetic procedure. This scale comprises six items, each with four response options: "definitely agree," "somewhat agree," "somewhat disagree," and "definitely disagree."

    Measured: Weeks 4, 12 and 16

  7. Number of Participants With Treatment-emergent Adverse Events (TEAEs), Serious AEs (SAEs) and AEs of Special Interest (AESIs)

    Frequency, seriousness and severity of treatment-emergent adverse events (TEAEs), serious AEs (SAEs) and AEs of special interest (AESIs), as well as causal relationship to the study medication and the study procedure, during the entire study period. A subject with multiple occurrences of an adverse event is counted only once within the worst severity category.

    Measured: through study completion, an average of 16 weeks

  8. Change From Baseline in Blood Pressure at Weeks 1, 4, 12 and 16

    Summary of change from baseline in diastolic/systolic blood pressure at weeks 1, 4, 12 and 16 after a single treatment and compared to Botox Cosmetic.

    Measured: Weeks 1, 4, 12, and 16
