Treatment and study plan

TEOSYAL® RHA Ultra Deep

Device

A sterile, biodegradable, biocompatible, viscoelastic, clear, colorless, homogenized gel implant. It consists of cross-linked hyaluronic acid produced by fermentation of Streptococcus equi bacteria, formulated to a concentration of 23 mg/mL and 0.3% w/w lidocaine in a physiologic buffer. It is supplied in individual treatment syringes with 27Gauge ½" disposable sterile needles.

Primary outcomes

  1. Non-inferiority of the Delta of the WSRS Score Between W24 and Baseline for TEOSYAL® RHA Ultra Deep Versus Perlane-L® for the Correction of Moderate to Severe Naso-Labial Folds Based on the Wrinkle Severity Rating Scale (WSRS) Score Assessed by the BLE.

    Time frame: Baseline and 24 weeks after last treatment

    WSRS (Wrinkle Severity Rating Scale) is a validated 5-point scale with 1 being 'absent' and 5 being 'extreme'.

    BLE =Blinded Live Evaluator

Secondary outcomes

  1. Post Injection Treatment Responses (From Common Treatment Responses (CTR) Diary) for Safety Evaluation of TEOSYAL® RHA Ultra Deep Versus Perlane-L®

    Time frame: During 14 days after initial treatment (D0) and touch-up (2 weeks)

    The subjects received a diary booklet and instructions for recording his/her observations of the Common Treatment Responses of the study treatments for the first 14 days after each treatment (initial, touch-up). The diary was discussed during each telephone follow-up visit. Subjects should complete the diary at approximately the same time each day (i.e., am or pm).

    The subject diary captured the following Common Treatment Responses (CTR) that occur following the injection of a dermal filler; specifically, redness, pain, tenderness, firmness, swelling, lumps/bumps, bruising, itching, discoloration, and "other".

    The 14-day patient CTR diary included a detailed glossary describing all signs/symptoms listed in the diary; an option was provided to rate "other" if the subject experienced a sign/symptom that is not listed.

    The table presents the number of subjects experiencing at least 1 Common Treatment Response (CTR)

  2. Assessment of Injection Site Pain (Visual Analog Scale) of TEOSYAL® RHA Ultra Deep Versus Perlane-L®

    Time frame: During Injection and 5, 15, 30 minutes post-injection

    VAS is a 100 mm Visual Analog Scale with 0 meaning no pain and 100 meaning intolerable pain

  3. Delta of the WSRS Score Between W24,36,52 and 64 and Baseline for TEOSYAL® RHA Ultra Deep Versus Perlane-L® for the Correction of Moderate to Severe NLFs Based on the Wrinkle Severity Rating Scale (WSRS) Score Assessed by the Blinded Live Evaluator (BLE)

    Time frame: Baseline and Weeks 24, 36, 52, 64

    WSRS (Wrinkle Severity Rating Scale) is a validated 5-point scale with 1 being 'absent' and 5 being 'extreme'.

  4. Delta of the WSRS Score Between W2,4,12,24,36,52,64 and Baseline for TEOSYAL® RHA Ultra Deep Versus Perlane-L® for the Correction of Moderate to Severe NLFs Based on the Wrinkle Severity Rating Scale (WSRS) Score Assessed by the Treating Investigator (TI)

    Time frame: Baseline and Weeks 2, 4, 12, 24, 36, 52, 64

    WSRS (Wrinkle Severity Rating Scale) is a validated 5-point scale with 1 being 'absent' and 5 being 'extreme'.

  5. Percentage of Responders Based on the Intra-individual Improvement of at Least One Grade in the Wrinkle Severity Rating Scale (WSRS) Compared to Baseline Assessed by the BLE

    Time frame: Baseline and Weeks 24, 36, 52, 64

    A responder correspond to a subject with an intra-individual improvement of at least one grade in the WSRS compared to Baseline

  6. Percentage of Responders Based on the Intra-individual Improvement of at Least One Grade in the Wrinkle Severity Rating Scale (WSRS) Compared to Baseline Assessed by the TI

    Time frame: Baseline and Weeks 2, 4, 12, 24, 36, 52, 64

    A responder correspond to a subject with an intra-individual improvement of at least one grade in the WSRS compared to baseline

  7. Number of Subjects Scored Either "Much Improved" or "Improved" on Global Aesthetic Improvement (GAI) by the Blinded Live Evaluator (BLE)

    Time frame: Weeks 24, 36, 52, 64

    Global Aesthetic Improvement (GAI) is a subjective 5-grade scale comprised of "much improved, improved, no change, worse, and much worse".

    GAI was assessed using the baseline photograph. Each side of the face was assessed independently.

  8. Number of Global Aesthetic Improvement (GAI) Responders (i.e., Scoring Either "Much Improved" or "Improved") on GAI Scale.

    Time frame: Weeks 4, 12, 24, 36, 52, 64

    Global Aesthetic Improvement (GAI) is a subjective 5-grade scale comprised of "much improved, improved, no change, worse, and much worse".

    GAI was assessed using the baseline photograph. Subjects will be instructed: "Use a mirror to compare your face to the photograph provided to you and rate the degree of aesthetic improvement by using the following scale".

    Each side of the face was assessed independently.

  9. Subject's Perception of Treatment Effectiveness as Per the FACE-Q (NLF Domain) Questionnaire

    Time frame: Immediately post-injection, and weeks 2, 4, 12, 24, 36, 52, 64

    The FACE-Q measures the experience and outcomes of aesthetic facial procedures from the patient's perspective.

    FACE-Q questionnaire is composed of 5 questions with a score linked to answers (1 being 'Not at all' and 4 being 'Extremely').

    The subject was instructed as follows: "These questions ask about how you look right now. With your nasolabial folds in mind (the deep lines that run downward from the sides of your nose), in the past week, how much have you been bothered by:", and provided response.

    • How deep your nasolabial fold are?
    • How your nasolabial folds look when your face is relaxed (still)?
    • How old your nasolabial folds make you look?
    • How your nasolabial folds look when you smile?
    • How your nasolabial folds look compared with other people your age? To calculate the FACE-Q, outcomes from all 5 questions were pooled and adapted to a scale to 100 units. Data were also transformed so that higher scores reflected a beneficial outcome.

  10. Subject's Satisfaction Score

    Time frame: Weeks 2, 4, 12, 24, 36, 52, 64

    Subjective 5-point scale with 1 being 'very satisfied' and 5 being 'very dissatisfied'

  11. Volume to Obtain Optimal Cosmetic Result (Initial Treatment + Touch-up)

    Time frame: Week 2

  12. Number of Subjects Receiving Touch-up Treatment

    Time frame: Week 2

  13. Number of Subjects Receiving Re-treatment

    Time frame: Weeks 24, 36, 52, 64
