• 2 other identifiers: NAC-GED-0507-ACN-01-23-B2023-510341-19-00
• Study Type: interventional

Brief Summary

The clinical trial aims to test a new drug for acne vulgaris. The trial is performed to answer this question "Is it possible to reduce the number of skin lesions on your face/trunk, after daily applications for 12 consecutive weeks of a new drug?". The trial aims to accurately measure the effects of the new treatment (N-Acetyl-GED-0507-34-LEVO gel 5%) and to achieve this, patients will be randomly assigned to one of the following treatments:

• Study drug 1: test item, containing active ingredient
• Study drug 2: a preparation not containing any active ingredient (vehicle). Researchers will compare active to vehicle to see if there are differences in the efficacy. Participants will:
• Apply drug or a placebo every day for 12 weeks
• Visit the site once every 4 weeks for checkups and tests (where applicable)
• Record on a diary the daily applications of the study drug at home, and record any adverse events

Outcome Measures

Primary Outcomes (2)

• The relative change from baseline in total lesion count (inflammatory plus non-inflammatory) at V5/Wk12 on the face

  From enrollment to the end of treatment at 12 weeks

• Proportion of patients with an IGA success (face) at V5/Wk12.

  The Investigator Global Assessment (IGA) for acne is a 5-point clinical scale (0-4) used by dermatologists to assess overall acne severity based on lesion type and extent. It ranges from 0 (clear) to 4 (severe), providing a rapid, qualitative snapshot of facial acne, commonly used to measure treatment efficacy.

  From enrollment to the end of treatment at 12 weeks

Secondary Outcomes (10)

• Absolute change from baseline in total lesion count at V5/Wk12 (face)

  From enrollment to the end of treatment at 12 weeks

• Percentage of patients who achieve an IGA success over the study duration (face)

  From enrollment to the end of treatment at 12 weeks

• Change from baseline in total lesion count over the study duration (face)

  From enrollment to the end of treatment at 12 weeks

• Change from baseline in inflammatory lesion count over the study duration (face)

  From enrollment to the end of treatment at 12 weeks

• Change from baseline in non-inflammatory lesion count over the study duration. (face)

  From enrollment to the end of treatment at 12 weeks

Other Outcomes (4)

• Dermatology Life Quality Index (DLQI)

  From enrollment to the end of treatment at 12 weeks

• Children's Dermatology Life Quality Index ( C-DLQI for patients from 9 to 16 years old),

  From enrollement to the end of treatment at 12 weeks

• SCAR-S Scar Assessment at the Baseline and Week 12/EoT visits

  From enrollment to the end of treatment at 12 weeks

You may qualify if:

• Informed consent obtained: Written informed consent, before any study-related procedure, personally signed and dated by the patient if the patient is ≥ 18 years old, or signed and dated by the parents or the legal guardian(s) if the patient is ≥ 9 to \< 18 years old. An additional informed assent form must be signed by patient if ≥ 9 to \<18 years old to confirm his willingness to participate in the study. If the patient becomes 18 years of age during the study, the patient must provide written informed consent at that time to continue study participation
• Sex and age: Male and female patients aged ≥ 9 and \<50 years
• Diagnosis at screening and baseline visits:
• a) Patients affected by facial acne vulgaris with: Investigator's Global Assessment (IGA) score:
• equal to 3-4 if patient is \> 14 and \< 50 years old
• ≥ 2 if the patient is ≥ 9 and ≤ 14 years old. Face Inflammatory lesions: ≥ 20 and ≤ 100 inflammatory lesions (papules and pustules) and ≤ 1 nodules on the face. Face Non-inflammatory lesions: ≥ 20 and ≤ 100 non-inflammatory lesions (open and closed comedones) on the face
• b) Patients affected also by truncal acne (optional criteria): The patient has a truncal acne on areas of the trunk (shoulders, upper back and upper anterior chest) accessible for patient's self-application of study medication with a severity grade equal to 2 or 3 on the Physician Global Assessment (PGA) scale. The patient has a minimum of 20 inflammatory lesions (papules and pustules) and 20 non-inflammatory lesions (open and closed comedones) but no more than 100 non-inflammatory lesions and no more than 100 inflammatory lesions and ≤ 1 nodules on areas of the trunk (shoulders, upper back and upper anterior chest) reachable to patient's self-application of study medication at screening and baseline.
