Details and patient eligibility

About

The clinical trial aims to test the long term safety of a new drug for acne vulgaris. The trial is performed to answer this question "Is it safe to apply the IMP daily for up to 52 weeks?". The trial aims to accurately measure the safety and the effects of the new treatment (N-Acetyl-GED-0507-34-LEVO gel 5%) and to achieve this, patients will be review the drug containing the active ingredient.

Participants will:

Take drug every day for up to 52 weeks
Visit the site once every 4 weeks for checkups and tests (where applicable) for the first 3 months of treatment, then visit the site every 13 weeks approximately for checkups and tests (where applicable).
Record on a diary the daily/weekly applications of the study drug at home, and record any adverse events

Inclusion criteria

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. Patients who turn 50 during the pivotal study can roll over to the LT study.
Diagnosis at screening and baseline visits:
a. Patients affected by facial acne vulgaris with an Investigator's Global Assessment (IGA) score: =1 or 2 for pivotal-naïve* patients not included in pivotal 12 Week treatment studies ≥ 0 for patients completing the 12-Week treatment period according to protocol in the pivotal Phase 3 trials (NAC-GED-0507-ACN-01-23-A and NAC-GED-0507-ACN-01-23-B)
b. Patients affected by truncal acne (optional criteria) on areas of the trunk (shoulders, upper back and upper anterior chest) accessible for patient's self- application of study medication with a Physician Global Assessment (PGA) severity grade: =1 or 2 for pivotal-naïve* patients not included in the pivotal 12Week treatment studies ≥ 0 and < 4 for patients completing the 12-Week treatment period according to protocol in the pivotal Phase 3 trials (NAC-GED-0507-ACN-01-23-A and NAC-GED-0507-ACN-01-23-B)
- Pivotal-naïve: Patients not rolling over from NAC-GED-0507-ACN-01-23-A and NAC-GED-0507-ACN-01-23-B. If the pivotal-naïve patient is ≥ 9 and ≤ 14 years old and declined participation to pivotal Phase 3 study, a 12-week period should run before inclusion in the present study. During the 12-week period the patients will be allowed to follow their doctor's instructions regarding treatment of acne.
Full comprehension Patients and their parents/legal guardian(s) (for < 18 years old patients) can comprehend the whole nature and purpose of the study, including possible risks and side effects, and are able to cooperate with the Investigator and to comply with the requirements of the entire study.
Contraception and fertility: Women of childbearing potential must be using an effective contraception method during the entire duration of the study. Effective contraception methods are those considered at least "acceptable" according to CTFG Recommendations. A prior stable treatment period is required for the following reliable methods of contraception:
1. Hormonal oral, implantable, transdermal, or injectable contraceptives must be stable for at least 6 months before the screening visit
2. A non-hormonal intrauterine device (IUD) must be started at least 2 months before the screening visit.

- Patients with acne requiring systemic treatment.
Beard and facial/body hair, tattoos:
- Patients with a beard or who intend to grow a beard and/or to perform a facial tattoo during the study
- Patients with facial hair or facial tattoos that could interfere with study assessments in the investigator's opinion
- For patients with truncal acne: body hair, tattoos (or who intend to perform them) on the shoulders, upper back or upper anterior chest accessible to self-application of study medication by the patient (evaluable area) that may interfere with the study assessments in the investigator's opinion.
Skin diseases: Patients with other active skin diseases (e.g., urticaria, atopic dermatitis, sunburn, seborrheic dermatitis, perioral dermatitis, rosacea, skin malignancies) or active skin infections in the facial or truncal region (bacterial, fungal, or viral) or any other facial or truncal disease or condition that might interfere with the evaluation of acne or place the patient at unacceptable risk.

Topical therapies: Patients who are currently using, plan to use during the study, or discontinued less than 4 weeks before study baseline the use of prescribed or over-the-counter topical therapies for the treatment of acne, including but not limited to: corticosteroids, antibiotics, azelaic acid, benzoyl peroxide, salicylates, α-hydroxy/glycolic acid, any other topical cosmetic therapy for acne and retinoids on the face/trunk.
