Comparing trifarotene 50 mcg/g cream with vehicle cream for moderate facial and trunk acne in Chinese patients

A Multicenter, Randomized, Double-blinded, Parallel-group, Vehicle-controlled Study to Compare the Efficacy, Safety and Pharmacokinetics of Trifarotene 50 mcg/g Cream in Chinese Subjects With Acne Vulgaris

This tests whether applying trifarotene 50 mcg/g cream once daily for 12 weeks helps Chinese people aged 9 and older who have moderate acne on the face and trunk.

What this trial studies

Participants who meet lesion-count and severity criteria will apply either trifarotene 50 mcg/g cream or a matching vehicle cream once daily for 12 weeks. The study compares acne outcomes on both the face and reachable trunk areas and collects safety and pharmacokinetic data. Eligible participants must have moderate facial acne (IGA grade 3) with specified minimum inflammatory and non-inflammatory lesion counts, and similar criteria apply for the trunk where applicable. Measurements will include lesion counts and standard severity scores at screening, baseline, and follow-up visits.

Who should consider this trial

Good fit: Chinese males or females aged 9 years or older with moderate facial (IGA grade 3) and reachable truncal (PGA grade 3) acne and the specified minimum lesion counts are ideal candidates.

Not a fit: People with mild or severe acne, non-Chinese individuals, those who cannot self-apply to the trunk, or those who do not meet the required lesion counts are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the cream could reduce inflammatory and non-inflammatory acne lesions on the face and trunk and provide an approved topical option tailored to Chinese patients.

How similar studies have performed: Other clinical trials of trifarotene have shown effectiveness for treating facial and truncal acne, and this study aims to confirm efficacy, safety, and pharmacokinetics in a Chinese population.

Eligibility criteria

Inclusion Criteria:

Participants must meet the following criteria to be included in the study:

1. Male or female Chinese participants aged 9 years or older at the screening visit.
2. A minimum of 20 inflammatory lesions and 25 non-inflammatory lesions on the face at Screening and Baseline.
3. Facial acne vulgaris severity grade 3 (moderate) on the IGA scale at Screening and Baseline.
4. A minimum of 20 inflammatory lesions and 20 non-inflammatory lesions but no more than 100 non-inflammatory lesion counts on the trunk (shoulders, upper back, and upper anterior chest) reachable for self-application of investigational product by the participant at Screening and Baseline (optional criterion for participant between 9 and 11 years of age).
5. Acne vulgaris severity grade 3 (moderate) on the PGA scale at Screening and Baseline visits on trunk (shoulders, upper back and upper anterior chest) reachable for self-application of investigational product by the participant (optional criterion for participants between 9 and 11 years of age).
6. Female participants of non-childbearing potential, i.e., premenstrual, or postmenopausal. Postmenopausal participants must meet one criterion at Screening:

   * Absence of menstrual bleeding for 1 year before screening with no other medical reason, confirmed with follicle-stimulating hormone level in the postmenopausal range.
   * Documented hysterectomy, bilateral salpingectomy, or bilateral oophorectomy at least 3 months before Screening.
7. Female participants of childbearing potential (i.e., fertile, after menarche and until becoming postmenopausal unless permanently sterile) must have a negative serum pregnancy test at the screening visit and a negative urine pregnancy test (UPT) at the baseline visit (with a sensitivity of 25 international units per litre \[IU/L\] or less). They must use at least 1 adequate and approved method of contraception throughout the study and for 1 month after the last dose of investigational product.
8. Premenstrual participants who start menses during the study must use at least 1 adequate and approved method of contraception throughout the study and for 1 month after the last dose of investigational product.
9. Willing and able to comply with all the time commitments and procedural requirements of the clinical study protocol.
10. Understands and signs an informed consent form (ICF) at the screening visit, before any investigational procedures are performed.
11. Participants who are younger than 18 years of age and whose parent/legal representative is willing/able to comply with the study requirements and understand/sign the ICF at the screening visit, before any investigational procedures are performed, will sign the assent ICF at the screening visit.
12. At selected clinical sites: If a participant who is 18 years of age or older at the screening visit and agrees to participate in study photographs, verified by dating and signing a separate approved photography ICF. For participants younger than 18 years of age, an assent photography ICF signed by the participant in conjunction with a photography ICF signed by the parents(s)/legal representative at the screening visit.
13. Participant is informed of terms pertaining to personal information protection and privacy and is willing to share personal information and data, in accordance with local regulations.

Exclusion Criteria:

Participants meeting the following criteria at the screening or baseline visits are ineligible to participate in this study:

2. Severe forms of acne (e.g., acne conglobata, acne fulminans) or secondary acne form (e.g., chloracne, drug-induced acne) at the screening and baseline visits.
3. More than 1 nodule on the face at the screening and baseline visits.
4. More than 1 nodule on the trunk at the screening and baseline visits.
5. Any acne cyst on the face at the screening and baseline visits.
6. Any acne cyst on the trunk at the screening and baseline visits.
7. Facial or truncal hair that may interfere with the study assessments according to investigator's judgment.

10. Abnormal laboratory test results at the screening visit (hematology, comprehensive metabolic panel, and urinalysis) judged as clinically significant by the investigator (to be checked before the baseline visit), which may interfere with the interpretation of the study results and/or put the participant at significant risk (e.g., elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) (\> 3 × upper limit of normal \[ULN\])).
