About this study

Official title: A 12-Week, Phase 4, Open-Label Study To Assess Safety, Pharmacokinetics, and Treatment Effect of CABTREO (Clindamycin Phosphate 1.2%, Adapalene 0.15%, and Benzoyl Peroxide 3.1%) Topical Gel In Pediatric Participants Ages 9 to 11 Years, 11 Month With Acne Vulgaris

This study is to evaluate the safety, pharmacokinetics, and treatment effect for topically applied CABTREO lotion in pediatric participants ages 9 to 11 years, 11 months with Acne Vulgaris.

Read the detailed description

This is an open-label study designed to assess the safety, plasma PK, and treatment effect of topically applied CABTREO. This study includes both a main study and a PK sub-study. All participants will undergo a screening period of up to 5 weeks (up to 35 days) and a treatment period of up to 12 weeks (approximately 84 days). A subset of participants in the main study will be included in the PK sub-study. To be eligible for this study, participants must be between 9 years and 11 years, 11 months of age, inclusive, and have a clinical diagnosis of moderate to severe acne, defined as a score of 3 (moderate) or 4 (severe) on the Evaluator's Global Severity Score (EGSS). Participants must also have at least 30 facial acne inflammatory lesions, at least 35 facial acne noninflammatory lesions, and no more than 2 facial nodules; participants should also have acne lesions on at least 1 region of the trunk (chest, back, and/or shoulder).

Conditions

  • CABTREO is a fixed-combination product of clindamycin phosphate 1.2%/BPO 3.1%/adapalene 0.15%.Drug

    Also called IDP-126

    The study drug will be applied topically to the treatment areas at home, each the morning, for a period of 12 weeks, with the exception of study visit days (baseline [Day 1], and Days 14, 15 [PK substudy only], 28, 29 [PK substudy only], 56, and 84) where study drug will be applied by the participants after the study visit is completed at the study center. The study drug will be applied as a thin coating that is gently rubbed into the skin.

What is being measured

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

  1. Incidence of Treatment-Emergent Adverse Events

    Starting after signing the informed consent/assent document, and continuing through the end of the study, participants will be assessed for the occurrence of new AEs and changes in ongoing AEs. The descriptions of all AEs will include the dates of onset and resolution (if resolved), maximum severity, seriousness, action taken regarding the study drug, corrective treatment, outcome, and the investigator's assessment of causality. Worsening of disease will not be considered an AE unless it results in discontinuation of the participant from the study or requires medical intervention prohibited by the protocol. All AEs will be followed to resolution or until stable, as determined by the investigator.

    Measured: All AEs will be followed from onset of the adverse event through the end of Study Week 12 visit

  2. Change in Inflammatory Lesions

    Changes from Baseline to each study visit in inflammatory lesion counts

    Measured: Baseline through Week 12

  3. Change in Non-inflammatory Lesions

    Changes from Baseline to each study visit in non-inflammatory lesion counts

    Measured: Baseline through Week 12

  4. EGSS Results

    Collection of EGSS results from Baseline visit through end of study Week 12

    Measured: Baseline through Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing CABTREO is a fixed-combination product of clindamycin phosphate 1.2%/BPO 3.1%/adapalene 0.15%. in people with Acne Vulgaris, run by Bausch Health Americas, Inc. at 15 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Emily N Hughes, MACPR (731-415-3174, Emily.Hughes@BauschHealth.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Adverse Events (time frame: All AEs will be followed from onset of the adverse event through the end of Study Week 12 visit). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2026.
