About This Trial

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 45 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

The face, scalp, axillae, and intertriginous areas are to be excluded in this assessment, if psoriasis is present. - Has an area of plaque psoriasis appropriate for topical treatment that involves a BSA of at least 10% at Screening and Baseline. The face, scalp, axillae, and intertriginous areas are to be excluded in this calculation. - Is willing and able to avoid prolonged exposure of the treatment area to ultraviolet radiation (natural and artificial) for the duration of the study. - Is in good general adrenal health, as determined by a 30-minute postcosyntropin stimulation serum cortisol level that is \>18 μg/dL at the Screening visit. - Females of childbearing potential and females who are pre-menses (9 years and older) must be willing to practice effective contraception for the duration of the study. Who Should NOT Join This Trial: - Has a history of adrenal disease. - Presents with any concurrent skin condition that could interfere with the evaluation of the treatment areas, as determined by the Investigator. - Is pregnant, nursing an infant, or planning a pregnancy during the study period. - Has received treatment with any investigational drug or device within 60 days or 5 drug half-lives (whichever is longer) prior to baseline or is concurrently participating in another clinical study with an investigational drug or device. - Received treatment with a topical antipsoriatic drug product other than corticosteroids within 14 days prior to the Baseline visit and/or treatment containing corticosteroids within 28 days prior to the screening HPA axis stimulation test. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Frequently Asked Questions

What is the NCT03987763 clinical trial studying?

This study is to evaluate the safety, the systemic exposure of halobetasol propionate (HP), and the hypothalamic-pituitary-adrenal (HPA) axis suppression potential for topically applied IDP-122 lotion in pediatric participants with moderate to severe plaque psoriasis. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT03987763?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT03987763?

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
