Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

ARQ-154-127 is a Phase 1, open-label, single arm, maximum usage pharmacokinetic and safety study of roflumilast foam 0.3% in participants with scalp and body psoriasis.

The goal of the study is to:

  • Evaluate the systemic exposure and characterize the plasma pharmacokinetic (PK) profile of ARQ-154 foam 0.3%.
  • Assess the safety and tolerability of ARQ-154 foam 0.3%

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Males and females, ages 2 years to < 12 years old at Day 1.
  • Clinical diagnosis of psoriasis vulgaris of at least 2 months duration at Screening as determined by the Investigator.
  • Scalp psoriasis with an Investigator Global Assessment (S-IGA) of scalp disease severity of at least Moderate ('3') at Day 1.
  • An IGA of body (non-scalp) psoriasis (B-IGA) of at least Mild ('2') at Day 1.
  • Extent of scalp psoriasis involving ≥ 10% of the total scalp at Day 1.
  • Body psoriasis (non-scalp) involving at least 3% BSA on Day 1.

Exclusion Criteria:

  • Participants who cannot discontinue medications and treatments prior to Day 1 (first application of IP).
  • Current diagnosis of non-plaque forms of psoriasis. Current diagnosis of drug-induced psoriasis.
  • Participants who have significant active systemic or localized infection or have had any infection that required oral or intravenous administration of antibiotics, antifungal or antiviral agents within 7 days prior to Day 1.
  • Participants with skin conditions other than psoriasis vulgaris that would interfere with evaluations of the effect of the study medication, as determined by the Investigator.
  • Participants who cannot discontinue the use of strong cytochrome P-450 CYP3A4 inhibitors for 2 weeks prior to Day 1 and during the study period.
  • A medical history of severe renal insufficiency, moderate to severe hepatic disorders (e.g., Child-Pugh B or C), or chronic infectious disease (e.g., hepatitis B, hepatitis C, or human immunodeficiency virus [HIV]).
  • Participants who are family members of the clinical study staff or sponsor.
