Assess the Potential for Adrenal Suppression and Systemic Drug Absorption Following Multiple Dosing With DFD-06

March 5, 2024 updated by: Primus Pharmaceuticals

An Open Label, Multicenter Study to Assess the Potential for Adrenal Suppression and Systemic Drug Absorption Following Multiple Dosing With DFD-06 in Pediatric Subjects With Moderate to Severe Plaque Psoriasis

The purpose of this study is to evaluate the potential of DFD-06 to suppress the hypothalamic-pituitary-adrenal (HPA) axis when applied twice daily for 15 days.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a 15-day, single arm, multicenter, multi-dose, open-label, two stage, sequential study. In the first stage, subjects who are at least 12 years of age and not more than 16.9 years (16 years and 11 months) of age with moderate to severe plaque psoriasis will be treated with DFD-06 (at least 20 completed subjects). In the second stage subjects who are at least 6 years of age and not more than 11.9 years (11 years and 11 months) of age with moderate to severe plaque psoriasis will be treated with DFD-06 (at least 20 completed subjects). An attempt will be made to enroll subjects throughout the age range of each cohort including the lower age range. DFD-06 will be applied twice daily to all affected areas on the body excluding face, scalp, groin, axillae and other intertriginous areas. Subjects must have ≥10% Body Surface Area (BSA) treated to achieve maximal use exposure.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

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

6 years to 17 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Subjects and the parent or legal guardian understand the study procedures and agree to participate by giving assent and written informed consent, respectively. Subject's parent or legal guardian must be willing to authorize use and disclosure of protected health information collected for the study.
  • Subjects must be at least 6 years and not more than 16.9 years of age, with body weight greater than or equal to 45 pounds at Screening.
  • Subjects must present with a clinical diagnosis of stable (at least 3 months) plaque psoriasis.
  • Subjects with psoriasis involving ≥10% Body Surface Area (BSA), not including the face, scalp, groin, axillae and other intertriginous areas at the Baseline Visit.
  • Subjects must have an Investigator Global Assessment (IGA) grade of at least 3 (moderate) at the Baseline Visit.

Exclusion Criteria:

  • Subject has a current diagnosis of unstable forms of psoriasis including guttate, erythrodermic, exfoliative or pustular psoriasis.
  • Subject has a history of organ transplant requiring immunosuppression, HIV, or other immunocompromised state.
  • Subject has received treatment for any type of cancer within 5 years of the Baseline Visit except skin cancer and cervical cancer (in situ) are allowed if at least 1 year before the Baseline Visit.
  • Subject has a history or presence of intracranial hypertension.
  • Subject has had prolonged exposure to natural or artificial sources of ultraviolet radiation within 30 days prior to the initiation of treatment or is intending to have such exposure during the study that is thought by the investigator to likely modify the subject's disease

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Subjects With HPA Axis Suppression at Day 15
Time Frame: Day 15
The percentage of subjects with abnormal cortisol response for ACTH stimulation test at Day 15 (cortisol level ≤18 µg/dL at 30 minutes post stimulation) is the primary variable
Day 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Improvement in IGA Grade From Baseline
Time Frame: Baseline up to Day 15
Numbers of subjects with improvements by at least 1 pint in IGA grade will be provided as descriptive statistics.
