A Study of Calcitriol BID Topical Treatment in Adolescents With Plaque Psoriasis

February 16, 2021 updated by: Galderma R&D

PK and PD of Calcitriol Following Twice Daily Application of Calcitriol 3 µg/g Ointment Under Conditions of Maximal Use in Adolescents With Plaque Psoriasis

This is an open-label, multicenter study to assess the systemic exposure to calcitriol in the adolescent population. Calcitriol 3µg/g ointment (2 mg/cm² per application) is to be applied twice daily to involved skin (10 - 35% BSA involved, excluding face, scalp and intertriginous areas) for 56 days (8 weeks). Full Pharmacokinetic (PK) and Pharmacodynamic (PD) profile will be collected during the first 3 weeks of the study; safety and efficacy data will be collected for the 8 weeks of the treatment.

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.

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

12 years to 17 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of chronic plaque psoriasis
  • 10 - 35% BSA of involved skin
  • Age 12 - 17

Exclusion Criteria:

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.
