February 5, 2020 updated by: Castle Creek Pharmaceuticals, LLC

A 4 Day, Randomized Study to Evaluate the Potential of CCP-020 (Diacerein 1%) Topical Ointment to Induce a Phototoxicity Skin Reaction in Healthy Subjects, Using a Controlled Photopatch Test

This study was designed to assess the phototoxic potential of diacerein 1% ointment when application is followed by light exposure.

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 was a single-center, randomized, within-subject comparison of diacerein 1% ointment and vehicle ointment applied to 2 sites on opposite sides of the the infrascapular area of the back under occlusive patch conditions for approximately 24 (±2) hours. Product was applied according to the randomization scheme in an amount of 0.2 mL, once during the study.

Patches were removed and 1 of the skin sites for each product was irradiated and 1 remained non-irradiated. The irradiated and non-irradiated sites were compared with each other and with an untreated irradiated control site.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Description

Key Inclusion Criteria:

  • Is a healthy male or female (to be confirmed by medical history);
  • Is 18 years of age or older;
  • In the case of a female of childbearing potential, is using two acceptable forms of birth control;

Experimental: Single Cohort (Healthy Volunteers)
Single cohort received diacerein 1% ointment
Drug: Diacerein 1% ointment
Diacerein 1% ointment and vehicle ointment were applied on Day 1 at two randomly assigned skin sites on each side of the lower thoracic area of the back according to a randomization scheme. One side of the back was irradiated on Day 2, including an untreated irradiated control site, and the other side was to remain non-irradiated.

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
Observed Phototoxicity
Time Frame: Days 3 and 4 (24 and 48 hours post site irradiation procedure)
The mean of the total irritation scores 24 and 48 hours post the site irradiation procedure. ( i.e. Day 3 and 4) Total Irritation Score is a visual score summing the degree of erythema and edema. Minimum score= 0; Maximum score = 5; higher score = worse outcome.
Days 3 and 4 (24 and 48 hours post site irradiation procedure)
