Transcriptomic Study of ER 4017 Topical Application in Elderly Subject

January 6, 2009 updated by: L'Oreal

The stratum corneum (SC) is the superficial layer of the epidermis situated at the interface between the body and its outside environment. Its strategic position confers it a crucial role of protection against aggressions. After disruption, the kinetic of cutaneous barrier is slower in elderly comparatively to young subjects.

The purpose of this study is to investigate, by characterizing molecular events, the effectiveness of ER4017 (Hydroxypropyltetrahydropyrantriol) to restore kinetic barrier function after acute disruption of stratum corneum in ederly subjects.

10 male volunteers aged from 60 to 75 years are randomized to receive topical application of ER4017 versus placebo on skin inner forearms twice a day during 3 months. After sequential selloptape strips, epidermal samples of treated and control skin are removed under local anesthesia, using a dermatome. Differential gene expression analysis is performed using micro array techniques and quantitative RT-PCR.

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

Structural modifications of the superficial dermis during the aging process associated to alterations in the GAG- and PG profile appear to impact the quality of the dermal epidermal junction (DEJ). Previous biological and clinical evaluations of ER4017, a C-glycoside biomimetic of xylose, showed its capacity to stimulate GAG- and PG synthesis and to improve morphogenesis of the whole DEJ.

The aim of the study is to investigate the gene expression in human epidermis treated with ER4017 following sequential sellotapes strips after a 3 months ER4017 topical application. For this purpose, the modulation of gene expression is determined using a cDNA microarray technology. Stratum corneum disruption is performed following 3 months topical application on skin inner forearms. All the experiments are performed in 10 elderly healthy men. Volunteers are clinically and biophysically evaluated at baseline and then at monthly intervals or at 3 months respectively.

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
