Study start date: November 1, 2003Actual date on which the first participant was enrolled.

Nanocrystalline silver (very small particles of silver) is the active ingredient in Acticoat dressings, which have been approved for the treatment of burns and other wounds. Silver has been used for decades as an effective antimicrobial agent. In animal studies, nanocrystalline silver cream (NPI) has also demonstrated anti-inflammatory activity. Thus, nanocrystalline silver cream is being evaluated in the treatment of inflammatory skin conditions such as atopic dermatitis (eczema). Approximately 180 study subjects with a definitive diagnosis of mild to moderate eczema will be enrolled in this study. Subjects will be randomly assigned to treatment with placebo, 0.5% NPI or 1% NPI for the 6-week treatment period. Assessments of treatment effect and safety will be performed weekly. Upon completion of the study, subjects may be eligible for 12 weeks of open-label treatment with 1% NPI.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
180 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the interventions assigned to participants is kept confidential
Neither participants nor researchers know who is receiving which treatment. This is the most rigorous way to reduce bias, ensuring that expectations do not influence the results.

Other Ways to Mask Information
Open-label: Everyone knows which treatment is being given.
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.
