Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will be done using treatment codes generated by an independent statistician. Placebo and RCM-106 capsules will be made to be identical in appearance and scent, and will be pre-packaged identically. The codes and labeling will be recorded in a password protected computer program.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An independent statistician will be responsible for randomisation and ensure the comparability in both groups. Block randomised sequences according to diseases severity will be generated using a computer software.
Masking / blinding

Summary
Brief summary
Atopic dermatitis, or eczema, is a chronic, inflammatory, itchy skin disease that affects 15-30% of children and 2-10% of adults. This condition is highly distressing and affects the quality-of-life of its sufferers and their families. Unfortunately, there is currently no adequate treatment for atopic dermatitis.
Traditional Chinese medicine has had a long history of treating various conditions, including skin conditions such as atopic dermatitis. However, evidence is lacking. In attempt to find a better form of management for atopic dermatitis, we have formulated a new Chinese herbal formula, RCM-106, using Western and Chinese medicine theories. It is anticipated that RCM 106 would be able to reduce the severity of atopic dermatitis and possibly improve the quality-of-life of sufferers.
The efficacy and safety of RCM-106 will be evaluated in a randomised, double-blind, placebo-controlled clinical trial. Participants of the trial have a 50-50 chance of being allocated to receive RCM-106 capsules or the inactive placebo capsules for 8 weeks. The progression of participants’ atopic dermatitis will then be observed and recorded to see how well RCM-106 works. Positive results from the trial may result in a better form of treatment for atopic dermatitis.
