Brief Summary

Atopic eczema causes significant disease burdens worldwide. Some studies reported gastrointestinal symptoms in eczema patients which could be related to gut microbiota change. A unique gastrointestinal microflora pattern has also been observed in atopic dermatitis patients when compared with healthy controls. To date, no adult formula is specific for alleviating atopic eczema-related symptoms (especially through change of gut microbiota) for adults. The investigators hypothesize that the gut microbiota of adults with atopic eczema can be modulated to decrease the severity of atopic eczema-related symptoms. A pilot study is proposed to assess the effect and safety of SIM05 on atopic eczema severity and gut microbiome of adults with atopic eczema.

Outcome Measures

Primary Outcomes (1)

  • Change in Eczema Area and Severity Index (EASI) across 16 weeks.

    The change of score in Eczema Area and Severity Index. A score of 0 indicates clear or no eczema, 0.1 to 1.0 indicates almost clear, 1.1 to 7 indicates mild disease, 7.1 to 21 indicates moderate disease, 21.1 to 50 indicates severe disease, and greater than 51 indicates very severe disease.

    16 weeks

Secondary Outcomes (5)

  • Percentage of subjects achieving 50% and 75% reduction in EASI (EASI-50, EASI-75).

    16 weeks

  • Change in pruritus numerical rating scales (pruritus-NRS) across 16 weeks.

    16 weeks

  • Changes in faecal microbial profiling across 16 weeks.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults age 18 or older physician-diagnosed atopic eczema;
  • Agree to sign the informed consent form

You may not qualify if:

  • Adults with other documented chronic and clinically significant dermatologic diseases that may interfere with the evaluation of cutaneous signs and symptoms. Common conditions such as acne are permissible.
  • Adults with atopic eczema who have taken antibiotics within one months prior to recruitment.
  • Adults with atopic eczema who require systemic immunosuppressive treatments (e.g. azathioprine, methotrexate, mycophenolate mofetil, cyclosporine, biologics) within three months prior to recruitment, or who are taking systemic steroids within one month.
