Eczema icon large

Atopic Dermatitis (AD) is a chronic, relapsing inflammatory disease of the skin affecting up to 20% of children and 3% of adults with an increasing prevalence in industrialised countries.

Atopic Dermatitis (AD) or Eczema is a multifactorial disease and its pathophysiology has been linked to (genetic) modification of skin barrier function, bacterial (e.g. Staphylococcus aureus) colonisation and inflammation (Ref 7, 10, 11). It has a lifetime prevalence of 7% (Ref 7).

AD patients complain of dry, inflamed and itchy skin that typically affects the face, inside of the elbows and back of the knees. The current US cost of treatment for atopic dermatitis amounts to $12 billion per year (Ref 7). 75% of the costs are indirect costs e.g. over the counter remedies, lubricants and days lost from work. Such treatments can help in symptom relief but do not tackle the underlying disease. Current second line treatments are topical corticosteroids with third line topical calcineurin inhibitors. These treatments are unpopular because of their significant side effects. What patients want is a safe, effective treatment that can be used in all age groups.

Blueberry Therapeutics is developing a new treatment using a potent, selective inhibitor (BB2702) of one of the key inflammatory pathways in AD. Together with our effective bacteriocidal nanopolymer delivery system this treatment will address two of the three key mechanisms of AD: inflammation, and bacterial colonisation.
