Exclusion criteria:

• Male who are not willing to use a local contraception (such as condom) for the entire duration of the study, and refrain from fathering a child within 3 months following the last study drug application

• Females who are pregnant, of child-bearing potential and who wish to become pregnant during the study, or who are breast feeding

• Systemic treatment with biological therapies (marketed or not marketed) with a possible effect on psoriasis vulgaris within 4 weeks (etanercept), 2 months (adalimumab, alefacept, infliximab), 4 months (ustekinumab) or 4 weeks /5 half-lives (which-ever is longer) for experimental biological products prior to randomisation and during the study

• Systemic treatments with all other therapies than biologicals, with a potential effect on psoriasis vulgaris (e.g., corticosteroids, retinoids, immunosuppressants) within the 4-week period prior to randomisation and during the study

• Subjects using one of the following topical drugs for the treatment of psoriasis within the 4 week period prior to randomisation and during the study:

• Potent or very potent (WHO group III-IV) corticosteroids

• PUVA or Grenz ray therapy

• Subjects using one of the following topical drugs for the treatment of psoriasis within two weeks prior to randomisation and during the study:

• WHO group I-II corticosteroids (except if used for treatment of scalp and/or facial psoriasis)

• Topical retinoids

• Vitamin D analogues

• Topical immunomodulators (e.g. macrolides)

• Anthracen derivatives

• Tar

• Salicylic acid

• UVB therapy

• Subjects using emollients on the target plaques within one week before randomisation and during the study

• Initiation of, or expected changes to concomitant medication that may affect psoriasis vulgaris (e.g., beta blockers, anti-malaria drugs, lithium and ACE inhibitors) within 2 weeks prior to the randomisation and during the study

• Subjects with current diagnosis of guttate, erythrodermic, exfoliative or pustular psoriasis

• Subjects with known/suspected disorders of calcium metabolism associated with hypercalcaemia based on medical history

• Subjects with a positive Hepatitis B, Hepatitis C or HIV test

• Subjects who have received treatment with any non-marketed drug substance (i.e., an agent which has not yet been made available for clinical use following registration) within the 4 week period prior to randomisation or longer, if the class of the substance requires a longer washout as defined above (e.g., biological treatments)

• Subjects with current participation in any other interventional clinical, based on interview of the subject

• Subjects with known or suspected hypersensitivity to component(s) of the investigational products

• History of any severe disease or serious current condition (based on subject interview and/or results of screening physical examination) which, in the opinion of the Investigator, would put the subject at risk by participating in the study or would interfere significantly with the evaluation of study results or the study course (e.g. cancer, severe cardiopathy, severe renal insufficiency, severe hepatic insufficiency).

• Subjects with a positive Hepatitis B, Hepatitis C or HIV test

• Subjects with any concomitant medical or dermatological disorder(s) which might preclude accurate evaluation of the psoriasis on the test areas

• Subjects foreseeing an intensive solar exposure during the study (UV radiation, etc.) or having been exposed within two weeks preceding the screening visit

• Subjects with any contraindication to skin biopsy procedures: e.g., allergy to local anaesthetics, topical antiseptics (chlorhexidine), bleeding tendency, treatment with anticoagulant drugs, history of poor wound healing, and history of vasovagal hypotension or syncope.
