  • Systemic treatments with all other therapies than biologicals, with a potential effect on psoriasis vulgaris (e.g., corticosteroids, vitamin D analogues, retinoids, immuno-suppressants) within the 4-week period prior to randomisation
  • Subjects using one of the following topical drugs for the treatment of psoriasis within the 4 week period prior to randomisation

    • 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 2 weeks prior to randomisation

    • WHO group I-II corticosteroids
    • Topical retinoids
    • Vitamin D analogues
    • Topical immunomodulators (e.g. macrolides)
    • Anthracen derivatives
    • Tar
    • Salicylic acid
    • UVB therapy
  • 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 current diagnosis of guttate, erythrodermic, exfoliative or pustular psoriasis
  • Subjects with known or suspected hypersensitivity to component(s) of the investigational products
  • Subjects with known/suspected disorders of calcium metabolism associated with hypercalcaemia
  • Subjects with known severe hepatic and/or severe renal insufficiency
  • Subjects with any of the following conditions present on the plaque test areas: viral (e.g. herpes or varicella) lesions of the skin, fungal and bacterial skin infections, parasitic infections and atrophic skin
  • Subjects with skin manifestations on the plaque test areas in relation to syphilis or tuberculosis, rosacea, perioral dermatitis, acne vulgaris, atrophic skin, striae atrophicae, fragility of skin veins, ichthyosis, acne rosacea, ulcers and wounds
  • Subjects with any concomitant medical or dermatological disorder(s) which might preclude accurate evaluation of the psoriasis
