  • Systemic treatment with biological therapies whether marketed or not with a possible effect on psoriasis vulgaris within the following time periods prior to randomisation:

    • Etanercept - 4 weeks
    • Adalimumab, alefacept, infliximab - 2 months
    • Ustekinumab - 4 months
  • Systemic treatment with all other therapies (other than biologics) with a possible effect on psoriasis vulgaris (e.g.corticosteroids, retinoids, immunosuppressants, methotrexate, cyclosporin or fumaric acid) within 4 weeks prior to randomisation
  • PUVA therapy within 4 weeks prior to randomisation
  • UVB therapy within 2 weeks prior to randomisation
  • Any topical treatment (except for emollients/ medicated shampoo) within 2 weeks prior to randomisation
  • Initiation of, or changes to concomitant medication that could affect psoriasis vulgaris (e.g. beta-blockers, anti-malaria drugs, lithium) 2 weeks prior to randomisation and during the study
  • Current diagnosis with erythrodermic, exfoliative or pustular psoriasis
  • Other current skin conditions that may confound the evaluation of psoriasis vulgaris as judged by the Investigator
  • Generally in good health and does not have any clinically significant cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal, haematologic, or gastrointestinal disease, immunologic insufficiency, or other major diseases or current condition which, in the opinion of the Investigator, would put the subject at risk by participating in the study
  • Current active tuberculosis or latent tuberculosis
  • Planned exposure to the sun during the study that may affect psoriasis vulgaris
  • Known malignancy or history of malignancy (other than cervical carcinoma in situ, basal cell or squamous cell carcinoma) within the 5 year period prior to randomisation
  • Live vaccination within the 4 weeks prior to randomisation
  • Males who do not agree to use adequate contraception during the study (including follow-up) to ensure their partner does not become pregnant
  • Known or suspected hypersensitivity to component(s) of the investigational product
