Eligibility criteria:

        Inclusion Criteria:

          -  Signed and dated informed consent obtained prior to any trial related activities
             (including any washout period).

          -  Aged 18 years or above

          -  Either sex

          -  Any race or ethnicity

          -  Attending a hospital outpatient clinic or the private practice of a board certified
             dermatologist.

          -  Clinical diagnosis of stable plaque psoriasis vulgaris of at least 6 months duration
             involving the non-scalp regions of the body (trunk and/or limbs) amenable to treatment
             with a maximum of 100 g of topical medication per week.

          -  An investigator's global assessment of disease severity (IGA) of mild or moderate on
             the body (trunk and/or limbs) at Day 0 (Visit 1).

          -  A minimum modified Psoriasis Area and Severity Index (PASI) score for extent of 2 in
             at least one body region (i.e. psoriasis affecting at least 10% of arms, and/or 10% of
             trunk, and/or 10% of legs)

          -  Females of childbearing potential must have a negative pregnancy test at Day 0 (Visit
             1).

          -  Females of childbearing potential must agree to use a highly effective method of birth
             control during the study. A highly effective method of birth control is defined as one
             which results in a low failure rate (less than 1% per year) such as implants,
             injectables, combined oral contraceptives, some intrauterine devices, sexual
             abstinence or vasectomised partner. The patients must have used the contraceptive
             method continually for at least 1 month prior to the pregnancy test, and must continue
             using the contraceptive method for at least 1 week after the last application of study
             medication. A female is defined as not of child-bearing potential if she is
             postmenopausal (12 months with no menses without an alternative medical cause), or
             surgically sterile (tubal ligation/section, hysterectomy or bilateral ovariectomy).

          -  Able to communicate with the investigator and understand and comply with the
             requirements of the study.

                  to randomisation

          -  Systemic treatment with all other therapies with a possible effect on psoriasis
             vulgaris (e.g., corticosteroids, retinoids, methotrexate, cyclosporine and other

          -  Planned initiation of, or changes to, concomitant medication that could affect
             psoriasis vulgaris (e.g. beta blockers, anti-malarials, lithium, ACE inhibitors)

             vulgaris.

          -  Previously randomised in this study.
