Primary Outcome Measures:
  • Change From Baseline in Modified Psoriasis Area and Severity Index (mPASI) [ Time Frame: Baseline to Week 4 ] [ Designated as safety issue: No ]

    The primary response criterion was the percentage change in m-PASI from baseline to Week 4.

    The extent of and severity of redness, thickness and scaliness of psoriasis were recorded for each of three regions (arms, trunk and legs) and these were used to calculate mPASI using the following formula:

    Arms: 0.2(R+T+S)E = X Trunk: 0.2(R+T+S)E = Y Legs: 0.2(R+T+S)E = Z where R = score for redness (using a scale from 0 to 4, where o is non signs and 4 is the most severe signs) T = score for thickness (using a scale from 0 to 4, where o is non signs and 4 is the most severe signs) S = score for scaliness (using a scale from 0 to 4, where o is non signs and 4 is the most severe signs) E = score for extent (using a scale from 0 to 6, where 0 is no involvement and 6 is 90-100% involvemnet) The sum of X + Y + Z gave the total m-PASI, which could range from 0 to 64.8.



Secondary Outcome Measures:
  • Change From Baseline in Target Lesion Assessment [ Time Frame: Baseline to Week 4 ] [ Designated as safety issue: No ]

    Percentage change in composite severity score of the target lesion from baseline to Week 4.

    At Visit 1, the investigator selected a target lesion. Location was recorded as trunk, limb excluding elbow and/or knee.

    At Visits 1-4, the investigator assessed the severity of the target lesion for each sign (redness, thickness and scaliness) on a scale from 0 to 8 where 0 is no signs of redness, thickness or scaliness and 8 is the most severe signs of redness, thickeness or scaliniess.

    The individual scores for redness, thickness and scaliness were added together to give a single composite score for severity of the target lesion which could range from 0 to 24. The percentage change in the composite severity score from baseline to each visit was also calcutated.


  • Physician's Global Assessment of Psoriasis [ Time Frame: Week 4 ] [ Designated as safety issue: No ]

    Subjects with 'clear' or 'almost clear' disease by physician's global assessment on the following 6 point scale: clear, almost clear, mild, moderate, severe, very severe.

    The assessment represents the average lesion severity on the trunk and limbs. The assessment was based on the condition of the disease at the time of evaluation, and not in relation to the condition at a previous visit.


  • Change in mPASI From Baseline to Week 1 [ Time Frame: Baseline to Week 1 ] [ Designated as safety issue: No ]
    The extent of and severity of redness, thickness and scaliness of psoriasis were recorded for each of three regions (arms, trunk and legs) and these were used to calculate mPASI. The m-PASI could range from 0 to 64.8. The least severe outcome is 0 and the most severe outcome is 64.8

Detailed Description:

LEO 90105 ointment contains both calcipotriol and betamethasone dipropionate. It has been approved for the treatment of psoriasis in more than 60 centres, including most European countries, the US, China, Korea and Taiwan. This trial will investigate its safety and efficacy in the treatment of Japanese subjects with psoriasis.

  Eligibility

Criteria

Inclusion Criteria:

  • Subjects having understood and signed a written informed consent form prior to any study related procedures being carried out.
  • Japanese subjects.
  • 20 years of age or above.
  • Either sex.
  • Clinical diagnosis of psoriasis vulgaris amenable to topical treatment, involving arms and/or trunk and/or legs.
  • A minimum m-PASI (Modified Psoriasis Area and Severity Index) 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).

  • Psoriasis vulgaris on the trunk/limbs (excluding psoriasis on the genitals/skin folds) of not more than 30% body surface area (BSA).
  • A target lesion of a minimum of 5 cm at its longest axis and preferably not located on an elbow or knee, scoring at least 3 for each of redness, thickness and scaliness, and at least 10 in total by the physician's assessment of severity of the target lesion - A physician's global assessment of disease severity of psoriasis on trunk/limbs of mild, moderate, severe or very severe.
  • Females of childbearing potential must have a negative result for a urine pregnancy test at Day 0 (Visit 1) and must agree to use an adequate method of birth control, as judged by the (sub)investigator, during the study. The contraceptive method should have started an adequate amount of time before the pregnancy test, which is dependent on the partic-ular method used and as judged by the (sub)investigator, and must continue 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 alter-native medical cause) or surgically sterile (tubal ligation/section, hysterectomy or bilateral ovariectomy).
