Eligibility Criteria

Inclusion Criteria

1. Signed and dated informed consent obtained following receipt of verbal and written information about the study prior to any trial related activities (including any wash-out period).

2. Age 18 years or above.

3. Either sex.

4. Any race or ethnicity.

5. Attending a hospital out-subject clinic or the private practice of a dermatologist for treatment of psoriasis vulgaris.

6. Clinical diagnosis of psoriasis vulgaris involving non scalp regions of the body (trunk and/or limbs) with or without involvement of the scalp.

7. At SV2 and Day 0 (Visit 1) a clinical diagnosis of psoriasis vulgaris which is:

• amenable to topical treatment with a maximum of 100 g of study medication per week, and
• of an extent of between 15 and 30% of the body surface area (BSA) excluding psoriasis on the face, genitals or skin folds.
• a disease severity on the trunk and/or limbs graded as at least moderate according to the investigator's global assessment (IGA)

8. Subjects with normal HPA axis function at SV2 including a serum cortisol concentration above 5 mcg/dL before ACTH challenge test and above 18 mcg/dL 30 minutes after ACTH challenge test.

9. Albumin-corrected serum calcium, below the upper reference limit at SV2.

10. Females of child-bearing potential must have a negative urine pregnancy test result at baseline Visit SV2 and must agree to use a highly effective method of contraception during the study. Highly effective methods are defined as ones which results in a low failure rate (less than 1% per year) such as progestin-only formulations (implants, injectables), some intra-uterine devices, or vasectomised partner. Subjects must have used the contraceptive method continuously 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 (or until study visit FU2 if applicable). 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).

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

16. Systemic treatment with therapies other than biologicals, with a possible effect on psoriasis vulgaris (e.g., retinoids, methotrexate, immunosuppressants) within 4 weeks prior to Visit 1 (Day 0) or during the study.

17. PUVA or Grenz ray therapy within 4 weeks prior to Visit 1 (Day 0) or during the study

18. UVB therapy within 2 weeks prior to Visit 1 (Day 0) or during the study.

21. Oral calcium supplements, vitamin D supplements, antacids, thiazide and/or loop diuretics, antiepileptics, diphosphonates or calcitonin within 4 weeks prior to SV2 and during the study. Note: Stable doses of oral vitamin D supplementation ≤400 IU/day is permitted provided there are no dose adjustments during the study period.

26. Systemic or topical cytochrome P450 3A4 (CYP 3A4) inhibitors (e.g., ketoconazole, itraconazole, metronidazole) within 4 weeks prior to SV2 or during the study. Topical ketoconazole within 2 weeks prior to SV2.

27. Hypoglycaemic sulfonamides within 4 weeks prior to the SV2 or during the study.

28. Antidepressant medications within 4 weeks prior to SV2 or during the study.

29. Not following nocturnal sleep patterns (e.g. night shift workers are excluded).

30. Known or suspected endocrine disorder that may affect the results of the ACTH challenge test.

34. Known or suspected severe renal insufficiency or severe hepatic disorders.

35. Known or suspected disorders of calcium metabolism associated with hypercalcaemia.

36. Any clinically significant abnormality following review of screening laboratory tests (blood and spot urine samples), physical examination or blood pressure/heart rate measurement performed at SV2.

37. Current diagnosis of guttate, erythrodermic, exfoliative or pustular psoriasis.

38.
