E.2.1 | Main objective of the trial |
The primary objective is to evaluate the safety of once daily use of calcipotriol (50 mcg/g) plus betamethasone (0.5 mg/g) (as dipropionate) gel in adolescent subjects (aged 12 to 16 years, 11 months) with scalp and body psoriasis. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective is to evaluate the efficacy of once daily use of calcipotriol (50 mcg/g) plus betamethasone (0.5 mg/g) (as dipropionate) gel in adolescent subjects (aged 12 to 16 years, 11 months) with scalp and body psoriasis. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria for subjects enrolled in EU
1. Signed informed consent given by parent(s), or legal guardian(s), or by the subject (according to national law) following their receipt of verbal and written information about the trial.
2. Subjects will receive verbal and written information and will provide written assent to the trial.
3. Subjects 12 to 16 years, 11 months of age.
4. Either sex.
5. Any race or ethnicity.
6. Clinical signs of psoriasis vulgaris on both the scalp and body (trunk and/or limbs).
7. At SV2 and Visit 1, a clinical diagnosis of scalp and body (trunk and/or limbs) psoriasis which is:
a. of an extent of 10 to 35% of the body surface area (excluding psoriatic lesions of the face and sensitive areas. Sensitive areas include armpits, groin, under the breasts and in other skin folds around the genitals and buttocks), and
b. of at least moderate severity according to the investigator’s global assessment of disease severity on the body, and
c. for subjects aged 12 to < 15 years with a BSA ≤ 1.3 m2, amenable to topical treatment with a maximum of 55 g of investigational product per week, and
d. for subjects aged 12 to < 15 years with a BSA > 1.3 m2, amenable to topical treatment with a maximum of 75 g of investigational product per week, and
e. for subjects aged 15 to 16 years, 11 months with a BSA ≤ 1.7 m2, amenable to topical treatment with a maximum of 75 g of investigational product per week, and
f. for subjects aged 15 to 16 years, 11 months with a BSA > 1.7 m2, amenable to topical treatment with a maximum of 100 g of investigational product per week.
8. A serum albumin-corrected calcium below the upper reference limit at SV2.
9. Females of child-bearing potential must have a negative urine pregnancy test result and must agree to use a highly effective method of contraception during the trial. Highly effective methods are defined as ones which result in a low failure rate (less than 1% per year) such as progestin-only formulations (implants, injectables, or “mini-pill” in combination with a barrier method), some intra-uterine devices, double barrier methods (e.g. cervical cap and condom), tubal ligation/section, sexual abstinence or vasectomised partner. The patients must have used the contraceptive method 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 investigational product. A female is defined as not of child-bearing potential if she is premenarchal, postmenopausal or surgically sterile (hysterectomy or bilateral ovariectomy).
10. Subjects fulfilling national requirements/law for participation in this trial.
11. At SV2 and Visit 1, a clinical diagnosis of scalp psoriasis which is:
a. more than or equal to 10% of the scalp area, and
b. of at least moderate severity according to the investigator’s global assessment of disease severity on the scalp.

6. Systemic calcium, vitamin D supplementation > 400 IU/day, antacids, diuretics, antiepileptics, diphosphonates or calcitonin within 4 weeks prior to SV2 or during the trial. (note: stable doses of vitamin D supplementation ≤ 400 IU/day is permitted provided there are no dose adjustments during the study period).
7. Planned initiation of, or changes to, concomitant medication that could affect psoriasis (e.g., betablockers, chloroquine, lithium, ACE inhibitors) during the trial.
8. Current diagnosis of guttate, erythrodermic, exfoliative or pustular psoriasis.

12. Known or suspected severe renal insufficiency or severe hepatic disorders.
13. Known or suspected disorders of calcium metabolism associated with hypercalcaemia.

18. Subjects or parent(s) or legal guardian(s) known or suspected of being unlikely to comply with the Clinical Trial Protocol (e.g., alcoholism, drug dependency or psychotic state).
