| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial |

| Valutare la sicurezza del trattamento fino a 26 settimane con calcitriolo da 3 mcg/g unguento quando usato due volte al giorno, senza occlusione, per trattare soggetti pediatrici (di età compresa tra i 2 e i 17 anni) affetti da psoriasi a placche.
 |  | 
| E.2.2 | Secondary objectives of the trial |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| - Male or female pediatric subjects (2 to 17 years of age, inclusive) at Screening. 
 - The subject has a clinical diagnosis of stable mild to moderate plaque type psoriasis.
 |  
| - Soggetti pediatrici di sesso maschile o femminile (da 2 a 17 anni di età inclusi) alla selezione. - Il soggetto ha una diagnosi clinica di psoriasi a placche stabile da lieve a moderata.
 |  | 
| E.4 | Principal exclusion criteria | 
| - Subjects with guttate psoriasis, pustular psoriasis, erythrodermic psoriasis or active infection (i.e., an infection associated with fever, swollen lymph nodes, and/or signs of localized inflammation of tissue and/or joints). 
 - Subject has hypercalcemia (serum albumin-adjusted calcium level above the upper normal range) at Screening.
 
 - Subjects with known or suspected disorders of calcium metabolism.
 
 |  
| - Soggetti affetti da psoriasi guttata, psoriasi eritrodermica o infezione attiva (ad esempio, un'infezione associata a febbre, ingrossamento dei linfonodi e/o segni di infiammazione localizzata del tessuto e/o delle articolazioni).
 - Il soggetto presenta ipercalcemia (livelli sierici del calcio corretti in relazione al livello di albumina superiori al range di normalità)
 alla selezione.
 - Soggetti con disturbi del metabolismo del calcio noti o sospetti.
 |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Efficacy endpoints: - Percentage of subjects with an IGA Score of 0 (clear) or 1 (almost clear).
 - Change from Baseline in Pruritus.
 - Change from Baseline in % BSA.
 Safety endpoints:
 - include Serum albumin-adjusted calcium, urine calcium:creatinine ratio, phosphorus, and PTH.
 |  
| Endpoints di efficacia: - Percentuale di soggetti con un punteggio IGA equivalente a 0 (chiaro) o 1 (quasi chiaro). - Variazioni nel prurito rispetto al basale. - Variazioni della %BSA rispetto al basale. Endpoints sulla sicurezza: - Calcio sierico corretto in relazione al livello di albumina, rapporto calcio: creatinina nelle urine, fosforo e PTH. |  |
