Last updated: March 25, 2015
Last verified: March 2015
This study will compare efficacy and safety of once daily treatment of calcipotriol plus betamethasone dipropionate gel (LEO 80185) with tacalcitol ointment and LEO 80185 vehicle alone in subjects with psoriasis vulgaris. Subjects will be treated for up to 8 weeks followed by an observation period of up to 8 weeks to investigate the occurence and the time to relapse and occurence of rebound after discontinuation of the investigational products. Only subjects with "controlled disease" will be considered for this observation phase of the study. "Controlled disease" is defined as "Clear" or "Almost Clear" severity category based on Investigator's global assessment (IGA).

Condition Intervention Phase
Psoriasis Vulgaris Drug: calcipotriol and betamethasone (LEO 80185 gel) Drug: LEO 80185 vehicle Drug: Tacalcitol ointment Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: A Phase 3 Study Comparing a Gel Containing Calcipotriol 50 mcg/g Plus Betamethasone 0.5 mg/g (as Dipropionate) With Tacalcitol Ointment (4 mcg/g) and Gel Vehicle, Used Once Daily in the Treatment of Psoriasis Vulgaris

Primary Outcome Measures:
  • Subjects With "Controlled Disease" ("Clear" or "Almost Clear" Disease) According to Investigator's Global Assessment of Disease Severity at Week 8 [ Time Frame: Week 8 ]

Secondary Outcome Measures:
  • Subjects With "Controlled Disease" According to the Investigator's Global Assessment of Disease Severity at Week 4 [ Time Frame: Week 4 ]
  • The Percentage Change in PASI From Baseline to Week 8 [ Time Frame: Baseline, Week 4 and 8 ]
    PASI is Psoriasis Area and Severity Index and is based on the investigator's assessment of extent and severity of the disease. It can range from 0 (best) to 64.8 (worst).

  • Subjects With Relapse During the Study [ Time Frame: Week 8-16 ]
    Among subjects with controlled disease at week 8 relapse was defined as PASI exceeding the baseline PASI value minus 50% of the reduction in PASI obtained from the baseline visit to the last on-treatment visit

  • Subjects With Rebound During the Study [ Time Frame: Week 8-16 ]

Enrollment: 458
