6.1 Clinical

Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Calcitriol Ointment was studied in two vehicle-controlled trials and one open label trial, resulting in 743 subjects exposed to Calcitriol Ointment. Table 1 describes adverse events in subjects treated with Calcitriol Ointment twice daily for 8 weeks. The population included subjects ages 13 to 87 years, males and females, Caucasians and non-Caucasians; with mild to moderate chronic plaque psoriasis. Table 1. Selected Adverse Events Occurring in at least 1% of Subjects in the Two Pooled Vehicle-Controlled Trials Calcitriol Ointment (n=419) Vehicle Ointment (n=420) Discomfort Skin 3% 2% Pruritus 1% 1% Among subjects having laboratory monitoring, hypercalcemia was observed in 24% (18/74) of subjects exposed to active drug and in 16% (13/79) of subjects exposed to vehicle, however the elevation were less than 10% above the upper limit of normal The open label study enrolled 324 subjects with psoriasis who were then treated for up to 52 weeks and included 239 subjects exposed for 6 months and 116 subjects exposed for one year. Adverse events reported at a rate of greater than or equal to 3% of subjects treated with Calcitriol Ointment were lab test abnormality (8%), urine abnormality (4%), psoriasis (4%), hypercalciuria (3%), and discomfort of skin (3%). Kidney stones were reported in 3 subjects and confirmed in two.

6.2 Postmarketing

Experience The following adverse reactions have been identified during the world-wide post-approval use of Calcitriol Ointment: acute blistering dermatitis, erythema,and skin burning sensation. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
