Clinical Studies Experience
VECTICAL (calcitriol ointment) Ointment was studied in two vehicle-controlled studies (419 subjects), and in one open label study (324 subjects). The table below describes exposure to VECTICAL (calcitriol ointment) Ointment in 743 subjects, including 239 exposed for 6 months and 116 exposed for one year.
Four hundred and nineteen subjects were treated with VECTICAL (calcitriol ointment) Ointment twice daily for 8 weeks. The population included subjects ages 13 to 87, males (284) and females (135), Caucasians (372) and non-Caucasians (47); with mild (105) to moderate (313) chronic plaque psoriasis.
Selected Adverse Events Occurring in at least 1% of Subjects
in the Two Pooled Vehicle-Controlled Studies
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 elevations were less than 10% above the upper limit of normal [see WARNINGS AND PRECAUTIONS]
The open label study enrolled 324 subjects with psoriasis who were then treated for up to 52 weeks. Adverse events reported at a rate of greater than or equal to 3% of subjects treated with VECTICAL (calcitriol ointment) Ointment were lab test abnormality (8%), urine abnormality (4%), psoriasis (4%), hypercalciuria (3%), and pruritus (3%). Kidney stones were reported in 3 subjects and confirmed in two.
The following adverse reactions have been identified during world-wide post-approval use of VECTICAL (calcitriol ointment) Ointment: acute blistering dermatitis, erythema, pruritus, skin burning sensation, and skin discomfort. 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.
