The systemic effect of Taclonex® Ointment in extensive psoriasis was investigated in the study described above. In this study, the serum levels of calcipotriene and betamethasone dipropionate and their major metabolites were measured after 4 weeks (maximum recommended duration of treatment) and also after 8 weeks of once daily application of Taclonex® Ointment on the body in combination with Taclonex Scalp® Topical Suspension on the scalp. Both calcipotriene and betamethasone dipropionate were below the lower limit of quantification in all serum samples of the 34 subjects evaluated. However, one major metabolite of calcipotriene (MC1080) was quantifiable in 10 of 34 (29.4%) subjects at week 4 and in five of 12 (41.7%) subjects at week 8. The major metabolite of betamethasone dipropionate, betamethasone 17-propionate (B17P) was also quantifiable in 19 of 34 (55.9%) subjects at week 4 and seven of 12 (58.3%) subjects at week 8. The serum concentrations for MC1080 ranged from 20-75 pg/mL. The clinical significance of this finding is unknown.
Calcipotriene metabolism following systemic uptake is rapid and occurs in the liver. The primary metabolites of calcipotriene are less potent than the parent compound.
Calcipotriene is metabolized to MC1046 (the alpha,beta-unsaturated ketone analogue of calcipotriene), which is metabolized further to MC1080 (a saturated ketone analogue). MC1080 is the major metabolite in plasma. MC1080 is slowly metabolized to calcitroic acid.
Betamethasone dipropionate is metabolized to betamethasone 17-propionate and betamethasone, including the 6beta-hydroxy derivatives of those compounds by hydrolysis. Betamethasone 17-propionate (B17P) is the primary metabolite.
When calcipotriene was applied topically to mice for up to 24 months at dosages of 3, 10 and 30 mcg/kg/day (corresponding to 9, 30 and 90 mcg/m2 /day), no significant changes in tumor incidence were observed when compared to control.
In a study in which albino hairless mice were exposed to both ultra-violet radiation (UVR) and topically applied calcipotriene, a reduction in the time required for UVR to induce the formation of skin tumors was observed (statistically significant in males only), suggesting that calcipotriene may enhance the effect of UVR to induce skin tumors.
Long-term animal studies have not been performed to evaluate the carcinogenic potential of betamethasone dipropionate.
Calcipotriene did not elicit any genotoxic effects in the Ames mutagenicity assay, the mouse lymphoma TK locus assay, the human lymphocyte chromosome aberration test, or the mouse micronucleus test.
Betamethasone dipropionate did not elicit any genotoxic effects in the Ames mutagenicity assay, the mouse lymphoma TK locus assay, or in the rat micronucleus test.
Studies in rats with oral doses of up to 54 mcg/kg/day (324 mcg/m2 /day) of calcipotriene indicated no impairment of fertility or general reproductive performance.
Studies in male rats at oral doses of up to 200 mcg/kg/day (1200 mcg/m2 /day), and in female rats at oral doses of up to 1000 mcg/kg/day (6000 mcg/m2 /day), of betamethasone dipropionate indicated no impairment of fertility.
In an international, multi-center, double-blind, vehicle- and active-controlled, parallel-group study, 1603 subjects with mild to very severe psoriasis vulgaris on trunk and limbs were treated once daily for 4 weeks. Subjects were randomized to one of four treatment arms: Taclonex® Ointment, calcipotriene hydrate 50 mcg/g in the same vehicle, betamethasone dipropionate 0.64 mg/g in the same vehicle, and vehicle alone. The mean age of the subjects was 48.4 years and 60.5% were male. Most subjects had disease of moderate severity at baseline.
Efficacy was assessed as the proportion of subjects with absent or very mild disease according to the Investigator’s Global Assessment of Disease Severity at end of treatment (4 weeks). “Absent” disease was defined as no evidence of redness, thickness, or scaling. “Very mild disease” was defined as controlled disease, but not entirely cleared: lesions with some discoloration with absolutely minimal thickness, i.e. the edges to the lesions(s) could just be felt. Table 3 contains the response rates for this trial.

|Absent or very mild disease||48.0%||16.5%||26.3%||7.6%|
In addition to the pivotal study (N = 490), four randomized, double-blind, vehicle- or active-controlled, parallel-group studies were conducted and provided supportive evidence of efficacy. These studies included a total of 1058 subjects treated with Taclonex® Ointment once daily for up to 4 weeks.
