Clinical Trials Experience
Clinical Trials Conducted In Subjects 18 Years And Older With Plaque Psoriasis
The data described below reflect exposure to Taclonex® Ointment in 2448 subjects with plaque psoriasis, including 1992 exposed for 4 weeks, and 289 exposed for 8 weeks. Taclonex® Ointment was studied primarily in placebo- and active-controlled trials (N = 1176, and N = 1272, respectively). The population was 15-97 years old, 61% males and 39% females, mostly white (97%) and had a baseline disease severity ranging from mild to very severe. Most subjects received once daily application, and the median weekly dose was 24.5 g.
The percentage of subjects reporting at least one adverse event was 27.1% in the Taclonex® Ointment group, 33.0% in the calcipotriene group, 28.3% in the betamethasone group, and 33.4% in the vehicle group.

For subjects who reported lesional/perilesional adverse events, the median time to onset was 7 days for Taclonex® Ointment, 7 days for calcipotriene, 5 days for betamethasone dipropionate, and 3 days for vehicle.
Other less common reactions (less than 1% but more than 0.1%) were, in decreasing order of incidence, folliculitis, rash papular, rash pustular, and skin hypopigmentation. Skin atrophy, telangiectasia and skin hyperpigmentation were reported infrequently (0.1%).
In a separate trial, subjects (N = 207) with at least moderate disease severity were given Taclonex® Ointment intermittently on an "as needed" basis for up to 52 weeks. The median use was 15.4 g per week. The effects of Taclonex® Ointment on calcium metabolism were not studied and the effects on the HPA axis were not adequately studied. The following adverse reactions were reported by 1% or more of the subjects: pruritus (7.2%), psoriasis (3.4%), skin atrophy (1.9%), folliculitis (1.4%), burning sensation (1.4%), skin depigmentation (1.4%), ecchymosis (1.0%), erythema (1.0%) and hand dermatitis (1.0%). One case of serious flare-up of psoriasis was reported.
The following adverse reactions associated with the use of Taclonex® Ointment have been identified post-approval: pustular psoriasis and rebound effect.
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.
Postmarketing reports for local adverse reactions to topical corticosteroids may also include: striae, dryness, acneiform eruptions, perioral dermatitis, secondary infection and miliaria.
No Information Provided
Included as part of the "PRECAUTIONS" Section
Hypercalcemia And Hypercalciuria
Hypercalcemia and hypercalciuria have been observed with use of Taclonex® Ointment. If hypercalcemia or hypercalciuria develops, treatment should be discontinued until parameters of calcium metabolism have normalized. In the trials that included assessment of the effects of Taclonex® Ointment on calcium metabolism, such testing was done after 4 weeks of treatment. The effects of Taclonex® Ointment on calcium metabolism following treatment durations of longer than 4 weeks have not been evaluated. [see CLINICAL PHARMACOLOGY]
Effects On Endocrine System
Taclonex® Ointment can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for clinical glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of treatment. Factors that predispose a patient to HPA axis suppression include the use of high-potency corticosteroids, large treatment surface areas, prolonged use, concomitant use of more than one corticosteroid-containing product, use of occlusive dressings, altered skin barrier, liver failure, and young age. Evaluation for HPA axis suppression may be done by using the cosyntropin stimulation test. [see CLINICAL PHARMACOLOGY]
In a trial evaluating the effects of Taclonex® Topical Suspension and Taclonex® Ointment on the HPA axis, 32 adult subjects were treated with Taclonex® Topical Suspension on the scalp and Taclonex® Ointment on the body. Adrenal suppression wasidentified in 5 of 32 subjects (15.6%) after 4 weeks of treatment [see CLINICAL PHARMACOLOGY]. The effects of Taclonex® Ointment on the HPA axis following treatment durations of longer than 4 weeks have not been adequately studied.
If HPA axis suppression is documented, gradually withdraw the drug, reduce the frequency of application, or substitute with a less potent corticosteroid.
Cushing's syndrome and hyperglycemia may also occur due to the systemic effects of topical corticosteroids. These complications are rare and generally occur after prolonged exposure to excessively large doses, especially of high-potency topical corticosteroids.
Pediatric patients may be more susceptible to systemic toxicity due to their higher skin surface to body mass ratios [see Use In Specific Populations, CLINICAL PHARMACOLOGY].
Use of more than one corticosteroid-containing product at the same time may increase the total systemic corticosteroid exposure.
Allergic Contact Dermatitis With Topical Corticosteroids
Allergic contact dermatitis to any component of topical corticosteroids is usually diagnosed by a failure to heal rather than a clinical exacerbation. Clinical diagnosis of allergic contact dermatitis can be confirmed by patch testing.
Allergic Contact Dermatitis With Topical Calcipotriene
Allergic contact dermatitis has been observed with use of topical calcipotriene. Clinical diagnosis of allergic contact dermatitis can be confirmed by patch testing.
If irritation develops, treatment with Taclonex® Ointment should be discontinued and appropriate therapy instituted.
Risk Of Ultraviolet Light Exposure
Patients who apply Taclonex® Ointment to exposed skin should avoid excessive exposure to either natural or artificial sunlight, including tanning booths, sun lamps, etc. Physicians may wish to limit or avoid use of phototherapy in patients who use Taclonex® Ointment.
Patient Counseling Information
See FDA-approved patient labeling (PATIENT INFORMATION).
Inform patients of the following:
- Instruct adult patients (18 years and older) not to use more than 100 g per week.
- Instruct pediatric patients (12 to 17 years) not to use more than 60 g per week.
- Discontinue therapy when control is achieved unless directed otherwise by the physician.
- Avoid use of Taclonex® Ointment on the face, underarms, groin or eyes. If this medicine gets on face or in eyes, wash area right away.
- Do not occlude the treatment area with a bandage or other covering unless directed by the physician.
- Note that local reactions and skin atrophy are more likely to occur with occlusive use, prolonged use or use of higher potency corticosteroids.
- Wash hands after application.
- Instruct patients not to use other products containing calcipotriene or a corticosteroid should not be used with Taclonex® Ointment without first talking to the physician.
- Instruct patients who use Taclonex® Ointment to avoid excessive exposure to either natural or artificial sunlight (including tanning booths, sun lamps, etc.).
Carcinogenesis, Mutagenesis, Impairment Of Fertility
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.
A 104-week oral carcinogenicity study was conducted with calcipotriene in male and female rats at doses of 1, 5 and 15 mcg/kg/day (corresponding to dosages of approximately 6, 30, and 90 mcg/m /day). Beginning week 71, the dosage for high-dose animals of both genders was reduced to 10 mcg/kg/day (corresponding to a dosage of approximately 60 mcg/m2/day). A treatment-related increase in benign Ccell adenomas was observed in the thyroid of females that received 15 mcg/kg/day. A treatment-related increase in benign pheochromocytomas was observed in the adrenal glands of males that received 15 mcg/kg/day. No other statistically significant differences in tumor incidence were observed when compared to control. The relevance of these findings to patients is unknown.
When betamethasone dipropionate was applied topically to CD-1 mice for up to 24 months at dosages approximating 1.3, 4.2 and 8.5 mcg/kg/day in females, and 1.3, 4.2, and 12.9 mcg/kg/day in males (corresponding to dosages of up to approximately 26 mcg/m2/day and 39 mcg/m2/day, in females and males, respectively), no significant changes in tumor incidence were observed when compared to control.
When betamethasone dipropionate was administered via oral gavage to male and female Sprague Dawley rats for up to 24 months at dosages of 20, 60, and 200 mcg/kg/day (corresponding to dosages of approximately 3, 10, and 30 mcg/m /day), no significant changes in tumor incidence were observed when compared to control.
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.
Use In Specific Populations
Pregnancy Category C
There are no adequate and well-controlled studies in pregnant women. Taclonex® Ointment should be used during pregnancy only if the potential benefit to the patient justifies the potential risk to the fetus. Animal reproduction studies have not been conducted with Taclonex® Ointment. Taclonex® Ointment contains calcipotriene that has been shown to be fetotoxic and betamethasone dipropionate that has been shown to be teratogenic in animals when given systemically.
Teratogenicity studies with calcipotriene were performed by the oral route in rats and rabbits. In rabbits, increased maternal and fetal toxicity were noted at a dosage of 12 mcg/kg/day (144 mcg/m2/day); a dosage of 36 mcg/kg/day (432 mcg/m2/day) resulted in a significant increase in the incidence of incomplete ossification of the pubic bones and forelimb phalanges of fetuses. In a rat study, a dosage of 54 mcg/kg/day (324 mcg/m2/day) resulted in a significantly increased incidence of skeletal abnormalities (enlarged fontanelles and extra ribs). The enlarged fontanelles are most likely due to the effect of calcipotriene upon calcium metabolism. The estimated maternal and fetal no-adverse effect levels (NOAEL) in the rat (108 mcg/m2day) and rabbit (48 mcg/m2/day) derived from oral studies are lower than the estimated maximum topical dose of calcipotriene in man (460 mcg/m2/day).
Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels.
Betamethasone dipropionate has been shown to be teratogenic in mice and rabbits when given by the subcutaneous route at dosages of 156 mcg/kg/day (468 mcg/m2/day) and 2.5 mcg/kg/day (30 mcg/m2/day), respectively. Those dose levels are lower than the estimated maximum topical dose in man (about 5950 mcg/m2/day). The abnormalities observed included umbilical hernia, exencephaly and cleft palate.
Two oral peri- and post-natal development studies were conducted with rats:
Pregnant Wistar rats were dosed daily with calcipotriene at exposures of 0, 6, 18 or 54 mcg/kg/day from gestation day 15 through day 20 postpartum. No remarkable effects were observed on any parameter, including survival, behavior, body weight, litter parameters, or the ability to nurse or rear pups.
Betamethasone dipropionate was evaluated for effects when orally administered to pregnant rats from gestation day 6 through day 20 postpartum at dosages of 0, 100, 300, and 1000 mcg/kg/day. Mean maternal body weight was significantly reduced on gestation day 20 in animals dosed at 300 and 1000 mcg/kg/day. The mean duration of gestation was slightly, but statistically significantly, increased at 100, 300, and 1000 mcg/kg/day. The mean percentage of pups that survived to day 4 was reduced in relation to dosage. On lactation day 5, the percentage of pups with a reflex to right themselves when placed on their back was significantly reduced at 1000 mcg/kg/day. No effects on the ability of pups to learn were observed, and the ability of the offspring of treated rats to reproduce was not affected.
Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects.
It is not known whether topically administered calcipotriene or corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk.
Because many drugs are excreted in human milk, caution should be exercised when Taclonex® Ointment is administered to a nursing woman.
Safety and effectiveness of the use of Taclonex® Ointment in pediatric patients under the age of 12 years have not been established.
The safety and effectiveness of Taclonex® Ointment for the treatment of plaque psoriasis have been established in the age group 12 to 17 years. In a prospective, uncontrolled trial, 33 pediatric subjects ages 12-17 years with plaque psoriasis on the body were treated with Taclonex® Ointment for 4 weeks up to a maximum of 55.8 g per week. Subjects were assessed for HPA axis suppression and effects on calcium metabolism. No adverse effects on adrenal suppression were observed. No hypercalcemia was observed but one subject had a possible treatment-related increase in urinary calcium. [see CLINICAL PHARMACOLOGY]
Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of systemic toxicity when treated with topical drugs. They are, therefore, also at greater risk of HPA axis suppression and adrenal insufficiency upon the use of topical corticosteroids. [see WARNINGS AND PRECAUTIONS]
Rare systemic toxicities such as Cushing’s syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients, especially those with prolonged exposure to large doses of high potency topical corticosteroids.
Local adverse reactions including striae have also been reported with use of topical corticosteroids in pediatric patients.
Of the total number of subjects in the clinical studies of Taclonex® Ointment, approximately 14% were 65 years and older and approximately 3% were 75 years and over.
No overall differences in safety or effectiveness of Taclonex® Ointment were observed between these subjects and younger subjects. All other reported clinical experience has not identified any differences in response between elderly and younger patients. However, greater sensitivity of some older individuals cannot be ruled out.
Topically applied Taclonex® Ointment can be absorbed in sufficient amounts to produce systemic effects [see WARNINGS AND PRECAUTIONS].
Mechanism Of Action
Taclonex® Ointment combines the pharmacological effects of calcipotriene hydrate as a synthetic vitamin D3 analogue and betamethasone dipropionate as a synthetic corticosteroid. However, while their pharmacologic and clinical effects are known, the exact mechanisms of their actions in plaque psoriasis are unknown.
In a vasoconstrictor trial in healthy subjects, the skin blanching response of Taclonex® Ointment was consistent with that of a potent corticosteroid when compared with other topical corticosteroids. However, similar blanching scores do not necessarily imply therapeutic equivalence.
Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression
HPA axis suppression was evaluated in four trials (Trial A, B, C and D) following the application of Taclonex® Ointment.
In Trial A, Taclonex® Ointment was applied once daily for 4 weeks to adult subjects (N = 12) with plaque psoriasis to study its effects on the hypothalamic-pituitary-adrenal (HPA) axis. Of eleven subjects tested, none demonstrated adrenal suppression as indicated by a 30-minute post-stimulation cortisol level ≤ 18 mcg/dL.
In Trial B, Taclonex® Ointment was evaluated in adult subjects with plaque psoriasis (N = 19). One subject demonstrated adrenal suppression.
In Trial C, HPA axis suppression was evaluated in adult subjects (N=32) with extensive plaque psoriasis involving at least 30% of the scalp and, in total, 15-30% of the body surface area. Treatment consisted of once daily application of Taclonex® Scalp Topical Suspension on the scalp in combination with Taclonex® Ointment on the body. Adrenal suppression as indicated by a 30-minutes poststimulation cortisol level < 18 mcg/dL was observed in 5 of 32 subjects (15.6%) after 4 weeks of treatment as per the recommended duration of use [see DOSAGE AND ADMINISTRATION].
In Trial D, HPA axis suppression was evaluated in subjects 12 to 17 years (N=32) with plaque psoriasis of the body involving 5-30% of the body surface area. Treatment consisted of once daily application of Taclonex® Ointment to the affected areas for up to 4 weeks. Mean weekly dose was 29.6 g with a range of 8.1-55.8 g/week. Adrenal suppression as indicated by a 30-minute post-stimulation cortisol level ≤18 mcg/dL was observed in none of 32 evaluable subjects after 4 weeks of treatment. [see Use In Specific Populations]
Effects On Calcium Metabolism
In Trial C described above, the effects of once daily application of Taclonex® Ointment on the body in combination with Taclonex® Scalp Topical Suspension on the scalp on calcium metabolism were also examined. Elevated urinary calcium levels outside the normal range were observed in 1 of 35 subjects (2.9%) after 4 weeks of treatment.
In Trial D described above, calcium metabolism was evaluated in a total of 33 subjects aged 12 to 17 years with plaque psoriasis involving 5-30% of the body surface area who underwent once daily application of Taclonex® Ointment for up to 4 weeks. No cases of hypercalcemia and no clinically relevant changes in urinary calcium were reported. However, one subject had a normal urinary calcium:creatinine ratio at baseline (3.75 mmol/g), which increased above the normal range at week 4 (16 mmol/g). There were no relevant changes in albumin-corrected serum calcium or other markers of calcium metabolism for this subject. The clinical significance of this finding is unknown.
In Trial C described above, the systemic effect of Taclonex® Ointment in extensive plaque psoriasis was investigated. In this trial, 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.
Clinical Trials Conducted In Subjects 18 Years And Older With Plaque Psoriasis
In an international, multi-center, double-blind, vehicle- and active-controlled, parallel-group trial, 1603 subjects with mild to very severe plaque psoriasis 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 lesion(s) could just be felt. Table 3 contains the response rates for this trial.

|Absent or very mild
|*Subjects with mild disease at baseline were required to have "Absent" disease to be considered a success.|
In addition to the pivotal trial (N = 490), four randomized, double-blind, vehicle- or active-controlled, parallel-group trials were conducted and provided supportive evidence of efficacy. These trials included a total of 1058 subjects treated with Taclonex® Ointment once daily for up to 4 weeks.
Clinical Trial Conducted In Subjects 12 To 17 Years With Plaque Psoriasis
A prospective, uncontrolled trial (N=33) was conducted in pediatric subjects ages 12 to 17 years with plaque psoriasis involving 5-30% of the body surface area. Approximately 91% of subjects had moderate disease at baseline. Subjects were treated once daily for up to 4 weeks with Taclonex® Ointment. All subjects were evaluated for safety including calcium metabolism (N=33) and 32 subjects were evaluated for HPA axis suppression. [see CLINICAL PHARMACOLOGY]
