• Psoriasis

Calcipotriene Ointment, 0.005%, is indicated for the treatment of plaque psoriasis in adults. The safety and effectiveness of topical calcipotriene in dermatoses other than psoriasis have not been established.

General

Use of Calcipotriene Ointment may cause irritation of lesions and surrounding uninvolved skin. If irritation develops, Calcipotriene Ointment should be discontinued.

For external use only. Keep out of the reach of children. Always wash hands thoroughly after use.

Transient, rapidly reversible elevation of serum calcium has occurred with use of Calcipotriene Ointment. If elevation in serum calcium outside the normal range should occur, discontinue treatment until normal calcium levels are restored.

Information for Patients

Patients using Calcipotriene Ointment should receive the following information and instructions:

1. This medication is to be used as directed by the physician. It is for external use only. Avoid contact with the face or eyes. As with any topical medication, patients should wash hands after application.

2. This medication should not be used for any disorder other than that for which it was prescribed.

3. Patients should report to their physician any signs of local adverse reactions.

4. Patients that apply Calcipotriene Ointment to exposed portions of the body should 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 μg/kg/day (corresponding to 9, 30 and 90 μg/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 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. Patients that apply Calcipotriene Ointment to exposed portions of the body should avoid excessive exposure to either natural or artificial sunlight (including tanning booths, sun lamps, etc.). Physicians may wish to avoid use of phototherapy in patients that use Calcipotriene Ointment.

Calcipotriene did not elicit any mutagenic effects in an Ames mutagenicity assay, a mouse lymphoma TK locus assay, a human lymphocyte chromosome aberration assay, or in a micronucleus assay conducted in mice.

Studies in rats at doses up to 54 μg/kg/day (324 μg/m2/day) of calcipotriene indicated no impairment of fertility or general reproductive performance.

Pregnancy

Teratogenic Effects: Pregnancy Category C

Studies of teratogenicity were done by the oral route where bioavailability is expected to be approximately 40-60% of the administered dose. In rabbits, increased maternal and fetal toxicity were noted at a dosage of 12 μg/kg/day (132 μg/m2/day); a dosage of 36 μg/kg/day (396 μg/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 μg/kg/day (318 μg/m2/day) resulted in a significantly increased incidence of skeletal abnormalities (enlarged fontanelles and extra ribs). The enlarged fontanelles are most likely due to calcipotriene’s effect upon calcium metabolism. The estimated maternal and fetal no-effect exposure levels in the rat (43.2 μg/m2/day) and rabbit (17.6 μg/m2/day) studies are approximately equal to the expected human systemic exposure level (18.5 μg/m2/day) from dermal application. There are no adequate and well-controlled studies in pregnant women. Therefore, Calcipotriene Ointment should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether calcipotriene is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Calcipotriene Ointment, 0.005% is administered to a nursing woman.

Pediatric Use

Safety and effectiveness of Calcipotriene Ointment in pediatric patients have not been established. Because of a higher ratio of skin surface area to body mass, pediatric patients are at greater risk than adults of systemic adverse effects when they are treated with topical medication.

Geriatric Use

Of the total number of patients in clinical studies of Calcipotriene Ointment, approximately 12% were 65 or older, while approximately 4% were 75 and over. The results of an analysis of severity of skin-related adverse events showed a statistically significant difference for subjects over 65 years (more severe) compared to those under 65 years (less severe).

Clinical Trials Experience

In controlled clinical trials, the most frequent adverse reactions reported for Calcipotriene Ointment were burning, itching and skin irritation, which occurred in approximately 10-15% of patients. Erythema, dry skin, peeling, rash, dermatitis, worsening of psoriasis including development of facial/scalp psoriasis were reported in 1 to 10% of patients. Other experiences reported in less than 1% of patients included skin atrophy, hyperpigmentation, hypercalcemia, and folliculitis. Once daily dosing has not been shown to be superior in safety to twice daily dosing.

Postmarketing Experience

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.

The following adverse reactions associated with the use of Calcipotriene Ointment have been identified post-approval: contact dermatitis, including allergic contact dermatitis.

Apply a thin layer of Calcipotriene Ointment once or twice daily and rub in gently and completely.
