  • 5 WARNINGS AND PRECAUTIONS

    5.1 Effects on Calcium Metabolism

    In controlled clinical trials with Calcitriol Ointment, 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 increases in calcium and albumin-adjusted calcium levels were less than 10% above the upper limit of normal.

    If aberrations in parameters of calcium metabolism occur, treatment should be discontinued until these parameters have normalized. The effects of Calcitriol Ointment on calcium metabolism following treatment durations greater than 52 weeks have not been evaluated. Increase absorption may occur with occlusive use.

    5.2 Ultraviolet Light Exposure

    Animal data suggest that the vehicle of calcitriol Ointment may enhance the ability of ultraviolent radiation (UVR) to induce skin tumors [see Carcinogenesis, Mutagenesis, Impairment of Fertility (13.1)] Subjects who apply Calcitriol Ointment to exposed skin should avoid excessive exposure to the treated areas to either natural or artificial sunlight, including tanning booths and sun lamps. Physicians may wish to limit or avoid use of phototherapy in patients who use Calcitriol Ointment.

    5.3 Unevaluated Uses

    The safety and effectiveness of Calcitriol Ointment in patients with known or suspected disorders of calcium metabolism have not been evaluated. The safety and effectiveness of Calcitriol Ointment in patients with erythrodermic, exfoliative, or pustular psoriasis have not been evaluated.

  • 6 ADVERSE REACTIONS

    Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rate observed in practice.

    6.1 Clinical Studies Experience

    Calcitriol Ointment was studied in two vehicle-controlled studies (419 subjects), and in one open label study (324 subjects). The table below describes exposure to Calcitriol Ointment in 743 subjects, including 239 exposed for 6 months and 116 exposed for one year.

    Four hundred and nineteen subjects were treated with Calcitriol 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.

    Image 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 [see WARNINGS AND PRECAUTIONS (5.1)]

    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 Calcitriol Ointment were lab test abnormality (8%), urine abnormality (4%), psoriasis (4%), hyperciuria (3%), and pruritus (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, pruritus, skin burning sensation, and skin discomfort. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a cause relationship to drug exposure.

  • 7 DRUG INTERACTIONS

    Calcitriol Ointment should be used with caution in patients receiving medications known to increase the serum calcium level, such as thiazide diuretics. Caution should also be exercised in patients receiving calcium supplements or high doses of vitamin D [see WARNINGS AND PRECAUTIONS (5.1)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Teratogenic Effects: Pregnancy Category C.

    Calcitriol Ointment contains calcitriol which has been shown to be fetotoxic. There are no adequate and well-controlled studies for Calcitriol Ointment in pregnant women. Calcitriol Ointment should be used during pregnancy only if the potential benefit to the patient justifies the potential risk to the fetus.

    Teratogenicity studies with calcitriol were performed in which rats were treated orally at dosages of 0.9 mcg/kg/day (5.4 mcg/m/day) and in which rabbits received topical application of calcitriol ointment (3 ppm) to 6.4% of the body surface area. No effect reproductive or fetal parameters were observed in rats. In rabbits, topically applied calcitriol induced a significantly elevated mean post-implantation loss and increase incidence of minor skeletal abnormalities due to retarded ossification of the pubic bones. A slight increased incidence of skeletal variation (extra 13th rib, reduced ossification of epiphyses) was also observed. These effects may have been secondary to maternal toxicity. Based on the recommended human dose and instructions for use, it is not possible to calculate human dose equivalents for animal exposures in these studies.

    8.3 Nursing Mothers

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

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5 Geriatric Use

    Clinical studies of Calcitriol Ointment did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported experience has not identified differences in responses between the elderly and younger patients.

  • 12 CLINICAL PHARMACOLOGY

    The contribution to efficacy of individual components of the vehicle has not been established.

    12.1 Mechanism of Action

    The mechanism of action of calcitriol in the treatment of psoriasis has not been established.

    12.3 Pharmacokinetics

    The systemic exposure of calcitriol was assessed in subjects with chronic, plaque psoriasis. In the pivotal pharmacokinetic/pharmacodynamic study, calcitriol ointment 3 mcg/g, was applied twice daily for 21 days (for a total dose of 30 g/day) to 35% of the body surface area (psoriatic + surrounding healthy skin) of subjects with at least 25% of body surface area involvement. At Day 21, the geometric mean plasma concentration values of Cmax increased by approximately 36% over baseline and the geometric mean value of AUC(0-12hr) increased by 44%. There was no correlation between the elevated calcitriol levels and the pharmacodynamic parameters or serum albumin adjusted calcium, serum phosphorus, urinary calcium and urinary phosphorus.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    When calcitriol was applied topically to mice for up to 24 months, no significant changes in tumor incidence were observed. Concentrations of calcitriol in ointment base of 0 (vehicle control), 0.3, 0.6 and 1.0 ppm were evaluated.

    A two-year carcinogenicity study was conducted in which calcitriol wasorally administered to rats at dosages of approximately0.005, 0.03, and 0.1 mcg/kg/day (0.03, 0.18, and 0.6 mcg/m2/day, respectively). The incidence of benign pheochromocytomas was significantly increased in female rats. No other significant differences in tumor incidence data were observed.

    In a study in which albino hairless mice were exposed to both ultra-violet radiation (UVR) and topically applied calcitriol ointment, a reduction in the time required for UVR to induce the formation of skin tumors was observed in all groups that received the ointment base, including the vehicle-treated control group, relative to animals that received no ointment but which were exposed to UVR. The time required for UVR to induce the formation of skin tumors did not differ between animals that received plain vehicle and those that recieved vehicle that contained calcitriol. Concentrations of calcitriol in ointment base of 0 (vehicle control), 0.3, 0.6, and 1.0 ppm were evaluated. These data suggest that the vehicle of Calcitriol Ointment may enhance the ability of UVR to induce skin tumors.

    Calcitriol did not elicit genotoxic effects in the mouse lymphoma TK locus assay.

    Studies in which male and female rats received oral doses of calcitriol of up to 0.6 mcg/kg/day (3.6 mcg/m2/day) indicated no impairment of fertility or general reproductive performances.

    Based upon the recommended human dose and instructions for use, it is not possible to calculate human dose equivalents for animal exposure in these studies.

  • 14 CLINICAL STUDIES

    In two, multicenter, double-blind, vehicle-controlled studies, a total of 839 subjects with psoriasis rated “mild” or “moderate” using an investigator global assessment scale were tested twice daily for 8 weeks. Subjects were randomized in a 1:1 ratio to receive either Calcitriol Ointment or vehicle ointment. The mean age of subjects was 48 years and 66% were male; most subjects were rated “moderate” at baseline.

    Success was defined as "Clear or Minimal" (up to light red or pink coloration, surface dryness with some white coloration, and slight elevation above normal skin) with at least 2-grade change from baseline. The success rates are displayed in the table.
