Side Effects & Drug Interactions


Clinical Trials Experience

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

SORILUX (calcipotriene foam) Foam was studied in three-vehicle controlled trials. Seven hundred and thirty one subjects with plaque psoriasis, including 473 exposed to SORILUX (calcipotriene foam) Foam were treated twice daily for 8 weeks.

Adverse events reported in greater than 1% of subjects and in a higher rate in subjects treated with SORILUX (calcipotriene foam) Foam compared to vehicle were limited to erythema.


No drug interaction studies were conducted with SORILUX (calcipotriene foam) Foam.

Warnings & Precautions


Included as part of the PRECAUTIONS section.



The propellant in SORILUX (calcipotriene foam) is flammable. Instruct the patient to avoid fire, flame, and/or smoking during and immediately following application.

Effects on Calcium Metabolism

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

Ultraviolet Light Exposure

Instruct the patient to avoid excessive exposure of 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 SORILUX (calcipotriene foam) Foam. [See Nonclinical Toxicology]

Unevaluated Uses

SORILUX (calcipotriene foam) Foam has not been evaluated in patients with erythrodermic, exfoliative, or pustular psoriasis.

Patient Counseling Information

[See FDA-Approved Patient Labeling]

The patient should be instructed as follows:

  • Do not place SORILUX (calcipotriene foam) Foam in the refrigerator or freezer.
  • Avoid excessive exposure of the treated areas to either natural or artificial sunlight, including tanning beds and sun lamps.
  • If SORILUX (calcipotriene foam) Foam gets in or near their eyes, to rinse thoroughly with water.
  • Talk to their doctor if their skin does not improve after treatment with SORILUX (calcipotriene foam) Foam for 8 weeks.
  • Wash their hands after applying SORILUX (calcipotriene foam) Foam unless their hands are the affected site
  • Avoid fire, flame, or smoking during and immediately following application since SORILUX (calcipotriene foam) Foam is flammable.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Calcipotriene topically administered to mice for up to 24 months at dose levels of 3, 10, or 30 mcg/kg/day (corresponding to 9, 30, or 90 mcg/m2/day) showed no significant changes in tumor incidence when compared to controls. 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. [See WARNINGS AND PRECAUTIONS]

The genotoxic potential of calcipotriene was evaluated in an Ames assay, a mouse lymphoma TK locus assay, a human lymphocyte chromosome aberration assay, and a mouse micronucleus assay. All assay results were negative.

Studies in rats at doses up to 54 mcg/kg/day (318 mcg /m2/day) of calcipotriene indicated no impairment of fertility or general reproductive performance.

Use In Specific Populations


Teratogenic Effects, Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Therefore, SORILUX (calcipotriene foam) Foam should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Studies of teratogenicity were done by the oral route where bioavailability is expected to be approximately 40-60% of the administered dose. Increased rabbit maternal and fetal toxicity was noted at 12 mcg/kg/day (132 mcg/m2/day). Rabbits administered 36 mcg/kg/day (396 mcg/m2/day) resulted in fetuses with a significant increase in the incidences of incomplete ossification of pubic bones and forelimb phalanges. In a rat study, doses of 54 mcg/kg/day (318 mcg/m2/day) resulted in a significantly higher incidence of skeletal abnormalities consisting primarily of enlarged fontanelles and extra ribs. The enlarged fontanelles are most likely due to calcipotriene's effect upon calcium metabolism. The maternal and fetal no-effect exposures in the rat (43.2 mcg/m2/day) and rabbit (17.6 mcg/m2/day) studies are approximately equal to the expected human systemic exposure level (18.5 mcg/m2/day) from dermal application.

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 SORILUX (calcipotriene foam) Foam is administered to a nursing woman.

Pediatric Use

Safety and effectiveness of SORILUX (calcipotriene foam) Foam in pediatric patients less than 18 years of age have not been established.

Geriatric Use

Clinical studies of SORILUX (calcipotriene foam) Foam did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

Overdosage & Contraindications


Topically applied calcipotriene can be absorbed in sufficient amounts to produce systemic effects. Elevated serum calcium has been observed with use of topical calcipotriene. [See WARNINGS AND PRECAUTIONS]


SORILUX (calcipotriene foam) Foam should not be used by patients with known hypercalcemia.

Clinical Pharmacology


Mechanism of Action

Calcipotriene is a synthetic vitamin D3 analog that has a similar receptor binding affinity as natural vitamin D3. However, the exact mechanism of action contributing to the clinical efficacy in the treatment of psoriasis is unknown.


The pharmacodynamics of SORILUX (calcipotriene foam) Foam are unknown.


The systemic absorption of calcipotriene in psoriatic subjects was evaluated at steady state following application of SORILUX Foam or calcipotriene ointment. In the SORILUX Foam treatment group, 15 out of 16 subjects showed calcipotriene plasma concentrations below the limit of quantitation (10 pg/mL), while in the calcipotriene ointment treated group, 5 out of 16 subjects had measurable calcipotriene plasma concentrations at various time points. All measurable plasma calcipotriene concentrations were below 25 pg/mL.

The systemic disposition of calcipotriene is expected to be similar to that of the naturally occurring vitamin D. Absorbed calcipotriene is known to be converted to inactive metabolites within 24 hours of application and the metabolism occurs via a similar pathway to the natural hormone.

Clinical Studies

In two multi-center, randomized, double-blind, vehicle-controlled clinical studies a total of 659 subjects with psoriasis were randomized 2:1 to SORILUX (calcipotriene foam) Foam or vehicle; subjects applied the assigned medication twice daily for 8 weeks. Baseline disease severity was graded using a 5-point Investigator Static Global Assessment scale (ISGA), on which subjects scored either "mild" or "moderate" as shown in Table 1.

Table 1: Investigator Static Global Assessment (ISGA) Scale

Disease Severity Grade Definition
clear 0 No evidence of scaling, erythema, or plaque thickness
almost clear 1 Occasional fine scale, faint erythema, and barely perceptible plaque thickness
mild 2 Fine scale with light coloration and mild plaque elevation
moderate 3 Coarse scale with moderate red coloration and moderate plaque thickness
severe 4 Thick tenacious scale with deep coloration and severe plaque thickness

Efficacy evaluation was carried out at Week 8 with treatment success being defined as a score of "clear" (grade 0) or "almost clear" (grade 1) and at least 2 grade improvement from the baseline score. Approximately 30% of enrolled subjects were graded as "mild" on the ISGA scale. The study population ranged in age from 12 to 89 years with 10 subjects less than 18 years of age at baseline. The subjects were 54% male and 88% Caucasian. Table 2 presents the efficacy results for each study.

In one study, subjects graded as "mild" at baseline showed a greater response to vehicle than SORILUX (calcipotriene foam) Foam.
