5 Warnings and Precautions

5.1 Local Nasal Adverse Reactions

(Additions and/or revisions underlined)

Epistaxis and Nasal Ulceration: In clinical trials of 2 to 26 weeks in duration, epistaxis was observed more frequently in patients treated with ZETONNA than those who received placebo. In the 26-week open-label extension of the perennial allergic rhinitis trial, nasal ulceration was identified in 4 of 824 patients administered ZETONNA (148 mcg) [see Adverse Reactions (6)].

The occurrence of local nasal adverse events was further evaluated in a separate, postmarketing 26-week randomized, open-label, active-controlled nasal and ocular safety trial conducted in patients with perennial allergic rhinitis. In this study epistaxis was observed in 6% of patients treated with ZETONNA and nasal ulceration was identified in 3 of 367 patients administered ZETONNA. [see Adverse Reactions (6)].

Nasal Septal Perforation: Nasal septal perforation has been reported in patients following the nasal application of ZETONNA. Three short-term placebo-controlled trials (2 weeks) and one long-term (26 weeks with placebo control and 26 weeks open-label extension without placebo control) trial were conducted in patients with seasonal and perennial allergic rhinitis. Nasal septal perforations were reported in 2 patients out of 2335 patients treated with ZETONNA compared with none of 892 patients treated with placebo. No nasal septal perforations were reported in 367 patients treated with ZETONNA in a postmarketing 26-week, open-label, active- controlled trial in patients with perennial allergic rhinitis [see Adverse Reactions (6)].

Before starting ZETONNA conduct a nasal examination to ensure that patients are free of nasal disease other than allergic rhinitis. Periodically monitor patients with nasal examinations during treatment for adverse effects in the nasal cavity. If an adverse reaction (e.g. erosion, ulceration, perforation) is noted, discontinue ZETONNA. Avoid spraying ZETONNA directly onto the nasal septum.

Candida Infection: Localized infections of the nose or pharynx with Candida albicans has occurred from the use of ciclesonide. If such an infection occurs with ZETONNA, treat it with appropriate local therapy and discontinue ZETONNA.

5.2 Glaucoma and Cataracts

(Additions and/or revisions underlined)

Nasal and inhaled corticosteroids, including ZETONNA, can result in the development of glaucoma and cataracts. Therefore, close monitoring is warranted in patients with a change in vision or with a history of increased intraocular pressure, glaucoma, or cataracts.

5.3 Hypersensitivity Reactions

(Additions and/or revisions underlined)

ZETONNA is contraindicated in patients with a known hypersensitivity to ciclesonide or any of the ingredients of ZETONNA. Hypersensitivity reactions including angioedema, with swelling of the lips, tongue and pharynx, have occurred after nasal administration of ZETONNA. Discontinue ZETONNA if such reactions occur.

5.4 Immunosuppression and Risk of Infections

(Additions and/or revisions underlined)

Patients who are using drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chickenpox and measles, for example, can have a more serious or even fatal course in susceptible children or adults using corticosteroids. In children or adults who have not had these diseases or been properly immunized, particular care should be taken to avoid exposure. How the dose, route, and duration of corticosteroid administration affect the risk of developing a disseminated infection is not known. The safety and effectiveness of ZETONNA have not been established in pediatric patients less than 12 years of age and ZETONNA is not indicated for use in this population. The contribution of the underlying disease or prior corticosteroid treatment to the risk is also not known. If a patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If a patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated (see the respective Prescribing Information for VZIG and IG). If chickenpox develops, treatment with antiviral agents may be considered.

5.5 Hypercorticism and Adrenal Suppression

(Additions and/or revisions underlined)

Hypercorticism and adrenal suppression may occur when nasal corticosteroids, including ZETONNA, are used at higher-than-recommended dosages [see Dosage and Administration (2)] or thepatients at risk for such effects.

5.6 Effect on Growth

(Additions and/or revisions underlined)

Corticosteroids, including ZETONNA, may cause a reduction in growth velocity when administered to pediatric patients. The safety and effectiveness of ZETONNA have not been established in pediatric patients less than 12 years of age and ZETONNA is not indicated for use in this population. Monitor the growth routinely (e.g., via stadiometry) in pediatric patients receiving ZETONNA [see Pediatric Use (8.4)].

6 Adverse Reactions

6.1 Clinical Trials Experience

(Additions and/or revisions underlined)

The safety data described below for adult and pediatric patients 12 years of age and older are based on 4 clinical trials evaluating doses of ciclesonide from 74 to 282 mcg. Three of the clinical trials were 2 to 6 weeks in duration and one trial was 26 weeks in duration with an additional 26-week open-label extension. Data from the first 6 weeks of the 26-week trial were pooled with data from the three 2-week trials. Short-term data (2 to 6 weeks) included

Table 1 displays reactions that occurred with an incidence of at least 2.0% and more frequently with ZETONNA 74 mcg than with placebo in seasonal or perennial allergic rhinitis clinical trials of 2 to 6 weeks duration.

In one 26-week double-blind, placebo-controlled safety trial that included 1110 adult and pediatric patients (12 to 17 years of age) with perennial allergic rhinitis, additional adverse reactions, with an incidence of at least 2%, that occurred more frequently with ZETONNA than with placebo were upper respiratory tract infection, urinary tract infection, oropharyngeal pain, nasal mucosal/septum disorders, viral upper respiratory tract infection, cough, influenza, bronchitis, streptococcal pharyngitis, muscle strain, and nausea. Nasal discomfort (5.7%) and epistaxis (11.4%) were also more frequent in the 26-week safety trial compared to clinical trials 2 to 6 weeks in duration. Nasal mucosal/septum disorders and cough demonstrated a dose response.

Nasal and ocular safety was evaluated in one 26-week, postmarketing, randomized, open-label, active-controlled trial, in adult and pediatric patients 12-74 years of age with a history of perennial allergic rhinitis…

8.4 Pediatric Use

(Additions and/or revisions underlined)

The safety and effectiveness for seasonal and perennial allergic rhinitis in pediatric patients 12 years of age and older have been established. Use of ZETONNA for this indication is supported by evidence from placebo-controlled, double-blind trials in patients 12 years and older with allergic rhinitis [see Clinical Studies (14)].

The safety and effectiveness of ZETONNA have not been established in pediatric patients younger than 12 years of age.

Effectiveness was not demonstrated for ZETONNA in pediatric patients 6 through 11 years of age. These patients were evaluated in 2 randomized, double blind, parallel placebo-controlled clinical trials in 1693 pediatric patients with allergic rhinitis. Of the 2 trials, 1 was 2 weeks in duration and evaluated the efficacy of 2 doses of ZETONNA (37 mcg and 74 mcg once daily) in 847 patients with seasonal allergic rhinitis. The second clinical trial was 12 weeks in duration and evaluated the efficacy of 2 doses of ZETONNA (37 mcg and 74 mcg once daily) in 846 patients with perennial allergic rhinitis. The trials were similar in design to the trials conducted in pediatric patients 12 years and older and adults. The primary efficacy endpoint was the difference from placebo in the change from baseline of the average morning and evening reflective total nasal symptom scores (rTNSS) averaged over 2 weeks of treatment in the seasonal allergic rhinitis trial and over the first 6 weeks of treatment in the perennial allergic rhinitis trial. In the 2-week trial in patients with seasonal allergic rhinitis, treatment with ZETONNA at either dose failed to demonstrate efficacy. In the 12-week trial in patients with perennial allergic rhinitis, both ZETONNA 37 mcg and 74 mcg once daily demonstrated significant improvement in rTNSS compared to placebo with treatment differences of 0.59 (95% CI: 0.23, 0.95) and 0.47 (95% CI: 0.11, 0.83), respectively.

The effect of ZETONNA on the HPA axis was evaluated in one placebo-controlled clinical study of 6 weeks in duration in children 6 to11 years of age with perennial allergic rhinitis [see Clinical Pharmacology (12.2)].

Studies in pediatric patients under 6 years of age have not been conducted.

Effect on Growth

Controlled clinical trials have shown that nasal corticosteroids may cause a reduction in growth velocity in pediatric patients. This effect has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA)-axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA-axis function. The long-term effects of this reduction in growth velocity associated with nasal corticosteroids, including the impact on final adult height, are unknown. The potential for “catch-up” growth following discontinuation of treatment with nasal corticosteroids has not been adequately studied. The growth of pediatric patients receiving nasal corticosteroids, including ZETONNA, should be monitored routinely (e.g., via stadiometry). A 52-week, multi-center, double-blind, randomized, placebo-controlled parallel- group trial was conducted to assess the effect of orally inhaled ciclesonide (ALVESCO® Inhalation Aerosol) on growth rate in 609 pediatric patients with mild persistent asthma, aged 5 to 8.5 years. Treatment groups included orally inhaled ciclesonide 40 mcg or 160 mcg or placebo given once daily. Growth was measured by stadiometer height during the baseline, treatment and follow-up periods. The primary comparison was the difference in growth rates between ciclesonide 40 and 160 mcg and placebo groups. Conclusions cannot be drawn from this trial because compliance could not be assured. Ciclesonide blood levels were also not measured during the one-year treatment period. There was no difference in efficacy measures between the placebo and the orally inhaled ciclesonide (ALVESCO® Inhalation Aerosol) groups.

The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the availability of safe and effective noncorticosteroid treatment alternatives. To minimize the systemic effects of nasal corticosteroids, each patient should be titrated to the lowest dose that effectively controls his/her symptoms…

17 PATIENT COUNSELING INFORMATION

(Additions and/or revisions underlined)

Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use).

 

Local Nasal Adverse Reactions

Inform patients that treatment with ZETONNA may lead to adverse reactions, which include nasal septal perforation, epistaxis, and nasal ulceration. In addition, ciclesonide is associated with candidal infection, and nasal corticosteroids are associated with impaired wound healing. Do not spray ZETONNA directly onto the nasal septum. Patients who have experienced recent nasal septal perforation, nasal erosion, nasal ulcers, nasal surgery, or nasal trauma should not use ZETONNA until healing has occurred [see Warnings and Precautions (5.1)].

Immunosuppression and Risk of Infections

Warn patients who are on immunosuppressive doses of corticosteroids to avoid exposure to chickenpox or measles, and if exposed, to consult their physician without delay. Inform patients of potential worsening of existing tuberculosis, fungal, bacterial, viral or parasitic infections, or ocular herpes simplex [see Warnings and Precautions (5.4)]…
