Warnings and precautions

Local Nasal Adverse Reactions: epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing. Monitor patients periodically for signs of adverse effects on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma. ( 5.1 ) Glaucoma and Cataracts may occur with long-term use. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use XHANCE long-term.

( 5.2 ) Hypersensitivity reactions (e.g., anaphylaxis, angioedema, urticaria, contact dermatitis, rash, hypotension, and bronchospasm) have been reported after administration of fluticasone propionate. Discontinue XHANCE if such reactions occur. ( 5.3 ) Immunosuppression and Risk of Infection: potential increased susceptibility to or worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infection; ocular herpes simplex).

Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients.

8.1Pregnancy Risk Summary

Available data from published literature on the use of inhaled or nasal fluticasone propionate in pregnant women have not reported a clear association with adverse developmental outcomes. In animals, teratogenicity characteristic of corticosteroids, decreased fetal body weight, and/or skeletal variations in rats, mice, and rabbits were observed with subcutaneously administered maternal toxic doses of fluticasone propionate less than the maximum recommended human daily inhaled dose (MRHDID) on a mcg/m 2 basis.

However, fluticasone propionate administered via inhalation to rats decreased fetal body weight, but did not induce teratogenicity at a maternal toxic dose less than the MRHDID on a mcg/m 2 basis ( see Data ). Experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroids than humans. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and miscarriages in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In embryofetal development studies with pregnant rats and mice dosed by the subcutaneous route throughout the period of organogenesis, fluticasone propionate was teratogenic in both species.

Omphalocele, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, at a dose approximately equivalent to the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 100 mcg/kg/day). The rat no observed adverse effect level (NOAEL) was observed at approximately 0.4 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 30 mcg/kg/day).

Cleft palate and fetal skeletal variations were observed in mouse fetuses at a dose approximately 0.3 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 45 mcg/kg/day). The mouse NOAEL was observed with a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 15 mcg/kg/day). In an embryofetal development study with pregnant rats dosed by the inhalation route throughout the period of organogenesis, fluticasone propionate produced decreased fetal body weights and skeletal variations, in the presence of maternal toxicity, at a dose approximately 0.34 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 25.7 mcg/kg/day); however, there was no evidence of teratogenicity.

The NOAEL was observed with a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 5.5 mcg/kg/day). In an embryofetal development study in pregnant rabbits that were dosed by the subcutaneous route throughout organogenesis, fluticasone propionate produced reductions of fetal body weights, in the presence of maternal toxicity, at doses approximately 0.02 times the MRHDID and higher (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.57 mcg/kg/day).

Teratogenicity was evident based upon a finding of cleft palate for 1 fetus at a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 4 mcg/kg/day). The NOAEL was observed in rabbit fetuses with a dose approximately 0.002 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.08 mcg/kg/day). Fluticasone propionate crossed the placenta following subcutaneous administration to mice and rats and oral administration to rabbits.

In a pre- and post-natal development study in pregnant rats dosed from late gestation through delivery and lactation (Gestation Day 17 to Postpartum Day 22), fluticasone propionate was not associated with decreases in pup body weight, and had no effects on developmental landmarks, learning, memory, reflexes, or fertility at doses up to 0.7 times the MRHDID (on a mcg/m 2 basis with maternal subcutaneous doses up to 50 mcg/kg/day).

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Chronic Rhinosinusitis with Nasal Polyps The safety data described below are based on two placebo-controlled clinical trials evaluating doses of a fluticasone propionate nasal spray with an exhalation delivery system from 93 mcg twice daily to 372 mcg twice daily.

Both trials were 16-weeks in duration with an additional 8-week open-label extension. The trials included a total of 643 adult patients with bilateral nasal polyps and associated moderate or severe nasal congestion of which 161 received 93 mcg twice daily, 160 received 186 mcg twice daily, 161 received 372 mcg twice daily and 161 received placebo. The overall pooled safety data included 296 (46.0%) Female, 347 (54.0%) Male, 584 (90.8%) White, 39 (6.1%) Black, 9 (1.4%) Asian, and 11 (1.7%) patients classified as Other.

Of these patients, 45 (7%) were 65 years of age or older. Table 1 displays adverse reactions with an incidence of ≥ 3% in the XHANCE 186 mcg and 372 mcg twice daily patients, and more common than placebo. Table 1.

There were no clinically relevant differences in the incidence of adverse reactions based on gender. Clinical trials did not include sufficient numbers of non-Caucasian patients or patients aged 65 years and older to determine whether they respond differently from Caucasian or younger patients, respectively. Chronic Rhinosinusitis without Nasal Polyps The safety of XHANCE was based on a pooled safety population that reflect the exposure of XHANCE in 367 adults with chronic rhinosinusitis with (CRSwNP) or without nasal polyps (CRSsNP) exposed for 24 weeks duration.

XHANCE was studied in two randomized, placebo-controlled, multicenter trials (Trial 3 and Trial 4). Patients received either XHANCE 186 mcg (1 spray per nostril) twice daily, XHANCE 372 mcg (2 sprays per nostril) twice daily, or placebo delivered with an exhalation delivery system. The pooled safety population had a mean age of 49 years [age range: 18 to 87], and were 55% male, 94% White, 96% non-Hispanic or Latino, 4% Black or African American, and 2% Asian.

In these trials, 1.6% of patients treated with XHANCE 186 mcg (1 spray per nostril) twice daily and 1.6% of patients treated with 372 mcg (2 sprays per nostril) twice daily discontinued treatment due to adverse reactions compared to 2.7% of patients treated with placebo. The most common adverse reactions that occurred at a rate of ≥ 3% in patients treated with XHANCE and at a higher rate in at least one treatment group than placebo from the pooled safety population (Trials 3 and 4) are shown in Table 2.

6.2Postmarketing Experience

The following adverse reactions have been identified during postapproval use of XHANCE. 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. Eye disorders: central serous chorioretinopathy Respiratory, thoracic, and mediastinal disorders: dysphonia, nasal discomfort, and nasal dryness Skin and subcutaneous tissue disorders: pruritus, rash
