Ciclesonide

Pregnancy

8.1 Pregnancy Risk Summary There are no data on ONMARIS nasal spray use in pregnant women to assess a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes . There is low systemic exposure following OMNARIS nasal spray administration at the recommended dose [see Clinical Pharmacology ( 12.3 )] . In animal reproduction studies, ciclesonide, administered by the oral route to pregnant rats, during the period of organogenesis, did not cause any evidence of fetal harm at doses up 45 times the maximum recommended human daily intranasal dose (MRHDID) of 200 mcg/day. Teratogenicity, characteristic of corticosteroids, decreased body weight and/or skeletal variations were observed in rabbit fetuses following administration of ciclesonide to pregnant rabbits by the subcutaneous route during the period of organogenesis at doses 0.5 times the MRHDID and higher on a mcg/m 2 basis (see Data ). No evidence of fetal harm was observed in rabbits at doses 0.1 times the MRHDID. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the United States general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal development study in pregnant rats dosed by the oral route during the period of organogenesis from gestation days 6 to 15, ciclesonide did not cause any evidence of fetal harm at doses up to 45 times the MRHDID in adults (on a mcg/m 2 basis with maternal oral dose up to 900 mcg/kg/day). Maternal toxicity, as evidenced by decreased body weight gain, was observed at 45 times the MRHDID in adults (on a mcg/m 2 basis at a maternal dose of 900 mcg/kg/day); however, no adverse effects were observed at doses 15 times the MRHDID and lower (on a mcg/m 2 basis with maternal oral doses of 300 mcg/kg/day and lower). In two embryo-fetal development studies in pregnant rabbits dosed by the subcutaneous route during the period of organogenesis from gestation days 6 to 18, ciclesonide caused acampsia (flexures of legs) in fetuses at doses 0.5 times the MRHDID and higher (on a mcg/m 2 basis with maternal oral doses of 5 mcg/kg/day and higher), decreased body weight, cleft palate, enlarged fontanelle, parchment-like skin, and incomplete ossification of bones in fetuses at doses 2 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 25 µg/kg/day) and embryo-fetal death at doses 10 times the MRHDID and higher (on a mcg/m 2 basis at maternal subcutaneous doses of 100 mcg/kg/day and higher). No evidence of fetal harm was observed at a dose 0.1 times the MRHDID in adults (on a mcg/m 2 basis at a maternal subcutaneous dose of 1 mcg/kg/day). Maternal toxicity was observed at doses 10 times the MRHDID in adults (on a mcg/m 2 basis with maternal subcutaneous doses of 100 mcg/kg/day and lower); however, no evidence of toxicity was observed at doses 2 times the MRHDID and lower (on a mcg/m 2 basis with maternal subcutaneous doses of 25 mcg/kg/day and lower). In a prenatal and postnatal development study in pregnant rats dosed by the oral route from gestation day 6 to lactation day 20, ciclesonide produced no adverse developmental effects on offspring at doses up to approximately 45 times the MRHDID (on mcg/m 2 bases at maternal oral doses up to 900 mcg/kg/day).

It is not known whether nasal spray administration of ciclesonide at the recommended dose could result in sufficient systemic absorption to produce detectable quantities in human milk [see Clinical Pharmacology ( 12.3 )] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for OMNARIS Nasal Spray, and any potential adverse effects on the breastfed child from OMNARIS Nasal Spray, or from the underlying maternal condition. Clinical Considerations The pharmacokinetics of intranasally administered ciclesonide have not been assessed in patient subpopulations because the resulting blood levels of ciclesonide and des-ciclesonide are insufficient for pharmacokinetic calculations [ see Clinical Pharmacology ( 12.3 )] . The molecular weight of the prodrug ciclesonide (approximately 541 g/mol) is small enough to be excreted into breast milk; however, its high plasma protein binding affinity and very short half-life suggest that minimal amounts will be present within the milk. Conversely, the half-life of the active metabolite des-ciclesonide (approximately 471 g/mol) suggests that exposure to the nursing infant will be greater than that of the prodrug ciclesonide. Although ciclesonide and des-ciclesonide have negligible oral bioavailability (both less than 1% for each) due to low gastrointestinal absorption and high first-pass metabolism, the relative anti‑inflammatory activity of des-ciclesonide is 12-times greater than that of dexamethasone. The effects of this exposure on a nursing infant are unknown, however, like all corticosteroids, suppression of the HPA function is a potential complication. Data Human Data At recommended doses, the intranasal administration of ciclesonide results in negligible serum concentrations of ciclesonide. However, the known active metabolite (des‑ciclesonide) is detected in the serum of some patients after nasal inhalation of ciclesonide. The bioanalytical assay used has a lower limit of quantification of 25 pg/mL and 10 pg/mL, for ciclesonide and des-ciclesonide, respectively. In healthy adults treated for 2 weeks with 50 to 800 mcg of ciclesonide nasal spray daily (n = 6 in each treatment group), the peak serum concentrations of des-ciclesonide in all subjects were found to be below 30 pg/mL. Of those treated with 800 mcg and 400 mcg daily, 100% and 67% had detectable levels of des-ciclesonide, respectively. With daily doses of ≤ 200 mcg, detectable serum levels of des-ciclesonide were not observed. The low systemic exposure following ciclesonide nasal spray administration was confirmed in a crossover study in 29 healthy adults. The median maximum observed concentration was less than 10 pg/mL and 602 pg/mL following a single dose of ciclesonide nasal spray (300 mcg) and orally inhaled ciclesonide (320 mcg), respectively. Animal Data A study with 14 C-ciclesonide showed milk exposure of rat pups to 0.006% of the dose secreted in milk. 8.4 Pediatric Use The safety and effectiveness for seasonal and perennial allergic rhinitis in children 12 years of age and older have been established. The efficacy of OMNARIS Nasal Spray in patients 6 to 11 years of age for treatment of the symptoms of seasonal allergic rhinitis was demonstrated in one study in patients 6 to 11 years of age with seasonal allergic rhinitis. The efficacy of OMNARIS Nasal Spray for the treatment of the symptoms of seasonal allergic rhinitis in patients 5 years of age and younger has not been established. The efficacy of OMNARIS Nasal Spray for the treatment of the symptoms of perennial allergic rhinitis in patients 11 years of age and younger has not been established [see Clinical Studies ( 14.1 )] . The safety of OMNARIS Nasal Spray in children 2 to 11 years of age was evaluated in 4 controlled clinical studies of 2 to 12 weeks duration [see Clinical Pharmacology ( 12.2 ), Clinical Studies ( 14.1 ), and Adverse Reactions ( 6 )] . Controlled clinical studies have shown that intranasal 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 intranasal corticosteroids, including the impact on final adult height, are unknown. The potential for “catch-up” growth following discontinuation of treatment with intranasal corticosteroids has not been adequately studied. The growth of pediatric patients receiving intranasal corticosteroids, including OMNARIS Nasal Spray, should be monitored routinely (e.g., via stadiometry). A 52-week, multicenter, double-blind, randomized, placebo-controlled parallel-group study was conducted to assess the effect of orally inhaled ciclesonide 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 study 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 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 intranasal corticosteroids, each patient should be titrated to the lowest dose that effectively controls his/her symptoms. 8.5 Geriatric Use Clinical studies of OMNARIS Nasal Spray 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. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
