Use in Specific Population:

8 use in specific populations 8.1 pregnancy risk summary there are no available data on rhofade use in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. a literature article describing intranasal decongestant use in pregnant women identified a potential association between second-trimester exposure to oxymetazoline (with no decongestant exposure in the first trimester) and renal collecting system anomalies [ see data ] . in animal reproduction studies, there were no adverse developmental effects observed after oral administration of oxymetazoline hydrochloride in pregnant rats and rabbits at systemic exposures up to 3 times and 73 times, respectively, the exposure associated with the maximum recommended human dose (mrhd) [see data] . the estimated background risks of major birth defects and miscarriage for the indicated population are unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. gene
ral population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. clinical considerations fetal/neonatal a dverse r eactions following repeated use of oxymetazoline hydrochloride solution nasal spray for the treatment of nasal congestion at a dose 5 times higher than recommended, one case of fetal distress was reported in a 41-week pregnant patient. the fetal distress resolved hours later, prior to the delivery of the healthy infant. the anticipated exposures for the case are 8- to18-fold higher than plasma exposures after topical administration of rhofade. data human data no adequate and well-controlled trials of rhofade have been conducted in pregnant women. across all clinical trials of rhofade, two pregnancies were reported. one pregnancy resulted in the delivery of a healthy child. one pregnancy resulted in a spontaneous abortion, which was considered to be unrelated to the trial medication. a literature article summarizing the results of exploratory analyses of intranasal decongestant use during pregnancy identified a potential association between second-trimester exposure to oxymetazoline hydrochloride solution (with no decongestant exposure in the first trimester) and renal collecting system anomalies. animal data effects on embryo-fetal development were evaluated in rats and rabbits following oral administration of oxymetazoline hydrochloride during the period of organogenesis. oxymetazoline hydrochloride did not cause adverse effects to the fetus at oral doses up to 0.2 mg/kg/day in pregnant rats during the period of organogeneisis (3 times the mrhd on an auc comparison basis). oxymetazoline hydrochloride did not cause adverse effects to the fetus at oral doses up to 1 mg/kg/day in pregnant rabbits during the period of organogeneisis (73 times the mrhd on an auc comparison basis). maternal toxicity, such as decreased maternal body weight, was produced at the high dose of 1 mg/kg/day in pregnant rabbits and was associated with findings of delayed skeletal ossification. in a rat perinatal and postnatal development study, oxymetazoline hydrochloride was orally administered to pregnant rats once daily from gestation day 6 through lactation day 20. maternal toxicity was produced at the high dose of 0.2 mg/kg/day (3 times the mrhd on an auc comparison basis) in pregnant rats and was associated with an increase in pup mortality and reduced pup body weights. delayed sexual maturation was noted at 0.1 and 0.2 mg/kg/day (2 times the mrhd and 3 times the mrhd on an auc comparison basis, respectively). oxymetazoline hydrochloride did not have any adverse effects on fetal development at a dose of 0.05 mg/kg/day (one-half of the mrhd on an auc comparison basis). 8. 2 lactation no clinical data are available to assess the effects of oxymetazoline on the quantity or rate of breastmilk production, or to establish the level of oxymetazoline present in human breastmilk post-dose. oxymetazoline was detected in the milk of lactating rats. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for rhofade and any potential adverse effects on the breastfed child from rhofade or from the underlying maternal condition. 8.4 pediatric use safety and effectiveness of rhofade have not been established in pediatric patients below the age of 18 years. 8.5 geriatric use one hundred and ninety-three subjects aged 65 years and older received treatment with rhofade (n = 135) or vehicle (n = 58) in clinical trials. no overall differences in safety or effectiveness were observed between subjects > 65 years of age and younger subjects, based on available data. clinical studies of rhofade did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Pediatric Use:

8.4 pediatric use safety and effectiveness of rhofade have not been established in pediatric patients below the age of 18 years.

Geriatric Use:

8.5 geriatric use one hundred and ninety-three subjects aged 65 years and older received treatment with rhofade (n = 135) or vehicle (n = 58) in clinical trials. no overall differences in safety or effectiveness were observed between subjects > 65 years of age and younger subjects, based on available data. clinical studies of rhofade did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Overdosage:

10 overdosage rhofade is not for oral use. if oral ingestion occurs, seek medical advice. monitor patient closely and administer appropriate supportive measures as necessary. accidental ingestion of topical solutions (nasal sprays) containing imidazoline derivatives (e.g., oxymetazoline) in children has resulted in serious adverse events requiring hospitalization, including nausea, vomiting, lethargy, tachycardia, decreased respiration, bradycardia, hypotension, hypertension, sedation, somnolence, mydriasis, stupor, hypothermia, drooling, and coma. keep rhofade out of reach of children.

14 clinical studies rhofade was evaluated for the treatment of persistent erythema associated with rosacea in two identical, randomized, double-blind, vehicle-controlled, parallel-group clinical trials. the trials enrolled 885 subjects aged 18 years and older. overall, 90% of subjects were caucasian and 79% were female. subjects applied either rhofade or vehicle once daily for 29 days. disease severity was graded by the clinician using a 5-point clinician erythema assessment (cea) scale and by the subject on a similar 5-point subject self-assessment (ssa) scale, on which subjects scored either “moderate” or “severe” on both scales. cea and ssa were measured over a 12-hour period at equally-spaced timepoints (hours 3, 6, 9, and 12) post-dose on days 1, 15, and 29. the primary efficacy endpoint was defined as the proportion of subjects with at least a 2-grade reduction in erythema (improvement) from baseline (pre-dose on day 1) on both the cea and ssa measured at hour
s 3, 6, 9, and 12 on day 29. the results from both trials on the composite endpoint for day 29 are presented in table 2. table 2: proportion of subjects achieving composite success* on day 29 time-point (hour) trial 1 trial 2 rhofade cream (n=222) vehicle cream (n=218) rhofade cream (n = 224) vehicle cream (n=221) 3 12% 6% 14% 7% 6 16% 8% 13% 5% 9 18% 6% 16% 9% 12 15% 6% 12% 6% * composite success is defined as the proportion of subjects achieving at least a 2-grade improvement on both cea and ssa.
