Adults and Pediatric Patients 12 Years of Age and Older The pooled RYALTRIS safety population reflects exposure to RYALTRIS at 2 sprays (2 sprays deliver a total of 1,330 mcg of olopatadine hydrochloride and 50 mcg of mometasone furoate) in each nostril twice daily in a total of 1189 patients from Studies 1 and 2 [see Clinical Studies (14)] and from three additional placebo and/or active-controlled studies in patients with allergic rhinitis. One placebo controlled study was a 52-week safety study. In this study, 393 patients were exposed to RYALTRIS for one year, and no new safety signals were observed. The RYALTRIS safety population described below reflects exposure to RYALTRIS at 2 sprays (2 sprays deliver a total of 1,330 mcg of olopatadine hydrochloride and 50 mcg of mometasone furoate) in each nostril twice daily for two weeks duration in a total of 789 patients, including 596 patients from Studies 1 and 2 [see Clinical Studies (14)], and 36 and 157 from two additional placebo and active-controlled studies in patients with seasonal allergic rhinitis. The demographics of the RYALTRIS-treated patients were 12 to 81 years of age (mean age of 40 years; 67% female; 81% White, 15% Black/African American and 3% Other). Table 1 lists adverse reactions from the safety population reported with frequencies ≥1% and more frequently than placebo in patients treated with RYALTRIS. Somnolence was reported in <1% (2 of 789) of patients treated with RYALTRIS and no patients treated with placebo.

12.3 Pharmacokinetics Absorption After repeated nasal administration of 2 sprays per nostril of RYALTRIS (2660 mcg of olopatadine hydrochloride and 100 mcg of mometasone furoate) twice daily in patients with seasonal allergic rhinitis, the mean (± standard deviation) peak plasma exposure (C max ) was 19.80 ± 7.01 ng/mL for olopatadine and 9.92 ± 3.74 pg/mL for mometasone furoate, and the mean exposure over the dosing regimen (AUC tau ) was 88.77 ± 23.87 ng/mL*hr for olopatadine and 58.40 ± 27.00 pg/mL*hr for mometasone furoate. The median time to peak exposure from a single dose was 1 hour for both olopatadine and mometasone furoate. Distribution The protein binding of olopatadine was moderate at approximately 55% in human serum and independent of drug concentration over the range of 0.1 to 1000 ng/mL. Olopatadine binds predominately to human serum albumin. The in vitro protein binding for mometasone furoate was reported to be 98% to 99% in concentration range of 5 to 500 ng/mL. Elimination Following single‑dose nasal administration of a combination of olopatadine and mometasone furoate, the mean elimination half-lives of olopatadine and mometasone furoate were 9 and 18 hours, respectively. Olopatadine is mainly eliminated through urinary excretion. Approximately 70% of a [ 14 C] olopatadine hydrochloride oral dose was recovered in urine with 17% in the feces. Of the drug‑related material recovered within the first 24 hours in the urine, 86% was unchanged olopatadine, with the balance comprised of olopatadine N-oxide and N-desmethyl olopatadine. Any absorbed drug is excreted as metabolites mostly via the bile, and to a limited extent, into the urine. Metabolism Olopatadine is not extensively metabolized. Based on plasma metabolite profiles following oral administration of [ 14 C] olopatadine, at least 6 minor metabolites circulate in human plasma. Olopatadine accounts for 77% of peak plasma total radioactivity and all metabolites amounted to <6% combined. Two of these have been identified as the olopatadine N-oxide and N-desmethyl olopatadine. In in vitro studies with cDNA-expressed human CYP isoenzymes and flavin-containing monooxygenases (FMO), N-desmethyl olopatadine (Ml) formation was catalyzed mainly by CYP3A4, while olopatadine N-oxide (M3) was primarily catalyzed by FMO1 and FMO3. Olopatadine at concentrations up to 33900 ng/mL did not inhibit the in vitro metabolism of specific substrates for CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4. The potential for olopatadine and its metabolites to act as inducers of CYP enzymes has not been evaluated. Studies have shown that any portion of a mometasone furoate dose that is swallowed and absorbed undergoes extensive metabolism to multiple metabolites. There are no major metabolites detectable in plasma. Upon in vitro incubation, one of the minor metabolites formed is 6ß-hydroxy-mometasone furoate. In human liver microsomes, the formation of the metabolite is regulated by CYP3A4. Specific Populations No pharmacokinetic studies were performed in specific populations with RYALTRIS. The pharmacokinetics of the combination of olopatadine and mometasone furoate is expected to reflect that of the individual components, as the pharmacokinetics of the combination was found to be comparable to the individual components. Patients with Hepatic Impairment: No specific pharmacokinetic study examining the effect of hepatic impairment was conducted. Metabolism of olopatadine is a minor route of elimination. Administration of a single inhaled dose of 400 mcg mometasone furoate to subjects with mild (n=4), moderate (n=4), and severe (n=4) hepatic impairment resulted in only 1 or 2 subjects in each group having detectable peak plasma concentrations of mometasone furoate (ranging from 50 to 105 pcg/mL). The observed peak plasma concentrations appeared to increase with severity of hepatic impairment; however, the numbers of detectable levels were few. Patients with Renal Impairment: The mean C max values for olopatadine following single nasal doses were not markedly different between healthy subjects (18.1 ng/mL) and patients with mild, moderate, and severe renal impairment (ranging from 15.5 to 21.6 ng/mL). Mean plasma AUC 0-12 was 2‑fold higher in patients with severe impairment (creatinine clearance <30 mL/min/1.73 m 2 ). In these patients, peak steady-state plasma concentrations of olopatadine were approximately 10‑fold lower than those observed after higher, 20mg oral doses, twice daily, which were well tolerated. The effects of renal impairment on mometasone furoate pharmacokinetics have not been adequately investigated. Pediatric Patients: RYALTRIS pharmacokinetics has not been investigated in patients under 12 years of age [see Use in Specific Populations (8.4)] . Based on population pharmacokinetic analysis among patients 12 years of age and older, the pharmacokinetics of olopatadine and mometasone furoate with RYALTRIS was not influenced by age. Male and Female Patients: Based on population pharmacokinetic analysis, the pharmacokinetics of olopatadine and mometasone furoate with RYALTRIS was not influenced by gender. Racial or Ethnic Groups: Based on population pharmacokinetic analysis, the pharmacokinetics of olopatadine and mometasone furoate with RYALTRIS was not influenced by race. Drug Interaction Studies There were no clinically relevant differences in the pharmacokinetics of either olopatadine or mometasone furoate when administered in combination compared with administration alone. Olopatadine: Drug interactions with inhibitors of liver enzymes are not anticipated because olopatadine is eliminated predominantly by renal excretion. Olopatadine did not inhibit the in vitro metabolism of specific substrates for CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4. Based on these data, drug interactions involving P450 inhibition are not expected. Due to the modest protein binding of olopatadine (55%), drug interactions through displacement from plasma proteins are also not expected. Mometasone Furoate: Inhibitors of CYP3A4: In a drug interaction study, an inhaled dose of mometasone furoate 400 mcg was given to 24 healthy subjects twice daily for 9 days, and ketoconazole 200 mg (as well as placebo) were given twice daily concomitantly on Days 4 to 9. Mometasone furoate plasma concentrations were <150 pcg/mL on Day 3 prior to coadministration of ketoconazole or placebo. Following concomitant administration of ketoconazole, 4 out of 12 subjects in the ketoconazole treatment group (n=12) had peak plasma concentrations of mometasone furoate >200 pcg/mL on Day 9 (211-324 pcg/mL).
