`lenses. Patients who wear soft contact lenses and whose eyes are not red, should be instructed to
`wait at least five minutes after instilling PAZEO before they insert their contact lenses.
`
`6 ADVERSE REACTIONS
`6.1 Clinical 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 to rates in the clinical trials
`of another drug and may not reflect the rates observed in practice.
`
`In a randomized, double-masked, vehicle-controlled trial, patients at risk for developing allergic
`conjunctivitis received one drop of either PAZEO (N=330) or vehicle (N=169) in both eyes for 6
`weeks. The mean age of the population was 32 years (range 2 to 74 years). Thirty-five percent
`were male. Fifty-three percent had brown iris color and 23% had blue iris color. The most
`commonly reported adverse reactions occurred in 2-5% of patients treated with either PAZEO or
`vehicle. These events were blurred vision, dry eye, superficial punctate keratitis, dysgeusia and
`abnormal sensation in eye.
`
`USE IN SPECIFIC POPULATIONS
`8
`8.1 Pregnancy
`
`Reference ID: 3694617
`
`
`
`Risk Summary
`There are no adequate or well-controlled studies with PAZEO in pregnant women. Olopatadine
`caused maternal toxicity and embryofetal toxicity in rats at levels 1,080 to 14,400 times the
`maximum recommended human ophthalmic dose (MRHOD). There was no toxicity in rat
`offspring at exposures estimated to be 45 to 150 times that at MRHOD. Olopatadine should be
`used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
`
`Animal Data
`In a rabbit embryofetal study, rabbits treated orally at 400 mg/kg/day during organogenesis
`showed a decrease in live fetuses. This dose is 14,400 times the MRHOD, on a mg/m2 basis.
`
`An oral dose of 600 mg/kg/day olopatadine (10,800 times the MRHOD) was shown to be
`maternally toxic in rats, producing death and reduced maternal body weight gain. When
`administered to rats throughout organogenesis, olopatadine produced cleft palate at 60
`mg/kg/day (1080 times the MRHOD) and decreased embryofetal viability and reduced fetal
`weight in rats at 600 mg/kg/day. When administered to rats during late gestation and throughout
`the lactation period, olopatadine produced decreased neonatal survival at 60 mg/kg/day and
`reduced body weight gain in offspring at 4 mg/kg/day. A dose of 2 mg/kg/day olopatadine
`produced no toxicity in rat offspring. An oral dose of 1 mg/kg olopatadine in rats resulted in a
`range of systemic plasma area under the curve (AUC) levels that were 45 to 150 times higher
`than the observed human exposure [9.7 ng∙hr/mL] following administration of the recommended
`human ophthalmic dose.
`
`8.3 Nursing Mothers
`Olopatadine has been identified in the milk of nursing rats following oral administration. Oral
`administration of olopatadine doses at or above 4 mg/kg/day throughout the lactation period
`produced decreased body weight gain in rat offspring; a dose of 2 mg/kg/day olopatadine
`produced no toxicity. An oral dose of 1 mg/kg olopatadine in rats resulted in a range of systemic
`plasma area under the curve (AUC) levels that were 45 to 150 times higher than the observed
`human exposure [9.7 ng∙hr/mL] following administration of the recommended human
`ophthalmic dose. It is not known whether topical ocular administration could result in sufficient
`systemic absorption to produce detectable quantities in the human breast milk. Nevertheless,
`caution should be exercised when PAZEO is administered to a nursing mother.
`
`8.4 Pediatric Use
`The safety and effectiveness of PAZEO have been established in pediatric patients two years of
`age and older. Use of PAZEO in these pediatric patients is supported by evidence from adequate
`
`and well-controlled studies of PAZEO in adults and an adequate and well controlled study
`evaluating the safety of PAZEO in pediatric and adult patients.
`
`8.5 Geriatric Use
`No overall differences in safety and effectiveness have been observed between elderly and
`younger patients.
`
`11 DESCRIPTION
`
`Reference ID: 3694617
`
`
`
`PAZEO is a sterile ophthalmic solution containing olopatadine, which is a mast cell stabilizer,
`for topical administration to the eyes. Olopatadine hydrochloride is a white, crystalline,
`water-soluble powder with a molecular weight of 373.88 and a molecular formula of
`C21H23NO3•HCl.
`
`The chemical structure is presented below:
`
`Chemical Name: 11-[(Z)-3(dimethylamino) propylidene]-6-11dihydrodibenz[b,e] oxepin-2-
`acetic acid, hydrochloride
`
`Each mL of PAZEO solution contains an active ingredient [7.76 mg of olopatadine
`hydrochloride ( 7 mg olopatadine)] and the following inactive ingredients: povidone;
`hydroxypropyl-gamma-cyclodextrin; polyethylene glycol 400; hydroxypropyl methylcellulose;
`boric acid; mannitol; benzalkonium chloride 0.015% (preservative); hydrochloric acid/sodium
`hydroxide (to adjust pH); and purified water.
`
`PAZEO solution has a pH of approximately 7.2 and an osmolality of approximately 300
`mOsm/kg.
`
`12 CLINICAL PHARMACOLOGY
`
`12.1 Mechanism of Action
`Olopatadine is a mast cell stabilizer and a histamine H1 antagonist. Decreased chemotaxis and
`inhibition of eosinophil activation has also been demonstrated.
`
`12.3 Pharmacokinetics
`In healthy subjects, topical ocular dosing of 1 drop of PAZEO once daily for 7 days into both
`eyes resulted in mean ± SD (range) steady state plasma ol opatadine Cmax and AUC0-12 of 1.6 ±
`0.9 ng/mL (0.6 to 4.5 ng/mL) and 9.7 ± 4.4 ng*h/mL (3.7 to 21.2 ng*h/mL), respectively . The
`olopatadine Cmax and AUC0-12 after the first dose were similar to those measured on day 7 in
`these subjects, suggesting that there was no systemic accumulation of ol opatadine after repeated
`
` topical ocular dosing with PAZEO. The median (range) time to achieve peak olopatadine
`concentrations (Tmax) was 2.0 hours (0.25 to 4 hours). The mean ± SD (range) elimination
`half-life of olopatadine was 3.4 ± 1.2 hours (2 to 8 hours). N-oxide olopatadine (M3) was
`
`Reference ID: 3694617
`
`
`
` detected during the first 4 hours after bilateral topical ocular dosing of PAZEO in approximately
`
`half of the subjects and in less than 10% of the total plasma samples collected, at concentrations
`not exceeding 0.121 ng/mL on day 1 and 0.174 ng/mL on day 7. None of the plasma samples
`from these subjects had mono-desmethyl olopatadine (M1) concentrations that were above the
`lower limit of quantitation (0.05 ng/mL) of the PK assay.
`
`13 NONCLINICAL TOXICOLOGY
`
`13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
`
`Carcinogenicity
`Olopatadine administered orally was not carcinogenic in mice and rats in doses up to 500
`mg/kg/day and 200 mg/kg/day, respectively. Based on a 35 μL drop size and a 60 kg person,
`these doses are approximately 4,500 and 3,600 times the MRHOD, on a mg/m2 basis.
`
`Mutagenesis
`No mutagenic potential was observed when olopatadine was tested in an in vitro bacterial reverse
`mutation (Ames) test, an in vitro mammalian chromosome aberration assay or an in vivo mouse
`micronucleus test.
`
`Impairment of fertility
`Olopatadine administered at an oral dose of 400 mg/kg/day (approximately 7,200 times the
`
`MRHOD) produced toxicity in male and female rats, and resulted in a decrease in the fertility
`index and reduced implantation rate. No effects on reproductive function were observed at 50
`mg/kg/day (approximately 900 times the MRHOD).
`
`14 CLINICAL STUDIES
`The efficacy of PAZEO was established in two randomized, double-masked, placebo-controlled,
`conjunctival allergen challenge (CAC) clinical studies in patients with a history of allergic
`conjunctivitis (Studies 1 and 2).
`
`In Study 1, patients were randomized to receive one of the following study treatments: PAZEO,
`
`PATADAY, or vehicle ophthalmic solutions. In Study 2, patients were randomized to receive
`
`one of the following study treatments: PAZEO, PATADAY, PATANOL, or vehicle ophthalmic
`solutions.
`
`Patients were evaluated with an ocular itching severity score ranging from 0 (no itching) to 4
`(incapacitating itch) at several time points after CAC administration. Table 1 displays the mean
`ocular itching severity scores after ocular administration of a specific antigen using the CAC
`model in Studies 1 and 2, respectively. A one unit difference compared to vehicle is considered
`a clinically meaningful change in the ocular itching severity score.
`
`PAZEO demonstrated statistically significantly improved relief of ocular itching compared to
`vehicle at 30-34 minutes, 16 hours, and 24 hours after study treatment. PAZEO demonstrated
`statistically significantly improved relief of ocular itching compared to PATADAY at 24 hours
`after study treatment, but not at 30-34 minutes after study treatment.
