5 WARNINGS AND PRECAUTIONS
5.1 Potential for Eye Injury and Contamination
To minimize eye injury and contamination of the dropper tip and solution, care should be taken not to touch the eyelids or surrounding areas with the dropper tip of the bottle. Keep bottle tightly closed when not in use.
5.2 Contact Lens Use
Patients should be advised not to wear a contact lens if their eye is red.
LASTACAFT® should not be used to treat contact lens-related irritation.
LASTACAFT® should not be instilled while wearing contact lenses. Remove contact lenses prior to instillation of LASTACAFT®. The preservative in LASTACAFT®, benzalkonium chloride, may be absorbed by soft contact lenses. Lenses may be reinserted after 10 minutes following administration of LASTACAFT®.
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 clinical practice.
The most frequent ocular adverse reactions, occurring in less than 4% of eyes treated with LASTACAFT®, were eye irritation, burning and/or stinging upon instillation, eye redness and eye pruritus.
The most frequent non-ocular adverse reactions, occurring in less than 3% of subjects with eyes treated with LASTACAFT®, were nasopharyngitis and headache. Some of these events were similar to the underlying disease being studied.
6.2 Postmarketing Experience
The following adverse reactions have been identified during post-approval use of LASTACAFT®. 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.
These reactions include eye discharge, eye swelling, erythema of eyelid, eyelid edema, lacrimation increased, vision blurred, hypersensitivity reactions including swelling of the face or allergic dermatitis, and somnolence.
8 USE IN SPECIFIC POPULATIONS
There are no adequate and well-controlled studies with LASTACAFT® in pregnant women to inform a drug associated risk. There are limited data with the use of alcaftadine eye drops in pregnant women.
In embryofetal studies in rats and rabbits, oral administration of alcaftadine during the period of organogenesis did not produce maternal or embryofetal toxicity at clinically relevant doses.
Advise pregnant women of a potential risk to the fetus and mother. LASTACAFT® should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus and mother. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4%, and of miscarriage is 15 to 20%, of clinically recognized pregnancies.
In rats, oral administration of 5, 20 or 40 mg/kg/day alcaftadine during the period of organogenesis (gestational days 6 – 16) caused maternal lethality at doses of 40 mg/kg. The no observed adverse effect level (NOAEL) for maternal toxicity was 20 mg/kg/day (an exposure 230-times higher than that at the maximum recommended human ophthalmic dose [MRHOD], based on AUC). There were no adverse embryofetal effects up to a dose of 20 mg/kg.
In rabbits, oral administration of 10, 40 or 80 mg/kg/day alcaftadine during the period of organogenesis (gestational days 6 – 18) caused no maternal toxicity or adverse embryofetal effects up to a dose of 80 mg/kg/day (an exposure 8819-times higher than that at the MRHOD, based on AUC).
Daily oral doses of 20 and 30 mg/kg/day alcaftadine administered to rats from Day 6 of pregnancy until Day 20 postpartum produced lower pup weights in offspring. No adverse effects in dams or offspring were observed at doses up to 5 mg/kg/day (a dose 286 times higher than the MRHOD, on a mg/m2 basis).
There is no information regarding the presence of LASTACAFT® in human milk, the effects on the breastfed infants, or the effects on milk production to inform risk of LASTACAFT® to an infant during lactation. The developmental and health benefits of breastfeeding should be considered, along with the mother’s clinical need for LASTACAFT®, and any potential adverse effects on the breastfed infant from LASTACAFT®.
8.4 Pediatric Use
Safety and effectiveness in pediatric patients below the age of 2 years have not been established.
LASTACAFT® (alcaftadine ophthalmic solution) is an H1 receptor antagonist, in a sterile ophthalmic solution for topical ophthalmic use.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Alcaftadine is an H1 histamine receptor antagonist and inhibitor of the release of histamine from mast cells. Decreased chemotaxis and inhibition of eosinophil activation has also been demonstrated.
Following bilateral topical ocular administration of alcaftadine ophthalmic solution, 0.25%, the mean plasma Cmax of alcaftadine was approximately 60 pg/mL and the median Tmax occurred at 15 minutes. Plasma concentrations of alcaftadine were below the lower limit of quantification (10 pg/mL) by 3 hours after dosing. The mean Cmax of the active carboxylic acid metabolite was approximately 3 ng/mL and occurred at 1 hour after dosing. Plasma concentrations of the carboxylic acid metabolite were below the lower limit of quantification (100 pg/mL) by 12 hours after dosing. There was no indication of systemic accumulation or changes in plasma exposure of alcaftadine or the active metabolite following daily topical ocular administration.
The protein binding of alcaftadine and the active metabolite are 39.2% and 62.7%, respectively.
The metabolism of alcaftadine is mediated by non-CYP450 cytosolic enzymes to the active carboxylic acid metabolite. In vitro studies showed that neither alcaftadine nor the carboxylic acid metabolite substantially inhibited reactions catalyzed by major CYP450 enzymes.
The elimination half-life of the carboxylic acid metabolite is approximately 2 hours following topical ocular administration. Based on data following oral administration of alcaftadine, the carboxylic acid metabolite is primarily eliminated unchanged in the urine.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
The carcinogenic potential of alcaftadine has not been evaluated in long-term animal studies.
Alcaftadine was not mutagenic or genotoxic in the Ames test, the mouse lymphoma assay or the mouse micronucleus assay.
Impairment of Fertility
Alcaftadine was found to have no effect on fertility of male and female rats at oral doses up to 20 mg/kg/day (an exposure 230-times higher than that at the MRHOD, based on AUC).
14 CLINICAL STUDIES
Clinical efficacy was evaluated in conjunctival allergen challenge (CAC) studies.
LASTACAFT® was more effective than its vehicle in preventing ocular itching in patients with allergic conjunctivitis induced by an ocular allergen challenge, both at 3 minutes post-dosing and at 16 hours post-dosing of LASTACAFT®.
The safety of LASTACAFT® was evaluated in a randomized clinical study of 909 subjects over a period of 6 weeks.

17 PATIENT COUNSELING INFORMATION
Potential for Eye Injury and Sterility of Dropper Tip
To minimize eye injury and contamination of the dropper tip and solution, advise patients to not touch the eyelids or surrounding areas with the dropper tip, as this may contaminate the contents.
Concomitant Use with other Ophthalmic Products
If more than one topical ophthalmic drug is being used, the drugs should be administered at least five minutes apart.
Contact Lens Use
Advise patients not to wear a contact lens if their eye is red. LASTACAFT® should not be used to treat contact lens-related irritation. Advise patients remove contact lenses prior to instillation of LASTACAFT®. The preservative in LASTACAFT®, benzalkonium chloride, may be absorbed by soft contact lenses. Lenses may be reinserted after 10 minutes following administration of LASTACAFT®.
