LATISSE (Page 2 of 5)

6.1 Clinical Trial s 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.

The following information is based on clinical trial results from a multicenter, double-masked, randomized, vehicle-controlled, parallel study including 278 adult patients for four months of treatment.

The most frequently reported adverse reactions were eye pruritus, conjunctival hyperemia, skin hyperpigmentation, ocular irritation, dry eye symptoms, and periorbital erythema. These reactions occurred in less than 4% of patients. Additional adverse reactions seen in clinical trials experience include foreign body sensation, hair growth abnormal, and iris hyperpigmentation.

Additional adverse reactions reported with bimatoprost ophthalmic solution (LUMIGAN ® ) for the reduction of intraocular pressure include, ocular dryness, visual disturbance, ocular burning, eye pain, blepharitis, cataract, superficial punctate keratitis, eye discharge, tearing, photophobia, allergic conjunctivitis, asthenopia, conjunctival edema, iritis, infections (primarily colds and upper respiratory tract infections), headaches, and asthenia.

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of LATISSE ® . 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. The reactions include: dry skin of the eyelid and/or periocular area, eye swelling, eyelid edema, hordeolum, hypersensitivity (local allergic reactions), lacrimation increased, madarosis and trichorrhexis (temporary loss of a few lashes to loss of sections of eyelashes, and temporary eyelash breakage, respectively), periorbital and lid changes associated with a deepening of the eyelid sulcus, rash (including macular and erythematous), skin discoloration (periorbital), trichiasis, and vision blurred.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

There are no adequate and well-controlled studies of LATISSE ® (bimatoprost ophthalmic solution) 0.03% administration in pregnant women. There is no increase in the risk of major birth defects or miscarriages based on bimatoprost postmarketing experience.

In embryofetal development studies, administration of bimatoprost to pregnant mice and rats during organogenesis, resulted in abortion and early delivery at oral doses at least 33 times (mice) or 94 times (rats) the human exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on the area under the curve (AUC). These adverse effects were not observed at 2.6 times (mice) and 47 times (rats) the human exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC.

In pre/postnatal development studies, administration of bimatoprost to pregnant rats from organogenesis to the end of lactation resulted in reduced gestation length and fetal body weight, and increased fetal and pup mortality at oral doses at least 41 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC. No adverse effects were observed in rat offspring at exposures estimated at 14 times the human exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC.

Because animal reproductive studies are not always predictive of human response LATISSE ® 0.03% should be administered during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Data

Animal Data

In an embryofetal development rat study, abortion was observed in pregnant rats administered bimatoprost orally during organogenesis at 0.6 mg/kg/day (94 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC). The No Observed Adverse Effect Level (NOAEL) for abortion was 0.3 mg/kg/day (estimated at 47 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily based on AUC). No abnormalities were observed in rat fetuses at doses up to 0.6 mg/kg/day.

In an embryofetal development mouse study, abortion and early delivery were observed in pregnant mice administered bimatoprost orally during organogenesis at doses greater than or equal to 0.3 mg/kg/day (33 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC). The NOAEL for abortion and early delivery was 0.1 mg/kg/day (2.6 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC) . No abnormalities were observed in mouse fetuses at doses up to 0.6 mg/kg/day (72 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC).

In a pre/postnatal development study, treatment of pregnant rats with bimatoprost orally from gestation day 7 to lactation day 20 resulted in reduced gestation length, increased late resorptions, fetal deaths, and postnatal pup mortality, and reduced pup body weight at doses greater than or equal to 0.3 mg/kg/day. These effects were observed at exposures at least 41 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC. The NOAEL for postnatal development and mating performance of the offspring was 0.1 mg/kg/day (estimated at 14 times the human systemic exposure following topical ophthalmic administration of bimatoprost 0.03% to the cornea or conjunctival sac bilaterally once daily, based on AUC).

8.2 Lactation

Risk Summary

It is not known whether topical ocular treatment with LATISSE ® 0.03% could result in sufficient systemic absorption to produce detectable quantities in human milk. In animal studies, bimatoprost has been shown to be present in breast milk of lactating rats at an intravenous dose (i.e., 1 mg/kg) 324 times the recommended human ophthalmic dose (on a mg/m2 basis), however no animal data is available at clinically relevant doses.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for LATISSE ® 0.03% and any potential adverse effects on the breastfed child from LATISSE ® 0.03%.

8.4 Pediatric Use

Use of LATISSE ® was evaluated in a sixteen week double-masked, randomized, vehicle-controlled study conducted in pediatric patients who were post-chemotherapy or had alopecia areata, and adolescents who had hypotrichosis with no associated medical condition. No new safety issues were observed. The results of the Global Eyelash Assessment are provided in Table 1.
