Adverse Reactions

6 ADVERSE REACTIONS Adverse reactions associated with ophthalmic steroids include elevated intraocular pressure, which may be associated with infrequent optic nerve damage, visual acuity and field defects, posterior subcapsular cataract formation, delayed wound healing and secondary ocular infection from pathogens including herpes simplex, and perforation of the globe where there is thinning of the cornea or sclera. The most common adverse drug reactions reported in the clinical trials (2-5%) were anterior chamber inflammation, eye pain, and foreign body sensation.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation. While glucocorticoids are known to bind to and activate the glucocorticoid receptor, the molecular mechanisms involved in glucocorticoid/glucocorticoid receptor‑dependent modulation of inflammation are not clearly established. However, corticosteroids are thought to inhibit prostaglandin production through several independent mechanisms. 12.3 Pharmacokinetics Loteprednol etabonate is lipid soluble and can penetrate into cells. Loteprednol etabonate is synthesized through structural modifications of prednisolone-related compounds so that it will undergo a predictable transformation to an inactive metabolite. Based upon in vivo and in vitro preclinical metabolism studies, loteprednol etabonate undergoes extensive metabolism to the inactive carboxylic acid metabolites, PJ-91 and PJ-90. The systemic exposure to loteprednol etabonate following ocular administration of Loteprednol Etabonate Ophthalmic Gel has not been studied in humans.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term animal studies have not been conducted to evaluate the carcinogenic potential of loteprednol etabonate. Loteprednol etabonate was not genotoxic in vitro in the Ames test, the mouse lymphoma tk assay, or in a chromosome aberration test in human lymphocytes, or in vivo in the single dose mouse micronucleus assay. Treatment of female and male rats with doses ≥ 25 mg/kg/day of loteprednol etabonate (152 times the RHOD based on body surface area, assuming 100% absorption) prior to and during mating caused preimplantation loss and decreased the number of live fetuses/live births. The NOAEL for fertility in rats was 5 mg/kg/day (30 times the RHOD).

Clinical Studies

14 CLINICAL STUDIES Adult Studies In two randomized, multicenter, double-masked, parallel-group, vehicle-controlled studies in 813 subjects with post-operative inflammation, Loteprednol Etabonate Ophthalmic Gel was more effective compared to its vehicle in resolving anterior chamber inflammation and pain following cataract surgery. Primary endpoints were complete resolution of anterior chamber cells (cell count of 0) and no pain at post-operative day 8. In these studies, Loteprednol Etabonate Ophthalmic Gel had a statistically significant higher incidence of subjects with complete clearing of anterior chamber cells (31% vs. 14-16%) and were pain-free at post-operative day 8 (73-76% vs. 42-46%). Pediatric Study The safety and effectiveness of Loteprednol Etabonate Ophthalmic Gel were evaluated in a pediatric study of patients from birth to less than 11 years of age (mean age of 3 years) undergoing cataract surgery. Patients were randomized to receive either Loteprednol Etabonate Ophthalmic Gel (54 patients) or prednisolone acetate ophthalmic suspension 1% (53 patients) four times daily for 14 days. At Day 14, the percentages of patients with complete clearing of anterior chamber inflammation were 57% in the Loteprednol Etabonate Ophthalmic Gel group and 63% in the prednisolone group.

Geriatric Use

8.5 Geriatric Use No overall differences in safety and effectiveness have been observed between elderly and younger patients.

Pediatric Use

8.4 Pediatric Use The safety and effectiveness of LOTEMAX have been established in the pediatric population. Use of LOTEMAX in this population is supported by evidence from adequate and well-controlled trials of LOTEMAX in adults with additional data from a safety and efficacy trial in pediatric patients from birth to 11 years of age [see Clinical Studies ( 14 )].

Pregnancy

8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies with loteprednol etabonate in pregnant women. Loteprednol etabonate produced teratogenicity at clinically relevant doses in the rabbit and rat when administered orally during pregnancy. Loteprednol etabonate produced malformations when administered orally to pregnant rabbits at doses ≥ 1.2 times the recommended human ophthalmic dose (RHOD) and to pregnant rats at doses ≥ 30 times the RHOD. In pregnant rats receiving oral doses of loteprednol etabonate during the period equivalent to the last trimester of pregnancy through lactation in humans, survival of offspring was reduced at doses ≥ 3 times the RHOD. Maternal toxicity was observed in rats at doses ≥ 304 times the RHOD, and a maternal no observed adverse effect level (NOAEL) was established at 30 times the RHOD. 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. Data Animal Data Embryofetal studies were conducted in pregnant rabbits administered loteprednol etabonate by oral gavage on gestation days 6 to 18, to target the period of organogenesis. Loteprednol etabonate produced fetal malformations at doses ≥ 0.1 mg/kg (1.2 times the recommended human ophthalmic dose (RHOD) based on body surface area, assuming 100% absorption). Spina bifida (including meningocele) was observed at doses ≥ 0.1 mg/kg, and exencephaly and craniofacial malformations were observed at doses ≥ 0.4 mg/kg (4.9 times the RHOD). At 3 mg/kg (36 times the RHOD), loteprednol etabonate was associated with increased incidences of abnormal left common carotid artery, limb flexures, umbilical hernia, scoliosis, and delayed ossification. Abortion and embryofetal lethality (resorption) occurred at doses ≥ 6 mg/kg (73 times the RHOD). A NOAEL for developmental toxicity was not established in this study. The NOAEL for maternal toxicity in rabbits was 3 mg/kg/day. Embryofetal studies were conducted in pregnant rats administered loteprednol etabonate by oral gavage on gestation days 6 to 15, to target the period of organogenesis. Loteprednol etabonate produced fetal malformations, including absent innominate artery at doses ≥ 5 mg/kg (30 times the RHOD); and cleft palate, agnathia, cardiovascular defects, umbilical hernia, decreased fetal body weight and decreased skeletal ossification at doses ≥ 50 mg/kg (304 times the RHOD). Embryofetal lethality (resorption) was observed at 100 mg/kg (608 times the RHOD). The NOAEL for developmental toxicity in rats was 0.5 mg/kg (3 times the RHOD). Loteprednol etabonate was maternally toxic (reduced body weight gain) at doses of ≥ 50 mg/kg/day. The NOAEL for maternal toxicity was 5 mg/kg. A peri-/postnatal study was conducted in rats administered loteprednol etabonate by oral gavage from gestation day 15 (start of fetal period) to postnatal day 21 (the end of lactation period). At doses ≥ 0.5 mg/kg (3 times the clinical dose), reduced survival was observed in live-born offspring. Doses ≥ 5 mg/kg (30 times the RHOD) caused umbilical hernia/incomplete gastrointestinal tract. Doses ≥ 50 mg/kg (304 times the RHOD) produced maternal toxicity (reduced body weight gain, death), decreased number of live-born offspring, decreased birth weight, and delays in postnatal development. A developmental NOAEL was not established in this study. The NOAEL for maternal toxicity was 5 mg/kg.
