6.1 Clinical Trials Experience
Since 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 the VEKTIS study, a multicenter, randomized, double-masked, placebo‑controlled trial, a total of 57 patients received Verkazia dosed four times a day (QID) for 4 months. Forty-two (42) patients received Verkazia in an 8 month extension, safety follow-up of the VEKTIS study. In the NOVATIVE study, a multicenter, randomized, double-masked, placebo‑controlled trial, 39 patients received Verkazia 1 mg/mL dosed QID for one month. A total of 53 patients received Verkazia 1 mg/mL QID during a 3-month safety follow‑up. The majority of the treated patients were male (79%). The most common adverse reactions reported in greater than 5% of patients were eye pain (12%) and eye pruritus (8%) which were usually transitory and occurred during instillation (Table 1).

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no adequate and well-controlled studies of Verkazia administration in pregnant women to inform a drug-associated risk. Oral administration of cyclosporine to pregnant rats or rabbits did not produce teratogenicity at clinically relevant doses [see Data ].
Data
Animal Data
Oral administration of cyclosporine oral solution (USP) to pregnant rats or rabbits was teratogenic at maternally toxic doses of 30 mg/kg/day in rats and 100 mg/kg/day in rabbits, as indicated by increased pre- and postnatal mortality, reduced fetal weight and skeletal retardations. These doses (normalized to body weight) were approximately 320 and 2150 times higher than the daily maximum recommended human ophthalmic dose (MRHOD) of 0.015 mg/kg/day, respectively.
No adverse embryofetal effects were observed in rats or rabbits receiving cyclosporine during organogenesis at oral doses up to 17 mg/kg/day or 30 mg/kg/day, respectively (approximately 185 and 650 times higher than the MRHOD, respectively).
An oral dose of 45 mg/kg/day cyclosporine (approximately 485 times higher than MRHOD) administered to rats from Day 15 of pregnancy until Day 21 postpartum produced maternal toxicity and an increase in postnatal mortality in offspring. No adverse effects in mothers or offspring were observed at oral doses of up to
15 mg/kg/day (160 times greater than MRHOD).
8.2 Lactation
Risk Summary
There is no information regarding the presence of cyclosporine in human milk following topical administration or on the effect of Verkazia on the breastfed infants and milk production. Administration of oral cyclosporine to rats during lactation did not produce adverse effects in offspring at clinically relevant doses [see Pregnancy ( 8.1)] . The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for Verkazia and any potential adverse effects on the breast-fed child from cyclosporine.
8.3 Females and Males of Reproductive Potential
Infertility
There are no data on the effects of Verkazia on human fertility. No impairment of fertility has been reported in animals receiving intravenous cyclosporine [ see Impairment of Fertility ( 13.1) ].
8.4 Pediatric Use
Verkazia’s safety and effectiveness has been established in patients from 4 through 18 years of age.
8.5 Geriatric Use
The safety and effectiveness of Verkazia have not been studied in geriatric patients.
11 DESCRIPTION
Verkazia (cyclosporine ophthalmic emulsion) 0.1% contains a topical calcineurin inhibitor immunosuppressant. Cyclosporine is a white or almost white powder. Cyclosporine’s chemical name is Cyclo[[( E)-(2 S,3 R,4 R)-3-hydroxy-4-methyl-2-(methylamino)-6-octenoyl]-L-2-aminobutyryl- N-methylglycyl- N-methyl-L-leucyl-L-valyl- N-methyl-L-leucyl-L-alanyl-D-alanyl- N-methyl-L-leucyl- N-methyl-L-leucyl- N-methyl-L-valyl] and it has the following structure:

Verkazia ophthalmic emulsion is a sterile, unpreserved topical emulsion. It appears as a milky-white homogeneous emulsion. It has an osmolality of approximately 265 mOsmol/kg and a pH of 5-7. Each mL of Verkazia ophthalmic emulsion contains: Active: Cyclosporine 1 mg/mL. Inactives: Cetalkonium chloride, Glycerol, Medium-chain triglycerides, Poloxamer 188, Sodium Hydroxide to adjust pH, Tyloxapol and Water for Injection.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Cyclosporine is a calcineurin inhibitor immunosuppressant agent when administered systemically. Following ocular administration, cyclosporine is thought to act by blocking the release of pro-inflammatory cytokines such as IL-2. The exact mechanism of action in the treatment of VKC is not known.
12.3 Pharmacokinetics
Blood concentrations of cyclosporine were measured in 55 patients administered 1 drop of Verkazia 4 times daily in the VEKTIS Study. Blood samples were collected before administration and after 2, 4, and 12 months of administration of Verkazia. Among those patients that had quantifiable levels of cyclosporine during the study, the maximum blood level of cyclosporine was 0.67 ng/mL.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenesis
Systemic carcinogenicity studies were carried out in male and female mice and rats. In the 78-week oral (diet) mouse study, at doses of 1, 4, and 16 mg/kg/day, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value. The low dose in mice is approximately 5 times greater than MRHOD.
In the 24-month oral (diet) rat study, conducted at 0.5, 2, and 8 mg/kg/day, pancreatic islet cell adenomas significantly exceeded the control rate in the low dose level. The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related. The low dose in rats is approximately 5 times greater than MRHOD.
Mutagenesis
In genetic toxicity tests, cyclosporine has not been found to be mutagenic/genotoxic in the Ames Test, the V79-HGPRT Test, the micronucleus test in mice and Chinese hamsters, the chromosome-aberration tests in Chinese hamster bone-marrow, the mouse dominant lethal assay, and the DNA-repair test in sperm from treated mice. Cyclosporine was positive in an in vitro sister chromatid exchange (SCE) assay using human lymphocytes.
Impairment of Fertility
Oral administration of cyclosporine to rats for 12 weeks (male) and 2 weeks (female) prior to mating produced no adverse effects on fertility at doses up to 15 mg/kg/day
(160 times higher than MRHOD).
14 CLINICAL STUDIES
The safety and efficacy of Verkazia for the treatment of VKC was evaluated in two randomized, multi-center, double-masked, vehicle-controlled, clinical trials (VEKTIS Study NCT01751126 and NOVATIVE Study NCT00328653).
In the VEKTIS study, patients with severe VKC were randomized to four times daily of Verkazia 1 mg/mL or two times daily (BID) of Verkazia 1 mg/mL and vehicle group for the first 4 months (Period 1). Similarly, in the NOVATIVE study, patients with moderate to severe VKC were randomized to QID of Verkazia 1 mg/mL or QID of cyclosporine ophthalmic emulsion 0.5 mg/mL and vehicle group for the first 1 month (Period 1). In both studies, patients randomized to the vehicle group were switched to Verkazia (QID or BID) from Month 4 to Month 12 in VEKTIS Study and to cyclosporine ophthalmic emulsion 0.5 mg/mL QID or 1 mg/mL from Month 1 to Month 4 in NOVATIVE Study (Period 2).
A total of 168 and 118 patients were enrolled in the VEKTIS and NOVATIVE studies for the efficacy analyses, respectively. Patients’ age ranged from 4 through 17 years (mean age 9 years) in VEKTIS and 4 through 21 years (mean age 9 years) in NOVATIVE, with most patients being between 4 and 11 years of age (76% in VEKTIS and 80% in NOVATIVE) and male (79% in VEKTIS and 81% in NOVATIVE). Most of the patients had both limbal and tarsal forms of VKC (65% in VEKTIS and 74% in NOVATIVE). In both studies, patients had experienced VKC for a mean of 3 years prior to enrollment and all patients had a history of at least one recurrence of VKC in the year prior to study entry.
In the VEKTIS study, key efficacy evaluation was based on the change in corneal fluorescein staining (CFS) score and in itching score over 4 months. The results at each month are presented in Table 2 for the CFS score and in Table 3 for the Itching score.
Table 2: Efficacy Results of the Mean Change in Keratitis Score from Baseline at Each Visit (Full Analysis Set)
[1] Treatment differences (numbers in the middle of the horizontal lines) and 95% confidence intervals (horizontal lines) are based on ANCOVA model including baseline CFS score and the proportion of time potentially spent in taking study medication during the VKC season as covariate. For subjects that received rescue therapy during the study, all post-rescue data were imputed by the last available data observed prior to rescue initiation.
Note 1: CFS score was measured at each month using a 5-point scale (0 = no stain, and 5 = more stain).
Note 2: The Full Analysis Set included all randomized subjects that received at least one drop of study medication.
Table 3: Efficacy Results of the Mean Change in Itching Score from Baseline at Each Visit (Full Analysis Set)
[1] Treatment differences (numbers in the middle of the horizontal lines) and 95% confidence intervals (horizontal lines) are based on ANCOVA model including baseline Itching score and the proportion of time potentially spent in taking study medication as covariate. For subjects that received rescue therapy during the study, all post-rescue data were imputed by the last available data observed prior to rescue initiation.
Note 1: Itching score at each visit was measured using a Visual Analogue Scale (0 = no itch to 100 = maximal itch).
Analyses of the CFS score and Itching score at Month 1 of the efficacy evaluation period in the NOVATIVE Study also provided supporting evidence.
