Dosage and Administration

2 DOSAGE AND ADMINISTRATION One drop of OXERVATE in the affected eye(s), 6 times per day at 2-hour intervals, for eight weeks. ( 2.1 ) 2.1 General Dosing Information Contact lenses should be removed before applying OXERVATE and may be reinserted 15 minutes after administration. If a dose is missed, treatment should be continued as normal, at the next scheduled administration. If more than one topical ophthalmic product is being used, administer the eye drops at least 15 minutes apart to avoid diluting products. Administer OXERVATE 15 minutes prior to using any eye ointment, gel or other viscous eye drops. 2.2 Recommended Dosage and Dose Administration Instill one drop of OXERVATE in the affected eye(s), 6 times a day at 2-hour intervals for eight weeks. 2.3 Preparation for Administration Remove the weekly carton(s) containing OXERVATE vials from the insulated pack and store it for up to 14 days in a refrigerator (no later than 5 hours from when you receive the medicine from your pharmacy). OXERVATE is stored in a freezer at the pharmacy. If treatment is started immediately after receiving the weekly carton, wait until the first vial is thawed (this could take up to 30 minutes when kept at room temperature up to 77°F (25°C)). Do not shake the vial. Follow Steps 1 to 19 each day you use OXERVATE: Take an individual vial of OXERVATE from the refrigerator in the morning and prepare it in the following way: Step 1. Wash your hands. Step 2. If you wear contact lenses, take them out before using OXERVATE. Step 3. Remove the plastic flip-off cap from the vial. Step 4. Peel-off the back of the vial adapter blister pack. Step 5. Without removing the vial adapter from its blister pack, connect it to the vial by firmly pushing it down until it snaps into place over the neck of the vial. The spike of the vial adapter should pierce through the vial’s rubber stopper. After the vial adapter has been connected correctly, do not remove it from the vial. Note: After the vial adapter is connected to the vial, OXERVATE can be stored in the refrigerator between 36°F to 46°F (2°C to 8°C) for up to 12 hours. If needed, the OXERVATE with the connected vial adapter may be stored at room temperature up to 77°F (25°C). Step 6. Remove and throw away the packaging of the vial adapter. The multi-dose vial of OXERVATE is now ready for use (1 drop in the affected eye every 2 hours six times a day). To withdraw and give each dose of OXERVATE, follow the Steps 7 to 19 : Step 7. Take a single sterile disinfectant wipe and gently clean the surface of the valve on the connector part of the vial adapter. After cleaning, wait for about 1 minute to allow the valve to dry. Step 8. Remove a pipette from its protective packaging. Step 9. Screw the pipette (clockwise) into the connector part of the vial adapter. Step 10. Make sure that the pipette plunger is pushed all the way down. Step 11. Turn the vial upside-down with the pipette still connected. Gently pull the plunger until it stops,...

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The most common adverse reactions (incidence >5%) are eye pain, ocular hyperemia, eye inflammation and increased lacrimation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Dompé U.S. Inc. at 1-833-366-7387 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. In two clinical trials of patients with neurotrophic keratitis, a total of 101 patients received cenegermin-bkbj eye drops at 20 mcg/mL at a frequency of 6 times daily in the affected eye(s) for a duration of 8 weeks. The mean age of the population was 61 to 65 years of age (18 to 95). The majority of the treated patients were female (61%). The most common adverse reaction was eye pain following instillation which was reported in approximately 16% of patients. Eye pain may arise as corneal healing occurs. Other adverse reactions occurring in 1% to 10% of OXERVATE patients included corneal deposits, foreign body sensation, ocular hyperemia, ocular inflammation, photophobia, tearing, and headache. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of OXERVATE. 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. Eye disorders : eye irritation, blepharitis (including eyelid margin crusting and eyelid edema) and corneal neovascularization.

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary There are no data from the use of OXERVATE in pregnant women to inform any drug associated risks. Administration of cenegermin-bkbj to pregnant rats or rabbits during the period of organogenesis did not produce adverse fetal effects at clinically relevant doses. In a pre- and postnatal development study, administration of cenegermin-bkbj to pregnant rats throughout gestation and lactation did not produce adverse effects in offspring at clinically relevant doses. Data Animal Data In embryofetal development studies, daily subcutaneous administration of cenegermin-bkbj to pregnant rats and rabbits throughout the period of organogenesis produced a slight increase in post-implantation loss at doses greater than or equal to 42 mcg/kg/day (267 times the MRHOD). A no observed adverse effect level (NOAEL) was not established for post-implantation loss in either species. In rats, hydrocephaly and ureter anomalies were observed each in one fetuses at 267 mcg/kg/day (1709 times the MRHOD). In rabbits, cardiovascular malformations, including ventricular and atrial septal defects, enlarged heart and aortic arch dilation were observed each in one fetuses at 83 mcg/kg/day (534 times the MRHOD). No fetal malformations were observed in rats and rabbits at doses of 133 mcg/kg/day and 42 mcg/kg/day, respectively. In a pre- and postnatal development study, daily subcutaneous administration of cenegermin-bkbj to pregnant rats during the period of organogenesis and lactation did not affect parturition and was not associated with adverse toxicity in offspring at doses up to 267 mcg/kg/day. In parental rats and rabbits, an immunogenic response to cenegermin-bkbj was observed. Given that cenegermin-bkbj is a heterologous protein in animals, this response may not be relevant to humans.
