Indications & Usage Section
DURYSTA ®  (bimatoprost intracameral implant) is indicated for the reduction of intraocular pressure (IOP) in patients with open angle glaucoma (OAG) or ocular hypertension (OHT).
DURYSTAÂ is a prostaglandin analog indicated for the reduction of intraocular pressure (IOP) in patients with open angle glaucoma (OAG) or ocular hypertension (OHT). (1 )
Dosage & Administration Section
- For ophthalmic intracameral administration. (
2.1 )- The intracameral administration should be carried out under standard aseptic conditions. (
2.2 )
DURYSTA is an ophthalmic drug delivery system for a single intracameral administration of a biodegradable implant. DURYSTA should not be readministered to an eye that received a prior DURYSTA. Â
The intracameral injection procedure must be performed under magnification that allows clear visualization of the anterior chamber structures and should be carried out using standard aseptic conditions for intracameral procedures, with the patient’s head in a stabilized position. The eye should not be dilated prior to the procedure.
Remove the foil pouch from the carton and examine for damage. Then, open the foil pouch over a sterile field and gently drop the applicator on a sterile tray. Once the foil pouch is opened, use promptly.
Figure 1
Perform a detailed visual inspection of the applicator, including ensuring that the actuator button has not been depressed, and the safety tab is in place. Carefully remove the plastic safety cap taking care to avoid contacting the needle tip. Inspect the needle tip for damage under magnification prior to use; the implant retention plug may be visible in the bevel and should not be removed.
Prior to use, remove the safety tab by pulling it out perpendicular to the long axis of the applicator (refer to Figure 1a above). Do not twist or bend the tab.
Stabilize the eye as the needle is advanced through the cornea. Enter the anterior chamber with the needle bevel visible through clear cornea. Enter parallel to the iris plane, adjacent to the limbus through clear cornea in the superotemporal quadrant.
The needle should be inserted approximately 2 bevel lengths with the bevel completely within the anterior chamber; avoid positioning the needle bevel directly over the pupil. Ensure the needle is not bent before depressing the actuator button. See Figure 2.
Â
Figure 2
Depress the back half of the actuator button (refer to Figure 1b above) firmly until an audible and/or palpable click is noted.
Following the release of the implant, remove the needle via the same track in which it was inserted and tamponade the opening. The implant should not be left in the corneal injection track.
Check the injection site for leaks; make sure that it is self-sealing and the anterior chamber is formed.
After injection, do not recap the needle. Dispose of the used applicator in a sharps disposal container and in accordance with local requirements.
Instruct the patient to remain upright for at least 1 hour after the procedure so the implant can settle.
Some degree of eye redness and discomfort is expected following administration. However, it is recommended to instruct patients that if the eye becomes progressively red, sensitive to light, painful, or develops a change in vision, they should immediately contact the physician.

Contraindications Section
- Ocular or periocular infections (
4.1 )- Corneal endothelial cell dystrophy (
4.2 )- Prior corneal transplantation (
4.3 )- Absent or ruptured posterior lens capsule (
4.4 )- Hypersensitivity (
4.5 )
DURYSTA is contraindicated in patients with active or suspected ocular or periocular infections.
DURYSTA is contraindicated in patients with corneal endothelial cell dystrophy (e.g., Fuchs’ Dystrophy) [see Warnings and Precautions ( 5.1 )].
DURYSTA is contraindicated in patients with prior corneal transplantation, or endothelial cell transplants [e.g., Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK)].
DURYSTA is contraindicated in patients whose posterior lens capsule is absent or ruptured, due to the risk of implant migration into the posterior segment. Laser posterior capsulotomy in pseudophakic patients is not a contraindication for DURYSTA use if the intraocular lens fully covers the opening in the posterior capsule.
DURYSTA is contraindicated in patients with hypersensitivity to bimatoprost or to any other components of the product [see Adverse Reactions ( 6.1 )].
Warnings And Precautions Section
- Endothelial cell loss: Due to possible corneal endothelial cell loss, administration of DURYSTA should be limited to a single implant per eye without retreatment. (
5.1 )- Corneal Adverse Reactions: DURYSTA has been associated with corneal adverse reactions and risks are increased with multiple implants. Use caution in patients with limited corneal endothelial cell reserve. (
5.1 )- Iridocorneal Angle: DURYSTA should be used with caution in patients with narrow angles or anatomical angle obstruction. (
5.2 )
The presence of DURYSTA implants has been associated with corneal adverse reactions and increased risk of corneal endothelial cell loss. Administration of DURYSTA should be limited to a single implant per eye without retreatment. Caution should be used when prescribing DURYSTA in patients with limited corneal endothelial cell reserve.
Following administration with DURYSTA, the intracameral implant is intended to settle within the inferior angle. DURYSTA should be used with caution in patients with narrow iridocorneal angles (Shaffer grade Ë‚ 3) or anatomical obstruction (e.g., scarring) that may prohibit settling in the inferior angle.
Macular edema, including cystoid macular edema, has been reported during treatment with ophthalmic bimatoprost, including DURYSTA intracameral implant. DURYSTA should be used with caution in aphakic patients, in pseudophakic patients with a torn posterior lens capsule, or in patients with known risk factors for macular edema.
Prostaglandin analogs, including DURYSTA, have been reported to cause intraocular inflammation. DURYSTA should be used with caution in patients with active intraocular inflammation (e.g., uveitis) because the inflammation may be exacerbated.
Ophthalmic bimatoprost, including DURYSTA intracameral implant, has been reported to cause changes to pigmented tissues, such as increased pigmentation of the iris. Pigmentation of the iris is likely to be permanent. Patients who receive treatment should be informed of the possibility of increased pigmentation. The pigmentation change is due to increased melanin content in the melanocytes rather than to an increase in the number of melanocytes. While treatment with DURYSTA can be continued in patients who develop noticeably increased iris pigmentation, these patients should be examined regularly.
Intraocular surgical procedures and injections have been associated with endophthalmitis. Proper aseptic technique must always be used with administering DURYSTA, and patients should be monitored following the administration.

CLINICAL TRIALS EXPERIENCE SECTION
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 most common ocular adverse reaction observed in two randomized, active-controlled clinical trials with DURYSTA in patients with OAG or OHT was conjunctival hyperemia, which was reported in 27% of patients. Other common ocular adverse reactions reported in 5-10% of patients were foreign body sensation, eye pain, photophobia, conjunctival hemorrhage, dry eye, eye irritation, intraocular pressure increased, corneal endothelial cell loss, vision blurred, and iritis. Ocular adverse reactions occurring in 1-5% of patients were anterior chamber cell, lacrimation increased, corneal edema, aqueous humor leakage, iris adhesions, ocular discomfort, corneal touch, iris hyperpigmentation, anterior chamber flare, anterior chamber inflammation, and macular edema. The following additional adverse drug reactions occurred in less than 1% of patients: hyphema, iridocyclitis, uveitis, corneal opacity, product administered at inappropriate site, corneal decompensation, cystoid macular edema, and drug hypersensitivity.
The most common nonocular adverse reaction was headache, which was observed in 5% of patients.
Use In Specific Populations Section
PREGNANCY SECTION
Risk Summary
There are no adequate and well-controlled studies of DURYSTA (bimatoprost intracameral implant) administration in pregnant women to inform a drug associated risk. Oral administration of bimatoprost to pregnant rats and mice throughout organogenesis did not produce adverse maternal or fetal effects at clinically relevant exposures. Oral administration of bimatoprost to rats from the start of organogenesis to the end of lactation did not produce adverse maternal, fetal or neonatal effects at clinically relevant exposures [see Animal Data].Â
Data
Animal Data
In an embryofetal development rat study, oral administration of bimatoprost to pregnant rats during organogenesis produced abortion at 0.6 mg/kg/day (1770-times the human systemic exposure to bimatoprost from DURYSTA, based on Cmax and a blood-to plasma partition ratio of 0.858). The No Observed Adverse Effect Level (NOAEL) for abortion was 0.3 mg/kg/day (estimated at 470-times the human systemic exposure to bimatoprost from DURYSTA, based on Cmax). No fetal abnormalities were observed at doses up to 0.6 mg/kg/day.
In an embryofetal development mouse study, oral administration of bimatoprost to pregnant mice during organogenesis produced abortion and early delivery at 0.3 mg/kg/day (2240-times the human systemic exposure to bimatoprost from DURYSTA, based on plasma Cmax level; blood-to plasma partition ratio of 0.858). The NOAEL for abortion and early delivery was 0.1 mg/kg/day (400-times the human systemic exposure to bimatoprost from DURYSTA, based on Cmax). No fetal abnormalities were observed at doses up to 0.6 mg/kg/day (5200-times the human systemic exposure to bimatoprost from DURYSTA, based on Cmax).
In a pre/postnatal development study, oral administration of bimatoprost to pregnant rats from gestation day 7 through lactation resulted in reduced gestation length, increased late resorptions, fetal deaths, and postnatal pup mortality, and reduced pup body weight at 0.3 mg/kg/day (estimated 470-times the human systemic exposure to bimatoprost from DURYSTA, based plasma Cmax and a blood-to plasma partition ratio of 0.858). No adverse effects were observed in rat offspring at 0.1 mg/kg/day (estimated 350-times the human systemic exposure to bimatoprost from DURYSTA, based on plasma Cmax).
LACTATION SECTION
Risk Summary
There is no information regarding the presence of bimatoprost in human milk, the effects on the breastfed infants, or the effects on milk production. In animal studies, topical bimatoprost has been shown to be excreted in breast milk. Because many drugs are excreted in human milk, caution should be exercised when DURYSTA is administered to a nursing woman.
The developmental and health benefits of breastfeeding should be considered, along with the mother's clinical need for DURYSTA and any potential adverse effects on the breastfed child from DURYSTA.
PEDIATRIC USE SECTION
Safety and effectiveness of DURYSTA in pediatric patients have not been established.
GERIATRIC USE SECTION
No overall differences in safety or effectiveness have been observed between elderly and other adult patients.
Description Section
DURYSTA is a sterile intracameral implant containing 10 mcg of bimatoprost, a prostaglandin analog, in a solid polymer sustained-release drug delivery system (DDS). The drug delivery system consists of poly (D,L-lactide), poly (D,L-lactide-co-glycolide), poly (D,L-lactide) acid end, and polyethylene glycol 3350. DURYSTA is preloaded into a single-use, DDS applicator to facilitate injection of the rod-shaped implant directly into the anterior chamber of the eye. The chemical name for bimatoprost is (Z)-7-[(1R,2R,3R,5S)-3,5-dihydroxy-2-[(1E,3S)-3-hydroxy-5-phenyl-1-pentenyl]cyclopentyl]-N-ethyl-5-heptenamide, and its molecular weight is 415.57. Its molecular formula is C25H37NO4. Its structural formula is:
Bimatoprost is a white to off-white powder, soluble in ethyl alcohol and methyl alcohol and slightly soluble in water. The polymer matrix slowly degrades to lactic acid and glycolic acid.
Clinical Pharmacology Section
MECHANISM OF ACTION SECTION
Bimatoprost, a prostaglandin analog, is a synthetic structural analog of prostaglandin with ocular hypotensive activity. Bimatoprost is believed to lower IOP in humans by increasing outflow of aqueous humor through both the trabecular meshwork (conventional) and uveoscleral routes (unconventional). Elevated IOP presents a major risk factor for glaucomatous field loss. The higher the level of IOP, the greater the likelihood of optic nerve damage and visual field loss.
PHARMACOKINETICS SECTION
After a single administration of DURYSTA, bimatoprost concentrations were below the lower limit of quantitation (0.001Â ng/mL) in the majority (approximately 92%) of patients. The maximum bimatoprost concentration observed in any patient was 0.00224 ng/mL. Bimatoprost acid concentrations were also below the lower limit of quantitation (0.01Â ng/mL) in almost all (approximately 99%) of patients.
Nonclinical Toxicology Section
CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION
Carcinogenesis
Bimatoprost was not carcinogenic in either mice or rats when administered by oral gavage at doses up to 2Â mg/kg/day and 1Â mg/kg/day respectively for 104 weeks (approximately 3100 and 1700Â times, respectively, the maximum human exposure [based on plasma Cmax levels; blood-to-plasma partition ratio of 0.858]).
Mutagenesis
Bimatoprost was not mutagenic or clastogenic in the Ames test, in the mouse lymphoma test, or in the in vivo mouse micronucleus tests.
Impairment of Fertility
Bimatoprost did not impair fertility in male or female rats up to doses of 0.6 mg/kg/day (1770-times the maximum human exposure, based on plasma Cmax; blood-to-plasma partition ratio of 0.858).
Clinical Studies Section
Efficacy was evaluated in two multicenter, randomized, parallel-group, controlled 20-month (including 8-month extended follow-up) studies of DURYSTA compared to twice daily topical timolol 0.5% drops, in patients with OAG or OHT. DURYSTA demonstrated an IOP reduction of approximately 5-8 mmHg in patients with a mean baseline IOP of 24.5 mmHg (see Figures 3 and 4).
