In commenting on the agreement, Mark L. Baum, Chairman and Chief Executive Officer of Harrow, said, "We believe the value this agreement provides to eligible participants will open access to IHEEZO for the U.S. hospital market. According to the U.S. Centers for Disease Control and Prevention, approximately 2.4 million annual emergency room visits in U.S. hospitals are due to eye-related problems, including the removal of foreign bodies and other acute conditions, many of which require anesthetizing the eye. Consistent with our commitment to ensure access and affordability to our products, with around 44% of U.S. hospitals participating in the Apexus 340B Prime Vendor Program, we are thrilled about the potential benefits we see from our new relationship, especially for vulnerable populations."

The 340B Prime Vendor Program, managed by Apexus, is a contract awarded by the Health Resources and Services Administration ("HRSA"), an agency of the U.S. Department of Health and Human Services, which is responsible for administering the 340B Drug Pricing Program. As the Prime Vendor, Apexus contracts with manufacturers and distributors to help ensure access to discounted medications, provides 340B education to all stakeholders, and helps support program integrity through technical assistance.

About ILEVRO® (nepafenac ophthalmic suspension) 0.3%

ILEVRO® (nepafenac ophthalmic suspension) 0.3%, a nonsteroidal, anti-inflammatory eye drop indicated for pain and inflammation associated with cataract surgery.

INDICATIONS AND USAGE

ILEVRO® 0.3% is indicated for the treatment of pain and inflammation associated with cataract surgery.

CONTRAINDICATIONS

ILEVRO® 0.3% is contraindicated in patients with previously demonstrated hypersensitivity to any of the ingredients in the formula or to other nonsteroidal anti-inflammatory drugs (NSAIDs).

WARNINGS AND PRECAUTIONS

Increased Bleeding Time. With some NSAIDs including ILEVRO® 0.3%, there exists the potential for increased bleeding time due to interference with thrombocyte aggregation. There have been reports that ocularly applied nonsteroidal anti-inflammatory drugs may cause increased bleeding of ocular tissues (including hyphema) in conjunction with ocular surgery. It is recommended that ILEVRO® 0.3% be used with caution in patients with known bleeding tendencies or who are receiving other medications which may prolong bleeding time.

Delayed Healing. Topical NSAIDs including ILEVRO® 0.3%, may slow or delay healing. Topical corticosteroids are also known to slow or delay healing. Concomitant use of topical NSAIDs and topical steroids may increase the potential for healing problems.

Corneal Effects. Use of topical NSAIDs may result in keratitis. In some susceptible patients, continued use of topical NSAIDs may result in epithelial breakdown, corneal thinning, corneal erosion, corneal ulceration, or corneal perforation. These events may be sight threatening. Patients with evidence of corneal epithelial breakdown should immediately discontinue use of topical NSAIDs including ILEVRO® 0.3% and should be closely monitored for corneal health.

Postmarketing experience with topical NSAIDs suggests that patients with complicated ocular surgeries, corneal denervation, corneal epithelial defects, diabetes mellitus, ocular surface diseases (e.g., dry eye syndrome), rheumatoid arthritis, or repeat ocular surgeries within a short period of time may be at increased risk for corneal adverse events, which may become sight threatening. Topical NSAIDs should be used with caution in these patients. Postmarketing experience with topical NSAIDs also suggests that use more than 1 day prior to surgery or use beyond 14 days post-surgery may increase patient risk and severity of corneal adverse events.

Contact Lens Wear. ILEVRO® 0.3% should not be administered while using contact lenses.

ADVERSE REACTIONS

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 the rates in the clinical studies of another drug and may not reflect the rates observed in practice.

Serious and Otherwise Important Adverse Reactions. The following adverse reactions are discussed in greater detail in other sections of labeling: (1) Increased Bleeding Time, (2) Delayed Healing and (3) Corneal Effects.

Ocular Adverse Reactions. The most frequently reported ocular adverse reactions following cataract surgery were capsular opacity, decreased visual acuity, foreign body sensation, increased intraocular pressure, and sticky sensation. These reactions occurred in approximately 5 to 10% of patients. Other ocular adverse reactions occurring at an incidence of approximately 1 to 5% included conjunctival edema, corneal edema, dry eye, lid margin crusting, ocular discomfort, ocular hyperemia, ocular pain, ocular pruritus, photophobia, tearing and vitreous detachment. Some of these reactions may be the consequence of the cataract surgical procedure.

Non-Ocular Adverse Reactions. Non-ocular adverse reactions reported at an incidence of 1 to 4% included headache, hypertension, nausea/vomiting, and sinusitis.
