ARLINGTON, Mass., May 03, 2022 (GLOBE NEWSWIRE) -- Kala Pharmaceuticals, Inc., (NASDAQ:KALA), a commercial-stage biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies for diseases of the eye, today announced that the largest Pharmacy Benefit Manager in the United States has added EYSUVIS (loteprednol etabonate ophthalmic suspension) 0.25% as a covered brand on its commercial formularies, effective May 1, 2022. This adds 28.5 million commercial lives to EYSUVIS coverage, bringing total commercial coverage to 155.3 million lives, or 92% of total commercial lives.

Also today, Kala announced that Humana, one of the largest Medicare health plans in the United States, has added EYSUVIS as a Preferred Brand on its Medicare formularies, effective June 1, 2022. This adds approximately 7 million Medicare lives to EYSUVIS coverage, bringing total EYSUVIS Medicare coverage to 14.1 million lives, or approximately 30% of all Medicare lives.

“We are excited to announce this additional payer coverage, which brings our commercial access to 92% of covered lives and doubles our Medicare Part D coverage. This is an important step toward our goal of securing broad commercial and Medicare access for EYSUVIS and we expect the additional coverage will translate into higher prescription fulfillment rates and accelerated growth,” said Todd Bazemore, President and Chief Operating Officer of Kala Pharmaceuticals. “Earlier this year, we secured coverage with several large commercial and Medicare Part D plans and, together with these additions, we have now achieved total EYSUVIS coverage for more than 169 million lives. We continue to engage with other commercial and Medicare Part D health plans and anticipate further formulary additions in 2022.”

About EYSUVIS
EYSUVIS (loteprednol etabonate ophthalmic suspension) 0.25% is approved for the short-term (up to two weeks) treatment of the signs and symptoms of dry eye disease. EYSUVIS utilizes Kala's AMPPLIFY® mucus-penetrating particle (MPP) Drug Delivery Technology to enhance penetration of loteprednol etabonate (LE) into target tissue of the ocular surface. In preclinical studies, the AMPPLIFY Drug Delivery Technology increased delivery of LE into target ocular tissues more than three-fold compared to an active LE comparator by facilitating penetration through the tear film mucins. EYSUVIS was approved by the FDA on October 26, 2020. Kala believes that EYSUVIS' broad mechanism of action, rapid onset of relief of both signs and symptoms, favorable tolerability and safety profile and the potential to be complementary to existing therapies, offer a differentiated product profile for the short-term treatment of dry eye disease, including the management of dry eye flares.

EYSUVIS, as with other ophthalmic corticosteroids, is contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures. The initial prescription and each renewal of the medication order should be made by a physician only after examination of the patient with the aid of magnification, such as slit lamp biomicroscopy, and, where appropriate, fluorescein staining. Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, as well as defects in visual acuity and fields of vision. Corticosteroids should be used with caution in the presence of glaucoma. Renewal of the medication order should be made by a physician only after examination of the patient and evaluation of the IOP. Use of corticosteroids may result in posterior subcapsular cataract formation. Use of corticosteroids may suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions, corticosteroids may mask infection or enhance existing infection. Use of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution. Use of ocular corticosteroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Fungal infections of the cornea are particularly prone to develop coincidentally with long-term local corticosteroid application. Fungus invasion must be considered in any persistent corneal ulceration where a corticosteroid has been used or is in use. The most common adverse drug reaction following the use of EYSUVIS for two weeks was instillation site pain, which was reported in 5% of patients.
