Treatment for Dry Eye Disease

Kala Pharmaceuticals Announces New Drug Application for KPI-121 0.25% for Dry Eye Disease Has Been Accepted for Review by the U.S. Food and Drug Administration

WALTHAM, Mass.--(BUSINESS WIRE)--Dec. 26, 2018-- Kala Pharmaceuticals, Inc. (NASDAQ:KALA), a biopharmaceutical company focused on the development and commercialization of therapeutics using its proprietary AMPPLIFY™ mucus-penetrating particle (MPP) Drug Delivery Technology, today announced that the New Drug Application (NDA) for KPI-121 0.25%, a product candidate for the temporary relief of signs and symptoms of dry eye disease utilizing a two-week course of therapy, has been accepted for review by the United States Food and Drug Administration (FDA). The FDA has set a target action date under the Prescription Drug User Fee Act (PDUFA) of August 15, 2019. If approved, KPI-121 0.25% is expected to be the first product indicated for the temporary relief of the signs and symptoms of dry eye disease, which would include treatment of dry eye flares.

“All currently marketed FDA-approved pharmaceutical treatments for dry eye disease are chronic therapies and are typically used in patients with chronic or persistent dry eye symptoms,” said Dr. Edward Holland, Director of Cornea Services, Cincinnati Eye Institute and Professor of Clinical Ophthalmology, University of Cincinnati. “The vast majority of patients experience episodic dry eye flares that are characterized by acute exacerbations of signs and/or symptoms. An FDA-approved, safe and effective short-term treatment for dry eye disease, including dry eye flares, will represent an important new treatment option for patients and prescribers.”

KPI-121 0.25% utilizes Kala’s proprietary AMPPLIFY Drug Delivery Technology to enhance penetration into target tissues of the eye. In preclinical studies, the AMPPLIFY technology increased delivery of loteprednol etabonate (LE) into ocular tissues more than three-fold compared to current LE products by facilitating penetration through the tear film mucins. The AMPPLIFY technology also underpins INVELTYS™ (loteprednol etabonate ophthalmic suspension) 1%, the first twice-a-day corticosteroid for the treatment of post-operative inflammation and pain following ocular surgery, which was approved by the FDA in August 2018.

The NDA submission for KPI-121 0.25% was supported by data from one Phase 2 and two Phase 3 efficacy and safety trials, STRIDE 1 and STRIDE 2 (STRIDE - Short Term Relief In Dry Eye), studying over 2,000 patients with dry eye disease. Based upon the FDA’s recommendation, Kala also initiated an additional Phase 3 clinical trial, STRIDE 3, in July 2018, evaluating KPI-121 0.25% for the temporary relief of the signs and symptoms of dry eye disease. The Company expects to report top-line results for STRIDE 3 in the fourth quarter of 2019.

About Dry Eye Disease

Dry eye disease is a chronic, episodic, multifactorial disease affecting the tears and ocular surface that can result in tear film instability, inflammation, discomfort, visual disturbance and ocular surface damage. Dry eye disease is estimated to affect approximately 33 million people in the United States, based on an estimated prevalence of 14.5% as described in The Beaver Dam Offspring Study, a major epidemiological study published in 2014 in the American Journal of Ophthalmology. Dry eye disease can have a significant impact on quality of life and can potentially cause long-term damage to the ocular surface. In addition, the vast majority of dry eye patients experience acute exacerbations of their symptoms, which are commonly referred to as flares, at various times throughout the year. These flares can be triggered by numerous factors which cause ocular surface inflammation and impact tear production and/or tear film stability.

About KPI-121 0.25%

Kala is developing KPI-121 0.25% for the temporary relief of the signs and symptoms of dry eye disease utilizing a two-week course of therapy. Dry eye disease is a chronic, episodic, multifactorial disease affecting the tears and ocular surface and can involve tear film instability, inflammation, discomfort, visual disturbance and ocular surface damage. KPI-121 0.25% utilizes Kala's AMPPLIFY™ mucus-penetrating particle (MPP) Drug Delivery Technology to enhance penetration of loteprednol etabonate (LE) into target tissue of the eye. In preclinical studies, the AMPPLIFY Drug Delivery Technology increased delivery of LE into ocular tissues more than three-fold compared to current LE products by facilitating penetration through the tear film mucins. Kala has completed one Phase 2 and two Phase 3 clinical trials, STRIDE 1 and STRIDE 2 (STRIDE - Short Term Relief In Dry Eye), of KPI-121 0.25%. Kala believes that KPI-121 0.25%'s 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, could result in a favorable profile for the management of dry eye flares and other dry eye associated conditions. Kala has filed an NDA with the FDA and has been granted a PDUFA target action date of August 15, 2019. Based upon the FDA’s recommendation, Kala has also initiated an additional Phase 3 clinical trial in July 2018, STRIDE 3, evaluating KPI-121 0.25% for the temporary relief of the signs and symptoms of dry eye disease. Kala believes that it has identified key factors that contributed to the differences observed in the results from STRIDE 2 compared to those of STRIDE 1 and the Phase 2 study, and that changes made to the inclusion/exclusion criteria of STRIDE 3 based on these analyses will improve the probability of success. The Company expects to report top-line results for STRIDE 3 in the fourth quarter of 2019.
