RELEASE DETAILS

Completed Initial Public Offering Raising $103.5 million in gross proceeds

Submitted New Drug Application to U.S. Food and Drug Administration for INVELTYS™ (KPI-121 1%)

WALTHAM, Mass.--(BUSINESS WIRE)--Nov. 7, 2017-- Kala Pharmaceuticals, Inc. (NASDAQ:KALA), a biopharmaceutical company focused on the development and commercialization of product candidates using its proprietary mucus-penetrating particle (MPP) technology, today reported financial results for the third quarter and nine months ended September 30, 2017 and provided an update on business progress.

“During the third quarter of 2017, Kala strengthened its financial position by closing a successful initial public offering resulting in gross proceeds of $103.5 million, which we estimate will allow us to complete clinical development, and prepare for the commercialization of INVELTYS™ (KPI-121 1%) and KPI-121 0.25%,” said Mark Iwicki, Chairman and Chief Executive Officer of Kala Pharmaceuticals. “Based on the positive results of two Phase 3 clinical trials of INVELTYS for the treatment of inflammation and pain in patients who have undergone cataract surgery, we submitted a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in October. We expect to receive topline results from the Phase 3 clinical program for KPI-121 0.25% in patients with dry eye disease by the end of 2017.”

Q3 and Recent Corporate Highlights

• Completed initial public offering in July of 6,900,000 shares of common stock, including the underwriters’ exercise in full of their option to purchase an additional 900,000 shares, at the public offering price of $15.00 per share. The exercise of the underwriters’ option brought the amount of gross proceeds raised in the offering to approximately $103.5 million, or $94.1 million in net proceeds after underwriting discounts, commissions and expenses of the offering.
• Submitted New Drug Application (NDA) for INVELTYS in October for the treatment of inflammation and pain in patients who have undergone ocular surgery. The NDA submission is supported by positive data from two Phase 3 trials. If approved, Kala expects INVELTYS would be the first twice-daily ocular corticosteroid indicated for the treatment of post-operative ocular inflammation and pain.
• Strengthened Board of Directors in October with the appointment of Mr. Andrew I. Koven, who has served as President and Chief Business Officer at Aralez Pharmaceuticals Inc., since 2016 and held the same position in 2015 at POZEN Inc., where he was instrumental in negotiating a merger with Tribute Pharmaceuticals Canada Inc. to create Aralez Pharmaceuticals. Prior to joining POZEN, Mr. Koven was Chief Administrative Officer, General Counsel and Corporate Secretary at Auxilium Pharmaceuticals Inc.

Upcoming Milestones

• Top-line results from the Phase 3 clinical program for KPI-121 0.25% in patients with dry eye disease are expected by the end of 2017. KPI-121 0.25% is our product candidate for the temporary relief of the signs and symptoms of dry eye disease utilizing a two-week course of therapy. Assuming positive results from these trials, the Company anticipates submitting an NDA in the first half of 2018. If approved, KPI-121 0.25% could be the first FDA-approved product for the short-term treatment of dry eye disease.

Third Quarter 2017 Financial Results

• Cash Position: As of September 30, 2017, Kala had cash of $122.0 million compared to $45.5 million as of December 31, 2016. Cash as of December 31, 2016 did not include net proceeds of approximately $94.1 million from the Company’s initial public offering in July 2017 or the proceeds from the draw of the Company’s debt facility of $10.0 million in September 2017. Kala expects that its existing cash on hand will enable it to fund operations through the second quarter of 2019.
• R&D Expenses: For the quarter ended September 30, 2017, research and development expenses were $7.0 million compared to $8.3 million for the same period in 2016. The decrease in research and development expenses is primarily due to a decrease in costs associated with our two Phase 3 clinical trials of KPI-121 0.25% for the treatment of dry eye disease and the completion of our Phase 3 clinical trial of INVELTYS for the treatment of inflammation and pain following ocular surgery in the first half of 2017.
• G&A Expenses: General and administrative expenses for the quarter ended September 30, 2017 were $2.5 million compared to $1.5 million for the same period in 2016. The increase in G&A expenses is primarily attributable to an increase in personnel costs and professional fees associated with operating as a public company.
• Operating Loss: Loss from operations for the quarter ended September 30, 2017 was $9.5 million compared to $9.7 million for the same period in 2016.
• Net Loss: Net loss was $10.2 million, or $0.56 per share, for the three months ended September 30, 2017, compared to a net loss of $9.7 million or $8.18 per share, for the same period in 2016.

About INVELTYS™ (KPI-121 1%)
INVELTYS™ (KPI-121 1%) is a twice-a-day corticosteroid for the treatment of inflammation and pain following ocular surgery. INVELTYS utilizes Kala’s proprietary mucus-penetrating particle (MPP) technology to enhance penetration into target tissues of the eye. In pre-clinical studies, MPP technology increased delivery of a corticosteroid into ocular tissues more than three-fold by facilitating penetration through the tear film mucus. INVELTYS has successfully completed two Phase 3 clinical trials and achieved statistical significance for both primary efficacy endpoints in both trials. Kala believes INVELTYS has a favorable treatment profile compared to the standard of care for the treatment of inflammation and pain following ocular surgery, due to its twice-a-day dosing regimen and rapid onset of relief. In each of these trials, INVELTYS was well tolerated with no treatment-related serious adverse events observed.

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 administered four times a day. 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. KPI-121 0.25% utilizes Kala’s MPP technology to enhance penetration into target tissue of the eye. In preclinical studies, MPP technology increased delivery of a corticosteroid into ocular tissues more than three-fold by facilitating penetration through the tear film mucus. Kala believes that KPI-121 0.25%’s broad mechanism of action, rapid onset of relief of both signs and symptoms, favorable tolerability profile and 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 that would benefit from temporary relief of dry eye signs and symptoms. Following the achievement of successful results in a Phase 2 trial, Kala is currently evaluating KPI-121 0.25% in two Phase 3 clinical trials in patients with dry eye disease. If approved, KPI-121 0.25% could be the first FDA-approved product for the short-term treatment of dry eye disease.
