WATERTOWN, Mass.--(BUSINESS WIRE)--Mar. 11, 2019-- Kala Pharmaceuticals, Inc.

“The past year was a landmark period for Kala with the approval and launch of INVELTYS, the first and only twice-daily ocular corticosteroid indicated for the treatment of post-operative inflammation and pain following ocular surgery,” said Mark Iwicki, Chairman, President and Chief Executive Officer of Kala Pharmaceuticals. “Since approval, we completed the buildout of our commercial infrastructure for INVELTYS, including on-boarding a highly experienced ophthalmology specialty sales organization and payer account team. The physician feedback in the first few weeks of launch has been positive, and we are pleased with the uptake in prescription volume along with the progress made in gaining market access.”

Fourth Quarter and Recent Highlights:

INVELTYS Launch Progress: INVELTYS was launched in January 2019 as the first and only twice-daily ocular corticosteroid indicated for the treatment of post-operative inflammation and pain following ocular surgery. The unique combination of safety, efficacy and twice-daily dosing of INVELTYS was developed to address a significant unmet need in this setting, and Kala believes these attributes are being viewed favorably by physicians. In preparation for the launch, Kala hired an experienced specialty ophthalmology sales organization, which is actively calling on customers. In the first few weeks of launch:

• More than 4,000 INVELTYS prescriptions have been filled since launch in January
• INVELTYS has achieved unrestricted market access in approximately one-third of all lives covered by commercial payers
• Medicare Part D contract negotiations are ongoing with most coverage anticipated to begin in 2020; already approximately 20% of INVELTYS prescriptions launch-to-date have been successfully reimbursed through Medicare Part D health plans
• More than 3,000 patients have utilized the co-pay assistance program to have immediate access to INVELTYS

Continued Advancement of KPI-121 0.25% Dry Eye Program: In December 2018, the U.S. Food and Drug Administration (FDA) accepted for review Kala’s New Drug Application (NDA) for KPI-121 0.25%, which if approved could be the first FDA-approved product for the temporary relief of the signs and symptoms of dry eye disease. The FDA has set a PDUFA target action date of August 15, 2019.

• The NDA includes data from one Phase 2 and two Phase 3 efficacy and safety trials studying over 2,000 patients with dry eye disease.
• Based upon the FDA’s recommendation, Kala 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 trials, and that changes made to the inclusion/exclusion criteria of STRIDE 3 based on these analyses will improve the probability of success of the trial.
• STRIDE 3 enrollment continues to progress as planned. The Company expects to receive top-line results for STRIDE 3 in the fourth quarter of 2019.

Fourth Quarter and Full Year 2018 Financial Results

• Cash Position: As of December 31, 2018, Kala had cash of $170.9 million compared to $114.6 million as of December 31, 2017.

  R&D Expenses: For the quarter ended December 31, 2018, research and development (R&D) expenses were $9.2 million compared to $5.9 million for the same period in 2017. The increase in R&D expenses for the fourth quarter was primarily due to the initiation of STRIDE 3 as well as increased headcount and costs in anticipation of the INVELTYS launch.
  
  R&D expenses for the full year ended December 31, 2018 were $29.3 million compared to $29.0 million for the year ended December 31, 2017. External costs associated with STRIDE 1 and 2 decreased during 2018 and were offset by costs associated with STRIDE 3, as well as an increase in headcount and costs in anticipation of the INVELTYS launch, stock-based compensation expense, and the PDUFA fee paid in connection with our NDA for KPI-121 0.25%.
  
  Non-GAAP R&D expenses were $8.6 million for the quarter ended December 31, 2018 compared to $5.3 million for the same period in 2017.

SG&A expenses for the full year ended December 31, 2018 were $35.4 million compared to $10.9 million for the year ended December 31, 2017.
  
  The increases in SG&A expenses for the quarter ended December 31, 2018 were primarily due to costs associated with hiring additional personnel, building our commercial organization and external costs in advance of the launch of INVELTYS in January 2019, and an increase in our facility costs due to the commencement of the lease of our new corporate headquarters.
  
  For the year ended December 31, 2018 compared to the same period in 2017, the increase in costs was a result of stock compensation expense associated with stock options granted during the year and external costs associated with operating as a public company for a full year, in addition to the items which resulted in an increase in SG&A expenses for the quarter ended December 31, 2018 compared to the same period in 2017.
  
  Non-GAAP SG&A expenses were $12.7 million for the quarter ended December 31, 2018 compared to $4.3 million for the same period in 2017.
