WALTHAM, Mass.--(BUSINESS WIRE)--Kala Pharmaceuticals, Inc. (NASDAQ:KALA) today announced that it has submitted a New Drug Application (NDA) to the United States Food and Drug Administration (FDA) for INVELTYSTM (KPI-121 1%), a topical twice-a-day product candidate for the treatment of inflammation and pain in patients who have undergone ocular surgery. If approved, Kala expects INVELTYS would be the first twice-daily ocular corticosteroid indicated for the treatment of post-operative ocular inflammation and pain. The brand name for KPI-121 1%, INVELTYS, has been conditionally approved by the FDA.
INVELTYS utilizes Kala’s proprietary Mucus Penetrating Particle (MPP) technology. MPPs are selectively-sized nanoparticles with proprietary coatings that significantly enhance drug penetration and distribution in ocular tissues. In pre-clinical studies, MPPs increased delivery into ocular tissues more than three-fold by facilitating penetration through the tear film mucus.
“INVELTYS administered twice-a-day to patients following cataract surgery demonstrated statistically significant resolution of both inflammation and pain in each of two Phase 3 clinical trials,” said Kim Brazzell, Ph.D., Chief Medical Officer of Kala Pharmaceuticals. “Based on these results, as well as its safety profile and twice-daily dosing, we believe that INVELTYS would be a valuable treatment option for doctors and patients.”
The NDA filing is supported by positive data from two Phase 3 trials. The first Phase 3 clinical trial was designed to evaluate INVELTYS administered twice-a-day and KPI-121 0.25% administered four times a day for 14 days following cataract surgery. Statistical significance was achieved for the primary efficacy endpoints of complete resolution of inflammation at day 8 maintained through day 15 with no need for rescue medication compared to placebo and complete resolution of pain at day 8 maintained through day 15 with no need for rescue medications compared to placebo with both INVELTYS and KPI-121 0.25%. In May 2017, Kala announced topline results from the second, confirmatory Phase 3 clinical trial with INVELTYS. Compared to placebo, administration of INVELTYS twice-a-day for 14 days achieved statistical significance for both primary efficacy endpoints of complete resolution of inflammation at day 8 maintained through day 15 with no need for rescue medication compared to placebo and complete resolution of pain at day 8 maintained through day 15 with no need for rescue medications and all secondary endpoints. INVELTYS was found to be well tolerated with no treatment-related serious adverse events observed during the course of either trial.
“The filing of the NDA for INVELTYS marks a major milestone for Kala in advancing our mission of developing treatments for eye conditions using our MPP technology,” said Mark Iwicki, Chairman and Chief Executive Officer of Kala Pharmaceuticals. “We believe that our MPP technology has the potential to not only improve the post-operative care of patients undergoing ocular surgery, but also help advance care in other ophthalmic indications such as dry eye disease using our KPI-121 0.25% product candidate. 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.”
About Post-Operative Inflammation and Pain
Ocular inflammation and pain are common complications following ocular surgery. According to Marketscope, in 2016 there were 7.7 million ocular surgeries in the United States, which is projected to grow to up to 9.4 million in 2021. More than half of the ocular surgeries performed in the U.S. are cataract surgeries. Tissue damage caused by ocular surgery leads to the production of prostaglandins, lipids that aid in recovery at the site of an injury, and an increase in blood flow to the affected area, both of which contribute to inflammation. The standard of care for post-operative inflammation and pain includes anti-inflammatory drugs such as corticosteroids, which improve patient comfort and accelerate recovery through disruption of the inflammatory cascade. The current four-times-a-day dosing regimen for corticosteroid treatment can be burdensome for patients as they are taking multiple eye drop products following surgery, and is believed to reduce patient compliance. There are no twice-daily ocular corticosteroid products currently approved in the U.S. for the treatment of post-operative inflammation and pain.
About INVELTYSTM (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 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 statistiscal 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.
