FDA Approves Inveltys

FDA Approves Inveltys (loteprednol etabonate) for Post-Operative Inflammation and Pain Following Ocular Surgery

WALTHAM, Mass.--(BUSINESS WIRE)--Aug. 23, 2018-- Kala Pharmaceuticals, Inc. (NASDAQ:KALA), a biopharmaceutical company focused on the development and commercialization of therapeutics using its proprietary mucus-penetrating particle (MPP) technology, today announced that the U.S. Food and Drug Administration (FDA) has approved Inveltys (loteprednol etabonate ophthalmic suspension) 1% for the treatment of post-operative inflammation and pain following ocular surgery. Inveltys is the first twice-daily (BID) ocular corticosteroid approved for this indication.

“The FDA approval of Inveltys is a tremendous milestone for Kala,” said Kim Brazzell, Ph.D., Chief Medical Officer of Kala Pharmaceuticals. “Approximately 8 million patients undergo ocular surgeries each year. The approval of Inveltys offers patients and their eye care professionals the first and only BID ocular corticosteroid therapy that has been shown in clinical trials to be clinically effective while maintaining a proven safety profile, which may improve compliance and prove less burdensome for patients. We believe Inveltys will be an important addition to eye care professionals’ treatment armamentarium.”

All other ocular steroids are only approved for four-times-a-day dosing. This more frequent dosing requirement can lead to issues for both doctors and patients. Corticosteroids are the foundation of therapy for post-ocular surgery care, with the key goal of controlling inflammation and pain which is caused by surgical trauma to the eye. The use of ocular steroids post-surgery is to achieve a rapid reduction of inflammation and to promote healing of the eye. Therefore, ensuring close adherence to the steroid regimen is a critical factor for physicians in the post-surgery care of the patient and eventual overall success of the procedure.

“Today's approval of Inveltys is welcome news for the eye care community as it provides a clear advancement in the treatment for inflammation and pain following ocular surgery. Having access to a BID corticosteroid in a novel nanoparticle formulation with proven safety and efficacy will make a positive impact on the management of my post-operative patients,” said Terry Kim, M.D., Professor of Ophthalmology and Chief, Cornea and External Disease Division, Duke University Eye Center.

“On behalf of the Kala team, I want to thank the many patients and clinicians who participated in our clinical trials. With this approval, our ongoing commercialization preparations now advance to the next phase where we plan to hire a specialty sales force that will focus on eye care professionals in the United States. We expect to launch Inveltys in the beginning of 2019,” said Mark Iwicki, Chairman, President and Chief Executive Officer of Kala Pharmaceuticals.

Inveltys Important Safety Information

Inveltys, 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.

A prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision. If this product is used for 10 days or longer, IOP should be monitored.

Use of corticosteroids may result in posterior subcapsular cataract formation.

Use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids. The initial prescription and 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 suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions, steroids 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 steroids 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 steroid application. Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use.

In clinical trials, the most common adverse drug reactions were eye pain (1%) and posterior capsular opacification (1%). These reactions may have been the consequence of the surgical procedure.

About Post-Operative Inflammation and Pain

Ocular inflammation and pain are common complications following ocular surgery. According to Marketscope, in 2017 there were approximately 8 million ocular surgeries in the U.S., which is projected to grow to up to approximately 10 million in 2022. 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 other twice-daily ocular corticosteroid products currently approved in the U.S. for the treatment of post-operative inflammation and pain.

About Inveltys

Inveltys (loteprednol etabonate ophthalmic suspension) 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 preclinical studies, MPP technology increased delivery of LE into ocular tissues compared to current LE products. Inveltys successfully completed two Phase 3 clinical trials and achieved statistical significance for both primary efficacy endpoints in both trials. In each of these trials, Inveltys was well tolerated with no treatment-related serious adverse events observed. Inveltys was approved by the FDA on August 22, 2018. Kala believes Inveltys has a favorable profile for the treatment of inflammation and pain following ocular surgery, due to its twice-a-day dosing regimen.
