Ocular Therapeutix™ Announces Notification of FDA Acceptance of Supplemental New Drug Submission for DEXTENZA® (dexamethasone ophthalmic insert) for the Treatment of Ocular Inflammation Following Ophthalmic Surgery

April 2, 2019

BEDFORD, Mass.--(BUSINESS WIRE)--Apr 2, 2019--Ocular Therapeutix™, Inc. (NASDAQ: OCUL), a biopharmaceutical company focused on the formulation, development, and commercialization of innovative therapies for diseases and conditions of the eye, today announced the U.S. Food and Drug Administrations (FDA) has accepted for filing the supplemental New Drug Application (sNDA) for DEXTENZA ® (dexamethasone ophthalmic insert) to include the treatment of ocular inflammation following ophthalmic surgery in its label. The notice of acceptance confirms the FDA has completed its initial review of the filing and has determined that the sNDA is sufficiently complete to permit formal review. The FDA has set a Prescription Drug User Fee Act (PDUFA) target action date of November 10, 2019 for its review of the sNDA.

DEXTENZA is the first FDA-approved intracanalicular insert delivering dexamethasone to treat post-surgical ocular pain for up to 30 days with a single administration. DEXTENZA received FDA approval in November 2018 for the treatment of ocular pain following ophthalmic surgery. DEXTENZA is a resorbable, preservative-free ophthalmic insert that is placed in the lower lacrimal punctum and into the canaliculus of the eye.

The sNDA application to include inflammation [following ophthalmic surgery] is supported by the two Phase 3 clinical trials used to obtain the pain approval and safety and efficacy data from a third prospective, multicenter, randomized, controlled Phase 3 clinical trial of DEXTENZA (n=438) in cataract surgery patients that demonstrated statistical significance compared to the vehicle control for the endpoints of absence of ocular pain (p<0.0001) and absence of inflammation (p<0.0001). The ocular safety profile was similar to that demonstrated in the two prior Phase 3 clinical trials. Data from the third Phase 3 clinical trial was recently published in the Journal of Cataract & Refractive Surgery (JCRS) in February 2019.

Current DEXTENZA Indication and Important Safety Information

DEXTENZA (dexamethasone ophthalmic insert) is a corticosteroid indicated for the treatment of ocular pain following ophthalmic surgery.

CONTRAINDICATIONS
DEXTENZA is contraindicated in patients with active corneal, conjunctival or canalicular infections, including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella; mycobacterial infections; fungal diseases of the eye, and dacryocystitis.

WARNINGS AND PRECAUTIONS
Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision. Steroids should be used with caution in the presence of glaucoma. Intraocular pressure should be monitored during treatment.

Corticosteroids may suppress the host response and thus increase the hazard for secondary ocular infections. In acute purulent conditions, steroids may mask infection and enhance existing infection.

Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex).

Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use. Fungal culture should be taken when appropriate.

Use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation.

ADVERSE REACTIONS
The most common ocular adverse reactions that occurred in subjects treated with DEXTENZA were: anterior chamber inflammation including iritis and iridocyclitis (9%); increased intraocular pressure (5%); reduced visual acuity (2%); eye pain (1%); cystoid macular edema (1%); corneal edema (1%); and conjunctival hyperemia (1%). The most common non-ocular adverse event was headache (1%).
