Item 8.01. Other Events.

On September 24, 2019, Ocular Therapeutix, Inc. (the “Company”) announced that it had dosed the first patients in its Phase 3 clinical trial of DEXTENZA® for the treatment of symptoms of allergic conjunctivitis (“AC”).

The Phase 3 clinical trial is a U.S.-based, multi-center, 1:1 randomized, double-masked, placebo-controlled trial that intends to enroll approximately 80 subjects, testing the safety and efficacy of DEXTENZA (dexamethasone ophthalmic insert) 0.4 mg versus a placebo vehicle punctum plug using the Ophthalmic Research Associates’ modified Conjunctival Allergen Challenge (Ora-Cac®) Model for the treatment of ocular itching associated with AC. The trial is designed to assess the effect of DEXTENZA compared with a placebo on allergic reactions using a series of successive allergen challenges over a 30-day period. The primary efficacy endpoint being evaluated in the study is ocular itching following insertion of DEXTENZA at multiple time points during the 30-day period. DEXTENZA is administered by a physician as a bioresorbable intracanalicular insert and designed for drug release to the ocular surface for up to 30 days.

This trial represents the third Phase 3 clinical trial in AC conducted by the Company and, if successful, the Company plans to submit a supplemental New Drug Application to the U.S. Food and Drug Administration (“FDA”) for ocular itching associated with AC. Topline data from this trial are anticipated in the first half of 2020.

About DEXTENZA® (dexamethasone ophthalmic insert) 0.4mg

DEXTENZA is an FDA-approved corticosteroid indicated for the treatment of ocular inflammation and pain following ophthalmic surgery. DEXTENZA is inserted into the lower lacrimal punctum into the canaliculus by the physician following ophthalmic surgery. A single DEXTENZA releases a 0.4mg dose of dexamethasone for up to 30 days following insertion. DEXTENZA is preservative free, resorbable and does not require removal. Saline irrigation or manual expression can be performed to remove the insert, if necessary.

DEXTENZA is contraindicated in patients with active corneal, conjunctival or canalicular infections.  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 the course of the treatment. Corticosteroids may suppress the host response to, and increase the hazard for and severity of, secondary bacterial, viral, or fungal infections. The use of steroids after cataract surgery may delay wound healing and increase the incidence of bleb formation.

The most commonly reported ocular adverse reactions that occurred in patients treated with DEXTENZA were anterior chamber inflammation including iritis and iridocyclitis (10%) and elevations in intraocular pressure (6%). The most common non-ocular adverse reaction was headache (1%).
