Press Release

BEDFORD, Mass.--(BUSINESS WIRE)--Nov. 24, 2015-- Ocular Therapeutix, Inc. (NASDAQ:OCUL), a biopharmaceutical company focused on the development and commercialization of innovative therapies for diseases and conditions of the eye, announced today enrollment of the first patients in a second Phase 3 clinical trial to evaluate the safety and efficacy of DEXTENZA™ (sustained release dexamethasone), 0.4mg Intracanalicular Depot for the treatment of allergic conjunctivitis. DEXTENZA is a product candidate administered by a physician as a bioresorbable intracanalicular depot and designed for drug release to the ocular surface for up 30 days, which would far surpass the duration of the current standard of care for ocular allergy treatment which is one day.

This prospective, U.S.-based multicenter, 1:1 randomized, double-masked, vehicle-controlled trial is enrolling patients who exhibit chronic signs and symptoms of allergic conjunctivitis. This is the second Phase 3 trial that will evaluate DEXTENZA versus a placebo vehicle punctum plug using Ophthalmic Research Associate’s modified Conjunctival Allergen Challenge (Ora-CAC®) Model (Ora, Inc., Andover, MA) which accommodates for the longer therapeutic effect of a seasonal one-time administered drug product. The trial is designed to assess the effect of DEXTENZA compared with placebo on allergic reactions using four series of successive allergen challenges over a 30-day period. DEXTENZA or placebo will be administered 48 to 72 hours after final confirmatory exposure to the allergen. The primary endpoint to be evaluated is ocular itching at day 7 following insertion.

“We are pleased to advance the DEXTENZA platform in allergic conjunctivitis, with the goal of providing patients with one-time, seasonal therapy that is preservative-free,” said Amar Sawhney, Ph.D., President, Chief Executive Officer and Chairman of Ocular Therapeutix, Inc. “For the first time, DEXTENZA offers the potential for full-season relief to the patient, as a product candidate designed to both treat ocular itching for 4 weeks and offer prophylaxis against allergic conjunctivitis.” Sawhney continued, “The start of another Phase 3 clinical trial for DEXTENZA demonstrates our commitment to applying our proprietary, hydrogel platform to additional indications where patients can benefit from sustained-release therapies. In addition to allergic conjunctivitis, the Company submitted a New Drug Application (NDA) to the FDA for a post-surgical ocular pain indication in October 2015, and an exploratory Phase 2 clinical trial in inflammatory dry eye is expected to read out with topline results before the end of the year.”

Ocular Therapeutix reported topline results of its first Phase 3 allergic conjunctivitis clinical trial in October 2015. If the Company meets the primary efficacy endpoint for ocular itching in the second Phase 3 trial and subject to the approval of the NDA submitted for DEXTENZA for the treatment of post-surgical ocular pain, the Company expects to submit an NDA supplement to the FDA for ocular itching associated with allergic conjunctivitis. Many ocular drugs used to treat allergic conjunctivitis have been approved by the FDA solely for ocular itching. Under a revised protocol, the Company’s only primary endpoint in the second Phase 3 trial is for ocular itching.

About Allergic Conjunctivitis
Allergic conjunctivitis is an inflammatory disease of the conjunctiva resulting primarily from a reaction to allergy-causing substances such as pollen or pet dander. The primary symptom of this inflammation is acute ocular itching and the primary sign is conjunctival redness. Allergic conjunctivitis ranges in clinical severity from relatively mild, common forms to more severe forms that can cause impaired vision. According to a study on the management of seasonal allergic conjunctivitis published in 2012 in the peer-reviewed journal Acta Ophthalmologica, allergic conjunctivitis affects 15% to 40% of the U.S. population. For patients with chronic or more severe forms of allergic conjunctivitis, antihistamines and mast cell stabilizers are often not sufficient to treat their signs and symptoms. Many ocular allergy sufferers are not responsive to the conventional dual-acting antihistamine/mast cell stabilizers. These refractory patients are frequently treated with topical corticosteroids administered by eye drops.
