Press Release

BEDFORD, Mass.--(BUSINESS WIRE)--Oct. 14, 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, today announced the enrollment of the first patients in a third Phase 3 clinical trial for DEXTENZA^TM (sustained release dexamethasone) 0.4mg Intracanalicular Depot, for the treatment of post-surgical ocular inflammation and pain.

Based on the results of the Company’s two previously completed Phase 3 clinical trials and following a Pre-NDA Clinical meeting with the U.S. Food and Drug Administration (FDA) in April 2015, the Company recently submitted a New Drug Application (NDA) to the FDA for DEXTENZA^TM (sustained release dexamethasone) 0.4mg Intracanalicular Depot, for the treatment of ocular pain following ophthalmic surgery. The Company intends to submit a supplement to the NDA for the treatment of post-surgical inflammation as part of its label expansion strategy for DEXTENZA if it obtains favorable results from this third Phase 3 clinical trial and subject to receiving approval of the pain indication pursuant to the initial NDA.

“This is an important step for Ocular as we continue to execute on our label expansion strategy for DEXTENZA and we look forward to offering patients this innovative alternative to steroid eye drop therapy,” said Amar Sawhney, Ph.D., President, Chief Executive Officer and Chairman.

This prospective, multicenter, randomized, parallel-arm, double-masked, vehicle-controlled study is enrolling 436 patients undergoing clear corneal cataract surgery at 20 sites throughout the United States. Following surgery, patients will be randomized to either DEXTENZA or a placebo vehicle. Primary endpoints are absence of anterior chamber cells at day 14 and reduction of pain at day 8. Based on the learnings from the two previously conducted Phase 3 clinical trials and following a Pre-NDA Clinical meeting with the FDA, the Company has designed this trial to include key modifications, such as:

• 1:1 patient randomization of treatment and placebo groups instead of a 2:1 randomization;
• Exclusion of patients who are being treated with high dosage levels of oral nonsteroidal anti-inflammatory drugs, or NSAIDs; and
• Improvement of the training and guidance to the on-site clinical investigators regarding adherence to study protocols, including the appropriate use of rescue medications.

The Company anticipates that top-line efficacy results from this trial will be available in late 2016.

About DEXTENZA^TM

DEXTENZA (sustained release dexamethasone) 0.4 mg Intracanalicular Depot is a product candidate placed through the punctum, a natural opening in the eyelid, into the canaliculus and delivers dexamethasone to the ocular surface for four weeks. Following treatment, DEXTENZA resorbs and exits the nasolacrimal system without need for removal. To capitalize on the broader opportunity for the sustained delivery of corticosteroids to the front of the eye, the Company is pursuing multiple indications for DEXTENZA.

Earlier this year, Ocular Therapeutix announced results from its two completed Phase 3 clinical trials of DEXTENZA for the treatment of ocular inflammation and pain following ophthalmic surgery. The Company recently submitted an NDA to the FDA for ocular pain following ophthalmic surgery and has initiated the third Phase 3 clinical trial for ocular inflammation and pain. The Company recently completed enrollment in a Phase 3 clinical trial of DEXTENZA for the treatment of allergic conjunctivitis and expects to report topline efficacy data from this trial in the fourth quarter of 2015. The Company has also completed patient enrollment in an exploratory Phase 2 clinical trial of DEXTENZA for the treatment of inflammatory dry eye and expects to report topline efficacy data from this trial in the fourth quarter of 2015.

About Ocular Inflammation and Pain Following Ophthalmic Surgery

Ocular pain and inflammation are common side effects following ophthalmic surgery. Physicians prescribe anti-inflammatory drugs, such as corticosteroids, as the standard of care. If left untreated, inflammation of the eye may result in further ocular complications, including scarring and vision loss. Approximately 5.3 million ocular surgeries were performed in the United States in 2014.
