Announced Positive Interim Data from the U.S.-based Phase 1 Clinical Trial of OTX-TKI for the Treatment of Wet AMD at the American Academy of Ophthalmology (AAO) 2022 Annual Meeting

Initiation of OTX-TKI Phase 1 Clinical Trial for the treatment of Diabetic Retinopathy Planned for Q1 of 2023 and Phase 2/3 Clinical Trial for the treatment of Wet AMD Planned for Q3 of 2023

DEXTENZA® (dexamethasone ophthalmic insert) 0.4 mg Recorded Quarterly Net Product Revenue of $11.9 Million

Revised DEXTENZA Annual Net Product Revenue Guidance for 2022 to be between $48 to $52 million, Representing Annual Growth of Approximately 10% to 20%

Conference Call to Discuss Third Quarter Results to be Held at 4:30 p.m. ET

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 reported financial results for the quarter ended September 30, 2022, and provided updates on its ophthalmology pipeline.

“We presented arguably the most important clinical data in the Company’s history at this year’s AAO meeting” commented Antony Mattessich, President and CEO. “In the 7-month data from our U.S.-based Phase 1 clinical trial of a 600 µg, single implant OTX-TKI for the treatment of controlled wet AMD, 80% and 73% of subjects were rescue-free up to 6 and 7 months, respectively. In addition to our goal of moving OTX-TKI into a Phase 2/3 trial for the treatment of wet AMD in Q3 of 2023, we also plan to initiate a Phase 1 trial for the treatment of diabetic retinopathy (DR) in Q1 of 2023. Pending good results, and subject to a follow-up meeting with the FDA, we believe we could be in position to initiate our first Phase 3 trial of OTX-TKI for the treatment of DR in Q1 of 2024. On the commercial front, DEXTENZA achieved net revenue of $11.9 million for the quarter despite the continued staffing challenges that we have observed at our ASC and HOPD customers that hindered their ability to operate at full capacity. We believe these challenges are transient in nature and that recent staffing of our sales force at targeted levels and bringing new sales territories online should have a near and long term positive impact on DEXTENZA sales.”

Business Updates

OTX-TKI (axitinib intravitreal implant) for the potential treatment of wet AMD, diabetic retinopathy and other retinal diseases.

• Presented positive interim 7-month data from U.S.-based Phase 1 trial of OTX-TKI for the treatment of Wet AMD at the AAO 2022 Annual Meeting. Data was presented using a data cut-off date of August 24, 2022.
  • Interim data showed a single OTX-TKI implant was generally well tolerated with no drug-related ocular or systemic serious adverse events (SAEs). There were no reported adverse events such as elevated IOP, retinal detachment, retinal vasculitis, or implant migration into the anterior chamber observed in the OTX-TKI arm. There was one SAE of acute endophthalmitis in the OTX-TKI arm which occurred following a mandated aflibercept injection at Month 1.
  • Subjects treated with a single OTX-TKI implant demonstrated stable and sustained best corrected visual acuity (BCVA) (mean change from baseline of -1.3 letters) and central subfield foveal thickness (CSFT) (mean change from baseline of +9.2 µm) at 7 months, which was comparable with the aflibercept arm dosed every 8 weeks (mean change from BVCA baseline of -1 letter; mean change from CSFT baseline of +0.4 µm).
  • 80% of subjects in the OTX-TKI arm were rescue-free up to 6 months and 73% of subjects in the OTX-TKI arm were rescue-free up to 7 months.
  • The Company intends to present 10-month data at the upcoming Angiogenesis, Exudation, and Degeneration 2023 Meeting at 8:10 am on Saturday, February 11^th, 2023 and plans to follow subjects at least until their respective one-year anniversaries of initial dosing, in accordance with the clinical trial protocol.
  • The Company plans to meet with the FDA in early 2023 to discuss potential future clinical trial requirements with the goal of initiating a Phase 2/3 clinical trial for the treatment of wet AMD in Q3 of 2023.
• The Company intends to initiate a U.S.-based Phase 1 clinical trial for the treatment of DR in Q1 of 2023.
  • The US Phase 1 trial is planned to be conducted under an existing eIND across approximately 10 sites and is designed to include approximately 20 patients randomized to either a 600 µg OTX-TKI single implant containing axitinib or sham control.
  • Pending good data results from the Phase 1, and subject to a follow-up meeting with the FDA, the Company believes it could be well positioned to initiate its first Phase 3 pivotal trial for the treatment of DR in Q1 of 2024.

OTX-TIC (travoprost intracameral implant) for the treatment of patients with primary open-angle glaucoma or ocular hypertension.

• The Company continues to actively enroll its U.S.-based Phase 2 prospective, multi-center, randomized, controlled clinical trial evaluating the safety, tolerability, and efficacy of OTX-TIC for the treatment of patients with primary open-angle glaucoma or ocular hypertension.
• The Company has designed the Phase 2 trial to evaluate whether OTX-TIC can cause a clinically meaningful decrease in intraocular pressure while preserving endothelial cell health, enabling repeat dosing.
• The Company plans to provide a topline data release in Q4 of 2023.

Dry Eye Programs moving forward in a measured manner with a collaborative study of OTX-DED (dexamethasone intracanalicular insert) for the short-term treatment of the signs and symptoms of dry eye disease.

• The Company intends to initiate a collaborative clinical trial in the first half of 2023 to evaluate the performance of OTX-DED versus fast-dissolving collagen plugs and no inserts at all. Specifically, the Company plans to conduct this trial to explain the magnitude of the placebo effect seen in both the OTX-DED and the OTX-CSI (cyclosporine intracanalicular insert for the chronic treatment of dry eye disease) Phase 2 trials in which the vehicle hydrogel placebo insert remained in the canaliculus longer than anticipated, performing more like an active comparator than a placebo comparator.
• The Company plans to use the results of the collaborative study to inform the next steps for both OTX-DED and OTX-CSI.

DEXTENZA (dexamethasone ophthalmic insert) 0.4mg is FDA approved for the treatment of ocular inflammation and pain following ophthalmic surgery and ocular itching associated with allergic conjunctivitis.

• Net product revenue of DEXTENZA for the quarter was $11.9 million, in line with the third quarter of 2021 and down approximately 2% sequentially quarter-over-quarter.
• In-market purchases were over 26,000 billable units for the quarter, down approximately 2% quarter-over-quarter as the Company believes many end customers, primarily ASCs, continued to operate below capacity due to staffing challenges.
• In light of this performance, the Company is revising its guidance to $48 to $52 million in net product revenue for 2022.
• The Company presented multiple posters on the real-world safety, demographic and clinical characteristics of DEXTENZA using the Academy’s IRIS® Registry at the AAO 2022 Annual Meeting.
• On November 1, 2022, the Centers for Medicare and Medicaid Services (CMS) issued the calendar year 2023 hospital outpatient prospective payment system (OPPS) rule, confirming that DEXTENZA, as anticipated, will be separately payable in ambulatory surgery centers under the non-opioid supply provision for CY 2023.

Third Quarter Ended September 30, 2022 Financial Results

Net revenue, which includes both gross product revenue net of discounts, rebates, and returns, which the Company refers to as total net product revenue, and collaboration revenue was $12.0 million for the third quarter of 2022 and represented an approximately 2% decrease over the same period in 2021. DEXTENZA net product revenue was $11.9 million for the third quarter of 2022, flat to the comparable quarter of 2021 and down approximately 2% on a sequential quarterly basis. Net revenue in the third quarter of 2022 also included $0.1 million in collaboration revenue associated with the Company’s work with AffaMed. Net product revenue in the third quarter of 2021, included $0.3 million attributable to sales of ReSure Sealant.

Research and development expenses for the third quarter of 2022 were $13.7 million versus $12.7 million for the comparable period in 2021 driven primarily by an increase in personnel and a higher level of preclinical development activity.

Selling and marketing expenses in the third quarter of 2022 were $10.2 million as compared to $9.6 million for the comparable quarter of 2021, reflecting primarily an increase in field force personnel.

General and administrative expenses were $8.5 million for the third quarter of 2022 versus $8.1 million in the comparable quarter of 2021, primarily due to an increase in personnel related costs, including stock-based compensation.

The Company reported a net loss for the third quarter of 2022 of $(24.2) million, or a loss of $(0.31) per share on a basic and diluted basis, compared to net income of $2.7 million, or net income of $0.03 per share on a basic basis and a loss of $(0.23) per share on a diluted basis for the same period in 2021. Net loss in the third quarter of 2022 included a $1.1 million non-cash item attributable to an increase in the fair value of the derivative liability associated with the Company’s convertible notes, as the price of its common stock increased during the quarter. Non-cash charges for stock-based compensation and depreciation and amortization were $4.7 million in the third quarter of 2022 versus $4.4 million for the same quarter in 2021.

As of November 4, 2022, the Company had 77.0 million shares outstanding.

2022 Financial Guidance

• Total net product revenue in 2022 is expected to be in the range of $48 to $52 million, representing growth of between 10% to 20% over 2021. The growth is anticipated to be driven by sales of DEXTENZA for the treatment of post-surgical inflammation and pain.
• As of September 30, 2022, the Company had $121.0 million in cash and cash equivalents versus $134.5 million at June 30, 2022. Based on current plans and related estimates of anticipated cash inflows from DEXTENZA and anticipated cash outflows from operating expenses, the Company believes that its existing cash and cash equivalents are sufficient to enable the Company to fund planned operating expenses, debt service obligations and capital expenditure requirements through 2023. This cash guidance is subject to a number of assumptions including the impacts from the ongoing COVID-19 pandemic; the revenues, expenses and reimbursement associated with DEXTENZA; and the pace of research and clinical development programs, among other aspects of the business.
