BEDFORD, Mass., Jan. 06, 2023 (GLOBE NEWSWIRE) — 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 provided a corporate update on the progress of its key programs.

“2022 marked a year in which Ocular made good progress against its corporate mission of becoming a mid-tier strategic within ophthalmology,” said Antony Mattessich, President and CEO. “DEXTENZA, despite challenging market conditions, has established itself as a material and important product and demonstrated renewed growth in the fourth quarter of 2022.”

Mr. Mattessich continued: “The highlight of our year at Ocular was further development within our pipeline. At AAO in September, we presented impressive interim 6- and 7-month data from our U.S.-based Phase 1 clinical trial of OTX-TKI for the treatment of wet AMD. We believe the data further strengthen our ongoing development in wet AMD and supports proof of concept for OTX-TKI’s potential in the treatment of VEGF-mediated vascular retinal diseases, including diabetic retinopathy. Both wet AMD and diabetic retinopathy represent large markets where durability could significantly reduce the burden of anti-VEGF injections and improve real-world outcomes for patients. With that in mind, we initiated a Phase 1 clinical trial in diabetic retinopathy in December 2022 and anticipate presenting interim data from this trial in 2023. We also plan to report 9- and 10-month data from the U.S. Phase 1 trial of OTX-TKI in wet AMD at the Angiogenesis meeting in February 2023. Lastly, we plan to present much anticipated data from our Phase 2 clinical trial of OTX-TIC for the treatment of glaucoma in Q4 2023. Overall, executing efficiently and working within the constraints of existing resources, we believe that the Company can pull forward our core development programs to be Phase 3-ready.”

Business Updates

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 fourth quarter of 2022 is estimated to be $13.6 million, which would represent growth of approximately 14% over the previous quarter and approximately 11% over the fourth quarter of 2021. DEXTENZA net product revenue for the year is estimated to be $50.2 million, which would represent growth of 20% over 2021.
• The Company believes DEXTENZA remains poised for continued growth in 2023 with continued drug payment in the ambulatory surgery center (ASC) setting through the non-opioid pain provision and with a focus on the growing ophthalmic surgery market, more than offsetting the loss of reimbursement in the hospital outpatient department (HOPD) setting.

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

• The Company presented positive interim 6- and 7-month data from its U.S.-based Phase 1 trial of OTX-TKI for the treatment of wet AMD at the American Academy of Ophthalmology 2022 Annual Meeting.
  • Interim data showed a single OTX-TKI implant was generally well tolerated with no drug-related ocular or systemic serious adverse events (SAEs).
  • 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.
  • 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).
• The Company intends to present 9-and 10-month interim data at the upcoming Angiogenesis, Exudation, and Degeneration 2023 Meeting at 8:10 am on Saturday, February 11th, 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 being in position to initiate a Phase 2/3 clinical trial for the treatment of wet AMD as early as Q3 2023, subject to obtaining additional funding for the trial from external sources, including potentially a strategic alliance.

OTX-TKI (axitinib intravitreal implant) for the potential treatment of Diabetic Retinopathy (DR)

• The Company believes that the interim 7-month data from the U.S.-based Phase 1 clinical trial evaluating OTX-TKI for the treatment of wet AMD, as well as the product’s mechanism of action, support proof of concept for the potential treatment of VEGF-mediated retinal vascular diseases, including diabetic retinopathy.
• DR represents a large, unmet need without an established standard-of-care treatment. Studies show treatment rates as low as 15% in patients with type 2 diabetes and DR is the leading cause of blindness in American working-age adults. Nearly 24,000 patients go blind from DR complications each year in the United States despite DR being a highly treatable disease with early diagnosis and treatment. Patients at risk for or suffering from DR may benefit from the extended durability of a treatment lasting 6 to 12 months. The Company believes that the lack of a standard of care for the treatment of DR may offer a straightforward regulatory path.
• The Company initiated a U.S.-based Phase 1 clinical trial for the treatment of DR in December 2022. This trial will include approximately 10 sites and is designed to include approximately 21 patients randomized 2:1 to either a 600 µg OTX-TKI single implant containing axitinib or sham control.
• Subject to the results of this trial, discussions with the FDA and additional financing to fund the trial, the Company believes it could be well-positioned to initiate its first Phase 3 pivotal trial for the treatment of DR as early as Q1 2024.

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

• The Company continues to 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 trial is designed to evaluate whether OTX-TIC can demonstrate a clinically meaningful decrease in intraocular pressure while preserving endothelial cell health while enabling repeat dosing.
• Due to observed elevations in intraocular pressure in the OTX-TIC 5 µg arm of the trial, the Company has decided to terminate enrollment in the 5 µg arm of the trial and continue forward with the OTX-TIC 26 µg and Durysta^® arms of the trial. The Company expects that the Phase 2 clinical trial will consist of approximately 86 patients: approximately 35 patients in the OTX-TIC 26 µg treatment arm, 35 patients in the Durysta arm and 16 patients that were previously enrolled in the OTX-TIC 5 µg treatment arm.
• The Company plans to provide top-line data from the trial in Q4 2023.

OTX-DED (dexamethasone intracanalicular insert) for the short-term treatment of the signs and symptoms of dry eye disease and OTX-CSI (cyclosporine intracanalicular insert) for the chronic treatment of dry eye disease

• The Company continues to advance both dry eye programs and plans to launch a small study in the first half of 2023 to evaluate the performance of OTX-DED versus fast-dissolving collagen plugs and no inserts at all in order to identify a proper placebo control for any future trials of these product candidates.
• The Company plans to use the results of this study to inform the next steps for both OTX-DED and OTX-CSI.

2022 Preliminary Results

• On a preliminary basis, total net product revenue for Q4 2022 and the full year 2022 are estimated to be approximately $13.6 million and approximately $50.2 million, respectively. Sequential quarterly growth from Q3 2022 to Q4 2022 is expected to be approximately 14%, signaling a return to quarterly growth from DEXTENZA, driven by sales for the treatment of post-surgical inflammation and pain. Growth in annual total net product revenue from 2021 to 2022 is estimated to be approximately 15%.
• On a preliminary basis, the Company had estimated cash and cash equivalents of $102.3 million as of December 31, 2022. Consistent with the strategy of bringing the Company’s core development programs in wet AMD, diabetic retinopathy, glaucoma and dry eye to Phase 3-ready status, the Company believes that it has sufficient cash and cash equivalents to fund planned operating expenses, debt service obligations and capital expenditure requirements through the middle of 2024.
• The Company plans to post an updated corporate presentation that can be found in the ‘Investors’ section of its corporate website on Monday, January 9, 2023.
