Ocular Therapeutix™ Presents Interim Topline Data from the Phase 1 Clinical Trial of OTX-TIC in Patients with Primary Open Angle Glaucoma or Ocular Hypertension at the 10th Annual Glaucoma 360 New Horizons Forum
The Phase 1, prospective, multi-center, open-label, clinical trial is intended to evaluate safety, biological activity, durability, and tolerability of OTX-TIC for the reduction of elevated intraocular pressure (IOP) in patients with primary open angle glaucoma or ocular hypertension. Interim data presented at Glaucoma 360 are from the four fully enrolled cohorts (cohort 1=5 subjects, cohort 2=4 subjects, cohort 3=5 subjects, and cohort 4=5 subjects). Formulations of cohort 3 and 4 hydrogel implant include composition for faster dissolution when compared with cohorts 1 and 2.
In this Phase 1 clinical trial, all cohorts experienced a mean reduction in IOP from baseline of 7-11 mm Hg with onset of action as early as two days after insertion. Many subjects across the four cohorts demonstrated durability of activity of 6 months or longer with a single implant. Overall, no serious ocular adverse events were noted. The hydrogel drug delivery system consistently biodegraded in 5-7 months in cohorts 1 and 2 and in 3-5 months in cohorts 3 and 4. No meaningful changes in endothelial cell counts or pachymetry were observed across the cohorts. Evaluation remains ongoing for cohort 4. As is typical for early stage clinical trials, this trial is not powered to measure efficacy endpoints with statistical significance.
“Compliance with topical drop therapy remains a clinical problem in the treatment of glaucoma and represents a large unmet medical need. OTX-TIC was developed to deliver travoprost for an extended duration of time and, if shown to be safe and effective, represents a possible solution to this problem. Continued long-term evaluation is ongoing but we are very excited by what we have seen with the early results from this trial,” commented Dr. Goldstein. “We continue to believe that OTX-TIC has the potential for a unique and differentiated drug product profile. Based on these data we continue to plan to initiate a Phase 2 clinical trial in mid-2021.”
OTX-TIC is designed to be a bioresorbable intracameral implant containing micronized travoprost that is injected into the anterior chamber of the eye and is intended for patients with glaucoma or ocular hypertension with a target duration of drug delivery of four months or longer. OTX-TIC is designed to directly address compliance issues by delivering travoprost over the course of several months with a single implant.
Glaucoma is a progressive and highly individualized disease in which elevated levels of IOP are associated with damage to the optic nerve, which results in irreversible vision loss. According to the World Health Organization, glaucoma is the second leading cause of blindness in the world. The Glaucoma Research Foundation estimates that over three million Americans have glaucoma.
To lower IOP, physicians typically initiate treatment by prescribing drugs administered as eye drops. These drugs either decrease fluid production or enhance fluid drainage. The classes of topical drugs used to treat glaucoma include prostaglandin analogs, or PGAs, beta-blockers, alpha-adrenergic agonists and carbonic anhydrase inhibitors. PGAs are the most widely prescribed class of drugs for glaucoma and are considered first-line glaucoma treatment. PGAs reduce IOP by enhancing the clearance and drainage of ocular fluid. The most frequently prescribed PGA is once-daily latanoprost, although travoprost, unoprostone and bimatoprost are also frequently used in the management of open-angle glaucoma. In cases where glaucoma is not easily managed by a drug regimen, surgical or laser treatments may be undertaken.
According to IMS Health data, approximately 35.6 million prescriptions were filled in the United States in 2019 for drugs administered by eye drops for the treatment of glaucoma, resulting in sales of approximately $3.3 billion. A typical prescription provides approximately one month of treatment. We expect prescription volume to grow, in large part as a result of the aging population. According to IMS Health, PGAs accounted for approximately half of the prescription volume in the glaucoma market in 2019.
About Ocular Therapeutix, Inc.
Ocular Therapeutix, Inc. is a biopharmaceutical company focused on the formulation, development, and commercialization of innovative therapies for diseases and conditions of the eye using its proprietary bioresorbable hydrogel-based formulation technology. Ocular Therapeutix’s first commercial drug product, DEXTENZA, is FDA-approved for the treatment of ocular inflammation and pain following ophthalmic surgery. Ocular Therapeutix has also submitted a Supplemental NDA for DEXTENZA to include the treatment of ocular itching associated with allergic conjunctivitis as an additional approved indication. Ocular Therapeutix’s earlier stage development assets currently in Phase 1 clinical trials include OTX-TIC (travoprost intracameral implant) for the reduction of intraocular pressure in patients with primary open-angle glaucoma or ocular hypertension and OTX-TKI (axitinib intravitreal implant) for the treatment of wet AMD and other retinal diseases. Ocular Therapeutix is currently evaluating OTX-CSI (cyclosporine intracanalicular insert) for the chronic treatment of dry eye disease in a Phase 2 clinical trial. Also, Ocular Therapeutix has recently filed a Phase 2-enabling investigational new drug application for OTX-DED (dexamethasone intracanalicular insert) for the short-term treatment of the signs and symptoms of dry eye disease. Also, in collaboration with Regeneron, OTX-AFS (aflibercept suprachoroidal injection) is in pre-clinical development as an extended-delivery formulation of aflibercept for the treatment of retinal diseases. Ocular Therapeutix's first product, ReSure® Sealant, is an FDA-approved device to seal corneal incisions following cataract surgery.
