Ocular Therapeutix™ Shares SOL-R Enrollment Progress and Next Steps for AXPAXLI™ in NPDR

311 subjects enrolled across various stages of loading and randomization in SOL-R, Ocular’s second registrational trial of AXPAXLI™ in wet AMD, as of January 10, 2024 First wet AMD registrational trial, SOL-1, completed randomization in December 2024 with topline data anticipated in Q4 2025 Company plans to seek FDA feedback in H1 2025 on clinical trial design for AXPAXLI in NPDR BEDFORD, Mass., Jan. 14, 2025 (GLOBE NEWSWIRE) -- Ocular Therapeutix, Inc. (NASDAQ: OCUL, “Ocular”, the “Company”), a biopharmaceutical company committed to redefining the retina experience, outlined exceptional clinical progress across its registrational program for AXPAXLI™ in wet age-related macular degeneration (wet AMD), plans to advance AXPAXLI in non-proliferative diabetic retinopathy (NPDR), and the Company’s strategic outlook for 2025 in its presentation at the 43rd Annual J.P. Morgan Healthcare Conference (JPM 2025). “Wet AMD is the leading cause of blindness in the U.S., but it does not need to be. Diabetic retinopathy is the leading cause of blindness in the working population in the U.S., but it does not need to be. We have a proven target, VEGF, and proven treatments for decades, the anti-VEGFs. Unfortunately, we also have a treatment regimen that is simply not sustainable for many patients. Our mission at Ocular is to correct this,” said Pravin U. Dugel, MD, Executive Chairman, President and Chief Executive Officer of Ocular Therapeutix. “Last year, we started with wet AMD. We recruited SOL-1 well ahead of schedule and, yesterday at JPM 2025, I announced that we have already enrolled 311 patients in various stages of loading and randomization in SOL-R, our second registrational study in wet AMD. The historic pace of recruitment in both studies underscores the enthusiasm in the retina community for AXPAXLI. In 2025, we will also target diabetic retinopathy. Our HELIOS study has demonstrated that a single injection of AXPAXLI has the potential to reduce the risk of vision loss in NPDR to literally zero at 48 weeks. In HELIOS, every single patient with non-center involved DME treated with a single injection of AXPAXLI, improved at week 48. Therefore, AXPAXLI has the potential to not only prevent vision loss, but also to treat existing vision threatening complications, such as DME.” Dr. Dugel concluded, “In 2025, Ocular will target the two most impactful global diseases in retina, wet AMD and diabetic retinopathy. We believe we have the infrastructure, finances and expertise to succeed and redefine the global retina experience.” J.P. Morgan Presentation Highlights Complementary wet AMD registrational program. Ocular’s wet AMD registrational program for AXPAXLI is comprised of two complementary studies, SOL-1 and SOL-R, strategically designed with the intent of de-risking patient populations, aligning with regulatory standards, enhancing each other’s enrollment, and providing a broad evaluation of AXPAXLI’s durability, repeatability, and flexibility. SOL-1 is being conducted under a Special Protocol Agreement (SPA) with the U.S. Food and Drug Administration (FDA), while SOL-R received alignment with the FDA through a written Type C response. The FDA previously agreed that together, these studies could constitute two adequate and well-controlled trials to support a potential New Drug Application (NDA) and label for AXPAXLI in wet AMD.SOL-1 (Phase 3, wet AMD) randomization complete in December 2024. In total, more than 300 subjects were randomized across greater than 100 clinical trial sites located in the U.S. and Argentina. SOL-1 is a superiority trial comparing a single AXPAXLI injection to a single aflibercept (2 mg) injection in treatment naïve wet AMD subjects with a nine-month primary endpoint and up to two-year follow-up. SOL-1 is the first registrational trial for AXPAXLI in wet AMD and was designed to establish AXPAXLI’s durability, and potentially enable a superiority claim on a potential future label. The Company expects topline results for SOL-1 to be available in the fourth quarter of 2025.SOL-R (Phase 3, wet AMD) outstanding enrollment progress to date. 311 subjects enrolled across various stages of loading and randomization in the U.S. and South America as of January 10, 2024. SOL-R is a non-inferiority trial comparing repeat AXPAXLI injections every six months to repeat aflibercept (2 mg) injections every eight weeks, with a 56-week primary endpoint. SOL-R is the second registrational trial for AXPAXLI in wet AMD and was designed to inform real world treatment decisions, establish AXPAXLI’s safety and efficacy with repeat dosing, and provide commercially relevant data.Ocular plans to seek FDA feedback in H1 2025 on the clinical trial design for AXPAXLI in NPDR. Following positive results from the Phase 1 HELIOS trial of AXPAXLI shared in 2024, Ocular plans to continue clinical development in NPDR. In the HELIOS trial, after a single AXPAXLI injection, no patients receiving AXPAXLI (N=13) developed a vision threatening complication (VTC) at 48 weeks compared to nearly 40% in the sham-treated patients (N= 8). Further, all patients in the AXPAXLI arm who presented with non-center-involved diabetic macular edema (non-CI-DME) at baseline (N=8) had improvement in their DME based on Optical Coherence Tomography (OCT) image analysis at week 48 compared to none of the sham-treated subjects (N=3). All subjects who received AXPAXLI showed diabetic retinopathy severity scale (DRSS) improvement or stability, while any worsening of DRSS occurred only in sham-treated subjects. Arshad M. Khanani, MD, MA, FASRS, Director of Clinic Research at Sierra Eye Associates, Reno, Nevada noted, “Real-world evidence shows that 40 to 50% of patients with wet AMD discontinue their injections due to the high treatment burden, putting them at increased risk of blindness. This issue is even more pronounced in patients with diabetic retinopathy. My team, our patients, and I are excited to support the SOL studies, and delighted that Ocular will soon target diabetic retinopathy, a huge unmet need in our space. If approved, I believe AXPAXLI will be rapidly adopted, as it has the potential to significantly reduce treatment burden with a durability of 6-12 months." Patricio G. Schlottmann, MD, Director of the Research Department at the Charles Ophthalmic Center and Ophthalmology Department Director at Organización Médica de Investigación in Buenos Aires, Argentina, commented, “Wet AMD and diabetic retinopathy are global diseases in which millions of patients around the world lose vision because we have an unsustainable treatment regimen. I continue to enthusiastically support the SOL programs in wet AMD and am particularly happy that Ocular will also target diabetic retinopathy. If approved, I believe Axpaxli will be enthusiastically adopted and has the potential to positively impact millions of patients around the world.” About AXPAXLIAXPAXLI™ (axitinib intravitreal injection, also known as OTX-TKI) is an investigational, bioresorbable, hydrogel incorporating axitinib, a small molecule, multi-target, tyrosine kinase inhibitor with anti-angiogenic properties, being evaluated for the treatment of wet AMD, diabetic retinopathy, and other retinal diseases. About the SOL-1 StudyThe registrational Phase 3 SOL-1 trial (NCT06223958) is designed to evaluate the safety and efficacy of AXPAXLI in a multi-center, double-masked, randomized (1:1), parallel group study that involves more than 100 clinical trial sites located in the U.S. and Argentina. In December 2024, the trial completed randomization of more than 300 evaluable treatment-naïve subjects with a diagnosis of wet AMD in the study eye. The superiority study has an eight-week loading segment prior to randomization, a 9-month treatment segment, and a safety follow-up. During the loading segment, subjects who have 20/80 vision or better and who satisfy other enrollment criteria receive two doses of aflibercept (2 mg) at Week -8 and Week -4. Eligible subjects who achieve best corrected visual acuity (BCVA) of 20/20 at Day 1 or gain at least 10 early treatment diabetic retinopathy (ETDRS) letters at Day 1 are then randomized to receive a single dose of AXPAXLI or a single dose of aflibercept (2 mg) and assessed monthly for the duration of the study. The clinical trial protocol requires that, during the study, subjects in any arm meeting pre-specified rescue criteria will receive a supplemental dose of aflibercept (2 mg). The primary endpoint of SOL-1 is the proportion of subjects who maintain visual acuity, defined as a loss of <15 ETDRS letters of BCVA, at Week 36. The study is being conducted under a Special Protocol Agreement (SPA) with the FDA. About the SOL-R StudyThe registrational Phase 3 SOL-R trial (NCT06495918) is designed to evaluate the safety and efficacy of AXPAXLI in a multi-center, double-masked, randomized (2:2:1), three-arm study that will involve sites located in the U.S. and the rest of the world. The trial is intended to randomize approximately 825 subjects who are treatment-naïve or were diagnosed with wet AMD in the study eye within three months prior to enrollment. The non-inferiority study reflects a patient enrichment strategy that includes multiple loading doses of aflibercept (2 mg) and monitoring to exclude subjects with significant retinal fluid fluctuations. Subjects in the first arm receive a single dose of AXPAXLI at Day 1 and are re-dosed at Week 24. Subjects in the second arm receive aflibercept (2 mg) on-label every 8 weeks. Subjects in the third arm receive a single dose of aflibercept (8 mg) at Day 1 and are re-dosed at Week 24, aligned with the AXPAXLI treatment arm for adequate masking. Subjects in any arm that meet pre-specified rescue criteria will receive a supplemental dose of aflibercept (2 mg). The primary endpoint of SOL-R is non-inferiority in mean BCVA change from baseline between the AXPAXLI and on-label aflibercept (2 mg) arms at one year. In a written Type C response received in August 2024, the FDA agreed that the SOL-R repeat dosing wet AMD study should be appropriate as an adequate and well-controlled study in support of a potential New Drug Application and product label. About Wet AMDWet age-related macular degeneration (wet AMD) is a leading cause of severe, irreversible vision loss affecting approximately 14 million individuals globally and 1.65 million in the United States alone (2023 Market Scope® Retinal Pharmaceuticals Market Report). Wet AMD causes vision loss due to abnormal new blood vessel growth and hyperpermeability and associated retinal vascularity in the macula, which is primarily stimulated by local upregulation of vascular endothelial growth factor (VEGF). Without prompt and continuous treatment to control this exudative activity, patients develop irreversible vision loss. With proper treatment, patients may maintain visual function for a period of time and may temporarily regain lost vision. Challenges with current therapies include pulsatile, repeated intraocular injections, treatment-related adverse events and up to 40% patient discontinuation within one year of initiating treatment with continued disease progression. Taken together, these factors lead to undertreatment and a lack of long-term vision improvement for patients.
