Ocular Therapeutix™ Announces Positive Topline Phase 1 Data for AXPAXLI™ in Diabetic Retinopathy

46.2% of patients demonstrated a 1- or 2-step improvement in the Diabetic Retinopathy Severity Scale (DRSS) at 40 weeks in the AXPAXLI arm, compared to 0% in the control arm

No patients in the AXPAXLI group experienced worsening in DRSS compared to 12.5% in the control arm at 40 weeks

AXPAXLI was generally well tolerated with no inflammation observed

Ocular intends to present the Phase 1 HELIOS study at an upcoming meeting

BEDFORD, Mass., April 18, 2024 (GLOBE NEWSWIRE) -- Ocular Therapeutix, Inc. (NASDAQ:OCUL) (“Ocular”), a biopharmaceutical company committed to enhancing people’s vision and quality of life through the development and commercialization of innovative therapies for wet age-related macular degeneration (wet AMD), diabetic retinopathy (DR), and other diseases and conditions of the eye, today announced positive topline results from the Phase 1 HELIOS study evaluating AXPAXLI versus a sham control in patients with moderately severe to severe non-proliferative diabetic retinopathy (‘NPDR’, NCT05695417) without diabetic macular edema (DME). Ocular plans to present the study results at an upcoming meeting.

Summary of Topline Phase 1 HELIOS Results:

• Safety: AXPAXLI was generally well tolerated with no inflammation observed including no incidence of iritis, vitritis or vasculitis
• Efficacy Results: 6 of 13 (46.2%) patients in the AXPAXLI group experienced a 1 or 2-step improvement in the Diabetic Retinopathy Severity Scale (DRSS) at 40 weeks, with 2 of the 6 having a 2-step improvement. No patients in the control group showed 1- or 2-step improvement at the same time point. No patients in the AXPAXLI group experienced any worsening in DRSS. 1 of 8 (12.5%) in the control group experienced worsening in the DRSS at 40 weeks.
• Durability of Effect: A single injection of AXPAXLI provided durable DRSS improvement up to 40 weeks
• Rescue medication: No patients in either arm received rescue medication
• Next Steps: Positive HELIOS results support decision to move directly to a Phase 3 study with AXPAXLI in patients with NPDR, pending discussions with the FDA
• Data Release: Ocular plans to present topline results from the HELIOS study at a future meeting

“We are pleased to announce positive topline data for AXPAXLI in patients with diabetic retinopathy. In an effort to get AXPAXLI to patients as quickly as possible, we unmasked this study, and based on the observed safety, efficacy results and durable treatment effect, we have decided to accelerate the DR program to Phase 3. We look forward to providing additional information on our timeline for next steps, including our plans to present these results at an upcoming meeting in the coming months,” said Jeffrey S. Heier, Chief Scientific Officer (CSO) of Ocular Therapeutix.

“It is promising that the efficacy signals seen to date in this Phase 1 study consistently favor AXPAXLI. These data demonstrated DRSS improvements and durability for up to 40 weeks,” said Dilsher Dhoot, MD. “In addition, these results, combined with the results in the AMD studies of AXPAXLI, make me even more enthusiastic to be a principal investigator in the SOL-1 study.” Dr. Dhoot, of California Retina Consultants, is an internationally recognized key opinion leader in retinal diseases.

About the HELIOS study
The Phase 1 HELIOS study is a multi-center, double-masked, randomized 2:1, parallel group clinical trial conducted at 10 centers in the U.S. The data set reported here is based on 21 evaluable subjects (one patient of the 22 enrolled subjects died from an unrelated event). The study was designed to evaluate the safety, tolerability and efficacy of AXPAXLI compared to a sham control in subjects with moderately severe to severe NPDR without Diabetic Macular Edema (DME). The primary endpoint of the study is frequency of treatment emergent adverse events (TEAEs). Secondary study endpoints include changes in the DRSS, changes in best corrected visual acuity (BCVA), changes in central subfield thickness compared to baseline, and the portion of subjects receiving rescue therapy.

About AXPAXLI™
AXPAXLI is an investigational bioresorbable, hydrogel implant incorporating axitinib, a small molecule, multi-target, tyrosine kinase inhibitor with anti-angiogenic properties, being evaluated for the treatment of wet AMD, DR and other retinal diseases.
