REDEFINING DEVELOPMENT
Our complementary wet age-related macular degeneration (AMD) and diabetic retinopathy (DR) registrational trials

AXPAXLI’s potential in wet AMD:The SOL registrational trials are designed to showcase durability, repeatability, and flexibility
The SOL-X open-label extension trial evaluates long-term safety and potential disease-modifying impact

Superiority study comparing a single AXPAXLI™ (also known as OTX-TKI), an investigational axitinib hydrogel administered by intravitreal injection, dose to a single aflibercept (2mg) dose at Week 36
Design:
Two-arm trial with ~300 total subjects randomized 1:1
Primary Endpoint (Week 36):
Demonstrate that a single AXPAXLI dose is superior to a single aflibercept 2mg dose based on proportion of subjects who maintained visual acuity, defined as <15 ETDRS (Early Treatment Diabetic Retinopathy Study) letters of BCVA (best-corrected visual acuity) loss from baseline
Non-inferiority study comparing AXPAXLI Q24W to aflibercept (2mg) Q8W at Week 56
Design:
Three-arm trial with 555 total subjects randomized 2:2:1
Primary Endpoint (Week 56):
Demonstrate that a single AXPAXLI dose is non-inferior to fixed-dose aflibercept 2mg Q8W with respect to mean change from baseline in BCVA (Best-Corrected Visual Acuity) Week 56
Non-inferiority margin for the lower bound is -4.5 letters in BCVA at Week 56
Design:
Three-year follow-up with AXPAXLI Q24W to assess long-term outcomes
Key Objectives:
Demonstrate reduction in fibrosis associated with chronic exudation
Explore long-term maintenance of visual acuity
Investigate effects of delaying AXPAXLI treatment

AXPAXLI’s potential in DR:The complementary HELIOS registrational trials leverage a novel ordinal endpoint and are designed to unlock the diabetic market and support a broad DR label

Superiority study comparing a single AXPAXLI, an investigational axitinib hydrogel administered by intravitreal injection, compared to a single ranibizumab (0.3 mg) injection at Week 52
Design:
Study of AXPAXLI in ~432 subjects with moderate to severe non-proliferative diabetic retinopathy (NPDR) without center-involved (CI) diabetic macular edema (DME) randomized 1:1
Primary Endpoint (Week 52):
Ordinal DRSS 2-step change status at Week 52 from baseline (≥ 2 step improvement, ≥ 2-step worsening, less than 2-step change in either direction)
Design:
Study of AXPAXLI in ~930 subjects with moderate to severe NPDR without CI-DME randomized 1:1:1
Primary Endpoint (Week 56):
Ordinal DRSS 2-step change status at Week 52 from baseline (≥ 2 step improvement, ≥ 2-step worsening, less than 2-step change in either direction)
