Brief Summary

This study will evaluate the therapeutic effects and safety of 800 mg ALK4290 administered daily over a 6-week dosing period in subjects with refractory wet age-related macular degeneration (wAMD).

Conditions

Wet Age-related Macular Degeneration

Keywords

Refractory wAMD

Outcome Measures

Primary Outcomes (1)

• Best Corrected Visual Acuity (BCVA)

  Mean changes in BCVA as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) testing method. The ETDRS chart assesses changes in vision based on the number of letters correctly read by the subject

  Baseline to 6 weeks

Secondary Outcomes (1)

• Incidence of Treatment-emergent Adverse Events (Safety)

  Baseline to 10 weeks

Study Arms (1)

Eligibility Criteria

• Age: 50 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Persistent exudation of SRF and IRF as documented by SD-OCT and absence of improvement in visual acuity following monthly IVT anti-VEGF therapy of at least 3 months; subject must have received their last IVT anti-VEGF injection 30 to 90 days prior to the initial screening visit
• Central subfield retinal thickness ≥ 250 microns on SD-OCT (exclusive of subretinal pigment epithelial fluid, inclusive of SRF)
• Total lesion size not greater than 12 disc areas on FA
• If present, subretinal hemorrhage must comprise \< 50% of the total lesion area on FA
• No subfoveal fibrosis or atrophy on FA
• BCVA letter score, as measured by ETDRS in the study eye, between 70 and 24 letters, inclusive, at screening
• Patients 50 years of age or older at screening visit 1
• Body mass index (BMI) between18 and ≤ 40 at screening visit 1
• Female subjects must not be pregnant or breastfeeding. Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in the study, she should inform her treating physician immediately
• Signed informed consent consistent with ICH-GCP guidelines and local legislation prior to participation in the trial, which includes medication washout and restrictions

You may not qualify if:

• Treatment with IVT anti-VEGF therapy within 30 days preceding screening visit in the study eye and/or planned concomitant IVT anti-VEGF treatment in the fellow eye during the study period
• Previous participation in any studies of investigational drugs within 1 month preceding screening visit
• Any form of macular degeneration that is not age-related (e.g., Best's disease, Stargardt's disease, Sorsby's disease, etc.)
• Additional eye disease in the study eye that could compromise BCVA (i.e., uncontrolled glaucoma (intraocular pressure \> 24) with visual field loss, clinically significant diabetic maculopathy, history of ischemic optic neuropathy or retinal vascular occlusion, vitreomacular traction, monocular vision, or genetic disorders such as retinitis pigmentosa; high myopia \> 8 diopters)
• Anterior segment and vitreous abnormalities in the study eye that would preclude adequate observation with fundus photography/FA or SD-OCT
• Intraocular surgery in the study eye within 3 months prior to screening
• Aphakia or total absence of the posterior capsule (yttrium aluminum garnet (YAG) laser capsulotomy permitted, a minimum of 1 month prior to enrollment) in the study eye
