简要总结
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).
详细描述
This study is designed to investigate the potential therapeutic effects and safety of oral ALK4290 administered 800 mg daily over a 6-week dosing period as measured by Best Corrected Visual Acuity (BCVA) in subjects with refractory wAMD (i.e., following monthly intravitreal [IVT] anti-VEGF therapy for at least 3 months in the study eye).

入选标准
- •Men and women with refractory active CNV secondary to AMD, diagnosed by a retinal specialist with all the following characteristics and ophthalmic inclusion criteria applied to the study eye:
- •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
排除标准
- •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
