Study to Evaluate Safety and Efficacy of EG-301 in Patients With Nonfocal Geographic Atrophy Secondary to Dry-AMD

Korábbi kezelés

• Females who are pregnant, nursing, planning a pregnancy during the study or who are of childbearing potential not using a reliable method of contraception and/or not willing to maintain a reliable method of contraception during their participation in the study. Women of childbearing potential with a positive urine pregnancy test administered at baseline are not eligible to receive study drug
• Prior cataract surgery is allowed up to 90 days before the baseline visit, but refractive surgery in either eye may not be conducted during the study.
• Subjects who have received any drug or herbal medicine known to inhibit CYP2D6 enzyme activity prior to the first dose of the investigational drug (the patient can be enrolled if the washout period is ≥5 half-lives of the CYP2D6 inhibitor), or subjects who need to continue receiving these medications during the study period. (Refer to Appendix 1 for a list of CYP2D6 inhibitors)

Laborértékek

• Subjects with moderate or severe renal impairment as indicated by an estimated glomerular filtration rate (eGFR) <60 mL/min, calculated by using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)

Egyéb

• Subject with exudative AMD or choroidal neovascularization (CNV), including any evidence of retinal pigment epithelium rips, detachments or evidence of neovascularization anywhere in either eye based on SD-OCT imaging and/or fluorescein angiography as assessed by the Reading Center
• Subjects who had anti-VEGF IVT in either eye in the past 90 days

• Male or female patients, 50 to 75 years of age at screening visit
• Subject has signed the Informed Consent form
• Subjects with intermediate nonfocal geographic atrophy secondary to Non-Exudative (dry) AMD having ETDRS BCVA between 35 and 80 letters read (equivalent to 20/25 - 20/200 on Snellen Chart) with the level of vision caused by the non-exudative AMD and no other factor/s
• Subjects with symptomatic decrease in visual acuity in the last 12 months
• Subjects with confirmed diagnosis of geographic atrophy (GA) secondary to dAMD in the study eye* as evidenced by the following characteristics:
  • Non-center involving GA lesions that reside completely within the FAF imaging field (field 2, 30 degree image centered on the fovea)
  • Total GA area is ≥2.5 and ≤ 17.5 mm2 (1 and 7 disk areas [DA])
  • If GA is multifocal, at least one focal lesion must be >1.25 mm2 (0.5 DA)
  • Combination of areas of RPE disturbances described as a pattern of hyper or hypo-pigmentation in the junctional zone of GA. Absence of hyper-autofluorescence is exclusionary
• Subjects with evidence of reasonably well-preserved areas of RPE by clinical examination and well-defined RPE and outer segment ellipsoid line by OCT examination in the central 1 mm of the macula as confirmed by the central reading center. More specifically, reasonably well- preserved central 1 mm of the macula means:
  • The RPE and outer retinal layers throughout the central 1 mm are intact
  • No signs of NVAMD such as intraretinal or sub retinal fluid, or sub retinal hyper-reflective material
  • No serous pigment epithelium detachments >100 microns in height
  • Sufficiently clear ocular media, adequate pupillary dilation, fixation to permit quality fundus imaging, and able to cooperate sufficiently for adequate ophthalmic visual function testing and anatomic assessment
