• 1 other identifier: QA102-CS201
• Study Type: interventional
• Target: 150
• Locations: 1 country
• Sites: 29

Brief Summary

This is a phase 2, double-masked, randomized, placebo-controlled, dose-response study. The primary objective of the study is to evaluate the efficacy of QA102 oral capsules on the development of soft drusen, visual acuity (VA), and geographic atrophy (GA) or choroidal neovascularization (CNV) or the progression of GA in subjects with intermediate to advanced dry AMD.

Conditions

Dry Age-related Macular Degeneration

Outcome Measures

• Subject must be willing and able to comply with study procedures and examinations.
• Specific to the Study Eye:
• Subject must have one of the following:
• extensive intermediate-size drusen, or at least 1 large drusen, or
• GA ((not involving the foveal center point) secondary to AMD, with very limited aggregate size of total GA(s), as defined in the protocol.
• Subject must be able to correctly identify ≥35 ETDRS letters (approximately 20/200 Snellen equivalent).
• Specific to Fellow Eye:
• \- Subject must have a diagnosis of advanced AMD (evidence of GA and/or CNV), to be confirmed by the CRC.
• Specific to Both Eyes:
• \- Subject must have visualizable retina, clear ocular media, and adequate pupillary dilation to ensure high-quality fundus imaging.

You may not qualify if:

• Subject received an active investigational drug within 6 weeks (or 5 half-lives of the active, whichever is longer) prior to screening for this QA102 study.
• Subject has ever received gene therapy (for any condition).
• Subject is unwilling to stop intake of Age-Related Eye Disease Studies (AREDS) vitamins for the duration of the study.
• Subject has a clinically significant systemic disease that might interfere with the study, in the judgment of the Investigator.
• Subject had major surgery within 30 days prior to Screening.
• Specific to Study Eye:
• Subject has large GA, subfoveal GA, or active or inactive CNV, as confirmed by the CRC.
• Subject has GA or CNV due to causes other than AMD that that developed between Visit 1 (Screening) and Visit 2 (Randomization).
• Subject has endophthalmitis.
• Subject has a hemorrhagic or serous pigment epithelial detachment (PED) within 500 µm of the foveal center point, to be confirmed by the CRC.
• Subject has had retinal procedures or surgeries, or has a retinal pathology, such as a macular hole.
• Subject has aphakia or absence of the posterior capsule.
• Subject has ever received, whether in an interventional trial or by prescription, an FDA- approved treatment for GA. Use of such treatment during the QA102 study period also is prohibited. (Study Eye Only)
• Specific to Fellow Eye:
• Subject has monocular vision impairment, defined as having no light perception in the fellow eye with adequate vision in the study eye.
