Clinical trials

Age-related macular degeneration (AMD) affects millions of elderly patients. When advanced, there is Geographic Atrophy (GA) in the retina. This means that there is an area with a loss of light-sensitive cells, called photoreceptors. That part of the retina can no longer see. Atrophy begins as a small spot in the retina distant from the fovea which is the part of the retina responsible for sharp central vision. The GA grows, and when it reaches the fovea, vision is severely diminished, and details cannot be seen anymore. The purpose of the eDREAM study is to understand if GAL-101 can slow the growth of GA and prevent it from reaching the fovea. GAL-101 is given as eyedrops. eDREAM patients will administer study eyedrops every day. Patients will be assigned by chance (randomly) to receive either eye-drops that contain the new medication, GAL-101, or eyedrops without the active drug (Placebo). Neither patients nor doctors will know which treatment was assigned to each patient until the end of the study.

This Phase 2a study will evaluate the safety and tolerability of GAL-101 in approximately 100 participants with mild to moderate Alzheimer's disease associated with amyloid-beta pathology. Participants will be randomly assigned to receive either 1200 mg of GAL-101 salt or matching placebo tablets by mouth once daily for 28 days. Neither the participants nor the study team will know which treatment each participant receives during the study. The study will also explore whether GAL-101 affects brain-wave activity measured using quantitative electroencephalography, Alzheimer's disease-related biomarkers in cerebrospinal fluid, and performance on cognitive tests. Blood and cerebrospinal fluid samples will be collected to evaluate how GAL-101 is absorbed and distributed in the body.
