A Study to Test Different Doses of BI 1584862 in People With a Distinct Form of Age-related Macular Degeneration (AMD) Called Geographic Atrophy

Inclusion criteria: * Men and women with at least 1 eye with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) determined by fundus autofluorescence (FAF). The total size of all GA lesions in the study eye (as determined by the independent central reading center (CRC)) must be ≥1.25 mm\^2 and ≤12.0 mm\^2: * If multiple lesions are present in the study eye, at least 1 lesion must have an area of ≥0.5 mm\^2 * At least 1 GA lesion must be at least in part within a 1500 μm radius ring centered on the fovea * The foveal center point must not be involved in any atrophic lesion * Lesion(s) must reside completely within the FAF image * Best corrected visual acuity (BCVA) score of ≥50 letters in the study eye using the early treatment diabetic retinopathy study (ETDRS) chart (approximately equivalent to ≥20/100 on the Snellen chart). * Hyperautofluorescence of any pattern, as assessed by the CRC, must be present in the junctional zone of GA in the study eye. * Age ≥50 years. * Men must be willing and able to use contraception (condom, abstinence) to prevent pregnancy and/or exposure of an existing embryo or fetus to the investigational product. A female participant is eligible if she is not a woman of childbearing potential. * Signed informed consent consistent with International Conference of Harmonization-Good Clinical Practice (ICH GCP) guidelines and local legislation Exclusion criteria: * Any history of, or evidence of, exudative age-related macular degeneration (eAMD) in the study eye. * Previously received treatment for GA in the study eye within 4 months or 5 half-lives, prior to baseline, whichever is longer. * Previously received an investigational medication (oral or intravitreal) for GA within 4 months or 5 half-lives prior to baseline, whichever is longer. * Additional eye disease in the study eye that could compromise BCVA or significantly impact retinal morphology: * uncontrolled glaucoma, defined as a disk-to-cup ratio \>0.8 or ocular hypertension with intra ocular pressure (IOP) \>24 mmHg at screening visit, or use of \>2 active IOP-lowering agents in the study eye * clinically significant diabetic retinopathy or maculopathy in the opinion of the investigator * history of high myopia, i.e. spherical equivalent of ≥8 diopters or axial length ≥27.2 mm. Note: if subject had prior cataract or refractive surgery, spherical equivalent should be evaluated with pre-operative refraction. If axial length measurement is not available in medical records and cannot be obtained at screening visit, assessment of high myopia can be made by investigator on clinical examination. * anterior segment and vitreous abnormalities that would preclude adequate observation with SD-OCT in the opinion of the investigator * other ocular conditions at the discretion of the investigator that might interfere with the outcome of the trial * Significant disease or other medical conditions (as determined by medical history, examination, and clinical investigations at screening) that may, in the opinion of the investigator result in any of the following: * put the participant at risk because of participation in the study * influence the results of the study * cause concern regarding the participant's ability to comply with the protocol requirements or complete the trial as scheduled (e.g. chronic alcohol or drug abuse or any other condition that, in the investigator's opinion, makes the participant an unreliable trial participant) * Known hypersensitivity to any of the ingredients used in the investigational medicinal product (IMP) formulation, or any of the medications used. * Active intraocular inflammation in the study eye. * Active infectious conjunctivitis in either eye. Further exclusion criteria apply.
