A Study to Test How Well Different Doses of BI 771716 Are Tolerated by People With an Advanced Form of Age-related Macular Degeneration (AMD) Called Geographic Atrophy

Prior treatment

• Previously received treatment in the study eye for GA secondary to AMD within 3 months prior to screening.
• Previous trial participation receiving trial medication for GA in the study eye secondary to AMD within 6 months prior to screening. Use of any investigational drug within 90 days or 5 half-lives prior to screening, whichever is longer.
• Previously received gene therapy or cell therapy.
• Exclude prior vitrectomy surgery.

Other illness

• History of or evidence of current active exudative choroidal neovascularization (CNV) in the study eye. History of evidence of exudative CNV in the fellow eye is not exclusionary. Eyes with evidence of non-exudative CNV are not exclusionary (as identified by spectral domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA)) .
• Additional eye disease in the study eye that could compromise trial participation:
  • uncontrolled glaucoma or intraocular pressure \>24 mmHg.
  • clinically significant diabetic maculopathy.
  • history of high myopia \>8 diopters in the study eye.
  • anterior segment and vitreous abnormalities in the study eye that would preclude adequate observation with Spectral domain optical coherence tomography (SD-OCT).
  • exclude ocular conditions at discretion of the investigator that might interfere with outcome of the trial.
• Exclude study eyes that have undergone glaucoma drainage implantation or trabeculectomy. History of microinvasive glaucoma surgery may be included.
  • Further exclusion criteria apply.

Other

• Women of childbearing potential (WOCBP) cannot be included. A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy or another cause as determined by the investigator (e.g. Müllerian agenesis). Tubal ligation is NOT a method of permanent sterilization. A postmenopausal state is defined as no menses for 1 year without an alternative medical cause.

• Men and women with geographic atrophy (GA) secondary to age-related macular degeneration (AMD), with any GA lesion of minimum 1 disc diameter (minimum 2.5 mm\^2) in size, and unlimited maximum size. This may include GA lesions contiguous to or continuous with peripapillary atrophy.
• Fellow eye is not required to have GA.
• Best corrected visual acuity (BCVA) in the non-study eye must have a better BCVA compared to the study eye.
• BCVA of ≥4 and ≤70 letters in the study eye (approximate equivalent to 20/800 and 20/40 on the Snellen chart) measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol.
• Age at least 50 years.
• Men able to father a child must be ready and able to use highly effective methods of birth control per the International Council on Harmonisation of Technical Requirements for Registration of Human Use guideline M3(R2) (ICH M3(R2)) that would result in a low failure rate of less than 1% per year when used consistently and correctly.
• Signed informed consent consistent with ICH good clinical practice (GCP) guidelines and local legislation prior to participation in the trial, which includes medication washout and restrictions.
• Not under any administrative or legal supervision or under institutionalization due to regulatory or juridical order.
