A Multi-Centre, Single Arm, Open-Label Extension Study to Evaluate the Long-term Safety and Efficacy of GSK4527226 (AL101) in Participants With Early Alzheimer's Disease
The study medicine GSK4527226 is being studied in participants with Alzheimer's Disease (AD) in study 219867 (the parent study, NCT06079190). This new study is an extension of that parent study called an open-label extension (OLE). An OLE is a clinical trial where all participants receive the same study medicine. Participants must already be in study 219867 to be able to take part in this study. This study will assess the long-term safety and efficacy of GSK4527226 in participants with early AD (including mild cognitive impairment \[MCI\] and mild dementia due to AD) who have completed the parent study.

• Willing and able to give informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF).
• Availability of an adult person who has frequent and sufficient contact with the participant, is able to provide accurate information regarding the participant's cognitive and functional abilities, agrees to provide information at clinic visits, and signs the study partner ICF.
