We're still translating this one. In a couple of days, you'll see what this trial actually tests — and whether it matters for APOE4 carriers like you. For now, here's the sponsor's own description:

The purpose of the study is to evaluate if there is a specific association between the presence of anti Rach antibodies in the CSF and the presence of a cogntive disorder in myasthenic patients. Moreover the investigator wants to study if there is a link between the presence of Anti RACH antibodies in myasthenia and Alzheimers's disease. For that, the investigator will recruit myasthenic patient with cognitive disorder that has undergo a diagnostic process including lombar punction for memory trouble in Nice memory center as well as Alzheimer's patient having go through the same process. The study will consist in one additionnal blood draw. Anti RACH antibodies will be analyzed in historical CSF stored in biocollection and serum collected for the study.
