Gene Therapy for APOE4 Homozygote of Alzheimer's Disease

Korábbi kezelés

• Individuals receiving systemic immunosuppressant or corticosteroid therapy other than protocol-specified, are receiving a monoclonal anti-amyloid therapy (example, Aduhelm™ (aducanumab), Leqembi™ (lecanemab-irmb) or unable to wash out from anti-coagulant medications.
• Presence of other significant medical, psychiatric, or neurological conditions may disqualify the participant from participation in this study, particularly those which would create an unacceptable risk of receiving the LX1001-01 vector, for example, malignancy, heart failure, liver or renal failure, or HIV positive.
• Prior or concurrent participation in any gene and/or cell therapy
• Individuals who cannot undergo study-related procedures without general anesthesia (other than who need general anesthesia for the gene therapy administration)
• More than 4 cerebral microhemorrhages (regardless of their anatomical location or diagnostic characterization as "possible" or "definite"), a single area of superficial siderosis, or evidence of a prior macro hemorrhage on screening MRI

Más betegség

• Individuals with a history of clinically significant hypersensitivity or contraindication as judged by the investigator, to any component of the study drug formulation or to any drugs used in this study (examples are corticosteroids and proton-pump inhibitors)

Laborértékek

• Elevated white blood cell count, temperature >38.5° C, infiltrate on chest x-ray. Note: Repeat of these examinations during the screening period is permitted to confirm eligibility
• Any condition, disorder, or abnormal laboratory test findings at screening which, in the judgment of the investigator, would interfere with the individual's ability to comply with all study requirements or would require the administration of treatment during the study that could potentially affect the interpretation of the study data, or would place the individual at unacceptable risk by his/her participation in the study
