MRI scan at screening showing a single area of cerebral vasogenic edema, superficial siderosis, or evidence of a previous macro-hemorrhage or showing more than 4 cerebral microhemorrhages (regardless of their anatomical location or diagnostic characterization as "possible" or "definite"). Evidence of space occupying lesions other than benign meningioma of less than 1 cm diameter, more than 2 lacunar infarcts, or 1 single infarct larger than 1 cm in diameter. Screening MRI scan showing structural evidence of alternative pathology not consistent with AD and is considered to be at the origin of subject\'s symptoms.\n12. Deviations from normal values for hematologic parameters, liver function tests, and other biochemical measures, judged to be clinically significant by the investigator.\n13. Subjects with a positive Human Immunodeficiency Virus (HIV-1 and 2) test at screening.\n14.

Subjects with positive syphilis serology consistent with active syphilis at screening.\n16. Subjects with presence of antibody titers related to immunological or autoimmune disorders at screening.\n17. MRI examination cannot be done for any reason, including but not limited to metal implants contraindicated for MRI and/or severe claustrophobia.\n18. Any contraindication for PET scan imaging.\n19. Any contraindication to lumbar puncture in subjects undergoing this procedure (note: lumbar puncture is optional in subjects with DS).\n20. Previous treatment with ACI-24 or any other active immunotherapy against AD at any time in the past unless there is firm evidence that the subject received placebo only and the placebo formulation is not expected to induce any specific immune response.\n21. Previous treatment with any investigational and/or marketed passive immunotherapy against AD within 6 months before screening or 5 half-lives, whichever is longer, unless there is firm evidence that the subject received placebo only.\n22. Ongoing treatment with any approved anti-amyloid passive immunotherapy for Alzheimer\'s disease.\n23. Use of acetylcholinesterase inhibitor or glutamatergic drugs (eg, memantine, topiramate, lamotrigine) if not on stable dose for at least 2 months before screening.\n24. Any vaccine, either live or not, including but not limited to influenza or COVID-19 vaccine, received within 4 weeks before randomization.\n25. Subjects with treated hypothyroidism not on a stable dose of replacement medication for at least 2 months before screening and having clinically significant abnormal serum T4 and/or thyroid stimulating hormone at screening.\n26. Subjects undergoing lumbar puncture and being treated with any anticoagulants or antiplatelet drugs, except aspirin at doses of 100 mg daily or lower.\n27. Use of antidepressants (other than selective serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors at stable dose); typical antipsychotics; γ-aminobutyric acid agonists (eg, gabapentin); or stimulants (eg, methylphenidate, modafinil). Stable doses of atypical antipsychotics or benzodiazepines are only allowed if this is not considered to influence the safety and the efficacy of the study treatment according to the site investigator and the sponsor medical monitor.\n28. Chronic use of opioid analgesics. A limited treatment duration for acute conditions until 24 hours before cognitive assessment is allowed.\n29. Current use of immunosuppressant or immunomodulating drugs or their use within the 6 months before study screening. Current use of oral steroids or their use within the 3 months before study screening.\n\n Additional Exclusion Criteria in Study Part 2\n\n The following are exclusion criteria at the time of randomization but will not be considered as exclusionary after treatment assignment:\n30. Clinical diagnosis of AD dementia in DS as per International Classification of Diseases 10 (ICD-10).\n31. DSQIID \\>20.\n32. Intelligence quotient score \\<40 (KBIT-2).'}, 'identificationModule': {'nctId': 'NCT05462106', 'briefTitle': "A Study to Assess the Effects of ACI-24.060 in Alzheimer's Disease and in Down Syndrome (ABATE Study)", 'organization': {'class': 'INDUSTRY', 'fullName': 'AC Immune SA'}, 'officialTitle': "A Phase 1b/2, Multicenter, Adaptive, Double-blind, Randomized, Placebo-controlled Study to Assess the Safety, Tolerability, Immunogenicity, and Pharmacodynamic Effects of ACI-24.060 in Subjects With Prodromal Alzheimer's Disease and in Adults With Down Syndrome (ABATE)", 'orgStudyIdInfo': {'id': 'ACI-24-AD-DS-2102'}, 'secondaryIdInfos': [{'id': '2021-006195-17', 'type': 'EUDRACT_NUMBER'}, {'id': '2022-500069-29-00', 'type': 'OTHER', 'domain': 'European Union Drug Regulatory Authorities Clinical Trial System'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo for Study Part 1 (Prodromal AD)', 'description': 'Prodromal AD participants receive placebo at predefined time points over 48 weeks', 'interventionNames': ['Biological: Placebo']}, {'type': 'EXPERIMENTAL', 'label': 'ACI-24.060 at Dose A in Prodromal AD', 'description': 'Prodromal AD participants receive dose A of ACI-24.060 at predefined time points over 48 weeks', 'interventionNames': ['Biological: ACI-24.060 at Dose A']}, {'type': 'EXPERIMENTAL', 'label': 'ACI-24.060 at Dose B in Prodromal AD', 'description': 'Prodromal AD participants receive dose B of ACI-24.060 at predefined time points over 48 weeks.', 'interventionNames': ['Biological: ACI-24.060 at Dose B']}, {'type': 'EXPERIMENTAL', 'label': 'ACI-24.060 at Dose C in Prodromal AD', 'description': 'Prodromal AD participants receive dose C of ACI-24.060 at predefined time points over 48 weeks.', 'interventionNames': ['Biological: ACI-24.060 at Dose C']}, {'type': 'EXPERIMENTAL', 'label': 'ACI-24.060 at Dose D in Prodromal AD (Optional)', 'description': 'Prodromal AD participants receive dose D of ACI-24.060 at predefined time points over 48 weeks.
