(Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods], declaration of abstinence for the duration of exposure to IMP, and withdrawal are not acceptable methods of contraception)
- Mutation Status:
- Participant is a carrier of a mutation in an APP, PSEN1, or PSEN2 gene that is associated with DIAD or does not know their mutation status and there is a mutation in their family pedigree that puts them at a direct risk of inheriting the known mutation;
- Participant is -25 to -11 years from predicted age of cognitive symptom onset based on their mutation type or family pedigree Note: If the at-risk parent is deemed a non-carrier through confirmed genetic testing at any time during the study, the participant will be withdrawn.
- Cognitive status of participant is normal (CDR-SB 0).
- Fluency in DIAN-TU trial approved language and evidence of adequate premorbid intellectual functioning. Participants must be fluent in languages for which cognitive and clinical measures have been translated and validated for use in the DIAN-TU. Fluency is generally defined as daily or frequent functional use of a language generally from birth or a young age. In cultures where multiple languages are spoken or for participants who are multilingual, determination as to whether a participant's level of fluency in languages for which clinical and cognitive measures are available meets qualification for the study should be made by the site PI.

About this study
Official title: A Phase II/III Multicenter Randomized, Double-Blind, Placebo-Controlled, Two-Stage Adaptive Design, Platform Trial of Investigational Treatments for Primary Prevention of Disease Progression in Dominantly Inherited Alzheimer's Disease
The purpose of this research study is to test the study drug, referred to as remternetug, to determine its effectiveness for the study treatment of asymptomatic (at risk) Alzheimer disease in individuals with AD-causing mutations. This study will also investigate the effects of remternetug on biomarkers (measures of the disease including brain scans, blood and spinal fluid tests), examine safety data to identify any potential benefits or risks, and examine how well participants can tolerate remternetug.
Stage 1 will determine if treatment with the study drug prevents or reverses amyloid beta (Aβ) accumulation compared with placebo in participants with dominantly inherited Alzheimer's disease (DIAD).
Stage 2 will evaluate the effect of early anti-amyloid treatment on downstream biomarkers of AD in treated participants compared to external control groups.
Read the detailed description
Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by progressive decline in cognitive function and the ability to perform activities of daily living. The amyloid hypothesis of AD postulates that the accumulation of amyloid beta (Aβ) is an early and necessary event in the pathogenesis of AD. This hypothesis suggests that interventions that slow the accumulation of Aβ plaque in the brain or increase clearance of Aβ may be able to slow the progression of the AD clinical syndrome. AD occurs on a continuum from asymptomatic (preclinical) to mild cognitive impairment (MCI), and then to dementia in mild, moderate, and severe stages. Evidence from both genetic at-risk and age at-risk cohorts, such as in dominantly inherited AD (DIAD) suggests that the pathophysiological process of AD begins well more than a decade before the clinical stage now recognized as AD dementia, and that neurodegeneration is already apparent on MRI by the stage of mild cognitive impairment. Recent clinical trial data suggest that treating AD during the earlier stages could have the greatest potential benefit on the disease by slowing progression
The ability to identify individuals destined to develop Alzheimer's disease (AD) with a high degree of confidence provides a unique opportunity to assess the efficacy of therapies at asymptomatic and very early stages of dementia. Families with known disease-causing mutations are extremely rare and are geographically dispersed throughout the world.
Participants in this study will not yet have developed any clinical symptoms of AD; they will be "asymptomatic" carriers of mutations that cause DIAD and would be expected to perform normally on standard cognitive and functional testing. Further, most mutation carriers will have levels of AD-associated amyloid beta (Aβ) and non-Aβ biomarkers that are the same as non-carriers.
Amyloid beta is a protein that accumulates in the brain of people with AD. Although we do not understand exactly what causes AD, the abnormal accumulation of amyloid beta protein in the brain is thought to play an important role in the symptoms of AD. Recent research studies indicate that amyloid beta may start building up in the brain 15 years or more before the onset of memory loss.
Imaging and fluid biomarkers will be used to demonstrate that the treatment compounds have engaged their therapeutic targets. A set of cognitive measures designed to assess the very earliest and most subtle cognitive changes will be collected. The overall objectives of this study are to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an AD-causing mutation.
The primary objective of Stage 1 is to determine if treatment with the study drug prevents or slows the rate of Aβ pathological disease accumulation demonstrated by Aβ PiB positron emission tomography (PET) imaging.
The primary objective of Stage 2 is to evaluate the effect of early anti-amyloid treatment on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, NfL, MRI volume) compared to a control group from the DIAN Obs natural history study and the DIAN-TU-001 placebo-treated participants.
Remternetug is a monoclonal antibody. The mechanism of action of remternetug is to target and remove aggregated amyloid plaque, a key pathological hallmark of AD, via microglial-mediated clearance. Remternetug has demonstrated the ability to reduce brain amyloid plaque.
The remternetug arm is part of Master Protocol DIAN-TU-002 (NCT05552157)

What is being measured
The primary outcome is the main question the study is designed to answer.
Stage 1: Change in amyloid load as measured by centiloid (CL) [11C]PiB-PET as biomarker endpoint for DIAN-TU-002 remternetug arm
CL calculated using [11C] PiB PET non-partial volume corrected (regional spread function) standardized uptake value ratio cortical composite (PiB PET SUVR) is the primary outcome and change from baseline at 2 years is the primary endpoint.
Measured: Baseline and Week 192
Secondary outcomes (7)
Stage 2: Odds ratio between the drug-treated and control groups of being in the lower biomarker disease progression stage based on two-stage modeling of 6 biomarkers.
The key secondary efficacy endpoint for Stage 2 is the odds ratio between the treated group and the external control group (DIAN Obs and DIAN-TU-001 placebo) of being in the lower biomarker disease progression stage based on two-stage modeling of 6 biomarkers (CSF tau phosphorylated tau at residue 153 (pTau153)/Tau153 ratio, CSF pTau205/Tau205 ratio, CSF microtubule binding region of tau 243 amino acids long (MTBR-tau243), MRI hippocampal volume, CSF neurofilament light chain (NfL), and MRI precuneus thickness).
Measured: Weeks 0, 48, 96, 144, and 192
Stage 1: The proportion of participants who are amyloid positive (CL level ≥ 16.3) at the end of Stage 1
For participants in the active treatment group, the amyloid positivity status is defined using the last available PiB-PET CL value during Stage 1: amyloid positive if CL>=16.3 and amyloid negative if CL<16.3. For participants in the placebo group, the amyloid positivity status: (i) is either defined using the last available PiB-PET CL value during Stage 1 (amyloid positive if CL>=16.3 and amyloid negative if CL<16.3)
Measured: Baseline and Week 104
Stage 1: Change in CSF pTau217/Tau217 ratio
Measured: Baseline and Week 104
Stage 1: Change in CSF pTau231/Tau231 ratio
Measured: Baseline and week 104
Stage 1: Change in CSF 3-repeat isoform of MTBR (MTBR-3R)
Measured: Baseline and week 104
Stage 2: Change in CSF pTau217/Tau217 ratio CSF pTau231/Tau231 ratio, and CSF MTBR-3R
Measured: Weeks 0, 48, 96, 144, and 192
Stage 2: Change in Cognitive Composite Score
A cognitive composite derived as an average of these four tests: Memory Complaint Questionnaire (MAC-Q), Category Fluency (Animals), Buschke and Grober Free and Cued Selective Reminding Test - Immediate Recall (FCSRT-IR), Wechsler Adult Intelligence Scale - Revised (WAIS-R) Digit Symbol Substitution Test, and Mini-Mental State Examination (MMSE). Each of the four tests will be converted to a z-score using the mean (SD) of the baseline score in Stage 1 of both the treatment arm and the placebo arm, and then equally weighted to obtain the composite.
Measured: Weeks 0, 48, 96, 144, and 192

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this research study is to test the study drug, referred to as remternetug, to determine its effectiveness for the study treatment of asymptomatic (at risk) Alzheimer disease in individuals with AD-causing mutations. This study will also investigate the effects of remternetug on biomarkers (measures of the disease including brain scans, blood and spinal fluid tests), examine safety data to identify any potential benefits or risks, and examine how well participants can tolerate remternetug.
Stage 1 will determine if treatment with the study drug prevents or reverses amyloid beta (Aβ) accumulation compared with placebo in participants with dominantly inherited Alzheimer's disease (DIAD).
Stage 2 will evaluate the effect of early anti-amyloid treatment on downstream biomarkers of AD in treated participants compared to external control groups.
Detailed description
Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by progressive decline in cognitive function and the ability to perform activities of daily living. The amyloid hypothesis of AD postulates that the accumulation of amyloid beta (Aβ) is an early and necessary event in the pathogenesis of AD. This hypothesis suggests that interventions that slow the accumulation of Aβ plaque in the brain or increase clearance of Aβ may be able to slow the progression of the AD clinical syndrome. AD occurs on a continuum from asymptomatic (preclinical) to mild cognitive impairment (MCI), and then to dementia in mild, moderate, and severe stages. Evidence from both genetic at-risk and age at-risk cohorts, such as in dominantly inherited AD (DIAD) suggests that the pathophysiological process of AD begins well more than a decade before the clinical stage now recognized as AD dementia, and that neurodegeneration is already apparent on MRI by the stage of mild cognitive impairment. Recent clinical trial data suggest that treating AD during the earlier stages could have the greatest potential benefit on the disease by slowing progression
The ability to identify individuals destined to develop Alzheimer's disease (AD) with a high degree of confidence provides a unique opportunity to assess the efficacy of therapies at asymptomatic and very early stages of dementia. Families with known disease-causing mutations are extremely rare and are geographically dispersed throughout the world.
Participants in this study will not yet have developed any clinical symptoms of AD; they will be "asymptomatic" carriers of mutations that cause DIAD and would be expected to perform normally on standard cognitive and functional testing. Further, most mutation carriers will have levels of AD-associated amyloid beta (Aβ) and non-Aβ biomarkers that are the same as non-carriers.
Amyloid beta is a protein that accumulates in the brain of people with AD. Although we do not understand exactly what causes AD, the abnormal accumulation of amyloid beta protein in the brain is thought to play an important role in the symptoms of AD. Recent research studies indicate that amyloid beta may start building up in the brain 15 years or more before the onset of memory loss.
Imaging and fluid biomarkers will be used to demonstrate that the treatment compounds have engaged their therapeutic targets. A set of cognitive measures designed to assess the very earliest and most subtle cognitive changes will be collected. The overall objectives of this study are to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an AD-causing mutation.
The primary objective of Stage 1 is to determine if treatment with the study drug prevents or slows the rate of Aβ pathological disease accumulation demonstrated by Aβ PiB positron emission tomography (PET) imaging.
The primary objective of Stage 2 is to evaluate the effect of early anti-amyloid treatment on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, NfL, MRI volume) compared to a control group from the DIAN Obs natural history study and the DIAN-TU-001 placebo-treated participants.
Remternetug is a monoclonal antibody. The mechanism of action of remternetug is to target and remove aggregated amyloid plaque, a key pathological hallmark of AD, via microglial-mediated clearance. Remternetug has demonstrated the ability to reduce brain amyloid plaque.
The remternetug arm is part of Master Protocol DIAN-TU-002 (NCT05552157)
