  • If partner is not sterilized, must agree to use highly effective contraceptive measures, methods that can achieve a failure rate of less than 1% per year when used consistently and correctly from screening (V1) until twenty (20) weeks after last dose of any study drug.
  • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, transdermal ii. progestogen-only hormonal contraception associated with inhibition of ovulation: oral, injectable, implantable iii. intra-uterine device (IUD) iv. intrauterine hormone-releasing systems (IUS) v. bilateral tubal occlusion vi. vasectomized partner (only when this is the only partner) vii. true sexual abstinence when this is in line with the preferred and usual lifestyle of the participant. (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parent is deemed a non-carrier through confirmed genetic testing at any time during the study, the participant will be withdrawn.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 is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Stage 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Stage 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.

Read the detailed description

This study will recruit participants from the Dominantly Inherited Alzheimer Network observational study (DIAN-OBS), a multicenter international study supported by the National Institutes of Health (Grant Number U01-AG032438; RJ Bateman), Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU) sites, DIAN-TU partner sites, DIAN Expanded Registry (DIAN-EXR), and families identified by the sites. As part of the DIAN-TU-002 protocol, participants undergo longitudinal assessments that include clinical assessment, cognitive testing, magnetic resonance imaging (MRI) and amyloid imaging, and analysis of cerebrospinal fluid (CSF).

Participants in DIAN are recruited from families that have at least one member who has been identified as having a mutation linked to dominantly inherited Alzheimer's disease (DIAD). The mutations in presenilin 1 (PSEN1), presenilin 2 (PSEN2) and amyloid precursor protein (APP) genes that are associated with DIAD have very high penetrance (near 100%). This study will enroll individuals who are either known to have a known disease-causing mutation, or who are at risk for such a mutation (the child or sibling of a proband with a known mutation) and unaware of their genetic status. Because the age at onset of cognitive changes is relatively consistent within each family and for each mutation, an age at onset is determined for each affected parent or mutation as part of the DIAN-OBS study protocol. This study will enroll participants who are asymptomatic and are within a specific window of time of expected age at onset for their family and/or mutation.

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. These constraints necessitate a specialized study design. Participants in this study will not yet have developed any 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. 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. However, the goal of this study is to address whether decreasing plaque prone Aβ peptides in the absence of measurable or mild elevations of Aβ plaques in participants with minimal to no amyloid plaque at baseline can lead to the subsequent prevention of non-Aβ biomarkers of disease progression. Additionally, because many at-risk individuals decide not to know whether they have the disease-associated mutation, some of the at-risk individuals enrolled in this study will not have the disease-causing mutations; they will be "mutation-negative." It is important to enroll these participants to avoid coercion (e.g., potential participants may feel pressured into genetic testing to learn their genetic status to be eligible for the trial). These mutation-negative individuals will be assigned to the placebo group and data will be used to determine normal ranges of outcome. Participants and site study staff will remain blinded as to these individuals' active or placebo group assignment and mutation status. Thus, the study will be blinded for placebo and for mutation status, except for mutation carriers who are aware of their genetic status. There may be exceptional circumstances as required by local regulation or health authorities where enrollment may be restricted to mutation carriers only, but such mandates will be thoroughly documented and agreed upon by the governing regulatory agency and the study sponsor.

This study is an adaptive-platform-based study. Several different therapies (each referred to as a study drug arm) may be tested in order to increase the likelihood that an effective treatment will be discovered. The compounds are selected for this trial based on mechanism of action and available data on efficacy and safety profile. In the case of multiple study arms, the study design includes a pooled placebo group (referred to as the mutation positive placebos) shared by all study drug arms. Mutation carriers will be assigned to a study drug arm and subsequently randomized within that arm in an overall 1:1 ratio to active drug: placebo. Mutation-negative participants will all receive placebo treatment. Participants and study staff will not be blinded as to which study drug arm each participant has been assigned; they will be blinded to whether participants have been randomized to receive active drug or placebo.

The study has 2 treatment periods: Stage 1 is a blinded placebo-controlled period that will continue until the last randomized participant completes 4 years of treatment (i.e., a common close design), and Stage 2 is an open-label period of 4 years (with a planned 2-year interim efficacy analysis) in which all mutation carriers will receive active drug. At the start of Stage 2, participants who were randomized to placebo in Stage 1 will follow the same dose titration schedule and MRI safety schedule used in Stage 1. Participants who were randomized to active drug in Stage 1 will follow a mock dose titration and will have the same MRI safety schedule used during the initial drug titration as Stage 1 but will remain on the dose that they were on at the end of Stage 1. This will protect the blind to the original treatment assignment from Stage 1. Participants, investigators, and the sponsor's clinical team will remain blinded throughout the study to the Stage 1 treatment assignment.

Stage 1 of the study is designed to test whether the study drug can slow, prevent, or reverse progression of Aβ pathology associated with AD and Stage 2 is designed to assess the study drug's effect on non-amyloid biomarkers of AD that may lead to future slowing or prevention of clinical symptoms of dementia.

Biomarker, cognitive, and/or clinical endpoints will be specified for each study drug arm. Biomarker data will be analyzed for pre-specified endpoints consistent with the drug's mechanism of action and other AD biomarker outcomes. The clinical and cognitive assessments are designed to assess subtle cognitive changes that may be detectable before the onset of dementia as well as cognitive and clinical decline in symptomatic groups.

Roche announced a decision to discontinue most of the company's global trials of gantenerumab. The DIAN-TU has paused the DIAN-TU-002 Primary Prevention Trial related to gantenerumab while considering other potential options for this platform trial.

The DIAN-TU has re-launched the DIAN-TU-002 Primary Prevention Trial with remternetug in collaboration with Eli Lilly and Company as part of this Master Protocol. The remternetug arm is posted under NCT06647498.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Remternetug (SC) in people with Alzheimers Disease and Dementia, run by Washington University School of Medicine at 37 sites in 15 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 27 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in United States, France, Canada, Australia, Germany and 10 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jamie Bartzel (844-DIANEXR (342-6397), dianexr@wustl.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Stage 1: Evaluate the ability of study drug to prevent or slow the rate of Aβ accumulation compared with placebo in participants with mutations that cause DIAD (time frame: Baseline and Week 208). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05552157, which also lists 13 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2026.
