What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, TEAEs Leading to Discontinuation of Study Drug, and Fatal TEAEs

    Treatment emergent adverse events (TEAEs) are defined as any adverse event (AE) from the time of study drug administration until 20 weeks after discontinuation of study drug. An AE is defined as any untoward medical occurrence, which does not necessarily have a causal relationship with treatment. A serious AE (SAE) is defined as any event that: results in death; is life-threatening; results in hospitalization or prolongation of hospitalization; is a congenital anomaly; results in persistent or significant disability/incapacity; is an important medical event requiring medical or surgical intervention to prevent serious outcome. Severity of AEs was categorized as mild, moderate, or severe. Relationship of the AE to the study treatment was categorized as having a reasonable possibility or no reasonable possibility.

    Measured: From first dose of study drug to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.

  2. Hematology: Number of Participants With Postbaseline Potentially Clinically Significant (PCS) Values

    Clinical laboratory PCS criteria were adapted from National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

    Measured: Baseline to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.

  3. Clinical Chemistry: Percentage of Participants With Postbaseline PCS Values

    Clinical laboratory PCS criteria were adapted from NCI CTCAE version 4.03

    Measured: Baseline to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.

  4. Columbia-Suicide Severity Rating Scale (C-SSRS) During Double-Blind Treatment Period

    The C-SSRS is a systematically administered instrument developed to track suicidal adverse events across a treatment study. The instrument is designed to assess suicidal behavior and ideation, track and assess all suicidal events, as well as the lethality of attempts. Suicidal ideation categories include the following: wish to be dead; nonspecific active suicidal thoughts; active suicidal ideation without intent to act; active suicidal ideation with some intent to act but no plan; active suicidal ideation with plan and intent. Suicidal behavior categories include the following: actual attempt; interrupted attempt; aborted attempt; preparatory acts or behavior; suicidal behavior; completed suicide.

    Measured: Baseline to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.

  5. Brain Magnetic Resonance Imaging (MRI) Results: Number of Participants With Cerebral Edemas, New Microhemorrhage(s), and Severe White Matter Disease

    Measured: Baseline to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.

Individual data sharing
Yes: AbbVie is committed to responsible data sharing regarding the clinical trials we sponsor. This includes access to anonymized, individual and trial-level data (analysis data sets), as well as other information (e.g., protocols and clinical study reports), as long as the trials are not part of an ongoing or planned regulatory submission. This includes requests for clinical trial data for unlicensed products and indications.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tilavonemab in people with Alzheimer's Disease, run by AbbVie at 57 sites in 10 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 3 inclusion and 3 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: stopped early, as of the sponsor's last update on 22 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 57 sites in United States, Italy, Australia, Spain, Belgium and 5 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this 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.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Sep 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, TEAEs Leading to Discontinuation of Study Drug, and Fatal TEAEs (time frame: From first dose of study drug to 20 weeks after last dose of study drug; overall median time on treatment was 279 days.). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Sep 2022.
