About this study

Official title: A Multicenter, Open-Label, Long-Term Extension Of Phase III Studies (BN29552/BN29553) Of Crenezumab In Patients With Alzheimer's Disease

In the BN40031 OLE study, a dose of crenezumab of 60 mg/kg intravenous (IV) every 4 weeks (Q4W) will be offered to all participants who complete Study BN29552 or BN29553 and who meet eligibility criteria in order to evaluate safety in participants on long-term crenezumab treatment and to investigate the effect of crenezumab on the underlying disease process and disease course as an exploratory efficacy objective.

What is being measured

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

  1. Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An Adverse Event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

    Measured: Baseline up to 16 weeks after the last dose of study drug (up to 54 weeks).

  2. Percentage of Participants With Anti-Crenezumab Antibodies

    Participants were considered positive or negative for ADA based on their baseline and post-baseline sample results. The number and percentage of participants with confirmed positive ADA levels were determined for Crenezumab and Placebo groups. The prevalence of ADA at baseline was calculated as the proportion of participants with confirmed positive ADA levels at baseline relative to the total number of participants with a sample available at baseline. The incidence of treatment-emergent ADAs was determined as the proportion of participants with confirmed post-baseline positive ADAs relative to the total number of participants that had at least one post-baseline sample available for ADA analysis.

    Measured: Baseline up to end of study (up to 54 weeks).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Crenezumab in people with Alzheimer's Disease, run by Hoffmann-La Roche at 66 sites in 16 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 7 inclusion and 11 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 13 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 66 sites in United States, Spain, Canada, Mexico, South Korea and 11 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 phase mean?

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?

Yes. Results are posted in the registry (first posted 9 Jun 2020). 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?

Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Baseline up to 16 weeks after the last dose of study drug (up to 54 weeks).). 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?
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 13 Jul 2020.
