What is being measured

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

  1. number of patients achieving FXI inhibition ≥ 80% at trough after monthly dosing at 3 dose levels of MAA868 inhibition

    Occurrence of achieving ≥ 80% inhibition of FXI (< 20% free FXI) following 3 months of treatment.

    Measured: month 3

Secondary outcomes (3)
  1. number of patients achieving FXI inhibition ≥ 80% at trough after the first and second dose at 3 dose levels of MAA868

    Occurrence of achieving ≥ 80% inhibition of FXI (< 20% free FXI) at trough on Month 1 and Month 2

    Measured: Month 1 and 2

  2. Number of patients with incidence of major or clinically relevant non-major (CRNM) bleeding events during the treatment period.

    Incidence of major or clinically relevant non-major bleeding events

    Measured: day 1 to day 91

  3. the effect of MAA868 on D dimer and other thrombogenesis biomarkers as indicators of efficacy compared to compotator

    Change from baseline to Day 31, Day 61 and Day 91 in thrombogenesis biomarkers (D-dimer, prothrombin fragment 1.2 (F1.2), thrombin-antithrombin III-complexes (TAT), fibrinogen).

    Measured: Days 31, 61 and 91

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MAA868 and Apixaban in people with Atrial Fibrillation, run by Novartis Pharmaceuticals.

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 5 inclusion and 12 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The record says: withdrawn, as of the sponsor's last update on 8 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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 patients achieving FXI inhibition ≥ 80% at trough after monthly dosing at 3 dose levels of MAA868 inhibition (time frame: month 3). 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 8 Oct 2020.
