Concentrations of unbound sum dabigatran in plasma after 1.92 to 12 h, at steady state of dabigatran, on Day 4 are presented.
The endpoint refers to unbound sum dabigatran at several time points. The intended pharmacodynamic effect of idarucizumab is to reduce the concentration of this measure to levels below the lower limit of quantification (BLQ). "BLQ" values are not considered in the calculation of descriptive statistics; and therefore bias the result. This is the reason for applying the 2/3 rule to obtain reliable results. 2/3 rule states that, Statistics of PK parameters are only estimated when at least 2/3 of the data are evaluable.
Measured: 1.92 hours (h), 2 h, 2.5 h, 6 h and 12 h on Day 4

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Dabigatran and BI 655075 in people with Healthy, run by Boehringer Ingelheim at 1 site in Belgium.
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 1 inclusion and 1 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: finished, as of the sponsor's last update on 23 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 15 Feb 2016). 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 Subjects With Drug Related Adverse Events (AE) (time frame: AEs occurring until end of follow-up (Up to 3 months after last drug administration)). 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 NCT01688830, which also lists 2 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 23 Jun 2016.
