Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Therapy

to evaluate the ability of genotypeguided antithrombotic treatment to reduce adverse clinical events related to arterial thrombosis in PAD patients. Adverse clinical events of interest are major adverse
cardiovascular events (myocardial infarction, stroke, transient ischemic arrack), major adverse limb events (acute/chronic limb ischemia of peripheral vascular intervention including amputation) and death.

Description
A previous version of the Patient Information Form (PIF) was used for participant inclusion at one of the participating sites. The primary difference between the outdated and current versions of the PIF concerns the method of inclusion and sample collection for CYP2C19 genotyping. The most recent PIF specifies the use of remote inclusion via saliva kits, whereas the earlier version described blood sampling as the primary method, with remote inclusion also being possible (e.g. patient preference or absence of further hospital visits).

Although the outdated PIF did still allow for remote inclusion, it did not reflect the newest approved approach described in the latest version submitted to the authorities. As a result, participants at this site were consented based on slightly outdated information regarding the sample collection procedure. This constitutes a deviation from the approved protocol and the authorized patient information, and is therefore being reported as a serious breach in accordance with regulatory requirements.
Sponsor actions
The use of the outdated version of the Patient Information Form (PIF) at this participating site was discovered after the inclusion period of the trial had ended. As a result, no new participants were included using the outdated document after the issue was identified.

The outdated PIF differed from the approved version mainly in the description of the sample collection method for CYP2C19 genotyping (blood sampling as the standard versus remote saliva collection). Although the outdated version still allowed for remote inclusion, it did not reflect the final approved approach as communicated in the most recent PIF.

There is no indication that participants were exposed to increased risk or that their rights were compromised. Data integrity is considered unaffected. However, the use of an outdated PIF version represents a deviation from Good Clinical Practice and applicable regulatory requirements, as participants were not consented using the most recently approved information.
